High-temperature-resistant low-pollution low-odor automobile door cushion pad and preparation method thereof

The invention relates to a high-temperature-resistant low-pollution low-odor automobile door cushion and a preparation method thereof.The automobile door cushion is prepared from, by mass, 100-200 parts of ethylene propylene diene monomer, 3-12 parts of zinc oxide, 1-3 parts of a silane coupling agent, 20-100 parts of hydrogenated paraffin oil, 80-150 parts of carbon black, 5-25 parts of white carbon black, 2-5 parts of a vulcanizing agent 2, 5-dimethyl-2, 3, 4-trimethyl-1, 3-pentanediol monoisobutyrate, 1-3 parts of an antioxidant, 1-3 parts of an antioxidant and 1-3 parts of a lubricant. 2 to 6 parts of 1, 5-bis (tert-butyl peroxide) hexane and 0.5 to 2 parts of peroxide scorch retarder. The invention mainly focuses on reducing the pollution of the synthetic rubber for manufacturing the automobile door cushion pad, adopts a vulcanizing agent 2, 5-dimethyl-2, 5-peroxide vulcanization system, has simple material components, does not generate pollutants in vulcanization reaction, meets the requirement of long-
