NOVELTY - The utility model claims a toughened protection film, comprising orderly laminated toughened glass layer, the radiation-proof coat, graphene layer and adhesive layer, the radiation-proof coat is coated on the bottom surface of the toughened glass layer, the graphene layer is coated on the radiation-proof coating, wherein the thickness of said toughened glass layer is 600 to 1200 microns, the thickness of the radiation-proof coat is 15 to 30 microns, the thickness of the graphene layer is 0.335 to 100nm. This utility model of steel protective film improves the radiating effect through the graphene layer, and the high strength and toughness combined with toughened film enhances the function of the protective screen, small whole thickness, thin, durable, and good comprehensive performance.
