PROCESS FOR THE TREATMENT OF MINERAL BUILDING MATERIALS

摘要

The invention relates to a process for the impregnating and priming treatment of mineral building materials of synthetic or natural origin using aqueous suspensions or solutions which are characterised in that they contain at least one silicon-containing ion exchanger of the general formula: ¢(YO)3Si(CH2)x!nEX (I) or an oligomer of this compound, wherein x signifies 1 to 12, n signifies 1 to 3, depending on E Y signifies H, Na, K, Mg, Ca, Ba E signifies a cation-exchanging or anion exchanging group, and x signifies H+or an alkali cation or alkaline earth cation or OH- or an anion, in a quantity of from 0.1 to 70% by weight, particularly from 10 to 30% by weight, referred to the total quantity of the solution or suspension, with the treatment being carried out in a single stage or in multiple stages, optionally combined with a treatment with aqueous or organic emulsions or solutions containing hydrolysable silanes and/or siloxanes.
