本文主要研究轻薄屋面浅色降温的机理和隔热防水涂料的研制。通过大量的试验资料证明:浅色屋面的外表面温度可比黑色屋面降低20～30℃,从而改善了轻薄屋盖的隔热效果。屋面隔热防水涂层是一种既能隔热又能防水的复合涂层,具有良好的耐水、耐碱、耐热、耐裂、耐老化和耐污染性能。隔热防水涂料无毒,可冷作业,原料易得,成本较低,为我国增添了一种新的屋面隔热防水材料。
This paper mainly studies the mechanism of light-colored cooling of light and thin roofs and the development of heat-insulating waterproof coatings. Through a large amount of test data, it is proved that the temperature of the outer surface of the light-colored roof can be reduced by 20-30°C compared to the black roof, thereby improving the heat insulation effect of the light and thin roof. Roof insulation waterproof coating is a kind of composite coating which can not only heat insulation but also waterproof. It has good water resistance, alkali resistance, heat resistance, crack resistance, aging resistance and pollution resistance. Insulation waterproof coating is nontoxic, cold workable, easy to obtain raw materials, and low cost, adding a new type of roof insulation and waterproof material to our country.
