Description

Technical Field

[0001] This invention relates to the field of decorative panel technology, and more specifically, to a melamine wood veneer wood decorative panel composite structure. Background Technology

[0002] Wood grain paper is a type of specialty paper. It typically uses virgin wood pulp kraft paper as the base paper, and then undergoes processes such as embossing and dyeing to produce wood grain paper with various colors and patterns. Due to its high aesthetic appeal, practicality, and cost-effectiveness, wood grain paper is used in various fields, especially in the packaging of decorative products, primarily for the exterior decoration or edge finishing of furniture, speakers, and other home and office supplies.

[0003] Traditional melamine-impregnated paper-faced particleboard is made by soaking paper with different colors or textures in melamine resin adhesive, then drying and curing it, laying it on the surface of particleboard, and then hot-pressing it to form a decorative board.

[0004] However, existing decorative panels have poor strength and poor moisture resistance. Once moisture seeps in, they are prone to becoming damp and losing strength. They are also prone to cracking due to expansion when damp and contraction when dry, which affects their normal use. Summary of the Invention

[0005] To address the problems existing in the prior art, the present invention aims to provide a melamine wood veneer wood decorative panel composite structure. This structure utilizes waterproof strips on the sidewalls of the substrate to prevent water seepage at joints during use. Furthermore, by pre-embedding horizontal and vertical reinforcing tubes during substrate molding to form a mesh structure, the structural strength of the decorative panel is significantly improved after molding. Even if water seepage occurs later, the horizontal and vertical reinforcing tubes can easily detect it and trigger an early warning system, allowing users to promptly identify and address the issue. This prevents the decorative panel from becoming damp and weakening over time, thus ensuring its normal use.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] A melamine wood veneer wood decorative panel composite structure includes a decorative panel body, which comprises an upper melamine wood grain sticker, a lower melamine wood grain sticker, and a substrate. The upper and lower melamine wood grain stickers are respectively hot-pressed onto the upper and lower surfaces of the substrate. Water-stop strips are adhered to the four sides of the substrate. Multiple evenly distributed horizontal and vertical reinforcing tubes are inserted into the interior of the horizontal reinforcing tubes in two planar directions. Moisture-absorbing fiber strips are fixedly connected to the upper surfaces of the horizontal and vertical reinforcing tubes.

[0008] Furthermore, the water-stop strip includes a water-swellable rubber strip, a waterproof adhesive layer, and multiple bonding protrusions. The waterproof adhesive layer is located at one end of the water-swellable rubber strip near the substrate. The bonding protrusions are evenly distributed on the waterproof adhesive layer and correspond to the horizontal and vertical reinforcing tubes. The water-swellable rubber strip is bonded to the side wall of the substrate through the waterproof adhesive layer, which can achieve a good waterproof effect. When water seepage occurs at the joint of the decorative panel, it absorbs water and expands, thereby preventing further water penetration. The bonding protrusions help the water-swellable rubber strip to bond better with the substrate and provide pre-embedded reference points for the horizontal and vertical reinforcing tubes.

[0009] Furthermore, the horizontal and vertical reinforcing tubes are arranged in a staggered mesh structure. This mesh structure not only improves the strength of the substrate itself but also provides comprehensive coverage. When the decorative panel becomes damp, the horizontal or vertical reinforcing tubes can detect the moisture in a timely manner.

[0010] Furthermore, the substrate is made by bonding wood raw materials with glue, which not only allows for the reuse of scraps, but also facilitates the bonding of water-stop strips, horizontal reinforcing tubes and vertical reinforcing tubes with the substrate.

