Embodiment 1
[0034] Preliminary preparation of reagents:
[0035]Preparation of composite airgel particles: Mix furfural, water-soluble phenolic resin, sepiolite powder and water at a mass ratio of 5:1:0.5:100, stir evenly to obtain a mixed solution, and mix the concentration of 0.5mol / Add L of ammonia water dropwise to the mixed solution until the mixed solution is neutral; then react at 60°C for 15 hours to obtain a composite carbon sol; mix the composite carbon sol and titanium dioxide sol at a mass ratio of 1:1, and mix well to obtain a mixed sol , after aging the mixed sol at room temperature for 1.5 days, the mixed sol solvent was replaced with absolute ethanol for 18 hours, and then the mixed sol was replaced with n-hexane for 9 hours, and the composite gel was obtained after removing the n-hexane; finally, carbon dioxide was used to Composite airgel particles are obtained by pulverizing the composite gel after being dried by the supercritical fluid.
