Abstract

The invention provides a production method of a graphene heating film. The production method comprises the following steps: A, using a rapier loom to weave a graphene heating fabrc; B, using an ingredient mixing tank to prepare a macromolecule material; C, using a film forming device to fuse the macromolecule material so as to extrude a macromolecule material film; D, heat-sealing the macromolecule material film extruded in the step C to two sides of the heating fabric obtained in the step A in a double-faced synchronous heat-sealing manner; E, cooling an object obtained after lamination in the step D; and F, cutting deckle edges of an object obtained after cooling in the step E, and rolling to prepare the graphene heating film. The graphene heating film is simple in structure and convenient to use, a graphene heat conduction wire blending spinning silk yarn prepared fabric is used as a base material, and the macromolecule material layers are compounded on two sides of the fabric baselayer simultaneously to prepare the graphene heating film, so that the obtained graphene heating film is high in flexibility, low in manufacturing cost, free of stratification, light in weight and high in electrothermal efficiency.

Description

technical field [0001] The invention relates to the technical field of application of graphene materials, in particular to a graphene heating film and a production method thereof. Background technique [0002] The excellent performance of graphene completely exceeds that of metals, such as electrical properties: electron mobility at room temperature can reach 2×10 5 cm 2 / Vs, thermal conductivity: 5000 W / (mK), extraordinary specific surface area (2630 m 2 / g), Young's modulus (1100 GPa) and fracture strength (125 GPa); graphene's good mechanical properties and low density give it the potential to replace metals in the field of electrothermal materials. (Common metal resistance heating elements generally use metal foil, film coating, resistance wire, metal mesh and other materials. The most used heating element is nickel-chromium alloy. The density of nickel-chromium alloy is greater than 8 g / cm 3 When used, the thickness is several millimeters; the resistivity is low (...
