The invention discloses a high oil-resistant sealing element rubber material, which is mixed by A and B rubber compounds in equal proportion. The two rubber compounds have the following material components by weight: A rubber compound: 85-95 of nitrile-butadiene rubber, 0.3-0.5 of sulphur, 4-6 of zinc oxide, 3-4 of eleaostearic acid, 1-2 of an anti-oxidant 2, 5-ditert-butylhydroquinone-DTBHQ, 1-2 of an antiager RD, 1-2 of an antiager 4010NA, 3-4 of paraffin, 22-25 of fast extruded carbon black N660, 62-65 of high abrasion carbon black, 18-22 of dioctyl-phthalate, 25-35 of calcium carbonate, 3-4 of an accelerator DM, 1-2 of an accelerator TMTD, 1-2 of an accelerator TETD; B rubber compound: 82-87 of monohomopolymerized epichlorohydrin rubber, 12-18 of copolymerized epichlorohydrin rubber, 1-2 of zinc stearate, 1-3 of an antiager RD, 0.4-0.6 of Gum easy T-78, 1-2 of rhein wax, 45-55 of fast extruded carbon black, 10-14 of diatomite, 5-8 of dioctyl-phthalate, 4-6 of lead tetraoxide, 0.4-0.6 of sulphur, and 1-2 of an accelerator Na-22. The rubber material can be used to produce oil-resistant sealing elements (oil cylinder sealing gaskets) with the advantages of oil resistance, thermoresistance, air impermeability, flame retardation and tear resistance and low cost.
