Antioxidant:
Antioxidants are substances that can delay or prevent oxidation and autooxidation processes. Generally some organic compounds with reducing properties. Commonly used in rubber, natural oils, foods, petroleum products and lubricants to prevent oxidation, deterioration, rancidity and gum formation. The antioxidants added to rubber are generally aromatic amines (such as N-phenyl-beta-naphthylamine) and phenolic compounds (such as propyl gallate). The antioxidant added to petroleum products and lubricating oil is mainly to prevent the viscosity change and precipitation of gasoline and lubricating oil, and 2, 6-di-tert-butyl-4-methylphenol and n-butyl-p-aminophenol can be used. The concentration of antioxidants added to food and natural oils is very low, such as the concentration of antioxidants used in animal fats generally does not exceed 0.01%, the maximum allowable concentration is 0.02%, it not only prevents corruption but also makes the nutritional value of long-term storage does not reduce, usually used citric acid, hydroquinone, propyl gallate and so on. The oxidation of polymers is a kind of free radical chain reaction, and the antioxidant can trap the active free radical and generate the inactive free radical, so as to terminate the chain reaction. Or decompose the products of oxidative degradation into non-free radical products, interrupting the chain reaction.
Antioxidants used in polymers are divided into main antioxidants, also known as free radical inhibitors, which include amine compounds such as p-phenylenediamine, diaryl secondary amine, aldehyde amine and ketoamine, as well as phenolic compounds such as antioxidant 264, 1076, 330 and 1010; Auxiliary antioxidant, also known as peroxide decomposition agent, it includes thioesters such as lauryl thiodipropionate and phosphite esters such as triphenyl phosphite two categories. Antioxidants are widely used in natural rubber, synthetic rubber, plastics, synthetic fibers, petroleum products and fatty food processing. Antioxidants used in the rubber industry are commonly referred to as antioxidants. High efficiency, low toxicity, low cost and compound are the main directions of antioxidant development.
