Abstract
A self-cleaning coating and a film material for a decorative film and a preparation method thereof relate to the technical field of high polymer materials and comprise the following components in parts by mass: 90-110 parts of waterborne polyurethane, 50-100 parts of waterborne poly (perfluoroacrylate), 10-20 parts of perfluoropolyether methanol, 1-10 parts of monohydroxy silicone oil, 5-10 parts of cross-linking agent, 1-10 parts of conductive filler, 0.5-1 part of emulsifier and 50-150 parts of water. According to the self-cleaning paint for the decorative film, the perfluoro polyether methanol is adopted as a fluorinating agent, and side chain alkane is connected to the waterborne polyurethane, so that the oil-proof and water-proof performances of the waterborne polyurethane are endowed; and the monohydroxy silicone oil is added, the silicon section of the monohydroxy silicone oil forms bending filling in the pores of the membrane material to form a hydrophobic surface structure, and the surface tension is low, so that the aggregation of pollutants on the surface of the coating is further prevented, and the self-cleaning purpose is achieved.
Description
