Description

Technical field [0001] The invention belongs to the technical field of rubber seal processing and manufacturing, and specifically relates to a wear-resistant rubber seal. Background technique [0002] Nitrile rubber is known for its excellent oil resistance and low price, so it is widely used in the rubber industry, especially in seals. Good elasticity and large friction factor are inherent characteristics of rubber materials. Seals made of rubber materials are used in a dynamic environment, and friction problems often affect the efficiency and service life of the seal. For this reason, strive to reduce the frictional influence of rubber dynamic seals. Summary of the invention [0003] The purpose of the present invention is to provide a wear-resistant rubber seal against the existing problems. [0004] The present invention is realized through the following technical solutions: [0005] A wear-resistant rubber seal made of the following parts by weight: [0006] 60~65 parts of liq...
