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.

Description

technical field [0001] The invention relates to a preparation method and product of an airgel / non-fabric composite fire-proof and heat-insulating material with different surface hydrophilic and hydrophobic properties and flexibility, and particularly relates to a combination of silicon alkoxide compounds, silica gel compounds and The silica gel-silicon aerogel-silane coupling agent three-mix airgel sol solution system of silane coupling agent compound; soak a non-fabric in this three-mix airgel sol solution, so that the aforementioned airgel sol solution is evenly interspersed in the In this non-woven fabric, go through a drying process again to obtain an airgel / non-woven composite material that can have different hydrophilic and hydrophobic surface properties and has softness. This material can be applied to heat insulation materials for high-temperature equipment or building structures. Indoor insulation and fireproof board materials. Background technique [0002] Press, ...
