Abstract

The invention discloses a rubber sealing ring composition. The a rubber sealing ring composition is prepared from nitrile rubber, fluororubber, a promoter, high styrene resin, powdered steatile, zinc monomethacrylate, stearic acid, wear resistant carbon black, calcium sulfate, dibutyl phthalate, sulphur, Gum easy, an antiager RD, Antilux wax and 4, 4'-dithiodimorpholine according to a certain weight part ratio. The rubber sealing ring composition has characteristics of wear resistance, heat resistance, shock resistance, fatigue resistance, high temperature resistance and good gas tightness.

Description

Technical field [0001] The invention relates to the field of rubber preparation, in particular to a rubber sealing ring composition. Background technique [0002] Existing rubber sealing rings are required to have higher hardness and lower compression permanent deformation. At the same time, according to different usage requirements, the sealing rings also have related requirements in terms of oil resistance, heat resistance and air sealing. Summary of the invention [0003] In view of the above problems, the present invention provides a rubber sealing ring composition, which solves the problem that commonly used rubber sealing rings cannot simultaneously have high oil resistance, high heat resistance, and shock and wear resistance. [0004] In order to solve the above problems, the technical solution adopted by the present invention is: a rubber sealing ring composition, the raw materials of which comprise by weight: 40-55 parts of nitrile rubber, 15-25 parts of fluorine rubber, 2-...
