PE protective film resistant to oil stain corrosion

The utility model discloses a PE (Poly Ethylene) protective film resistant to oil stain corrosion, which relates to the field of PE films and comprises a subbase layer, a sunscreen layer synthesized by nanoscale zinc oxide is coated on the upper surface of the subbase layer, an isolation layer for isolation is coated between the sunscreen layer and the subbase layer, and a non-stick layer synthesized by polytetrafluoroethylene is coated on the surface of the sunscreen layer. According to the PE protective film resistant to oil stain corrosion, the sunscreen layer, the non-stick layer and the sunscreen layer synthesized by nanoscale zinc oxide are arranged, the anti-oxidation function is achieved, meanwhile, zinc oxide is an N-type semiconductor, so that electrons on a valence band can receive energy in ultraviolet rays to generate transition, the ultraviolet rays can be absorbed, and the service life of the PE protective film is prolonged. The anti-oxidation effect of the subbase layer is directly improved fr
