Description

Technical Field

[0001] This utility model mainly relates to the technical field of engineered wood panels, specifically a waterproof engineered wood panel for household use. Background Technology

[0002] Engineered wood products (AWD) are a general term for boards made from wood, sawdust, or other plant fibers. They are lightweight and resistant to deformation. AWD is favored for its excellent performance and wide range of applications. It is mainly used in furniture manufacturing, interior decoration, and the construction industry. As people's requirements for home environments continue to increase, the demands for environmental friendliness, aesthetics, and durability in engineered wood products are also rising. Therefore, when purchasing engineered wood products, it is necessary to pay attention to their environmental protection rating, quality standards, and manufacturing processes.

[0003] According to application number CN201420606195.X, a type of engineered wood panel includes an integrally thermoformed first substrate layer and a second substrate layer. A reinforcing layer is disposed between the first substrate layer and the second substrate layer. The materials of the first substrate layer and the second substrate layer are wood fibers or plant fibers mixed with 4%-6% by weight of chopped carbon fibers. The reinforcing layer is made of conductive carbon fiber fabric. This invention proposes an engineered wood panel in which a reinforcing layer made of conductive carbon fiber fabric is nested and composited within the engineered wood panel. This allows for the pre-laying of conductive carbon fiber fabric between two layers of board blanks during the manufacturing process, followed by thermoforming the two layers of board blanks and the conductive carbon fiber fabric together.

[0004] In existing technologies, engineered wood products are made from wood fibers or other plant fibers, which inherently possess a certain degree of water absorption. Therefore, when engineered wood products are exposed to humid environments for extended periods, they easily absorb moisture, leading to swelling, deformation, and even mold growth. If engineered wood products are soaked in water for a prolonged period or subjected to strong water currents, their waterproof performance will be severely challenged. In such cases, the boards are prone to significant swelling, deformation, and even disintegration. Therefore, the problem of durable waterproofing in engineered wood products urgently needs to be solved. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a waterproof household engineered wood panel to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A waterproof household engineered wood panel includes a first waterproof layer, a first reinforcing fiber layer, a core board layer, a second reinforcing fiber layer, and a second waterproof layer, which are stacked sequentially.

[0008] The first waterproof layer is impregnated with and cured onto the surface of the first reinforcing fiber layer by waterproof resin, forming a continuous waterproof barrier; the second waterproof layer has the same material and structure as the first waterproof layer.

[0009] The first and second reinforcing fiber layers are tightly bonded to both sides of the core plate layer with high-strength adhesives.

[0010] A microporous breathable membrane is provided between the core plate layer and the first reinforcing fiber layer and the second reinforcing fiber layer, and between the first waterproof layer and the first reinforcing fiber layer, and between the second waterproof layer and the second reinforcing fiber layer.

[0011] Preferably, both the first reinforcing fiber layer and the second reinforcing fiber layer are three-dimensional interwoven glass fiber mesh or carbon fiber mesh.

[0012] Preferably, the waterproof resin is a modified polyurethane resin or epoxy resin, which has excellent water resistance and weather resistance, and the waterproof layer formed after curing has a uniform thickness of not less than 1.5 mm.

[0013] Preferably, the pore size of the microporous breathable membrane is controlled between 0.1 and 1 μm.

[0014] Preferably, a waterproof edge sealing strip is also provided at the edge of the board, and the waterproof edge sealing strip is made of the same waterproof material as the first waterproof layer.

[0015] Preferably, the core plate layer has raised structures distributed in a rectangular array at the top and bottom.

[0016] Preferably, the first reinforcing fiber layer and the second reinforcing fiber layer are provided with grooves on the side near the core plate layer, and the grooves are provided in correspondence with the protrusions.

[0017] In summary, this technical solution has the following main advantages:

[0018] This invention uses a method of impregnating and curing with waterproof resin to form a continuous waterproof layer, rather than a simple waterproof adhesive layer; a microporous breathable membrane is introduced to balance waterproof and breathable performance; a three-dimensional interwoven reinforcing fiber layer is used to improve the overall strength of the board; and a waterproof edge sealing strip is set at the edge of the board to further enhance the edge waterproofing capability.

