Embodiment 1

[0011] A UV-water-based spray primer according to the present invention, its components and their weight proportions are: 40% UV water-based resin 85%, defoamer 0.5%, dispersant 1.0%, matting agent 1%, film forming agent 3%, initiator 1%, wetting agent 0.5%, thickener 0.5%, and the balance is water. Among the above components: the UV-water-based resin is polyurethane acrylic resin, or modified epoxy acrylic resin or polyester acrylic resin or their mixtures, such as those produced by CYTEC, BAYER, BASF, etc.; the defoamer is not Containing silicone polymer solution, polyacrylic acid polymer or their mixture, such as TEGO901W, TEGO902W or their mixture produced by Tego Company; the dispersant is high molecular weight block copolymer solution, alkoxy ammonium salt block Copolymer solutions or their mixtures, such as BYK180 and BYK190 produced by BYK or their mixtures; the initiators are aromatic ketones, benzoin and their derivatives or their mixtures, such as IRGACURE500 and 11...

Embodiment 2

[0018] Another kind of UV-water-based spraying primer of the present invention is a semi-matt paint, compared with embodiment 1, only the weight proportion is different, and the components and weight proportions thereof of this semi-matte paint are: 40% UV water-based resin 75%, defoamer 0.2%, dispersant 2%, matting agent 2%, film forming agent 5%, initiator 3%, wetting agent 1%, thickener 0.5%, The balance is water.

Abstract

The invention discloses an ultraviolet (UV)-waterborne spraying primer. The primer comprises the following components in percentage by weight: 75-85 percent of 40 percent UV water-base resin, 0.1-0.5 percent of a defoaming agent, 1.0-2 percent of a dispersing agent, 1-2 percent of a delustering agent, 3-5 percent of a film-forming agent, 1-3 percent of an initiator, 0.5-1.5 percent of a wetting agent, 0.5-1 percent of a thickening agent and the balance of water, wherein the 40 percent UV water-base resin is polyurethane acrylate resin or a modified epoxy acrylate resin or a mixture thereof; the delustering agent is inorganic powder. The primer is high in base material wettability, low in gloss, soft and natural, and the formed film can make the natural texture of wood prominent; the primer can also be colored, so that the coating effect is diversified, and a good foundation is laid for coating of finish paint.

Description

technical field [0001] The invention relates to a UV-light curing wood coating, in particular to a glossy or matte UV-water-based spray primer. 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, and industrialized production has been formed. With the development of painting technology and the improvement of people's living standards, people's aesthetics are becom...
