UV woodware laser roller-coating white finish coat and preparation method thereof

Abstract

The invention discloses UV woodware laser roller-coating white finish coat. The UV woodware laser roller-coating white finish coat comprises the following components in percentage by weight: 32%-40% of monomers, 5%-8% of aliphatic polyurethane acrylic resin, 30%-40% of modified epoxy acrylic resin, 4%-6% of a photoinitiator and 10%-15% of a UV white sizing agent. After mechanical laser roller-coating construction, the UV woodware laser roller-coating white finish coat disclosed by the invention is great in coating amount, quick in leveling, good in whiteness covering power, flat and free of roller marks on coating surface, so that the coated film has excellent mirror-surface effect; meanwhile, the UV woodware laser roller-coating white finish coat is convenient to construct, scratch-resistant, high in hardness, free of smell, good in adhesive force, good in hand feeling, and the like. Meanwhile, coat can be saved (coating amount being about 30-50 grams per square meter), so that factory cost can be effectively lowered and product quality and working benefits are improved.

Description

technical field [0001] The invention relates to a UV wood coating, in particular to a UV wood laser roller coating white finish coating and a preparation method thereof. Background technique [0002] At present, the roller coating method commonly used in the field of UV wood coatings is mechanical roller coating with smooth surface ordinary rubber. The problems of this method are that the coating amount is small, the fullness is poor, and the surface effect is not good and uneven, showing a pockmarked surface. As a result, in view of the above phenomenon, the laser roller coating mechanical coating machine with laser engraving grooves and related supporting laser roller coatings have been launched on the market. The surface effect of this laser roller coating coating after laser roller coating mechanical coating can Comparable to flow coating and spray coating, the surface of the coating film is very plump, smooth, and presents a mirror effect.

Problems solved by technology

[0002] At present, the roller coating method commonly used in the field of UV wood coatings is mechanical roller coating with smooth surface ordinary rubber. The problems of this method are that the coating amount is small, the fullness is poor, and the surface effect is not good and uneven, showing a pockmarked surface. As a result, in view of the above phenomenon, the laser roller coating mechanical coating machine with laser engraving grooves and related supporting laser roller coatings have been launched on the market. The surface effect of this laser roller coating coating after laser roller coating mechanical coating can Comparable to flow coating and spray coating, the surface of the coating film is very plump, smooth, and presents a mirror effect. Patent cases CN102952455, patent case CN103627300 and patent case CN102140306 are laser roller coatings for UV transparent systems. There is no mature UV coating in the market. Wood laser roller coating white products, while ordinary UV wood roller coating white topcoat cannot completely wet into the groove of the laser engraved laser roller, and after the laser roller roller coats the board, the paint cannot be quickly spread and leveled on the board. Therefore, the surface can not achieve the smooth and smooth effect of the mirror surface at all, and the white finish of UV wood roller coating on the market has the characteristics of poor whiteness, poor adhesion, and poor hand feeling.
