NOVELTY - The utility model claims a heating film taking graphene as heating body, comprising a graphite heat-conducting layer, the upper surface of the graphite heat-conducting layer and the lower surface are respectively and fixedly provided with a protective layer and an insulating layer, the bottom of the insulating layer is provided with an electrode layer, the bottom end of the electrode layer is provided on the surface with an insulating layer, a protective layer is fixed is provided with a waterproof layer, the upper surface of the waterproof layer is provided with a buffer layer, the top end of the buffer layer is provided with an abrasion-resistant layer, the material of the heat insulating layer is heat insulating silica gel, the buffer layer is provided with a cavity; and inside of the hollow cavity is provided with a plurality of heat conducting sheet. This utility model set a heat insulating layer can be well to insulate heat, so that the heat can be better used, simultaneously the prepared heat insulating layer made of heat insulating silica gel, it has better effect of buffering and damping, it can better protect the heating film, improve the practicability of the heating film.
