| titleOfInvention | Aerogel composite material and preparation method thereof |
| abstract | The invention provides a preparation method of an aerogel composite material, which comprises the following steps: mixing melamine and formaldehyde, adding aerogel under the condition of stirring the formaldehyde-melamine mixture, and heating the formaldehyde-melamine-aerogel mixture to prepare a melamine prepolymer; mixing the melamine prepolymer with a hardening agent, a foaming agent and deionized water to prepare a foaming liquid; foaming the foaming liquid to obtain a foaming body, curing and annealing to prepare the aerogel modified melamine foam. The invention also provides the aerogel composite material prepared by the preparation method. The embodiment of the invention utilizes the characteristics of small grain size and porous melamine of the aerogel to complement each other, can obviously improve the heat conductivity coefficient, and simultaneously improves the defects of brittleness and frangibility of the aerogel. |
