Abstract
The utility model discloses a class 220 polyimide/polyamide enamelled round copper wire, relating to an enamelled round copper wire. The class 220 polyimide/polyamide enamelled round copper wire comprises a round copper wire, wherein the polyimide paint of temperature class 220 is coated on the surface of the round copper wire to form a first insulating layer and the polyamide paint is coated on the surface of the first insulating layer to form a second insulating layer. The first insulating layer of the utility model is class 220 polyimide paint which has the ability of anti-radiation, overloading, anti ultrahigh/ultralow temperature. Secondly, the second insulating layer is provided with the polyamide insulating paint and is melted into one body with the first insulating layer after being baked and solidified. The second insulating layer and the first insulating layer are good in compatibility, relatively low in friction coefficient and excellent in heat resistance, wear resistance and electric insulating performance, significantly enhancing the wear resistance of products, providing relatively low friction coefficient, being suitable for high speed coiling production and enhancing the production efficiency.
Description
Technical field
The utility model relates to a kind of enamelling cuprum round line, particularly relates to a kind of 220 grades of compound enamelling cuprum round line of polyimide/polyamide.
Background technology
Common 220 grades of polyimide enameled wires are usually used in the enamelled wire coil windings of radioresistance, overburden, anti-high/low temperature, but owing to only have one deck insulation paint film, add the skin-friction coefficient height, wearing no resistance, do not fitting into coiling at a high speed and produce, impelling production efficiency to reduce.
The utility model content
At above-mentioned prior art, the technical problems to be solved in the utility model provides a kind of 220 grades of compound enamelling cuprum round line of polyimide/polyamide, can adapt to environment such as anti-high/low temperature, radioresistance, overburden, can adapt to the needs that coiling is at a high speed produced simultaneously.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: a kind of 220 grades of compound enamelling cuprum round line of polyimide/polyamide, comprise copper round wire, at copper round wire surface-coated thermal level is that 220 grades of polyimide varnishs constitute first insulating barrier, constitutes second insulating barrier at first surface of insulating layer polyamide coating lacquer.
In 220 grades of above-mentioned compound enamelling cuprum round line of polyimide/polyamide, first insulating barrier and second insulating barrier are molten to be one.
Compared with prior art, this practicality has the following advantages: at first be that first insulating barrier is 220 grades of polyimide varnishs, it has radioresistance, excess load, anti-superelevation/low temperature ability; Secondly, second insulating barrier is coated with polyamide insulating varnish, and molten after baked and cured with first insulating barrier be one, second insulating barrier and the first insulating barrier compatibility are good, and have lower coefficient of friction, good thermal endurance, resistance to wear and electrical insulation properties have preferably improved the resistance to wear of product greatly and lower coefficient of friction are provided, can adapt to coiling at a high speed and produce, promote production efficiency.
