Unsaturated polyester resin wire enamel and preparation method thereof

Abstract

The invention discloses unsaturated polyester resin wire enamel which is characterized by being prepared from raw materials in parts (kilogram) by weight as follows: 12-15 parts of nylon 12, 15-20 parts of the unsaturated polyester resin, 3-4 parts of zeolite powder, 8-10 parts of 2-methyl methacrylate, 1-2 parts of a cross-linking agent TAC, 1-2 parts of a titanate coupling agent TMC-TTS, 10-12 parts of diethylene glycol phthalic anhydride polymer, 3-5 parts of stearic acid, 1-2 parts of an accelerator TMTD, 1.4-1.7 parts of diethylenetriamine, 7-9 parts of auxiliaries, 100-120 parts of cresol and 60-70 parts of xylene. The unsaturated polyester resin wire enamel has the advantages that the surface friction coefficient of the wire enamel is reduced, furthermore, the whole performance of the wire enamel is promoted, and the unsaturated polyester resin wire enamel is suitable for various application places.

Description

technical field [0001] The invention relates to a wire enamel, in particular to an unsaturated polyester resin 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 resist...

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.
