Detailed ways

The present utility model will be described in further detail below in conjunction with the specific embodiments.

In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the It is described, rather than indicated or implied, that the device or element referred to must have a particular orientation, be constructed and operate in a particular orientation, and therefore should not be construed as limiting the invention.

In the description of the present invention, it should be noted that, unless otherwise expressly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense. Specific circumstances understand the specific meanings of the above terms in the present invention.

As shown in FIG. 1 and FIG. 2 , the present embodiment provides a composite board that is not easily deformed, including a solid wood core layer 3 , the upper surface and the lower surface of the solid wood core layer 3 are respectively compounded with a balance layer 2 , and two layers of balance layers 2 The outer surfaces are all compounded with a finishing layer 1. That is, from top to bottom, a five-layer composite structure of facing layer 1, balance layer 2, solid wood core layer 3, balance layer 2, and facing layer 1 is formed in sequence. The whole of the composite board is a cuboid, and its length and width can be extended according to specific needs.

The solid wood core layer 3 is provided with a plurality of upper stress grooves 4 extending downward 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 upward 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. There is an included angle between the upper stress slot 4 and the lower stress slot 5 , and a stress hole 6 is formed at the intersection of the upper stress slot 4 and the lower stress slot 5 . The functions of the upper stress slot 4 and the lower stress slot 5 are to release the stress when the non-deformable composite plate is subjected to stress, and the stress on both surfaces of the composite plate can be relieved. The stress hole 6 further relieves the stress of the composite plate. Therefore, the composite board is not easily deformed during production and use.

Further, the angle between the upper stress slot 4 and the lower stress slot 5 is 90°, and the upper stress slot 4 and the lower stress slot 5 are vertical.

The upper stress slot 4 is parallel to the length direction of the solid wood core layer 3, the lower stress slot 5 is parallel to the width direction of the solid wood core layer 3, the spacing between the adjacent upper stress slots 4 is 20mm-50mm, and the distance between the adjacent lower stress slots 5 is 20mm-50mm. The spacing between them is 80mm-100mm.

The thickness of the solid wood core layer 3 is h, the depth of the upper stress groove 4 is a, and the depth of the lower stress groove 5 is b, where 1/2h<a≤2/3h, 1/2h<b≤2/3h. In this way, while ensuring the overall strength of the solid wood core layer 3, the stress can be released to prevent deformation under force.

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

The width of the upper stress slot 4 and the lower stress slot 5 is not greater than 3 mm. If the distance between the upper stress slot 4 and the lower stress slot 5 is too large, the stress cannot be completely relieved, and the number of stress holes 6 is reduced, which cannot prevent deformation.

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

The decorative layer 1 is a stone plastic SPC decorative surface layer. The facing layer 1 includes a wear-resistant resin film, a printed color film, and a stone-plastic SPC backing plate. The material of the wear-resistant resin film includes wear-resistant powder and aluminum oxide. The printed color film is obtained by printing on polypropylene PP film or PVC film. The material of the stone plastic SPC backing plate includes 25% of 25% polymer and 75% of calcium carbonate according to the mass percentage. Wherein, the polymer can be polyvinyl chloride, polypropylene, a mixture of polyvinyl chloride and polypropylene, and the ratio of polyvinyl chloride and polypropylene in the mixture of polyvinyl chloride and polypropylene can be adjusted according to requirements. Since the stone plastic SPC backing plate does not use cross-linking agent, it will not generate formaldehyde, clean and pollution-free, and will not cause damage to the human body.

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

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