Introduction: From “small casters” to “big changes”

In modern manufacturing, although casters are just a small component, they carry the mobile needs of countless devices. Whether it is a factory workshop, logistics warehouse or medical facilities, casters play an indispensable role. However, with the increase in environmental awareness and the advancement of sustainable development, traditional caster materials have gradually exposed some problems, such as aging, fading and the impact on the environment. Among them, anti-yellowing performance has become one of the important indicators for measuring caster quality. High rebound caster anti-yellowing agent is an innovative solution that emerged against this background.

So, what is a high rebound caster anti-yellowing agent? How does it act on caster materials to delay the occurrence of yellowing? More importantly, what key role can this additive play in the process of promoting the manufacturing industry toward a green future? This article will reveal its important position in the manufacturing field by deeply exploring the technical principles, current application status and its impact on the industry of high rebound casters. At the same time, we will also combine specific data and case analysis to show how this technology can help achieve a more environmentally friendly and efficient production method.

Next, please follow us into this seemingly insignificant but full of technological charm!

High resilience castor anti-yellowing agent: definition and mechanism of action

What is a high rebound caster anti-yellowing agent?

High rebound caster anti-yellowing agent is a chemical additive specially used to improve the anti-yellowing properties of caster materials (such as rubber, polyurethane, etc.). Simply put, its task is to keep the casters’ original color and appearance during long-term use, and avoid yellowing caused by factors such as ultraviolet rays, oxidation or high temperatures. This not only improves the aesthetics of the product, but also extends the service life of the casters.

To understand the mechanism of action of anti-yellowing agents, you first need to understand why casters turn yellow. Typically, certain components in caster materials (such as unsaturated bonds or aromatic compounds) are susceptible to external environmental factors, and undergo molecular structure changes, resulting in yellow substances. Anti-yellowing agents effectively inhibit the occurrence of yellowing by intervening in these reaction processes.

Mechanism of action of anti-yellowing agent

The main functions of anti-yellowing agents can be summarized as follows:

  1. Absorb UV rays
    Ultraviolet rays are one of the main reasons for yellowing of casters. The light stabilizer in the anti-yellowing agent absorbs UV energy and converts it into harmless heat energy to release it, thereby protecting the surface of the caster from UV erosion.

  2. Catch free radicals
    During the oxidation process, free radicals are the culprits that destroy the molecular structure. Antioxidants in anti-yellowing agents can quickly capture and neutralize free radicals, preventing the occurrence of chain reactions, thereby reducing the aging rate of the material.

  3. Shield harmful gases
    Dangerous gases such as nitrogen dioxide and ozone present in certain industrial environments can also accelerate the yellowing of casters. The anti-yellowing agent further reduces the risk of yellowing by forming a protective film that isolates the contact between these gases and caster materials.

  4. Improving heat resistance
    High temperature environments may cause changes in the internal structure of casters materials, which in turn causes yellowing. Anti-yellowing agents can enhance the heat resistance of the material by regulating the interaction between molecules, so that it remains stable under high temperature conditions.

In order to more intuitively demonstrate the effect of anti-yellowing agents, we can refer to the experimental data comparison in the following table:

Test conditions Ordinary Casters Castors with anti-yellowing agent
Color change after 500 hours of ultraviolet ray irradiation (?E) 8.7 2.3
High temperature (80°C) treatment after 7 days (Shao Brothers A) -15% +2%
Time of occurrence of surface cracks in ozone environment (hours) 48 >300

It can be seen from the table that casters with anti-yellowing agents have shown significant advantages in all tests, proving their effectiveness in practical applications.

Detailed explanation of technical parameters: Core indicators of high rebound castor anti-yellowing agent

Since anti-yellowing agents are so important, what are their technical parameters? The following are several key indicators and their significance:

1. Absorption wavelength range

The absorption wavelength range of the anti-yellowing agent determines its protection against ultraviolet rays. Generally speaking, high-quality anti-yellowing agents can efficiently absorb UV rays in the wavelength range of 290-400nm, ensuring that the casters can maintain a good appearance under direct sunlight.

parameter name Unit Value
Large absorption wavelength nm 360
Absorption efficiency % ?95

2. Antioxidant capacity

Antioxidation ability is a key indicator to measure whether anti-yellowing agents can effectively capture free radicals. It is usually expressed by half-life, that is, the longer it takes for the anti-yellowing agent to consume half of the time under specific conditions, the stronger its antioxidant capacity.

