Abstract
The utility model discloses a solderable polyurethane/polyamide composite enameled round copper wire, wherein the surface of a round copper wire (1) is covered with a first insulting layer (2) and a second insulating layer (3); the first insulting layer (2) is solderable polyurethane paint and covers the surface of the round copper wire (1), and the second insulating layer (3) is polyamide paint and covers the surface of the first insulting layer (2). The enameled round copper wire has good property at a thermal level of 155 DEG C, higher abrasion resistance and lubrication capability, satisfies the requirement of high speed windings and can be widely applied to the production of electric tools, high-frequency transformers, special motors and windings of electric appliances.
Description
Technical field
The utility model relates to a kind of enamelling cuprum round line, particularly a kind of 155 grades of compound enamelling cuprum round line of straight weldering based polyurethane/polyamide that are used to produce usefulness such as motor, electric tool, transformer.
Background technology
Common enamelling cuprum round line is usually used in common electric machine, electrical equipment, instrument, transformer, but can't be applicable to that coiling is produced at a high speed when making coil, because its coefficient of friction, resistance to wear are not enough.
The utility model content
Technical problem to be solved in the utility model is, provides a kind of straight weldering based polyurethane/polyamide compound enamelling cuprum round line.This enamelled wire has 155 ℃ high heat-stage performance and higher resistance to wear and lubricating ability, can satisfy the requirement of coiling at a high speed, can be widely used in the production of electric tool, high frequency transformer.
For solving the problems of the technologies described above the technical solution of the utility model: the compound enamelling cuprum round line of a kind of straight weldering based polyurethane/polyamide.Be coated with first insulating barrier and two insulating barriers of second insulating barrier on the copper round wire surface of this enamelled wire, wherein first insulating barrier is straight weldering based polyurethane lacquer, is coated on the surface of copper round wire; Second insulating barrier is a polyamide paint, is coated on the surface of first insulating barrier.
In the above-mentioned compound enamelling cuprum round line of straight weldering based polyurethane/polyamide, second insulating barrier and first insulating barrier are molten to be one.
The beneficial effects of the utility model: compared with prior art, enamelled wire of the present utility model has two insulating barriers, wherein first insulating barrier insulating varnish that to be coated with straight weldering based polyurethane be main component makes it have straight weldering, and possesses higher thermal endurance, high strength and good insulation property; Second insulating barrier is the insulating varnish of main component coated with polyamide, and after baked and cured, become one with first insulating barrier, second insulating barrier and the first insulating barrier intermiscibility are fine, thermal endurance class is higher, and has lower coefficient of friction, good heat-resisting, wear-resisting, chemical-resistance and good electric property etc.The utlity model has 155 ℃ high heat-stage performance, higher resistance to wear and lubricating ability, can satisfy the requirement of coiling at a high speed, can be widely used in the production of electric tool, high frequency transformer, special machines, electrical equipment winding, and its directly the property of weldering property greatly facilitate the use of enamelled wire on each electric appliances.
Description of drawings
Fig. 1 is a cross section structure schematic diagram 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, be coated with first insulating barrier 2 and second insulating barrier 3 on the surface of copper round wire 1, wherein first insulating barrier 2 is straight weldering based polyurethane lacquer, is coated on the surface of copper round wire 1; Second insulating barrier 3 is a polyamide paint, is coated on the surface of first insulating barrier 2, and molten after second insulating barrier, 3 baked and cured with first insulating barrier 2 be one.
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.
