Abstract

The invention relates to a light-curing colored paint. The light-curing colored paint is technically characterized by comprising the following components in percentage by weight: 0.2 to 8 percent of light amine-producing agent, 0.5 to 10 percent of amine proliferation agent, 5 to 30 percent of acetoacetic ester compound, 30 to 65 percent of acrylate light-curing resin, 10 to 40 percent of acrylate activated thinner, 0.1 to 8 percent of photoinitiator and 4 to 8 percent of pigment. The light amine-producing agent contained in the system generates amine catalysts under ultraviolet irradiation, further catalyzes to start the amine-producing proliferation reaction of the amine proliferation agent, rapidly generates massive amines in a coating and automatically spreads to the whole coating system to generate amines along regional chemistry. Therefore, a crosslinked curing film is formed, and an invisible region on the surface or at the bottom of a film layer can be rapidly cured.

Description

technical field [0001] The invention relates to the technical field of organic coatings, in particular to a light-curing colored paint that can be quickly cross-linked and cured by ultraviolet light irradiation. Background technique [0002] Industrial fields such as coatings, inks, adhesives, and polymer composite materials generally involve the cross-linking and polymerization of polymer materials to improve the mechanical properties and environmental tolerance of the materials, so that the materials have a certain protective effect and service life, and endow certain decorative. Traditional cross-linking polymerization methods mainly include free radical polymerization cross-linking, isocyanate / polyol cross-linking, anhydride cross-linking, amine cross-linking, etc., generally based on thermal reaction mechanism. This causes the coating formulation system to be sensitive to factors such as ambient temperature and moisture. The formulation with a long storage life often h...
