对现役消防服的隔热层材料和使用性能进行了分析,介绍了国内外多种新型隔热材料研究进展和应用现状.初步对比讨论了具有超低密度和热导率的SiO2气凝胶应用于消防服的可行性,指出,采用SiO2气凝胶作为隔热层的消防服综合导热系数仅为现役消防服的1/4,而重量仅为现役消防服的1/3.%This paper analyses the insulation material and performance of the active fire protective clothing. Introduces the research progress and application status of a variety of new heat insulation materials. It discusses the feasibility of using the SiO2aerogel that with ultra low density and thermal conductivity in the fire protective clothing. It is pointed out that, using SiO2aerogel as a thermal insulation layer, the total thermal conductivity is only 1/4,and the weight only 1/3 of the active fire protective clothing.