[0011] Furthermore, both the horizontal and vertical reinforcing tubes are hollow tubular structures. Multiple evenly distributed isolation blocks are fixedly connected inside each tube, forming a warning cavity between adjacent isolation blocks. Multiple overflow columns are fixedly connected within each warning cavity, extending outwards to contact the moisture-absorbing fiber strips. The moisture-absorbing fiber strips can promptly absorb infiltrated moisture at the upper ends of the horizontal and vertical reinforcing tubes and then transport it to the vicinity of the overflow columns. Upon contact with moisture, the overflow columns release gas, which on one hand prevents further moisture penetration, and on the other hand accelerates water vapor evaporation. The isolation blocks can separate the horizontal and vertical reinforcing tubes, allowing them to perform multiple functions and release gas more specifically.

[0012] Furthermore, the overflow column includes a water-soluble block and a gas storage cylinder connected vertically. When the water-soluble block comes into contact with water, it will trigger a gas release action. The gas storage cylinder provides support for the water-soluble block and can store a certain amount of gas.

[0013] Furthermore, the water-soluble block is made of an effervescent disintegrant, and the gas storage cylinder is a hollow structure made of rigid waterproof material, and the gas storage cylinder stores air or oxygen. The effervescent disintegrant is generally composed of sodium bicarbonate and citric acid, which will undergo a neutralization reaction after contact with water, thereby producing a large amount of carbon dioxide.

[0014] Furthermore, the warning cavity also stores multiple heating balls and fragrance powder. When the water-soluble block comes into contact with water and dissolves, it will release carbon dioxide on the one hand, and the gas in the gas storage cylinder will also overflow on the other hand. The heating balls can react with the gas overflowing from the gas storage cylinder to release a large amount of heat, which will accelerate the dissipation of the fragrance powder. This can not only alert the user to the dampness, but also mask the musty smell caused by the dampness of the board.

[0015] Furthermore, the heating ball includes a hollow sphere, a waterproof and breathable membrane, and a self-heating inner core. The waterproof and breathable membrane covers the outer surface of the hollow sphere, and the self-heating inner core fills the interior of the hollow sphere. The hollow sphere has multiple evenly distributed vents. The self-heating inner core can react with oxygen to release heat, which is then used to heat the fragrance powder through the hollow sphere, accelerating the release of fragrance. The waterproof and breathable membrane can prevent moisture from entering and thus prevent interference with the heating reaction.

[0016] Furthermore, the self-heating inner core is made of a self-heating material, and the hollow sphere is made of a rigid thermally conductive material.

[0017] Compared with the prior art, the advantages of this invention are:

[0018] (1) This solution can ensure that the joints are not prone to water seepage when using by setting water-stop strips on the side walls around the substrate. The horizontal and vertical reinforcing tubes are pre-embedded during the substrate molding to form a mesh structure, which can greatly improve the structural strength of the decorative panel after molding. Even if water seepage occurs on the surface of the decorative panel later, the horizontal and vertical reinforcing tubes can easily detect it and trigger an early warning action by using the seeping water, so that users can discover and take corresponding measures in time, avoiding problems such as the decline in strength caused by long-term dampness of the decorative panel, which will affect the normal use of the decorative panel.

[0019] (2) The water-swellable rubber strip of this solution is bonded to the side wall of the substrate through the waterproof adhesive layer, which can achieve a good waterproof effect. When water seepage occurs at the joint of the decorative board, it will absorb water and expand, thereby preventing further water penetration. Combined with the protrusion, it can help the water-swellable rubber strip to better bond with the substrate. At the same time, it can provide pre-embedded reference points for the horizontal and vertical reinforcing tubes.

[0020] (3) After the mesh structure is formed, this solution can not only improve the strength of the substrate itself, but also provide a more comprehensive coverage of the substrate. When the decorative panel gets damp, the horizontal or vertical reinforcing tubes can detect the moisture in time.

[0021] (4) The moisture-absorbing fiber strips in this solution can absorb the permeated moisture at the upper end of the horizontal and vertical reinforcing tubes and then transport it to the vicinity of the overflow column. When the overflow column comes into contact with the moisture, it will release gas, which can prevent further water penetration on the one hand and accelerate the evaporation of water vapor on the other hand. The isolation block can isolate the horizontal and vertical reinforcing tubes, so that it can play multiple roles and release gas more specifically.

