Embodiment 1

[0031] Self-lubricating wear-resistant coating coating is composed of 40% polynaphthalene polyether ketone (PPEK), 40% polyether sulfone ketone (PPESK) and 5% polytetrafluoroethylene (PTFE), 5% perfluoroethylene Propylene tetrafluoroethylene hexafluoropropylene (FEP) and 4% tungsten disulfide (WS 2 ), 4% molybdenum disulfide (MoS 2 ) and 1% aluminum oxide (Al 2 o 3 ), 1% titanium dioxide (TiO 2 ) composition, using solvent N-methylpyrrolidone as a solvent to configure the coating to be sprayed on the swash plate metal substrate 6. Dry and sinter in an oven, and then turn and grind to form a coating 5 with a thickness of 0.02-0.04mm.

Embodiment 2

[0033] The self-lubricating wear-resistant coating is composed of 38% polynaphthalene polyether ketone (PPEK), 38% polyether sulfone ketone (PPESK) and 6% polytetrafluoroethylene (PTFE), 6% perfluoroethylene Propylene tetrafluoroethylene hexafluoropropylene (FEP) and 5% tungsten disulfide (WS 2 ), 5% molybdenum disulfide (MoS 2 ) and 1% silicon carbide (SiC), 1% aluminum oxide (Al 2 o 3 ) composition, using solvent N-methylpyrrolidone as a solvent to configure the coating to be sprayed on the swash plate metal substrate 6. Dry and sinter in an oven, and then turn and grind to form a coating 5 with a thickness of 0.02-0.04mm.

Embodiment 3

[0035] The self-lubricating wear-resistant coating paint is composed of 40% polynaphthalene polyether ketone (PPEK), 40% polynaphthalene polyether sulfone (PPES) and 5% polyvinylidene fluoride (PVDF), 5% perfluoroethylene propylene Tetrafluoroethylene hexafluoropropylene (FEP) and 4% tungsten disulfide (WS 2 ), 4% molybdenum disulfide (MoS 2 ) and 1% silicon carbide (SiC), 1% titanium dioxide (TiO 2 ) composition, using solvent N-methylpyrrolidone as a solvent to configure the coating to be sprayed on the swash plate metal substrate 6. Dry and sinter in an oven, and then turn and grind to form a coating 5 with a thickness of 0.02-0.04mm.

Abstract

The invention relates to a self-lubricating wear-resistant coating swash plate, which consists of a metallic matrix and a self-lubricating wear-resistant coating, wherein annular planes on two sides of the metallic matrix are coated with the self-lubricating wear-resistant coating, and the components of the self-lubricating wear-resistant coating comprise a main material of high molecular materials, fluoroplastics, solid lubricants and inorganic matters. A process for producing the self-lubricating wear-resistant coating swash plate comprises that: the self-lubricating wear-resistant coating is coated on the swash plate after being prepared into a liquid coating, and a method for preparing the liquid coating comprises the steps of using a solvent of N-methyl pyrrolidone or dimethyl acetamide to dissolve the main material of the high molecular materials first, and then adding the fluoroplastics, the solid lubricants and the inorganic matters into the mixture to perform sufficient stirring and dispersion so as to prepare the liquid coating with certain solid content. The swash plate has the advantages of good self-lubricating and wear-resistant performance, simple production process and low production cost, and does not contain metallic lead which is harmful to human bodies and the environment.

Description

technical field [0001] The invention relates to a swash plate of a swash plate type automobile air-conditioning compressor and a production process. In particular, it relates to a swash plate for improving the lubricating and antifriction properties between the swash plate and sliding shoes in the automobile air-conditioning compressor. The technical fields related to the present invention include swash plate compressors, swash plate sliding layers with composite structures, polymer self-lubricating materials and the like. technical background [0002] The working principle of the swash plate type automotive air-conditioning compressor is to drive the reciprocating motion of the compressor piston through the rotation of the swash plate fixed on the rotating shaft, so as to realize the suction, compression and discharge of refrigerant. It is the relative sliding of the piston shoes on the swash plate that converts the rotational motion of the swash plate into the reciprocati...
