The invention discloses a self-cleaning plastic rain boot with a super-amphiphobic coating. The surface of the plastic rain boot is sprayed with a super-amphiphobic coating. The preparation method comprises the following steps: S1, using PVC resin, carbon black, diethylene glycol and a plasticizer , toughening agent and anti-aging agent to prepare rain boots blank; S2, prepare hydrophobic water-based polyurethane emulsion and modified titanium dioxide nanoparticles, and then mix the hydrophobic water-based polyurethane emulsion, modified titanium dioxide nanoparticles and auxiliary materials to prepare super-hydrophobic spray paint; S3, combine step S2 The prepared super-hydrophobic spray paint is evenly sprayed on the surface of the plastic rain boot blank, and after curing, the plastic rain boot is obtained. The surface of the plastic rain boots of the present invention is sprayed with a super-amphiphobic coating, and the modified super-amphiphobic coating is prepared from hydrophobic water-based polyurethane emulsion and modified titanium dioxide nanoparticles as the main raw materials, and the coating exhibits super-hydrophobicity and oleophobicity. Coated plastic rain boots are self-cleaning. |
