| description | The invention relates to a preparation method for a foaming-cement reinforced SiO2-TiO2 composite aerogel material. The method comprises the following steps: firstly, preparing a silica sol and preparing a titanium sol, then compounding the above two sols, compounding foaming cement through a vacuum impregnation method, performing aging on a gel, and performing drying treatment to obtain the aerogel material. According to the invention, a synchronous sol process is used to realize mixing of a SiO2 aerogel component and a TiO2 aerogel component at the molecular level, and TiO2 is used as an opacifier to be uniformly compounded in a SiO2 aerogel system in situ, so that better shielding effects on infrared heat radiation under a high temperature are realized, and thermal insulation performance of an aerogel material under the high temperature is effectively improved; meanwhile, the foaming cement is used as a reinforcing phase to be compounded with a silicon-titanium binary aerogel, so that the defect that the a |
