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...
