| titleOfInvention | Method for preparing zirconia aerogel material |
| abstract | The invention discloses a method for preparing a zirconia aerogel material. Zirconium tetrachloride is used as a precursor, a mixed solution of absolute ethyl alcohol and distilled water is used as a solvent, epoxypropane is used as an inductive agent of net gel, ethyl acetoacetate is used as a complexing agent, polyacrylic acid is used as a modifier, formamide is used as a chemical drying and controlling additive, and the zirconia aerogel material is prepared by virtue of the drying at the normal temperature in a sol-gel method. The preparation process is simple, zirconium tetrachloride which is low in price is used as the precursor, and the zirconia aerogel is prepared by adopting a normal pressure drying method, so that the weaknesses of the supercritical drying method that the cost is high, the danger is high and the mass production is not facilitated can be overcome; and moreover, the flexible organic high-molecular modifier is used for the modification in an in-site method, the resilience of the gel is improved, the damage of the aerogel structure due to the capillary force in the normal-pressure drying process is reduced, and the method has the characteristics of low production cost. |
