Abstract

The invention discloses a nanometer argil modified chlorosulfonated polyethylene rubber sealing gasket. The sealing gasket comprises the following raw materials, by weight, 135-145 parts of chlorosulfonated polyethylene rubber CSM2305, 10-15 parts of chloroprene rubber CR121, 10-15 parts of butyl rubber CBK139, 3-5 parts of m-phthalate, 3-5 parts of phthalic polyester, 2-5 parts of trioctyl trimellitate and 1-2 parts of sulfur. The sealing gasket has the advantages of good high-temperature resistance, good sealing performance, good flame retardation, good corrosion resistance, realization of long-term working in mediums comprising acids, alkalis, oils and the like, small volume and hardness changes, no adhesion on the metal surface, small friction coefficient, good abrasion resistance, combination flexibility with the sealing surface, good weather ageing and ozone ageing resistances, durability and the like.

Description

technical field [0001] The invention relates to a sealing pad, in particular to a nano-clay modified chlorosulfonated polyethylene rubber sealing pad and a preparation method thereof. Background technique [0002] Chlorosulfonated polyethylene rubber gasket is a material used for sealing inside machinery, equipment, pipelines, etc. Chlorosulfonated polyethylene rubber gasket has unique aging resistance, heat resistance, flame retardancy, especially weather resistance, ozone resistance and chemical corrosion resistance, which are unmatched by any other rubber. Therefore, it can better meet the needs of various fields. Harsh requirements, widely used in defense industry and civilian industry. However, the existing chlorosulfonated polyethylene rubber gasket has defects such as unsatisfactory sealing effect, poor wear resistance and low strength, which are far from meeting the actual requirements. Therefore researching and developing a kind of novel chlorosulfonated polyethyl...
