Preparation method and application of 3D printing silicon dioxide composite aerogel component
The invention discloses a preparation method and application of a 3D printing silicon dioxide composite aerogel component, and belongs to the technical field of aerogel preparation. The preparation method comprises the following steps: mixing a silicon dioxide precursor solution, silicon dioxide gel slurry and a montmorillonite colloidal solution according to a certain proportion, and stirring to obtain uniform precursor wet gel suitable for direct writing 3D printing. And transferring the precursor wet gel to an ink writer, and installing the ink writer on a 3D printer to directly write and print a 3D wet gel component. And in the ammonia atmosphere, further curing the wet gel component, and carrying out ethanol exchange and supercritical drying to obtain the 3D aerogel component. The 3D printing aerogel is easy to prepare and good in forming.
3D打印二氧化硅复合气凝胶构件的制备方法及应用，属于气凝胶制备技术领域。将二氧化硅前驱体溶液、二氧化硅凝胶浆料与蒙脱土胶体溶液按照一定比例混合，搅拌至均匀的、适合直写3D打印的前驱体湿凝胶。将前驱体湿凝胶转移至墨水写入器，并安装在3D打印机直写打印出3D湿凝胶构件。在氨气氛围下，湿凝胶构件进一步固化，经乙醇交换和超临界干燥，得到3D气凝胶构件。本发明中3D打印气凝胶制备简单，成型好。