Detailed Implementation

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Example

[0024] like Figures 1 to 2 As shown, a waterproof household engineered wood panel includes a first waterproof layer 10, a first reinforcing fiber layer 20, a core board layer 30, a second reinforcing fiber layer 40, and a second waterproof layer 50, which are stacked sequentially.

[0025] The first waterproof layer 10 is impregnated with waterproof resin and cured on the surface of the first reinforcing fiber layer 20 to form a continuous waterproof barrier; the second waterproof layer 50 has the same material and structure as the first waterproof layer 10.

[0026] The first reinforcing fiber layer 20 and the second reinforcing fiber layer 40 are tightly bonded to both sides of the core plate layer 30 with high-strength adhesives to enhance the overall structural strength.

[0027] A microporous breathable membrane 60 is provided between the core board layer 30 and the first reinforcing fiber layer 20 and the second reinforcing fiber layer 40, and between the first waterproof layer 10 and the first reinforcing fiber layer 20, and between the second waterproof layer 50 and the second reinforcing fiber layer 40. This facilitates the expulsion of moisture from the board interior without compromising the waterproofing effect.

[0028] Both the first reinforcing fiber layer 20 and the second reinforcing fiber layer 40 are three-dimensional interwoven glass fiber mesh or carbon fiber mesh to increase the tensile strength and impact resistance of the sheet.

[0029] The waterproof resin is a modified polyurethane resin or epoxy resin, which has excellent water resistance and weather resistance, and the waterproof layer formed after curing is of uniform thickness, not less than 1.5mm.

[0030] The pore size of the microporous breathable membrane 60 is controlled between 0.1-1μm. It can effectively prevent moisture penetration while ensuring gas exchange inside the board, thus preventing mold growth.

[0031] A waterproof edge sealing strip 70 is also provided at the edge of the board, and the waterproof edge sealing strip 70 is made of the same waterproof material as the first waterproof layer 10. It is fixed by hot melting or mechanical pressing to further improve the waterproof performance of the board edge.

[0032] The core plate layer 30 has raised structures 31 arranged in a rectangular array at the top and bottom.

[0033] The first reinforcing fiber layer 20 and the second reinforcing fiber layer 40 are provided with grooves 21 on the side near the core plate layer 30, and the grooves 21 are correspondingly provided with the protrusions 31.

[0034] It should be noted that in this embodiment, a continuous waterproof barrier is formed by impregnating and curing the surfaces of the second waterproof layer 50 and the first waterproof layer 10 with waterproof resin. This arrangement ensures effective waterproof protection for both the inner and outer sides of the board. It improves the water resistance of the board, enabling it to resist moisture erosion in daily life and extending its service life. Simultaneously, the continuous waterproof barrier prevents moisture from penetrating into the interior of the board, thus avoiding problems such as expansion and deformation caused by moisture.

[0035] The first reinforcing fiber layer 20 and the second reinforcing fiber layer 40 are made of three-dimensional interwoven glass fiber mesh or carbon fiber mesh, and are tightly bonded to the core board layer 30 with a high-strength adhesive. This significantly enhances the overall structural strength of the board, giving it higher tensile strength and impact resistance. This structure makes the board less prone to cracking or deformation when subjected to external forces, improving its safety in use.

[0036] As the main body of the panel, the core panel layer 30 provides necessary support and stability. It ensures the overall thickness and strength of the panel, enabling it to meet the needs of different application scenarios. At the same time, the material and structural design of the core panel layer 30 also affect the panel's sound insulation, heat insulation, and other performance characteristics.

[0037] The microporous breathable membrane 60 is installed inside the board, with its pore size controlled between 0.1-1μm. This effectively prevents moisture penetration while ensuring gas exchange within the board. This design avoids mold growth caused by moisture accumulation inside the board and also helps maintain its dryness and cleanliness.

[0038] The first reinforcing fiber layer 20 and the second reinforcing fiber layer 40 are embedded with grooves 21 on the side near the core board layer 30. Corresponding to the raised structures 31 distributed in a rectangular array on the top and bottom of the core board layer 30, the structural rigidity of the artificial board is further increased. During long-term use, the artificial board is not easily deformed, further ensuring the waterproof effect.

[0039] The above embodiments are only for illustrating the technical concept of this utility model and should not be construed as limiting the scope of protection of this utility model. Any modifications made to the technical solution based on the technical concept proposed by this utility model shall fall within the scope of protection of this utility model.
