NOVELTY - The utility model graphene a heating base material, comprising a graphene electric heating film and a connecting sheet, the connecting sheet are respectively located at two sides of the graphene electric heating film; a locating mechanism, the locating mechanism is located at the outer side of the connecting sheet; a connecting mechanism, the connecting mechanism is located at the outer side of the connecting sheet, the graphene of the two graphene electric heating films is corrected by the locating mechanism, and the two staggered connecting sheets are fixed to connect the two graphene electric heating films by the connecting mechanism, when the room is paved, if the sum of the width of the plurality of graphene electric heating film is different from the size of the room, the installation personnel by adjusting the overlapping length between the connecting sheet so that a plurality of graphene electric heating film can fill the whole room, because of the limiting of the locating mechanism, so that the mounting staff can avoid the graphene electro-thermal film two ends are inclined when adjusting the overlapping length, reducing the mounting difficulty of the mounting staff.
