AI Technical Summary

Problems solved by technology

[0016] The curing time of the PU paint in the prior art is long, the efficiency is low, and the free TDI is too toxic, easy to cause cancer, harmful to the human body, and the storage conditions of the curing agent are relatively high. Therefore, it is necessary to provide a high curing efficiency, Paints with imitation porcelain effect that are easy to store and relatively safe for users and applicators

Abstract

The invention discloses a glass substrate-use coating with a ceramic imitation effect and a coating method thereof. The glass substrate-use coating with the ceramic imitation effect comprises primer paint, middle paint and surface paint which successively coat a glass substrate. The surface paint comprises the following components: by weight, 20-60 parts of 6-10 function group urethane acrylate C; 10-30 parts of epoxy acrylate, 5-20 parts of high function group UV monomer, 10-20 parts of thermoplastic acrylic resin, 1-8 parts of photoinitiator IRGACURE184, 0.5-2 parts of levelling agent C, and 10-40 parts of solvent C. The glass substrate-use coating with the ceramic imitation effect and the coating method thereof have the advantages of simple and convenient storage, high curing efficiency, no high-toxicity substance, more safety to users and constructors.

Description

technical field [0001] The invention relates to an ultraviolet light curing paint, in particular to a paint with imitation porcelain effect for a glass base material. Background technique [0002] UV curing uses the energy of ultraviolet light to initiate the polymerization and crosslinking reactions between the low-molecular prepolymers or oligomers in the coating and the monomer molecules as reactive diluents to obtain a hardened paint film, essentially through the formation of chemical bonds. Achieve chemical drying. [0003] UV curing technology is divided into free radical curing mechanism, cationic curing mechanism, and free radical-cation hybrid curing mechanism. [0004] UV curing has fast curing speed, high coating quality, less environmental pollution, and low energy consumption. Therefore, it has been more and more widely used in various departments of national production in recent years. [0005] Enamel paint is a kind of color paint. The paint film formed afte...
