Abstract

The invention discloses a sealing gasket material prepared by mixing three types of rubber. The sealing gasket material is characterized by being prepared from the following raw materials in parts by weight: 20-25 parts of silicone rubber, 30-35 parts of epichlorohydrin rubber (H45), 20-24 parts of butadiene-acrylonitrile rubber, 24-28 parts of precipitated silica, 3-4 parts of diphenyl silanediol, 3-4 parts of ferric oxide, 2-3 parts of dicumyl peroxide, 1.5-2.5 parts of eleostearic acid, 2-5 parts of zinc oxide, 1-2 parts of butadiene, 10-15 parts of butyl rubber (BBK232), 3-5 parts of triethyl citrate, 3-5 parts of tung oil, 18-23 parts of N220 carbon black, 25-30 parts of N339 carbon black and 10-12 parts of modified attapulgite. By adding the modified attapulgite, the process performance of a rubber material is improved. By using an environment-friendly ingredient, the toxic and side effects and the environmental pollution are reduced. The sealing gasket material is high in temperature change resistance, high in oil resistance, high in corrosion resistance, high in ageing resistance and good in sealing performance.

Description

technical field [0001] The invention relates to the field of processing rubber composite materials, in particular to a gasket material prepared by mixing three types of rubber 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. ...
