Rapidly-cured UV water-based solid color finish paint and preparation method thereof

Abstract

The invention discloses a rapidly cured UV water-based solid color finish paint, which is prepared from the following raw materials in parts by weight: 40 to 80 parts of polyurethane acrylate emulsion, 10 to 20 parts of acrylic emulsion, 1 to 5 parts of coalescing agent, 5 to 10 parts of water, 1 to 5 parts of wetting dispersant, 1 to 2 parts of defoaming agent, 1 to 2 parts of flatting agent, 1 to 10 parts of matting powder, 1 to 2 parts of thickening agent, 3 to 5 parts of photoinitiator, 0.1 to 1 part of mildew preventive and 5 to 10 parts of white paste. According to the invention, the strength of a finish paint film is improved, the bottom layer of the paint is thoroughly cured, the adhesive force of the paint is improved, the coalescing agents with different volatilization rates enable water in the paint to be rapidly volatilized, miliaria bubbles are avoided, the film-forming surface performance is good, and meanwhile, the paint is a novel environment-friendly paint, is high in curing speed, and has the advantages of fingerprint prevention, non-sticking, stain resistance, scratch resistance and the like. Self-repairing is realized; and the production efficiency is high.

Description

technical field [0001] The invention relates to a fast-curing UV water-based solid color topcoat, relates to C09D, and in particular relates to the field of coating compositions. Background technique [0002] As people pay more and more attention to physical health, the solvent-based UV spray topcoat used in the wood coating industry is gradually abandoned, and people begin to turn their attention to water-based coatings, but the interaction between water-based coatings and wood substrates is not sufficient. Well, it cannot satisfy people's pursuit of the performance of wood products. [0003] Chinese invention patent CN202011195315.8 discloses a water-based UV-curable polyurethane coating, which forms a cross-linked three-dimensional network structure through the reaction of polyurethane acrylate and phosphoric acid-modified acrylic resin, which improves the adhesion between the coating and the substrate, but the curing time longer and less productive. Chinese invention p...

[0002]As people pay more and more attention to their health, the solvent-based UV spray topcoat used in the wood coating industry is gradually abandoned by people, and they begin to turn their attention to Water-based coatings, but the interaction between water-based coatings and wood substrates is not good, which cannot meet people's pursuit of wood product performance

[0003] Chinese invention patent CN202011195315.8 discloses a water-based UV-curable polyurethane coating, which forms a cross-linked three-dimensional network structure through the reaction of polyurethane acrylate and phosphoric acid-modified acrylic resin. Improved adhesion between coating and substrate, but longer cure time and lower productivity

Chinese invention patent CN201911165845.5 discloses a light-curable water-based coating resin, which uses water-based polyurethane acrylate and acrylate compounds containing hydrophilic groups to shorten the curing time of the coating, but the hardness of the coating is low. It is easy to be scratched, which shortens the service life of the wood
