Amino resin wire enamel and preparation method thereof

Abstract

The invention discloses amino resin wire enamel which is prepared from raw materials in parts (kilogram) by weight as follows: 5-8 parts of trimellitic anhydride, 10-12 parts of maleic anhydride. 14-16 parts of hexamethylene diacrylate, 15-19 parts of E-12 epoxy resin, 6-8 parts of polyacrylamide, 12-15 parts of amino resin, 3-4 parts of sodium hexametaphosphate, 15-18 parts of polyvinylidene chloride, 6-10 parts of m-xylylenediamine, 15-20 parts of activated calcium carbonate, 12-15 parts of nylon 12, 7-9 parts of auxiliaries, 90-100 parts of cresol and 100-120 parts of dimethylbenzene. The preparation method is simple, the cost is low, and the prepared wire enamel has good heat resistance, refrigeration resistance, abrasion resistance and oil resistance.

Description

technical field [0001] The invention relates to a wire enamel, in particular to an amino 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 resis...

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.
