| 摘要 |
An inorganic-organic plastic having improved strength, elasticity, dimensional stability with increase in temperature and flame resistance and adapted for use in filling cracks and cavities and for making materials useful in the building industry is prepared by (1) premixing (c) an organic compound having at least one reactive hydrogen and at least one ionic group or at least one non-ionic hydrophilic group with (b) an aqueous silicate and then mixing the resulting mixture with (a) an organic polyisocyanate or (2) mixing (a), (b) and (c) simultaneously and reacting the mixture thus obtained to form a colloidal xerosol. |
