摘　　要：测试了具有低太阳吸收率、高发射率的碱土金属碳酸盐的炎热地区"晒不热"涂料在不同模拟屋面上的降温效果。结果显示,在不同的屋面材料上涂刷"晒不热"涂料的降温效果不同,其中在油毛毡上涂刷"晒不热"涂料降温效果最好,可降温10.8℃;在砂浆板上涂刷"晒不热"涂料降温效果最差,降温2.5℃。在铁皮箱上测试24h的循环实验,白天与日间曝晒试验相符合,而夜间温度则要比环境温度低1～2℃,在不同季节的同一屋面的测试效果具有重复性。The insolating-not-hot coating was made a test about its thermal effects on different roof cove ring, which was a carbonate of alkali metal material with low solar absorptance and high emittance. The results show that the insolating-not-hot coating on the different roof covering has different thermal effect. The insolating-not-hot coating on the asphaltic felt has the best thermal effect which can cool 10. 8℃ and the insolating-not-hot coating on the mortar has the least thermal effect which can cool 2. 5℃. The cycle experiment of twenty-four hours on iron trunk has the same thermal effects during the day and the temperature on iron trunk is 1--2℃ lower than the ambient temperature during the night. The insolating-not-hot coating on the same roof covering also has the same thermal effect in different seasons.
