Problems solved by technology

[0002] At present, in the field of rubber, it is very common to use ethylene-propylene rubber as a raw material for various rubber products, but ordinary ethylene-propylene rubber is not outstanding in heat resistance, and products made of ethylene-propylene rubber will be used when necessary In contact with hot environments or products, ordinary ethylene-propylene rubber is likely to affect the life of ethylene-propylene rubber after being heated. Therefore, it is particularly important to solve the problem of insufficient heat resistance of ethylene-propylene rubber made of ordinary materials.

Abstract

The invention provides high temperature-resistant ethylene propylene rubber. The ethylene propylene rubber is composed of the following components by mass: 50-150 parts of ethylene propylene diene monomer, 60-100 parts of carbon black, 5-20 parts of inorganic filler, 3-11 parts of paraffin oil, 5-12 parts of zinc oxide, 1-3 parts of stearic acid and 5-12 parts of dicumyl peroxide. The invention can manufacture ethylene propylene rubber resistant to a high temperature of 160DEG C, and through optimization of the formula, the heat resistance of ethylene propylene rubber is improved, the formulacan be widely applied to engine peripheral rubber parts with high temperature resistance requirement, and solves the problem of insufficient heat resistance of ethylene propylene rubber manufactured from common materials.
