Abstract

Automotive high-temperature-resistant rubber is prepared from, by weight, 80-90 parts of natural rubber, 30-50 parts of silicone rubber, 25-35 parts of butadiene rubber, 10-25 parts of butadiene-acrylonitrile rubber, 20-35 parts of fluororubber, 20-30 parts of ethylene propylene diene monomer, 5-15 parts of aromatic oil, 2-5 parts of stearic acid, 5-6 parts of coupling agent, 4-10 parts of stearic acid, 2-7 parts of zinc oxide, 1-5 parts of nanosilicon dioxide, 1-5 parts of anti-ageing agent, 0.5-5 parts of accelerator, 0.5-3 parts of high-aluminum powder, 10-15 parts of highly-high-temperature-resistant carbon black, 10-15 parts of silica powder, 2-3 parts of sulphur, 0.8-1.5 parts of accelerant, 3-5 parts of zinc oxide, 3-5 parts of anti-ageing agent and 5-10 parts of silane coupling agent. Through the prepared high-temperature-resistant rubber, a quite good high-temperature-resistant effect can be achieved, and meanwhile the rubber has quite good high temperature resistance and heat resistance.

Description

technical field [0001] The invention relates to the field of high-temperature-resistant rubber production, in particular to a novel high-efficiency high-temperature-resistant rubber for vehicles and a production method. Background technique [0002] The rubber industry is one of the important basic industries of the national economy. It not only provides daily and medical light industrial rubber products that are indispensable for people’s daily life, but also provides various rubber production equipment or rubber parts for mining, transportation, construction, machinery, electronics and other heavy industries and emerging industries. It can be seen that the rubber industry has a wide variety of products, and the backward industry is very broad. [0003] In the prior art, natural rubber is usually used to manufacture rubber for automobiles. Due to the chemical structure of natural rubber itself, its oxidation resistance and corrosion resistance are poor, thereby affecting t...
