[0018] The following description is only used to disclose the utility model so that those skilled in the art can implement the utility model. The embodiments described below are only for example, and those skilled in the art can think of other obvious variations. The basic principles of the utility model defined in the following description can be applied to other embodiments, variations, improvements, equivalents, and other solutions that do not deviate from the spirit and scope of the utility model.

[0019] [Example 1]

[0020] A metal wood composite panel, such as Figure 1 , including a metal plate layer 13, a plastic layer 12, a metal plate layer 13 and a solid wood veneer layer 11 arranged in sequence, and each layer is bonded together by glue, wherein the thickness of the plastic layer 12 is ≥ half of the total thickness, and the thickness of the solid wood veneer layer 11 is ≤1mm.

[0021] The metal plate layer 13 can be made of other materials such as aluminum plate, iron plate, etc., preferably aluminum, which has the advantages of being light and easy to cut.

[0022] The plastic layer 12 is made of polyethylene, but other polymer materials may also be used.

[0023] By arranging the metal plate layer 13 and the plastic layer 12, the board has better anti-deformation, anti-cracking and waterproof effects, and also makes the fireproof performance of the board reach Class B. The outer solid wood veneer layer 11 makes the board have a better aesthetics, and by adjusting the thickness, it has the touch of wood while avoiding affecting the anti-deformation, waterproof and fireproof effects.

[0024] Preferably, the plastic layer 12 has a thickness of ≥1 mm.

[0025] Preferably, the surface of the solid wood cortex layer 11 has wood grain, and the wood grain can be produced by printing, embossing and other methods.

[0026] Optionally, the outer surface of the outer metal sheet layer 13 is provided with a protective film.

[0027] Embodiment 2, based on embodiment 1, a solid wood veneer layer is also provided outside the outer metal plate layer, that is, a solid wood veneer layer is provided outside the metal plate layers on both sides, which is suitable for the situation where the board is directly used and both sides of the board are exposed.

[0028] A sheet material, such as Figure 2 , including the metal-wood composite board 1 and the filling layer 2 in the above-mentioned embodiment 1. If a protective film is provided on the metal-wood composite board 1, it needs to be removed. The filling layer 2 is located between two groups of metal-wood composite boards. This board has better waterproof and fireproof properties. The thickness of the filling layer 2 is adaptively set according to needs. The filling layer uses wood or foaming material, and the foaming material includes foaming board, foaming glue, polyurethane and other materials.

[0029] Preferably, a plurality of cavities 21 are provided in the filling layer. The cavities 21 can be formed by cutting the plate after forming or by forming the plate together with the plate. The provision of the cavities 21 can reduce the weight of the plate and increase the sound insulation effect of the plate.

[0030] Furthermore, the cavity 21 can be arranged inside the filling layer, or can be arranged near the metal-wood composite board, which is convenient for processing and can also reduce the amount of glue used. Optionally, the cavity 21 can be arranged as a square groove or a dovetail groove, and the dovetail groove can ensure the contact area between the filling layer and the metal-wood composite board 1. Optionally, the cavity 21 can be arranged as a horizontal long groove or an inclined long groove, and the inclined long groove can have a longer length than the horizontal long groove within a certain length.

[0031] In this embodiment, two rows of holes 21 are arranged, and the two rows of holes are arranged in an alternating manner. The holes 21 can be arranged intermittently or through-type. Optionally, the holes 21 can be filled with sound-absorbing materials or reinforcing materials (such as metal strips) or a connecting structure of adjacent panels can be installed.
