NOVELTY - The utility model relates to the technical field of plate, and claims a graphene modified heat preservation and sound insulation plate, plate body, the plate body from inside to outside is provided with an insulating layer, a sound insulating layer, a sound absorbing layer and a noise reducing layer, the noise reducing layer outer side wall is uniformly provided with a plurality of sound absorbing component. The graphene modified heat preservation and sound insulation plate, reasonable design, simple structure, through the outer side of the plate body is provided with a sound absorbing layer, the sound absorbing layer is provided with a plurality of inner wall is sawtooth-shaped sound absorbing hole, matched with the sound absorbing ball in the sound absorbing hole, so that the sound wave transmission, can be more reflected on the inner wall of the saw tooth; and the energy of the sound wave when reflected gradually reduces the sound wave attenuation, so as to reduce the noise, and the graphene modified epoxy resin made of insulating layer can improve the heat preservation of the plate body, meet the requirement of people.
