Functionally modified fly ash zeolite-geopolymeric material was developed as cooling coatings for structural application. The tailored precursor of cool coating materials was obtained through modified grain behavior of zeolite with variable pour morphology and mechanical activation of fly ash followed by geopolymerization with alkaline activator. The modified zeolite was found to possess unique heat management properties through disorderly connected pores. The solar temperature profile showed a temperature variance of 4-6 °C for solar radiation. The samples showed a high solar reflective index (SRI) due to absorbance and less heat retention followed by cooling behavior in the sunshine.
功能改性粉煤灰沸石地质聚合物材料被开发用作结构应用的冷却涂层。通过改变沸石的颗粒行为、可变的倾倒形态以及粉煤灰的机械活化，随后与碱性活化剂进行地质聚合，获得了定制的冷却涂层材料前驱体。发现改性沸石通过无序连通的孔隙具有独特的热管理特性。太阳温度曲线显示，太阳辐射下温度变化为4-6°C。由于吸收率低且蓄热少，样品在阳光下具有冷却行为，因而显示出高太阳能反射指数（SRI）。