[0022] (5) After the water-soluble block comes into contact with water and dissolves, it will release carbon dioxide on the one hand, and the gas in the gas storage cylinder will also overflow on the other hand. The heating ball can react with the gas overflowing from the gas storage cylinder to release a large amount of heat, which will accelerate the dissipation of the fragrance powder. This can not only remind users of the dampness, but also mask the musty smell caused by the dampness of the board.

[0023] (6) The self-heating core of this solution can react with oxygen to release heat, and then heat the fragrance powder through the hollow sphere to accelerate the release of fragrance. The waterproof and breathable membrane can block moisture from entering and prevent interference with the heating reaction. Attached Figure Description

[0036] First implementation method:

[0037] Please see Figure 1-2A melamine wood veneer wood decorative panel composite structure includes a decorative panel body 1, which includes an upper melamine wood grain sticker 11, a lower melamine wood grain sticker 12, and a substrate 13. The upper melamine wood grain sticker 11 and the lower melamine wood grain sticker 12 are respectively hot-pressed onto the upper and lower surfaces of the substrate 13. Water-stop strips 2 are glued to the four sides of the substrate 13. Multiple evenly distributed horizontal reinforcing tubes 3 and vertical reinforcing tubes 4 are inserted into the two plane directions inside the horizontal reinforcing tubes 3. Moisture-absorbing fiber strips 5 are fixedly connected to the upper surfaces of the horizontal reinforcing tubes 3 and the vertical reinforcing tubes 4.

[0038] Please see Figure 3 The water-stop strip 2 includes a water-swellable rubber strip 21, a waterproof adhesive layer 22, and multiple bonding protrusions 23. The waterproof adhesive layer 22 is located at one end of the water-swellable rubber strip 21 near the substrate 13. The bonding protrusions 23 are evenly distributed on the waterproof adhesive layer 22 and correspond to the horizontal reinforcing tube 3 and the vertical reinforcing tube 4. The water-swellable rubber strip 21 is bonded to the side wall of the substrate 13 through the waterproof adhesive layer 22, which can achieve a good waterproof effect. When water seepage occurs at the joint of the decorative panel, it absorbs water and expands, thereby preventing further water penetration. The bonding protrusions 23 help the water-swellable rubber strip 21 to better bond with the substrate 13, and at the same time provide pre-embedded reference points for the horizontal reinforcing tube 3 and the vertical reinforcing tube 4.

[0039] Please see Figure 4 The horizontal reinforcing tubes 3 and vertical reinforcing tubes 4 are arranged in a staggered mesh structure. After forming the mesh structure, it can not only improve the strength of the substrate 13 itself, but also provide a more comprehensive coverage of the substrate 13. When the decorative panel gets damp, the horizontal reinforcing tubes 3 or vertical reinforcing tubes 4 can detect the moisture in time.

[0040] The substrate 13 is made by pressing wood raw materials together with glue, which not only allows for the reuse of scraps, but also facilitates the bonding of the water-stop strip 2, the horizontal reinforcing tube 3 and the vertical reinforcing tube 4 with the substrate 13.

[0041] Please see Figure 5-6Both the horizontal reinforcing tube 3 and the vertical reinforcing tube 4 are hollow tubular structures. Multiple evenly distributed isolation blocks 6 are fixedly connected inside the horizontal reinforcing tube 3 and the vertical reinforcing tube 4. An early warning cavity is formed between adjacent isolation blocks 6. Multiple overflow columns are fixedly connected inside the early warning cavity, and the overflow columns extend to the outside to contact the moisture-absorbing fiber strips 5. The moisture-absorbing fiber strips 5 can absorb the infiltrated moisture at the upper end of the horizontal reinforcing tube 3 and the vertical reinforcing tube 4 in a timely manner and then transport it to the vicinity of the overflow columns. When the overflow columns come into contact with moisture, they will release gas, which can prevent further moisture infiltration on the one hand, and accelerate the evaporation of water vapor on the other hand. The isolation blocks 6 can isolate the horizontal reinforcing tube 3 and the vertical reinforcing tube 4, so that they can play multiple roles and release gas more specifically.

