摘    要:SiO2气凝胶由于其独特的纳米多孔结构及超低的导热系数引起人们广泛关注。以纤维毡为基材与SiO2气凝胶复合,经表面修饰和常压干燥制成的超低导热系数保温隔热材料,既保留了纯气凝胶独特的纳米孔结构及超低的导热系数,又大幅度提高了机械强度,扩展了其在保温隔热领域的应用。该材料常温常压下导热系数小于0.025W/(m·K),抗压强度大于2MPa,是一种新颖的优质保温隔热材料。

关 键 词:纤维毡  常压干燥  纳米SiO2气凝胶  超低导热系数  保温隔热材料

Abstract:SiO2 aerogels because of its unique nano-porous structure and ultra-low thermal conductivity causes widespread concern. Make thermal insulation material with ultra-low thermal conductivity by using fiber felt as the substrate to compound with SiO2 aerogels and drying at ambient pressure with surface modification. The material not only retains the unique nano-pore structure and ultra-low thermal conductivity of the pure aerogels,but also significantly increased the mechanical strength. It expands the applica...
Keywords:fiber felt  ambient pressure drying  SiO2 nano-porous aerogels  ultra-low thermal conductivity  thermal insulation material
