Description
Technical field
The present invention relates to a kind of enamelling cuprum round line, especially a kind of wear-resisting enameled wire.
Background technique
The enamelling cuprum round line needs of big specification meet normal use using thicker paint film, still, thicker paint film and
Adhesive capacity between copper round wire is poor, and leading to the enameled wire of larger specification, paint film is easily peeled in use for some time, influences
Enameled wire normal use shortens the service life of enameled wire.Therefore, existing technology has that service life is short.
Summary of the invention
The object of the present invention is to provide a kind of wear-resisting enameled wires.The present invention has the characteristics that be able to extend service life.
Technical solution of the present invention：A kind of wear-resisting enameled wire, including copper round wire, copper round wire are externally provided with insulating layer, insulating layer
It is externally provided with the first nylon coating and the second nylon coating, the second nylon coating is externally provided with polyamidoimide paint layer, the first nylon
Nano-sized carbon tube layer is equipped between coating and the second nylon coating；The insulating layer includes polyamide paint layer, metal oxide polyamides
Amine acid imide paint layer and polyurethane paint layer, and polyamide paint layer, metal oxide polyamidoimide paint layer and polyurethane paint layer
Between thickness proportion be 1:1.5:2.
In a kind of wear-resisting enameled wire above-mentioned, the polyamidoimide paint layer is applied including five strata amide imide paints
Layer, every strata amide imide lacquer coat with a thickness of 0.012mm-0.020mm.
In a kind of wear-resisting enameled wire above-mentioned, the nano-sized carbon tube layer includes being helically wound around receiving outside the first nylon coating
Rice carbon pipe, and the helical angle of carbon nanotubes is 60-70 degree.
In a kind of wear-resisting enameled wire above-mentioned, the thickness proportion between first nylon coating and the second nylon coating is
1:1.5。
In a kind of wear-resisting enameled wire above-mentioned, first nylon coating outer surface is uniformly provided with one group of retention bead.
Compared with prior art, the present invention outside copper round wire by coating by polyamide paint layer, metal oxide polyamide
The insulating layer that acid imide paint layer and polyurethane paint layer are constituted, and the thickness proportion of three is specifically limited, it can not only play good
Insulation shielding performance, while also have preferable adhesion property；By the way that the first nylon coating, nano-sized carbon are arranged outside insulating layer
Tube layer and the second nylon coating are matched using the fabulous toughness of carbon nanotubes, and with the first nylon coating and the second nylon coating
It closes, so as to improve the toughness of copper round wire well, effectively reduces the expulsion rate of paint film, extend the use of enamelling cuprum round line
Service life, while carbon nanotubes also has good heat dissipation performance, so as to effectively improve the radiating rate of enamelling cuprum round line.
Present invention polyamide coating acid imide paint layer also outside the second nylon coating is adhered to using the height of polyamide coating acid imide paint layer
Performance prevents pull-away phenomenon so as to improve the adhesion property of enamelling cuprum round line on the whole.In conclusion
The present invention has the characteristics that be able to extend service life.
In addition, by being uniformly provided with one group of retention bead in the first nylon coating outer surface, so as to improve nano-sized carbon
The adhesive ability of pipe prevents to be displaced.
