Description

Technical Field

[0001] This utility model relates to the field of flooring, and in particular to a novel decorative solid wood composite flooring. Background Technology

[0002] Engineered wood flooring uses veneers of varying thicknesses (made from high-grade hardwoods or precious tree species) as the surface layer, plywood made from interwoven solid wood veneers as the base material, and is coated with high-performance, highly wear-resistant, and environmentally friendly UV-cured flooring paint. It is widely used in the home building materials industry.

[0003] Currently, high-grade hardwoods or precious tree species are becoming increasingly scarce in the market, and many countries have begun to formulate a series of laws and regulations to strengthen the protection of rare tree species in forest resources. At the same time, the market also needs to meet the demands of high-end consumers for their home environments, which brings us new considerations. To achieve the decorative effect of high-grade hardwoods or precious tree species on the surface of engineered wood flooring with low-grade hardwood veneers, the industry often uses film transfer printing to achieve this.

[0004] Film transfer printing is a finishing process that uses a PET film with wood grain and color to transfer the wood grain and color onto the surface veneer of engineered wood flooring through heat transfer. The resulting engineered wood flooring has uniform wood grain and color, but the natural wood texture is completely replaced. Even if the texture of low-grade hardwood is printed as that of high-grade hardwood or precious tree species, there will still be problems with the distortion of the surface texture of the engineered wood flooring and the limited decorative effect.

[0005] Therefore, we need to design a new type of veneer engineered wood flooring to solve the above problems. Utility Model Content

[0006] The existing methods of decorating engineered wood flooring using film transfer printing suffer from problems such as distorted surface texture and limited decorative effect. The purpose of this invention is to solve these problems by providing a novel type of engineered wood flooring with a decorative finish.

[0007] According to one aspect of this utility model, a novel veneer engineered wood flooring is provided, comprising a substrate, a panel, and a veneer layer arranged sequentially from bottom to top. The upper surface of the panel is brushed to form a brushed texture, the depth of which is 0.05–0.1 mm. The veneer layer comprises a white primer layer, a transfer layer, and a topcoat layer sequentially disposed on the panel. This utility model enhances the three-dimensional effect of natural textures by creating a brushed texture on the upper surface of the panel; it covers natural color differences on the panel surface by applying a white primer layer; it restores the natural texture of the panel surface by setting a transfer layer on the white primer layer; and it protects the transfer layer by applying a topcoat layer. This novel veneer engineered wood flooring features natural textures, uniform color, good decorative effect, and also enhances the texture grade of the panel. This invention achieves a high-grade effect on low-grade panels (such as oak and birch) by brushing the surface of the panel, applying a white primer to cover color differences, and using roller transfer printing. Compared with PET film transfer solid wood composite flooring, this new type of decorative solid wood composite flooring can more realistically reproduce natural textures, has a better three-dimensional effect, and better visual characteristics.

[0008] In some embodiments, the substrate is made of multiple layers of solid wood veneers bonded together by cross-lamination and hot pressing, and the face panel is an oak or birch veneer with a natural wood grain on the upper surface. Therefore, the substrate has a reasonable and stable structure, which can effectively eliminate internal stress in the flooring and prevent cracking and deformation.

[0009] In some embodiments, the transfer layer is formed by roller printing the wood grain of precious tree species onto the upper surface of a white primer layer. Thus, roller transfer printing can restore the natural texture of the panel surface and also enhance the texture grade of the panel.

[0010] In some embodiments, the white primer layer comprises, sequentially disposed on the panel, a water-based white primer layer, a UV adhesion primer layer, a first UV scratch-resistant primer layer, and a second UV scratch-resistant primer layer. Thus, by applying a white primer layer to the panel, natural color variations on the panel surface can be concealed, and the abrasion resistance of the paint surface can be enhanced.

[0011] In some embodiments, the coating amount of the water-based white primer layer is 10 g / m², the coating amount of the UV adhesion primer layer is 10 g / m², the coating amount of the first UV scratch-resistant primer layer is 12 g / m², and the coating amount of the second UV scratch-resistant primer layer is 12 g / m².

[0012] In some embodiments, an intermediate coating layer is provided between the transfer layer and the topcoat layer. This intermediate coating layer comprises, sequentially disposed on the transfer layer, a first UV-scratch-resistant intermediate coating layer, a UV-low-odor intermediate coating layer, a UV-colored intermediate coating layer, a UV-abrasion-resistant intermediate coating layer, and a second UV-scratch-resistant intermediate coating layer. Therefore, by providing an intermediate coating layer on the transfer layer, the abrasion resistance and service life of the flooring can be improved.

