Abstract

The invention discloses a fluoridized TPU car body film. The fluoridized TPU car body film sequentially comprises a PET peeling layer, an adhesive layer, a TPU base material and a hydrophobic anti-fouling coating from bottom to top, wherein the hydrophobic anti-fouling coating comprises, in parts by mass, 25-35 parts of polyphenylene sulfide, 30-45 parts of a fluorinated ethylene propylene emulsion, 2-6 parts of aluminum oxide, 1-3 parts of sodium sulfite and 20-30 parts of deionized water. The fluoridized TPU car body film has atmosphere aging resistance, can resist harsh weather such as acid rain, wind, snow and the like and has high anti-radiation performance and lower permeability, and the surface and performance can keep unchanged even if the car body film is exposed in the atmosphere for a long time; the car body film is non-sticky and has a self-cleaning property and a smooth and transparent surface, so that dirt cannot stick to the car body film easily, the car washing frequency can be reduced, and the car body film is energy-saving and environment-friendly; the car body film has repairability and is scratch-resistant, small scratches on the surface can automatically disappear, and the appearance of a car is under no influence, the car body film is non-toxic and pollution-free and meets the specification standard for national-level environment-friendly additives and the like.

Description

technical field [0001] The invention relates to the field of polymer films, in particular to a TPU fluorine-coated body film, a preparation method and application thereof. Background technique [0002] As the air pollution becomes more and more serious, the moisture, oil, dust and other substances in the atmosphere will cause serious pollution to the surface of the car body. Therefore, developing a polymer film with corrosion resistance, self-cleaning, self-repairing, atmospheric aging resistance, non-toxic and non-polluting properties is an urgent problem in the automotive industry. At present, the car body film on the market can only achieve the above-mentioned single or individual performances in the actual application process, and the use effect is average, which cannot meet the increasingly higher requirements for car body protection. Contents of the invention [0003] The purpose of the present invention is to provide a thermoplastic polyurethane elastomer rubber (T...
