Abstract
The utility model discloses an enameled wire with tolerance to R134a refrigerant, which comprises a copper wire (1) and two insulating layers coated on the surface of the copper wire (1), wherein the first insulating layer (2) is formed by coating polyester-imine paint on the surface of the copper wire (1), the second insulating layer (3) is formed by coating polyester-imine paint on the surface of the first insulating layer (2), and a surface lubricating layer (4) is coated on the surface of the second insulating layer (3) and is compatible to the R134a refrigerant. The enameled wire with tolerance to R134a refrigerant is an environment-friendly product developed to improve the global environment and is mainly applied to the Freon-free refrigerator and the Freon-free air conditioner.
Description
Technical field
The utility model relates to a kind of enamelled wire, relates in particular to a kind of special varnish envelope curve that is applicable to the cold-producing medium of anti-R134a.
Background technology
The used enamelled wire of general refrigerator and air conditioner compressed pump motor is the enamelled wire of anti-fluorine coiled, and the cold-producing medium of usefulness is fluorine Lyons, can destroy atmospheric ozone layer.Freon-free refrigerator, fluorine-free air conditioning to compliance with environmental protection requirements adopt R134a cold-producing medium and ester class oil as refrigeration working medium usually, but at present immiscible as its greasing substance of the common enamelled wire of anti-fluorine of surface lubricant and R134a and ester class oil with common paraffin, be not suitable for freon-free refrigerator and air-conditioning.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of enamelled wire that is applicable to the cold-producing medium of anti-R134a, and this enamelled wire is applicable to freon-free refrigerator and air-conditioning.
For solving the problems of the technologies described above the technical solution of the utility model: a kind of enamelled wire that is applicable to the cold-producing medium of anti-R134a.Comprise copper conductor, in the copper conductor surface-coated two insulating barriers are arranged, first insulating barrier wherein is the polyester-imide lacquer, is coated in the copper conductor surface; Second insulating barrier is the polyamidoimide lacquer, is coated in first surface of insulating layer; Be coated with the surface lubrication layer that mixes with the R134a cold-producing medium at second surface of insulating layer.
In the above-mentioned enamelled wire that is applicable to the cold-producing medium of anti-R134a, the surface lubrication layer is a polyester an aromatic plant metioned in ancient books compound.
The beneficial effects of the utility model: compared with prior art, the utility model is a kind of for improving the Green Product that earth environment is developed, and is mainly used in freon-free refrigerator and air-conditioning.This enamelled wire internal layer is coated with polyesterimide wire enamel, and the second layer is coated with polyamide-imide enamelled wire varnishes, forms through baked and cured, and surface lubricant is a polyester an aromatic plant metioned in ancient books compound, has intermiscibility with the R134a cold-producing medium, applicable to freon-free refrigerator and air-conditioning.The utility model has under the long term seal pressure condition combination properties such as corresponding thermal endurance and good electric, mechanical, chemistry, have good anti-refrigerant and oil resistance, have at a high speed coiling, automatically in the adaptability of processing and manufacturings such as rule, pressure shaping, and the compression pump motor of employing the utility model enamelled wire coiled, can use new refrigerant R134a, ozone layer is not had destruction.
Description of drawings
Fig. 1 is a lateral cross section structural representation of the present utility model.
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Embodiment
Embodiment.As shown in Figure 1, comprise copper conductor 1 and be coated in two insulating barriers on copper conductor 1 surface that wherein first insulating barrier 2 is coated in copper conductor 1 surface.For guarantee good insulation preformance, heat-resisting, cold tolerance is good, mechanical strength is high and have the favorable chemical resistance energy, and can guarantee combining closely property with copper conductor 1, first insulating barrier 2 is selected the material based on polyester imine resin for use, and its temperature resistant grade height is good with the copper associativity; Second insulating barrier 3 is coated in first insulating barrier, 2 surfaces, and it is the insulating material of base that second insulating barrier 3 is selected for use with the polyamidoimide.Second insulating barrier 3 and first insulating barrier, 2 intermiscibilities are good, and not having influences the bad phenomenon of performance, and have more high-fire resistance and chemical-resistance.On second insulating barrier, 3 surfaces surface lubrication layer 4 is arranged, surface lubrication layer 4 is selected coefficient of friction polyester an aromatic plant metioned in ancient books compound or other polyester-based compounds low, that mix with the R134a cold-producing medium for use.
Execution mode of the present utility model is not limited to the foregoing description, all belongs within the protection range of the present utility model in the various variations of making under the prerequisite that does not break away from the utility model aim.
Claims (2)
1. an enamelled wire that is applicable to the cold-producing medium of anti-R134a comprises copper conductor (1), it is characterized in that: in copper conductor (1) surface-coated two insulating barriers are arranged, first insulating barrier (2) wherein is coated in copper conductor (1) surface for the polyester-imide lacquer; Second insulating barrier (3) is coated in first insulating barrier (2) surface for the polyamidoimide lacquer; The surface lubrication layer (4) that mixes with the R134a cold-producing medium is arranged in second insulating barrier (3) surface-coated.
2. the enamelled wire that is applicable to the cold-producing medium of anti-R134a according to claim 1 is characterized in that: described surface lubrication layer (4) is a polyester an aromatic plant metioned in ancient books compound.
