| titleOfInvention | Method for continuous preparation of core-shell hydrophobic bipolar composite aerogel powder |
| abstract | The invention relates to the field of aerogels, in particular to a method for continuously preparing core-shell hydrophobic bipolar composite aerogel powders. A preparation method of a core-shell hydrophilic bipolar composite aerogel powder is as follows: a mixing step: mixing a hydrophilic silicon alkoxide compound, a hydrophobic alkyl-substituted silicon alkoxide compound, and an organic mixed solvent to form a mixed solution; a hydrolysis step : Add acid catalyst to mixed solution to carry out hydrolysis reaction; Condensation and dispersion step: Add alkali catalyst to mixed solution to carry out condensation reaction, and add dispersing solvent during condensation reaction, and stir, so that mixed solution is phase-separated and mixed during the stirring process. Gelling to form core-shell hydrophobic bipolar aerogel particles. After filtration and drying, the core-shell hydrophobic bipolar aerogel powder can be obtained, thereby improving the overall preparation speed of core-shell hydrophobic bipolar aerogel particles and powder, improving the post-processing mixing efficiency and improving the thermal insulation effect of the product . |
