Abstract

The invention provides polyether-ether-ketone wire enamel and a preparation method thereof. The wire enamel is prepared from the following raw materials including 4,4'-difluorobenzophenone, hexafluoro bisphenol A, hydroquinone, potassium carbonate, tetramethylene sulfone, styrene, 2-hydroxypropyl acrylate, epoxide resin, tributyl phosphate, glycol ether, ethylene-vinyl acetate copolymers, dimethylformamide, silica sol, adipate, neopentyl glycol, sodium pyrophosphate, oleic acid, polyethylene glycol, lecithin, citric acid and magnesium borate. The preparation method comprises the following steps of firstly preparing fluorinated polyether-ether-ketone, and then mixing other ingredients. The polyether-ether-ketone wire enamel prepared by the method has excellent high-temperature-resistant performance, excellent softening breakthrough temperature and breakthrough voltage, uniform enamel film and good toughness.

Description

technical field [0001] The invention belongs to the technical field of wire enamel, and in particular relates to a polyether ether ketone wire enamel and a preparation method thereof. Background technique [0002] Enameled wire is prepared by coating polymer insulating varnish on copper, aluminum, manganese-copper alloy and other metal wires according to a specific production process. This specific insulating varnish is enameled wire varnish. Enameled wire is mainly used as a winding coil, and its function is to realize "electricity"-"magnetic" energy conversion during the working process of components, so enameled wire is also called electromagnetic wire. [0003] The effect of the enameled wire insulating varnish is to create a good insulating layer between the wires in the winding to prevent the flow of current. Enameled wire enamel belongs to electrical insulating varnish. As an electrical insulating varnish, in addition to good dielectric and chemical properties, it ...
