[0045] (1) The hardening and wear-resistant primer mainly functions to improve the hardness and wear resistance of the coating.

[0049] The present utility model has the following several technical innovation points and beneficial effects:

[0050] (1) The technical innovation point of the present utility model mainly lies in the technical improvement and innovation of the topcoat coating. By using the material structure of the roller-coated film-pressed UV transparent odorless high stain-resistant, high yellowing-resistant, odorless super semi-gloss topcoat coating + the UV-3D simulation skin-like texture super semi-gloss transfer top layer, which are separated and synthesized with each other, it solves the problems of poor stain resistance, yellowing resistance, low surface hardness, low impact resistance of traditional skin-feeling coating products, as well as the need to use special topcoats and coating equipment, and the complex process resulting in high product cost.

[0051] The technical principle is to use a UV-3D simulated texture film pressing mold (roller press line contact type) to copy or reproduce the mechanical or physical surface appearance micro-texture of simulated skin texture on the mold surface with digital technology, transfer or transfer, reproduce or copy it to the topcoat on the surface of the board, giving the board topcoat a special skin-feeling surface feel or tactile effect with fluff, tiny bumps or wrinkles on the surface, thereby achieving the skin texture and super-sub-gloss on the surface of the board while inheriting and retaining the high surface performance and low-cost technical characteristics and features of the topcoat, such as high hardness, high stain resistance, high yellowing resistance, and high impact resistance, and overcoming the pain points of the traditional skin-feel coating itself, which has an unbalanced surface performance in the molecular structure, as well as low surface performance such as stain resistance, yellowing resistance, and impact resistance, as well as high cost;

[0052] (2) In addition, another technical innovation of the present invention is that the starting point for improving surface performance and reducing cost and increasing efficiency of product coating is shifted from the topcoat with a higher price and a single cost reduction point to the various functional primers of the primer and midcoat with a lower price and a more cost reduction point. Among the various functional primers, primer coatings with a clean odor, high hardness, high yellowing resistance and high impact resistance are applied. While the topcoat achieves cost reduction and efficiency improvement and surface performance improvement, the product performance and cost are further optimized, so that the overall performance improvement and cost reduction and efficiency improvement can achieve the maximum beneficial effect.

[0053] (3) Another beneficial effect of the present invention is the improvement of production efficiency. Compared with the traditional skin-feel super matte coated board, the coating efficiency can be increased from 12-15m / min to 15-20m / min;

[0054] (4) The product of the utility model has been tested and verified, and the test data results show that: the surface hardness of the paint film can be improved from 2B of the traditional skin-feel super matte coated board to above HB, which is improved by two levels; the surface pollution resistance is improved from level 4 to level 5; the surface impact resistance is improved from level 3 to level 1; the surface yellowing resistance is improved from the color difference value ≤6.0 to the color difference value ≤3.0; the odor-free level is improved from ≤2 to ≤1;

[0055] (5) In addition, the product of the utility model, after testing and verification of actual production costs, compared with the traditional skin-feeling super matte coated board, the cost reduction of its coating decorative surface is about 3-6 yuan / m2. According to the commonly used format specifications of 1220*2440mm, each double-sided furniture board can achieve a cost reduction effect of 18-36 yuan / sheet, which has good cost reduction and efficiency improvement effects and low cost characteristics.
