摘　　要：为研究SiO2气凝胶对芳纶非织造布抗压、阻燃防护功能的影响,以芳纶非织造布为骨架材料,将SiO2气凝胶施加到芳纶非织造布表面,制备出SiO2气凝胶混杂芳纶非织造布防护材料。通过扫描电子显微镜对其结构形貌进行表征,借助万能材料试验机对其抗压性能进行分析,最后利用热常数分析仪和火焰手系统,测试并评估了制备的防护材料的阻燃隔热性能。结果表明:SiO2气凝胶以不同大小的块状、颗粒状填充进入芳纶非织造布纤维间的空隙;SiO2气凝胶可增强芳纶非织造布的抗压性能,且降低其导热系数;混杂SiO2气凝胶后芳纶非织造布总的吸收能量值降低,说明SiO2气凝胶可明显增强芳纶非织造布的热防护效果。In order to research the effect of SiO2 aerogel on the anti-pressure,flame retardant protective functions of aramid nonwoven fabric,using aramid nonwoven fabric as the skeleton material,applying SiO2 aerogel to the surface of it,preparing SiO2 aerogel hybrid aramid nonwoven protective material.The structure was characterized by scanning electron microscopy,and its compression function was analyzed with a universal material testing machine.Finally,using the thermal constant analyzer and the flame hand system,the flame retardant insulation properties of the prepared protective materials were tested and evaluated.The results show that the SiO2 aerogel is filled into the gap between the fibers of the aramid nonwoven fabric in blocks or granules of different sizes.SiO2 aerogel can enhance the pressure resistance of aramid nonwoven fabric and reduce its thermal conductivity,the total absorbed energy value of the aramid nonwoven fabric is reduced after the hybrid SiO2 aerogel.It is illustrated that the SiO2 aerogel can significantly enhance the thermal protection effect of aramid nonwoven fabric.
