The present invention will be described in further detail with reference to specific embodiments.

In the description of the present invention, it should be noted that the terms "upper", "lower", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, which are merely for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and operate, and thus, should not be construed as limiting the present invention.

In the description of the present invention, it should be noted that the terms "mounted," "connected," and "connected" are to be construed broadly and their meanings in the present invention may be specifically understood by those skilled in the art unless otherwise specifically defined or limited.

As shown in fig. 1 and fig. 2, the present embodiment provides a composite board that is not easy to deform, which includes a solid wood core layer 3, balance layers 2 respectively compounded on the upper surface and the lower surface of the solid wood core layer 3, and facing layers 1 compounded on the outer surfaces of the two balance layers 2. Namely, a five-layer composite structure of a facing layer 1, a balance layer 2, a solid wood core layer 3, the balance layer 2 and the facing layer 1 is formed in sequence from top to bottom. The whole composite board is a cuboid, and the length and the width of the composite board can be continued according to specific requirements.

The solid wood core layer 3 is provided with a plurality of upper stress grooves 4 extending downwards from the upper surface of the solid wood core layer 3. The solid wood core layer 3 is provided with a plurality of lower stress grooves 5 extending upwards from the lower surface of the solid wood core layer 3. The upper stress grooves 4 are parallel to each other, and the lower stress grooves 5 are parallel to each other. An included angle is formed between the upper stress groove 4 and the lower stress groove 5, and a stress hole 6 is formed at the intersection of the upper stress groove 4 and the lower stress groove 5. The upper stress groove 4 and the lower stress groove 5 are used for releasing stress when the composite board which is not easy to deform is stressed, and stress can be released when two surfaces of the composite board are stressed. And the stress holes 6 further release the stress of the composite board. Therefore, the composite board is not easy to deform in the manufacturing and using processes.

Furthermore, the included angle between the upper stress groove 4 and the lower stress groove 5 is 90 degrees, and the upper stress groove 4 and the lower stress groove 5 are perpendicular.

The upper stress grooves 4 are parallel to the length direction of the solid wood core layer 3, the lower stress grooves 5 are parallel to the width direction of the solid wood core layer 3, the distance between every two adjacent upper stress grooves 4 is 20-50 mm, and the distance between every two adjacent lower stress grooves 5 is 80-100 mm.

The thickness of the solid wood core layer 3 is h, the depth of the upper stress groove 4 is a, the depth of the lower stress groove 5 is b, wherein a is larger than 1/2h and smaller than or equal to 2/3h, and b is larger than 1/2h and smaller than or equal to 2/3 h. So, when can guaranteeing 3 bulk strength of wood sandwich layer, can release stress and warp when preventing the atress.

As a further preferable mode of the above technical solution, the depths of the upper stress groove 4 and the lower stress groove 5 are both 2/3 of the thickness of the solid wood core layer 3.

The widths of the upper stress groove 4 and the lower stress groove 5 are not more than 3 mm. The distance between the upper stress groove 4 and the lower stress groove 5 is too large, so that the stress cannot be completely released, and the number of stress holes 6 is reduced, thereby preventing deformation.

The thickness of the solid wood core layer 3 is 8-15 mm.

The decorative layer 1 is a stone plastic SPC decorative surface layer. The decorative layer 1 comprises a wear-resistant resin film, a printed color film and a stone-plastic SPC backing plate, wherein the wear-resistant resin film, the printed color film and the stone-plastic SPC backing plate are sequentially stacked and assembled and then are subjected to hot pressing to form the decorative layer 1. The material of the wear-resistant resin film comprises wear-resistant powder and aluminum oxide. The printed color film is obtained by printing on a polypropylene PP film or a PVC film. The stone plastic SPC cushion plate comprises 25% of polymer and 75% of calcium carbonate according to mass percentage. The polymer can be polyvinyl chloride, polypropylene, and a mixture of polyvinyl chloride and polypropylene, and the proportion of polyvinyl chloride and polypropylene in the mixture of polyvinyl chloride and polypropylene can be adjusted according to requirements. Because the stone plastic SPC base plate does not use a cross-linking agent, formaldehyde is not generated, and the stone plastic SPC base plate is clean and pollution-free and does not cause damage to human bodies.

The balance layer 2 is a wood veneer, and the fiber length direction of the balance layer 2 is vertical to the fiber length direction of the solid wood core layer 3.

The balance layer 2 is connected with the solid wood core layer 3 in a glued mode, and the balance layer 2 is connected with the veneer layer 1 in a glued mode.
