Abstract

The invention discloses a heat-resistant wear-resistant self-lubricating coating which is prepared from the following components in parts by weight: 100 parts of epoxy resin, 15-20 parts of polyester resin, 45-50 parts of curing agent, 35-40 parts of polytetrafluoroethylene, 9-12 parts of graphite, 25-35 parts of methylbenzene, 1-1.8 parts of silicon carbide, 41-45 parts of glass fibers, 2-4 parts of quartz powder, 1-3 parts of dispersant, 1.1-2.5 parts of flatting agent, 0.2-0.6 part of defoamer and 0.1-0.5 part of silane coupling agent. The coating disclosed by the invention has excellent self-lubricating property and good wear resistance, and can be widely applied to the field having requirements on high-temperature resistance, corrosion resistance, wear resistance and high-insulating performance. The glass fibers are added to improve the mechanical properties of heat generated by friction can be taken away in time, so that the temperature of the film is reduced.

Description

technical field [0001] The invention belongs to the technical field of chemical industry, and in particular relates to a coating, in particular to a heat-resistant and wear-resistant self-lubricating coating. Background technique [0002] Wear and tear is a problem often encountered in high-speed equipment, and equipment will malfunction, be damaged, or even be scrapped. The protection of wear-resistant parts and the repair of worn parts have always been the most concerned issues in the fields of industrial equipment, bearings, machine tools, and engines. The wear-resistant coating plays an important role, and it fully exerts the repair and protection functions in the industrial and military fields. [0003] Wear-resistant coatings are a new type of functional coatings with special functions, which have good wear resistance. For example, anti-wear coatings are coated on glass and lenses, and the glass and lenses will no longer have scratches. The mechanical industry adopt...
