Low-dielectric and low-heat-conduction aerogel composite material and preparation method thereof
The invention discloses a low-dielectric and low-heat-conduction aerogel composite material and a preparation method thereof, the aerogel composite material is suspended and dispersed in a trace alcohol-containing aqueous solution to form a trace alcohol-containing aerogel suspension powder solution, the aerogel suspension powder solution can be uniformly compounded with various fiber blankets or fiber mats, and then a low-cost and low-dielectric aerogel composite heat insulation blanket is formed by solvent recovery and drying. The method comprises the steps of mixed hydrolysis, suspension dispersion of a condensation solution, composite molding and solvent recovery and drying. According to the technology, a large number of hydrophobic organic solvents and interfacial active agents are not added, and in the suspension dispersion condensation process, a large number of micro-alcohol-containing aqueous solutions are combined with an emulsifying machine to directly suspend and disperse a hydrophobic or hydrophilic-hydrophobic complex aerogel dispersion solution; then, the aerogel is compounded with various fiber blankets or mats through the technologies of pressure suction, impregnation or spraying and the like, and the aerogel composite material is dried and the solvent is recycled and reused through the normal-pressure drying and recycling technology.
本发明公开了一种低介电、低热传导气凝胶复合材及其制备方法，在含微量醇类水溶液悬浮分散以形成含微量醇类气凝胶悬浮粉体溶液，可与各类纤维毯或纤维席均匀复合，随后溶剂回收干燥形成一种低成本、低介电气凝胶复合隔热毯，其步骤包含混合水解、悬浮分散缩合溶液、复合成型及溶剂回收干燥。本技术不添加大量疏水性有机溶剂及界面活性剂，且在悬浮分散缩合中利用大量微含醇类水溶液结合乳化机进行直接悬浮分散疏水性或亲水‑疏水复数气凝胶分散溶液，随后利用压吸、含浸或喷淋等技术将气凝胶与各类纤维毯或席复合，以常压干燥回收技术进行气凝胶复合材料的干燥及溶剂回收再利用。
