Application of polyurethane shoe anti-yellowing agent in the production of military shoes

1. Introduction: From “Kung Fu on the Foot” to Empowering Technology

Shoes are one of the indispensable inventions in the history of human civilization. From early animal skin wrapping to the application of modern high-tech materials, the development history of shoes has witnessed human continuous pursuit of comfort, functionality and aesthetics. In many fields, military shoes, as a representative of special uses, have far exceeded ordinary civilian shoes. They not only need excellent wear resistance, water resistance and slip resistance, but also meet the stability needs of long-term storage and use. However, during actual use, military shoes often turn yellow due to environmental factors or material aging, which not only affects the appearance, but also may reduce the physical properties of the shoe material.

The problem of yellow change is like an uninvited guest, sneaking into the world of shoe materials, causing many troubles to the production and use of military shoes. Especially in soles or linings made of polyurethane (PU) materials, the molecular structure may change due to ultraviolet irradiation, oxygen oxidation or high temperature, resulting in the color gradually turning yellow or even darkening. This change not only destroys the overall visual effect of military shoes, but may also trigger soldiers’ doubts about their quality, which in turn affects morale and combat efficiency.

To solve this problem, anti-yellowing agents came into being. It is like an invisible protective barrier, which can effectively delay or inhibit the occurrence of yellowing, ensuring that the shoe material still maintains its original color and performance after long-term storage and use. This article will conduct in-depth discussions on the application of polyurethane shoe anti-yellowing agent in military shoes production, from product parameters, mechanism of action to current research at home and abroad, and strive to fully demonstrate the importance of this key technology and its future development direction.

2. Basic concepts and classifications of anti-yellowing agents for polyurethane shoes

(I) What is an anti-yellowing agent?

Anti-yellowing agent is a chemical additive specially used to prevent or slow down the yellowing of materials. Its main function is to prevent or delay the material’s photochemical reaction or thermal oxygen aging by capturing free radicals, absorbing ultraviolet rays or neutralizing acidic substances, thereby protecting the material’s original color and physical properties. For military shoes, the effect of anti-yellowing agent is particularly important because it directly affects whether the shoe material can remain stable under extreme conditions for a long time.

(II) Classification of anti-yellowing agents

Depending on the mechanism of action, anti-yellowing agents can be divided into the following categories:

Category Definition and Features Common Types
Light Stabilizer Absorbs ultraviolet rays and converts them into harmless heat release to avoid yellowing caused by photochemical reactions. UV absorbers (such as benzotriazoles)
Free Radical Capture Catch free radicals generated during material aging, inhibiting chain reactions, thereby reducing the risk of yellowing. Trumped amine antioxidants
Acid neutralizer Neutralize acidic substances produced by degradation inside the material to prevent it from further catalyzing the yellowing reaction. Calcium carbonate, aluminum hydroxide
Compound anti-yellowing agent Combined with multiple mechanisms of action, it provides a more comprehensive protection effect and is suitable for high-performance needs in complex environments. Customized formula mixture

Among them, light stabilizers and free radical capture agents are two commonly used types, especially in polyurethane shoe materials. For example, UV absorbers can effectively shield ultraviolet radiation, while hindered amine antioxidants are good at capturing free radicals. The synergistic effect of the two can significantly improve the anti-yellowing ability of shoe materials.

(III) Why do polyurethane shoes need anti-yellowing agents?

Polyurethane (PU) is a polymer polymer that is widely used in shoe material manufacturing for its excellent elasticity, wear resistance and flexibility. However, PU materials themselves have certain photosensitivity and thermal sensitivity, which are prone to molecular chain breakage or cross-linking reactions under light or high temperature environments, resulting in yellowing of color or even degradation of performance. Therefore, adding appropriate anti-yellowing agents to the production of military shoes can not only extend the service life of the shoe material, but also improve the overall quality and reliability.

3. Analysis of product parameters of polyurethane shoe anti-yellowing agent

In order to better understand the practical application effect of anti-yellowing agents, we take a typical product as an example to analyze its key parameters and their significance in detail.

(I) Basic Product Information

Thermal Stability ?280? Temperature It can remain stable under high temperature processing conditions
Compatibility Good – Good compatibility with PU resin and other additives
Anti-yellowing index ?3 ASTM D6294 Complied with international standards and showed excellent anti-yellowing performance

(II) Detailed explanation of technical indicators

  1. Chemical composition
    The core component of this anti-yellowing agent is a benzotriazole compound, which is an efficient ultraviolet absorber that can selectively absorb ultraviolet rays in the wavelength range and convert its energy into harmless heat to release it, thereby avoiding the yellowing of PU materials due to ultraviolet irradiation.

  2. Add ratio
    The addition ratio directly affects the anti-yellowing effect and cost control. It is generally recommended to control it between 0.5% and 1.0%, which can not only ensure sufficient protection performance without adding too much cost burden. The specific dosage needs to be optimized and adjusted according to the actual production process and target performance.

  3. Thermal Stability
    The production process of military shoes usually involves higher temperature conditions, such as injection molding or vulcanization. Therefore, anti-yellowing agents must have good thermal stability in order to not decompose or fail during the processing process. This product can remain stable below 280?, fully meeting the process requirements of military shoes production.

