Description
Technical field
The present invention relates to a kind of enamelling cuprum round line, particularly relate to a kind of straight weldering based polyurethane enamelling cuprum round line and production technology thereof.
Background technology
Existing common enamelling cuprum round line only contains an insulating barrier, when making coil, needs fixedly moulding of skeleton; And its folding, proof voltage, anti-wear performance and heat resistance are relatively poor, and paint film is prone to break, and it can not directly be used for welding; Lubrification is also not enough; Be prone to 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, transformer etc.; But be not suitable for occasions such as high-tech computer monitor, colour kinescope deflecting coil, high-frequency inductor high frequency coil, telecommunications winding, high-speed induction motor, can't satisfy the requirement of telecommunications, electron trade.
Summary of the invention
Technical problem to be solved by this invention 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 technical scheme of the present invention: directly weld the based polyurethane enamelling cuprum round line, comprise copper round wire, be covered with insulating barrier, be coated with external coating at surface of insulating layer in the copper round wire surfaces coated; Wherein insulating barrier is straight weldering based polyurethane lacquer, and insulating barrier is dried through laser radiation, 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 present invention provides 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 carry 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 is the main body with straight weldering based polyurethane lacquer:
(4), through 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.
Further, in the production technology of above-mentioned straight weldering based polyurethane enamelling cuprum round line, external coating is a self-adhesive layer.
Further, in the production technology of aforementioned straight weldering based polyurethane enamelling cuprum round line, in external coating, be added with lubricant.
Beneficial effect of the present invention: compared with prior art; The present invention 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, and this kind insulating varnish has good insulation property, has the thermosetting polyamide resin external coating of 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 invention 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, and coil hardness is high 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, and 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 big volume of workpiece substrate during Fast Heating, being heated the zone can cool off rapidly through the heat conduction of workpiece itself.
