Problems solved by technology

[0002] At present, enameled wire has been widely used in various fields, such as: motor coils, transformer coils, etc. The requirements for enameled wires are getting higher and higher. Ordinary enameled wires can no longer meet the needs of the market. Because ordinary enameled wires only use pure copper The material is produced as a conductor core, and then the outer layer is only coated with ordinary paint film as an insulating layer, which does not have strong high temperature resistance, corrosion resistance, etc., and is prone to undesirable phenomena such as oxidation and brittleness of the metal core. When welding finished products, false welding and false welding often occur, which affects the quality

Abstract

The invention relates to a lacquered wire which comprises a metal wire core, wherein a nylon surface layer is coated on the outer surface of the metal wire core, and an insulated paint layer is coated on the nylon surface layer. In the lacquered wire provided by the invention, a polyurethane paint layer which is used as the insulated paint layer is easy to stain and has good high-frequency performance and strong heat resistance; a polyester paint layer which is used as an insulated layer has good heat resistance, good mechanical strength as well as good softening and aging properties; and a polyester-imide composite polyamidoimide paint layer which is used as the insulated paint layer has good thermal shock, refrigerant resistance and radiation resistance, also has the characteristics of good mechanical strength of a paint film, good electric conductivity and good welding quality, and is easy to weld.
