Patent number: 11701871Abstract: The present utility model provides an easy-to-clean protective film, which belongs to the technical field of protective films for vehicles and other vehicles, and can solve the problems that lasting scratches are easily caused to the existing vehicle coatings and surface stains are not easy to clean. The easy-to-clean protective film provided by the present utility model comprises a polyvinyl chloride (PVC) bottom film and an easy-to-clean layer consisting of silicon dioxide particles, wherein the water contact angle of the easy-to-clean layer is small and thus the adhesive force of dust and oil stains can be reduced. After the surface of the easy-to-clean layer is contaminated by dust and oil stains, the dust and oil stains can be easily cleaned with a simple cleaning. The easy-to-clean protective film provided by the present utility model is suitable for use as protective coatings of various substrates, especially for attachment to the body surfaces of vehicles such as automobiles.Type: GrantFiled: January 10, 2019Date of Patent: July 18, 2023Assignee: 3M INNOVATIVE PROPERTIES COMPANYInventors: Pei Huang, Xue-hua Chen
