[0019] The following will clearly and completely describe the technical solution of this application in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of this application.
[0020] The present application discloses a stain-resistant poplar multilayer board. Figure 1 and Figure 2 The stain-resistant poplar multilayer board includes two adhesive boards 10, two stain-resistant sheaths 20, a board core 30, and four protective plates 40. When the stain-resistant poplar multilayer board is processed, the two stain-resistant sheaths 20 can be respectively covered and set on the two adhesive boards 10 and bonded and fixed. Then, the two adhesive boards 10 coated with the stain-resistant sheaths 20 can be respectively inserted into the upper and lower inner parts of the board core 30 and bonded and fixed to the board core 30. Finally, a protective plate 40 can be set on each of the opposite sides of the adhesive board 10 in the longitudinal direction, and the protective plates 40 can be inserted into the board core 30 and bonded and fixed thereto. After completing the above processing, the board core 30 and the four protective plates 40 can surround the outer edges of the two adhesive boards 10 coated with the stain-resistant sheaths 20, so that the main use surface of the board can use the stain-resistant sheaths 20 to improve the stain resistance of the board. In addition, the seams of the stain-resistant sheaths 20 themselves can be hidden inside the board core 30. In addition, the entire outer edge of the board can be protected from water, acid and alkali, and corrosion by using the board core 30 and the protective plate 40.
[0021] See Figure 3 The core 30 includes a middle section 31 that separates the two adhesive sheets 10. Side sections 32 are formed on opposite sides of the middle section 31 in the width direction. Extension sections 33 are formed at the top and bottom of the side sections 32 and extend perpendicularly to the side sections 32. A slot 34 is formed between the middle section 31, the side sections 32, and the extension sections 33, allowing the adhesive sheets 10 to be positioned and inserted into adjacent slots 34 during processing.
[0022] In this embodiment, the shape and size of the guard plate 40 are respectively adapted to the shape and size of the notch on the end face of the board core 30, and after the guard plate 40 is bonded and fixed to the board core 30, the outer side surface of the guard plate 40 can be made flush with the outer wall of the adjacent end face of the board core 30.
[0023] In this embodiment, both the core 30 and the protective plate 40 can be made of wood-plastic materials to create the desired structure. Wood-plastic materials can be made primarily from natural wood fibers from agricultural waste, such as sawdust, bamboo shavings, rice husks, wheat straw, soybean hulls, peanut shells, and sugarcane bagasse, along with chemical raw materials such as plastic fillers and modifiers. After processing, they are rheologically molded into a reversible, recyclable, high-quality wood substitute. Wood-plastic materials have excellent physical and mechanical properties, high bearing capacity, resistance to deformation, and a long service life. They are also water-resistant, insect-resistant, fungus-resistant, acid- and alkali-resistant, and corrosion-resistant.
[0024] See Figure 4 The adhesive plate 10 includes a plurality of substrates 11 and a panel 12. During processing, the plurality of substrates 11 are stacked and placed, and two adjacent substrates 11 are bonded and fixed. In addition, the panel 12 is bonded and fixed to a substrate 11 near the extension section 33 among the plurality of substrates 11. The panel 12 is formed with positioning grooves 121 on both opposite sides along its width direction, which match the core 30, so that when the adhesive plate 10 as a whole is inserted into the slot 34, the concave and convex parts of the two can be spliced together. The side of the adhesive plate 10 coated with the anti-fouling sheath 20 near the extension section 33 is flush with the outer wall of the extension section 33, and the side of the adhesive plate 10 coated with the anti-fouling sheath 20 facing the side section 32, the extension section 33 or the protective plate 40 is bonded and fixed to the side section 32, the extension section 33 or the protective plate 40.
[0025] In this embodiment, the panel 12 can be made from a single solid wood board to preserve its natural grain, resulting in a more aesthetically pleasing finish. For example, a single solid wood board made from poplar wood has a clear, natural grain and high aesthetic value, making poplar wood furniture more visually appealing and significantly enhancing the decorative effect of a home. Furthermore, poplar wood has a soft, warm color that blends well into various interior environments, making our living spaces more comfortable and pleasant.
[0026] In this embodiment, the multiple substrates 11 are configured as a solid wood board, either as a single piece or by splicing or pressing together. This allows for better utilization of the wood raw material and reduces costs. For example, a spliced solid wood board can be formed by joining small, processed pieces of solid wood together with jagged joints, like "fingers." A pressed solid wood board can be formed by pressing together wood chips with glue and additives.
[0027] In this embodiment, the stain-resistant cover 20 can be made from a transparent PVC or PU cushion. During processing, the PVC or PU cushion is placed around the outer circumference of the adhesive sheet 10 and the two ends of the PVC or PU cushion are bonded together to form the stain-resistant cover 20. The PU cushion is made from a polyurethane resin and filler, while the PVC cushion is made from polyvinyl chloride, a plasticizer, and filler. Both PVC and PU cushions are relatively soft, have good stain and wear resistance, and are easy to wipe clean.
[0028] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
