An aqueous solution of a polyol containing a plurality of pendant hydroxyl groups is combined with an organooxysilane to produce curable an orgamc- morgamc hybrid binder composition The aqueous sol-gel composition results from the condensation between a silicate generated in situ through hydrolysis and condensation of the organooxysilane and the water-soluble polyol via hydroxyl groups on the polyol and silanol groups on the silicate The hybrid binder thus prepared are useful in producing non-woven products such as glass fiber products, polyester fiber products and mineral wool products.
Ce procédé consiste à combiner une solution aqueuse d'un polyol contenant une pluralité de groupes hydroxyle pendants, avec un organooxysilane, afin de produire une composition de liant hybride organique-inorganique. La composition aqueuse sol-gel résulte de la condensation entre un silicate généré in situ par hydrolyse et condensation de l'organooxysilane et du polyol soluble à l'eau par l'intermédiaire des groupes hydroxyle du poylol, et les groupes silanol du silicate. Les liants hybrides résultants peuvent être utilisés pour la production de produits non-tissés tels que produits de fibre de verre, produits de fibres polyester, et produits de laine minérale.
