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.

Abstract

The invention discloses a polyester modified wire enamel, which is made of the following raw materials by weight parts(kg): 12-15 of amino resin, 12-14 of polyester resin (EL-1000H), 2-3 of ethylene bis stearamide, 6-9 of tetramethylethylenediamine, 12-16 of nylon 11, 1-2 of tungsten boride, 5-8 of 2-amino-2-methyl-1-propanol, 5-8 of attapulgite, 5-8 of diamino diphenyl ether, 10-12 of glycerol, 12-15 of ethylene glycol, 2-3 of straw ash, 2-3 of attapulgite, 30-35 of N-methylpyrrolidine, 1-2 of a promoter Na-22, 7-9 of an assistant, 90-100 of m, p-cresol, and 100-120 of dimethylbenzene. The preparation method provided by the invention is simple, and is low in cost. The prepared wire enamel has the advantages of good heat resistance and freeze resistance, and good wear resistance and oil resistance.

Description

Technical field [0001] The invention relates to an enameled wire paint, in particular to a polyester modified enameled wire paint and a preparation method thereof. Background technique [0002] Enameled wire is an electrical material. It is a thin, high-strength insulating layer processed on the surface of a round copper wire to insulate from the outside world. According to the specifications, it can be processed into a woolen 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, welding machines, household appliances, wireless communications, speakers, telegraphs, transformers, etc. Enameled wire paint is a necessary insulating material for the production of enameled wire. Enameled wire paint requires good adhesion, mechanical strength, insulation performance, heat resistance, abrasion resista...
