NOVELTY - The utility model relates to the technical field of graphene, claims a double-layer graphene heating film, in order to improve the efficient use of the graphene heating film for heating, the lower part of the heating core layer is connected with a first graphene heating film, and the upper part of the heating core layer is connected with a second graphene heating film; the lower part of the first PET film is connected with a moisture-proof layer; the lower part of the moisture-proof layer is connected with an insulating paving bottom layer; the upper part of the second PET film is connected with an anti-impact layer. The utility model is matched and combined by double graphene heating film, not only can provide enough heating to the room, at the same time, it can isolate the cold air from the underground, the indoor and outdoor heating is kept in the range of balance, and in the using process; by the passive elastic restoring force of the insulating layer and the moisture-proof layer; under the elastic impact resistance of the anti-impact layer, it can improve the anti-impact ability of the graphene heating film.
