Odorless and wear-resisting smooth UV (ultraviolet) matt finish paint coating and preparation method thereof

Abstract

The invention belongs to the field of coatings and particularly relates to an odorless and wear-resisting smooth UV (ultraviolet) matt finish paint coating and a preparation method thereof. The odorless and wear-resisting smooth UV matt finish paint coating comprises components in percentage by weight as follows: 25%-50% of hexa-functional polyurethane acrylate prepolymers, 15%-50% of trifunctional modified polyurethane acrylate prepolymers, 15%-50% of acrylate monomers, 1%-10% of a photoinitiator, 0.2%-2% of a wetting dispersant, 0.2%-1% of a leveling agent, 0.2%-0.5% of a defoaming agent and 1%-15% of a matting agent. According to the odorless and wear-resisting smooth UV matt finish paint coating, the technical problems that a pungent smell is left, wetting of the matting agent is difficult, matting is difficult, a paint film is prone to floating and the like after curing of a conventional UV matt finish paint coating are solved, and meanwhile, the defect of crispness of the paint film caused by improvement of the wear resistance of the conventional UV matt finish paint coating is overcome.

Description

technical field [0001] The invention belongs to the field of coatings, and in particular relates to a clean, odor-resistant and wear-resistant silky UV matte finish coating and a preparation method thereof. Background technique [0002] UV light-curing coating (also known as UV-curing coating) refers to a new type of coating that can be cross-linked and cured in a short period of time under ultraviolet light. Because of its energy-saving, environmentally friendly, economical and efficient features, It meets the environmental protection requirements of human beings for environmental issues and VOC emission control. It has been recognized by the world's coating industry and most management agencies, and is widely used in different fields such as wood, paper, plastic, and metal.

AI Technical Summary

Problems solved by technology

[0003] Many domestic paint manufacturers have introduced UV light-curing coatings. Some invention patents disclose UV wood matte varnishes that have no residual irritating odor after curing, which solves the problem of clean odor after curing, but does not solve the problem of UV matte topcoats. The matting agent has poor wettability, poor fluidity, soft hardness and poor wear resistance of the paint film after coating and curing, and the paint film is prone to blooming and other disadvantages.

There are also some invention patents disclosing clean odor and wear-resistant UV light-curing coating technology, but they only involve UV-curing varnish coatings, not UV matte topcoat coatings.

[0004] Among the existing patented inventions, there are many technologies that refer to odor-free and wear-resistant UV coatings, but there are no patents related to odor-free, wear-resistant, and silky UV matte topcoat coatings. Silky UV matte finish coatings have poor odor and abrasion resistance, difficult wetting properties of matting agents, difficult matting and easy blooming of the paint film, and other technical problems cannot provide a good solution.
