摘　　要：为改善气凝胶复合材料的承压能力,设计了一种纸蜂窝作为夹层,两侧复合气凝胶复合材料的夹层板,并探究该夹层板能否取代聚氨酯泡沫,应用于冷库墙体保温夹层。利用导热系数仪测得的试验数据,对纸蜂窝、气凝胶复合材料、气凝胶纸蜂窝夹层板的隔热性能进行了分析,讨论材料厚度对气凝胶蜂窝夹层板导热性能的影响。结果表明:纸蜂窝的厚度较小时,气凝胶纸蜂窝夹层板的导热系数均低于聚氨酯泡沫板;当纸蜂窝厚度为10 mm、孔径为6 mm,气凝胶复合材料厚度为10 mm或15 mm时,气凝胶纸蜂窝夹层板的导热系数低于0.03 W/(m·K),满足我国保温隔热行业材料的使用要求。To improve the pressure bearing capacity of aerogel composites,a paper honeycomb was designed as a sandwich,and a sandwich panel composed of aerogel composite materials on both sides was designed to explore whether the sandwich panel could replace polyurethane foam and be applied to the insulation sandwich of the refrigeration house wall.The thermal insulation performance of paper honeycomb,aerogel composite and aerogel paper honeycomb sandwich panel was analyzed by the test data measured by the thermal conductivity meter,and the influence of material thickness on the thermal conductivity of aerogel honeycomb sandwich panel was discussed.The results found that when the thickness of the paper honeycomb was thin,the thermal conductivity of the aerogel paper honeycomb sandwich panel was lower than that of the polyurethane foam board.When the thickness of the paper honeycomb was 10 mm,the aperture size was 6 mm,and the thickness of the aerogel composite material was 10 mm or 15 mm,the thermal conductivity was lower than 0.03 W/(m·K),meeting the material requirements of thermal insulation industry in China.
