A kind of enameled wire paint modified by organosilicon resin and preparation method thereof

Abstract

The invention discloses wire enamel modified by organic silicon resin and a preparation method of the wire enamel. The wire enamel is characterized by being prepared from the following raw materials in parts by weight: 12-14 parts of organic silicon resin, 5-7 parts of dimethyldichlorosilance, 1-2 parts of 2-aminoethyl heptadecene imidazoline, 4-6 parts of kieselguhr, 2-3 parts of ethyl acrylate, 2-4 parts of nano diatomite, 2-5 parts of 2-thiol benzimidazole, 1-2 parts of antioxidant 1010, 3-6 parts of fluorite powder, 2-3 parts of methylisothiazolinone, 20-24 parts of nylon 12, 2-3 parts of 1,6-hexamethylene diisocyanate, 7-9 parts of assistant, 100-120 parts of cresol and 80-90 parts of xylene. By adopting the wire enamel modified by the organic silicon resin, the heat tolerance of a film of the wire enamel can be effectively improved, and the production technology is simple, convenient and reliable, the wire enamel can be produced under the condition of normal pressure, and the storage stability of the product is good.

Description

technical field [0001] The invention relates to a wire enamel, in particular to a wire enamel modified by an organic silicon resin 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, hea...

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.
