Description
Technical field
The present invention relates to a kind of preparations of car air conditioning compressor slanting plate, and in particular to it is a kind of based on cyanate it is wear-resisting from
Lubricate the preparation method of swash plate.
Background technique
Automobile air conditioner compressor is the critical component of automotive air-conditioning system, and wherein compressor of oblique-plate-type air conditioner is with the letter of its structure
Single, adjusting is reliably, the balance quality of machine is preferable, can reach the advantages that higher revolving speed, becomes in current automotive air-conditioning system
Using most common compressor, account for about 80% or so of the passenger car market share, and has the tendency that further expansion.
In compressor of oblique-plate-type air conditioner, swash plate rotates at the same speed with the main shaft for passing through swash plate, and swash plate is connected by crawler shoe and piston
It connects driving piston to move reciprocatingly, then passes through the compression of air-breathing and the unidirectionally controlled completion gas of exhaust;Swash plate revolving speed is controllable
The frequency of reciprocating motion of the pistons, the angle between swash plate and main shaft is adjustable, by the inclination angle control piston reciprocating fortune of swash plate
The size of dynamic stroke.The performance of swash plate directly determines the service life of compressor, therefore is that compressor of oblique-plate-type air conditioner is very crucial
Component.
Compressor of oblique-plate-type air conditioner moves initial stage, and lubricating oil not yet reaches swash surfaces, and swash plate is needed in no lubricating oil
Drying condition under run;After the surface that lubricating oil reaches swash plate, swash plate still needs to run (revolving speed under high speed and top load
Constantly change with load), thus, the service condition of swash plate is very harsh, therefore it is required that swash plate is in non lubricant oil state
All there is good wear-resisting and anti-card plug performance under (dry friction) and lubricating oil state.
Swash plate is made of substrate and wear-resistant coating, is that deposition a layer thickness is 20~30 microns on the substrate of steel or aluminium
Macromolecule layer, the macromolecule layer are made of wear-resisting molybdenum disulfide, graphite, PTFE and base resin and reinforced partly material
Coating, also known as sliding contact layer.The preparation of swash plate and selection directly determine the performance of swash plate, wearability including swash plate, resistance to
Hot and self-lubrication.Base resin plays the role of bonding in wear-resistant coating, and since the intrinsic of resin material lacks
Fall into, heat resistance is relatively low compared with other components, it is therefore desirable to constitute the base resin of swash plate in addition to having excellent adhesion, it is resistance to
Outside mill property, the heat resistance that should also have.
The existing base resin for swash plate preparation is generally polyimides or polyamidoimide, can be certain
The self-lubricating property of improvement swash plate in degree, but the frictional property of the wear-resistant coating thus constituted, especially dry friction performance, with
And cementability also needs to improve;In addition there are also some about the report that polyether-ketone, polyether sulfone or polyethersulfone ketone material are used for swash plate
Road, such material has certain heat resistance, but cementability is poor, the poor compatibility with remaining material;And existing basis
Resin cannot be dissolved in the Conventional solvents of such as acetone, and requiring the solvent being more toxic, not environmentally could dissolve, and be harmful to society
Environment, while the curing process of existing base resin is very harsh, requires more than 300 DEG C, the time is all a few houres, is not only increased
Standby difficulty is added, social energy consumption is further increased.Existing swash plate is equal in terms of self-lubrication, heat resistance, wearability and cementability
There are certain shortcomings.
