A preparation method of an energy-saving window film used for insulating glass sputters metals, metal oxides and nitrides on a surface of a high-strength base film in a layer-by-layer manner by a magnetron sputtering process, so as to reduce an infrared emissivity of film layers and effectively block an infrared transmission without affecting a daylighting field of vision; by coating a modified polyurethane acrylate protective layer on a surface of a low radiation layer, an oxidation resistance of the coating is improved; an installation adhesive layer provides an adhesion of the film to the glass, which can enhance the impact strength of the glass and play the role of safety and explosion-proof. The energy-saving window film is applied to the insulating glass with multiple functions such as impact resistance, lightness, energy-saving heat preservation, oxidation resistance, etc., which extends the overall service life of the insulating glass.
