Abstract
A double-layer paint film frequency conversion aluminum varnished wire comprises a wire core and coatings. An aluminum core is taken as the wire core, and the surface of the wire core is coated with a silver-copper nano alloy coating; the coatings have a composite layer structure and comprises a polyester-imide paint coating and a polyamide-imide paint coating, wherein the polyamide-imide paint coating is located on outside the polyester-imide paint coating; and a layer of frequency conversion paint coats between the polyester-imide paint coating and the polyamide-imide paint coating, and a layer of frequency conversion paint coats outside the polyamide-imide paint coating at the same time. The double-layer paint film frequency conversion aluminum varnished wire has excellent frequency conversion performance, coil interturn discharge phenomena are reduced, and the double-layer paint film frequency conversion aluminum varnished wire is suitable for being used in preparation of important elements of precise electrical equipment.
Description
Technical field
The utility model relates to enamelled wire field, is specially a kind ofly to possess double-layer paint film to reach the double-layer paint film frequency conversion aluminium enamel-covered wire of better frequency conversion effect.
Background technology
At present, enamelled wire of the prior art mainly comprises the conductor that metal core is made, its bare wire annealed softening after bag paint, cure and make, and on surface coated with polyurethane paint as insulating barrier, in general, the enamelled wire of this structure can adapt to the needs in some general field.But along with particularly developing rapidly of novel semi-conductor field of science and technology, alternating-current variable frequency motor is more and more applied, and wherein the performance requirement of the frequency conversion varnished wire of core is also more and more higher.
And the normally first application polyester-imide of conductive surface paint just of frequency conversion varnished wire of the prior art; the independent frequency conversion paint of application again; although with low cost, manufacture craft is simple; but its protective layer is too simple; in use; easily there are turn-to-turn electric discharge phenomena in coil, if long-time uninterrupted use easily causes causing equipment to lose quick, short circuit and ineffective, the enamelled wire that is not suitable as valuable precision instrument and equipment is used.
Utility model content
The technical problem that the utility model solves is to provide a kind of double-layer paint film frequency conversion aluminium enamel-covered wire, to solve the shortcoming in above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions:
Double-layer paint film frequency conversion aluminium enamel-covered wire, comprise core and coat, wherein, core adopts aluminium core and on its surface, scribbles one deck silver-copper nano alloy coating, and described coat is lamination layer structure, comprise one deck polyester-imide lacquer coat and one deck polyamidoimide lacquer coat, wherein, polyamidoimide lacquer coat is positioned at polyester-imide lacquer coat outside, meanwhile, between polyester-imide lacquer coat and polyamidoimide lacquer coat and outside polyamidoimide lacquer coat, all scribble one deck frequency conversion paint.
In the utility model, described polyester-imide lacquer coat thickness is 1/5 ~ 1/4 of composite coated layer thickness.
In the utility model, described polyamidoimide lacquer coat thickness is 1/3 ~ 1/2 of composite coated layer thickness.
In the utility model, the thickness of the frequency conversion skin of paint of application is identical between described polyester-imide lacquer coat and polyamidoimide lacquer coat and outside polyamidoimide lacquer coat.
Beneficial effect: the utility model is in aluminium core outer wrapping one deck silver-copper nano alloy coating, simultaneously, in silver-copper nano alloy coating, be coated with last layer composite paint film outward in order to strengthen the intensity of enamelled wire, simultaneously, between polyester-imide lacquer coat and polyamidoimide lacquer coat and outside polyamidoimide lacquer coat, application is coated with two-layer frequency conversion skin of paint, can effectively improve the frequency conversion performance of core, reduce electric discharge phenomena between coil turn, although structure is comparatively complicated, cost of manufacture is higher, but be used on valuable precision electronic device, can effectively improve equipment operating accuracy, improve its useful life.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the utility model preferred embodiment.
