Abstract

The invention discloses a nano bauxite modified chlorosulfonated polyethylene 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 butyl rubber CBK139, 10-15 parts of brominated butyl rubber 1066, 3-5 parts of propanediol sebacate polyester, 3-5 parts of n-butyl methacrylate, 1-2 parts of sodium bicarbonate, 0.5-1 part of sulfur 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 gasket, in particular to a nano-bauxite-modified chlorosulfonated polyethylene rubber gasket 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 polyethylene rub...
