[0023] Reference Figs. 1-2 The embodiment of the present application is proposed, the EB coated solid wood composite floor described in the embodiment includes a substrate layer 10, a wood veneer layer 20, a primer layer 30 and an EB wear-resistant coating layer 40 arranged in sequence from bottom to top, the upper surface of the wood veneer layer 20 is provided with a micro-frosted texture pattern 50, and the EB wear-resistant coating layer 40 is formed by EB coating cured by EB electron beam treatment.

[0024] The EB wear-resistant coating 40 is formed by EB coating and EB electron beam curing. The process of the prior art, i.e., UV wear-resistant primer layer 30, roller coating machine, coating amount 16-25 g / m2, UV curing, elastic paint layer 34, roller coating machine, coating amount 12-15 g / m2, UV curing, topcoat layer 35, roller coating machine, 4-7 g / m2, UV curing, is replaced by EB coating-EB electron beam curing. The six processes in the prior art are simplified into two processes. The EB electron beam curing speed is fast, the coating process is reduced, the curing time is reduced, the production time of the solid wood composite floor is greatly reduced, and the production efficiency is improved.

[0025] The EB wear-resistant coating 40 is formed by electron beam curing polyurethane acrylate. The EB wear-resistant coating 40 can form a dense transparent surface, achieve a skin effect, and has excellent wear resistance and hardness. The wear resistance is tested according to GB / T15036.2-2018, and the test value can reach below 0.05 g / 100 r. Compared with the existing paint film, the wear resistance of the solid wood composite floor is greatly improved. The EB wear-resistant coating 40 has strong tensile strength and large tensile breaking rate, so that the EB wear-resistant coating 40 has excellent flexibility, improves the impact resistance of the floor, and the EB wear-resistant coating 40 is not easy to crack, which can effectively replace the wear-resistant thin coating in the prior art.

[0026] Specifically, the primer layer 30 includes a water-based primer layer 31 and a sanding primer layer 32 arranged in sequence from bottom to top. The water-based primer layer 31 is coated and then the sanding primer layer 32 is coated. The sanding primer layer 32 can be effectively attached to the water-based primer layer 31, repair and fill the surface defects of the water-based primer layer 31, ensure the flatness of the subsequent paint film, increase the adhesion of the subsequent coating, ensure the flatness and adhesion of the subsequent coating, avoid the subsequent coating from falling off, and prolong the service life of the EB wear-resistant coating 40, thereby prolonging the service life of the wood floor.

[0027] In this embodiment, the coating amount of the water-based primer layer 31 is 7-9 g / m2, and the coating amount of the sanding primer layer 32 is 12-15 g / m2. The water-based primer layer 31 and the sanding primer layer 32 in this embodiment can be doped with colorants to adjust the color of the solid wood composite floor.

[0028] In this embodiment, the coating amount of the EB coating is 20-27 g / m2. By controlling the coating amount of the EB coating, the thickness of the EB coating is sufficient to ensure the wear resistance and hardness of the EB coating, ensure the service life and appearance of the floor, and avoid the micro-relief texture pattern 50 being covered by the EB wear-resistant coating 40 due to the excessive coating amount of the EB coating.

[0029] As preferred, a decorative layer 60 can be arranged between the primer layer 30 and the EB wear-resistant coating 40, which can be a digital inkjet printing on the primer layer 30 by a digital inkjet printer to form a wood grain printing on the primer surface, combined with the micro-relief texture pattern 50 to further improve the visual effect of the solid wood composite floor. After the formation of the decorative layer, the EB wear-resistant coating 40 is coated and cured.

[0030] Based on the above, the thickness d of the micro-relief texture pattern 50 is 0.1mm≤d≤0.15mm, which presents a solid wood three-dimensional sense and improves wood performance without affecting the wear resistance of the floor.

[0031] Of course, the utility model is not limited to the above-mentioned embodiment, and those skilled in the art can make equivalent transformation or replacement without departing from the spirit of the utility model, and these equivalent transformations and replacements are all included in the range defined by the claims of the present application.
