[0024] Unless otherwise defined, the technical terms or scientific terms used in this specification and claims shall have the common meanings understood by persons having ordinary skills in the technical field to which the present invention belongs.

[0025] refer to Figure 1 The embodiments of the present utility model provide a decorative wood composite board, which is mainly used in scenes with decorative requirements, and some embodiments do not exclude the application in scenes with decorative requirements and load-bearing requirements.

[0026] The decorative wood composite panel comprises a first plywood surface layer 1, a first density board color layer 2, a core layer 3, a second density board color layer 4 and a second plywood surface layer 5 which are arranged and compositely formed along the thickness direction; the first plywood surface layer 1 and the second plywood surface layer 5 are respectively located on two surface layers of the decorative wood composite panel; the color of the side surface of the core layer is different from the color of the side surface of the first density board color layer 2 and / or the color of the side surface of the second density board color layer 4; the side surfaces of the first plywood surface layer 1, the first density board color layer 2, the core layer 3, the second density board color layer 4 and the second plywood surface layer 5 are correspondingly flush and exposed.

[0027] The "thickness direction" refers to the direction perpendicular to the board surface of the decorative wood composite board. In the present invention, "arranged along the thickness direction" is used to indicate the order of multiple layers. Specifically, in some embodiments, the first plywood surface layer 1, the first density board color layer 2, the core layer 3, the second density board color layer 4 and the second plywood surface layer 5 are arranged in sequence, and two adjacent layers are directly composited. In some other embodiments, the overall arrangement is according to the first plywood surface layer 1, the first density board color layer 2, the core layer 3, the second density board color layer 4 and the second plywood surface layer 5, wherein other wooden boards are compounded between at least one group of adjacent layers, for example, a built-in composite structure is arranged between the first plywood surface layer 1 and the first density board color layer 2, and / or, a built-in composite structure is arranged between the second plywood surface layer 5 and the second density board color layer 4; wherein the built-in composite structure is compounded by a built-in plywood and a built-in density board color layer, preferably, the built-in plywood is arranged closer to the first density board color layer 2, and correspondingly, the built-in density board color layer is closer to the first plywood surface layer 1, so that the layering of the side of the decorative wood composite board is better.

[0028] The first plywood surface layer 1 and the second plywood surface layer 5 are arranged at two surfaces to provide color and / or pattern for the surface of the decorative wood composite board. At the same time, the first plywood surface layer 1 and the second plywood surface layer 5 are made of plywood, which has good bending resistance and ensures the good mechanical properties of the decorative wood composite board. The core layer 3 can be used as a decorative layer to play a decorative role. It should be noted that in some embodiments, the core layer 3 can also be used as a supporting layer to play a supporting role, and is used in occasions where both decorativeness and load-bearing properties are required as auxiliary. The first density board color layer 2 and the second density board color layer 4 have colors, and since the color of the side of the core layer 3 is different from the color of the side of the first density board color layer 2 and / or the color of the side of the second density board color layer 4, the side of the decorative wood composite board visually has a color layering effect, which plays a decorative role. Therefore, the decorative wood composite board has an artistic sense and a self-decorating effect after being exposed. There is no need to use a seal to seal the side of the decorative wood composite board separately, so there is no problem of cracking of the edge strips and the resulting poor user experience. Accordingly, the utility model reduces production costs due to the elimination of the edge sealing process.

[0029] It should be noted that the exposed side of the decorative wood composite board provided in the embodiment of the utility model can be directly used as a finished product or further processed as an intermediate product in actual application, and an environmentally friendly transparent varnish is coated on the exposed side. The environmentally friendly transparent varnish is a coating composed of resin as the main film-forming substance and a solvent. It is coated on the side of the decorative wood composite board and forms a smooth film after drying. The varnish can penetrate well into the surface of the wood, thereby enhancing the adhesion of the varnish. Compared with the existing edge strips, it is more solid and not easy to fall off.

[0030] In some embodiments, the core layer 3 is used as a decorative layer, and a wood board is used. The thickness of the core layer 3 is the same as the thickness of the first plywood surface layer 1, and the thickness of the first plywood surface layer 1 is the same as the thickness of the second plywood surface layer 5. Of course, in other embodiments, the thickness of the first plywood surface layer 1 is different from the thickness of the second plywood surface layer 5, and the thickness of the core layer 3 is the same as the thickness of the first plywood surface layer 1 or the same as the thickness of the second plywood surface layer 5, which is also within the scope of protection of the utility model. The decorative wood composite panels in these embodiments can be used in decorative parts of houses.

[0031] Different from the above-mentioned embodiments, in some other embodiments, the core layer 3 is used as a supporting layer, and a solid wood board is used. The thickness of the core layer 3 is twice the thickness of the first plywood surface layer 1, and the thickness of the first plywood surface layer 1 is the same as the thickness of the second plywood surface layer 5. Of course, in some other embodiments, the thickness of the first plywood surface layer 1 is different from the thickness of the second plywood surface layer 5, and the thickness of the core layer 3 is twice the thickness of the first plywood surface layer 1, or twice the thickness of the second plywood surface layer 5, which is also within the protection scope of the present utility model. In these embodiments, the decorative wood composite board has good mechanical properties and environmental protection performance, and can be used in scenes where decoration is the main function and load-bearing is secondary.

[0032] In some embodiments, the first plywood surface layer 1 and the second plywood surface layer 5 have the same thickness, which not only makes the side view more beautiful, but also makes the decorative wood composite board as a whole bear more uniform forces at all positions when subjected to forces. Of course, in some other embodiments, as an alternative, the first plywood surface layer 1 and the second plywood surface layer 5 are made of boards with different thicknesses.

