Abstract

The invention relates to a high-temperature-resisting lacquered wire lacquer composition based on modified polyaryletherketone and a preparation method thereof. The lacquered wire lacquer composition contains the following ingredients by weight percent: 10 to 45 percent of modified polyaryletherketone, 30 to 70 percent of solvent, 10 to 60 percent of diluent, 1 to 10 percent of lubricating agent, 0.1 to 2.0 percent of flatting agent, and the sum of the weight percent is 100 percent. The solid content of the high-temperature lacquered wire lacquer composition is 15 to 45 percent. The high-temperature lacquered wire lacquer composition is excellent in heat resistance and can meet the national standard of 240-grade lacquered wire lacquer.

Description

technical field [0001] The invention relates to a high-temperature-resistant enameled wire enamel composition based on modified polyaryletherketone, which provides a good enameled surface for cables and meets the national standard of grade 240 enameled wire enamel. Background technique [0002] Enameled wire, also known as magnet wire, is composed of bare wire and insulating paint film covering it, and is widely used in power transmission of electromagnetic coils, industrial engines and other devices. The performance of enameled wire depends largely on the performance and quality of enameled wire paint. Enameled wire varnish is a kind of insulating varnish for special purposes. At present, electric motors around the world are developing towards small size and high power. The coil will generate a lot of heat during use, so the heat resistance of insulating materials Level requirements are also constantly increasing. Especially with the development of high and new technologi...
