Organosilicon wire enamel with thermal level up to 155 DEG C or above and preparation method of organosilicon wire enamel

Abstract

The invention discloses organosilicon wire enamel with a thermal level up to 155 DEG C or above and a preparation method of the organosilicon wire enamel. The organosilicon wire enamel is characterized by being prepared from raw materials in parts by weight as follows: 13-16 parts of E-44 epoxy resin, 5-8 parts of nano aluminum oxide, 2-3 parts of dimethylaminoethyl methacrylate, 10-12 parts of nylon 12, 10-12 parts of novolac epoxy resin, 5-7 parts of organic silicon resin, 4-6 parts of a titanate coupling agent TMC-TTS, 8-15 parts of m-amino methylamine, 8-10 parts of magnesium hydroxide, 4-5 parts of hexamethylphosphoric triamide, 2-3 parts of dysprosium oxide, 7-9 parts of an assistant, 80-90 parts of m, p-cresol and 100-120 parts of xylene. The organosilicon wire enamel has the advantages as follows: the follow-up coating baking process is easy to control, the molecular weight is uniform, and the consistency is good; peculiar smell is reduced at the normal temperature and during baking; products can be stably stored, the coating process is good, and the surface of a finished product is smooth and uniform; the temperature classification of the finished product is up to 155 DEG C (F level) or above, the hot punching is up to 180 DEG C or above, and the soft breakdown is up to 240 DEG C or above; and the medium resistance is excellent, and the organosilicon wire enamel has excellent adhesiveness.

Description

technical field [0001] The invention relates to a wire enamel, in particular to an organosilicon wire enamel meeting the 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 the production of enameled wire. Enameled wire enamel requires good adhesion, mechanical strength, insulat...

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.
