Wire enamel with high temperature classification and preparation method

Abstract

The invention discloses wire enamel with high temperature classification. The wire enamel is characterized by being prepared by raw materials in parts by weight (kilogram) as follows: 30-35 parts of nylon 12, 10-12 parts of E-12 epoxy resin, 1-2 parts of magnesium hydrate, 8-10 parts of aluminum triphosphate, 12-15 parts of ethylene glycol, 6-9 parts of dimethyl terephthalate, 4-6 parts of trimethyl trimellitate, 2-3 parts of 3-methylphenol, 8-10 parts of nano bentonite, 10-12 parts of tripropylene glycol diacrylate, 1-2 parts of nano emery powder, 2-3 parts of dicumyl peroxide DCP, 8-12 parts of potassium hexatitanate whiskers, 7-9 parts of an auxiliary, 120-130 parts of cresol and 110-120 parts of xylene. With the adoption of the wire enamel with high temperature classification, forming of a paint film with uniform, dense and smooth surface can be facilitated during coating in the follow-up process, micropores are greatly reduced, and scratch resistance, harness, salt mist resistance and severe environment resistance of the paint film are remarkably improved.

Description

technical field [0001] The invention relates to a wire enamel, in particular to a wire enamel with high heat-resistant grade 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 resi...

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.