  4. Anti-yellowing index
    The anti-yellowing index is an important indicator for measuring the performance of anti-yellowing agents and is evaluated by ASTM D6294 standard testing method. The lower the value, the better the anti-yellowing performance. The anti-yellowing index of this product is ?3, indicating that it performs well in practical applications and can effectively delay the occurrence of yellowing.

IV. The mechanism and actual effects of anti-yellowing agent

(I) Analysis of the mechanism of action

The reason why anti-yellowing agents can work is mainly due to their unique molecular structure and chemical properties. Here are some common anti-antibodySpecific mechanism of action of yellowing agent:

  1. The function of light stabilizer
    The light stabilizer prevents the occurrence of photochemical reactions by absorbing ultraviolet light and converting it into heat. Taking benzotriazole compounds as an example, their molecular structure contains specific functional groups, which can preferentially bind to ultraviolet rays to form a stable intermediate state, and avoid the damage to the PU molecular chain by ultraviolet rays.

  2. The role of free radical capture agent
    The main task of free radical capture agents is to capture free radicals generated during material aging, interrupting the propagation of chain reactions. For example, hindered amine antioxidants convert them into stable molecules by providing electrons to free radicals, thereby terminating further oxidation processes.

  3. The function of acid neutralizer
    Acid neutralizers focus on neutralizing acidic substances produced by degradation within the material, preventing these acidic substances from catalyzing other chemical reactions and causing the yellowing to worsen. Common acid neutralizers include calcium carbonate and aluminum hydroxide.

(II) Actual effect display

Through experimental comparison, we can clearly see the significant effect of anti-yellowing agents in the production of military shoes. The following is a typical set of experimental data:

Test items Control group (no anti-yellowing agent added) Experimental group (added anti-yellowing agent) Improvement (%)
Initial Color White White –
Color changes after 72 hours of exposure to UV rays Obvious yellowing Slight yellowing 85%
Tension strength retention rate 75% 95% 27%
Abrasion resistance retention rate 68% 92% 35%

It can be seen from the table that after the addition of anti-yellowing agent, the appearance and physical properties of military shoes have been significantly improved. Even after a long period of UV exposure, the color changes in the experimental group are still very slight, and the tensile strength and wear resistance are effectively protected.Keep.

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

(I) Progress in foreign research

In recent years, European and American countries have achieved many breakthrough results in the field of anti-yellowing agents. For example, BASF, Germany has developed a new composite anti-yellowing agent that integrates the functions of UV absorbers and free radical capture agents, which can provide comprehensive protection in extreme environments. In addition, DuPont, the United States is also exploring the application of intelligent anti-yellowing agents, using nanotechnology to enhance the dispersion and durability of materials.

How to improve the design of indoor shoes with polyurethane shoe material anti-yellowing agent

3月 17th, 2025 News

Polyurethane shoe material anti-yellowing agent: an innovative choice for interior shoe design

1. Introduction: The secret weapon to keep shoes “youthful forever”

In today’s fast-paced living environment, people’s demand for clothing has long surpassed the simple function of sheltering from the wind and rain. A pair of high-quality shoes not only need to be comfortable and durable, but also have the characteristics of lasting and beautiful appearance. However, during actual use, many shoes will experience headaches – yellowing. This phenomenon is like an elegant dancer suddenly being thrown into a bucket of paint, which makes people feel regretful. Especially in the field of indoor shoes, yellowing is particularly prominent due to long-term exposure to environmental factors such as light, heat and air.

Polyurethane (PU) is a polymer material with excellent performance, and has been widely used in the field of shoe materials in recent years. However, traditional polyurethane materials are prone to oxidation reactions under light and high temperature conditions, resulting in the color gradually turning yellow and affecting the appearance quality of the product. In order to solve this problem, scientists have developed a magical “anti-yellowing agent”, which is like an invisible protective shield, can effectively delay or inhibit the yellowing of polyurethane materials. This article will deeply explore the application of polyurethane shoe cotton anti-yellowing agent in indoor shoe design, from principles, parameters to actual cases, and analyze in all aspects how this technology injects the power of “staying youthful” into shoes.

Next, we will reveal how anti-yellowing agents can help designers create more beautiful and durable indoor shoe products through detailed analysis and rich data. At the same time, we will discuss its important position in the modern shoemaking industry based on domestic and foreign literature. Whether you are an industry practitioner or an ordinary reader interested in footwear design, this article will open a door to the future world of shoes.

2. Analysis of the yellowing mechanism: Why do shoes become “old”?

To understand the effects of anti-yellowing agents, we first need to understand the causes of yellowing. Yellowing is a complex chemical process that usually occurs when polymer materials are exposed to specific environmental conditions. For polyurethane shoes, yellowing is mainly caused by the following key factors:

(I) Photooxidation

Ultraviolet rays in the sun are one of the important reasons for the yellowing of polyurethane. When ultraviolet rays hit the polyurethane surface, it stimulates the breaking of chemical bonds inside the material to form free radicals. These free radicals then react with oxygen to create a series of colored substances, such as ketones and quinones. The accumulation of these substances gradually deepens the color of the material and eventually turns out to be a distinct yellow color.

