AI Technical Summary

Problems solved by technology

However, the flame retardant effect of the existing flame retardant enameled wire is average, and the flame retardant grade is low. The enameled wire will produce a lot of thick smoke and molten drops during the burning process, and the drops can continue to ignite the surrounding combustible substances. Increase the degree of fire; and thick smoke is not conducive to people's escape from the fire and fire rescue, which poses a great security threat to human production, life and the environment
Therefore, the existing technology has the problems of poor flame retardant effect and low flame retardant grade.

Abstract

The invention discloses a composite flame retardant for flame-retardant enamelled surface coating and its preparation method and application, comprising the following components in parts by weight: hydroxyethyl acrylate, 20-45 parts; isophorone diisocyanate, 45-90 parts; 10-(2,5-dihydroxy N,N-dimethylacetamido)-10-hydrogen-9-oxa-10-phosphaphenanthrene-10-oxide, 5-12 parts ; Vinyltriethoxysilane, 10-20 parts; Melamine cyanurate, 5-10 parts; Solvent, 60-120 parts; Catalyst, 0.03-0.05 parts. The preparation method is to add each component into the container one by one, stir at 30-40°C for 1-2 hours; then raise the temperature to 80-100°C, stir and react for 10-20 hours to obtain a flame-retardant lacquer coating Composite flame retardants are used. The invention has the characteristics of being able to effectively improve the flame retardant effect and increase the flame retardant grade.

Description

technical field [0001] The invention relates to an enameled wire topcoat, in particular to a composite flame retardant for a flame-retardant enameled topcoat and a preparation method and application thereof. Background technique [0002] Enameled wire refers to a bare copper (aluminum) wire as the wire core, usually rectangular or round, softened by annealing, and then painted and baked several times. It is a kind of electromagnetic wire (ie, winding wire). Electromagnetic effects are generated in the form of windings to realize the conversion of electric energy and magnetic energy, motion control and signal transmission functions, and generally have four major properties: mechanical properties, chemical properties, electrical properties and thermal properties. As one of the main technical supporting raw materials in the fields of electric power, motors, electrical appliances, home appliances, electronics, communications, transportation, and power grids, it plays a huge role...
