Silica sol, silica aerogel felt manufactured using same, and method for manufacturing silica aerogel felt
The present invention provides a silica sol, a silica aerogel felt using the silica sol, and a method for manufacturing the silica aerogel felt, in which when the silica aerogel felt is manufactured, a catalyst composition contains a water repellent agent, a base catalyst, an organic solvent, and water, thus, an aging step, which is performed under high-temperature conditions and which increases the amount of solvent used, and a surface modification step, which uses a large amount of organic solvent and expensive surface modifier, are omitted, and the process is complicated and lengthy, thereby suppressing economic feasibility and productivity.
本发明提供一种二氧化硅溶胶、使用所述二氧化硅溶胶的二氧化硅气凝胶毡和制造所述二氧化硅气凝胶毡的方法，其中，当制造所述二氧化硅气凝胶毡时，催化剂组合物中包含疏水剂、碱催化剂、有机溶剂和水，从而可以省去在高温条件下进行并且增加溶剂的使用量的老化步骤，和使用大量的有机溶剂和昂贵的表面改性剂，并且其工艺复杂且冗长，从而抑制经济可行性和生产率的表面改步骤。
