摘    要:以超薄纳米隔热材料为间隔物、金属箔为反射层制备了多层反射纳米隔热材料,通过改变隔热材料的组合结构测试其隔热效果.结果表明:在研究范围内增加不锈钢箔层数、将不锈钢箔放置在低温区或在低温区用铝箔替代不锈钢箔都对隔热效果有利;测试温度高时隔热效果更好.

关 键 词:多层反射纳米隔热材料  组合结构  隔热效果

Abstract:Multi-layered nanoporous-insulation materials were prepared with thin nanoporous-insulation materials and metallic foils,Insulation performance of different structures were tested.The results indicated that using more metallic foil layers,placing stainless steel in low temperature zone,or using aluminum foil instead of stainless steel foil in low temperature zone and testing at higher temperature were of advantage to insulation performance.
Keywords:Multi-layered nanoporous-insulation materials  Structure  Insulation performance
