Abstract
Description
Selbstausgleichende Estrichmas s e Die Erfindung betrifft selbstausgleichende Massen zum Glätten der Oberflächen von Fußböden, insbesondere solchen aus Beton oder dergleichen, so daß sich Kacheln, Platten, Parkettstäbe oder dergleichen auf dem Estrich befestigen lassen. Massen für diesen Zweck sind an sich bekannt und enthalten meist Sand sowie Zement (zum Aushärten) sowie Kasein (für das selbsttätige Ausgleichen und Glätten). Die Verwendung von Kasein oder anderen Proteinen ist insofern nachteilig als durch diese ein Befall mit Bakterien oder anderen Mikroorganismen begünstigt wird, insbesondere unter feuchten Umweltbedingungen. Self-leveling screed compound The invention relates to self-leveling Compounds for smoothing the surfaces of floors, especially those made of concrete or the like, so that tiles, panels, parquet strips or the like are on can be attached to the screed. Masses for this purpose are known per se and mostly contain sand as well as cement (for hardening) and casein (for the self-acting Leveling and smoothing). The use of casein or other proteins is insofar disadvantageous than this an infestation with bacteria or other microorganisms is favored, especially in humid environmental conditions.
Es wurde nunmehr überraschend gefunden, daß sich das Kasein durch bestimmte andere Verbindungen ersetzen läßt, so daß man proteinfreie und damit biologisch inerte selbstausgleichende Massen erhält.It has now been found, surprisingly, that the casein works through can replace certain other compounds, so that one is protein-free and thus biological inert self-balancing masses obtained.
Gegenstand der Erfindung ist demgemäß eine selbstausgleichende Estrichmasse mit Gehalt an Sand und Zement, welche durch einen Gehalt an Lignosulfonat und einem Metallsalz einer Schwefelsauerstoffsäure, ausgenommen Sulfat, gekennzeichnet ist. The invention accordingly relates to a self-leveling screed compound with content of sand and cement, which by a content of lignosulfonate and a Metal salt of a sulfuric acid, with the exception of sulphate, is labeled.
Bevorzugte Metallsalze sind Sulfite, Bisulfite und meta-Bisulfite; ferner können Thiosulfite, Thionate und Thiosulfate Verwendung finden. Die Kationen der Salze sind vorzugsweise Natrium oder Calcium. Vorzugsweise beträgt der Gehalt an Sulfit oder einem anderen Salz einer Schwefelsauerstoffsäure etwa 0, 2 bis 5 Gew. %. Preferred metal salts are sulfites, bisulfites and meta-bisulfites; furthermore, thiosulfites, thionates and thiosulfates can be used. The cations of the salts are preferably sodium or calcium. The content is preferably on sulfite or another salt of a sulfuric acid about 0.2 to 5 Weight%.
Bei dem Lignosulfonat handelt es sich vorzugsweise um eine Natrium- oder Calciumverbindung, welche günstigerweise in Form einer Sulfitlauge eingesetzt werden kann. Besonders geeignet sind mit Hilfe von Zucker reduzierte Sulfitlaugen. Der Gehalt an Lignosulfonat beträgt vorzugsweise etwa 0, 05 bis 3 Gew. %. The lignosulfonate is preferably a sodium or calcium compound, which is advantageously used in the form of a sulphite liquor can be. Sulphite liquors reduced with the help of sugar are particularly suitable. The content of lignosulfonate is preferably about 0.05 to 3% by weight.
Vorzugsweise enthält die Masse ferner ein pulverförmiges Vinylpolymeres, beispielsweise Polyvinylacetat oder ein Copolymeres desselben, um die Bindefähigkeit und die Nachgiebigkeit der Masse zu erhöhen. Der Gehalt an Polymerem kann bei etwa 1 bis 10 Gew. The composition preferably also contains a pulverulent vinyl polymer, for example polyvinyl acetate or a copolymer of the same, in order to improve the bondability and to increase the compliance of the mass. The content of polymer can be about 1 to 10 wt.
liegen. lie.
