Description

Technical Field

[0001] The invention relates to the technical field of decorative boards, and more particularly to a melamine veneer-pasted wooden decorative board composite structure. Background Art

[0002] Wood grain paper is a kind of special paper. Generally, wood pulp kraft paper is used as the base paper, and then the surface is processed by embossing, dyeing and other processes, and finally the wood grain paper with colorful patterns is produced. Wood grain paper is used in various fields because of its high ornamental value, strong practicality and high cost performance, especially for the packaging of various decorative products, mainly used for the surface decoration or trimming of furniture, speakers and other home office supplies.

[0003] Traditional melamine impregnated paper veneer 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 the particleboard, and hot pressing it to form a decorative board.

[0004] However, the existing decorative panels have poor strength and poor moisture resistance. Once water penetrates, it is easy for the entire panel to become damp and its strength to decrease. It is also easy for the decorative panels to expand due to moisture and shrink due to drying, causing cracks inside the decorative panels, thereby affecting the normal use of the decorative panels. Summary of the invention

[0005] In view of the problems existing in the prior art, the purpose of the present invention is to provide a composite structure of melamine veneer-pasted wooden decorative panels, which can ensure that water does not easily seep into the joints during use by arranging water-stop strips on the side walls around the base plate, and pre-embed transverse reinforcement tubes and vertical reinforcement tubes to form a mesh structure when the base plate is formed, which can greatly improve the structural strength of the decorative panels after forming. Even if water seeps into the surface of the decorative panels at a later stage, the transverse reinforcement tubes and vertical reinforcement tubes can easily sense it, and use the infiltrated moisture to trigger an early warning action, so that users can discover it in time and take corresponding treatment measures to avoid problems such as the decorative panels being affected by moisture for a long time and not being treated, resulting in a decrease in strength, which in turn affects the normal use of the decorative panels.

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

[0007] A melamine veneer-pasted wooden decorative board composite structure comprises a decorative board body, wherein the decorative board body comprises an upper melamine wood grain sticker, a lower melamine wood grain sticker and a substrate, wherein the upper melamine wood grain sticker and the lower melamine wood grain sticker are respectively laminated to the upper and lower surfaces of the substrate by hot pressing, and water stop strips are bonded to the side walls around the substrate, and a plurality of evenly distributed transverse reinforcement tubes and vertical reinforcement tubes are respectively inserted in two plane directions inside the transverse reinforcement tube, and the upper surfaces of the transverse reinforcement tubes and the vertical reinforcement tubes are fixedly connected with moisture-absorbing fiber strips.

[0008] Furthermore, the water-stop rubber strip includes a water-swellable rubber strip, a waterproof adhesive layer and a plurality of combining protrusions. The waterproof adhesive layer is arranged at one end of the water-swellable rubber strip close to the substrate. The combining protrusions are evenly distributed on the waterproof adhesive layer and correspond to the transverse reinforcement tube and the vertical reinforcement tube. 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 joints of the decorative panels, the water-swellable rubber strip will expand by absorbing water, thereby preventing further penetration of moisture. The function of the combining protrusions can help the water-swellable rubber strip to be better combined with the substrate, and at the same time can provide pre-buried reference points for the transverse reinforcement tube and the vertical reinforcement tube.

[0009] Furthermore, the horizontal reinforcement tubes and the vertical reinforcement tubes are staggered and distributed up and down to form a mesh structure. After forming the mesh structure, it can not only improve the self-strength of the substrate, but also provide more comprehensive coverage of the substrate. When the decorative panel becomes damp, the horizontal reinforcement tubes or the vertical reinforcement tubes can sense the moisture in time.

[0010] Furthermore, the base plate is made by mixing and pressing wood raw materials, which not only allows the reuse of scraps, but also facilitates the combination of water-stop strips, horizontal reinforcement tubes and vertical reinforcement tubes with the base plate.

[0011] Furthermore, the transverse reinforcement tube and the vertical reinforcement tube are both hollow tubular structures, and a plurality of evenly distributed isolation blocks are fixedly connected inside the transverse reinforcement tube and the vertical reinforcement tube, and a warning cavity is formed between adjacent isolation blocks. A plurality of overflow columns are fixedly connected inside the warning cavity, and the overflow columns extend to the outside to contact the hygroscopic fiber strips. The hygroscopic fiber strips can absorb the infiltrated moisture in time at the upper ends of the transverse reinforcement tube and the vertical reinforcement tube and then transport it to the vicinity of the overflow columns. The overflow columns release gas after contacting the moisture, which can prevent further penetration of moisture on the one hand and accelerate the evaporation of water vapor on the other hand. The isolation blocks can isolate the transverse reinforcement tube and the vertical reinforcement tube, so that they can play multiple roles and release gas in a more targeted manner.

[0012] Furthermore, the overflow column includes a water-soluble block and a gas storage cylinder connected up and down. The water-soluble block will trigger a gas release action after contacting water. The gas storage cylinder has a supporting effect on the water-soluble block and can store a certain amount of gas at the same time.

