Synthetic wire enamel and preparation method thereof

Abstract

The invention discloses synthetic wire enamel which is prepared from raw materials in parts by weight (kilogram) as follows: 10-12 parts of trimethylolpropane triacrylate, 10-12 parts of trimellitic anhydride, 5-8 parts of maleic anhydride, 4-5 parts of tetraethylene imine, 6-8 parts of titanium oxide, 3-4 parts of precipitated barium sulphate, 10-12 parts of nylon 12, 20-24 parts of polyacrylate, 1-3 parts of diethylenetriamine, 5-7 parts of ceramic slag powder, 4-7 parts of zinc oxide, 1-2 parts of aluminum hydroxide, 13-14 parts of microcrystalline wax, 7-9 parts of an assistant, 90-100 parts of m, p-cresol and 100-120 parts of xylene. The preparation method is simple, the cost is low, and the prepared wire enamel has good heat resistance, cold resistance, abrasion resistance and oil resistance.

Description

technical field [0001] The invention relates to a wire enamel, in particular to a synthetic 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, wear resistan...

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.
