Abstract

The invention discloses a rubber gasket. The rubber gasket comprises, by weight, 10-20 parts of polysulfide rubber, 50-65 parts of fluororubber, 10-20 parts of polyamide, 2-6 parts of chlorosulfonated polyethylene, 1-2 parts of zinc sulfate, 0.5-2 parts of glass powder, 1-5 parts of terpene resin, 1-1.5 parts of anti-aging agent, 0.5-1.5 parts of vulcanizing agent, 10-20 parts of ethyl acetate and 10-15 parts of cyclohexanone. The rubber gasket is soft in texture, good in elasticity and high in chemical corrosion resistance.

Description

technical field [0001] The invention relates to the technical field of rubber, in particular to a rubber gasket. Background technique [0002] 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 heavy and emerging industries such as mining, transportation, construction, machinery, and electronics. Various rubber-made production equipment or rubber parts. [0003] Rubber pads include transparent rubber pads, EVA rubber pads, EVA pads, round pads, semi-circular transparent pads, silicone pads, etc. The current rubber mat has a hard texture and is easy to break when used at room temperature; in addition, during the preparation process of the rubber mat, the mixing time is long, which damages the physical and mechanical properties of the rubber. Contents of the invention [0004] The object of the present ...
