Abstract
Przedmiotem zgłoszenia jest sposób wytwarzania aerożeli krzemionkowych, metodą zol - żel, przez hydrolizę tetraalkoksysilanu i kondensację produktu hydrolizy oraz hydrofobizację produktu przez sililowanie, następnie poddanie żelu procesowi starzenia i suszenie, który polega na tym, że wprowadza się do mieszaniny reakcyjnej na etapie powstawania żelu krzemionkowego, a jako czynnik sililujący stosuje się co najmniej jeden z grupy: heksametylodisilazan, heksametylodisiloksan, tri-n-butylometoksysilan, zaś suszenie żelu krzemionkowego prowadzi się pod ciśnieniem atmosferycznym.The subject of the application is a method of producing silica aerogels, by the sol-gel method, by hydrolysis of tetraalkoxysilane and condensation of the hydrolysis product, and hydrophobization of the product by silylation, followed by gel aging and drying, which consists in entering the reaction mixture at the stage of silica gel formation , and as a silylating agent at least one of the group is used: hexamethyldisilazane, hexamethyldisiloxane, tri-n-butylmethoxysilane, and drying of the silica gel is carried out at atmospheric pressure.
