Abstract
The invention discloses environment-friendly wire enamel which is characterized by being prepared from raw materials in parts by weight (kilogram) as follows: 10-12 parts of nylon 12, 8-10 parts of nylon 11, 12-15 parts of alkyd resin, 2-3 parts of dicumyl peroxide, 2-3 parts of isoprene, 3-4 parts of butadiene, 3-4 parts of N-2-(aminoethyl)-3-aminopropyltrimethoxysilane, 4-5 parts of styrene, 1-2 parts of monobutyltin oxide, 3-4 parts of hexamethylphosphoramide, 3-4 parts of an accelerant DM, 7-9 parts of an assistant, 100-120 parts of m, p-cresol and 80-90 parts of xylene. The environment-friendly wire enamel prepared with the method has excellent heat stability and is convenient to paint in the production process of enamelled wires, and the technological range is wide; and the wire enamel can be excellently demoulded from metal when a coil wound by a wire is formed.
Description
Technical field
The present invention relates to a kind of wire enamel, especially a kind of environment-friendly varnished wire paint paint and preparation method thereof.
Background technology
Enameled wire is a kind of electrical material, and it is at the high-strength insulating layer of a circular copper line surface processing thin layer, plays the effect with external insulation.By specification, can be processed into than hair thin lousiness line also, 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
