Description

Technical Field

[0001] This utility model relates to the field of decorative artificial board technology, specifically a decorative artificial board with high wear resistance and crack resistance. Background Technology

[0002] With the booming development of the interior decoration industry, decorative engineered wood panels have become a commonly used material in furniture manufacturing and interior decoration due to their combination of aesthetics and practicality.

[0003] Based on the above, the inventors have discovered the following problems: Ecological boards in decorative engineered wood panels are composed of multiple layers of materials, including a substrate, a facing paper, and adhesives. Different materials have different coefficients of thermal expansion. When the ambient temperature changes frequently, internal stress is generated in each layer due to the different degrees of thermal expansion and contraction. The substrate is mostly wood fiberboard, which has a relatively large coefficient of thermal expansion, while the facing paper and adhesives have smaller coefficients. When the temperature rises, the substrate expands, but is constrained by the facing paper and adhesives, causing internal stress to gradually accumulate. When the temperature drops, the substrate contracts, which in turn stretches the facing paper. This repeated stress ultimately leads to cracks appearing on the surface of the ecological board.

[0004] Therefore, in view of this, we will study and improve the existing structure and its shortcomings to provide a decorative artificial board with high wear resistance and crack resistance, in order to achieve a more practical value. Utility Model Content

[0005] The purpose of this utility model is to provide a highly wear-resistant and crack-resistant decorative artificial board to solve the problem mentioned in the background art that the existing decorative artificial boards are composed of multiple layers of composite materials with different coefficients of thermal expansion. When the ambient temperature changes frequently, the different degrees of thermal expansion and contraction of each layer of material will generate internal stress, which will lead to cracking of the board.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0007] A highly wear-resistant and crack-resistant decorative engineered wood panel includes a panel body and an edging. The edging is disposed on the outer side of the panel body, and the inner side of the edging is connected to the outer wall of the panel body via hot melt adhesive. The panel body includes a base layer, a first reinforcing layer, a first wear-resistant layer, a first decorative coating, a second reinforcing layer, a second wear-resistant layer, and a second decorative coating. The upper surface of the base layer is bonded with the first reinforcing layer using epoxy resin adhesive. The upper surface of the first reinforcing layer is bonded with the first wear-resistant layer using melamine-formaldehyde resin adhesive. The upper surface of the first wear-resistant layer is provided with the first decorative coating. The bottom end of the base layer is bonded with the second reinforcing layer using epoxy resin adhesive. The bottom end of the second reinforcing layer is bonded with the second wear-resistant layer using melamine-formaldehyde resin adhesive. The bottom end of the second wear-resistant layer is provided with the second decorative coating. Further, the base layer is a plywood, and the first and second reinforcing layers are both fiberglass mesh.

[0008] The beneficial effects of adopting the above-mentioned further solutions are that the base layer is made of plywood, which has a stable structure and high strength, providing a solid foundation for the board; the first and second reinforcing layers are made of fiberglass mesh, which has the characteristics of high strength and high toughness, effectively enhancing the board's resistance to deformation and overall strength, preventing the board from cracking, and improving the board's durability.

[0009] Furthermore, the upper surface of the first reinforcing layer is coated with a first unsaturated polyester resin, and the bottom surface of the second reinforcing layer is coated with a second unsaturated polyester resin.

[0010] The beneficial effects of adopting the above-mentioned further solution are that the first unsaturated polyester resin on the upper end of the first reinforcing layer and the second unsaturated polyester resin on the bottom end of the second reinforcing layer can enhance the bonding force between the reinforcing layer and the adjacent layers, so that each layer is tightly bonded and the stability of the board structure is improved. At the same time, the unsaturated polyester resin has high hardness after curing, and when combined with glass fiber mesh, it can better enhance the deformation resistance and overall strength of the base layer.

[0011] Furthermore, both the first and second wear-resistant layers are made of impregnated paper.

[0012] The beneficial effects of adopting the above-mentioned further solution are that the first wear-resistant layer and the second wear-resistant layer are made of impregnated paper. Impregnated paper has good wear resistance, scratch resistance and corrosion resistance, which can effectively resist friction and scratches in daily use, extend the service life of the board, and at the same time, its rich surface texture can enhance the decorativeness of the board.

[0013] Furthermore, both the first and second finishing coatings are polyurethane transparent varnishes, and the thickness of the first and second finishing coatings is 0.1 to 0.2 mm.

[0014] The beneficial effects of adopting the above-mentioned further solution are that the first and second decorative coatings are made of polyurethane transparent varnish, and the thickness is controlled at 0.1 to 0.2 mm. Polyurethane transparent varnish has good wear resistance, chemical resistance and gloss. The two work together to further improve the wear resistance of the decorative artificial board, while giving the board a bright appearance. The thickness of 0.1 to 0.2 mm can ensure the protective and decorative effect of the coating without affecting the overall performance and texture of the board.

[0015] Furthermore, the edging is made of ABS material.

[0016] The beneficial effects of adopting the above-mentioned further solution are that the edge banding is made of ABS material. ABS material has the advantages of high hardness, good toughness, impact resistance and chemical corrosion resistance, which can effectively protect the edge of the artificial board and prevent the edge from being damaged by collision and friction. At the same time, it has strong weather resistance, is not easy to age or discolor, and can maintain a good appearance for a long time, thereby improving the service life and overall quality of the board.

[0017] Compared with existing technologies, the beneficial effects of this utility model are as follows: This highly wear-resistant and crack-resistant decorative artificial board has edges connected to the board body via hot melt adhesive, which protects the edges of the board and prevents edge wear and moisture. The base layer of the board body provides basic support, the first and second reinforcing layers enhance the overall strength of the board, the first and second wear-resistant layers improve the wear resistance of the board, and the first and second decorative coatings give the board a good decorative effect. The multi-layer structure works synergistically to give the board high wear resistance, crack resistance, and aesthetics. The base layer is made of plywood, which has a stable structure and high strength, providing a solid foundation for the board. Providing a solid foundation; the first and second reinforcing layers are made of fiberglass mesh, which has high strength and high toughness, effectively enhancing the board's resistance to deformation and overall strength, preventing cracking, and improving durability. The first unsaturated polyester resin on the upper surface of the first reinforcing layer and the second unsaturated polyester resin on the bottom surface of the second reinforcing layer enhance the adhesion between the reinforcing layers and adjacent layers, ensuring a tight bond between each layer and improving the stability of the board structure. At the same time, the high hardness of the unsaturated polyester resin after curing, combined with the fiberglass mesh, can better enhance the base layer's resistance to deformation and overall strength.
