NOVELTY - The utility model claims a graphene insulating protective film layer, comprising a graphene layer, the top of the graphene layer fixedly connected with with a protective layer, the material of the protective layer is a parrelin coating, the top part of the protective layer is provided with a flame-retardant layer, the top of the flame-retardant layer fixedly connected with surface layer; the material of the flame-retardant layer is polyurethane material; the flame-retardant layer and the protective layer are adhered to each other by silica gel. The utility model is coated with a protective layer on the surface of the graphene layer, which can meet the nano-micron level protection requirement, and the flame retardant layer can avoid the graphene layer after long time use after spontaneous combustion, by setting the surface layer, can protect the structure of the bottom of the surface layer to avoid the flame retardant layer; the protective layer or graphene layer is subjected to collision and abrasion; it solves the problem that the existing graphene protective material structure and function are single; it cannot satisfy the use requirement of graphene protective material in various environments; it reduces the problem of graphene protective material application range.
