Abstract

The invention relates to an ultraviolet cured vacuum spraying colored paint, which comprises the following components in percentage by weight: 20 to 40 percent of resin, 20 to 40 percent of acrylic compound monomer, 2 to 7 percent of polymeric dispersant, 5 to 9 percent of photoinitiator and 20 to 30 percent of toner, wherein the resin is epoxy acrylate, polyester acrylic resin or a mixture of the epoxy acrylate and the polyester acrylic resin mixed in any ratio, and the polymeric dispersant is a dicarboxylate solution of a polymer of which themolecular weight is between 4,000 and 25,000 and the pigment affinity group is an amine group. The ultraviolet cured vacuum spraying colored paint of the invention overcomes the shortcoming that the conventional solvent type colored paint is heavy in pollution and is not environment-friendly and the shortcoming that the UV spraying varnish cannot be made into solid color paint, and has the advantages of high curing speed, high production efficiency, environment friendliness and the like.

Description

technical field [0001] The invention relates to an ultraviolet light curing paint, in particular to an ultraviolet light curing vacuum spray paint. Background technique [0002] Currently, solvent-based coatings are mainly used for solid-color coatings on handrails, railings, and corner lines on the market. Their VOC content is high, and a large amount of organic solvents are generated during the coating, which not only causes waste of resources, air Pollution, and will be slowly released after penetrating porous wood, causing long-term harm to indoor occupants. [0003] Vacuum spraying is a method of rapid coating on profiled materials, using modified wax to coat the surface of the material. However, the wax coating film cannot be used as a solid color paint, and has disadvantages such as poor heat resistance, poor weather resistance, poor chemical resistance, and unsightly coating film. UV coatings are low-VOC coatings, which meet the current needs of resource conservati...
