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:

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.

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.

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.

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.

5. Economic Cost

Although excellent performance is an important consideration in choosing composite antioxidants, the economic cost cannot be ignored. Generally speaking, cost-effective antioxidants can achieve the desired effect at a lower amount of addition, thereby reducing the overall cost of use.

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.
