Application of Building Energy-saving Technology Based on SiO2 Aerogel Thermal Insulation Materials
摘要
Abstract
SiO2 aerogel is a kind of solid material with three-dimensional network structure, which has low density, low thermal conductivity, high transmittance, high porosity and high specific surface area as well as the character of fire prevention and water-proof, etc. Therefore, it is a rare lightweight, multifunctional and environmental protection material, which especially has a broad application prospect in the field of building thermal insulation. In this paper, the building energy efficiency was the target. The re-searches of SiO2 aerogel were briefly reviewed. The possibility of its mass production application was discussed from the aspects of variation of preparation of raw materials species and the cost reduction of raw materials and drying. And the paper mainly focused on the application research progress of heat preservation and heat insulation in construction using SiO2 aerogel glass, SiO2 aerogel insulation coatings, SiO2 aerogel fiber composites and SiO2 aerogel materials such as concrete and mortar. Then in view of its excel-lent properties, the idea of application of SiO2 aerogel material in building energy efficiency technology was put forward. The advan-tages of SiO2 aerogel materials in thermal insulation, waterproof, fire prevention performance and simplify the construction technolo-gy and so on were discussed. The building energy conservation system was built by using SiO2 aerogel material to replace the cur-rent building thermal insulation materials. Finally, the application prospect of SiO2 aerogel materials in the building heat preserva-tion and heat insulation was proposed.关键词
