Preparation method of cyanate ester based wear-resistant self-lubricating swash plate

Abstract

The invention discloses a preparation method of a cyanate ester based wear-resistant self-lubricating swash plate. The preparation method comprises following steps: preparation of a promoter; preparation of an oxidized graphene / cyanate ester-epoxy resin composite material; preparation of a wear-resistant self-lubricating coating layer; spraying; and curing; wherein the oxidized graphene / cyanate ester-epoxy resin composite material is dissolved in acetone so as to obtain a composite material acetone solution with a mass concentration of 40%; 30 mass parts of a solid lubricating agent is added into 100 mass parts of the composite material acetone solution for uniform mixing so as to obtain a wear-resistant coating layer solution. The wear-resistant coating is reasonable in composition, and excellent in heat resistance and bonding performance, so that the swash plate prepared based on the wear-resistant coating possesses excellent wear resistance, wet state friction performance and oil state friction state are both much better than that of conventional resin swash plates, and the requirements of automobile air-conditioning compressor can be satisfied.

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 wear-resistant self-lubricating swash plate based on cyanate ester. 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-wa...

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

Existing swash plates have certain deficiencies in self-lubrication, heat resistance, wear resistance and adhesion
