NOVELTY - This new utility model relates to engineering anti-water material area, especially one of high intensity polyethylene waterproof coiled material, the self-cleaning from upper to lower is set with with titanium dioxide layer, rubber layer, the first polyethylene resin layer, graphene thin film layer, the second polyethylene resin layer, polypropylene fibre cloth layer. Titanium dioxide layer using anatase titanium dioxide porous thin film, the thickness is 50 to 180nm. The graphene thin film layer thickness is 5 to 80nm. This new utility model has high strength, high temperature resistance, corrosion resistance, using life long, bacteriostat effect and good character, and has a certain self-cleaning.
