The invention discloses polyester wire enamel capable of realizing welding-slag-free direct welding and a preparation method of the polyester wire enamel. The polyester wire enamel is characterized by comprising raw materials in parts by weight as follows: 20-24 parts of nylon 11, 12-15 parts of unsaturated polyester resin, 15-18 parts of polyester polyol, 14-18 parts of amino resin, 4-7 parts of triallyl isocyanurate, 3-4 parts of ferrocene, 1-2 parts of urotropine, 1-2 parts of 2-mercaptobenzimidazole, 12-14 parts of mica, 2-3 parts of titanium dioxide, 2-4 parts of isocyanate, 2-3 parts of zinc octoate, 1-2 parts of dibutyltin dilaurate, 7-9 parts of an additive, 120-140 parts of m,p-cresol and 140-160 parts of xylene. After enameled wires are coated with the obtained polyester wire enamel, welding slag is not produced during tin welding.
Description
Technical field
The present invention relates to a kind of wire enamel, especially a kind of straight weldering is without polyester wire enamel of welding slag and preparation method thereof.
Background technology
Enameled wire is a kind of electrical material, and it is the high-strength insulating layer of processing thin layer a circular copper line surface, plays the effect with external insulation.By specification, can be processed into than also thin lousiness line of hair, as thick cotton covered wire as thumb.Enameled wire has good insulation effect and waterproof ability.Aspect electrical equipment application very extensive, as electric motor, generator, water pump, electro-magnet, welding machine, household electrical appliance, cableless communication, loud speaker, tg, transformer etc.Wire enamel is the necessary insulating material of producing enameled wire, wire enamel requires to have good tack, physical strength, insulating property, resistance toheat, wear resisting property, salt spray resistance and adverse environment resistant performance etc., but there is thermotolerance, wear no resistance in common wire enamel, insufficient strength, heat-resisting level be lower than the problems such as 120 ℃, is difficult to meet the requirement of varying environment.Need to improve the formula of wire enamel and production technique, further improve the performance of enamel-cover paint, reduce its production cost.
Summary of the invention
Object of the present invention is just to provide a kind of straight weldering without polyester wire enamel of welding slag and preparation method thereof, to overcome the deficiencies in the prior art.
