Abstract
The utility model discloses a thermal-bonding direct-welding polyurethane paint copper-coating round wire, comprising a copper round wire (1), an insulation layer (2) coated on the surface of the copper round wire (1), an external coating layer (3) coated on the surface of the insulation layer (2), wherein the insulation layer (2) is direct-welding polyurethane paint and the external coating layer(3) is thermosetting polyamide resin paint with heating fusing character. The thermal-bonding direct-welding polyurethane paint copper-coating round wire is a self-adhesive wire with stronger comprehensive performance, better wear resistance and electric behavior and durability and the heat level is 155 level. The insulation layer has direct-welding character and needs not remove paint at high temperature and can directly weld when producing electric appliance coil to prevent human being hurt by removed paint. The labor intensity is reduced and welding quality is ensured. The outer coating layer use self-adhesive coating layer in no need of immersed-lacquer adhesion without skeleton forming. The manufacture technology is simple without environmental pollution and lubricant is added into the outer coating layer to make the outer coating with lubricity and wear resistance.
Description
Technical field
The utility model relates to a kind of enamelling cuprum round line, and the based polyurethane enamelling cuprum round line is directly welded in particularly a kind of 155 grades of heat bondings
Background technology
Existing common enamelling cuprum round line only contains an insulating barrier, when making 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, paint film easily breaks, it can not be directly used in welding, lubrification is also not enough, easily cause mechanical damage in the course of processing, and cause the converted products performance change thus, be usually used in common electric machine, electrical equipment, instrument, transformers etc. but are not suitable for high-tech computer monitor, the colour kinescope deflecting coil, the high-frequency inductor high frequency coil, the telecommunications winding, occasions such as high-speed induction motor can't satisfy telecommunications, the requirement of electron trade.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of heat bonding directly to weld the based polyurethane enamelling cuprum round line, this enamelling cuprum round line has good folding, proof voltage, anti-wear performance and heat resistance, thermal endurance class is 155 grades, can be used in the computer monitor in the production high-tech area, colour kinescope deflecting coil, telecommunications winding etc.
For solving the problems of the technologies described above the technical solution of the utility model: the based polyurethane enamelling cuprum round line is directly welded in heat bonding.Comprise copper round wire, insulating barrier is arranged, be coated with external coating at surface of insulating layer in the copper round wire surface-coated; Wherein insulating barrier is straight weldering based polyurethane lacquer, and external coating is the thermosetting polyamide lacquer type organic coating with heating melting adhesivity.
Above-mentioned heat bonding is directly welded in the based polyurethane enamelling cuprum round line, and external coating is a self-adhesive layer.
Aforesaid heat bonding is directly welded in the based polyurethane enamelling cuprum round line, is added with lubricant in external coating.
The beneficial effects of the utility model: compared with prior art, the utility model is as a kind of novel Self-binding cord with strong combination property, its insulating barrier is evenly to be coated on conductive surface in order to the insulating varnish that straight weldering based polyurethane is a main component, this kind insulating varnish has good insulation property, the thermosetting polyamide resin external coating that has the heating melting adhesivity then in surface-coated, and after baked and cured, have good resistance to wear and good electric property, durability.Insulating barrier is chosen the higher insulating varnish of heat-resisting level, makes it have 155 grades of high heat-stage performances.Insulating barrier of the present utility model has straight weldering characteristic, at high temperature need not coating removal, have direct welding function, when making electric apparatus coil, can directly weld, when avoiding depainting to the human injury; Can reduce labour intensity, guarantee welding quality.Isolation layer intensity is high and have the superior isolation performance, and thermal level is 155 grades, and is good with the external coating intermiscibility, has higher thermal endurance class, coil hardness height after the heat bonding.External coating adopts from adhesive coating layer, it is bonding to make it need not dipping lacquer, also can exoskeletal moulding, manufacturing process is simple, can not cause environmental pollution, and in external coating, be added with lubricant, make it have lubrification and resistance to wear, can be widely used in computer monitor, colour kinescope deflecting coil, telecommunications winding, high-frequency inductor high frequency coil, high-speed induction motor in the production high-tech area etc.
Description of drawings
Fig. 1 is a 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, in the surface-coated of copper round wire 1 layer insulating 2 is arranged, this insulating barrier 2 coats with lacquer based on straight weldering based polyurethane, has high-intensity performance and good insulation property, and thermal level is 155 grades.Be coated with one deck external coating 3 in the outside of insulating barrier 2.External coating 3 is a self-adhesive layer, to have the thermosetting polyamide lacquer type organic coating of heating melting adhesivity, is added with lubricant in external coating 3, makes it have lubrification and resistance to wear.
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.
