摘要:

分别以硅酸铝纤维和玻璃纤维为骨架材料,采用溶胶-凝胶、常压干燥制得纤维复合二氧化硅气凝胶材料,并对材料进行了结构和性能的测试分析。结果表明,二氧化硅气凝胶附着于纤维表面,提高了材料力学强度。硅酸铝纤维复合二氧化硅气凝胶材料的隔音性能优于玻璃纤维复合二氧化硅气凝胶材料。两种纤维复合二氧化硅气凝胶材料耐高温、燃烧性能均达到A级。硅酸铝纤维复合二氧化硅气凝胶材料和玻璃纤维复合二氧化硅气凝胶材料的产烟毒性分别为AQ1级和AQ2级,导热系数分别为0.034 W/(m·K)和0.033 W/(m·K)。

Abstract:

The fiber composite silica aerogel materials were prepared using alumina silicate fiber or glass fiber as framework via sol-gel process and ambient pressure drying technology.The structure and properties of the produced materials were tested and analyzed.The results showed that silica aerogels were attached to the fiber surfaces which improve the mechanical properties of the materials.The sound insulation performance of alumina silicate fiber composite silica aerogel material was better than that of glass fiber composite silica aerogel material.The two kinds of fiber composite silica aerogel materials met the requirement of Level A on high thermal resistance and combustibility.The alumina silicate fiber composite silica aerogel material and glass fiber composite silica aerogel material met the requirement of Level AQ1 and Level AQ2 on smoke toxicity,respectively.And their thermal conductivities were 0.034 W/(m·K) and 0.033 W/(m·K),respectively.

Key words: silica aerogel, fiber, composite, fireproofing, heat insulation
