摘要： Des émulsions aqueuses de (A) organopolysiloxane dépourvu d'azote de base et de (B) alkyltrialcoxysilane contiennent (C) un émulsifiant et (D) de l'eau. L'organopolysiloxane (A) a la formule RaSi(OR1)bO4-ab/2, dans laquelle R désigne des résidus hydrocarbures C1-C18 monovalents identiques ou différents, substitués le cas échéant et liés par SiC; R1 désigne des résidus hydrocarbures C1-C6 monovalents identiques ou différents; a vaut 0, 1, 2 ou 3, en moyenne 0,75 à 1,5 et b vaut 1, 2, 3, en moyenne 0,2 à 2,0, l'organopolysiloxane ayant un poids moléculaire égal à au moins 600 g/mol. L'invention concerne également un procédé de production de ces émulsions et leur utilisation comme imprégnation hydrofuge d'éléments fibreux de construction liés avec du ciment.

摘要： The invention concerns a dispersion powder composition which is redispersible in water and is made from water-insoluble homopolymers or copolymers of preferably ethylenically unsaturated monomers and one or more organosilicon compounds plus, optionally, other additives such as protective colloids and anti-blocking agents. The composition is obtained by: a) polymerizing one or more monomers in the presence of 0.1 to 30% by wt., relative to the total weight of the monomers, of one or more silicon compounds which are dispersible in water and which have a boiling point at normal pressure of > 160 °C, selected from the group comprising the silanes, polysilanes, oligosiloxanes, polysiloxanes, carbosilanes, polycarbosilanes, carbosiloxanes, polycarbosiloxanes and polysilylenedisiloxanes and: b) spray-drying the product thus obtained, either before or after addition of the additives mentioned.

摘要： The invention concerns aqueous emulsions of (A) organopolysiloxane free from basic nitrogen and (B) alkyltrialkoxysilane which contain (C) an emulsifier and (D) water. Organopolysiloxane (A) has formula RaSi(OR1)bO4-a-b/2, wherein R has identical or different, monovalent, optionally substituted C1-C18 hydrocarbon residues bonded by SiC, R1 has identical or different, monovalent, optionally substituted C¿1?-C6 hydrocarbon residues, a is equal to 0, 1, 2 or 3, on average 0.75 to 1.5, and b is equal to 1, 2 or 3, on average 0.2 to 2.0, and has a molecular weight of at least 600 g/mol. Also disclosed are a method for preparing said emulsions and their use for water-repellent impregnation of cement-bonded fibrous building components.
