Abstract

The invention discloses a self-lubricating wear-resistant coating resistant to impact and high-temperature ablation and a preparation method thereof. The coating consists of a binder, a lubricating wear-resistant agent, aids and a mixed solvent, wherein polyetheretherketone is adopted as the binder, polytetrafluoroethylene, molybdenum disulfide and graphite are adopted as the lubricating wear-resistant agent, a melamine and cyanurnate complex, lead oxide and rare earth oxide are adopted as the aids, the mixed solvent is a mixture of distilled water, ethanol and butanol, and a coating prepared from the paint provided by the invention is friendly to environment, ultrahigh in load bearing and good in adaptability to a lubricating oil medium, has the good performances of impact resistance, high-temperature ablation resistance, long life and the like as well as an integrated performance of excellent functions such as high bonding strength, good flexibility, resistance to chemical erosion and medium resistance, and can be applied to a high-bearing joint bearing, a gear / shaft and other transmission system parts as the long-life self-lubricating wear-resistant coating resistant to medium, impact and high-temperature ablation.

Description

technical field [0001] The invention belongs to the field of coating compositions, and in particular relates to an impact-resistant, high-temperature, ablation-resistant, self-lubricating and wear-resistant coating, and also relates to a preparation method of the impact-resistant, high-temperature, ablation-resistant, self-lubricating and wear-resistant coating. Background technique [0002] Heavy equipment, automobiles, motorcycles, machinery, etc. are under dry friction and long-term oil shortage / poor oil lubrication, and joint bearings, cylinder pistons, gears / shaft transmission systems continue to operate, resulting in an increase in the surface temperature of the components, sintering and straining the components, so that Key components fail, which shortens the working life of the equipment and greatly increases the energy consumption and cost of the equipment. If a layer of environmentally friendly high temperature resistant self-lubricating and wear-resistant coating ...
