ABSTRACT:Objective To develop a solar heat insulation film with high UV blocking rate, high infrared blocking rate and high visible light transmittance. Methods The ideal transmittance spectral curve of solar heat insulation film was given according to the principle of heat insulation and the standard atmosphere spectrum. The practical transmittance spectral curve of solar heat insulation film was also given to prevent the glare. The optical constant of metal Ag thin film was studied, and the spectral selective reflection solar heat insulation film with multilayer structure based on the medium zinc sulfide ( ZnS) and metal Ag was presented. Three-lay-er solar heat insulation film was designed using TFC software, and tolerance analysis was performed. The solar heat insulation film was deposited by thermal evaporation technique. Results The spectral test results showed that the UV blocking rate of the heat in-sulation film reached 99. 2% in the range of 0. 3~0. 38 μm, the average transmittance was more than 75. 2% in the visible wave-length range of 0. 38~0. 78 μm and the infrared blocking rate was 91. 2% in the range of 0. 78~2. 5 μm. The total solar heat in- <br> sulation rate was 62. 1%. Conclusion The heat insulation film developed could isolate UV radiation and infrared radiation, and meanwhile had high transmittance in the visible waveband.
