High-impregnation-resistance enamelled wire and making process thereof

Abstract

The invention discloses a high-impregnation-resistance enamelled wire and a making process thereof. The high-impregnation-resistance enamelled wire mainly comprises, by mass, 10-20 parts of bisphenol-A epoxy resin, 12-17 parts of polyamide resin, 7-12 parts of butyl rubber, 1-5 parts of isocyanate, 20-25 parts of hydroxyl resin, 7-12 parts of polytetrafluoroethylene, 3-8 parts of a reactive diluent, 10-15 parts of superfine zinc oxide, 12-17 parts of nanoscale silicon micro powder, 3-6 parts of white carbon black, 10-15 parts of polyacrylate, 2-7 parts of titanium dioxide, 5-12 parts of molybdenum titanium powder, 3-6 parts of dimethylethanolamine and 10-20 parts of polyimide. The making process is simple, environment-friendly and pollution-free, the enamelled wire made by the process is high in impregnation resistance, is resistant to corrosion, high temperature and impact and capable of adapting to severe environment and protecting a cable inside the enamelled wire, and service life of the enamelled wire is prolonged.

Description

technical field [0001] The invention relates to the technical field of wire enamel preparation, in particular to a wire enamel with high impregnation resistance and a preparation process thereof. Background technique [0002] With the rapid development of industry, the fields of electronics, electrical appliances, and electrical engineering have developed rapidly. Almost all kinds of equipment, instruments, and meters related to electricity are inseparable from enameled wires, so enameled wire enamel is an irreplaceable industrial raw material. When enameled wire paint is used in harsh environments, it is easy to be impregnated after being corroded, damaging the internal cables, resulting in short circuit, leakage and other phenomena, which may cause harm to the human body and cause irreparable losses. Contents of the invention [0003] The object of the present invention is to provide a wire enamel with high resistance to dipping and its preparation process, so as to solv...
