Abstract

The invention discloses a high-strength fluorine rubber gasket material. The high-strength fluorine rubber gasket material is characterized by being prepared from the following raw materials in parts by weight: 75-80 parts of fluororubber, 20-24 parts of carbon black, 2-3 parts of 2.5-dimethyl-2.5 bi(tertiary butyl peroxyl) hexane, 4-5 parts of triallyl isocyanurate, 10-12 parts of diisobutyl phthalate, 2-3 parts of aluminium stearate, 1-2 parts of sulphur, 2-3 parts of zinc oxide, 3-4 parts of vaseline, 14-18 parts of butyl rubber (BBK232), 3-5 parts of glycerinum triacetate, 20-25 parts of bauxite powder, 10-15 parts of carbon black N339, 1-2 parts of a titanate coupling agent TMC-TTS, 0.8-1.2 parts of an accelerant Na-22, and 10-12 parts of modified attapulgite. The modified attapulgite is added in the high-strength fluorine rubber gasket material, so that the processing property of a sizing material is improved. The high-strength fluorine rubber gasket material has the advantages of high strength, good oil resistance, pressure resistance and sealing performance, simple process and low cost.

Description

technical field [0001] The invention relates to the field of processing rubber composite materials, in particular to a high-strength fluorine rubber sealing 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. Co...
