Abstract

The invention discloses ultraviolet cured wood paint and a preparation method thereof. The raw material formula of the ultraviolet cured wood paint comprises the following components in percentage by weight: 30 to 35 percent of modified unsaturated polyester resin, 10 to 20 percent of polyester acrylate, 10 to 15 percent of 1,6-hexanediol diacrylate, 5 to 10 percent oftrimethylolpropane propoxylate triacrylate, 3 to 5 percent of polyhydroxyethyl methacrylate, 0.2 to 0.6 percent of settling agent, 10 to 20 percent of transparent powder, 3 to 6 percent of talcpowder, 0.5 to 1.5 percent of photoinitiator 1, 3 to 5 percent of photoinitiator 2 and 0.2 to 0.6 percent of flatting agent. The ultraviolet cured wood paint can be used as a transparent base coat, is low in cost, simple in preparationmethod and environmentally-friendly, has high transparency, high film performance, high rubbing property and high leveling property, and can create huge economic and social benefit.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to wood varnish technology, in particular to an ultraviolet light curing wood varnish and a preparation method thereof. Background technique [0002] Wood coatings mainly include traditional PU, PE and NC oil-based paints, as well as UV light-curing paints and water-based wood paints developed in recent years. After the appearance of UV light-curing paint, it has developed vigorously in just a few decades due to its fast curing speed and excellent performance, and gradually has a tendency to replace traditional oil-based paint. In the floor and panel furniture industry, UV paint use has become very common. [0003] More than 50% of traditional oil-based paints are volatile organic solvents, which are not only extremely harmful to human health, but also evaporate into the atmosphere after use, causing serious pollution to the atmospheric environment. UV paint almost does not use o...
