NOVELTY - The utility model model claims a heating perforated gypsum board added graphene film, comprising a first metal layer, a first core layer, graphene film layer, a second core layer, a second metal layer; the opposite two sides of the graphene thin film layer provided with a mounting through hole, the mounting through hole is embedded with a conductive strip, between the first metal layer and the second metal layer is provided with a sound absorbing hole; the sound absorbing hole passes through the first core layer, graphene film layer and the second core layer; the sound-absorbing through hole is detachably embedded with a rigid insulating cylinder The utility model through the first metal layer and the second metal layer, improves the strength of the composite gypsum board, the utility model not only has the same use of the composite plasterboard of the existing technology, but also by setting graphene film layer to heat the plate body, to realize the warm function keeping of the device, can be used as the wall of the warm-keeping.
