Aerogel composite powder and preparation method thereof
The invention provides aerogel composite powder, which is composed of the following raw materials: aerogel, polymer resin and pressure-resistant hollow nanospheres, the inner layer of the aerogel composite powder is aerogel and silicon dioxide hollow nanospheres, and the silicon dioxide hollow nanospheres are filled in the pores of the aerogel. Aerogel holes are filled with the silicon dioxide hollow nano-microspheres, so that the silicon dioxide can support the aerogel holes, and collapse of the aerogel holes caused by various reasons in the use process of the aerogel is prevented; the aerogel and the silicon dioxide hollow nano-microspheres are wrapped by high-molecular resin, so that the mechanical strength of the aerogel can be enhanced; the silicon dioxide hollow nano microspheres are combined with the aerogel, so that the negative influence of other materials on the overall heat insulation performance of the composite material when the aerogel is compounded with the other materials can be reduced, and the better heat insulation performance of the aerogel composite powder is kept.
本发明提供了一种气凝胶复合粉体，由以下原料组成：气凝胶、高分子树脂和耐压空心纳米球，所述气凝胶复合粉体内层为气凝胶和二氧化硅空心纳米微球，二氧化硅空心纳米微球填充于气凝胶孔隙。使用二氧化硅空心纳米微球填充气凝胶孔洞，可以实现二氧化硅对气凝胶孔洞的支撑，防止气凝胶在使用过程中各种原因导致的气凝胶孔洞塌缩；使用高分子树脂对气凝胶和二氧化硅空心纳米微球进行包裹，可以增强气凝胶的机械强度；使用二氧化硅空心纳米微球与气凝胶进行组合，可以减少气凝胶与其他材料复合时其他材料对复合材料整体隔热性能的负影响，保持气凝胶复合粉体较好的隔热性能。
