Verfahren zum Schützen von GebäudeteilenMethod for protecting parts of buildings
Die Erfindung betrifft das Schützen von Gebäuden und Gebäudeteilen aus Ziegelsteinen, Beton, Natursteinen oder ähnlichen Materialien durch chemische Mittel gegen Feuchtigkeit.The invention relates to the protection of buildings and parts of buildings from bricks, concrete, natural stone or similar materials by chemical means against moisture.
Wasser kann durch die Ziegel oder den Mörtel einer Wand durch Kapillarkräfte hindurchströmen und zur Verhinderung dieser Erscheinung ist bereits vorgeschlagen worden, in der Wand eine wasserdichte Barriere aus einem gelierten Alkalisilikat, meist . Natriumsilikat, zu bilden. Die Barriere wird erzeugt, indem man eine wässrige Silikatlösung, welche gegebenenfalls ein Silikonat enthält, in die Wand injiziert und gelieren lässt. Ein derartiges Verfahren ist in der GB-PS 1 177 662 beschrieben, aus "welcherWater can get through the bricks or mortar of a wall Capillary forces flow through and to prevent this phenomenon has already been proposed, in the wall a waterproof barrier made of a gelled alkali silicate, mostly. Sodium silicate, to form. The barrier is created by an aqueous silicate solution, which may contain a siliconate, is injected into the wall and allowed to gel. Such a thing The method is described in GB-PS 1 177 662, from "which

weiterhin der Vorschlag bekannt ist/ der Lösung zur Verminderung der Gelierungsdauer Essigsäure zuzufügen. Die vorliegende Erfindung beruht darauf, dass überraschend gefunden wurde, dass sich das vorbekannte Verfahren verbessern lässt, wenn man bestimmte Ester, vorzugsweise Essigsäureester, des Glycerins anstelle der Essigsäure verwendet.the proposal is still known / the solution to reduce it add acetic acid to the gelation time. The present invention is based on the fact that, surprisingly, it has been found that the previously known method can be improved if certain Esters, preferably acetic acid esters, of glycerol are used instead of acetic acid.
Gegenstand der Erfindung ist demgemäss ein Verfahren zum Schutz von Gebäudeteilen gegen Feuchtigkeit durch Einbringen einer wässrigen Alkalisilikatlösung, welches dadurch gekennzeichnet ist, dass man zunächst das Silikat mit einem hydrolysierbaren Ester umsetzt, um das Silikat zur Bildung einer wasserfesten Barriere zu gelieren.The invention accordingly relates to a method of protection of building parts against moisture by introducing an aqueous alkali silicate solution, which is characterized by that the silicate is first reacted with a hydrolyzable ester in order to form a water-resistant barrier with the silicate to gel.
Vorzugsweise weist der hydrolysierbare Ester in dem Säurerest 1 bis 4 Kohlenstoffatome auf, wobei es sich bei dem Säurerest vorteilhafterweise um den Rest einer Carbonsäure handelt. -Besonders bevorzugt ist die Säure Essigsäure, doch lassen sich auch Ameisensäure und Buttersäure verwenden.Preferably the hydrolyzable ester has in the acid residue 1 to 4 carbon atoms, the acid residue advantageously being the residue of a carboxylic acid. -Particularly Acetic acid is preferred, but formic acid and butyric acid can also be used.
Untersuchungen haben gezeigt, dass ein derartiger Ester durch das Alkalisilikat langsam hydrolysiert wird, wobei kontrollierbare Gelierungszeiten erzielt werden, weil die Geschwindigkeit der Hydrolyse der verwendeten Estermenge proportional ist. Darüberhinaus wird nicht plötzlich eine grössere Wärmemenge frei, wennStudies have shown that such an ester is slowly hydrolyzed by the alkali silicate, being controllable Gel times can be achieved because the rate of hydrolysis is proportional to the amount of ester used. Furthermore a large amount of heat is not suddenly released when
309823/0772309823/0772
die Silikatlösung mit dem Ester umgesetzt wird, so dass während der gesamten Umsetzung eine im wesentlichen konstante Temperatur herrscht, was zu reproduzierbaren Gelierungszeiten führt. Da das Silikatgel nur schwach alkalisch reagiert, wirkt es nicht korrodierend und hat keinen nachteiligen Einfluss auf das Mauerwerk und den Mörtel, was für die Verwendung als Feuchtigkeitsschutzmittel wesentlich ist.the silicate solution is reacted with the ester, so that during an essentially constant temperature prevails throughout the reaction, which leads to reproducible gel times. Since that Silicate gel only reacts in a weakly alkaline manner, it is non-corrosive and has no negative impact on the masonry and the mortar, which is essential for use as a moisture protectant.
Der verwendete Ester ist vorzugsweise ein Monoacetat, Diacetat oder Triacetat. Bevorzugte Ester sind u.a. Äthylacetat, Glycerinmonoacetat, Butylglykolacetat, 1,3-Butylenglykolacetat, Äthylenglykolmonoacetat, 1,4-Butylenacetat, Hexylacetat, Nonylacetat, 2-Äthylacetat, Äthylenglykolmonoäthylätheracetat, Äthylenglykoldiacetat, Glycerindiacetat (auch als "Diacetin" bezeichnet), Diäthylenglykoldiacetat, Triäthylenglykoldiacetat, Propylenglykoldiacetat, sowie Glycerintriacetat (auch als "Triacetin" bezeichnet).The ester used is preferably a monoacetate, diacetate or triacetate. Preferred esters include ethyl acetate, glycerol monoacetate, butyl glycol acetate, 1,3-butylene glycol acetate, ethylene glycol monoacetate, 1,4-butylene acetate, hexyl acetate, nonylacetate, 2-ethyl acetate, ethylene glycol monoethyl ether acetate, ethylene glycol diacetate, also referred to as "diethyl diacetate", glycerol diacetate, ethylene glycol diacetate (tri-glycol diacetate) . Propylene glycol diacetate, as well as glycerol triacetate (also referred to as "triacetin").
Es ist am günstigsten, wenn der Ester mit Wasser mischbar ist, wenngleich sich einige der oben aufgezählten Ester, z. B. Äthylacetat, mit Wasser in der erforderlichen Weise nur nach Zusatz eines Emulgiermittels mischen lassen. Günstigerweise findet ein Gemisch aus Estern niedriger und hoher Löslichkeit Verwendung, vorzugs*- weise ein Gemisch mit Gehalt an Diacetin (technische Qualität) und Triacetin in einem Gewichtsverhältnis von 85 bis 60:15 bis mit einer Verseifungszahl im Bereich von 535 bis 603 mg KOH/g.It is best if the ester is miscible with water, although some of the esters listed above, e.g. B. ethyl acetate, mix with water in the required manner only after adding an emulsifying agent. Favorably finds a mixture from esters of low and high solubility use, preferred * - wise a mixture containing diacetin (technical grade) and triacetin in a weight ratio of 85 to 60:15 with a saponification number in the range from 535 to 603 mg KOH / g.
