A high-temperature-sulfuration rubber compound

Abstract

A high-temperature-sulfuration rubber compound is disclosed. The rubber compound comprises following raw materials by weight: 80 parts of methyl vinyl silicone rubber, 20 parts of acrylate rubber, 0.5 part of an internal releasing agent, 5 parts of hydroxyl silicone oil, 50 parts of carbon black, 5 parts of a compatibilizer, 1.4 parts of dicumyl peroxide and 0.2 part of 2,5-dimethyl-2,5-di(tert-butylperoxy)hexane. According to the rubber compound, silicon rubber and acrylate rubber are combined so that the properties of the silicon rubber and the acrylate rubber are complementary to each other so as to obtain a high-temperature-sulfuration rubber material and a product which are resistant to high temperature and resistant to hot oil, thus meeting requirements of the automobile market, the electromechanical market, and the like which are booming at present.

Description

[0001] technical field [0002] The invention relates to a mixed rubber, in particular to a high-temperature vulcanized mixed rubber. [0003] Background technique [0004] In recent years, with the advancement of automobile technology, the engine has been continuously miniaturized and increased in power. When the automobile is running, the engine generates a lot of heat. The existing oil-resistant products mainly composed of nitrile rubber can no longer meet the requirements of automobiles. There is an urgent need to develop a rubber product with high oil resistance and long-term high temperature resistance up to about 200°C. The same is true in the markets of engines, air compressors, vacuum machines, motorcycles, etc. The models are getting smaller and smaller, the power is getting bigger and bigger, the heat generated is getting more and more, and the machine temperature is getting higher and higher. The working environment of rubber parts It's getting harsher. [000...
