Description

Technical Field

[0001] This utility model relates to the field of reconstituted bamboo technology, and in particular to a high weather-resistant reconstituted bamboo board. Background Technology

[0002] Early bamboo processing technology was limited, resulting in numerous defects in bamboo products, such as susceptibility to cracking and deformation, and insufficient strength. This restricted the wider application of bamboo. However, with continuous technological advancements, bamboo processing technology has achieved significant breakthroughs. For example, in 2009, the Institute of Wood Science of the Chinese Academy of Forestry developed a mechanical decomposition processing technology that eliminates the need to remove the green and yellow parts of bamboo. This technology increased the primary utilization rate of bamboo to over 90% and significantly improved production efficiency. The continuous improvement of forming technologies such as hot pressing and cold pressing, as well as processing techniques such as carbonization and impregnation, has greatly enhanced the performance of reconstituted bamboo boards, enabling them to meet the needs of various application fields. For instance, the hot pressing process can make small bamboo units denser and simultaneously allow the adhesive to fully cure, improving the strength and stability of the boards.

[0003] In daily use, the shortcomings of bamboo plywood in terms of its resistance to ultraviolet oxidation and corrosion will lead to a lack of durability in corrosive environments. Utility Model Content

[0004] The purpose of this invention is to provide a high-weather-resistant plastic heavy-duty bamboo board. By spraying epoxy resin onto the outer surface of the bamboo bundle layer to form an anti-corrosion layer, the epoxy resin itself has extremely strong chemical stability and can effectively resist corrosive substances such as acid rain and salt. When the board is in a humid outdoor environment, the continuous and dense structure of the anti-corrosion layer can prevent moisture from contacting the bamboo bundle layer, avoiding the bamboo from rotting and becoming moldy due to long-term dampness, and significantly improving the durability of the board in harsh climates and corrosive environments.

[0005] To achieve the above objectives, a high-weather-resistant plastic heavy-duty bamboo board is provided, comprising: a bamboo bundle layer; an anti-corrosion layer is provided on the outer surface of the bamboo bundle layer; the anti-corrosion layer is formed by spraying epoxy resin onto the outer surface of the bamboo bundle layer to form a continuous and dense protective coating; the anti-corrosion layer is formed by spraying epoxy resin onto the surface; and an anti-oxidation layer is provided on the upper surface of the bamboo bundle layer; the anti-oxidation layer is formed by spraying acrylic paint onto the upper surface of the bamboo bundle layer to form a continuous and dense protective coating. By constructing anti-corrosion and anti-oxidation layers with epoxy resin and acrylic paint respectively, the bamboo bundle layer is protected in all aspects, improving the weather resistance of the board.

[0006] According to the aforementioned high weather-resistant plastic heavy-duty bamboo board, the anti-corrosion layer has a U-shaped cross-section, and its upper surface is fixedly connected to the anti-oxidation layer. The U-shaped anti-corrosion layer and the anti-oxidation layer are fixedly connected to form a three-dimensional protective structure, enhancing the protective effect on the bamboo bundle layer.

[0007] According to the aforementioned high weather-resistant plastic heavy-duty bamboo board, the bamboo bundle layer is located inside the anti-corrosion layer, and the bamboo bundle layer is formed by hot pressing. The hot-pressed bamboo bundle layer is wrapped by the anti-corrosion layer, which not only ensures its own strength but also provides effective protection, extending its service life.

[0008] According to the aforementioned high weather-resistant plastic heavy-duty bamboo board, the two bamboo bundle layers are fixedly connected vertically, and a connecting layer is provided between the left and right sides of the two bamboo bundle layers. The fixed connection of the bamboo bundle layers vertically and horizontally, along with the provision of connecting layers, enhances the overall structural stability and integrity of the board.

[0009] According to the aforementioned high weather-resistant heavy-duty bamboo board, the connecting layer is made of bamboo fiber filler and adhesive, and there are two connecting layers, which are staggered. The staggered bamboo fiber filler and adhesive connecting layers optimize the mechanical properties of the board and improve its resistance to deformation.

