Abstract

The invention relates to a high-transmission and high-reflection heat insulation film. The heat insulation film comprises a high light transmittance substrate layer (10), and an infrared absorbing layer (20), an infrared reflection layer (30) and an anti-reflection film (40) are laminated on the substrate layer (10); the infrared reflection layer (30) comprises at least one infrared reflection unit, and every infrared reflection unit comprises a metal layer (31), a protective layer (32), a high refractive index film (33) and a low refractive index film (34) which are laminated from bottom to top; the refractive index of the high refractive index film (33) is 2.1-2.5, and the refractive index of the low refractive index film (34) is 1.3-1.6; and the thickness of the metal layer (31) is 5-25nm, and the protective layer (32) can prevent the metal of the metal layer (31) from being oxidized. Three shielding or blocking methods of infrared reflection, infrared refraction interference and infrared absorption are combined, so the heat insulation film integrates the advantages of the three shielding methods, and the heat insulation performance is greatly improved. The anti-reflection layer increases the transmittance of visible lights, and meets the requirements for clear vision and irradiance in applications.

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] In order to avoid the high temperature in the closed environment due to sunlight without affecting the line of sight and lighting effects, it is often necessary to paste heat insulation films on transparent doors and windows, such as car window glass (including car window front glass) and high-rise buildings. Paste the heat insulation film to provide a comfortable temperature, especially in summer, which can reduce the indoor temperature of the building and save the power consumption of the air conditioner. The heat insulation film not only needs to have the effect of heat insulation, but also has sufficient transmittance, so as not to affect the line of sight and lighting. We know that it is mainly infrared or near-infrared light that can bring heat. If infra...
