Abstract

The invention discloses a high transmittance and high reflection heat insulation film. The heat insulation film comprises a first high refractivity film layer, a first low refractivity film layer, a second high refractivity film layer, a second low refractivity film layer, a third high refractivity film layer, a third low refractivity film layer, a fourth high refractivity film layer, a fourth low refractivity film layer, a fifth high refractivity film layer and an antireflection film layer that are stacked in order from the bottom up. All the high refractivity film layers have a thickness of 100-150nm and a refractive index of 2.1-2.4; all the low refractivity film layers have a thickness of 180-250nm and a refractive index of 1.3-1.5nm; and the antireflection film layer has a thickness of 150-500nm. The nine film layers with different high and low refractive indexes are staggered and stacked in order to form an infrared reflective layer, the infrared reflectivity can be improved, then the antireflection layer is compounded to form a heat insulation film so as to improve the transmittance of the whole film layers. All the film layers do not use any metal plating, and the mobile phone signal shielding phenomenon is effectively solved.

Description

technical field [0001] The invention relates to the technical field of composite heat-insulating films, in particular to a heat-insulating film with high transmission and high reflection. Background technique [0002] Thermal insulation window film is a film material that selectively reflects, absorbs and effectively blocks the infrared light in sunlight. It is mainly used to paste on the surface of automobile glass windows and building doors and windows to achieve the effect of heat insulation and energy saving. Because it is non-polluting, convenient to mount and replace, it has broad market development prospects. [0003] Although there are many kinds of heat insulation films on the market, it is difficult to take into account high light transmittance and good heat insulation performance. The film disclosed in "Magnetron sputtering film with high light transmission and high heat insulation" (publication number CN 202623428U) includes a PET layer, a silver layer and an AT...
