Abstract

The invention provides an oil resistant rubber material. The oil resistant rubber material comprises the following components in parts by weight: 60-70 parts of butadiene-acrylonitrile rubber, 25-35 parts of fluororubber, 5-10 parts of dioctyl tin maleate, 2-3 parts of glass fibers, 1-2 parts of stearic acid, 0.5-0.8 part of light calcium carbonate, 3-5 parts of magnesium dimethacrylate, 2-3 parts of drying oil alkyd resin, 1-2 parts of paraffin, 3-5 parts of dilauryl thiodipropionate, 1-2 parts of diacetyl peroxide, 0.8-1.2 parts of zinc oxide, 8-10 parts of aluminium oxide, 6-8 parts of white carbon black, 0.8-1.5 parts of anti-aging agent and 1-3 parts of sulfur. The invention also provides a preparation method of the oil resistant rubber material. The oil resistant rubber material has good sealability, high temperature resistance and oil resistance and is suitable for sealing automobile gearboxes.

Description

technical field [0001] The invention belongs to the technical field of polymers, and in particular relates to an oil-resistant rubber material. Background technique [0002] Automotive oil seals are precision rubber components with the most complex structure, the highest technical content, and the most widely used rotary seals. Its quality not only affects the sealing performance and service life of the car, but more importantly, affects the driving and safety of the car. The main function of the gearbox oil seal is to prevent lubricating oil from leaking out from the fitting gap between the hole and the shaft, and to prevent dust and impurities from entering the inside. In order to ensure its tightness and working reliability under any working conditions of the car, the oil seal needs to be able to withstand the working conditions of high speed, medium resistance and high and low temperature resistance. Existing rubber materials have poor oil resistance. Contents of the...
