▎ 摘　　要

NOVELTY - Graphene heating film includes a first waterproof layer, a graphene layer, an electrode strip, a thermal insulation layer and a second waterproof layer arranged in layers, and the sides of the first waterproof layer and the second waterproof layer are bonded to each other. A wire hole is opened on the side of the first waterproof layer or the second waterproof layer, and the electrode strip is connected with the wire through the wire hole. An anti-aging layer is arranged on the second waterproof layer, and a decorative layer is arranged on the anti-aging layer. USE - Graphene heating film for industrial and civil construction as a bottom snow and ice removal device (claimed). ADVANTAGE - The graphene heating film has waterproof, fast heating and heating equalization, has simple operation, and improves the appearance beauty of the heating film, and the safety of the worker and citizen. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation method of the graphene heating film, which involves pasting the graphene film on the surface of the substrate to form a graphene layer, pasting the first waterproof layer on the surface of one side of the graphene layer, pasting the electrode strip on the other surface of the graphene layer, and pasting the second waterproof layer on the side of the electrode strip away from the graphene layer, opening lead hole on the side of the first waterproof layer pasted with the second waterproof test, connecting the external lead to the electrode strip through the lead hole, and connecting the side of the first waterproof layer and the second waterproof layer to form a sealing structure, pasting an anti-aging layer on the upper surface of the second waterproof layer, and pasting decorative layer on the upper surface of the anti-aging layer to prepare a graphene heating film.
