METHODS OF PREPARING ORGANIC-INORGANIC HYBRID BINDER COMPOSITIONS AND NONWOVEN PRODUCTS.

摘要

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.
