Abstract

The invention discloses a butadiene-acrylonitrile rubber and fluororubber composite sealing gasket material. The butadiene-acrylonitrile rubber and fluororubber composite sealing gasket material is characterized in that the butadiene-acrylonitrile rubber and fluororubber composite sealing gasket material is prepared from the following raw materials in parts by weight: 80-90 parts of butadiene-acrylonitrile rubber, 20-24 parts of fluororubber, 1-2 parts of tetrabenzylthiuramdisulfide, 12-14 parts of silicon dioxide, 2-3 parts of zinc oxide, 3-4 parts of calcium ferrite, 1-2 parts of zinc phosphate, 10-12 parts of barium chromate, 1-2 parts of 2-mercaptobenzimidazole, 1-2 parts of accelerator CZ, 1-2 parts of accelerator M, 30-34 parts of N330 carbon black, 24-28 pars of N550 carbon black, 8-10 parts of epoxy linseed oil and 10-12 parts of modified attapulgite. The processing property of the rubber material is improved due to adding of the modified attapulgite; the environment-friendly accessory ingredients are used to reduce toxic and side effects and environmental pollution; the butadiene-acrylonitrile rubber and fluororubber composite sealing gasket material has reasonable formula, simple process, low cost, and good oil resistance, corrosion resistance and ageing resistance.

Description

technical field [0001] The invention relates to the field of processing rubber composite materials, in particular to a nitrile rubber fluorine rubber mixing 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 prio...
