Description

Technical Field

[0001] This invention belongs to the field of building decoration materials technology, and relates to flooring, and more particularly to a three-layer solid wood composite antibacterial and waterproof flooring and its preparation process. Background Technology

[0002] To enhance market competitiveness and meet consumers' high demands for waterproof flooring, the common practice is to spray edge sealant on the tongue and groove of the wood planks, apply paint to the bottom surface, and then apply a film to the tongue and groove and the bottom surface; or to apply paint to the bottom surface, seal the tongue and groove with wax, and then apply a film to the bottom surface to prevent the wood surface from contacting water and achieve a waterproof effect.

[0003] However, the above-mentioned flooring still has the following problems: First, the paint applied to the tongue and groove joints cannot completely cover the wood surface and can only play a partial role in waterproofing; second, the tongue and groove joints are sealed with wax, and when the tongue and groove joints are joined together, the wax film is damaged and falls off due to movement and installation knocking, resulting in an unsatisfactory waterproofing effect. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the present invention aims to provide a three-layer solid wood composite antibacterial and waterproof flooring. By adjusting the flooring structure and locking mechanism, the mutual restraint between the layers is increased, thereby improving the waterproof stability of the three-layer flooring.
