Patent ID: 6916504

Claim:
A method for producing a composite material of inorganic materials and silicon compound-based binders, comprising precondensing with substoichiometric amounts of water per mole of silicon compound in the presence of basic or acidic catalysts, one or more silicon compounds of the general formula R n —Si—X 4−n in which any R's present are identical or different groups which cannot be split off hydrolytically, and X is one or more hydroxyl groups or one or more groups which can be split off hydrolytically and are identical or different, and n is a number between 0 and 3, applying a composition comprising the precondensed silicon compound in amounts of 1 to 30% by weight with a greater than stoichiometric amount of water to inorganic materials comprising bundles or strands of glass fibers and/or mineral fibers, and then molding the resultant binder-carrying inorganic materials into molded objects.
