Research on the Reinforcement of SiO2 Aerogel and Its Application in the Field of Building Materials
Aerogel is a kind of synthetic porous material,which has significantly lower thermal conductivity than other commercial thermal insulation materials,and has special physical and chemical properties.Therefore,it is considered as one of the most promising building insulation materials.This paper summarizes the preparation process of silica-based aerogel materials,the reinforcement and modification technology,and the research and application status of SiO2 aerogel in the field of building materials(such as insulation board(felt),cement,mortar,concrete,glass system,solar collector cover,etc.).At the end of this paper,the research trend of aerogel composites in the future research,production and application is prospected.
