The aging property of radiation vulcanized natural rubber was studied using various kinds of antioxidants.Aging test was done at 100℃ for various lengths of time.It was found that some antioxidants are excellent in preventing the oxidative degradation of the irradiated rubber.DAH(2,5-di-tert-amylhydroquinone)+CBP(2,2’-dihydroxy-3,3’-di(-methyl- cyclohexyl)-5,5’-dimethyl diphenyl methane)+P16(tris(2,4-di-tert-butylphenyl)phosphate)in a proportion of(1:0.5:0.5) was found to be the best combination to achieve 100% retention of tensile strength.
