Whisker reinforced silicon oxide aerogel thermal insulation material and preparation method thereof
The invention discloses a whisker-reinforced silicon oxide aerogel thermal insulation material and a preparation method thereof, and the whisker-reinforced silicon oxide aerogel thermal insulation material with high temperature resistance and low thermal conductivity is prepared by using low-cost aqueous silica sol as a silicon source and a ceramic whisker porous skeleton as a reinforcing phase through a simple process. The water-based silica sol with low price is adopted as a silicon source precursor, sol preparation only needs one step, the process is simple and does not need complicated processes such as concentration and solvent replacement, and the raw material and preparation process of the sol are low in cost.
本发明公开了一种晶须增强氧化硅气凝胶隔热材料及其制备方法，本发明采用低成本的水性硅溶胶作为硅源、陶瓷晶须多孔骨架作为增强相，以简单工艺制备耐高温、低热导的晶须增强氧化硅气凝胶隔热材料；采用价格低廉的水性硅溶胶作为硅源先驱体，溶胶配制仅需1步，工艺简单无需复杂的浓缩、溶剂置换等过程，溶胶的原料与配制工艺成本低。
