Abstract

The invention discloses a chlorosulfonated polyethylene rubber / chloroprene rubber gasket. The gasket comprises the following raw materials in parts by weight: 135-145 parts of chlorosulfonated polyethylene rubber CSM2305, 10-15 parts of chloroprene rubber S40V, 10-15 parts of SG-2 type PVC (polyvinyl chloride) resins, 2-4 parts of propanediol sebacate polyester, 3-5 parts of n-butyl methacrylate, 1-2 parts of sodium bicarbonate, 0.5-1 part of sulfur, 1-2 parts of calcium stearate and the like. The gasket has the beneficial effects that the gasket has good high temperature resistance, sealability, flame retardance and corrosion resistance and can work in such media as acid, alkali and oil for a long time; the volume and hardness of the gasket are small in variation; the gasket does not adhere to metal surfaces; and the gasket has small friction coefficient and good abrasion resistance and has the advantages of softness of bonding with sealing surfaces, good weathering aging and ozone aging resistance, durability and the like.

Description

Technical field [0001] The invention relates to a sealing gasket, in particular to a chlorosulfonated polyethylene rubber / chloroprene rubber sealing gasket and a preparation method thereof. Background technique [0002] Sealing gasket is a kind of material used for sealing inside machinery, equipment, pipelines, etc. The gaskets currently in use are mostly rubber gaskets, which are characterized by high temperature resistance, ozone resistance, natural aging resistance, vacuum resistance, fuel oil resistance, lubricating oil resistance, strong oxidant resistance, chemical resistance and good electrical insulation properties. It is widely used in national defense industry and civil industry. However, the existing rubber gaskets have disadvantages such as unsatisfactory sealing effect, poor wear resistance, and low strength, which are far from meeting practical requirements. Therefore, the development of a high-performance rubber gasket has become a top priority. Summary of the ...
