Compound antioxidants: Guardian of green production

In today’s era of pursuing sustainable development, composite antioxidants are gradually becoming star roles in industrial production. It is not only a symbol of technological progress, but also a practitioner of environmental protection concepts. Just like an invisible guardian, silently protecting their lifespan and quality in the world of materials such as plastics, rubbers and polymers. This article will deeply explore the definition, classification, application of composite antioxidants and their important contribution to green production, and will unveil the mystery of this “hero behind the scenes” to you through detailed product parameter analysis and domestic and foreign research data.

What are compound antioxidants?

Composite antioxidants are a mixture of multiple antioxidant components designed to improve the aging resistance of materials. Simply put, it is like putting a protective jacket on the material, which can effectively resist the damage caused to the material by the external environment (such as oxygen, ultraviolet rays, etc.). This additive can not only extend the service life of the product, but also reduce environmental pollution caused by material degradation. Therefore, it is widely used in many fields such as plastics, rubbers, and coatings.

From the chemical structure, composite antioxidants usually contain a variety of ingredients such as main antioxidants (such as hindered phenolic compounds), auxiliary antioxidants (such as phosphite compounds), and stabilizers. These ingredients each perform their own functions and work together to achieve an excellent antioxidant effect. For example, the main antioxidant is responsible for capturing free radicals and preventing the expansion of the oxidation reaction chain; while the auxiliary antioxidant decomposes peroxides, further inhibiting the occurrence of the oxidation process.

Classification and Characteristics of Complex Antioxidants

According to different functional needs, compound antioxidants can be divided into the following categories:

  1. Stealed phenolic composite antioxidants
    This type of antioxidant is known for its excellent free radical capture ability and is often used in polymer materials to delay the occurrence of thermal oxygen aging. Typical representatives include antioxidant 1010, antioxidant 1076, etc.

  2. Phosophite composite antioxidants
    It mainly exerts antioxidant effects by decomposing hydroperoxides and is suitable for materials that require higher transparency or higher color stability.

  3. Thioester compound antioxidants
    It has strong synergistic effects and is especially suitable for antioxidant protection under high temperature conditions.

  4. Multifunctional composite antioxidant
    Combining the above types of features, multiple protection mechanisms can be provided at the same time, and is a popular category of products on the market.

Category Property Description Typical Application
Stealed Phenols Efficiently capture free radicals to prevent chain reaction expansion Polyolefins, engineering plastics
Phosophites Decompose peroxides to improve processing stability Polycarbonate, polyester
Thioesters Synonyms are significant and suitable for high temperature environments Rubber Products
Multifunctional composite antioxidant Comprehensive multiple antioxidant mechanisms, strong adaptability High-end packaging materials

Application scenarios of composite antioxidants

Composite antioxidants have an extremely wide range of applications, covering almost all industries involving polymer materials. Here are some typical examples:

  • Automotive Industry: Adding composite antioxidants to automotive plastic parts can significantly improve the durability and reliability of parts.
  • Food Packaging: By using environmentally friendly composite antioxidants, ensure that the packaging materials will not deteriorate due to oxidation during long-term storage.
  • Building Materials: Adding appropriate composite antioxidants to PVC pipes and boards can enhance their weather resistance and mechanical strength.
  • Electronics: Provides long-lasting antioxidant protection for wire and cable sheaths to ensure the safety of equipment operation.

The promoter of green production

As the global awareness of environmental protection continues to increase, composite antioxidants, as an important part of green production, are playing an increasingly important role. On the one hand, it helps to extend the service life of the material and reduces resource waste; on the other hand, many new composite antioxidants themselves also have good biodegradability, reducing potential harm to the environment.

Study shows that the rational use of composite antioxidants can extend the service life of certain plastic products by more than 50%, which not only means less waste production, but also lower carbon emissions. For example, a German study found that polypropylene film treated with high-efficiency composite antioxidants can maintain excellent physical properties even after multiple recycling.

In addition, some special formula composite antioxidants developed in recent years can even be automatically decomposed under specific conditions intoHarmless substances truly achieve the full environmental protection management of “from cradle to grave”.

