摘　　要：文章简要介绍了超临界和常压干燥制备SiO_2气凝胶的工艺技术,对这两种工艺制备的气凝胶性能指标进行了比较。并简要概述在工厂化生产中,这两种方案的优缺点,并提出适应工厂化生产气凝胶的工艺。文章系统的归纳了气凝胶国内外的研究成果,着重列举了气凝胶在建筑保温中的应用,并对产业化应用进程提出了更好的展望。In this paper, the process technology of the preparation of SiO2 aerogel by supercritical and atmospheric drying is introduced. The performance indexes of the aerogel prepared by these two processes are compared. This paper briefly outlines the advantages and disadvantages of these two schemes in factory production, and puts forward the latest process of adapting to factory production. This paper summarizes the latest research results of airgel at home and abroad, focusing on the use of airgel in building insulation, and it also puts forward a better prospect of industrialization application.
