Abstract

The invention relates to a wire field and particularly relates to an enamelled wire. The enamelled wire comprises a metal core, wherein the outer surface of the metal core is sequentially coated with an inorganic micro particle layer, a wear-resistant insulation layer and insulation paint layer, the wear-resistant insulation layer is a nylon surface layer dipped in epoxy resin, and insulation paint is mixture of polyurethane insulation varnish and high temperature color concentrate. The enamelled wire has advantages of ultraviolet irradiation resistance, high temperature resistance for melting prevention and strong acid and alkali resistance capability.

Description

technical field [0001] The invention relates to the field of electric wires, in particular to an enameled wire and a production process thereof. Background technique [0002] Alloy enameled wire has been widely used as high-fidelity wire in electromagnetic wire and electroacoustic industry due to its excellent electrical conductivity, corrosion resistance and superior process performance. Now the paint performance on the market is quite single, such as insulation, resistance Poor acid-base performance, low viscosity, easy to fall off, etc., easy to burn at high temperature, can not meet the performance requirements of enameled wire, and has great safety hazards. [0003] The enameled wire has to go through multiple heat treatments and other processes during the production process. The heat treatment parameters and other process parameters of the enameled wire during the heat treatment process will affect the performance of the enameled wire, such as poor insulation, easy bur...
