Abstract
A method of preparing aerogels/nonwoven composites fireproof and heat-insulating materials with a hydrophobic or hydrophilic surfaces and includes steps as follows. A mixture solution in which alkoxysilane, silicones and silane coupling agents are mixed and stirred is instilled by acidic catalysts for a hydrolysis reaction during which a silane coupling agent solution is added for continuous stirring; a hydrous alkali catalytic (anhydrous alkali catalytic) organic solution is added in the mixture solution for a condensation reaction and development of a 'silicones-silica aerogels-silane coupling agents' aerogel mixture solution; a non-woven felt is impregnated with the mixture solution for development of soft hydrophobic (hydrophilic) aerogels/nonwoven composites fireproof and heat-insulating materials after curing and natural drying. The aerogels/nonwoven composites materials with softness and surface hydrophobicity/hydrophilicity available in mass production are applicable to thermal-insulating materials for high-temp industrial facilities or indoor heat-insulating and fireproof panels of a building structure.
