Enamel varnish composition for enamel wire and enamel wire using same

摘要

Disclosed are enamel varnish compositions for an enamel wire and an enamel wire using the same. The present invention relates to enamel varnish compositions for an enamel wire in which a polymeric resin component is included in an organic solvent, wherein the polymeric resin component includes a first polyamideimide resin; and a second resin having polyamideimide in which a triazine ring is introduced into a major chain. The enamel wire, in which such a coating pigment composition is applied to the innermost layer, has the increased adhesivity of the insulated coating layer to the conducting wire, as well as the excellent physical properties such as the wear resistance and flexibility, etc.

主权项

1. An enamel wire comprising:
a conducting wire; and a plurality of insulated coating layers formed outside of the conducting wire, the plurality of insulated coating layers comprising an adhesive coating layer in direct contact with an outer surface of the conducting wire, the adhesive coating layer formed of a mixed resin comprising:
(a) a first polyamideimide resin; and(b) a second polyamideimide resin that is a linear copolymer comprising a triazine ring as a repeating monomer in the major chain, the triazine ring having a functional group comprising an imidazole group.
