Process for the treatment of mineral building materials

摘要

A process for the impregnating and priming treatment of mineral building materials of synthetic or natural origin using aqueous suspensions or solutions which contain at least one silicon-containing ion exchanger of the formula[(YO)3Si(CH2)x]nEX(I)or an oligomer of this compound, wherein x signifies an integer of 1 to 12, n signifies an integer of 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, based on 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 hydrolyzable silanes and/or siloxanes.
