High-glossiness flame-retardant UV (Ultraviolet)-curable coating material and preparation method thereof

Abstract

The invention relates to a high-glossiness flame-retardant UV (Ultraviolet)-curable coating material. The high-glossiness flame-retardant UV-curable coating material is prepared from the following raw materials in parts by weight: 35-40 parts of polyester acrylate, 8-11 parts of tetrahydrofuran acrylate, 5-9 parts of ethoxylated nonylphenol acrylate, 3-5 parts of triethyl citrate, 5-8 parts of carbic anhydride, 1-3 parts of nano calcium carbonate, 2-3 parts of benzil dimethyl ketal, 10-15 parts of glycol ethyl ether acetate, 6-9 parts of glycol, 5-9 parts of lauryl acrylate, 4-5 parts of auxiliaries and 5-7 parts of red phosphorus master batch. The UV coating material disclosed by the invention has the advantages of good toughness and difficulty in cracking; through adding nano calcium carbonate, the thermal deformation temperature and stability of the coating material are improved, and the glossiness is good; the coating material further has good flame retardance; due to the auxiliaries, the dispersity of the coating material is improved, the leveling property is good, and a coating layer is smooth and bright.

Description

technical field [0001] The invention belongs to the field of coatings, in particular to a high-gloss flame-retardant UV light-curing coating and a preparation method thereof. Background technique [0002] The advantages of light-curing coatings are short curing time (a fraction of a second to a few minutes), low curing temperature, and low volatile matter, which are energy-saving, resource-saving, pollution-free, and high-efficiency; but there are still some shortcomings, such as free radical type The curing process of light-curing coatings is inhibited by oxygen, poor surface curing, and a series of problems such as yellowing, explosive color, low temperature resistance, high cost, and poor corrosion resistance, all of which need to be continuously improved for different purposes to reduce production costs , to expand the use. Contents of the invention [0003] The purpose of the present invention is to provide a high-gloss flame-retardant UV light-cured coating and its ...
