Embodiment 1

[0037] Hexafunctional acrylate modified amino resin 30%

[0038] Hexafunctional Urethane Acrylate 10%

[0039] Bisphenol A epoxy acrylate 10%

[0040] Trimethylolpropane Triacrylate 30%

[0041] 2-Methyl-2-hydroxyester-1-oxyphenylpropane (Darocure 1173 Ciba product) 5%

[0042] Matting Powder (OK 500 Degussa, Germany) 8%

[0043] Al 2 o 3 Powder (KD203 Hangzhou Xinglong) 7%

[0044] Mix the above components in a reaction kettle, heat to a temperature of 50-60°C, stir evenly for 0.5-3 hours, and disperse and emulsify for 0.5-3 hours. After cooling, the UV-curable wear-resistant coating specially used for the density plate of the heat-pressed paper film of the present invention is obtained. The paint was coated on the tinplate plate and the density plate with heat-pressed paper film with a wire bar, and its performance was measured after UV curing. The results are shown in Table 1.

Abstract

An ultraviolet solidified antiwear paint for the surface of high-density board with hot-pressed surficial paper layer contains proportionally acrylate (or methylacrylate) modified amino resin, polyurethane acrylate or polyurethane methylacrylate, epoxy acrylate or epoxy methyl acrylate, acrylate or methylacrylate, optical trigger, antiwear inorganic powder and dulling powder.

Description

technical field [0001] The invention belongs to the photocurable paint in the field of chemical industry, and relates to an ultraviolet light curable wear-resistant paint used for woodware, especially a surface coating layer of a density board that has been heat-pressed with a paper film. Background technique [0002] At present, laminate flooring has been widely used in large quantities. The manufacturing process of laminate flooring is generally as follows: medium density floor (MDF) is hot-pressed with a paper film impregnated with melamine, and covered with a very thin layer of aluminum oxide particles. As reported in US Patent No. 5,654,091, the laminated floor using this process is very rough, easily loses gloss, and has a poor surface effect. The U.S. patent uses a layer of 100um thick thermoplastic film to replace the paper film soaked in melamine. As a result, the surface is very smooth, and a very ideal surface effect is obtained, basically...
