摘要： 以气凝胶为隔热功能组分，通过模板涂覆法研制了几款不同规格的双面格栅结构的气凝胶隔热毡。使用数字式透气测量仪与热平板法分别对双面格栅气凝胶隔热毡的透气性能与热防护性能进行了测试表征，并对双面格栅气凝胶隔热毡的热防护机理进行了分析，研究结果表明，气凝胶的添加以及面料结构的优化显著提升了消防服隔热面料的热防护性能，并在很大程度上改善了气凝胶复合面料的透气性能。双面格栅气凝胶隔热毡的透气性能与格栅缝隙长度成正比关系，但与格栅厚度无显著关系。其中，当格栅厚度为0.5 mm，宽度为2.5 mm 时，双面格栅气凝胶隔热毡的综合性能最佳，透气率为138.91 mm/s，组合面料内外侧温差相比未涂层时提高了近40 ℃。

Abstract: Using aerogel as a heat- insulating functional component, several types of aerogel insulation felts with double-sided grille structure of different specifications were developed by template coating method.The air permeability and thermal protection performance of the double- sided grid aerogel insulation felt were measured and characterized by the digital air permeability meter and the hot plate method respectively，then the thermal protection mechanism was analyzed.The results show that the addition of aerogel and the optimized design of the fabric structure significantly improve the thermal protection performance of the fire protection thermal insulation fabric, and decrease the reduction of air permeability to the greatest extent. Moreover, the study shows that there is no significant correlation between the air permeability and the thickness of the coating, but the air permeability is directly proportional to the gap length of the grid.Among them, the aerogel coating with a thickness of 0.5 mm and a width of 2.5 mm has the best comprehensive performance, the air permeability is 138.91 mm/s, and the temperature difference between the inside and outside was increased by nearly 40 ℃ compared with uncoated fabric.
