Problems solved by technology

[0006] The existing base resin used for swash plate preparation is generally polyimide or polyamide-imide, which can improve the self-lubricating performance of the swash plate to a certain extent, but the friction of the wear-resistant coating thus formed, In particular, the dry friction performance and adhesion need to be improved; there are also some reports on the use of polyetherketone, polyethersulfone or polyethersulfoneketone materials for swashplates, such materials have certain heat resistance, However, the adhesion is poor and the compatibility with other materials is poor; and the existing base resins cannot be dissolved in conventional solvents such as acetone, and all need toxic and environmentally friendly solvents to dissolve, which is harmful to the social environment. The curing process of the basic resin is very harsh, and it needs to exceed 300°C, and the time is several hours, which not only increases the difficulty of preparation, but also increases the energy consumption of the society

Abstract

The invention discloses a preparation method of a wear-resistant and flame-retardant swash plate. The prepared swash plate comprises a base plate and a wear-resistant coating, wherein the wear-resistant coating comprises base resin, silicon-containing phosphate, PTFE (polytetrafluoroethylene) particles, graphite fluoride and composite filler. The wear-resistant paint disclosed by the invention is reasonable in composition and has excellent heat resistance and adhesion. The swash plate based on the wear-resistant paint has excellent wear resistance and flame retardance, has dry state or oil state friction property far better than that of swash plates prepared from the existing resin, and can meet the requirements of auto air conditioning compressors.

Description

technical field [0001] The invention relates to the preparation of a swash plate of an automobile air-conditioning compressor, in particular to a preparation method of a swash plate with wear-resistant and flame-retardant properties. Background technique [0002] Automobile air-conditioning compressor is the key component of automobile air-conditioning system, among them, the swash-plate air-conditioning compressor has the advantages of simple structure, reliable adjustment, good balance performance of the machine, and high speed, etc. The most common compressor accounts for about 80% of the passenger car market, and it has a tendency to expand further. [0003] In the swash plate air conditioner compressor, the swash plate rotates at the same speed as the main shaft passing through the swash plate, and the swash plate drives the piston to reciprocate through the connection between the sliding shoe and the piston, and then completes the gas compression through the one-way co...
