NOVELTY - Printable high-viscosity protective film comprises a hydrophobic coating (1), a polyethylene terephthalate film (2), a common viscose water (3) and a 25 µm transparent polyethylene terephthalate release bottom (4) from up to down. USE - Used as printable high-viscosity protective film. ADVANTAGE - The printable high-viscosity protective film has water-proof and moisture-proof, acid and alkali-resistant protection performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for method for preparing protective film comprising stirring and mixing the methyl polyurethane with the epoxy graphene in a ratio of 100:3.6 in purified water using a distillation flask, adding the inducer to analyze the pure ethyl ester, where the content of the ethyl ester is 2%, using the distillation condensing device to perform water bath constant temperature, heating at 70℃ to obtain the printable coating liquid with water resistance by evaporating ethyl ester, coating the upper surface of the polyethylene terephthalate film by using the roller coating technology, where the thickness of the coating is 2 μm, forming the hydrophobic coating, where the thickness of the polyethylene terephthalate film is 25 μm, using the comma coating head the viscose water under the polyethylene terephthalate film, where the thickness of the common viscose water is 24 μm, and extruding and adhering the lower part of the common glue with the bottom paper of the 25 μm transparent polyethylene terephthalate release bottom. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of printable high-viscosity protective film. 1Hydrophobic coating 2Polyethylene terephthalate film 3Common viscose water 4Transparent polyethylene terephthalate release bottom
