Problems solved by technology

However, due to the poor surface flatness, transparency and plumpness of ordinary UV-curable paints, and limited wear resistance, the surface of wooden furniture, wooden floors and other wooden products is prone to scratches or scratches. In order to avoid this situation, usually Consumers should be

Example Embodiment

[0010] Example 1

[0011] The UV-curing topcoat of the present invention can be divided into two types: semi-matte and gloss. The components of the gloss paint and their weight ratio are: 100% UV resin 60%, defoamer 0 . 5%, dispersant 1%, filler 5%, initiator 5%, leveling agent 1%, anti-settling agent 1%, the balance is monomer. Among the above components: UV-resin is polyurethane acrylic resin, or modified epoxy acrylic resin or their mixture, such as those produced by CYTEC, SARTOMER, Changxing, Miki, etc. Monomers are: acrylic esters, modified acrylic esters or their mixtures, such as those produced by CYTEC, SARTOMER, Changxing, and Sanmu. The defoamer is free of silicone polymer solutions, polyacrylic acid polymers or their mixtures, such as BYK055, BYK080A or their mixtures produced by BYK. The dispersant is a high molecular weight block copolymer solution, a modified acrylic block copolymer solution or their mixture, such as BYK164, BYK103 or their mixture produced by BY...

Example Embodiment

[0018] Example 2

[0019] Another UV-curable topcoat of the present invention is a semi-matte paint. Compared with Example 1, only the weight ratio is different. The components and weight ratio of the semi-matte paint are: 100% UV resin 50%, defoamer 0.5%, dispersant 2%, filler 10%, initiator 8%, leveling agent 1%, anti-settling agent 1.5%, matting agent 5%, the balance is monomer.

Example Embodiment

[0020] Example 3

[0021] Another UV-curing topcoat according to the present invention is a gloss paint. Compared with Example 1, only the weight ratio is different. The components of the varnish and their weight ratio are: 100% UV resin 70%, defoamer 0.5%, dispersant 1%, filler 5%, initiator 3%, leveling agent 1%, anti-foaming agent Settling agent 1%, the balance is monomer.

Abstract

The invention discloses an ultraviolet-curtain coating finish. The finish comprises the following components in percentage by weight: 50 to 70 percent of 100 percent ultraviolet resin, 0.1 to 0.5 percent of defoaming agent, 1.0 to 2 percent of dispersing agent, 5 to 10 percent of filler, 3 to 8 percent of initiator, 0.1 to 1 percent of leveling agent, 1 to 1.5 percent of settling agent, and the balance of monomers, wherein the 100 percent ultraviolet resin is polyurethane acrylic resin, or modified epoxy acrylic resin or a mixture thereof; the monomers are acrylate monomers, modified acrylate monomers or a mixture thereof; and the filler is inorganic powder. The ultraviolet-curtain coating finish has high surface evenness, good transparency and high plumpness; and the formed film has high flexibility and scraping resistance, and can form a scraping-resistant protective layer on the surfaces of wood products such as wood furniture and wood floors, so as to durably protect the surfaces of the wood furniture and the wood floors.

Description

technical field [0001] The invention relates to a UV-light-curing wood coating, in particular to a semi-matte or glossy UV-curing topcoat. Background technique [0002] UV is the English abbreviation of Ultraviolet (ultraviolet), and UV paint is ultraviolet light curing paint. Ordinary wood boards, silicon-calcium boards and other boards are painted with UV paint, and then dried by a UV light curing machine to form stone boards. They have bright surface treatment, bright color, strong visual impact, wear resistance, and strong chemical resistance. Long service life, no discoloration, easy to clean, is an ideal plate maintenance treatment process. The surfaces of existing wooden furniture, wooden floors and other wood products all adopt UV paint, that is, UV curing paint maintenance treatment process. However, due to the poor surface flatness, transparency and plumpness of ordinary UV-curable paints, and limited wear resistance, the surface of wooden furniture, wooden floor...