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

[0014] Furthermore, the warning cavity also stores a plurality of heating balls and scented powders. When the water-soluble block comes into contact with water and dissolves, on the one hand, carbon dioxide will be released, and on the other hand, the gas in the gas cylinder will overflow. The heating balls can react with the gas overflowing from the gas cylinder to generate heat, thereby releasing a large amount of heat, which can accelerate the dissipation of the fragrance of the scented powder, which can not only remind the user of moisture, but also cover up the musty smell caused by the moisture of the board.

[0015] Furthermore, the heating ball includes a hollow sphere, a waterproof breathable membrane and a self-heating inner core. The waterproof breathable membrane covers the outer surface of the hollow sphere, and the self-heating inner core is filled in the hollow sphere. The hollow sphere is provided with a plurality of evenly distributed air holes. The self-heating inner core can react with oxygen to release heat, and then the fragrance powder is heated through the hollow sphere to accelerate the emission of the fragrance. The waterproof breathable membrane can block the entry of moisture to 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 hard heat-conducting material.

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

[0018] (1) This solution can ensure that the joints are not prone to water seepage during use by setting water-stop strips on the side walls around the base plate, and pre-embed the transverse reinforcement tubes and vertical reinforcement tubes to form a mesh structure when the base plate is formed. The structural strength of the decorative board can be greatly improved after forming. Even if water seeps from the surface of the decorative board in the later stage, the transverse reinforcement tubes and vertical reinforcement tubes can easily sense it and use the infiltrated water to trigger an early warning action, so that users can discover it in time and take corresponding treatment measures to avoid problems such as the decorative board being damp for a long time without treatment, resulting in a decrease in strength, which in turn affects the normal use of the decorative board.

[0019] (2) In this solution, the water-swellable rubber strip is bonded to the side wall of the base plate through a waterproof adhesive layer, which can achieve good waterproof effect. When water seepage occurs at the joints of the decorative panels, the strip absorbs water and expands, thereby preventing further water penetration. Combined with the effect of the protrusions, the water-swellable rubber strip can be better combined with the base plate, and at the same time, a pre-buried reference point can be provided for the horizontal reinforcement tube and the vertical reinforcement tube.

[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 becomes damp, the horizontal reinforcement tube or the vertical reinforcement tube can sense the moisture in time.

[0021] (4) The hygroscopic fiber strips of the present invention can promptly absorb the infiltrated water at the upper ends of the transverse reinforcement tubes and the vertical reinforcement tubes and then transport them to the vicinity of the overflow column. The overflow column will release gas after coming into contact with the water. On the one hand, it can prevent the water from further penetrating, and on the other hand, it can accelerate the evaporation of water vapor. The isolation block can isolate the transverse reinforcement tube and the vertical reinforcement tube, so that they can play multiple roles and release gas in a more targeted manner.

[0022] (5) In this solution, when the water-soluble block comes into contact with water and dissolves, on the one hand, carbon dioxide will be released, and on the other hand, the gas in the gas cylinder will also overflow. The heating ball can react with the gas overflowing from the gas cylinder to generate heat, thereby releasing a large amount of heat, which can accelerate the dissipation of the fragrance of the fragrance powder. This can not only remind the user that the board is damp, but also cover up the musty smell caused by the dampness of the board.

[0023] (6) The self-heating inner core of the present invention can react with oxygen to release heat, and then heat the fragrance powder through the hollow sphere to accelerate the release of the fragrance. The waterproof and breathable membrane can block the entry of moisture to prevent interference with the heating reaction. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The first implementation method:

[0037] See also Figure 1-2A melamine veneer-pasted wooden decorative board composite structure comprises a decorative board body 1, the decorative board body 1 comprises 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 laminated to the upper and lower surfaces of the substrate 13 by hot pressing, the side walls of the substrate 13 are bonded with water stop strips 2, a plurality of evenly distributed transverse reinforcement tubes 3 and vertical reinforcement tubes 4 are respectively inserted in two plane directions inside the transverse reinforcement tube 3, and the upper surfaces of the transverse reinforcement tube 3 and the vertical reinforcement tube 4 are fixedly connected with moisture-absorbing fiber strips 5.

[0038] See also Figure 3 The water-stop rubber strip 2 includes a water-swellable rubber strip 21, a waterproof rubber layer 22 and a plurality of combining protrusions 23. The waterproof rubber layer 22 is arranged at one end of the water-swellable rubber strip 21 close to the substrate 13. The combining protrusions 23 are evenly distributed on the waterproof rubber layer 22 and correspond to the transverse reinforcement tube 3 and the vertical reinforcement tube 4. The water-swellable rubber strip 21 is bonded to the side wall of the substrate 13 through the waterproof rubber layer 22, which can achieve a good waterproof effect. When water seepage occurs at the joint of the decorative panel, it will expand by absorbing water, thereby preventing further penetration of moisture. The function of the combining protrusions 23 can help the water-swellable rubber strip 21 to be better combined with the substrate 13, and at the same time can provide a pre-buried reference point for the transverse reinforcement tube 3 and the vertical reinforcement tube 4.

