Method for improving high-temperature heat insulation performance of nano-porous heat insulation material
The invention discloses a method for improving the high-temperature heat insulation performance of a nano porous heat insulation material. The method comprises the following steps: (1) preparing an aerogel composite material wet gel system; (2) preparing impregnation sol; (3) dipping aerogel composite material wet gel in the sol; the specific method of the sol-impregnated aerogel composite material wet gel comprises the following steps: putting aerogel composite material wet gel into an impregnation tank, pouring the prepared impregnation sol into the impregnation tank, completely immersing the wet gel, and after the aerogel composite material is fully impregnated by the impregnation sol and is gelled, carrying out solvent replacement on the aerogel composite material subjected to impregnation treatment; and (4) carrying out supercritical drying treatment on the composite part treated in the step (3).
本发明一种提高纳米多孔隔热材料高温隔热性能的方法，步骤如下：(1)制备气凝胶复合材料湿凝胶体系；(2)制备浸渍溶胶；(3)溶胶浸渍气凝胶复合材料湿凝胶；所述溶胶浸渍气凝胶复合材料湿凝胶的具体方法为：将气凝胶复合材料湿凝胶放在浸液槽中，将制备的浸渍溶胶倒入浸渍槽，完全浸没湿凝胶，待浸渍溶胶充分浸渍气凝胶复合材料并凝胶后，将浸渍处理后的气凝胶复合材料进行溶剂置换；(4)将步骤(3)处理后的复合件进行超临界干燥处理。
