Rapid modification preparation method of ultrathin aerogel composite material

The invention discloses a rapid modification preparation method of an ultrathin aerogel composite material, which is characterized in that sol-gel production is carried out by adopting a mode of simultaneously dipping glue and rolling, the conditions of non-uniform dipping of a base material and mottles on the surface of a product are effectively solved, and meanwhile, the thickness of the product is strictly controlled. An atomization spraying system is adopted in the modification process, modification liquid is directly sprayed on the surface of the wet gel, the hydrophobic modification time of the wet gel can be shortened, the production efficiency of the product is effectively improved, and good practical value and wide application prospects are achieved. 本发明公开了一种超薄气凝胶复合材料快速改性制备方法，采用边浸胶边收卷的方式进行溶胶凝胶生产，有效解决了基材浸胶不均匀和产品表面出现花斑的情况，同时严格的控制了产品的厚度。在改性工序中采用了雾化喷淋系统，直接将改性液喷淋在湿凝胶表面，可以缩短湿凝胶疏水化改性时间，有效提高了产品的生产效率，具有良好的实用价值和广阔的应用前景。
