NOVELTY - The utility model claims an automobile paint surface protective film, especially a flame-retardant automobile paint surface protective film, comprising a composite sequentially double hydroxide/oxidized graphene nano composite film layer, a polyurethane coating, a TPU base film layer and a pressure-sensitive adhesive coating. The utility model solves the technical problem that the automobile paint surface protective film realizes flame-retardant by improving the layered structure. The utility model claims a flame-retardant automobile paint surface protective film, the structure of layered double hydroxide/oxidation graphene nanometer composite film layer has the synergistic flame-retardant effect, has high flame-retardant efficiency, so as to effectively prevent the smoke head or firecracker falling on the surface of the film caused by accident, It brings hidden trouble to life and property safety of people.
