Abstract

The invention discloses heat-resistant alcohol-soluble self-adhesive paint for a self-adhesive insulated winding wire and a preparation method thereof. The heat-resistant alcohol-soluble self-adhesive paint is prepared from 10-15 parts by weight (kg) of ethyl methacrylate, 12-14 parts by weight (kg) of butyl acrylate, 4-6 parts by weight (kg) of zirconia, 7-9 parts by weight (kg) of ethylene glycol monophenyl ether, 12-15 parts by weight (kg) of nylon12, 50-55 parts by weight of isophorone, 30-35 parts by weight (kg) of benzyl alcohol, 12-15 parts by weight (kg) of E51 epoxy resin, 8-10 parts by weight (kg) of montmorillonite, 3-4 parts by weight (kg) of mercaptopolysiloxane, 3-5 parts by weight (kg) of isocyanate, 12-15 parts by weight (kg) of polyoxymethylene, 12-13 parts by weight (kg) of naphthenic oil, 3-4 parts by weight (kg) of petroleum resin, 10-12 parts by weight (kg) of dipentaerythritol hexaacrylate, 7-9 parts by weight (kg) of an assistant, 80-90 parts by weight (kg) of a mixture of m-cresol and p-cresol, and 40-50 parts by weight (kg) of xylene. The preparation method has simple processes. The outer surface of a three-layer insulated winding wire is coated with the heat-resistant alcohol-soluble self-adhesive paint so that a self-adhesive three-layer insulated winding wire is obtained. A frameless coil prepared from the self-adhesive three-layer insulated winding wire has the advantages of high voltage resistance, good high-frequency performances, good thermostability and good wear resistance.

Description

technical field [0001] The invention relates to an enameled wire varnish, in particular to a heat-resistant alcohol-soluble self-adhesive varnish for self-adhesive insulated winding wires 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 a...
