The rubber material comprises the following raw materials in parts by weight: 50 to 70 parts of hydrogenated nitrile rubber, 30 to 50 parts of fluororubber, 10 to 20 parts of polytetrafluoroethylene, 40 to 60 parts of composite filling material, 10 to 20 parts of microencapsulated red phosphorus, 5 to 15 parts of zinc borate, 20 to 30 parts of ammonium polyphosphate, 15 to 25 parts of acetyl trioctyl citrate, 1 to 3 parts of benzoyl peroxide, 0.2 to 0.4 part of dibutyl tin dilaurate, 0.3 to 0.5 part of promoter D, 0.1 to 0.2 part of promoter ZDC, 1 to 2 parts of Ca / Zn composite stabilizer, 1 to 2 parts of dibutyl tin dichloride, 1 to 2 parts of rare earth stabilizer, 0.2 to 0.4 part of anti-aging agent MB, 0.2 to 0.4 part of anti-aging agent 445, and 2 to 4 parts of montan wax; wherein the composite filling material comprises aerosil, modified molybdenum disulfide, modified graphite, and modified silicon carbide.

Description

technical field [0001] The invention relates to the technical field of rubber, in particular to a high-temperature-resistant and abrasion-resistant rubber material for oil seals. Background technique [0002] The oil seal is a mechanical component used to seal oil, which isolates the parts that need to be lubricated from the output parts in the transmission parts, so that the lubricating oil will not leak. The material used as an oil seal needs to have good sealing performance, mechanical properties, oil resistance and wear resistance. Due to friction, it needs to have good heat resistance. However, with the rapid development of industrial production, the aging resistance of existing oil seals, Wear resistance and high temperature resistance can no longer meet people's use requirements, and a new oil seal with good corrosion resistance, wear resistance and high temperature resistance needs to be proposed. Contents of the invention [0003] Based on the technical problems ...

Problems solved by technology

The material used as an oil seal needs to have good sealing performance, mechanical properties, oil resistance and wear resistance. Due to friction, it needs to have good heat resistance. However, with the rapid development of industrial production, the aging resistance of existing oil seals, Abrasion resistance and high temperature resistance can no longer meet people's use requirements. It is necessary to propose a new oil seal with good corrosion resistance, wear resistance and high temperature resistance.
