Abstract

The invention discloses wear-resistant rubber for automobiles, which is composed of following raw materials, by weight, 35-38 parts of chloroprene rubber, 30-40 parts of nitrile butadiene rubber, 10-15 parts of isoprene rubber, 5-8 parts of polyvinyl chloride, 20-25 parts of carbon black, 1-3 parts of magnesium stearate, 2-4 parts of stearic acid, 3-5 parts of pine tar, 1-3 parts of zinc oxide, 0.5-1 part of paraffin and 1-3 parts of a surface modifier. The wear-resistant rubber is good in physical mechanical performance, is wear-resistant, anti-aging, high-temperature- and low-temperature-resistant and is long in service life.

Description

technical field [0001] The invention belongs to the technical field of rubber, in particular to a wear-resistant rubber for automobiles. Background technique [0002] Automotive rubber products are an indispensable and important component of auto parts. Calculated according to different types of cars, there are about 100-200 kinds of rubber products to be installed on each car, and about 200-500 kinds of rubber parts to be used. According to statistics, the automobile industry accounts for more than 70% of the world's annual consumption of raw rubber, of which tires account for 60%, and automotive rubber parts account for 40%. With the modernization of automotive technology, the requirements for automotive rubber products are becoming increasingly stringent. And demanding, not only require rubber materials with various special properties to meet the new technical requirements of automobiles, but also require rubber materials to have higher physical and mechanical properties...
