Abstract: In our daily life, energy consumption on buildings is usually on a level of 30~40% of the total, thus it is vital and also meaningful for energy-saving if such a new-style material with excellent insulator would be used. SiO2 aerogel were prepared by sol-gel process at ambient pressure and have nano porous structure. Surface modification was used to adjust nano porous structure of the aerogel and decrease thermal conductor. Porosity and thermal conductor efficiency of the SiO2 aerogel is above 90% and 0.015w/k.w respective. The aerogel is a super-insulator material and composed with cement mortar that will become excellent energy- saving structural wallboard.
