Problems solved by technology

However, the appearance of this composite material is relatively rough, the color is dull, and the shape is stiff, so it is difficult to compete with solid wood panels with natural wood grain.
The existing technology also directly fills a large amount of activated carbon powder between the layers of the composite plate, but this method leads to a decrease in its mechanical properties, easy deformation, and breakage, especially the low strength and loose structure of the carbon powder layer, which is easy to collapse, deform, separate
The carbon powder layer usually requires an adhesive to fix the carbon powder, which will also reduce the contact area between the activated carbon powder and the air and affect the adsorption effect.

Abstract

The invention discloses an adsorption type environment-friendly carbonized wood board and a manufacturing method thereof. Particularly, an adsorption layer is arranged in the board. A blind hole is formed in the adsorption layer and filled with adsorption filler. In comparison with a method of filling activated carbon powder in the prior art, the structure of the adsorption layer is utilized for supporting and limiting the position of the adsorption filler, the overall strength of the board can be effectively improved, and stress deformation, breaking off or layer separation can not be caused easily. The surface of the carbonized wood layer has obvious wood grain, and the visual effect of the board can be improved.

Description

technical field [0001] The invention relates to the technical field of materials, in particular to an adsorption carbonized wood board and a preparation method thereof. Background technique [0002] The solid wood boards for furniture decoration in the current market are made of veneer, natural veneer, core board and other multi-layer solid wood materials laminated in a certain order, glued and pressed. High strength and other advantages. Existing solid wood boards are often treated with various organic solvents during the manufacturing process, and formaldehyde and other pollutants are likely to remain in the finished products. During use, the residual pollutants will volatilize and pollute the indoor environment. damage to human health. At the same time, paints, furniture and daily activities commonly used in interior decoration are also prone to produce a large amount of harmful pollutants, which permeate the indoor air for a long time, resulting in a decline in indoor ...
