Wire enamel and preparation method thereof

Abstract

The invention discloses wire enamel which is characterized by being prepared by raw materials in parts by weight (kilogram) as follows: 3-5 parts of isocyanate, 7-9 parts of di-tetradecyl carbon alcohol ester, 12-15 parts of epoxy phenolic resin, 8-12 parts of polyester acrylate, 1-2 parts of a cross-linking agent TAC, 2-3 parts of chlorotributylstannane tributyltin chloride, 14-18 parts of nylon 12, 6-9 parts of 582-2 amino resin, 0.5-1.0 part of simethicone, 3-4 parts of nano brick slag powder, 1-2 parts of potassium tetraborate, 7-9 parts of an auxiliary, 120-130 parts of cresol and 100-120 parts of xylene. A product is high in paint hardness and cannot turn yellow, a paint film is waterproof, chemically resistant, good in ageing resistant, firm in adhesion, not prone to spalling, convenient to use and small in adhesion pollution, the adherence is improved, and the problems that withstand voltage of a copper-clad aluminum electromagnetic wire does not reach the standard as well as wear resistance, salt mist resistance, severe environment resistance and the like do not reach the standard all the time are solved.

Description

technical field [0001] The invention relates to a wire enamel, in particular to a 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 resistance, salt s...

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.
