Abstract
The utility model relates to the technical field of enameled wires, in particular to a polyurethane enameled wire which is coated with nylon finishing coat and has an anti-oxidization effect. The polyurethane enameled wire comprises a copper core and is characterized in that the nylon finishing coat is coated on the external surface of the copper core, an anti-oxidization protective layer is coated on the nylon finishing coat, and a polyurethane paint layer is coated on the external surface of the anti-oxidization protective layer. Since the nylon finishing coat is coated on the external surface of the copper core of the polyurethane enameled wire, the polyurethane enameled wire is more suitable for high-speed winding; since a silver coating layer or a tin coating layer is used as the anti-oxidization protective layer, the anti-oxidization effect can be effectively taken; and since a polyurethane layer is used as an insulating layer, the dying is easy, the high-frequency performance is good, the heat resistance is high and the product formability is good.
Description
Technical field
The utility model relates to a kind of technical field of enamelled wire, especially a kind of polyurethane enamelled wire that is coated with nylon surface layer and oxidation-protective effect.
Background technology
At present; enamelled wire has been widely applied to every field; for example: the coil of motor; coil of transformer or the like; requirement for enamelled wire is also more and more higher; common enamelled wire has not satisfied the demand in market; because common enamelled wire utilizes pure copper material as conductor thread core production; copper has aging catalytic action to coat of paint; extexine applies common paint film again as insulating barrier then; do not have very strong heat-resisting quantity; corrosion resistance etc., and the oxidation of metal core appears easily; bad phenomenon such as embrittlement are when it carries out the finished product welding; rosin joint appears through regular meeting; the dry joint phenomenon influences quality.
The utility model content
The technical problems to be solved in the utility model is: in order to overcome the above-mentioned middle problem that exists, provide a kind of have oxidation effectiveness and suitable the coiling at a high speed and the good polyurethane enamelled wire of product shaping.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of polyurethane enamelled wire; comprise copper core; described copper core outer surface is coated with the nylon surface layer, is coated with the protection against oxidation layer on the nylon surface layer, is coated with the polyurethane enamelled coating on the protection against oxidation layer outer surface.
In order to play better oxidation-protective effect, described antioxidation coating is tin coating or silver coating.
The beneficial effects of the utility model are; polyurethane enamelled wire of the present utility model; be coated with the nylon surface layer at the copper core outer surface; be fit to coiling at a high speed more; adopt silver coating or tin coating as the protection against oxidation layer, can effectively play oxidation-protective effect, utilize polyurethane paint as insulating barrier; have advantages such as easy coloring, high frequency performance is good, heat resistance is good, product shaping is good.
