Abstract
The present invention relates to novel aqueous preparations for the treatment of mineral building materials containing (I) an aqueous emulsion of at least one polyfunctional carbosilane and/or carbosiloxane (A) and/or the (partial) condensation product thereof, (II) an emulsion of at least one organo(poly)siloxane (B), (III) at least one organic polymer (C) dispersible or emulsified in water, (IV) inorganic nanoparticles (D) dispersed or dispersible in water, and (V) optionally other additives (E).
Claims17
An aqueous preparation comprising
- (I) an emulsion of a polyfunctional carbosilane and/or carbosiloxane (A), that contains at least two units of the formula (1)
- —(CH2)mSiR1nX3−n (1)
- wherein
- m is from 1 to 6,
- n is from 0 to 2,
- R1 is an unsubstituted C1-C18 hydrocarbon or a hydrocarbon that contains at least one of O, N, S, or P, each R1 within the molecule being identical or different, and
- X is a radical selected from the group consisting of OH, C1-C4 alkoxy, C6-C20 aryloxy, C1-C6 acyloxy, and hydrogen,
- (II) an emulsion of at least one organo(poly)siloxane (B),