Progress in domestic and foreign research

In order to better understand the mechanism of action of composite antioxidants and their optimization direction, scientists have conducted a large number of experimental research. A new report from DuPont in the United States shows that by adjusting the proportion of components in the composite antioxidant, its performance under extreme temperature conditions can be significantly improved. The research team of Toray Co., Ltd. in Japan found that when certain natural-derived antioxidants (such as vitamin E derivatives) are combined with traditional chemical synthetic antioxidants, they can achieve more ideal results.

In China, researchers from the Department of Chemical Engineering of Tsinghua University proposed a new method for preparing composite antioxidant based on nanotechnology. This method can not only greatly improve antioxidant efficiency, but also have better dispersion and compatibility. This innovative achievement provides an important reference for the technological upgrading of relevant industries in my country.

Conclusion

To sum up, composite antioxidants are not only indispensable key additives in modern industry, but also important tools to achieve green production goals. In the future, with the continuous advancement of science and technology, I believe that more efficient and environmentally friendly composite antioxidants will be released, bringing more convenience and safety to our lives.

Application and advantages of composite antioxidants in industrial manufacturing

3月 15th, 2025 News

Compound antioxidants: Invisible Guardian in Industrial Manufacturing

In the vast ocean of industrial manufacturing, there is a magical existence, which is like an unknown guardian, escorting the performance of various materials and products. This is a composite antioxidant—a chemical additive specifically used to delay or inhibit the oxidative degradation of polymer materials. Although its name may sound a bit strange, it has long become an indispensable and important role in the modern industrial system.

Imagine that without the presence of composite antioxidants, plastic products may become fragile and brittle, rubber products may age rapidly and lose elasticity, and even lubricating oils may lose lubricating properties due to oxidation. Behind these seemingly ordinary phenomena, there are actually complex chemical reaction processes hidden. Compound antioxidants effectively prevent or slow down the occurrence of these adverse reactions through their unique chemical mechanism, thereby extending the service life of the material and maintaining its excellent performance.

With the development of technology and changes in market demand, the application scope of composite antioxidants is also expanding. It can be seen from food packaging, household appliances in daily life, to high-end fields such as aerospace and automobile manufacturing. Especially in the context of the current green environmental protection concept becoming increasingly popular, compound antioxidants play an irreplaceable role. It can not only improve the durability of materials and reduce resource waste, but also help reduce production costs and improve product quality, truly achieving a win-win situation between economic benefits and environmental protection.

Next, we will explore the classification, mechanism of action, application fields and their advantages and characteristics of composite antioxidants in depth, and analyze their specific performance in different industries based on actual cases. At the same time, we will also refer to relevant domestic and foreign literature and materials to fully display new research results and development trends in this field. I hope that through the introduction of this article, more people can understand and recognize the important value of composite antioxidants in industrial manufacturing.

Definition and basic principles of composite antioxidants

Composite antioxidant is a multifunctional chemical additive made of scientifically proportioned multiple antioxidant components. It is mainly used to prevent the performance degradation of polymer materials due to oxidation during processing, storage and use. It is like a solid line of defense, always resisting the invasion of harmful substances such as free radicals, ensuring that the material can maintain good physical and chemical properties for a long time. According to its functional characteristics, composite antioxidants can usually be divided into three categories: main antioxidants, auxiliary antioxidants and other functional additives.

The main antioxidant is the core component of the composite antioxidant, which is mainly responsible for capturing and neutralizing free radicals and preventing the propagation of chain oxidation reactions. Common primary antioxidants include phenolic compounds (such as BHT, Irganox series) and amine compounds (such as hindered amines). They terminate the radical chain reaction by providing hydrogen atoms, thus effectively protecting the material from oxidative damage. Auxiliary antioxidants mainly play auxiliary roles, usually including thioesters, phosphites and other substances, which can be decomposed.Peroxide further enhances the overall antioxidant effect. In addition, there are some other functional additives, such as UV absorbers, light stabilizers, etc., which can provide additional protection in specific environments.

The mechanism of action of composite antioxidants can be described in “three steps”: first, it captures free radicals and prevents the start of the chain reaction; second, it decomposes peroxides and cuts off the chain of the oxidation reaction; then it is to remove residual active substances to ensure the safety and stability of the material. This process is like putting a protective clothing on the material so that it can be safe and sound even in the face of harsh environments.

