Abstract

The invention discloses an oil resistant sealing member rubber material prepared from equal-proportioned and mixed components of an A rubber material and a B rubber material. The A rubber material comprises components of, by weight: 85 to 95 parts of butyronitrile rubber N41, 0.3 to 0.5 parts of sulfur, 4 to 6 parts of zinc oxide, 3 to 4 parts of stearic acid, 1 to 2 parts of an anti-aging agent RD, 1 to 2 parts of an anti-aging agent 4010NA, 3 to 4 parts of micro-crystalline wax, 22 to 25 parts of fast extruding furnace carbon black N660, 62 to 65 parts of high abrasion furnace black N330, 18 to 22 parts of DOP, 25 to 35 parts of calcium sulfate, 3 to 4 parts of a promoter DM, 1 to 2 parts of a promoter TMTD, and 1 to 2 parts of a promoter TETD. The B rubber material comprises components of, by weight: 82 to 87 parts of unitary homo-polymerized chlorohydrin rubber, 12 to 18 parts of copolymerized chlorohydrin rubber, 1 to 2 parts of zinc stearate, 1 to 3 parts of an anti-aging agent RD, 0.4 to 0.6 parts of Gum Easy T-78, 1 to 2 parts of clariant wax, 45 to 55 parts of fast extruding furnace carbon black, 10 to 14 parts of diatomite, 5 to 8 parts of DOP, 4 to 6 parts of dilead tetraoxide 0.4 to 0.6 parts of sulfur, and 1 to 2 parts of a promoter Na-22. Oil resistant sealing members (oil cylinder sealing members) produced from the rubber material provided by the invention has good oil resistance, heat resistance, air-tightness, flame retardance, tearing resistance, and low cost.

Description

technical field [0001] The invention relates to the field of processing rubber composite materials, in particular to a rubber material for an oil-resistant seal and a preparation method thereof. Background technique [0002] Oil-resistant seals have special requirements for the formulation of rubber materials, and the products are required to have high oil resistance, high heat resistance, and high air tightness. The usual 41 nitrile rubber formula is not as oil-resistant, heat-resistant, and air-tight as hydrogenated nitrile rubber and chlorohydrin rubber, but hydrogenated nitrile rubber and chlorohydrin rubber are expensive and costly; therefore, oil-resistant seals (cylinder gaskets) The improvement of oil resistance, heat resistance, air tightness and cost saving must be researched and practiced. For this reason, the rubber formula has been researched and invented. Contents of the invention [0003] The invention provides a rubber material for an oil-resistant seal an...
