Abstract
The utility model relates to a three-composite self-lubricating refrigerant-resistant enamelled wire, comprising a copper wire and three insulating layers coated on a surface of the copper wire; wherein the surface of the copper wire is coated with three layers of insulating layers from the inside out, a first insulating layer is polyester-imine insulating varnish, a second insulating layer is polyamide-imide insulating varnish, and a third insulating layer is self-lubricating type polyamide-imide insulating varnish. According to the three-composite self-lubricating refrigerant-resistant enamelled wire of the utility model, by adopting a three-composite coating technology to take advantage of varnish of the each coating, and by adopting a thin-varnish multiple-coating varnishing way to enhance adhesiveness of a varnish film at the each layer, refrigerant resistance, oil resistance, wear resistance, scratch resistance, and heat resistance of the enamelled wire can be raised, thus the three-composite self-lubricating refrigerant-resistant enamelled wire of the utility model is very suitable for being used by high-speed automation winding equipment in a motor manufacturing industry.
Description
Technical field
The utility model relates to a kind of enamelled wire, specifically a kind of refrigerator, air-conditioning and large-scale refrigeration plant enameled wire for compressor motor.
Background technology
Development along with the modern fabrication equipment technology, the motor manufacturing generally adopts high-speed automated spooling equipment coiling motor coil, various mechanical performances to enamelled wire have proposed higher requirement, require enamelled wire to have certain mechanical strength, stronger resistance to wear, scratch resistance power and good lubrification.For reducing enamelled wire surface coefficient of friction when the high speed winding, usually at lubricants such as enamelled wire surface paraffines, but owing to contain ester class machine oil in the used novel alternative chlorofluoro carbon (R134a, R600a etc.) of environmental protection air-conditioning, refrigerator, the dissolved extraction of the greasing substances such as paraffin meeting, extract causes the refrigerating system capillary to stop up, and damages the operation of compressor.In addition, because the compressor pressure that the winding in the motor is changed, enamelled wire has the character that absorbs refrigerant, and after pressure was removed, foamed phenomenon can appear in enamelled wire surface.Therefore, refrigeration compressor motor not only will satisfy thermal endurance, mar proof with enamelled wire, and cold-resistant matchmaker's extractibility, anti-foaminess are claimed, and general enamelled wire can't satisfy simultaneously.
Summary of the invention
The purpose of this utility model is to provide a kind of three composite self-lubricatings cold-resistant matchmaker's enamelled wire for the problem of above-mentioned enamelled wire existence.
Scheme of the present utility model is: comprise copper conductor, in the copper conductor surface-coated three insulation enamelled coatings are arranged; Wherein the first insulation enamelled coating is the polyester-imide layer, is coated in the copper conductor surface; The second insulating barrier is the polyamidoimide layer, is coated in the first surface of insulating layer; The 3rd layer is the self-lubricating type polyamidoimide, is coated in the second surface of insulating layer.
Advantage of the present utility model: (1) adopts three composite coating technologies, each coating reasonable coordination, bring into play the advantage of each coating paint, prime coat is that polyester-imide, middle enamelled coating are polyamidoimide, guaranteed paint film heat resistance and softening breakdown performance, top coat layer is selected the self-lubricating type polyamidoimide, improves surface lubrication, reduce skin-friction coefficient, and be applicable to R134a, R600a novel refrigerant.(2) paint-on technique of the thin lacquer overbrushing of employing guarantees that the per pass paint film fully solidifies, and the attached power of enamelled coating is strong, wear-resisting scratch resistance.The utlity model has thermal endurance, cold-resistant matchmaker's extractibility, anti-foaminess, have the adaptability in processing and manufacturings such as High-Speed Automatic coilings, the enamelled wire overall performance is improved.
Description of drawings
Accompanying drawing is lateral cross section structural representation of the present utility model.
Embodiment
As shown in the figure, comprise copper conductor 1 and be coated in three insulating barriers on copper conductor 1 surface that wherein the first insulating barrier 2 is coated in copper conductor 1 surface, selecting polyester-imide is insulating material, improves the tack of paint film; The second insulating barrier 3 is coated in the first insulating barrier 2 surfaces, and selecting polyamidoimide is insulating material, has guaranteed paint film heat resistance and softening breakdown performance; Three-layer insulated layer 4 is coated in the second surface of insulating layer, selects the self-lubricating type polyamidoimide.By applying three-layer insulated layer, improved the cold-resistant matchmaker of enamelled wire, oil resistance, paint film adhesion is strong, wear-resisting, scratch resistance, heat-resisting, the high-speed automated spooling equipment that is fit to very much the motor manufacturing uses.
Claims (2)
1. the cold-resistant matchmaker's enamelled wire of composite self-lubricating comprises copper conductor (1), it is characterized in that copper conductor (1) surface-coated has three-layer insulated layer.
2. the cold-resistant matchmaker's enamelled wire of a kind of three composite self-lubricatings according to claim 1, it is characterized in that it is polyester-imide insulating varnish that three-layer insulated layer is respectively the first insulating barrier (2) from inside to outside, the second insulating barrier (3) is polyamide-imide insulating varnish, and the 3rd layer (4) are the self-lubricating type polyamide-imide insulating varnish.
