PROCESS FOR THE IMPREGNATION OF MINERAL BUILDING MATERIALS AND DEVICE FOR CARRYING OUT THE PROCESS

Method for impregnating mineral building materials, with aqueous solutions of silanols and/or siloxanols is disclosed. The solution is obtained by continuous hydrolysis of alkoxysilanes and/or alkoxysiloxanes, of the general formula wherein R1=alkyl with 1 to 8 carbon atoms, at least 90% of the R1 g...

Beschreibung
Zusammenfassung:	Method for impregnating mineral building materials, with aqueous solutions of silanols and/or siloxanols is disclosed. The solution is obtained by continuous hydrolysis of alkoxysilanes and/or alkoxysiloxanes, of the general formula wherein R1=alkyl with 1 to 8 carbon atoms, at least 90% of the R1 groups in the average molecule being alkyl groups with 1 to 4 carbon atoms, R2=methyl or ethyl, a=0 to 1.5, b=1.0 to 4.0, a+b=2.0 to 4.0 in an amount corresponding to the expected consumption. The solution obtained is applied on the mineral building material within 3 to 30 minutes after the reactants are mixed. Suitable hydrolysis apparatus is also disclosed.
