Problems solved by technology

Chinese patent CN 1782300A discloses a wall decoration board and its manufacturing method. The method is to bond asbestos cement boards of the same size on the foam board made of polystyrene to form a composite board. Protect and fix with an adhesive, and then coat the putty layer, sealing primer layer, intermediate paint layer and topcoat layer on the outer surface and surrounding surface of the composite board in order to form a wall decoration board, but because the wall Surface decorative panels use traditional coatings, which have slow drying speed, low production efficiency, and large site occupation
Chinese patent CN 1182724A discloses a light magnesium cement board cured by electron radiation coating and its processing technology. The product is based on magnesium cement board and is cured by electron radiation after brushing the coating on its surface. The process is simple and environmentally friendly. Energy saving, fast curing speed, and high production efficiency, but the investment in electron beam curing equipment is high, and the operating cost of the equipment is high, so it is difficult to popularize and use

Abstract

The invention belongs to the construction material decorative board field, in particular to a UV-curable color wall decorative board produced by coating the surface with UV-curable coatings and a preparation method thereof. A UV-curable putty layer is coated on the surface of the wall decorative board substrate, a UV-curable closed primer layer is coated on the surface of the UV-curable putty layer, a UV-curable color topcoat layer is coated on the surface of the UV-curable closed primer layer, and a polypropylene or polyethylene protective film is coated on the surface of the UV-curable color topcoat layer. A UV-curable white primer layer is positioned between the UV-curable closed primer layer and the UV-curable color topcoat layer. The UV-curable wall decorative board of the invention has the advantages of high timber intensity, good weatherability, good environmental protection ability, rich colors, thick paint film, high rigidity, high scratching resistance, cleaning convenience, and non-inflammability, compared with the existing commonly used wall decorative boards, the invention has better decorative and protective effects.

Description

technical field [0001] The invention belongs to the field of decorative panels for building materials, in particular to an ultraviolet-curable colored wall decorative panel produced by coating the surface with an ultraviolet-curable coating (UV coating for short) and a preparation method thereof. Background technique [0002] At present, with the increasing number of high-rise buildings and the increasing luxury of various interior decorations, the country has higher and higher requirements for environmental protection, energy saving and fire prevention of buildings. Therefore, various thermal insulation composite materials and fireproof materials have appeared one after another. There are fiber-reinforced cement boards, fiber-reinforced calcium silicate boards, fiber-reinforced magnesium oxide boards, lightweight magnesium chloride cement boards, magnesite boards, gypsum boards, etc. as exterior or interior wall decoration. The current common construction technology is to i...
