Abstract

The invention provides an anti-fouling TPU protection film for a car body. The anti-fouling TPU protection film comprises a TPU transparent film, a pressure-sensitive adhesive and an anti-sticking layer, wherein the surface of the TPU protection film contains an anti-fouling coating; the pressure-sensitive adhesive is an acrylate, polyurethane or organosilicon pressure-sensitive adhesive; and theanti-sticking layer is release paper or a PET release film. According to the invention, the aliphatic TPU film with low yellowing index is used as a basic film, and the surface tension of the film isimproved through solvent corrosion, so the adhesion of the anti-fouling coating on the surface of the film is improved; fluorocarbon-modified polyacrylate or organosilane-modified polyacrylate is usedas an anti-fouling component of the anti-fouling coating, so the coating has good self-cleaning performance, anti-fouling performance, transparency and compactness; and the film can be conveniently applied on the surface of the car body, can replace waxing, glaze sealing, paint spraying and the like of cars, and is also capable of improving the luster of the car body and protecting the car body from oil stains, water stains and scratches.
