[0026] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments:

[0027] Example 1:

[0028] See Figure 1 , Figures 5-7A corrosion-resistant and heat-insulating board includes a board body 1, on which a corrosion-resistant and heat-insulating layer is coated. The corrosion-resistant and heat-insulating layer includes a graphene layer 2, a composite microsphere layer 3, and a barium sulfate layer 4 arranged sequentially.

[0029] In this embodiment, from bottom to top, the components are: the main body of the plate 1, the graphene layer 2, the composite microsphere layer 3, and the barium sulfate layer 4.

[0030] Among them, the graphene layer 2, the composite microsphere layer 3 and the barium sulfate layer 4 can all be applied to the corresponding layers by spraying or brushing, or arranged in a composite manner.

[0031] The two-layer structure of graphene in graphene layer 2 can form a dense network barrier, effectively blocking the penetration of water, oxygen and corrosive particles, delaying substrate corrosion. At the same time, its high conductivity can promote electron transfer. When combined with the metal substrate, it may act as a sacrificial anode or form a passivation layer to inhibit electrochemical corrosion. The high infrared reflectivity of graphene can reflect some thermal radiation and reduce heat absorption.

[0032] In this embodiment, the composite microsphere layer 3 can be an expanded microsphere or a hollow glass microsphere, that is, a composite microsphere layer is composed of multiple expanded microspheres or multiple hollow glass microspheres. The multiple expanded microspheres or multiple hollow glass microspheres can be formed into a layered component by adhesive.

[0033] Microsphere-filled coatings can reduce porosity and extend the diffusion path of corrosive media. Expanded microspheres and hollow glass microspheres can also reduce the water absorption rate of the coating. At the same time, microspheres help to reduce the thermal conductivity of the coating.

[0034] The barium sulfate layer is resistant to acid and alkali corrosion, improving the stability of the coating in harsh environments. High-density particles fill the pores of the coating, enhancing its compactness and reducing the penetration of corrosive media. At the same time, it improves the hardness and wear resistance of the coating, preventing mechanical damage. The high refractive index can reflect some heat radiation, and the irregular particle arrangement scatters heat, reducing heat conduction efficiency. Increasing the coating thickness can indirectly improve heat insulation.

[0035] In one embodiment, an adhesive layer is disposed between the graphene layer 2 and the composite microsphere layer 3, and between the composite microsphere layer 3 and the barium sulfate layer 4, so as to arrange them in a composite manner. Of course, an adhesive layer can also be disposed between the anti-corrosion and heat insulation layer composed of the graphene layer 2, the composite microsphere layer 3 and the barium sulfate layer 4 and the surface of the main body of the board.

[0036] In one embodiment, a plurality of internal grooves 11 are stamped on the sheet body 1 to divide the sheet body 1 into several blocks 12, which helps to improve the overall strength of the sheet body 1 and enhance its aesthetics. Figure 5 As shown.

[0037] In one embodiment, the side of the main body 1 of the plate is bent to form a folded edge 13, while the inner groove 11 does not have a corresponding folded edge 13 to reduce the processing difficulty. Several mounting holes are provided on the folded edge 13 and / or on the main body 1 of the plate to facilitate the installation of the plate.

[0038] In one embodiment, the guard strip 9 used for assembling the panels has at least two snap-fit ​​grooves 91 arranged at right angles, so that after the two panel bodies 1 are installed on the guard strip 9, the two panel bodies 1 are arranged perpendicular to each other, serving as two adjacent walls of an outdoor room such as a tool shed. Figure 6 As shown.

[0039] Correspondingly, at least one side of the main body 1 of the plate includes a snap-fit ​​strip 14 for engaging with the snap-fit ​​groove 91 on the guard strip 9. In use, the snap-fit ​​strip 14 is inserted from one end of the snap-fit ​​groove 91 until the entire snap-fit ​​strip 14 is inserted into the snap-fit ​​groove 91. The snap-fit ​​strip 14 and the snap-fit ​​groove 91 can be in the form of...
