Abstract

Abstract:

Inorganic silica aerogels have broad application potential in energy saving and carbon reduction in aerospace,aviation,industrial and construction fields due to their ultra-low thermal conductivity,nonflammability of class A,low mo-isture absorption rate and light weight.However,poor mechanical property and high preparation cost limit the development and application of silica aerogels.The research progress of preparation technology of silica aerogel insulation materials was introduced.The application forms of silica aerogels in building field（such as super light aerogel foam concrete,super high performance aerogel insulation board,ultra-low heat transfer coefficient aerogel energy-saving glass） were reviewed,and the development trend of silica aerogels in building energy conservation was prospected.In response to the goal of carbon neutral development,with the development and cost reduction of aerogel preparation technology,silica aerogel insulation materials would be widely applied in building insulation,and at the same time,more functional requirements were put forward for their performance.Therefore,more systematic basic research and engineering application technology research are needed for silica aerogel materials to promote energy conservation,carbon reduction and sustainable development in the field of construction.
