Abstract

The invention discloses a modified compounded rubber seal pad material which is characterized by being prepared from the following raw materials in parts by weight: 65-75 parts of epichlorohydrin rubber (H45), 10-12 parts of fluororubber, 20-24 parts of calcine clay, 12-15 parts of talcum powder, 4-5 parts of glycerol triacetate, 4-6 parts of chlorinated paraffin, 3-5 parts of zinc stearate, 6-8 parts of coumarone, 10-12 parts of nano glass powder, 1-2 parts of rose essential oil, 1-2 parts of an accelerant Na-22, 1-2 parts of an anti-aging agent OD, 1-2 parts of an anti-aging agent NBC, 1-2 parts of sulphur, 2-5 parts of magnesium oxide, 1-2 parts of dibasic lead phosphate, 6-9 parts of N330 carbon black, 12-15 parts of N339 carbon black, and 10-12 parts of modified attapulgite clay. The modified attapulgite clay is added to improve the processing property of the rubber seal pad material; through the application of an environment-friendly compounding ingredient, the toxic and side effects and the environment pollution are reduced; the modified compounded rubber seal pad material is reasonable in formula, simple in process, low in cost, and excellent in oil resistance and corrosion resistance.

Description

technical field [0001] The invention relates to the field of processing rubber composite materials, in particular to a modified composite rubber gasket material 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 th...
