After understanding the rubber aging mechanism, if you want to slow down the speed of rubber aging, the chain growth response in the rubber aging stage is necessary. In rubber consumption, it is necessary to participate in the corresponding antioxidant in the matrix according to the type and application of rubber. Because the molecular chain of the rubber raw material is different, it is necessary to participate in different types of antioxidants. Anti-aging agents are divided into basic anti-aging agents and protective anti-aging agents. The basic anti-aging agents undergo chain reaction of free radicals and thus chain growth reaction. The protective antioxidant is to inhibit the formation of free radicals. The following detailed analysis is suspended for the two types of antioxidants.
