Abstract

The invention discloses an oil resistant rubber ring material composition and a preparation method of an oil resistant rubber ring, wherein the composition is prepared from nitrile rubber, fluorinated silicone rubber, acrylate rubber, potassium permanganate, calcium nitrate, sulphur, zinc chloride and magnesium chloride; relative to 100 parts by weight of the nitrile rubber, the content of the fluorinated silicone rubber is 10 to 30 parts by weight, the content of the acrylate rubber is 20 to 50 parts by weight, the content of the potassium permanganate is 3 to 15 parts by weight, the content of the calcium nitrate is 5 to 20 parts by weight, the content of the sulphur is 1 to 5 parts by weight, the content of the zinc chloride is 3 to 10 parts by weight, and the content of the magnesium chloride is 3 to 10 parts by weight. Through the design, the effects of realizing effective oil resistance and greatly improving the usability under the environment with high grease are achieved.

Description

technical field [0001] The invention relates to the field of production and preparation of rubber ring materials, in particular to an oil-resistant rubber ring material composition and a preparation method for an oil-resistant rubber ring. Background technique [0002] Rubber rings are widely used in the automotive field. For example, rubber rings are used in automobile clutches and other components, but rubber rings are often not resistant to oil, and are prone to aging and other phenomena in long-term oily environments, which greatly affect The performance of the product will increase the cost of replacement and use. [0003] Therefore, it is an urgent problem to be solved in the present invention to provide an oil-resistant rubber ring material composition and a preparation method of an oil-resistant rubber ring that can effectively resist oil and greatly improve the performance in an environment with high oil content. Contents of the invention [0004] In view of the ...
