Abstract

The mortars consist of dry mixts. of group limestone and expanded perlite, both under 0.5 mm particle size, with a hydraulic binder and opt. with addn. of a cellulose deriv., polymer, wetting agent, hydrophobic cpd. or setting time regulator. Pref. compsns. contain methyl cellulose or hydroxypropyl methyl cellulose, PVAc and/or melamine resin, triethanolamine salt of lauryl sulphate or sodium lauryl ether sulphate, a sulphonium salt or metal soap, and K2O3 or similar setting time regulator. The mortars give an extremely smooth surface which can be painted or papered without further treatment. Excessive shrinkage and formation of a network of cracks is prevented. The polymers improved adhesion to the plaster base and the hydrophobic cpds. allow exterior use without a protective cover layer.

Description

Feinstmörtel für Innen- und Außenputz Bisher sind Feinstmörtel nur auf Gissbasis bekannt. Fine mortar for interior and exterior plaster So far, fine mortars are only known on a Giss basis.

Diese sind als Außenputz nicht verwendbar, weil sie nicht wasser- und damit nicht wetterbeständig sind.These cannot be used as external plaster because they are not water- and are therefore not weatherproof.

Die nachstehende Erfindung bezieht slch nun auf einen Peinstmörtel, der auf der Basis hydraulischer Bindemittel erzeugt wird. Br stellt ein Gemisch aus hydraulischen Bindemitteln mit verschiedenen Zuschlägen und Zusätzen dar, wobei die Körnung unter 0,5 mm liegen muß. Als Folge dieser Zusammensetzung sowie der innigen Mischung der Komponenten bereits im Tjerk wird bei der Verarbeitung auf der Baustelle eine außerordentlich glatte Putzoberfläche erzielt. Ohne weitere Vorbehandlung können Anstrich oder Tapezierung aufgebracht erden.The following invention now relates to a Peinstmörtel, which is produced on the basis of hydraulic binders. Br represents a mixture made of hydraulic binders with various aggregates and additives, whereby the grain size must be less than 0.5 mm. As a result of this composition as well as the intimate mixture of the components already in the Tjerk is based on during processing the construction site achieves an extremely smooth plaster surface. Without further pre-treatment painting or wallpapering can be applied.

Der erfindungsgemäße Feinstmörtel für Innen- und Außenputz ist dadurch gekennzeichnet, daß er aus einer trockenen Mischung aus gemahlenem Kalkstein und geblähtem Perlit, beide mit einer Körnung unter o,5 mm, mit einem liydraulischen Bindemittel und gegebenenfalls mit einem Zusatz eines Zellulosederivates, eines Polymerisates, eines Netzmittels, eines hydrophoben lAL4tels oder eines Abbindezeitreglers, einzeln oder im Gemisch miteinander besteht.The fine mortar according to the invention for interior and exterior plaster is thereby characterized in that it is made from a dry mixture of ground limestone and expanded perlite, both with a grain size below 0.5 mm, with a liydraulic binder and optionally with an addition of a cellulose derivative, a polymer, a wetting agent, a hydrophobic IAL4tels or a setting time regulator, individually or in a mixture with one another.

Der Peinstmörtel kann, ohne daß hierdurch seine Eigenschaften verändert würden, mit Putzmaschinen verarbeitet werden. Die Mörtelschicht braucht nur so stark aufgebracht zu werden, daß sie den Putzgrund voll abdeckt. Die Oberflächen können von Hand oder maschinell geglättet werden.The Peinstmörtel can be used without changing its properties would be processed with plastering machines. The mortar layer just needs as strong to be applied that it fully covers the plaster base. The surfaces can can be smoothed by hand or by machine.

Die bei einer dünnen Putzschicht uberstarke ßchwindneigung und das durch sie bewirkte Auftreten von Netzrissen werden durch die Zugabe von entsprechenden Zusätzen im Verein mit speziellen Zuschlägen völlig ausgeschaltet. Die Kunststoffzusätze wirken in dieselbe Richtung und verbessern überdies die Haftung am Putzgrund so stark, daß die Gefahr von Haftschäden beseitigt ist. Als Kunststoffe können Polyvinylacetat und/oder ein Melaminharz verwendet werden. Durch Beigabe von hydropnoben Zusätzen, wie z.B.The excessive tendency to wind with a thin layer of plaster and that caused by them occurrence of network cracks are by the addition of appropriate Completely switched off additives in association with special supplements. The plastic additives act in the same direction and also improve adhesion to the plaster base strong that the risk of liability damage is eliminated. Polyvinyl acetate can be used as plastics and / or a melamine resin can be used. By adding hydropnobic additives, such as.

ein Sulfoniumsalz oder Metallseifen, kann der Feinstmörtel besonders gut als Außenputz Verwendung finden, d.h. auch ohne schützende Deckschicht an den atmosphärischen Einflüssen Widerstand leisten.A sulfonium salt or metal soaps, the fine mortar can especially Can be used well as external plaster, i.e. even without a protective top layer on the resist atmospheric influences.

Durch Zugabe von entsprechenden Abbindezeitreglern, wie z.B. Kaliumkarbonat, wird das Erstarren des verarbeiteten Putzes so beeinflusst, daß ein rascher Arbeitsfortschritt erzielt wird. Der Peinstmörtel wird im Werk fabrikmäßig hergestellt und in Papier- oder Plastiksäcken zum Versand gebracht werden. Auf der Baustelle wird er mit Wasser gemischt und kann daraufhin von Hand oder maschinell verarbeitet werden.By adding appropriate setting time regulators, such as potassium carbonate, the solidification of the processed plaster is influenced in such a way that rapid work progress is achieved. The Peinstmörtel is manufactured in the factory and in paper or plastic bags are brought for shipping. At the construction site he is using water mixed and can then be processed by hand or by machine.

Der Zusatz an Zellulosederivaten, wie Methylzellulose, Hydroxypropyl-Methylzellulose u.dgl. verbessert die Wasserretention des Mörtels und somit die Verarbeitbarkeit desselben. Der erfindungsgemäße Feinstmörtel kann in zwei Gruppen geteilt werden und zwar: a) für Innenputz und b) für Außenputz, indem ihm hydrophobe Zusätze beigegeben werden.The addition of cellulose derivatives such as methyl cellulose, hydroxypropyl methyl cellulose and the like improve the water retention of the mortar and thus the workability same. The fine mortar according to the invention can be divided into two groups namely: a) for interior plaster and b) for exterior plaster by adding hydrophobic additives will.
