▎ 摘　　要

NOVELTY - Flexible metal-based graphene electric heating material, comprises a flexible insulating layer, a flexible graphene resistance layer, a flexible insulating layer, and a metal substrate arranged sequentially from top to bottom. The flexible graphene resistor layer and flexible insulating layer are provided between rolled copper foil, where electric heating material bents inward with the metal substrate as the outermost layer until it is completely overlapped. USE - Flexible metal-based graphene electric heating material. ADVANTAGE - The electric heating material is a flexible material that can be bent, and has stable electrical properties. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing a flexible metal-based graphene electric heating material, which involves forming prepreg after the semi-cured glue is configured, stirring prepreg, dispersing and dipping prepreg by a dipping machine, drying and rolling, making a printing sheet by cutting the prepreg to obtain a printing sheet, adding the printing sheet to the graphene conductive paste for screen printing, drying and curing after completion to obtain screen printing sheet, stacking and laminating the printing sheet, the silk screen sheet, and the metal substrate, after trimming and drilling and milling to obtain an electric heating material. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a flexible metal-based graphene electric heating material.
