| titleOfInvention | Preparation method of bulk C-Al2O3 composite aerogel |
| abstract | The invention relates to a preparation method of bulk C-Al2O3 composite aerogel, belonging to the technical field of composite material preparation processes. The preparation method comprises the following steps: evenly stirring aluminum chloride crystal, water and ethanol so as to obtain a clear light yellow aluminum chloride crystal hydrolysis solution; adding formaldehyde, resorcinol, water, ethanol, epoxypropane and a reaction catalyst to the solution and evenly stirring so as to obtain a C-Al2tO3 composite aerogel sol solution, and standing and gelling; treating a sample with a CO2 supercritical or ethanol supercritical drying method; and finally, carrying out high-temperature thermal treatment on the sample so as to finally obtain the bulk C-Al2O3 composite aerogel. In the preparation method provided by the invention, a cheap inorganic salt is used as an aluminum source and is introduced into carbon aerogel with good mechanical property, preparation process is easy to operate, the prepared aerogel has the advantages of high completeness, large specific surface area, complete structure, low heat conductivity, low density, large strength and the like, and the system has good application prospect and infinite potential in the aspect of a high-temperature heat-insulation material with the temperature of above 1000 DEG C. |
