Abstract

The invention relates to the technical field of graphene electric heating films, and discloses a graphene electric heating film and a preparation method thereof. The graphene electric heating film comprises a graphene electric heating film body formed by sequentially and compositely connecting an insulating heat conduction layer, a graphene electric heating film layer, an insulating heat insulation layer and a film forming substrate, wherein a plurality of hollowed-out holes are formed in a graphene electric heating film layer in the graphene electric heating film body, and the plurality of hollowed-out holes are uniformly arranged. According to the invention, the plurality of hollowed-out holes are formed in the graphene electric heating film layer, and the plurality of hollowed-out holes can be processed on a specific mold for producing the graphene electric heating film layer, so the use amount of preparation materials can be reduced to a certain extent, production and preparation cost is saved, the lightweight use requirement is met, and an actual use range is widened.

Description

technical field [0001] The invention relates to the technical field of graphene electric heating film, in particular to a graphene electric heating film and a preparation method thereof. Background technique [0002] The heating principle of the electric heating film is that under the action of an electric field, the huge friction and impact between molecules generate heat energy that is transmitted outward in the form of far-infrared radiation and convection. As a new heating method, the electric heating film brings great benefits to the heating field A new round of revolution is coming; compared with traditional heating, electric heating membrane has the functions of pollution-free, low-carbon environmental protection, self-regulation, meeting individual needs, safe and reliable, no water overflow, regulating physiological balance and promoting metabolism. [0003] The existing graphene electric heating film layer is mostly formed into a rectangle or a circle, which can me...