[0042] The overflow column includes a water-soluble block 7 and a gas storage cylinder 9 connected vertically. When the water-soluble block 7 comes into contact with water, it will trigger a gas release action. The gas storage cylinder 9 provides support for the water-soluble block 7 and can store a certain amount of gas.

[0043] The water-soluble block 7 is made of effervescent disintegrant. The gas storage cylinder 9 is a hollow structure made of rigid waterproof material and contains air or oxygen. The effervescent disintegrant is generally composed of sodium bicarbonate and citric acid. When it comes into contact with water, it will undergo a neutralization reaction and produce a large amount of carbon dioxide.

[0044] The warning cavity also stores multiple heating balls 8 and fragrance powder. The fragrance powder can be materials such as sandalwood that easily release fragrance when heated. After the water-soluble block 7 comes into contact with water and dissolves, it will release carbon dioxide on the one hand, and the gas in the gas storage cylinder 9 will also overflow. The heating balls 8 can react with the gas overflowing from the gas storage cylinder 9 to release a large amount of heat, which will accelerate the dissipation of the fragrance powder. This can not only alert users to moisture, but also mask the musty smell caused by moisture in the board.

[0045] Please see Figure 7 The heating ball 8 includes a hollow sphere 81, a waterproof and breathable membrane 82, and a self-heating inner core 83. The waterproof and breathable membrane 82 covers the outer surface of the hollow sphere 81, and the self-heating inner core 83 fills the interior of the hollow sphere 81. The hollow sphere 81 has multiple evenly distributed vents. The self-heating inner core 83 can react with oxygen to release heat, which is then used to heat the fragrance powder through the hollow sphere 81, accelerating the release of fragrance. The waterproof and breathable membrane 82 can prevent moisture from entering and prevent interference with the heating reaction.

[0046] The self-heating core 83 is made of self-heating material, and the hollow sphere 81 is made of rigid thermally conductive material.

[0047] Working principle: When the decorative panel body 1 becomes damp inside, the moisture-absorbing fiber strips 5 on the horizontal reinforcing tube 3 and the vertical reinforcing tube 4 can absorb moisture and transport it to the water-soluble block 7. After the water-soluble block 7 comes into contact with moisture, it dissolves and generates gas. After the water-soluble block 7 dissolves, the air or oxygen in the gas storage cylinder 9 is released. The self-heating core 83 in the heating ball 8 can react with oxygen to generate a large amount of heat, thereby prompting the fragrance powder to release fragrance more quickly. Combined with the gas, it enters the outside through the moisture penetration channel, thus providing a good warning effect to the user and delaying the further penetration of moisture into the decorative panel body 1.

[0048] This invention ensures that the joints are not prone to water seepage during use by setting water-stop strips 2 on the side walls of the substrate 13. The horizontal reinforcing tubes 3 and vertical reinforcing tubes 4 are pre-embedded during the molding of the substrate 13 to form a mesh structure, which can greatly improve the structural strength of the decorative panel after molding. Even if water seepage occurs on the surface of the decorative panel later, the horizontal reinforcing tubes 3 and vertical reinforcing tubes 4 can easily detect it and trigger an early warning action by using the seeping water, so that users can discover and take corresponding measures in time, avoiding problems such as the decline in strength caused by long-term dampness of the decorative panel, which would affect the normal use of the decorative panel.

[0049] The above are merely preferred embodiments of the present invention; however, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concept, should be covered within the scope of protection of the present invention.