Der Sand und der Zement bzw. die Zemente werden so ausgewählt, daß man eine Masse mit verhältnismäßig kurzer Abbindezeit erhält; ein Gemisch aus Portlandzement und Zement mit hohem Aluminiumoxidgehalt ist bevorzugt. Weiterhin können andere inerte Füllstoffe zugesetzt wer den, beispielsweise Aluminiumoxid/Chr omitmehl. Der Sandgehalt kann etwa 30 bis 70 Gew. % und der Zementgehalt etwa 25 bis 65 Gew. % betragen, wobei der Zementanteil vorzugsweise mindestens 20 Gewichtsteile Portlandzement und im übrigen Zement mit Ihohem Aluminiumoxidgehalt enthält.The sand and the cement or cements are selected so that a mass with a relatively short setting time is obtained; a mixture of portland cement and high alumina cement is preferred. Furthermore, others can inert fillers added to who, for example aluminum oxide / chromite flour. The sand content can be about 30 to 70% by weight and the cement content about 25 to 65% by weight. %, the proportion of cement preferably being at least 20 parts by weight of Portland cement and otherwise contains cement with a high aluminum oxide content.
Schließlich kann die Masse noch schaumunterdrückende Mittel sowie Bakterizide enthalten.Finally, the mass can still contain foam suppressants as well Contains bactericides.
Vor der Verwendung wird die Masse mit Wasser zu einer Paste angerührt, welche auf den Untergrund aufgebracht wird, so daß ein Estrichüberzug von bis zu 3 mm Stärke erhalten wird. Falls eine noch größere Stärke erforderlich ist, wird der Sandgehalt entsprechend erhöht. Der Boden kann gegebenenfalls mit einem Primer behandelt werden, beispielsweise mit einem Latex auf Polyvinylacetatbasis, bevor die Masse aufgebracht wird.Before use, the mass is mixed with water to form a paste, which is applied to the substrate, so that a screed coating of up to 3 mm thickness is obtained. If even greater strength is required, then the sand content increases accordingly. The floor can optionally be primed treated, for example with a latex based on polyvinyl acetate before the mass is applied.
Zur Erläuterung der Erfindung soll das nachfolgende Beispiel dienen, in welchem die Zusammensetzung in Gewichtsteilen angegeben ist: Beispiel Sand 47, 8 Zementgemis ch 47, 85 pulverförmiges Polyvinylacetat 2,4 Natriumsulfit 0, 9 Lignosulfonat 0, 9 Schaumunterdrücker (BEVALOID der Firma 0, 1 Hodgson & Sons Ltd., Yorks, England) Bakterizid 0, 05.The following example is intended to explain the invention, in which the composition is given in parts by weight: example Sand 47, 8 cement mix 47, 85 powdered polyvinyl acetate 2,4 sodium sulfite 0, 9 lignosulfonate 0, 9 foam suppressor (BEVALOID from 0, 1 Hodgson & Sons Ltd., Yorks, England) bactericide 0.05.
Diese Zusammensetzung wurde im Verhältnis 5:1 mit Wasser vermischt, so daß eine Paste erhalten wurde, welche mit Hilfe einer Kelle auf einen Betonuntergrund aufgebracht wurde, so daß ein blasenfreier, sich selbst glättender Estrich erhalten wurde, welcher nach 4 Stunden betreten werden konnte.This composition was mixed with water in a ratio of 5: 1, so that a paste was obtained, which with the help of a trowel on a concrete substrate was applied so that a bubble-free, self-smoothing screed obtained which could be entered after 4 hours.
Nach 24 bis 48 Stunden konnte ein Fußbodenbelag in Form von Parkettstäben, Auslegeteppich, Kunststoffplatten oder Fliesen auf dem Estrich verlegt werden.After 24 to 48 hours, a floor covering in the form of parquet strips, Carpet, plastic sheets or tiles are laid on the screed.
Weitere trockene Grundmassen wurden unter Verwendung von Calciumsulfit und Natriumthiosulfat hergestellt, wobei ähnliche Endergebnisse erzielt wurden.More dry bases were made using calcium sulfite and sodium thiosulfate with similar end results.
