[0019] In order to further illustrate the technical means and effects adopted by the present application to achieve the predetermined utility model purposes, the specific embodiments, structures, features and effects according to the present application are described in detail as follows in combination with the drawings and preferred embodiments.

[0020] The present application forms a plate structure by stacking and arranging graphene plates on the surface of a substrate, and enhances the plate by using the excellent performance of graphene. The graphene plates are located on the surface of the plate, and the excellent electrical conductivity, thermal conductivity, hydrophobicity, mildew resistance, corrosion resistance and deformation resistance of the graphene plates further improve the performance of the plate; the substrate composed of bamboo waste has good strength and stability.

[0021] The embodiments of the present application are further described in the following multiple embodiments.

[0022] The present application is prepared by the following steps:

[0023] First, 200-mesh graphene powder is prepared by crushing, screening and activating graphitized bamboo charcoal. Then, the same treatment process is performed on the bamboo plate waste to obtain bamboo plate waste powder. The bamboo plate waste powder is molded and cured at a temperature range of 800-1000℃ and a pressure of 0.5-1.0MPa to form a 3-5mm thick substrate and a 0.6-1mm thick base layer.

[0024] Secondly, mix the graphene powder and the adhesive according to a mass ratio of 3:1, evenly spread on the surface of the base layer (the thickness of the graphene layer is 0.01-0.3mm) to form a graphene plate, and then stack the graphene plate in a scale structure on the surface of the substrate. Under the temperature of 120-150℃ and the pressure of 0.8-1.2MPa, the curing process of the graphene layer and the substrate, the base layer is completed.

[0025] Finally, cool, edge cutting and sanding treatment are performed on the cured plate to obtain the finished product. In the sanding process, fine sandpaper and moderate pressure are used to remove burrs and unevenness on the surface and minimize the loss of the graphene layer. The specific parameters of the sanding process are as follows:

[0026] Preliminary sanding: use 180-220 mesh sandpaper to remove larger defects;

[0027] Fine sanding: use 320-400 mesh sandpaper to achieve a smoother surface;

[0028] Sanding speed: keep the sanding machine speed at 2000-3000 rpm per minute to ensure uniform sanding and reduce damage to the graphene layer;

[0029] Sanding frequency: according to the surface condition of the plate, it may need to be sanded 1-2 times preliminarily and 1 time finely.

[0030] By precisely controlling the sanding process parameters, the graphene powder coating layer is maximally preserved, ensuring that the functional properties of the plate such as thermal conductivity and hydrophobicity are not significantly affected.
