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, smo

Example Embodiment

[0034] Example 1 is UV wood laser roller coating bright white topcoat, so no matting agent is added to the formula; Example 2 is UV wood laser roller coating semi-matte white topcoat, so a small amount of matting agent is added to the formula; Example 3 is a full matt white topcoat for UV wood laser roller coating, so a matting agent is added to the formula.

[0035] The raw material components and weight formulas (unit: kg) of Examples 1 to 3 are shown in Table 1.

[0036]

[0037] Table 1

[0038] Among them, the urethane acrylic acrylate, modified epoxy acrylic resin, functional monomer trimethylolpropane triacrylate (TMPTA), tripropylene glycol diacrylate (TPGDA), 1,6-ethylene glycol Diacrylate (HDDA), 13-hydroxyethyl methacrylate (HEMA), propylene oxide neopentyl glycol diacrylate (2PO-NPGDA), and UV white paste, matting powder is used as a component in the coating system 膜物。 Membrane. Modified epoxy acrylic resin has high hardness, chemical resistance and high gloss, as well ...

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.
