PCT No. PCT/HU92/00022 Sec. 371 Date Jan. 19, 1994 Sec. 102(e) Date Jan. 19, 1994 PCT Filed May 18, 1992 PCT Pub. No. WO92/21713 PCT Pub. Date Dec. 10, 1992The invention relates to novel polysilicic acid/polyisocyanate basic materials, binding materials and foams with improved mechanical properties as well as a higher resistance against heat and chemicals. It is characteristic of the new base materials that they are built up (composed) of - 100 parts by mass of a polyisocyanate, - 50-400 parts by mass of a polysilicic acid component, - 0.5-70 parts by mass of phosphoric acid triesters and/or salts of - phosphoric acid mono- and/or diesters formed with - amines and/or alkaline metals, - and optionally - 0-5 parts by mass of a catalysts containing a tertiary amino - group, - 0-50 parts by mass of a reactive diluent, - 0-10 parts by mass of tenside(s) - as well as 0-400% by mass of fillers and optionally other auxiliaries, calculated for the total mass (=100%) of the components listed above. |
