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 moisture-resisting and oil-resistant epoxy self-bonding paint for an electromagnetic wire. The moisture-resisting and oil-resistant epoxy self-bonding paint is characterized by being prepared from raw materials in parts by weight (kilogram) as follows: 12-15 parts of E-42 epoxy resin, 10-12 parts of phenolic resin, 8-10 parts of amino resin, 12-15 parts of nylon 12, 2-3 parts of anilino-methyl-triethoxysilane, 3-4 parts of 1,6-hexanediol diacrylate, 1-2 parts of benzoin, 2-3 parts of zinc oxide, 1-2 parts of polyamide wax, 2-3 parts of dicumyl peroxide, 1-2 parts of coconut oil monoethanolamide, 3-5 parts of an ACR (acrylate copolymer) impact resisting agent, 12-15 parts of aluminum oxide, 7-9 parts of an assistant, 80-90 parts of m, p-cresol and 100-120 parts of dimethylbenzene. The process is simple, the production process is stable and easy to control, and the consistency of finished products is improved substantially; the production process is environment-friendly; the epoxy self-bonding paint prepared with the method has excellent oil resistivity and good moisture resistance, and the temperature classification is improved, so that the service lives of the finished products are prolonged; and the bonding strength and the surface smooth finish of a coated wire are improved due to adding of the coupling agent and the assistant.

Description

technical field [0001] The invention relates to an enamelled wire varnish, in particular to a moisture-resistant and oil-resistant electromagnetic wire epoxy self-adhesive varnish meeting the heat resistance requirement of a heat level of 155°C and above 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 th...
