Abstract

The invention provides a net-flavor full-matt ultraviolet-curing coating, which is prepared from the following components by weight percentage: 20-35 percent of ultraviolet curing resin, 40-57 percent of reactive acrylate monomers, 8.0-14 percent of organic matt powder, 0.8-4.0 percent of wax powder, 3.0-10 percent of photoinitiator, 0.2-0.5 percent of defoamer, 0.2-1.0 percent of flatting agent and 0.5-2.0 percent of wetting dispersant. The method is as follows: ultraviolet curing modified polyester acrylic resin with 90-98 percent of solid content is adopted to obtain the moderate hardness of paint film; and three kinds of reactive monomers are combined, the total content percentage of the monomers in the coating is reduced, the adhesive force, the hardness, the hand feeling, the glossiness and the fullness of paint film are increased, and the problems of odor, luster and the like before and after construction are solved. The selected resin is resin with a low functional group, and the reactive monomers are N-contained monomers. The coating has the adhesive force to various base materials, has low odor and is full-matt.

Description

technical field [0001] The invention belongs to the field of coating compositions, and in particular relates to a coating composition containing organic macromolecules and a preparation method thereof. Background technique [0002] Due to the advantages of short recoating time, high production efficiency, and environmental protection, UV-curable coatings have developed rapidly. However, nitro coatings, unsaturated resin coatings, and polyurethane coatings are all inferior to UV light-curing coatings due to their environmental protection, efficiency, and production costs. Especially in terms of environmental protection, it is also inferior to UV light-curing coatings. Analysis and experimental testing of the formulations commonly used in the existing UV photocuring coating technology, combined with the experimental data of the market, can summarize the understanding of the regularity, that is, a formula composed of a variety of acrylic compounds, produced during the photocur...
