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 method for preparing a swash plate based on bismaleimide. The method comprises the steps of preparing a bismaleimide / diallyl bisphenol A copolymer, preparing a wear-resistant coating, spraying and curing, wherein the wear-resistant coating is prepared from the following ingredients in parts by mass: 40-60 parts of bismaleimide / diallyl bisphenol A copolymer, 20-50 parts of PTFE (Polytetrafluoroethylene), 10-30 parts of molybdenum disulfide, 5-10 parts of graphite fluoride and 1-10 parts of reinforcing material nano aluminum oxide. According to the method for preparing the swash plate based on bismaleimide, disclosed by the invention, the wear-resistant coating is reasonable in composition and excellent in heat resistance and adhesion, thus the swash plate based on the wear-resistant coating has excellent wear resistance, has the friction performance, which is far superior to that of the existing swash plates prepared from resin regardless of whether the swash plate is in a dry state or oil state, and can meet the needs of an automotive air conditioner compressor.

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 bismaleimide-based swash plate. 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 control of suction and exhaust. ;...