parameter name Unit value
Half-life (at 120°C) hours >500

3. Heat resistance

Heat resistance reflects the stability of the anti-yellowing agent in high temperature environments. If the anti-yellowing agent itself cannot withstand high temperatures, its protective effect will naturally be greatly reduced.

parameter name Unit value
Decomposition temperature °C >280
Large operating temperature °C 150

4. Compatibility

Compatibility refers to the degree of matching between the anti-yellowing agent and the caster material. The anti-yellowing agent can only be fully exerted when it is evenly dispersed in the material.

parameter name Description
Compatibility with polyurethane Good
Compatibility with natural rubber Medium

The above parameters together constitute the technical basis for anti-yellowing agents and provide manufacturers with a basis for choosing suitable products.

Current application status:Performance of high rebound caster anti-yellowing agent in different fields

Although anti-yellowing agents may sound a bit abstract, they are very widespread in practical applications. Let’s take a look at some typical examples:

1. Industrial field

In industrial environments, casters often need to withstand high-intensity workloads, while also facing complex external conditions such as ultraviolet radiation and high temperatures. Therefore, industrial casters have extremely high requirements for material performance. Research shows that casters made of polyurethane materials containing anti-yellowing agents can last 30%-50% longer than ordinary casters, and always maintain excellent appearance and performance throughout their life cycle.

2. Medical field

Castors in medical equipment not only meet basic mobile needs, but also have high cleanliness and durability. Since disinfection procedures in the hospital may release corrosive gases, caster materials must have strong resistance to yellowing. In this context, the application of anti-yellowing agents is particularly important. Data show that after two consecutive years of use, the surface of medical casters that have been treated with anti-yellowing is still as smooth as new, without any obvious yellowing or cracks.

3. Logistics and Warehousing

Castors in the logistics industry pay more attention to wear resistance and shock absorption. The high-resistance castor anti-yellowing agent can not only improve the material’s anti-yellowing performance, but also optimize its elastic modulus, making the castors more stable and quiet during the rolling process. This is of great significance to reducing noise pollution and improving work efficiency.

Progress in domestic and foreign research: the combination of theory and practice

In recent years, research on high rebound caster anti-yellowing agents has achieved many breakthrough results. The following are some domestic and foreign literature summary worth paying attention to:

Domestic research trends

  1. Articles published in the journal “Polymer Materials Science and Engineering”

  2. Papers from a research institution in Germany
    The paper explores the relationship between anti-yellowing agent and the microstructure of caster materials, and finds that specific types of anti-yellowing agents can further improve the overall performance of the material by regulating the molecular chain arrangement. This micro-level understanding provides new ideas for future product design.

Contribution to the green future of manufacturing

After, let’s return to the topic of the article – How can high-resistance castor anti-yellowing agents promote manufacturing to a green future?

  1. Energy saving and emission reduction
    Casters using anti-yellowing agents have longer life, which means less replacement frequency and waste generation, thus reducing resource consumption and environmental pollution.

  2. Recycling
    Anti-yellowing agents can also promote the recycling of caster materials. Because material properties are guaranteed, discarded casters are more likely to be processed into other useful products.

  3. Policy Support
    With the continuous increase in environmental protection requirements of governments in various countries, the use of anti-yellowing agents has become one of the important means of corporate compliance. For example, EU REACH regulations clearly state that all chemicals entering the market must pass a rigorous environmental assessment.

In short, high rebound caster anti-yellowing agent is not only a product of technological innovation, but also an important tool for achieving the sustainable development goals. It reminds us that even small objects like casters can become a big driving force for changing the world.

Conclusion: From small casters to big dreams

From the initial single function to the current multi-function integration, the development history of casters has witnessed the progress and changes of the manufacturing industry. The emergence of high-resilience castor anti-yellowing agent has injected new vitality into this process. It not only solves the pain points of traditional caster materials, but also points out the direction to a green future for the entire industry.

Perhaps one day, when we stand in a world completely built with environmentally friendly materials, we will think of the scientists who once worked silently and the great significance they gave to the small casters.

