High ultraviolet reflectance energy-saving film used for airplane windscreen and preparation method thereof

The invention discloses a high ultraviolet reflectance energy-saving film used for an airplane windscreen and a preparation method of the high ultraviolet reflectance energy-saving film. The high ultraviolet reflectance energy-saving film comprises a windscreen substrate, an internal silicon oxide layer, a high ultraviolet reflectance layer, an energy saving layer and an external silicon oxide layer, wherein the internal silicon oxide layer, the high ultraviolet reflectance layer, the energy saving layer and the external silicon oxide layer are arranged on the windscreen substrate from inside to outside sequentially. The windscreen substrate is an airplane windscreen substrate. The thin film is good in visible light transmittance, high in ultraviolet reflectivity and infrared reflectivity and simple in production process, is favorable for independent adjustment of the parameter performance of a film system, and is excellent in corrosion resistance and weather fastness.
