Abstract
The invention discloses polyurethane wire enamel which is characterized by being prepared from raw materials in parts by weight (kilogram) as follows: 12-15 parts of polyurethane resin, 10-15 parts of E-12 epoxy resin, 1-2 parts of monobutyltin oxide, 2-3 parts of montmorillonite powder, 6-9 parts of pentaerythritol hexaacrylate, 3-4 parts of 1,6-hexamethylene diisocyanate, 12-15 parts of nylon 12, 2-3 parts of tree ash, 1-2 parts of 2-ethyl-4-methylimidazole, 3-4 parts of jade powder, 7-9 parts of an assistant, 100-120 parts of xylene and 100-120 parts of m, p-cresol. According to a preparation method, defects of poor flexibility, small adhesive force and smaller DV (diameter and velocity) values of a polyurethane enamelled wire produced with a conventional method are overcome, and the adherence and the heat resistance are improved. According to the polyurethane wire enamel prepared with the method, the margin of a wire coating process is large, and the wire coating velocity is high. The method can be used for preparing novel 180-grade polyurethane wire enamel with high DV values.
Description
Technical field
The present invention relates to a kind of wire enamel, especially a kind of polyurethane wire enamel 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.
