The utility model relates to the technical field of spraying anti-pollution protective adhesive tapes, in particular to a double-layer composite adhesive tape shielding film with an upper surface layer and a lower aluminum foil layer, which comprises an aluminum foil adhesive tape layer, a surface adhesive tape layer and a plastic film. The bottom of the aluminum foil tape layer is bonded with the plastic film, and the top of the aluminum foil tape layer is bonded with the bottom of the surface tape layer. The additionally arranged aluminum foil can effectively insulate heat and block the oxidation effect of ultraviolet rays on glue, so that the overall stability and waterproofness of the shielding film are improved; meanwhile, the phenomena that the whole shielding film falls off and leaks in the anti-pollution operation can be effectively solved; according to the color separation anti-pollution adhesive tape, the reasonable structural relation that the surface layer is arranged on the upper portion and the