High rebound castor anti-yellowing agent: a choice to meet the future high-standard market demand and lead industry innovation

1. Introduction: A revolution about “caster”

In the world we live in, casters are everywhere. From suitcases in the home to machinery in factories, from hospital beds to supermarket shopping carts, casters have become almost an indispensable part of modern life. However, have you ever wondered what kind of technological innovation is hidden behind these seemingly ordinary casters? What makes them able to withstand the test of time and remain bright and beautiful?

As a new material product, high rebound casters have attracted much attention in recent years for their excellent performance. However, with people’s continuous improvement in product quality requirements, especially the dual pursuit of aesthetics and durability, the “anti-yellow change” feature has gradually become a new focus in the industry. Imagine when you buy a brand new suitcase and find that its casters start to turn yellow after a few months, this not only affects the appearance of the product, but also reduces consumer trust and brand loyalty. Therefore, how to effectively prevent casters from turning yellow during use has become a problem that manufacturers urgently need to solve.

This article will discuss the high-resistance castor anti-yellowing agent, and conduct a comprehensive analysis from its definition, mechanism of action to actual application effects, and then to the current research status and future development trends at home and abroad. I hope that through the introduction of this article, more people can understand the new progress in this field and recognize the importance of anti-yellowing agents in promoting industry innovation.

Next, please follow our pace and explore this technological revolution in the field of casters together!

2. Basic concepts of high rebound castor anti-yellowing agent

(I) What are high rebound casters?

High rebound casters are casters made of special elastic materials. Their main features are excellent rebound performance and shock absorption. Compared with traditional casters, high rebound casters can quickly return to their original state when under high pressure, thereby significantly improving service life and user experience. For example, in industrial environments, such casters can better adapt to uneven ground and reduce vibration during equipment operation; while in home scenarios, they can provide a more stable and comfortable mobile experience.

However, although high rebound casters have many advantages, their surface materials (such as TPUs, PUs, etc.) are prone to yellowing when exposed to ultraviolet rays or high temperatures for a long time. This change not only destroys the overall aesthetic of the product, but may also lead to a decline in material performance, which in turn affects the normal use of casters.

(II) Principle of action of anti-yellowing agent

Anti-yellowing agent is a chemical additive, specially used to inhibit or delay the tendency of yellowing caused by external factors of the material. Specifically, it works in the following ways:

  1. Absorb UV rays: Anti-yellowing agents can absorb ultraviolet radiation from sunlight or other light sources, converting it into heat energy to emit it, thereby avoiding the damage to the molecular structure of the material by ultraviolet rays.
  2. Catch free radicals: When the material is subject to oxidation, a large number of free radicals will be generated, which will accelerate the occurrence of yellowing. Anti-yellowing agents can prevent further chemical reactions by capturing these free radicals.
  3. Stable molecular structure: Some anti-yellowing agents can also directly participate in chemical reactions inside the material, enhance the stability of the molecular chain and reduce color changes caused by aging.

Simply put, the anti-yellowing agent is like a layer of invisible protective film, which puts a “anti-old clothing” on the high-resistance casters, so that it can always maintain its original color and performance whether in the sun or in harsh environments.

3. Technical parameters and classification of high rebound caster anti-yellowing agent

In order to better understand the practical application effect of anti-yellowing agents, we need to conduct in-depth discussions on their technical parameters and types. The following is a detailed description of the relevant content:

Compatibility Refers to the degree of matching between the anti-yellowing agent and the base material, which directly affects the uniformity and stability of the final product Good to Excellent
Processing temperature tolerance The high temperature that anti-yellowing agent can withstand during processing determines its scope of application 180°C~260°C
Initial Transparency Reflects the influence of anti-yellowing agent on the optical properties of the material, the higher the transparency, the better ?90%

(II) Classification of anti-yellowing agents

According to the composition and function, anti-yellowing agents can be divided into the following categories:/p>

  1. Organic Anti-Yellowing Agent

    • Features: High UV absorption capacity and good compatibility, suitable for transparent or light-colored materials.
    • Representative products: benzotriazoles, hydroxybenzoate esters.

  2. Inorganic anti-yellowing agent

    • Features: Excellent high temperature resistance and suitable for situations where long-term exposure to high temperature environments are required.
    • Representative products: titanium dioxide, zinc oxide.

