Problems solved by technology

Due to the low temperature resistance level of the paint selected for the existing enameled wire, it is difficult to adapt to the use environment of high temperature resistant products. Copper is used as the conductor core. Because copper has a catalytic effect on the aging of the paint, the surface of the copper is very easy to form oxidation spots. When it is welded to the finished product, there will often be false welding and false welding, which will affect the quality.

Abstract

The invention relates to the technical field of an enameled wire, in particular to a nylon enameled wire with an anti-oxidation effect, which comprises a metal wire core. A nylon surface layer is coated on the outer surface of the metal wire core; an anti-oxidation protection layer is coated on the nylon surface layer; and an insulating paint layer is coated on the anti-oxidation protection layer. As the nylon surface is coated on the metal wire core, the nylon enameled wire can be suitable for high-speed coiling; the insulating paint layer is adopted to serve as a polyurethane paint layer, thus, the nylon enameled wire is easy to color and has a good high-frequency performance and strong heat resistance; a polyester paint layer is adopted to serve as an insulating layer, thus, the nylon enameled wire has good heat resistance, good mechanical strength and good softening and ageing performance; and as the insulating paint layer is a polyester-imide composite polyamideimide pain layer, the nylon enameled wire has thermal shock resistance, refrigerant resistance and radiation resistance. The nylon enameled wire also has the characteristics of good mechanical strength of a paint film, good electrical conductivity, welding easiness and high welding quality.

Description

technical field [0001] The invention relates to the technical field of an enameled wire, in particular to a nylon enameled wire with anti-oxidation effect. Background technique [0002] At present, the development trend of enameled wire products is as follows: the electromagnetic wire products dominated by enameled wire have shifted from the research and development of new varieties with higher heat resistance to the innovation of coating of product structure, in order to improve the performance level of enameled wire and improve the processing characteristics. Purpose. Due to the low temperature resistance level of the paint selected for the existing enameled wire, it is difficult to adapt to the use environment of high temperature resistant products. Copper is used as the conductor core. Because copper has a catalytic effect on the aging of the paint, the surface of the copper is very easy to form oxidation spots. When it is welded to the finished product, there will ofte...
