摘要： 随着国家加快推进“双碳”战略，建筑领域低碳转型，导热系数极低的气凝胶材料快速发展。随着气凝胶制备技术的发展，气凝胶制品开始出现并得到应用。为了研究气凝胶制品的防火性能，探究其在防火建筑构件中的适用性，选取气凝胶复合防火玻璃和气凝胶膨胀珍珠岩门扇两种防火建筑构件，按照标准要求进行耐火性能等项目的测试。结果表明：气凝胶复合防火玻璃具有优越的耐热、耐寒以及耐紫外线辐照性能，在高温条件下，90 min内可保持耐火完整性，85 min时失去耐火隔热性；气凝胶膨胀珍珠岩产烟毒性和燃烧性能均符合GB 12955—2008《防火门》的要求，门扇在90 min内可以保持耐火隔热性。

Abstract: As the country accelerates the “dual carbon” strategy and low-carbon transformation in the construction field, aerogel materials with extremely low thermal conductivity develop rapidly. With the development of aerogel preparation technology, aerogel products began to appear and be applied. In order to study the fire resistance of aerogel products and explore their applicability in fire resistant building components, two fire resistant building components, aerogel composite fire resistant glass and aerogel expanded perlite door, were selected to test the fire resistance and other items according to the standard requirements. The results show, aerogel composite fire resistant glass has excellent heat resistance, cold resistance and ultraviolet radiation resistance. Under high temperature conditions, it can maintain fire integrity within 90 minutes, and lose fire resistance and heat insulation after 85 minutes. Aerogel expanded perlite smoke toxicity and combustion performance are in line with the requirements of GB 12955-2008,Fire Doors, and the doors can maintain fire insulation within 90 minutes.
