Alkyd resin wire enamel and preparation method thereof

Abstract

The invention discloses an alkyd resin wire enamel, which is characterized by being prepared from the following raw materials by weight part (kg): 12-15 of long oil length alkyd resin, 12-15 of amino resin, 12-15 of nylon 12, 1-2 of 2-hydroxy4-octyloxy benzophenone, 1-2 of methylbenzotriazole, 2-3 of 2, 6-di-tert-butyl m, p-cresol, 2-3 of monobutyltin oxide, 5-10 of propylene glycol methyl ether acetate, 3-5 of zinc naphthenate, 2-5 of polydimethylsiloxane, 1-2 of 2-thiolbenzimidazole, 14-18 of polyvinyl alcohol, 10-14 of vermiculite powder, 1-2 of an antioxidant RD, 7-9 of an assistant, 80-90 of m, p-cresol, and 100-120 of dimethylbenzene. Compared with the prior art, the processing method involved in the invention is simple, and the wire enamel paint film prepared by the invention has the advantages of good stability and strong chemical corrosion resistance, and can be applied to electric appliance in special industries to maintain good electrical insulation performance and mechanical properties. The production cost can be greatly reduced, and the work efficiency can be improved.

Description

technical field [0001] The invention relates to a stabilizer, in particular to an alkyd 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 resistance, wear 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.
