Abstract
The utility model discloses a self-bonding polyurethan/polyamideimide composite Litz enameled wire which is formed by twisting of at least two enameled round copper wires (1); the surface of a conductor (2) of each enameled round copper wire (1) is covered with a first insulating layer (3) and a second insulating layer (4); the first insulating layer (3) is polyurethane resin paint and the second insulating layer (4) is polyamideimide resin paint; and the surface of the second insulating layer (4) is coated with an outer coating (5). The enameled wire has good heat resistance, abrasion resistance, chemical resistance, durability, electric performance, good continuity of paint film, even magnetic field distribution, small skin effect, good transportation property, strong capacity for bearing high-frequency voltage and high anti-corona capacity, thus being applicable to the deflecting coils of color display screens (display tubes) and various high-frequency motors and electric appliances. The utility model requires no frame or dipping paint adhesion for the manufacturing of coils, reduces the volume and energy consumption of motors and electric appliances, and causes no environmental pollution resulted from dipping process.
Description
Technical field
The utility model relates to a kind of copper-clad twisted wire, the compound sharp thatch enamelled wire of particularly a kind of 200 grades of tack polyester-imide/polyamidoimides.
Background technology
Common enamel-cover copper stranded conductor is usually used in common electric machine, electrical equipment, instrument, transformer etc., but be not suitable for high-tech computer monitor, colored picture tube deflecting coil, high-frequency inductor high frequency coil, telecommunications winding, high-speed induction motor, the occasion of high frequencies such as high frequency transformer, sound equipment line, microwave oven electromagnetic disc.Existing common enamel-cover twisted wire only has an insulating barrier, and when making winding or coil, it is fixed-type to need skeleton to carry out, and its folding proof voltage anti-wear performance and heat resistance are relatively poor, and paint film easily breaks.Especially when when turning out a produce, needing some single lines to use simultaneously, do not pass through strandedly, to arrange unorderedly, the phenomenon that eddy current that produces in the high frequency place and kelvin effect increase simultaneously causes the increase of electrical equipment energy consumption, and electrical heating easily reduces useful life.
The utility model content
Technical problem to be solved in the utility model is, a kind of sharp thatch enamelled wire of tack polyester-imide that can be used in high frequency occasions such as computer monitor, colored picture tube deflecting coil, telecommunications winding and high-speed induction motor in the high-tech area, transformer is provided, thereby overcomes the deficiencies in the prior art.
For solving the problems of the technologies described above the technical solution of the utility model: the compound sharp thatch enamelled wire of a kind of tack polyester-imide/polyamidoimide.It is by at least two stranded forming of enamelling cuprum round line, is coated with first insulating barrier and second insulating barrier in the conductive line surfaces of every enamelling cuprum round line; First insulating barrier is the polyester imine resin lacquer, and second insulating barrier is the polyamide-imide resin lacquer; Be coated with external coating at second surface of insulating layer.
In the compound sharp thatch enamelled wire of above-mentioned tack polyester-imide/polyamidoimide, external coating is a self-adhesive layer.
In the compound sharp thatch enamelled wire of aforesaid tack polyester-imide/polyamidoimide, external coating is to be the self-adhesion lacquer of lacquer base with nylon.
In the compound sharp thatch enamelled wire of aforesaid tack polyester-imide/polyamidoimide, external coating contains lubricant.
The beneficial effects of the utility model: compared with prior art, sharp thatch enamelled wire of the present utility model is formed through high accuracy is stranded by many enamelling cuprum round line, every enamelling cuprum round line has two insulating barriers and an external coating, first insulating barrier is that the polyester imine resin lacquer has superior heat resistance, high strength and good insulation property, have 200 grades of high thermal endurance classs and high thermal shock resistance properties, and employing paint film multiple tracks painting process, make its folding, heat-resisting, anti-wear performance is good, high strength, paint film is difficult for breaking, and film integrity is good.Second insulating barrier is the polyamide-imide resin lacquer, and is good with first insulating barrier and external coating intermiscibility, and has high-fire resistance; External coating is to be to coat with lacquer the self-adhesion lacquer of base and contain lubricant with nylon, makes it have lubrification and resistance to wear.Sharp thatch enamelled wire of the present utility model adopts disposable strand system to be molded into the novel strand system technology of dish, realizes the disposable disc molding that is twisted into, and strands.Owing to be strands, make that its surface area is bigger, Distribution of Magnetic Field is even, and kelvin effect is little, and transmission characteristic is good, and the high frequency voltage bearing capacity is strong, and anti-corona ability is strong, and pliability is good.The utlity model has good heat-resisting, wear-resisting, chemical resistance, durability and electric property etc., film integrity is good, and Distribution of Magnetic Field is even, kelvin effect is little, and transmission characteristic is good, and the high frequency voltage bearing capacity is strong, anti-corona ability is strong, be applied to color monitor (pipe) deflecting coil, also can be widely used in various high-frequency electric machines, electrical equipment etc., make coil and need not skeleton, need not dipping lacquer bonding, motor, electrical equipment volume are reduced, cut down the consumption of energy, do not have the dipping environmentally safe.

Fig. 2 is the cross-sectional structure schematic diagram of single enamelling cuprum round line.
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Embodiment
Embodiment.As shown in Figure 1 and Figure 2, form through high accuracy is stranded, be coated with first insulating barrier 3 and second insulating barrier 4 on lead 2 surfaces of every enamelling cuprum round line 1 by multiply enamelling cuprum round line 1; First insulating barrier 3 is the polyester imine resin lacquer, second insulating barrier 4 is the polyamide-imide resin lacquer, good insulation preformance, heat-resisting, cold tolerance is good, mechanical strength is high and have the favorable chemical resistance energy, its temperature resistant grade height, good with the copper associativity, every performance meets the requirements, in second insulating barrier, 4 surface-coated external coating 5 is arranged, 5 main cementations of this external coating, it is a self-adhesive layer, optional is the self-adhesion lacquer of lacquer base in order to nylon, can also add lubricant at external coating 5, makes it have lubrification and resistance to wear.First insulating barrier 3 is coated on lead 2 surfaces, and second insulating barrier 4 is coated in first insulating barrier, 3 surfaces.First insulating barrier 3, second insulating barrier 4 and external coating 5 intermiscibilities are good, and not having influences the bad phenomenon of performance, and have more high-fire resistance and chemical-resistance.Enamelling cuprum round line 1 adopts felt or mold painting technology, realize two insulating barriers and external coating multi-pass, disposable japanning, make its mechanical performance better, and adopt disposable strand system to be molded into the novel strand system technology of dish and special-purpose disposable disc molding and the strands of being twisted into of wringing equipment realization.