(II) Thermal aging effect

In addition to ultraviolet rays, temperature is also one of the important factors that accelerate yellowing. Under high temperature environments, the movement of the polyurethane molecular chains intensifies, resulting in more chemical bonds breaking, thereby promoting the formation of free radicals. This thermal aging process is similar to the process of rusting of iron tools, except in polyurethaneIt is manifested as a change in color.

(III) Pollutants in the air

The air contains a variety of pollutants that may cause yellowing, such as ozone (O?) and nitrogen oxides (NO?). When these gases come into contact with polyurethane materials, they will trigger a series of complex chemical reactions, further aggravate the yellowing phenomenon. In addition, humidity can also affect the rate of yellowing, because moisture can act as a catalyst to promote the occurrence of certain chemical reactions.

(IV) The influence of material formula

The sensitivity of different types of polyurethane materials to yellowing varies. For example, polyurethanes based on aromatic isocyanates are more likely to yellow than aliphatic isocyanates because the aromatic structure itself has a higher photosensitive nature. Therefore, choosing the right raw material formula is the key to reducing yellowing.

3. Working principle of anti-yellowing agent: wear “invisible armor” on shoes

Anti-yellowing agent is a class of chemical additives specially used to delay or inhibit the yellowing of polymer materials. Its core role is to prevent or slow down the occurrence of the above-mentioned yellowing mechanism through physical and chemical means. The following are the main working principles of anti-yellowing agents:

(I) Absorbing UV rays

Anti-yellowing agents often contain an ingredient called UV Absorber. This type of substance can effectively absorb the energy of ultraviolet rays and convert them into harmless heat energy to release them, thereby avoiding the damage of ultraviolet rays to polyurethane molecules. This effect is similar to the protective effect of sunscreen on human skin, providing shoes with a layer of “invisible sunscreen umbrella”.

(Bi) Scavenge free radicals

Free radicals are an indispensable intermediate product in the yellowing process, while antioxidants in anti-yellowing agents can terminate their chain reaction by capturing free radicals. This mechanism of action is like a firefighter extinguishing a fire, quickly controlling potential hazards and preventing the further spread of yellowing.

(III) Stabilize molecular structure

Certain anti-yellowing agents can also reduce their sensitivity to environmental factors by enhancing the stability of polyurethane molecules. For example, by introducing specific functional groups, the light and heat resistance of the material is improved, thereby fundamentally reducing the possibility of yellowing.

IV. Product parameters and characteristics of polyurethane shoe material anti-yellowing agent

In order to better understand the practical application effect of anti-yellowing agents, we need to conduct a detailed analysis of their key parameters. The following is a technical parameter list of a typical polyurethane shoe material anti-yellowing agent:

parameter name Specific value or range Remarks
Chemical composition UV absorber + antioxidant Mixed Compound Formula
Add ratio 0.5% ~ 2.0% Adjust to specific needs
Light resistance ?E ? 1.0 (400 hours) Test under standard light source
Heat resistance Stay stable at 150? No significant chromatic aberration after long-term high temperature treatment
Compatibility Compatible with common polyurethane systems Do not affect the normal function of other additives
Security Complied with REACH regulations It is harmless to the human body and the environment

From the table above, anti-yellowing agents not only have excellent performance indicators, but also strictly comply with circulation and safety standards, which makes them an ideal choice for the modern shoemaking industry.

5. Advantages of anti-yellowing agents in indoor shoe design

As people’s living standards improve, indoor shoes have gradually become an important part of home life. Whether it’s slippers, home shoes or sports shoes, they all need to meet multiple needs of comfort, durability and aesthetics. The application of anti-yellowing agents is the key to solving these problems.

Simply put, it is like a layer of invisible protective cover that isolates harmful factors and ensures that the shoe material is always as new.

(I) Analysis of the causes of yellowing phenomenon

To understand the importance of anti-yellowing agents, you must first understand the causes of yellowing. During use, polyurethane materials will be affected by multiple factors such as ultraviolet radiation, high-temperature oxidation, and nitrogen oxides in the air. These external conditions will cause double bond breakage or isomerization reactions in polyurethane molecules, thereby producing compounds with color, which will eventually make the shoe material look yellow. This process is like the browning of fruits after being exposed to the air. Although it is a natural phenomenon, it seriously affects the aesthetics and service life of the product.

(II) Mechanism of action of anti-yellowing agent

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

  1. Absorbing UV rays: By adding an ultraviolet light stabilizer, it effectively absorbs and converts ultraviolet energy, reducing its destructive effect on polyurethane molecules.
  2. Antioxidation protection: Use antioxidants to neutralize free radicals, prevent chain propagation of oxidation reactions, thereby delaying material aging.
  3. Capture active substances: By chemically reacting with active substances such as nitrogen oxides, it is converted into harmless substances, and its impact on the material is reduced.

These mechanisms work together to form a strong defense line against yellowing, allowing sports shoes to remain as white as before after long-term use.

2. Application background of polyurethane shoe material anti-yellowing agent
