The role of rubber antioxidants

Rubber antioxidant is a vital chemical additive, mainly used to prevent the performance degradation of rubber materials due to oxidation during storage and use. Such additives can not only significantly extend the service life of rubber products, but also maintain their ideal physical and mechanical properties.

Antioxidant properties

The main function of rubber antioxidants is to prevent the aging of rubber materials by inhibiting oxidation reactions, thereby extending their service life. This chemical can effectively absorb or react with oxygen free radicals, preventing the oxidation process from proceeding.

Compatibility with rubber compounds

When selecting an appropriate rubber antioxidant, one must ensure that it has good compatibility with the rubber compound. This means that antioxidants should not affect the processing properties of the rubber and the properties of the final product.

Key points for choosing rubber antioxidants

Choosing the right rubber antioxidant requires consideration of several factors, the most important of which include antioxidant properties, compatibility, stability and cost-effectiveness. The following are several common types of rubber antioxidants and their characteristics:

Phenolic antioxidants

Phenolic antioxidants have excellent antioxidant properties and are suitable for a variety of rubber materials. They can effectively absorb oxygen free radicals, thereby inhibiting the aging process of rubber. However, its cost is relatively high.

Amine antioxidants

Amine antioxidants perform well under high temperature conditions and can effectively delay the aging of rubber materials. These antioxidants are relatively modest in cost, but in some cases may affect the coloring properties of the rubber.

Phosphorus antioxidants

Phosphorus antioxidants are usually used in rubber products that require extremely high antioxidant properties. They can provide stable antioxidant effects, but their costs are high and there may be process compatibility issues in some links.

Summarize

When selecting rubber antioxidants, factors such as the product's use environment, processing technology, and cost-effectiveness should be comprehensively considered. Through the rational selection and application of suitable antioxidants, the performance and life of rubber products can be significantly improved, thereby achieving higher economic benefits.

Selecting the appropriate rubber antioxidant is a systematic project that requires scientific decision-making based on specific application needs to ensure the best antioxidant effect and overall economic benefits.
