| 目的 研制具备高紫外光阻隔率、高红外光阻隔率、高可见光透射率的太阳隔热膜。 方法 依据标准大气光谱和隔热膜的基本原理给出理想隔热膜的透射率光谱曲线,在防止室内眩光的基础上给出太阳隔热膜的实用透射率曲线。 通过对金属 Ag 薄膜光学常数的研究,提出基于介质 ZnS 和金属 Ag 的多层结构的选择反射型太阳隔热膜结构,利用 TFC 膜系软件设计三层结构的选择反射型太阳隔热膜并进行允差分析。 采用热蒸发技术制备该选择反射型膜太阳隔热膜。 结果 隔热膜在 0. 3 ~0. 38 μm 紫外波段的阻隔率达到 99. 2% ,在 0. 38 ~0. 78 μm 可见光波段的平均透射率为 75. 2% ,在 0. 78 ~ 2. 5 μm 红外波段的阻隔率达到 91. 2% ,太阳能总隔热率为 62. 1% 。 结论 研制的太阳隔热膜能在保证隔离紫外线辐射和红外热辐射的同时满足对可见光具有较高的透射率。 |

| 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-layer 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 insulation 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 insulation 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. |
