Description

technical field [0001] The invention relates to the field of wear-resistant rubber, in particular to a novel wear-resistant rubber and a preparation method thereof. Background technique [0002] Rubber is a highly elastic polymer material with reversible deformation. It is elastic at room temperature, can produce large deformation under a small external force, and can return to its original shape after the external force is removed. Rubber is a completely amorphous polymer with a low glass transition temperature and often a large molecular weight, greater than hundreds of thousands. 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.

Problems solved by technology

In the prior art, natural rubber is usually used to manufacture new wear-resistant rubber. Due to the chemical structure of natural rubber itself, its oxidation resistance and corrosion resistance are poor, thus affecting the physical and mechanical properties and service life of automotive rubber products.
