摘要
气凝胶作为一种连续三维网络纳米多孔结构物质,具有比表面积大、孔隙率高、密度低、热导率低等特点,其通常与无机纤维等复合,制备成气凝胶复合制品。本文通过研究气凝胶复合制品在绝热、防火和耐高温等方面的表现,阐明其在建筑领域应用的可行性。
As continuous three-dimensional network nanoporous materials, aerogels have large specific surface area, high porosity, low density and excellent thermal insulation properties. In practical applications, aerogels are usually compounded with inorganic fibers etc. and become reinforced aerogel products. This paper studies the performance of aerogel composite products in terms of thermal insulation properties, fire performance and high temperature resistance, and expounds the feasibility of its application in the field of building.
