The prepared fluorocarbon film has excellent weather resistance, waterproof effect and mechanical strength, the F-C bond in the fluorocarbon film layer has strong energy, and ultraviolet light reaching a roof hardly has any influence on the fluorocarbon film layer, so that the ultraviolet light has low transmittance in the fluorocarbon film layer, and meanwhile, the transmittance of the fluorocarbon film layer to oxygen and water is small, so that the fluorocarbon film layer provides protection for a lower surface layer material, and the fluorocarbon film layer is also made of an inert material, so that the structure and the color of concentrated acid and concentrated alkali cannot be changed. Therefore, the fluorocarbon film layer 1 is arranged on the surface of the waterproof roll, so that the waterproof roll has good functions of better corrosion resistance, weather resistance, ultraviolet resistance and the like, and the waterproof roll is effectively prevented from aging and cracking. The waterproof layer 2 can improve the tensile property and the elongation of the waterproof roll. The modified butyl rubber layer 3 is prepared from modified butyl rubber components, so that the waterproof coiled material has the advantages of heat insulation, noise reduction, strong self-healing property, lasting strong bonding sealing property and the like. Particularly, the flexibility, the impermeability and the joint peeling strength at low temperature are greatly improved. The isolation layer 5 is structurally characterized in that a layer of silicone oil is coated on the surface of the PET film to reduce the adhesive force on the surface of the PET film, and further achieve the effect of isolation and water resistance. The fluorocarbon film composite waterproof coiled material has super-long durability, wide temperature resistance and aging resistance, is easy to construct and bond, can be constructed on a damp base surface at the temperature of minus 20 ℃, and has the service life of more than 40 years.
