Abstract

The invention discloses a wear-resistant rubber seal and relates to the technical field of seals. The water-resistant rubber seal includes a seal; the seal is made from, by weight, 3.6-4.0% of an antifriction additive, 3.1-3.6% of ZnO, 2.2-2.6% of MgO, 1.8-2.0% of CaCO3, 0.8-1.0% of tetrafluoroethylene micro-powder, 5% of a rubber vulcanizer, 2.6-2.9% of an accelerant, 0.34% of a rubber antiagingagent, 1.6-2.9% of epoxy resin, 3.5-4.3% of molybdenum disulfide, 4.2-4.9% of silane coupling agent, 3.6-4.7% of a resin curing agent, 1.3-2.5% of tetrafluoroethylene micro-powder, 1.3-2.2% of a lubricant, and the balance of natural rubber.

Description

technical field [0001] The invention relates to the technical field of seals, in particular to a friction-resistant rubber seal and a preparation method thereof. Background technique [0002] Rubber seals are a common basic component in sealing devices and are widely used in our daily life and mechanized production. In the process of mechanized production, it is inevitable that the seals will work in harsh environments such as oil and high temperature for a long time, so high-quality seals are bound to be required. Among the existing rubber seals, most seals do not have friction resistance and oil resistance, so there are still great defects and cannot meet the needs of modern production. Contents of the invention [0003] The technical problem to be solved by the present invention is that most seals do not have friction resistance and oil resistance, so there are still great defects, which cannot meet the needs of modern production, overcome the shortcomings of the prior...
