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 ...
