纳米多孔保温材料的研究及应用

Research and Application of Nanoporous Thermal Insulation Materials

对绝热、保温材料的保温机理,纳米多孔保温材料制备、改性及应用进行了分析与综述,为新型轻质纳米多孔保温材料的研发提供一定的参考。SiO2气凝胶绝热、保温性能良好,但SiO2气凝胶强度低、韧性差而限制了其直接作为绝热保温材料应用于绝热、保温工程,因而SiO2气凝胶的改性以增加其强度和韧性是未来一段时间的研究重点。

The thermal insulation mechanism of thermal insulation and thermal insulation materials,the preparation,modification and application of nanoporous thermal insulation materials were analyzed and reviewed,which provided a reference for the development of new lightweight nanoporous thermal insulation materials.SiO 2 aerogel has good thermal insulation and good thermal insulation performance,but SiO 2 aerogel has low strength and poor toughness,which limits its application as thermal insulation material to thermal insulation and thermal insulation engineering.Therefore,To modify SiO 2 aerogel to increase its strength and toughness is the focus of research for some time to come.
