Most composite woodworking boards have poor waterproof effects. Once water enters the interior of the composite woodworking board, it will cause the board to deform, mildew, and rot, seriously affecting its service life.

[0004] Particle board is a large-scale produced artificial wood board, which is bonded by adding resin and glue to wood chips, sawdust, and wood flakes. Particle board has the advantages of compact structure, high flatness, wear resistance, moisture resistance, and fire resistance. It is often used as raw material in the fields of furniture, floors, and building decoration materials. Therefore, it is considered to use science and technology veneer, solid wood veneer, and particle board to make a composite woodworking board to further improve the performance of the woodworking board.

The embodiments of the present utility model will be described below according to its overall structure.

[0030] As Figure 1 , 2 shown, this embodiment discloses a composite waterproof wood-based panel, which includes a solid wood board 1, a wood particle board 2, and a science and technology veneer 3. The upper and lower surfaces of the solid wood board 1 are respectively provided with the wood particle board 2, and the other side of the wood particle board 2 is provided with the science and technology veneer 3. The wood chips of the wood particle board 2 are smaller and the glue content is lower, which is more in line with the theme of modern green environmental protection home, and can also extend the service life of the solid wood board 1 inside the wood-based panel.

[0031] It is worth noting that the wood particle board 2 is hot-pressed from wood chips, adhesives, and paraffin. An appropriate amount of paraffin is added during the production of the wood particle board, and the content is generally controlled between 5% and 10%. It can increase the moisture-proof performance of the wood particle board, block the moisture on the outer surface of the wood particle board, so that the moisture can evaporate faster, and prevent the wood particle board from absorbing water and deforming and rotting.

[0032] Paraffin can react with the wood glue to form a "wax-wood glue complex", and can also enhance the toughness of the wood particle board, improve its seismic performance, and can also play the role of a lubricant, making the cutting process between the wood chips smoother, reducing tool wear, and effectively improving the quality and service life of the wood particle board.

[0033] The adhesive is a mixture of polyurethane adhesive, formaldehyde-free biomass adhesive, urea-formaldehyde glue, phenolic glue, melamine formaldehyde glue, waterproof agent, mildew-proof agent, and tackifier; the sizing amount of the adhesive is 7% - 35% of the weight of the wood chips. When using wood chips, the addition amount of the waterproof agent is 0.05% - 3.4% of the sizing amount, and the addition amount of the mildew-proof agent is 0.01% - 4.5% of the sizing amount; when using wood fibers, the addition amount of the waterproof agent is 0.3% - 0.6% of the sizing amount, and the addition amount of the mildew-proof agent is 0.1% - 0.4% of the sizing amount.

[0034] Generally, the solid wood board 1 can be set as a single-layer solid wood board or a multi-layer solid wood board, with a thickness of 18mm - 25mm; the wood particle board 2 is set as a multi-layer particle board, with a thickness of 9mm - 16mm; the thickness of the science and technology veneer 3 is 0.3mm - 0.6mm.

[0035] Continue to refer to Figure 3 In this embodiment, the wood particle board 2 is set as a multi-layer particle board with a thickness of 10 mm. The particles in its core layer 21 are thicker and coarser, and the particles on the surface layer 22 are thinner and finer. Compared with a single-layer particle board, the multi-layer particle board has higher strength, can significantly improve the hardness support of the surface veneer, is lighter and has better flexibility, is convenient to process and easy to operate, and also has good heat preservation, sound insulation, moisture-proof and other characteristics. Therefore, it is widely used in the decoration of living environments.

[0036] In order to improve the overall fire resistance of the composite waterproof wood board, the wood particle board 2 in this embodiment further includes a fireproof layer 23. The fireproof layer 23 is arranged on the side away from the solid wood board 1. The fireproof layer 23 is set as a wood fireproof coating layer, which is composed of a variety of high-efficiency flame retardant materials and high-strength film-forming substances, with a thickness of 0.8 mm to 1 mm. After encountering fire, it can quickly soften, expand and foam to form a dense honeycomb-like heat insulation layer, playing a role of fire resistance and heat insulation, and can meet the fire resistance requirements of decoration and furniture in living environments.

[0037] The veneer 3 in this embodiment uses ordinary wood as raw material, and through the principles of bionics and modern physical processing and chemical modification processes, such as veneer peeling, dyeing, lamination, hot pressing, etc., simulates the textures and colors of various precious woods, and can meet the personalized consumption needs of modern people.

[0038] The veneer 3 overcomes the original defects of natural wood. As the finishing material of the wood board, it can significantly improve the flatness of the outer surface. Moreover, the veneer 3 in this embodiment includes a wear-resistant layer 31. The wear-resistant layer 31 is arranged on the side away from the wood particle board 2. The wear-resistant layer 31 is set as an epoxy resin layer, with a thickness of 0.05 mm to 0.1 mm. Epoxy resin itself is non-toxic. The presence of inherent polar hydroxyl groups and ether bonds in the epoxy resin molecular chain makes it have a high adhesion to various substances, low shrinkage during curing, so there is no water or other volatile by-products released, and the internal stress generated is small. After curing, it has excellent wear resistance, alkali resistance, acid resistance and solvent resistance.

[0039] Thus, the functions achieved by a composite waterproof wood board in this embodiment are as follows:

[0040] (1) Waterproof and moisture-proof function

[0041] By setting that the wood particle board is made by hot pressing wood shavings, adhesives and paraffin wax, it can have better waterproof performance, block moisture on the outer surface of the wood particle board, so that the moisture can evaporate faster, prevent the wood particle board from absorbing water and deforming and rotting, thereby extending the service life of the solid wood board inside the wood board.

[0042] (2) Hardness support function

[0043] By setting the wood particle board as a multi-layer particle board, compared with a single-layer particle board, the multi-layer particle board has higher strength and can significantly improve the hardness support of the veneer on the outer surface.

[0044] (3) Fire prevention and flame retardant function

[0045] By providing a wood fireproof coating layer on the side of the wood particle board away from the solid wood board, it has the function of fire resistance and heat insulation, and can meet the fire prevention performance requirements of decoration and furniture in the living environment.

[0046] (4) Environmental protection and wear resistance function

[0047] By providing an epoxy resin wear-resistant layer on the side of the veneer away from the wood particle board, the epoxy resin itself is non-toxic, and after curing, it has excellent wear resistance, alkali resistance, acid resistance and solvent resistance.
