Description

Technical Field

[0001] This utility model relates to the field of panel decoration technology, and more specifically, to an environmentally friendly moisture-proof painted door panel. Background Technology

[0002] In the modern construction industry, as people's demands for the quality of their living and working environments continue to rise, higher requirements are being placed on the performance of building materials. Sound insulation performance, as one of the important indicators for measuring the quality of building materials, directly affects people's living comfort and work efficiency. At the same time, environmental protection, moisture resistance, and rust prevention are also receiving increasing attention.

[0003] Traditional soundproofing panels have several shortcomings in practical applications. First, some soundproofing materials may contain harmful substances, releasing pollutants such as formaldehyde during use, which can harm human health and contradict current environmental protection principles. Second, many panels have poor moisture resistance, easily warping in humid environments, reducing sound insulation effectiveness and even shortening the panel's lifespan. Third, some panels lack effective rust prevention measures for their frames; prolonged use can lead to rust, affecting aesthetics and potentially causing structural instability.

[0004] Furthermore, traditional sound insulation panels have shortcomings in the way their functional layers are bonded. For example, the connections between layers are not tight enough, making delamination easy and reducing the overall performance of the panel. Moreover, some existing sound insulation panels often focus only on improving a single performance aspect, neglecting the synergistic optimization of other performance aspects, making it difficult to meet the comprehensive performance requirements of modern buildings. Utility Model Content

[0005] Based on the above-mentioned technical problems, this utility model proposes an environmentally friendly moisture-proof painted door panel.

[0006] An environmentally friendly, moisture-proof painted door panel, comprising:

[0007] A wood-based substrate board, with an inner cavity in the middle, the inner cavity being filled with an environmentally friendly sound-insulating board;

[0008] The outer layer is fixedly connected to the left and right sides of the substrate board by water-based adhesive, and the outer surface of the outer layer is covered with a moisture-proof carbon fiber layer.

[0009] The substrate board has a frame at each of its four edges, and the outer surface of the frame is covered with a continuous carbon fiber covering layer integrally formed with the carbon fiber layer of the outer layer board.

[0010] Preferably, the environmentally friendly sound insulation board is a recycled polyester fiber board or plant fiber sound-absorbing board that has been treated with anti-mildew agents, and its thickness accounts for 50%-70% of the total thickness of the substrate board.

[0011] Preferably, the moisture-proof carbon fiber layer is a carbon fiber prepreg with a surface coated with a nano-silica hydrophobic coating, and the thickness is 0.3-1.2 mm.

[0012] Preferably, the frame is made of anodized aluminum alloy profile or PVC profile with added anti-mildew agent, and its inner side is connected to the substrate board by a tenon and mortise structure.

[0013] Preferably, the surface of the wood substrate is coated with a graphene-containing moisture-proof coating, the thickness of which is 0.05-0.2 mm.

[0014] Preferably, the outer layer is a formaldehyde-free bamboo fiberboard, and a basalt fiber reinforced mesh is provided between it and the carbon fiber layer.

[0015] Preferably, the joints between the substrate, the inner cavity, and the frame are filled with silicone moisture-proof sealant.

[0016] Beneficial effects:

[0017] 1. Excellent environmental performance: The board uses recycled polyester fiber board or plant fiber sound-absorbing board that has been treated with anti-mildew as an environmentally friendly sound insulation board, bamboo and wood fiber board without added formaldehyde as an outer board, and water-based adhesives for connection. This ensures the environmental friendliness of the board from multiple aspects and reduces the harm to human health and the environment.

[0018] 2. Excellent sound insulation effect: The environmentally friendly sound insulation board is filled in the inner cavity. Its reasonable thickness design and its own good sound insulation and sound absorption performance can effectively block and absorb sound, significantly improve the sound insulation effect of the board, and create a quiet and comfortable space environment for users.

[0019] 3. Excellent moisture-proof performance: The surface of the moisture-proof carbon fiber layer is coated with a nano-silica hydrophobic coating, combined with the graphene-containing moisture-proof coating on the surface of the wood substrate board, and the silicone moisture-proof sealant filled at the joints, forming a comprehensive moisture-proof protection system that effectively prevents moisture from penetrating the board, avoids the board from being damaged by moisture and deformation, and extends the service life of the board.