To understand the composition and function of composite antioxidants more intuitively, we can refer to the following table:

Ingredient Type Main Function Common representative substances
Main antioxidant Catch free radicals and terminate chain reaction BHT, Irganox Series
Auxiliary Antioxidants Decompose peroxides to enhance stability Thioesters, phosphites
Functional Adjuvant Provide additional protection to adapt to special environments Ultraviolet absorber, light stabilizer

This multi-level and multi-dimensional protection system allows composite antioxidants to exert excellent performance under various complex conditions, providing reliable technical guarantees for industrial manufacturing.

Classification and application fields of composite antioxidants

Composite antioxidants are important additives in the field of polymer materials. They are of many types and have a wide range of uses.

Below we will use several specific cases to explain in detail the practical application effect of compound antioxidants.

Application in the plastics industry

Plastic products are one of the major application fields of composite antioxidants. Taking polypropylene as an example, as an important general plastic, it is prone to degradation problems due to high temperature oxidation during processing. To solve this problem, manufacturers usually add appropriate amounts of composite antioxidants to the raw materials. For example, a well-known home appliance company adopted the BASF Irganox 1076 and TNPP combination solution, which successfully solved the problem of material discoloration and mechanical performance degradation during injection molding. Experimental data show that the treated polypropylene products can maintain an initial strength of more than 95% after two consecutive years of use, which is much higher than products without antioxidants.

Tension Strength (MPa) 30 45
Elongation of Break (%) 120 200
Impact strength (kJ/m²) 4 8

Application in the rubber industry

Rubber products are very susceptible to the influence of oxygen and ultraviolet rays due to long-term exposure to the air. To this end, many tire manufacturers have begun to use composite antioxidants to improve the durability of their products. For example, Michelin introduced Lanxess series of amine antioxidants into its high-performance tire formula, significantly extending the life of the tire. Test results show that the improved tires have a wear rate reduced by 30% under simulated road conditions while maintaining good grip and comfort.

More importantly, how will compound antioxidants play a key role under the future high standards of market demand? This article will take you to understand the mysteries of this field in depth, explore its technical principles, application prospects and development trends, and uncover the wonderful world behind compound antioxidants through detailed data and vivid metaphors.

1. Basic concepts and mechanism of action of composite antioxidants

(I) Definition and Classification

Composite antioxidant is a functional additive composed of a variety of single antioxidants in a specific proportion. It is mainly used to delay or inhibit the performance degradation caused by oxidation of materials during processing, storage and use. According to its functional characteristics, composite antioxidants can be divided into the following categories:

  1. Free radical capture antioxidants: By capturing free radicals (such as·OH, ROO·, etc.), the chain oxidation reaction is interrupted to protect the material from damage.
  2. peroxide decomposition antioxidants: By decomposing peroxide intermediates, it reduces its destructive effect on the material structure.
  3. Metal ion passivation antioxidants: By chelating metal ions (such as Fe³?, Cu²?, etc.), they reduce their catalytic effects on oxidation reactions.
  4. Auxiliary antioxidant: Works in concert with other types of antioxidants to further enhance the overall antioxidant effect.

It is worth noting that composite antioxidants do not simply mix different types of monomeric antioxidants together, but are carefully designed and optimized to ensure a good synergistic effect between the components, thereby achieving the effect of “1+1>2”.

(Bi) Analysis of the mechanism of action

The mechanism of action of composite antioxidants can be described in a figurative metaphor: if the oxidation reaction is a raging forest fire, then composite antioxidants are a well-trained fire brigade. The following is its specific “fire extinguishing” process:

  1. Initial Prevention: Through metal ion passivation antioxidants, the “fire” that may cause fires – metal catalysts.
  2. Medium-term control: Use free radical capture antioxidants to quickly extinguish the formed flame – free radicals.
  3. Later-stage consolidation: Use peroxide decomposition antioxidants to prevent the residual smoke – peroxide from continuing to spread.
  4. Full-process guarantee: Rely on auxiliary antioxidants to provide logistical support to the entire team to ensure efficient completion of fire extinguishing operations.

This multi-layer and multi-dimensional protection strategy allows composite antioxidants to show excellent antioxidant properties in complex environments.

(III) Advantage Analysis

Combined antioxidants have the following significant advantages compared to single antioxidants:

Project Single Antioxidant Compound antioxidants
Antioxidation efficiency Lower Sharp improvement
Scope of use Limited Widely applicable
Cost-effective Higher More economical
