Abstract

The invention discloses an ethylene-propylene-diene monomer and fluororubber compound sealing gasket material which is prepared from the following raw materials in parts by weight: 100-110 parts of ethylene propylene diene monomer (4045), 10-12 parts of fluororubber, 4-6 parts of zinc oxide, 8-10 parts of magnesium oxide, 13-14 parts of tetradecyl methacrylate polymer, 10-12 parts of para-tert-butylphenol formaldehyde resin, 3-4 parts of zinc stearate, 40-45 parts of N660 carbon black, 45-60 parts of spraying carbon black, 0.5-1.5 parts of accelerant CBS (N-Cyclohexy-2-Benzothiazole Sulfonamide), 1-2 parts of accelerant M, 2-3 parts of accelerant DM (dibenzothiazole disulfide) and 10-12 parts of modified attapulgite. According to the ethylene-propylene-diene monomer and fluororubber compound sealing gasket material, by adding the modified attapulgite, the process property of a rubber material is improved; by using an environment-friendly compounding agent, the toxic and side effects and the pollution to the environment are reduced. The ethylene-propylene-diene monomer and fluororubber compound sealing gasket material is reasonable in formula, simple in process and low in cost and has better oil resistance and sealing property.

Description

technical field [0001] The invention relates to the field of processing rubber composite materials, in particular to an EPDM fluorine rubber composite 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...