[0039] See also Figure 4 The horizontal reinforcing tubes 3 and the vertical reinforcing tubes 4 are staggered and distributed up and down to form a mesh structure. After forming the mesh structure, it can not only improve the self-strength of the substrate 13, but also provide a more comprehensive coverage of the substrate 13. When the decorative panel becomes damp, the horizontal reinforcing tubes 3 or the vertical reinforcing tubes 4 can sense the moisture in time.

[0040] The base plate 13 is made by mixing and pressing wood raw materials, which not only allows the reuse of scraps, but also facilitates the combination of the waterproof strip 2, the horizontal reinforcement tube 3 and the vertical reinforcement tube 4 with the base plate 13.

[0041] See also Figure 5-6The transverse reinforcement tube 3 and the vertical reinforcement tube 4 are both hollow tubular structures. A plurality of evenly distributed isolation blocks 6 are fixedly connected inside the transverse reinforcement tube 3 and the vertical reinforcement tube 4. An early warning cavity is formed between adjacent isolation blocks 6. A plurality of overflow columns are fixedly connected inside the early warning cavity, and the overflow columns extend to the outside and contact with the hygroscopic fiber strips 5. The hygroscopic fiber strips 5 at the upper ends of the transverse reinforcement tube 3 and the vertical reinforcement tube 4 can absorb the infiltrated moisture in time and then transport it to the vicinity of the overflow columns. The overflow columns will release gas after contacting the moisture. On the one hand, it can prevent further penetration of moisture, and on the other hand, it can accelerate the evaporation of water vapor. The isolation blocks 6 can isolate the transverse reinforcement tube 3 and the vertical reinforcement tube 4, so that they can play multiple roles and release gas in a more targeted manner.

[0042] The overflow column includes a water-soluble block 7 and a gas storage cylinder 9 connected up and down. The water-soluble block 7 will trigger the gas release action after contacting with water. The gas storage cylinder 9 has a supporting effect on the water-soluble block 7 and can store a certain amount of gas at the same time.

[0043] The water-soluble block 7 is made of an effervescent disintegrant, and the gas cylinder 9 is a hollow structure made of a hard waterproof material, and air or oxygen is stored in the gas cylinder 9. The effervescent disintegrant is generally composed of sodium bicarbonate and citric acid, which will undergo a neutralization reaction when in contact with water, thereby generating a large amount of carbon dioxide.

[0044] A plurality of heating balls 8 and scented powders are also stored in the warning cavity. The scented powder may be a material with a scent that is easily volatile when heated, such as sandalwood. After the water-soluble block 7 comes into contact with water and dissolves, on the one hand, carbon dioxide will be released, and on the other hand, the gas in the gas cylinder 9 will also overflow. The heating ball 8 can react with the gas overflowing from the gas cylinder 9 to generate heat, thereby releasing a large amount of heat, which accelerates the dissipation of the scent of the scented powder, which can not only remind the user of moisture, but also cover up the musty smell caused by moisture in the board.

[0045] See also Figure 7 The heating ball 8 includes a hollow sphere 81, a waterproof breathable membrane 82 and a self-heating inner core 83. The waterproof breathable membrane 82 covers the outer surface of the hollow sphere 81, and the self-heating inner core 83 is filled in the hollow sphere 81. The hollow sphere 81 is provided with a plurality of evenly distributed air holes. The self-heating inner core 83 can react with oxygen to release heat, and then heat the fragrance powder through the hollow sphere 81 to accelerate the emission of the fragrance. The waterproof breathable membrane 82 can block the entry of moisture to prevent interference with the heating reaction.

[0046] The self-heating inner core 83 is made of a self-heating material, and the hollow sphere 81 is made of a hard heat-conducting material.

[0047] Working principle: When the decorative board body 1 becomes damp inside, the hygroscopic fiber strips 5 on the horizontal reinforcement tube 3 and the vertical reinforcement tube 4 can absorb moisture and transport it to the water-soluble block 7. The water-soluble block 7 dissolves and generates gas after coming into contact with moisture. After the water-soluble block 7 dissolves, the air or oxygen in the gas storage cylinder 9 is released, and 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 the fragrance faster, and cooperate with the gas to enter the outside along the moisture penetration channel, thereby having a good warning effect on the user and delaying the further penetration of moisture in the decorative board body 1.

[0048] The present invention can ensure that the connection is not prone to water seepage during use by arranging water-stop rubber strips 2 on the side walls around the base plate 13, and pre-buried transverse reinforcement tubes 3 and vertical reinforcement tubes 4 to form a mesh structure when the base plate 13 is formed, which can greatly improve the structural strength of the decorative board after forming. Even if water seepage occurs on the surface of the decorative board in the later stage, the transverse reinforcement tubes 3 and the vertical reinforcement tubes 4 can easily sense it, and use the infiltrated moisture to trigger an early warning action, so that the user can discover it in time and take corresponding treatment measures, so as to avoid the problem that the decorative board is not treated for a long time due to moisture and the strength decreases, which further affects the normal use of the decorative board.

[0049] The above are only preferred specific implementations of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and improved concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
