Problems solved by technology

At present, common UV-curable flame-retardant coatings are generally composed of monomers, reactive diluents, external flame retardants, photoinitiators and additives. It meets the requirements of flame retardant and fire prevention. However, the addition of a large amount of powder not only affects the transparency of the coating film, covering the original pattern color, but also adds a large amount of powder, which affects the penetration of ultraviolet light and reduces the curing speed of the coating.

Abstract

The invention relates to a novel UV flame-retardant coating and a preparation method thereof. The UV flame-retardant coating is prepared from the following raw materials: urethane acrylate, terbium oxide modified undecylenic acid, 3-((hydroxymethyl)amino)-3-oxopropyl phosphonic acid-dimethyl ester, N, N-bis (2-hydroxyethyl)amino methylene phosphonic acid diethyl ester, epoxy acrylate, hyperbranched polyester acrylate, an active diluent, a photoinitiator, a nano filler and an auxiliary agent. According to the UV flame-retardant coating, through the synergistic effect of the raw materials, the UV flame-retardant coating has a relatively high curing speed and also has good flame retardance and stability. The reactive diluent is divided into three parts, the photoinitiator is divided into twoparts, and the reactive diluent and the photoinitiator are added in batches, so that not only is the control convenient, but also the raw materials are mixed more uniformly, the reaction among the rawmaterials is promoted, and the use effect of the UV flame-retardant coating is improved.

Description

technical field [0001] The invention relates to the technical field of coatings, more specifically, it relates to a novel UV flame-retardant coating and a preparation method thereof. Background technique [0002] Fire is one of the frequent disasters in the world today. Applying flame-retardant coatings on the surface of flammable substrates can change the combustion performance of the substrate surface, hinder the rapid spread of fire, prolong the escape or rescue time, and reduce the danger and property loss caused by fire. . [0003] UV-curable coatings use the energy of ultraviolet light to initiate polymerization and cross-linking reactions between low-molecular prepolymers or oligomers in the coating and monomer molecules as reactive diluents, harden, and obtain paint films. UV-cured Compared with traditional coatings, coatings have the advantages of fast curing speed, high film quality, less environmental pollution, and low energy consumption. Therefore, UV-curable c...
