Problems solved by technology

Chinese patent CN102774111A discloses a double-layer PET structure heat insulation film, and the heat insulation layer with gold, silver, nickel, titanium alloy as heat insulation medium is prepared by evaporation coating, and the heat insulation film system prepared has good heat insulation performance , has a good metal texture, but the metal film is easy to oxidize and shields electromagnetic signals
The heat insulation film prepared by this method has good heat insulation performance, but the nano ceramic heat insulation film can absorb infrared rays, so secondary radiation will occur, reducing the heat insulation performance
[0005] The thermal insulation rate of the single-layer magnetron sputtering film is low. In order to improve the thermal insulation rate of the magnetron sputtering film, multi-layer magnetron sputtering is usually required, resulting in increased production costs.
The magnetron sputtering film is a metal film, which can produce mirror reflection, and the visible light transmittance of the multilayer magnetron sputtering film is low

Description

technical field [0001] The present invention relates to a high-performance nano-composite heat-insulating film, especially a double-layer PET heat-insulating composite film based on nano-magnetron sputtering film / nano-tungsten trioxide; in addition, the present invention also discloses the aforementioned high-performance nano-composite The preparation method of heat insulation film. Background technique [0002] Heat insulation film, also known as "solar film", originated in the 1970s. Heat insulation film is widely recognized by the public and favored by people for its excellent heat insulation, low heat conduction, high permeability, and heat preservation performance. [0003] The development of thermal insulation film has gone through 5 generations. The first generation is a coating and composite process film, also called tea paper, which can only cover sunlight and does not have a heat insulation effect; the second generation is a "dyed film" that uses deep dyeing tech...
