| titleOfInvention | A kind of preparation method of rigid structure enhancing phenolic aldehyde aeroge heatshield material |
| abstract | A kind of preparation method of rigid structure enhancing phenolic aldehyde aeroge heatshield material, phenolic resin is dissolved in solvent in vacuum impregnation container first and forms novolac solution, then three-dimensional fibrous structure is pressed into phenol resin solution, to vacuum impregnation container vacuum-pumping.After a period of time, open closure and keep air pressure unobstructed with the external world and stand a period of time.Three-dimensional fibrous structure is then taken out, is put into baking oven and is dried, hot setting forms a kind of rigid three-dimensional fibrous structure.Then resorcinol, furfural, ethanol and sodium hydroxide are mixed in proportion to form reactant solution in vacuum impregnation container, then rigid three-dimensional fibrous structure is pressed into solution, again to vacuum impregnation container vacuum-pumping, after being kept for a period of time, vacuum impregnation container is put into baking oven and carries out collosol and gel.Finally, the three-dimensional fibrous structure containing gel is taken out after drying, obtains the phenolic aldehyde aerogel products of rigid structure enhancing. |
