浅析SiO_(2)气凝胶材料在超低能耗建筑中的应用

Analysis on Application of SiO_(2)Aerogel Materials in Ultra-low Energy Buildings

被动式超低能耗建筑助力绿色转型,已经是未来建筑发展的趋势。但目前市场上的被动式超低能耗建筑外墙保温材料是以建筑节能75%标准设计,一是不能满足节能率达到90%以上的超低能耗建筑技术要求,二是阻燃等级以B级为主,存在很大的安全隐患。气凝胶作为一种多功能的高效保温隔热环保材料,在建筑领域的应用研究逐渐受到广泛关注。本文主要针对SiO_(2)气凝胶保温隔热材料在外墙保温系统应用的特点作了分析和总结,对推动气凝胶材料在被动式超低能耗建筑领域的发展提供参考。

Passive and ultra-low energy buildings help green upgrade the construction industry,are already an inevitable trend of future building development.However,the current external wall insulation materials of passive and ultra-low energy buildings on the market are designed based on the building energy saving 75%standard,which can not meet the technical requirements of ultra-low energy buildings with an energy saving rate of more than 90%.The flame retardant grade is mainly grade B,which has great security risks.Aerogels,as a kind of multi-functional and environment-friendly materials with high-efficiency thermal insulation,have been widely concerned about their application in the field of construction.This paper mainly analyzes and summarizes the characteristics of the application of SiO_(2)aerogel thermal insulation materials in exterior wall thermal insulation systems,which could provide reference for promoting the development of aerogel materials in the field of passive and ultra-low energy buildings.
