Embodiment 1

[0010] A kind of UV-water-based spray matte topcoat of the present invention, its component and its weight ratio are: the component of this topcoat and its weight ratio are: 40% UV water-based resin 85%, defoaming 0.1% of agent, 1.0% of dispersant, 1% of matting agent, 3% of film forming agent, 1% of initiator, 0.5% of wetting agent, 0.5% of thickener, 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, BASF, BAYER, etc.; the defoamer is not Containing silicone polymer solution, polyether siloxane copolymer 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, BYK190 or their mixtures produced by BYK; the initiators are aromatic ket...

Embodiment 2

[0018] Another kind of UV-water-based spray finish paint 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: The components of the topcoat and their weight proportions are: 40% UV water-based resin 75%, defoamer 0.5%, dispersant 2%, matting agent 5%, film forming agent 5%, initiator 3% , 1% wetting agent, 1% thickener, and the balance is water.

Abstract

The invention discloses an UV (Ultraviolet)-water-based spray coating matte finish which comprises the following components by weight percentage: 75%-85% of 40% UV water-based resin, 0.1%-0.5% of defoamer, 1.0%-2% of dispersing agent, 1%-5% of flatting agent, 3%-5% of film-forming agent, 1%-3% of initiator, 0.1%-1% of wetting agent, 0.5%-1% of thickening agent and the balance of water, wherein the 40% UV water-based resin is polyurethane acrylic resin, or modified epoxy acrylic resin or a mixture thereof; and the flatting agent is an inorganic powder (silicon dioxide). The UV-water-based spray coating matte finish disclosed by the invention is fine in surface film, low in glossiness, soft and natural; the formed film is resistant to scratch, and also capable of highlighting the natural textures of wood; and therefore, a beautiful, scratch-resistant protective layer can be formed on wood products such as wood furniture and a wood floor; and as a result, lasting protection is formed on the surface of the wood furniture and the wood floor.

Description

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