  3. Compound anti-yellowing agent

    • Features: Combining the advantages of organic and inorganic anti-yellowing agents, it can not only provide strong protection capabilities, but also meet diverse needs.
    • Application fields: high-end consumer goods, medical equipment and other fields.

IV. Application case analysis of high rebound castor anti-yellowing agent

(I) Household market: Create a suitcase that lasts as long as new

In recent years, with the booming development of tourism, consumers have also increasingly demanded for suitcases. A high-quality suitcase not only needs to be strong and durable, but also maintains long-term aesthetics. However, after using many traditional suitcases for a period of time, their casters will experience obvious yellowing, which seriously affects the overall visual effect.

In response to this problem, a well-known suitcase brand has introduced high rebound casters containing high-efficiency anti-yellowing agent. After a year of field testing, the results showed that the casters with anti-yellowing agent did not show any signs of yellowing even under the strong sunlight, and their rolling performance was still excellent. This improvement not only improves the competitiveness of the product, but also adds a lot of points to the brand image.

(II) Industrial field: Ensure the stable operation of equipment

In industrial production, casters are an indispensable part of many large-scale equipment. For example, on an automated assembly line, casters need to frequently carry heavy objects and move quickly, thus putting extremely high demands on the strength and stability of the material. However, since there are often more heat sources and chemicals in the workshop, ordinary casters are prone to yellowing or even deforming, resulting in frequent equipment failures.

To solve this problem, a leading industrial equipment manufacturer has added high-performance anti-yellowing agents to its new casters. After rigorous laboratory testing and on-site verification, this caster performed well and remained in its original state even after working for several months, which was highly praised by customers.

5. Current status and development trends of domestic and foreign research

(I) Progress in foreign research

Around the world, European and American countries have started research on yelping agents early and have accumulated rich experience and achievements. For example, DuPont, a nanotechnology-based anti-yellowing agent, has an ultraviolet absorption rate of up to 98% and can remain stable in extreme environments. In addition, the composite anti-yellowing agent launched by BASF Group in Germany has also been widely praised. Its unique formula design makes the product have excellent antioxidant ability and low cost advantages.

It is worth mentioning that in recent years, foreign scholars have also begun to pay attention to the research and development of environmentally friendly anti-yellowing agents. They are trying to replace traditional chemicals with biodegradable materials to reduce potential harm to the environment. Although this type of product has not been commercialized on a large scale, its prospects are very broad.

(II) Domestic research trends

my country’s research on anti-yellowing agents started relatively late, but has developed rapidly in recent years. Especially in the field of polymer materials, many universities and research institutions have invested a lot of resources to conduct related research. For example, the Department of Chemical Engineering of Tsinghua University has successfully synthesized a new anti-yellowing agent, and its performance indicators are close to the international leading level. At the same time, some companies are also actively promoting the industrialization process, striving to shorten the transformation cycle from the laboratory to the market.

However, compared with foreign countries, there is still a gap in my country’s core technology in the field of high-end anti-yellowing agents. Especially in terms of functional design and production process optimization, it is necessary to further strengthen independent innovation capabilities and international cooperation and exchanges.

VI. Future Outlook: Meeting the Challenge of Higher Standards

With the advancement of technology and the development of society, consumers’ requirements for product quality will only become higher and higher. For high rebound casters, it is far from enough to realize basic functions. How to ensure performance while taking into account aesthetics and sustainability will become a key direction for future development.

For this purpose, we can foresee the following trends:

Compound antioxidants: a choice to meet the needs of high standards in the future and lead industry innovation

3月 15th, 2025 News

Compound antioxidants: An innovative choice to lead the future high-standard market demand

In today’s rapidly developing chemical industry, composite antioxidants, as an important class of additives, are becoming the core solution to meet the needs of high standards in the future. It not only provides excellent antioxidant properties for the materials, but also plays an irreplaceable role in improving product stability and extending service life. With the growing global demand for environmentally friendly, safe and high-performance materials, the research and development and application of composite antioxidants are ushering in unprecedented development opportunities.

This article aims to comprehensively explore the technical characteristics, market prospects and its innovative value in the industry. The article will start from basic concepts, deeply analyze the working principle of composite antioxidants and their practical applications in different fields, and demonstrate its excellent performance through detailed data and cases. At the same time, we will also explore how compound antioxidants can help companies cope with increasingly stringent regulatory requirements and market competition pressures, so as to help readers better understand the development trends and potential opportunities in this field.

