| 摘要 |
An aqueous preparation for impregnating or hydrophobizing mineral building materials containing an emulsion of polyfunctional carbosilane and/or siloxane, an organo(poly)siloxane, a water dispersible or emulsifyable organic polymer, and water dispersible or dispersed inorganic nanoparticles gives the materials adequate chemical stability easy-cleaning properties. The aqueous preparation contains: (I) an emulsion of polyfunctional carbosilanes and/or siloxanes (A); (II) an emulsion of at least one organo(poly)siloxane (B); (III) at least one water dispersible or emulsifyable organic polymer (C); water-dispersed or dispersible inorganic nanoparticles (D); and/or additional additives (E). Independent claims are included for: (1) preparation of the aqueous preparation with stirring together of components (I) to (V); (2) treatment of mineral building materials as above, and drying of these at a temperature less than 150 degrees C. |
