Abstract
The utility model discloses a polyester-imine/polyamide-imine composite enameled copper round wire which comprises a copper round wire (1) and two insulating layers coated on the surface of the copper round wire (1), wherein the first insulating layer (2) coated on the surface of the copper round wire (1) is a polyester-imine paint coating, and the second insulating layer (3) coated on the surface of first insulating layer (2) is a polyamide-imine paint coating. With the arrangement of the two insulating layers on the surface of the copper round wire, the thermal level of the polyester-imine/polyamide-imine composite enameled copper round wire reaches the level 200, is excellent in flexibility, folding endurance, voltage resistance, paint coating continuity and heat resistance, prevents the breakage of the paint coating, and is applied to the production of deflection coils and various special electric machines with high-frequency speed-regulating function, heat resistance and cold resistance.
Description
Technical field
The utility model relates to a kind of enamelling cuprum round line, particularly a kind of 200 grades of compound enamelling cuprum round line of polyester-imide/polyamidoimide.
Background technology
It is paint film that common enamelling cuprum round line only has one deck, when making winding coil, need the skeletal fixation moulding, and its folding, proof voltage, anti-wear performance and heat resistance are relative relatively poor, film integrity is also relatively low, be usually used in general-purpose machine, electrical equipment, instrument, transformer etc., but be not suitable for deflecting coil in high-tech computer monitor and the colored picture tube, high-frequency inductor high frequency coil, telecommunications winding, high-speed induction motor etc.
The utility model content
Technical problem to be solved in the utility model is, provides a kind of polyester-imide/polyamidoimide compound enamelling cuprum round line.The thermal endurance class of this enamelled wire is 200 grades, can be used in computer monitor and the deflecting coil in the colored picture tube, telecommunications winding and high-speed induction motor, transformer etc. in the production high-tech area.
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 polyester-imide/polyamidoimide.Comprise copper round wire, be coated with two insulating barriers on the copper round wire surface, first insulating barrier that wherein is coated on the copper round wire surface is a polyester imine resin, and second insulating barrier that is coated on first surface of insulating layer is a polyamidoimide.
In the compound enamelling cuprum round line of above-mentioned polyester-imide/polyamidoimide, first insulating barrier and second insulating barrier are molten to be one.
The beneficial effects of the utility model: compared with prior art, the utility model coats two insulating barriers outside copper conductor, and wherein first insulating barrier is a polyester imine resin, has higher thermal endurance, high strength and superior isolation performance; Second insulating barrier is based on polyamidoimide, and itself and the first insulating barrier intermiscibility are good, and have high heat-resisting level, and thermal level is 200 grades.Composite enameled wire of the present utility model has good flexibility, folding resistance, proof voltage, film integrity and thermal endurance, paint film is difficult for breaking, also has lubrification, characteristic such as wear-resisting, be convenient to the coiling of coil windings, can be applicable to produce deflecting coil and various high-frequency timing, special machines such as heat-resisting, cold-resistant, also can be applicable to national defense industry, electrical equipment winding etc., and save painting process, reduce producing the harm of pernicious gas in environmental pollution and the japanning process human body.
