Description

Technical Field

[0001] The present application relates to the technical field of ground or floor layers composed of a number of similar components, and in particular to a lightly brushed paint-finished solid wood composite floor. Background Art

[0002] In order to fully display and highlight the natural texture and beauty of the wood of the solid wood composite floor, the brushing process is used to increase the texture and tension of the wood. However, the brushing process uses a wire brush to draw longitudinal grooves on the surface of the floor, especially after fine brushing, and the brushed texture is narrow. Due to the limitations of UV coating materials and process methods, the paint filling of the solid wood composite floor is uneven or not in place during the painting of the solid wood composite floor, which can easily cause the gloss of the surface coating of the solid wood composite floor to be uneven, forming a high and low light difference, affecting the beauty, and even producing a concave and convex structure on the paint surface of the solid wood composite floor, making the solid wood composite floor easy to hide dirt.

[0003] Therefore, there is a structural contradiction between brushing and painting in the surface decoration process of solid wood composite flooring, and one is often neglected while the other is taken into consideration. This field is in urgent need of a method that can fully express the texture and tension of wood through the brushing process, and can also avoid the uneven filling of UV coating or inadequate coating, which makes it easy for dirt to accumulate in the brushed gaps. This is a difficult problem that needs to be solved in the current surface decoration of solid wood composite flooring. Summary of the invention

[0004] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model proposes a lightly brushed paint-finished solid wood composite floor, and the technical solutions adopted include:

[0005] A lightly brushed paint-finished solid wood composite floor comprises a substrate layer and a primer layer and a topcoat layer sequentially arranged on the surface of the substrate layer from bottom to top, wherein the upper surface of the substrate layer is subjected to a brushing process to form a lightly brushed texture, and the depth of the lightly brushed texture is 0.05 to 0.1 mm.

[0006] An embodiment of the utility model adopts a technical solution to solve its technical problem: the primer layer includes an embossed primer composite layer and an adhesion primer layer arranged on the surface of the substrate layer from bottom to top, the embossed primer composite layer includes a plurality of embossed UV primer layers arranged from bottom to top, and each of the embossed UV primer layers is provided with an imitation wood texture matching the shallow brushed texture, and the depth of the imitation wood textures on the plurality of embossed UV primer layers gradually becomes shallower from bottom to top.

[0007] The technical solution adopted by an embodiment of the utility model to solve the technical problem is that the depth of the imitation wood texture on the first embossed UV primer layer is 0.05-0.1 mm.

[0008] An embodiment of the utility model adopts a technical solution to solve the technical problem: the embossed UV primer layer is provided with three layers, and the depths of the imitation wood textures on the three embossed UV primer layers are 0.05-0.1mm, 0.03-0.05mm, and 0.01-0.03mm.

[0009] The technical solution adopted by an embodiment of the utility model to solve the technical problem is: the thicknesses of the three embossed UV primer layers are 0.1-0.15 mm, 0.05-0.1 mm, and 0.03-0.05 mm from bottom to top.

[0010] The technical solution adopted by an embodiment of the utility model to solve the technical problem is: the embossed UV primer layer is formed by curing a water-based UV primer.

[0011] An embodiment of the utility model adopts a technical solution to solve its technical problem: the primer layer also includes an elastic wear-resistant primer layer, a sanding primer layer, a wear-resistant UV primer layer and a matte UV primer layer arranged on the surface of the adhesion primer layer.

[0012] Beneficial effects of the utility model:

[0013] In the present application, the depth of the brushed texture on the substrate layer is limited to 0.05-0.1 mm, so that the depth of the brushed texture on the substrate layer changes from deep to shallow, and then the primer layer is applied to the substrate with shallow brushed texture. After the primer layer is roller-coated and leveled, it is beneficial for the primer layer to fully penetrate into the brushed texture to form a silky paint film.

[0020] Reference Figure 1 , an embodiment of the present application is proposed, the shallow brushed solid wood composite flooring described in this embodiment includes a substrate layer 10 and a primer layer 20 and a topcoat layer 30 arranged on the surface of the substrate layer 10 from bottom to top, the upper surface of the substrate layer 10 is formed with a shallow brushed texture 40 by a brushing process, and the depth of the shallow brushed texture 40 is 0.05 to 0.1 mm.

[0021] In the brushed texture formed by the brushing process of the solid wood composite floor, the depth of the brushed texture is usually about 0.2mm. In this application, the depth of the brushed texture on the substrate layer 10 is limited to 0.05-0.1mm, so that the depth of the brushed texture on the substrate layer 10 becomes shallower, and then the primer layer 20 is coated on the substrate with the shallow brushed texture 40. After the primer layer 20 is roller-coated and leveled, it is beneficial for the primer layer 20 to fully penetrate into the brushed texture to form a silky paint film. In this way, it can not only show rich wood texture, but also make the brushed concave and convex surface of the solid wood composite floor surface become particularly silky without leaving gaps, which solves the problem of dirt and grime on the surface of the solid wood composite floor.