[0020] 4. High structural stability: The materials of each layer are tightly connected by reasonable connection methods, such as setting basalt fiber reinforced mesh between the outer layer and the carbon fiber layer, and using mortise and tenon structure to connect the frame and the base plate, which effectively prevents the delamination between the layers and ensures the stability of the board structure, so that it can maintain good performance during long-term use.

[0025] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0026] like Figures 1-3 The environmentally friendly moisture-proof painted door panel shown is mainly composed of a wood substrate board 1, an environmentally friendly sound insulation board 3, an outer layer board 4, a carbon fiber layer 5, and a frame 6.

[0027] Wood-based substrate board and environmentally friendly sound insulation board: Wood-based substrate board 1 serves as the basic supporting structure of the entire board. It has an inner cavity 2 in the middle, which is filled with an environmentally friendly sound insulation board 3. The environmentally friendly sound insulation board 3 is a recycled polyester fiber board or plant fiber sound-absorbing board that has been treated with anti-mildew. Both of these materials have good sound insulation performance and are made of recycled materials or plant fibers, which is in line with the concept of environmental protection. Its thickness accounts for 50% to 70% of the total thickness of substrate board 1. This thickness design can maximize the sound insulation effect while ensuring the overall strength of the board. The environmentally friendly sound insulation board filled in the inner cavity can not only effectively block the transmission of sound, but also absorb some noise by utilizing its own material properties, further improving the sound insulation performance.

[0028] Outer Layer and Moisture-Resistant Carbon Fiber Layer: The outer layer 4 is fixedly connected to the left and right sides of the base material 1 using a water-based adhesive. Compared to traditional adhesives, water-based adhesives are environmentally friendly and pollution-free, conforming to the environmentally friendly design concept of this invention. The outer layer 4 is made of formaldehyde-free bamboo fiberboard or magnesium cement board. Both materials inherently possess certain strength and stability, and the absence of formaldehyde further ensures the environmental friendliness of the board. The outer surface of the outer layer 4 is covered with a moisture-resistant carbon fiber layer 5. The carbon fiber layer 5 is a carbon fiber prepreg with a surface coated with a nano-silica hydrophobic coating, and its thickness is 0.3 mm. -1.2mm; The nano-silica hydrophobic coating has excellent hydrophobic properties, which can effectively block the intrusion of external moisture and protect the board from moisture. The carbon fiber prepreg itself has high strength. After being combined with the outer layer, it not only enhances the moisture resistance of the board, but also improves the overall strength and durability of the board. In addition, a basalt fiber reinforced mesh is provided between the outer layer 4 and the carbon fiber layer 5. The basalt fiber reinforced mesh can enhance the bonding force between the outer layer and the carbon fiber layer, prevent the two from delaminating, and improve the stability of the board structure.

[0029] Frame: The four edges of the base material board 1 are provided with frame 6. The frame 6 is made of anodized aluminum alloy profile or PVC profile with added mildew inhibitor. The anodized aluminum alloy profile has good rust resistance and high strength, while the PVC profile with added mildew inhibitor not only prevents rust but also prevents mold growth, further improving the durability and hygiene of the board. The inner side of the frame 6 is connected to the base material board 1 by a tenon and mortise structure. The tenon and mortise structure has the characteristics of tight connection and high stability, which can ensure a firm connection between the frame and the base material board and enhance the overall structural strength of the board. The outer surface of the frame 6 is covered with a continuous carbon fiber covering layer integrally formed with the carbon fiber layer 5 of the outer layer board 4. This integral design not only makes the appearance of the board more beautiful, but also further enhances the moisture-proof and rust-proof performance of the board edges, while improving the overall structural stability of the board.

[0030] Moisture-proof coating: The surface of the wood substrate board 1 is coated with a graphene-containing moisture-proof coating with a thickness of 0.05-0.2mm. Graphene has excellent barrier properties and can effectively block the penetration of moisture, further enhancing the moisture-proof performance of the wood substrate board. The moisture-proof coating protects the wood substrate board from the inside and forms a double moisture-proof protection with the outer moisture-proof carbon fiber layer, ensuring that the board can maintain good performance in humid environments.

[0031] Sealant filling: The joint between the substrate board 1, the inner cavity 2 and the frame 6 is filled with silicone moisture-proof sealant. The silicone moisture-proof sealant has good sealing and moisture-proof performance, which can effectively prevent moisture from seeping into the interior of the board from the joint, protect the internal structure of the board from moisture, and further improve the moisture-proof performance and structural stability of the board.

[0032] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
