Abstract

The invention relates to a graphene-modified wear-resistant rubber. The graphene-modified wear-resistant rubber comprises, by weight, 48.9 to 56.5% of synthetic rubber, 1.5 to 2.5% of a sulfuration promoter, 8 to 18% of graphene, 25 to 30% of a filling material, 1.5 to 5% of a plasticizer and 0.1 to 3% of an auxiliary agent. According to the invention, graphene is added into the rubber so as to improve strength of the rubber, and since graphene has good lubrication effect, wear resistance of the rubber can be improved; and addition of asbestos fiber and polyimide fiber enables heat resistance of the rubber to be substantially improved.

Description

technical field [0001] The invention relates to the field of rubber materials, in particular to a graphene-modified wear-resistant rubber that improves the wear resistance and tensile strength of rubber. 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. The molecular chains of the rubber can be cross-linked. When the cross-linked rubber is deformed by an external force, it has the ability to recover quickly, and has better physical and mechanical properties and chemical stability. Rubber is the basic raw material of the rubber industry and is widely used in the manufacture of tires, hoses, tapes, cables and other rubber products. Traditional rubber products are not weather-resistant, not durable, have low friction resistance, are easy to crack, and have po...
