Wild jujube shell wood floor capable of removing formaldehyde and preparation method

The invention relates to a wild jujube shell wood floor capable of removing formaldehyde and a preparation method, and belongs to the technical field of wood floors. The wild jujube shell wood floor comprises an upper layer, a middle layer and a bottom layer. The upper layer, the middle layer and the bottom layer are bonded together through a binding agent, relative to the positions of the upper layer and the bottom layer, the middle layer has extrusion and extension to enable one side face of the wood floor to form a tenon or a mortise, and a carbon layer in a zigzag shape is arranged on the lower bottom surface of the bottom layer; and a folded fiber mesh is embedded in the end surface, with the tenon or the mortise of a single-layer side face, of the wild jujube shell wood floor. The floor-preparing technology comprises the steps that wild jujube shells are grinded, mixed slurry is prepared and pressed, a carbonated layer is handled and shaped, and the wood floor is formed to be a finished product.
