| titleOfInvention | Method for producing polyol dispersions containing silica and use thereof for producing polyurethane materials |
| abstract | The present invention relates to a process for producing a silicate-containing polyol, (i) an aqueous silica sol (K) having an average particle diameter of 1 to 150 nm, a calculated silica content of 1 to 60% by weight, as SiO 2 , and a pH of 1 to 6, based on the SiO 2 content used, Butanol, 2-methyl-2-propanol, 1-chloro-2-propanol, cyclopentanol, cyclohexanol, 1,4-dioxane, Propanol, 2-ethoxyethanol, 2-methyl-2-propanol, 2-methoxyethanol, dimethylformamide, acetonitrile, dimethyl One or more organic solvents (L) (based on the amount of water) selected from the group consisting of sulfoxide, acetone, methyl ethyl ketone and ethyl acetate in an amount of 0.1 to 20 times, (ii) mixing the resulting mixture with a polyol, (iii) at least partially removing water and the organic solvent (L) by distillation, (iv) at least one compound (S) having at least an at least monoalkoxylated silyl group and at least an alkyl, cycloalkyl or aryl substituent which may contain a heteroatom, said substituent being selected from those which are reactive towards alcohols, amines or isocyanates (I), (ii) and (iv) in an amount of from 0.1 to 20 μmol per m 2 of surface area of (K) Can be continuously performed), (v) optionally adjusting the pH of the silica-containing polyol to a value of 7 to 12 by addition of a strong basic compound (step (v) may also be carried out between steps (iii) and (iv) To a manufacturing method comprising the steps of: |
