[0003] The surface of existing solid wood composite floor is usually composed of natural wood or wood grain paper, and although these materials look beautiful, they have poor adaptability to environmental changes. The surface layer of natural wood may crack or deform slightly due to factors such as humidity and temperature. Although the bottom layer of solid wood composite floor is generally treated to prevent moisture, the moisture resistance is relatively weak because the surface still contains natural wood or wood grain paper. Although the existing solid wood composite floor has certain wear resistance, it has poor scratch and pressure resistance compared to some high-density composite floor or ceramic tile materials. Especially in the case of heavy objects falling or long-term pressure, the floor is prone to scratches, dents or wear. SUMMARY

[0021] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this utility model. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0022] Example:

[0023] like Figs. 1-3 As shown, a crack-resistant and moisture-proof solid wood composite floor includes a composite floor body 1, and a protective structure layer 2 connected sequentially from top to bottom of the composite floor body 1. The protective structure layer 2 includes an anti-deformation layer 21, a moisture-proof and stabilizing layer 22, an impact-resistant layer 23, an isolation layer 24, a sound-absorbing and moisture-proof layer 25, and a root protection layer 26.

[0024] The anti-deformation layer 21 is made of natural wood veneer or high-hardness impregnated paper, and its surface is coated with a UV-cured anti-permeability coating. After sanding, it forms a smooth and wear-resistant surface. The impact-resistant layer 23 is composed of symmetrically laid horizontal wood veneers. The surface of the veneers is impregnated with hydrophobic resin to form a moisture barrier.

[0025] The isolation layer 24 is an elastic polymer foam material layer, made of EVA, with a thickness of 2mm. It is attached to the bottom of the impact-resistant layer 23 and has excellent elasticity and cushioning performance. It can effectively absorb the energy of the floor when it is impacted by external forces (such as falling heavy objects or stepping pressure), preventing the impact force from being directly transmitted to the underlying structural layer and causing cracking. The sound-absorbing and moisture-proof layer 25 is made of polyethylene or polypropylene film. Its edges are sealed to the tongue and groove of the floor side with hot melt adhesive, eliminating the moisture intrusion path caused by the lack of sealing on the sides of traditional flooring, forming an all-round moisture barrier. (The last sentence appears to be a separate, unrelated section about a root protection layer.) 26 is made of cork composite material or rubber substrate. The surface of the root protection layer 26 is formed into a honeycomb micropore array through molding process. The honeycomb pores can absorb a small amount of moisture that seeps in and release it slowly through air circulation to avoid moisture accumulation. The honeycomb structure disrupts the sound wave transmission path and further reduces noise transmission. The moisture-proof and stabilizing layer 22 is made of high-density oriented fiberboard or multi-layer cross-laminated wood fiberboard. The cross-structure disperses the expansion force after moisture absorption and reduces cracks caused by local stress concentration. Its fiber direction is perpendicular to the surface wood grain direction to counteract the natural shrinkage stress of the wood.
