▎ 摘  要

NOVELTY - The utility model claims a graphene heating film with over-temperature protection, comprising a protective layer, a conductive layer and a graphene heating layer, wherein the graphene heating layer is graphene with PTC effect, conductive particles, high molecular material, solvent blend pressing or slurry casting or film layer formed by spraying on the base film; the thickness is between 0.01-2.00mm the conductive layer is connected with the external circuit, which is a thin layer consistent with the projection area of the heating layer, or is paved on two sides of the heating layer in strip shape; the outer layer is a protective layer. The utility model adopts graphene as heating raw material, and the PTC effect of the high molecular material graphene heating layer, under the condition of local overheating or short circuit, it can be self-protection, avoid the scald people or burning accident.
