| titleOfInvention | A kind of polyurethane-silicon hybrid airgel and preparation method thereof |
| abstract | The present invention proposes a polyurethane-silicon hybrid airgel and a preparation method thereof. Under the catalysis of a polymerization catalyst, polyether diols and diisocyanates are polymerized to obtain isocyanate-terminated polyurethane oligomers. Aminosiloxane is obtained by obtaining siloxane-terminated polyurethane oligomer, adding an aqueous solution of a gel catalyst, gelling, aging the wet gel, and then replacing it with a solvent and supercritically drying it. Through a special preparation process, the present invention enables the obtained polyurethane-silicon hybrid airgel to have high resilience performance on the basis of ensuring high temperature performance, and solves the technical problem that the prior art cannot prepare high resilience aerogel. |
