NOVELTY - The utility model claims a nano graphene extruded board, comprising a board body, a rigid layer, an insulating layer, a waterproof adhesive layer, substrate, fire-proof insulating layer, the expansion buffer layer, a framework, an elastic support rib, a foaming layer and a cement mortar levelling layer. The utility model is set with framework and an elastic support rib can deform the foaming layer, it can keep stable when the plate main body structure so as to prolong the service life of the plate main body, through fire-proof isolating layer can avoid fire outside the plate body, so as to improve the fireproof capability of the plate main body is provided with an insulating layer can increase the insulating effect of the plate main body, and the sheet body can adjust the indoor temperature, by setting the waterproof adhesive layer can prevent outer rain penetrates into the insulating layer through the rigid layer, it can avoid external factor causing damage the insulation layer by a rigid layer.