[0010] The above-mentioned solution has the following beneficial effects:

[0011] This invention features an anti-corrosion layer and an anti-oxidation layer. The anti-corrosion layer is formed by spraying epoxy resin onto the outer surface of the bamboo bundle layer. Epoxy resin itself has extremely strong chemical stability and can effectively resist corrosive substances such as acid rain and salt. When the board is in a humid outdoor environment, the continuous and dense structure of the anti-corrosion layer can prevent moisture from contacting the bamboo bundle layer, thus avoiding the bamboo from rotting and becoming moldy due to long-term dampness. This significantly improves the durability of the board in harsh climates and corrosive environments.

[0020] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0021] Reference Figure 1-4 This invention discloses a high-weather-resistant plastic heavy-duty bamboo board, comprising: a bamboo bundle layer 1, with an anti-corrosion layer 3 on the outer surface of the bamboo bundle layer 1. The anti-corrosion layer 3 is formed by spraying epoxy resin onto the outer surface of the bamboo bundle layer 1 to form a continuous and dense protective coating. The anti-corrosion layer 3, through the dense structure formed by the epoxy resin, isolates external corrosive substances, effectively protecting the bamboo bundle layer 1 and extending the service life of the board. The anti-corrosion layer 3 is formed by spraying epoxy resin onto the surface. This spraying method ensures that the anti-corrosion layer 3 evenly covers the bamboo bundle layer 1, enhancing the protective effect and avoiding corrosion problems caused by weak local protection. An anti-oxidation layer 4 is provided on the upper surface of the bamboo bundle layer 1, formed by spraying acrylic paint onto the upper surface of the bamboo bundle layer 1 to form a continuous and dense protective coating. The anti-oxidation layer 4 utilizes the anti-oxidation properties of the acrylic paint to prevent the bamboo bundle layer 1 from oxidizing upon contact with oxygen, maintaining the stability of the board's performance.

[0022] The anti-corrosion layer 3 has a U-shaped cross-section, and its upper surface is fixedly connected to the anti-oxidation layer 4. The U-shaped anti-corrosion layer 3 and the anti-oxidation layer 4 are tightly connected, forming a comprehensive protective system that provides a double protective barrier for the bamboo bundle layer 1 from the sides and top. The bamboo bundle layer 1 is located inside the anti-corrosion layer 3 and is formed by hot pressing. The hot-pressed bamboo bundle layer 1 has good structural strength and is encased within the anti-corrosion layer 3, allowing it to utilize its own strength advantages while receiving effective protection. The two bamboo bundle layers 1 are fixedly connected vertically, and connecting layers 2 are provided between the left and right sides of each layer. These connecting layers 2 are made of bamboo fiber filler and adhesive. The connecting layers 2 utilize the high strength of the bamboo fiber filler and the adhesive properties of the adhesive to firmly connect the two bamboo bundle layers 1, enhancing the overall structural stability and integrity of the board. There are two connecting layers 2, which are staggered. The staggered connecting layers 2 further optimize the mechanical properties of the board, enabling it to withstand greater stress in all directions and improving its resistance to deformation.

[0023] Working principle: The bamboo bundle layer 1 is formed by hot pressing, giving it good structural strength and serving as the basic load-bearing structure of the board. Epoxy resin is sprayed onto the outer surface of the bamboo bundle layer 1 to form a continuous and dense U-shaped anti-corrosion layer 3, which isolates external corrosive substances and protects the bamboo bundle layer 1. Acrylic paint is sprayed onto the upper surface of the bamboo bundle layer 1 to form an anti-oxidation layer 4, preventing the bamboo bundle layer 1 from oxidizing upon contact with oxygen. Together with the anti-corrosion layer 3, this forms a protective system. A connecting layer 2 is made using bamboo fiber filler and adhesive to fix the two bamboo bundle layers 1 vertically. Two connecting layers 2 are also staggered between the left and right sides to enhance the overall structural stability and mechanical properties of the board. This completes the board assembly. The assembled high weather-resistant heavy-duty bamboo board, with its protective and structural advantages formed by the cooperation of its components, can be used in appropriate scenarios.

[0024] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
