Abstract
The invention provides an enamelled wire coating for an electric appliance and a preparation method thereof. The coating is prepared from the following components in parts by weight: 55-67 parts of dimethylacetamide, 12.5-23 parts of diphenyl methane diisocyanate, 10.8-17.6 parts of polyethylene glycol terephthalate, 2-6 parts of polyamino resin, 3-6 parts of ethyl acetate, 2-5 parts of n-butyl acetate, 3-6 parts of mica, 1-3 parts of aluminum oxide and 3-7 parts of nitrocotton. The coating provided by the invention has excellent electric resistance, chemical resistance and mechanical strength, good insulation and flame retardance, further has a very strong wear-resisting property and is hard to wear, and has a very good protective effect to metal wires.
Description
Technical field
The present invention relates to paint field, relate in particular to a kind of electrical equipment enameled wire coating and preparation method thereof.
Background technology
At present, household electrical appliance in use exist certain potential safety hazard, and especially its electric wire easily leaks electricity and cocks off, and therefore needs to carry out flame-resistant insulation work.Enameled wire coating is a kind of coating that can make to produce between wire and wire good insulation layer, is mainly used in bare copper wire, alloy wire and the ferry-glass covered wire skin of all kinds of wire diameters, to improve and the performance of stable enameled wire.Although existing enameled wire has good fire retardant insulating performance with coating on market, its wear resisting property is poor, and easily wearing and tearing, expose electric wire, produces potential safety hazard.
