The invention relates to a silvering reflective film. The reflective film structurally comprises a high-refractive-index resin layer, a barrier layer, a basic film layer, a silver reflective film layer, a corrosion resistant glue layer and a reinforced reflecting layer arranged successively. The basic film layer serves as the reflection side, and the high-refractive-index resin layer and the barrier layer are added to the reflection side to further improve the reflectivity and corrosion resistance of the reflective film. The reinforced reflecting layer is combined with the surface of the silver reflective film layer, a corrosion inhibitor easy to be complex with silver is added to binding agent to form the corrosion resistant glue layer, the silver surface is protected against corrosion ofwater, oxygen, halide and sulfur contained gas, the service life of the silvering reflective film is prolonged, and the integral performance of the silvering reflective film is improved substantially. The silvering reflective film is excellent in weatherability, long in service life, high in reflectivity and high in damage resistance, and has a strong adhesive force of the silver layer.
