Inorganic-organic composition

Abstract

Inorganic-organic compositions obtained from a mixture of components comprising: A. from 5-98% by weight of an organic polyisocyanate B. from 2-95% by weight of an aqueous alkali metal silicate solution containing about 20-70% by weight of said alkali metal silicate C. from 0-93% by weight of a water-binding component and D. from 1-30% by weight of a halogen or phosphorus containing compound, Based on the total weight of (a), (b), (c) with the proviso that when (c) is 0-20% by weight (a) contains 2-200 milliequivalents of ionic groups per 100 grams of said polyisocyanate. The products of the invention may be used in many forms including both porous and non-porous products as surface coatings having good adhesion and resistance to abrasion, as a mortar, and as a foam concrete for making molded products particularly in construction engineering and civil engineering as for building walls, igloos, road building and the like.
