Abstract

The invention discloses a chlorosulfonated polyethylene (CSM) rubber/butyl rubber gasket. The gasket comprises the following raw materials in parts by weight: 135-145 parts of CSM2305, 10-15 parts of butyl rubber CBK139, 10-15 parts of butyl rubber BBK232, 3-5 parts of glycerol triacetate, 2-5 parts of epoxidized soybean oil, 2-5 parts of glycerol trioleate, 2-5 parts of magnesium oxide, 1-2 parts of imarcaptoacetate dioctyltin, 5-10 parts of zinc oxide and 5-10 parts of attapulgite. The gasket has the advantages of good high temperature resistance, sealing property, flame retardance and corrosion resistance, can work for a long time in such media as acid, alkali and oil, is small in variation of volume and hardness, is not adhered to the metal surfaces, has small friction coefficient, good wear resistance, flexibility of binding with sealing surfaces and good weathering, aging and ozone aging resistance and is durable in use.

Description

technical field [0001] The invention relates to a gasket, in particular to a chlorosulfonated polyethylene rubber / butyl rubber gasket and a preparation method thereof. Background technique [0002] Gasket is a material used for sealing inside machinery, equipment, pipelines, etc. The gaskets currently used 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 performance. Widely used in defense industry and civilian industry. However, the existing rubber gaskets have 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 high-performance rubber gasket has become the task of top priority. Contents of the invention [0003] The o...
