Multi-resin composite wire enamel and preparation method thereof

Abstract

The invention discloses multi-resin composite wire enamel and a preparation method thereof. The multi-resin composite wire enamel is characterized by being prepared from raw materials in parts by weight as follows: 12-15 parts of phenolic resin, 3-4 parts of polyester silicone oil, 2-3 parts of polyvinyl chloride, 2-3 parts of isocyanate, 7-9 parts of diethylene glycol diethyl ether, 5-7 parts of dipropylene glycol monomethyl ether, 12-15 parts of polyisobutene, 3-8 parts of ABS (acrylonitrile butadiene styrene) resin, 12-13 parts of PP (polypropylene) resin, 12-15 parts of nylon 12, 7-9 parts of an assistant, 100-110 parts of m, p-cresol and 100-110 parts of xylene. The production cost of an enameled wire is low, the production speed is high, and the labor productivity is improved.

Description

technical field [0001] The invention relates to a wire enamel, in particular to a multi-resin composite wire enamel and a preparation method thereof. Background technique [0002] Enameled wire is a kind of electrical material. It processes a thin layer of high-strength insulating layer on the surface of a round copper wire to insulate it from the outside world. According to the specifications, it can be processed into a wool thread thinner than a hair, and a yarn-covered thread as thick as a thumb. Enameled wire has good insulation effect and waterproof ability. It is widely used in electrical appliances, such as motors, generators, water pumps, electromagnets, electric welding machines, household appliances, wireless communications, speakers, telegraphs, transformers, etc. Enameled wire enamel is a necessary insulating material for the production of enameled wire. Enameled wire enamel requires good adhesion, mechanical strength, insulation performance, heat resistance, w...

AI Technical Summary

Problems solved by technology

Enameled wire enamel is a necessary insulating material for the production of enameled wire. Enameled wire enamel requires good adhesion, mechanical strength, insulation performance, heat resistance, wear resistance, salt spray resistance and harsh environment resistance, etc., but ordinary wire enamel has resistance to It is difficult to meet the requirements of different environments due to problems such as thermal resistance, poor wear resistance, insufficient strength, and heat resistance below 120°C.