[0022] In the present application, the substrate is pre-sanded, and the specific parameters of the sanding process are 100-180 mesh sanding belt, sanding depth of 0.03-0.08mm, sanding belt speed of 35-40r / min, and board feeding speed controlled at 40m / min. After the sanding process, the surface of the substrate is smooth and burr-free, which is beneficial to improving the surface flatness of the solid wood composite floor.

[0023] Furthermore, in order to further ensure that the primer layer can be fully and evenly filled in the shallow brushed texture 40, the primer layer 20 in this embodiment includes an embossed primer composite layer 21 arranged on the surface of the substrate layer 10, and the embossed primer composite layer 21 includes a plurality of embossed UV primer layers 211 arranged in sequence from bottom to top, and each of the embossed UV primer layers 211 is provided with an imitation wood texture 23 matching the shallow brushed texture 40, and the depth of the imitation wood texture 23 on the plurality of embossed UV primer layers 211 gradually becomes shallower from bottom to top.

[0024] After the wire drawing process is completed on the substrate to form a shallow wire drawing texture 40, the surface of the substrate layer 10 is coated with an embossed UV primer layer 211. After the coating of an embossed UV primer layer 211 is completed, the embossed UV primer layer 211 is embossed and then UV cured. Since the embossed UV primer layer 211 needs to form an imitation wood texture 23 matching the shallow wire drawing texture 40, the embossed texture matches the shallow wire drawing texture 40 when the embossed UV primer layer 211 is embossed. The embossed texture fills the embossed UV primer layer 211 into the shallow wire drawing texture 40, ensuring that the UV coating fills the previous wire drawing texture in place.

[0025] The embossed UV primer layer 211 also has a certain fluidity during the embossing process. After the embossed UV primer layer 211 is embossed, the depth of the imitation wood texture 23 on the surface of the embossed UV primer layer 211 is less than the depth of the shallow brushed texture 40. When each embossed UV primer layer 211 is embossed, the embossed texture is used to fill the texture in the previous embossed UV primer layer 211, and the texture of the embossed UV primer layer 211 is gradually reduced from bottom to top. Therefore, in this embodiment, the embossed UV primer layer 211 is set to several layers, and the depth of the imitation wood texture 23 on several embossed UV primer layers 211 will gradually become shallower from bottom to top. As the depth of the imitation wood texture 23 of several embossed UV primer layers 211 gradually decreases until it disappears, it is beneficial to make the brushed concave and convex surface of the solid wood composite floor surface become particularly smooth without leaving gaps, thereby solving the problem of dirt and grime hiding on the surface of the solid wood composite floor.

[0026] Specifically, the present application adopts a depth of 0.05-0.1 mm for the imitation wood texture 23 of the first embossed UV primer layer 211 , which is consistent with the thickness of the shallow brushed texture 40 , and is conducive to ensuring that the shallow brushed texture 40 is fully filled.

[0027] Based on the above content, the depths of the imitation wood texture 23 on the three embossed UV primer layers 211 are 0.05-0.1mm, 0.03-0.05mm, and 0.01-0.03mm, and the depths of the imitation wood texture 23 on the three embossed UV primer layers 211 change from deep to shallow, and the adhesion primer has excellent leveling properties. Finally, the depth of the imitation wood texture 23 on the third embossed UV primer layer 211 can be filled and leveled under the leveling effect of the adhesion primer layer 22, ensuring that the surface of the solid wood composite floor is silky smooth.

[0028] Furthermore, the thicknesses of the three embossed UV primer layers 211 are 0.1-0.15 mm, 0.05-0.1 mm, and 0.03-0.05 mm from bottom to top, respectively. The thickness of the first embossed UV primer layer 211 is slightly greater than the depth of the shallow brushed texture 40, and the thicknesses of the remaining embossed UV primer layers 211 are slightly greater than the thickness of the previous embossed UV primer layer 211, so that the embossed UV primer layer 211 can fully fill the gaps in the texture.

[0029] In the present application, the embossed UV primer layer 211 is formed by curing a water-based UV primer, which has good leveling properties and excellent adhesion, and is beneficial to improving the surface flatness of the embossed UV primer layer 211 .

[0030] The topcoat layer 30 is formed by a composite of two UV topcoats. In the present application, the primer layer 20 also includes an elastic wear-resistant primer layer 24, a sanding primer layer 25, a wear-resistant UV primer layer 26 and a matte UV primer layer 27 arranged on the surface of the adhesion primer layer 22, thereby improving the wear resistance and life of the paint finish on the surface of the solid wood composite floor.

[0031] Of course, the present invention is not limited to the above-mentioned embodiments, and technicians familiar with the field may make equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications and substitutions are all included in the scope defined by the claims of this application.
