Problems solved by technology

However, there is a serious phenomenon of oxygen inhibition in the existing UV curing system. Oxygen inhibition refers to the phenomenon that free radicals are consumed due to the presence of oxygen in the free radical photopolymerization system, which affects the polymerization reaction.
When the photopolymerization system is cured in the air, the oxygen in the air will make the photo-cured surface not completely cured and sticky, which seriously affects the overall performance of the material after photo-curing, especially the large volume shrinkage after curing affects the adhesion and hardness. And other issues
The photoinitiators commonly used in the existing UV curing, such as 1173, etc., due to the slow curing speed, further aggravate the occurrence of oxygen inhibition

Abstract

The invention relates to the field of paint, in particular to fast-drying type ultraviolet curing paint. The fast-drying type ultraviolet curing paint is prepared from components in percentage by weight as follows: 20%-25% of fatty acid modified bisphenol-A epoxy acrylate, 17%-30% of bifunctional aliphatic polyurethane acrylic resin, 35%-45% of active monomers, 0.5%-1% of a photoinitiator, 0.5%-2.5% of a functional agent and the balance of a diluent. The novel photoinitiator is adopted and matched with corresponding resin and monomers, so that the paint has higher gel content, strength and adhesion after photocuring.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a quick-drying ultraviolet light curing paint. Background technique [0002] UV curing is a polymer material in which the photosensitive resin system undergoes polymerization and crosslinking under the irradiation of ultraviolet light to form a three-dimensional network. UV curing technology is known as green technology, which has the advantages of energy saving, environmental protection, high efficiency and multi-function. With the increasing emphasis on environmental protection and the advancement of science and technology, the UV curing market has developed rapidly. UV curing technology has been widely used in coatings, adhesives, inks, electronic packaging, tooth restoration, lithography imaging and biomedicine and other fields. [0003] In the UV curable resin system, the photoinitiator plays a decisive role in the curing of the prepolymer. It is stimulated by ultraviolet radiatio...
