Abstract

The invention discloses novel abrasion resistant rubber. The rubber is prepared from, by weight, 80-100 parts of polyurethane rubber, 40-60 parts of ethylene propylene diene monomer, 40-50 parts of nitrile rubber, 20-30 parts of brominated butene rubber, 10-20 parts of expanded perlite powder, 3-5 parts of sulfur, 1-5 parts of softener, 3-5 parts of nanometer zinc oxide, 6-10 parts of allene siloxane, 20-30 parts of activated magnesium oxide, 10-20 parts of carboxylated graphene and 6-10 parts of ethyl carbamate, wherein the softener is a mixture of paraffin oil and rosin, and the mass ratio of the paraffin oil to the rosin is (1.9-2.3):1. The novel abrasion resistant rubber has the advantages that by means of the synergistic effect among the raw materials, compared with ordinary rubber, the prepared abrasion resistant rubber has the excellent abrasion resistant property and is high in mechanical strength, good in sound isolation effect and the like.

Description

technical field [0001] The invention belongs to the technical field of rubber production, and in particular relates to a novel wear-resistant rubber. Background technique [0002] Rubber 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. [0003] 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 to people's daily life, but also provides various rubber production equipment or rubber parts for heavy industries such as excavation, transportation, construction, machinery, electronics, and emerging industries. The wear res...
