The invention discloses a self-repairing thermoplastic polyurethane heat-insulating film, a preparation method and application thereof. The heat insulation film is composed of a thermoplastic polyurethane film layer, a metal heat insulation layer and a self-repairing coating in sequence; wherein, the raw material formula of the thermoplastic polyurethane film layer includes: TPU masterbatch and modified nano-indium antimony oxide; The metal heat insulation layer is a mixed heat insulation layer of metal material and nano-tungsten oxide, and the metal material is metal element and/or metal oxide. The heat insulation film of the present invention has good heat insulation performance, can reduce light transmission and heat transfer, produce heat insulation, flame retardancy and wear resistance effects, and has self-repair function, good scratch resistance performance, and has advantages in the aspect of automobile safety protection film. Wide application prospects. |