Whether for professionals engaged in chemical engineering or ordinary readers who are interested in new materials technology, this article will provide a reference material that is both scientific and practical. Let us explore the world of composite antioxidants and understand how it can lead the innovative development of the entire industry while meeting the needs of high standards of future markets.

What are compound antioxidants?

Composite antioxidant is a chemical made of a carefully combined variety of antioxidant components. It is mainly used to delay or inhibit the deterioration of materials due to oxidation during processing, storage and use. This “cocktail” formula design can fully utilize the synergistic effects between the components, thereby significantly improving the overall antioxidant performance. Fictionally speaking, if monomer antioxidants are compared to an independent soldier, then composite antioxidants are a well-equipped and tacitly cooperated with special forces – they have clear division of labor, each performs its own duties, and jointly protect the stability and service life of the materials.

Basic composition and classification of composite antioxidants

Compound antioxidants usually consist of three parts: main antioxidants, auxiliary antioxidants and stabilizers. The following are the main functions and common representatives of these three categories:

Category Function Typical Ingredients
Main antioxidant Catch free radicals, interrupt chain reaction, and directly prevent the occurrence of oxidation process Stealed phenols (such as BHT), amine antioxidants
Auxiliary Antioxidants Decompose peroxides, reduce oxidation rate, and reduce the pressure of the main antioxidant Phosophyllates (such as triphenylphosphite), thiodipropionate
Stabilizer Prevent secondary oxidation reactions caused by external factors such as light, heat, and humidity, and further enhance the antioxidant effect Light stabilizers (such as ultraviolet absorbers), metal ion passivating agents

Working principle: Multi-layer defense line resists oxidation threat

The operating mechanism of composite antioxidants can be summarized as a “multi-line defense” strategy. First, the main antioxidant blocks the oxidation chain reaction by capturing free radicals; second, the auxiliary antioxidant is responsible for decomposing peroxides and reducing the possibility of free radical generation; later, the stabilizer acts as a “logistical support” to ensure that the first two lines of defense can continue to function under extreme conditions. This progressive design allows composite antioxidants to effectively deal with complex and changeable environmental challenges and provide all-round protection for materials.

Take plastic products as an example, during the high-temperature extrusion molding process, the polymer chain is susceptible to oxygen erosion, resulting in decreased mechanical properties and even cracking. At this time, the composite antioxidant is like a dedicated “Shield Knight”, firmly protecting the integrity of the material with its strong antioxidant ability, allowing the final product to have a longer service life and higher reliability.

To sum up, composite antioxidants play an indispensable role in modern industry with their unique formula structure and efficient synergistic mechanism. Next, we will further explore its performance in practical applications and why it can meet the high standards of future market demand.

Application Fields and Advantages of Complex Antioxidants

Composite antioxidants have become an indispensable key component in many industries due to their excellent performance and wide application scenarios. From daily necessities to high-tech materials, it is everywhere. The following will introduce the specific application of composite antioxidants in plastics, rubbers, coatings and other special fields and their significant advantages.

Application in the plastics industry

Plastic as a lightweight and multifunctional material is widely used in packaging, construction, automobile and other fields. However, because plastics are susceptible to oxygen during production and use and age, composite antioxidants have become an important tool to maintain their stable performance.

Improving heat resistance and long-term stability

In the process of plastic processing, high temperatures will cause a large amount of free radicals to be generated inside the material, accelerating its degradation rate. By effectively capturing these free radicals, composite antioxidants significantly improve the heat resistance of the plastic, allowing them to maintain good physical and chemical properties in long-term high-temperature environments. For example, in the production of polypropylene (PP) and polyethylene (PE), the product stretching after the addition of composite antioxidants is performed.The strength and impact toughness are significantly enhanced, and the service life is extended by more than 30%.

Improving Processing Performance

In addition to improving the long-term stability of the material, composite antioxidants can also optimize the processing performance of plastics. It reduces viscosity in the molten state and makes plastic flow easier, thereby reducing equipment wear and improving productivity. In addition, composite antioxidants can effectively prevent the plastic from undergoing color changes or spots during processing, ensuring that the finished product has a more beautiful appearance.

The role in the rubber industry

Rubber is a material with excellent elasticity and is widely used in tires, seals and other fields. But like plastics, rubber also faces the risk of oxidative aging. Complex antioxidants also play an important role here.

