Abstract
Description
Technical Field
[0001] The utility model relates to a plate, in particular to an outdoor graphitized bamboo board waste carbon-based plate. Background Art
[0002] As people's awareness of environmental protection and health increases, the demand for outdoor building materials is also increasing. Traditional outdoor panels have shortcomings in wear resistance, corrosion resistance, and environmental friendliness. Bamboo waste, as a renewable resource, has the advantages of widespread availability and low cost. However, its poor mechanical properties and weather resistance limit its application. Summary of the Invention
[0003] To overcome these shortcomings, the present invention provides an outdoor carbon-based board made from graphitized bamboo waste. Honeycomb-shaped through-holes enhance the board's mechanical properties, effectively dispersing and transmitting external pressure. The board also absorbs energy through deformation of the cell walls, enhancing its overall mechanical resistance. Furthermore, the high strength and low weight of the honeycomb through-holes save material and reduce costs. Furthermore, the graphite carbon layer adheres to the surface of the substrate and the walls of the honeycomb through-holes, providing excellent thermal conductivity, hydrophobicity, mildew and corrosion resistance, and deformation resistance. The substrate provides excellent strength and stability.
[0004] A carbon-based plate material made of graphitized bamboo board waste for outdoor use comprises a substrate having honeycomb-shaped through holes arranged transversely in a direction parallel to the plate surface, and two sides of the honeycomb through holes are parallel to the upper and lower surfaces of the substrate; a graphite carbon layer is adhered to the surface of the substrate and the pore walls of the honeycomb through holes.
[0005] The graphite powder of the graphite carbon layer is prepared by a molten salt electrochemical method; the substrate is prepared by crushing, screening, activating, and hydrothermal carbonizing bamboo board waste; a phenolic resin adhesive is used, and the adhesive and the graphite powder are mixed with each other and then adhered.
[0006] The method for preparing outdoor graphitized bamboo board waste carbon-based board materials of the present application includes screening, crushing, activation, mixing, gluing, honeycomb through-hole molding, cooling, trimming and sanding.
[0007] Furthermore, the lateral spacing between adjacent honeycomb through holes is 0.5-2 mm.
[0008] Furthermore, the longitudinal spacing between adjacent honeycomb through holes is 0.5-2 mm.
[0009] Furthermore, the substrate has three rows of multiple honeycomb through holes arranged transversely in a direction parallel to the plate surface.
[0010] Furthermore, the diameter of the honeycomb through-holes is 3 to 20 mm. The honeycomb is a regular hexagon, and its diameter is the diameter of the circumscribed circle of the regular hexagon.
[0011] The beneficial effects of this application are:
[0012] The honeycomb-shaped through-holes not only enhance the sheet's mechanical properties, enabling it to effectively disperse and transmit external pressure, but also absorb energy through deformation of the cell walls, enhancing overall mechanical resistance. Furthermore, the high strength and low weight of the honeycomb through-holes save material and reduce costs. Furthermore, the graphite carbon layer adhered to the substrate surface and the honeycomb through-hole walls provides excellent thermal conductivity, hydrophobicity, mildew and corrosion resistance, and deformation resistance; the substrate provides excellent strength and stability.

[0017] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments.
[0018] This application improves the mechanical properties and hydrophobicity of the plate by setting up honeycomb through holes. The graphite carbon layer adheres to the surface of the substrate and the hole walls of the honeycomb through holes, further enhancing the hydrophobicity of the plate. At the same time, it also has good thermal conductivity, mildew and corrosion resistance, and deformation resistance.
[0019] The following is a further description of the embodiments of the present invention with reference to a plurality of embodiments.
[0020] This application is prepared by the following steps:
[0021] First, graphitized bamboo charcoal is crushed, screened, and activated to prepare 200-mesh graphite powder. Bamboo board waste is crushed, screened, activated, and other treatments to prepare bamboo board waste. The board waste is then solidified by molding at a certain temperature (800-1000°C) and pressure (0.5-1.0MPa) to form a substrate with honeycomb through-holes. The size and distribution of the honeycomb through-holes are determined by the mold.
[0022] Then, the graphite powder and adhesive are mixed evenly in a certain proportion (graphite powder: adhesive = 3:1 (mass ratio)), coated on the surface of the substrate and the pore walls of the honeycomb through-holes, and cured at a certain temperature (120-150°C) and pressure (0.8-1.2MPa).
[0023] Finally, the cured board is cooled, trimmed and sanded to obtain the final product.
[0024] While sanding does polish the plywood surface to remove burrs and unevenness, the use of fine sandpaper and moderate pressure ensures a smooth finish without excessive loss of the surface graphite layer. Precisely controlling sanding process parameters maximizes the retention of the graphite powder coating, ensuring the board's thermal conductivity, hydrophobicity, and other functional properties are not significantly affected.