[0033] In some embodiments, the first plywood surface layer 1 and the second plywood surface layer 5 have the same number of layers, such as three, five or seven layers, so that the side of the decorative wood composite board looks more beautiful. Of course, in some other embodiments, as an alternative, the first plywood surface layer 1 and the second plywood surface layer 5 can also be made of boards with different numbers of layers.

[0034] The first plywood surface layer 1 and the second plywood surface layer 5 can be produced by using existing plywood production technology, by planing thin slices from solid wood segments and then gluing them together, which will not be described in detail in the present utility model.

[0035] The first density board color layer 2 and the second density board color layer 4 are made of density board or a composite structure made of density board. The first density board color layer 2 and the second density board color layer 4 are made of sawdust, resin and pigment. Of course, other auxiliary materials can be added during the production process. The production process of the density board can be realized by the existing technology, which will not be described in detail here. The density board can be any color, so after adding the density board color layer, there are more color options compared to the various types of boards used in the existing technology, and it is no longer limited to the color of the wood itself. In specific applications, the appropriate color can be selected according to the needs.

[0036] In some embodiments, the first density board color layer 2 and the second density board color layer 4 have the same thickness, so that the side of the decorative wood composite board has a symmetrical aesthetic. Of course, in some other embodiments, the first density board color layer 2 and the second density board color layer 4 use boards of different thicknesses, which is also within the scope of protection of the utility model.

[0037] In some embodiments, the first density board color layer 2 is a single-layer density board, and when viewed from the side of the decorative wood composite board, the first density board color layer 2 has only one color. In other embodiments, the first density board color layer 2 is formed by compounding a plurality of density boards to form a multi-layer structure, and the adjacent density boards have different colors, so that the decorative wood composite board has more forms of visual effects; when selecting a method of compounding a plurality of density boards, the color of the density board is understood in a broad sense, and may include primary colors; in addition, the thickness of each density board may be the same, further enhancing the beauty of the side, and of course, the solution of using different thicknesses of each density board is also within the protection scope of the present utility model.

[0038] In some embodiments, the second density board color layer 4 is a single-layer density board, and when viewed from the side of the decorative wood composite board, the second density board color layer 4 has only one color. In other embodiments, the second density board color layer 4 is formed by compounding a plurality of density boards, and the colors of adjacent density boards are different, so that the decorative wood composite board has more forms of visual effects; when selecting a method of compounding a plurality of density boards, the color of the density board is understood in a broad sense, and may include primary colors; in addition, the thickness of each density board may be the same, further enhancing the beauty of the side surface. Of course, the solution of using different thicknesses of each density board is also within the protection scope of the present utility model.

[0039] It should be noted that the first density board color layer 2 and the second density board color layer 4 do not affect each other in terms of the number of layers, thickness and color, and can be arbitrarily matched. For example, both can adopt a single-layer density board, the colors can be the same or different, the thickness can be the same or different, and for another example, both can adopt a form of a composite of several density boards, the number of layers can be the same or different, the thickness of each density board of the two can be the same or different, the total thickness of each of the two can be the same or different, and the color matching of the two can be the same or different. When applied specifically, a suitable combination can be selected for production or use according to actual needs. As a preferred embodiment, the first density board color layer 2 and the second density board color layer 4 adopt the same multilayer structure and are symmetrically arranged relative to the core layer. As another preferred embodiment, the first density board color layer 2 and the second density board color layer 4 adopt a single board with the same thickness and the same color.

[0040] In some embodiments, adjacent layers are laminated by glue, specifically, the first plywood surface layer 1 and the first density board color layer 2 are laminated by glue, the first density board color layer 2 and the core layer 3 are laminated by glue, the core layer 3 and the second density board color layer 4 are laminated by glue, and the second density board color layer 4 and the second plywood surface layer 5 are laminated by glue. Transparent glue can be used as the laminated glue.

[0041] In some embodiments, since the first density board color layer 2 and / or the second density board color layer 4 are formed by compounding multiple density boards, the compounding process here can also be performed by compounding with transparent glue.

[0042] When producing decorative wood composite panels, the first plywood surface layer 1, the first density board color layer 2, the core layer 3, the second density board color layer 4 and the second plywood surface layer 5 are arranged in sequence, and the adjacent layers are directly compounded. The first plywood surface layer 1, the first density board color layer 2, the core layer 3, the second density board color layer 4 and the second plywood surface layer 5 can be coated with glue and stacked, and then formed by a composite process to obtain a prefabricated product; the prefabricated product is cut to obtain the decorative wood composite panel. For the embodiment in which the first plywood surface layer 1, the first density board color layer 2, the core layer 3, the second density board color layer 4 and the second plywood surface layer 5 are arranged as a whole, and other wooden boards are compounded between at least one group of adjacent layers, the built-in composite structure can be pre-compounded and then compounded with the first plywood surface layer 1, the first density board color layer 2, the core layer 3, the second density board color layer 4 and the second plywood surface layer 5; or the built-in density board color layer, the built-in plywood, the first plywood surface layer 1, the first density board color layer 2, the core layer 3, the second density board color layer 4 and the second plywood surface layer 5 can be directly coated with glue and arranged in a required order and compounded together.

[0043] Among them, for any of the above solutions, when the first density board color layer 2 and / or the second density board color layer 4 adopts a multi-layer structure, they can be pre-made through a glue compounding process, and then the decorative wood composite board can be produced in the above manner.

[0044] In addition, the terms "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, a feature defined as "first", "second", etc. may explicitly or implicitly include one or more of the features.