[0013] In some embodiments, the coating amount of the first UV scratch-resistant intermediate coating layer is 12 g / m², the coating amount of the UV low-odor intermediate coating layer is 8 g / m², the coating amount of the UV coloring intermediate coating layer is 8 g / m², the coating amount of the UV abrasion-resistant intermediate coating layer is 8 g / m², and the coating amount of the second UV scratch-resistant intermediate coating layer is 12 g / m².

[0014] In some embodiments, the topcoat layer includes a UV matte topcoat layer and a UV odor-free topcoat layer sequentially disposed on the intermediate coat layer. Thus, by providing a topcoat layer on the intermediate coat layer, the transfer layer can be protected.

[0015] In some embodiments, the coating amount of the UV matte topcoat layer is 6 g / m², and the coating amount of the UV odor-free topcoat layer is 6 g / m².

[0016] In some embodiments, the panel and the substrate are bonded together by adhesive. Thus, the panel and the substrate can be tightly bonded together using adhesive.

[0017] The beneficial effects of this utility model are as follows:

[0018] 1. This utility model enhances the three-dimensional effect of natural textures by creating a brushed texture on the surface of the panel; it covers natural color differences on the panel surface by applying a white primer layer; it restores the natural texture of the panel surface by applying a transfer layer on the white primer layer; and it protects the transfer layer by applying a topcoat layer on top of the transfer layer. This new type of veneered solid wood composite flooring features natural textures, uniform colors, excellent decorative effects, and also elevates the texture grade of the panel.

[0019] 2. This utility model achieves a high-grade effect on low-grade panels (such as oak and birch) by brushing the surface of the panel, applying white primer to cover color differences, and roller transfer printing. Compared with PET film transfer solid wood composite flooring, this new type of decorative solid wood composite flooring can more realistically reproduce natural textures, has a better three-dimensional effect, and has better visual characteristics.

The veneer layer comprises a white primer layer 3, a transfer layer 4, and a topcoat layer 6, sequentially disposed on the panel 2. The topcoat layer 6 is a transparent varnish layer. This invention enhances the three-dimensional effect of the natural texture by creating the brushed texture 7 on the upper surface of the panel 2; it covers natural color variations on the surface of the panel 2 by applying the white primer layer 3; it restores the natural texture of the panel 2 by placing the transfer layer 4 on the white primer layer 3; and it protects the transfer layer 4 by applying the topcoat layer 6. This novel veneer engineered wood flooring features natural texture, uniform color, excellent decorative effect, and also enhances the texture grade of the panel 2. This invention achieves a high-grade effect on low-grade panels (such as oak and birch) by brushing the surface of the panel 2, applying white primer to cover color differences, and using roller transfer printing. Compared with PET film transfer solid wood composite flooring, this new type of decorative solid wood composite flooring can more realistically reproduce natural textures, has a better three-dimensional effect, and better visual characteristics.

[0028] The substrate 1 is made of multiple layers of solid wood veneer, cross-laminated and hot-pressed together. The substrate 1 has a reasonable and stable structure, effectively eliminating internal stress and preventing cracking and deformation of the flooring. In this application, the panel 2 is pre-sanded, resulting in a smooth, burr-free surface that improves the flatness of the flooring. Panel 2 is an oak or birch veneer with natural wood grain on its upper surface. Oak or birch veneers are low-grade hardwoods with rough textures and color variations. Panel 2 is bonded to the substrate 1 with adhesive. The adhesive tightly bonds panel 2 and substrate 1 together.

[0029] The transfer layer 4 is formed by printing the wood grain of precious tree species onto the upper surface of the white base coat layer 3 using a roller printing method. The transfer layer 4 is a printing layer with UV ink, and the ink content is 3g / ㎡. Roller transfer printing can restore the natural texture of the surface of panel 2 and also enhance the texture grade of panel 2.

[0030] The white primer layer 3 comprises, sequentially disposed on the panel 2, a water-based white primer layer 31, a UV adhesion primer layer 32, a first UV scratch-resistant primer layer 33, and a second UV scratch-resistant primer layer 34. By applying the white primer layer 3 to the panel 2, natural color differences on the surface of the panel 2 can be concealed, and the abrasion resistance of the paint surface can be enhanced. The coating amount of the water-based white primer layer 31 is 10 g / m², the coating amount of the UV adhesion primer layer 32 is 10 g / m², the coating amount of the first UV scratch-resistant primer layer 33 is 12 g / m², and the coating amount of the second UV scratch-resistant primer layer 34 is 12 g / m².

In this application, the surface of the middle lacquer layer 5 needs to undergo a sanding process to improve the surface smoothness of the middle lacquer layer 5.

[0032] The topcoat layer 6 comprises a UV matte topcoat layer 61 and a UV odor-free topcoat layer 62 sequentially disposed on the intermediate coat layer 5.