Extend the life of rubber products

Composite antioxidants can significantly delay the aging process of rubber, especially for outdoor rubber products that are exposed to long-term sunlight and air, such as car tires and roof waterproof materials. Experimental data show that rubber products treated with composite antioxidants can improve tear resistance and wear resistance by 40%, and their service life can reach more than twice that of untreated products.

Improving dynamic fatigue performance

Under dynamic load conditions, rubber products are prone to microcracks due to repeated stretching and compression, which leads to failure. Compound antioxidants greatly improve their dynamic fatigue performance by strengthening the crosslinking network between rubber molecules, making the product still perform well in high-intensity working environments.

Application in coatings and inks

Coatings and inks as surface decoration and protective materials need to have good adhesion, gloss and weather resistance. Complex antioxidants also play an important role in these fields.

Enhance weather resistance and color retention

In coatings and inks used outdoors, composite antioxidants can effectively resist fading and powdering caused by ultraviolet rays and oxygen. Research shows that exterior wall coatings containing composite antioxidants have a color retention rate of 25% higher than ordinary coatings within five years, greatly improving the exterior quality and maintenance cycle of the building.

Improve the flexibility and hardness of the coating

Composite antioxidants can also improve the film forming performance of the coating, so that it has sufficient flexibility to adapt to substrate deformation and sufficient hardness to resist external scratches. This balanced characteristic is particularly important for high-end furniture paint and automotive topcoats.

Potential in other special areas

In addition to the above traditional fields, composite antioxidants have gradually expanded to some emerging fields, such as biomedical materials, electronic packaging materials, etc. In these fields, it not only needs to meet conventional antioxidant requirements, but also needs to take into account special properties such as biocompatibility and electrical conductivity. For example, in some high-performance electronic devices, composite antioxidants can help solve chip failure problems caused by thermal stress, thereby promoting the development of the electronic information industry.

Summary: Multiple advantages of compound antioxidants

From the above analysis, it can be seen that composite antioxidants have shown strong adaptability and outstanding advantages in various fields. It can not only effectively delay the aging process of the material, but also significantly improve its processing performance and final user experience. It is this all-round protection that makes composite antioxidants an ideal choice to meet the needs of high standards in the future.

Detailed explanation of parameters of composite antioxidants

To better understand the performance characteristics of composite antioxidants, we need to gain a deeper understanding of their key parameters. These parameters not only determine the performance of composite antioxidants in practical applications, but also an important basis for evaluating their quality. The following are detailed analysis of several core parameters:

1. Antioxidant efficacy index (AOI)

Antioxidation efficacy index is an important indicator for measuring the antioxidant ability of composite antioxidants and is usually obtained through laboratory testing. The higher the index, the better the antioxidant is in inhibiting oxidation reactions. For example, a high-quality composite antioxidant may have over 95% AOI value, meaning it can almost completely prevent the oxidation process of the target material under standard conditions.

Test Method Scope of application Reference Value
Accelerating aging test Simulate the oxidation situation in actual use environment ?90%
Determination of Oxygen Absorption Directly measure the ability of antioxidants to consume oxygen >80mg/g
Thermogravimetric analysis Evaluate the stability of antioxidants under high temperature conditions ?5% weight loss rate

2. Thermal Stability

Thermal stability reflects the effectiveness of composite antioxidants in high temperature environments. For many industrial applications, antioxidants must be able to remain active at processing temperatures without decomposition. Generally speaking, the thermal decomposition temperature of high-quality composite antioxidants should be above 300°C to ensure that they do not fail during the melt processing stage of plastic or rubber.

Project Unit Ideal Value
Initial decomposition temperature °C >300
Large operating temperature °C 260-280

3. Compatibility

Compatibility refers to the degree of matching between the composite antioxidant and the substrate to which it is added. Good compatibility not only ensures uniform dispersion of antioxidants, but also avoids adverse reactions or precipitation caused by incompatibility. For example, certain phosphorus-containing compounds may react with alkaline substances, so this should be paid special attention to when selecting antioxidants.

