Abstract
The utility model discloses a direct-welding polyurethane enameled copper round wire comprising a copper round wire, an insulation layer is coated on the surface of the copper round wire, and outer coating is coated on the surface of the insulation layer, wherein the insulation layer is direct-welding polyurethane paint, is oven-dried through laser irradiation, and is 2mm in thickness; and the outer coating is thermoset polymide resin paint with melting and adhering properties after heating. The enameled copper round wire provided by the utility model has the advantage of favorable bent resisting, voltage resisting, wear resisting and heat resisting performances.
Description
Technical field
The utility model relates to a kind of enamelling cuprum round line, particularly relates to a kind of straight weldering based polyurethane enamelling cuprum round line.
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 straight weldering based polyurethane enamelling cuprum round line, and this enamelling cuprum round line has good folding, proof voltage, anti-wear performance and heat resistance.
For solving the problems of the technologies described above the technical solution of the utility model: directly weld the based polyurethane enamelling cuprum round line, 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 insulating barrier is dried by laser radiation, and the thickness of insulating barrier is 2 millimeters, and external coating is the thermosetting polyamide lacquer type organic coating with heating melting adhesivity.
Further, in the above-mentioned straight weldering based polyurethane enamelling cuprum round line, external coating is a self-adhesive layer.
Further, in the aforesaid straight weldering based polyurethane enamelling cuprum round line, in external coating, be added with lubricant.
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 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 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.
And, utilize laser that insulating barrier is dried, realize the surface heat processing, environmental protection is quick, and end properties is stable.Because LASER HEATING has high power density, promptly concentrate high power on the unit are of the irradiation area of laser.Because power density is high, the workpiece heat loss through conduction can't in time pass away heat, and the result makes workpiece by the laser irradiation area realization Fast Heating that heats up rapidly.When LASER HEATING finishes, because still keep lower temperature in the workpiece substrate large volume during Fast Heating, being heated the zone can cool off rapidly by the heat conduction of workpiece itself.
Description of drawings
Just the utility model is described in further detail with enforcement below in conjunction with accompanying drawing:
Fig. 1 directly welds based polyurethane enamelling cuprum round line embodiment cutaway view for the utility model.
Fig. 2 directly welds the technological process of production schematic diagram of based polyurethane enamelling cuprum round line for the utility model.
Embodiment
Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to describe the technical solution of the utility model in detail.
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.And the thickness of insulating barrier is 2 millimeters.By laser radiation, the copper round wire that is coated with insulating barrier is dried.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.
As shown in Figure 2, a kind of production technology of straight weldering based polyurethane enamelling cuprum round line may further comprise the steps:
(1), copper round wire is put into drawing machine and carried out backguy;
(2), take out and to put into annealing furnace, anneal with the speed of 150 meters of per minutes;
(3), on baker, be coated with insulating barrier, insulating barrier coats with lacquer based on straight weldering based polyurethane:
(4), by laser radiation, the copper round wire that is coated with insulating barrier is dried;
(5), the temperature of lacquer in the case in the enameling machine adjusted to 30 ℃, the finished product paint vehicle is circulated in the paint bath of enameling machine, applies the operation of external coating, directly welded the based polyurethane enamelling cuprum round line.
The above is all so that the utility model conveniently to be described, in the spiritual category that does not break away from the utility model creation, the various simple covert and modification that those skilled in the art did of being familiar with this technology still belongs to protection range of the present utility model.