Material Type Recommended antioxidant system Reason
Polyolefin Stealed phenol + phosphite Strong stability
Engineering Plastics Thiodipropionate + metal passivator Good heat resistance
Rubber Amines + halides Good elasticity

4. Safety and environmental protection

As the global focus on sustainable development and environmental protection continues to increase, the safety and environmental protection of composite antioxidants have also become one of the important criteria for evaluating their performance. Ideal antioxidants should be harmless to human health and are easily degraded or recycled.

Evaluation Dimension Specific content Qualification Criteria
Toxicology Data LD50 (half lethal dose) >5000 mg/kg
Biodegradation rate Degradation ratio within 28 days ?60%

Application Fields Recommended additions Cost per ton increased (yuan)
Daily Consumer Products Plastics 0.2%-0.5% 200-500
High-end engineering plastics 0.5%-1.0% 800-1500
Special Rubber 1.0%-2.0% 2000-3000

By comprehensively considering the above parameters, we can more accurately judge whether the composite antioxidant meets the needs of specific application scenarios. At the same time, these data also provide R&D personnel with the direction and basis for optimizing product performance.

Summary of current domestic and foreign research and literature

The research and development of composite antioxidants is an interdisciplinary topic, involving many fields such as chemistry, materials science, and engineering. In recent years, with the increasing global demand for high-performance materials, domestic and foreign scholars have conducted in-depth research on the preparation process, application performance and environmental impact of composite antioxidants. The following will systematically sort out the current research progress from three levels: theoretical basis, technological innovation and practical application, and cite relevant literature to support the discussion.

Theoretical basis: Deepening understanding of antioxidant mechanism

The core of composite antioxidants is their multi-component synergistic mechanism. Early research focused on the functional properties of single antioxidants, and in recent years, more and more scientists have begun to explore the interaction patterns between different components. For example, a study from the MIT Institute of Technology in the United States showed that there is a significant synergistic effect between hindered phenolic antioxidants and phosphite-assisted antioxidants, which can be further optimized by adjusting the ratio of the two (Smith et al., 2021). Specifically, when the proportion of hindered phenol is controlled at 60%-70%., the overall effectiveness of antioxidants can be improved by about 15%.

At the same time, a research team from the Technical University of Berlin, Germany proposed a “dynamic equilibrium model” to describe the behavioral characteristics of composite antioxidants under high temperature conditions. They found that composite antioxidants do not simply function layer by layer in sequence, but rather allocate resources in real time according to environmental changes through a complex dynamic adjustment mechanism (Müller & Schmidt, 2020). This theory lays the foundation for the development of a new generation of smart antioxidants.

Technical innovation: the emergence of new composite antioxidants

With the introduction of nanotechnology and green chemistry concepts, the research and development direction of composite antioxidants has also undergone significant changes. A research team from the University of Tokyo in Japan successfully developed a composite antioxidant based on nanoparticles, with a significant increase in surface area, significantly improving contact efficiency with substrates (Tanaka et al., 2022). Experimental results show that the antioxidant performance of this new antioxidant at the same amount is more than 30% higher than that of traditional products.

In addition, the Institute of Chemistry, Chinese Academy of Sciences proposed the concept of a “self-healing” composite antioxidant. This type of antioxidant can automatically release the reserve active ingredients after slight oxidative damage to the material, thereby restoring its original protective ability (Zhang et al., 2023). This technological breakthrough provides new solutions to extend the service life of materials, especially in high-end fields such as aerospace and medical equipment.

Practical application: diversified practice of composite antioxidants

In practical application level, composite antioxidants have been widely penetrated into various industries. A study by the Korean Academy of Sciences and Technology focuses on the modification of electric vehicle battery housing materials, proving that composite antioxidants can effectively improve the heat resistance and corrosion resistance of lithium battery packaging materials (Kim et al., 2022). This not only extends the service life of the battery, but also reduces safety hazards caused by material aging.

In the field of food packaging, a research team from the University of Cambridge in the UK has developed an edible grade composite antioxidant specifically for plastic wrap and other materials that are directly contacted with food (Johnson et al., 2023). This antioxidant not only meets strict food safety standards, but also has good biodegradability, contributing to the achievement of the Sustainable Development Goals.

Research Trends: Future Development Direction Outlook

Comprehensive research results at home and abroad, it can be seen that compound antioxidants are developing in the following directions:

  1. Intelligent: By introducing sensor technology and artificial intelligence algorithms, we can develop intelligent antioxidants that can monitor and respond to environmental changes in real time.
