Abstract
Description
Wärmedämmputz Die Erfindung betrifft einen Wärmedämmputz als Beschichtung fïr die Außenseite von Gebäuden, der unter anderem Zement als Bindemittel und einen Anteil von Polystyrol (Styropor) enthält. Thermal insulation plaster The invention relates to a thermal insulation plaster as a coating for the outside of buildings, which, among other things, uses cement as a binding agent and a Contains a proportion of polystyrene (Styrofoam).
Wärmedämmputz und Isolierputz mit einem gewichtsmäßig kleinen, aber volumenmäßiC großen Anteil an expandierten Polystyrol-Partikeln imr einem diese Partikel zusammenhaltenden Findemittel ist bereits bekannt. Je geringer die Festmörtelrohdichte, also die Dichte des Wärmedämmputzes im abgebundenen trockenen Zustand ist, um so besser ist die Wärmedämmwirkung eines solchen Verputzmaterials. Entscheidenden Anteil an der Festmörtelrohdichte hat der im Wärmedämmputz verwendete Zement als Bindemittel, der far eine ausreichende Festigkeit des Wärmedämmputzes verantwortlich ist. Der Bindemittelanteil im Wärmedämmputz kann daher nicht ohne weiteres verringert werden.Thermal insulation plaster and insulating plaster with a weight-wise small, but In terms of volume, there is a large proportion of expanded polystyrene particles in one of these Particle-holding means is already known. The lower the solid mortar density, So the density of the thermal insulation plaster in the hardened dry state is so the thermal insulation effect of such a plastering material is better. Decisive part the cement used in the thermal insulation plaster has as a binding agent at the solid mortar density, which is responsible for a sufficient strength of the thermal insulation plaster. Of the The proportion of binding agent in the thermal insulation plaster cannot therefore be reduced without further ado.
Der Erfindung liegt die Aufgabe zugrunde, in einem Zement als Bindemittel aufweisenden Wärmedämmputz den Gewichtsanteil des Zementes ohne Beeinträchtigung der Festigkeit des Wärmedämuiputzes zur Verminderung der Festmörtelrohdichte zu verringern.The invention is based on the object in a cement as a binder exhibiting thermal insulation plaster the weight proportion of the cement without impairment the strength of the thermal insulation plaster to reduce the solid mortar density to decrease.
Die ges-tellte Aufgabe wird bei einem Wärmedämmputz der eingangs genannten Art erfindungsgemäß dadurch gelöst, daß er einen Anteil von hydrolysierter Kieselsäure aufweist. Dieser Anteil kann gewichtsmäßig vorteilhafterweise ca. 3 - 5 <I des Gewichtsanteiles des Zementes betragen.In the case of a thermal insulation plaster, the task given is the one mentioned at the beginning Type solved according to the invention in that it contains a proportion of hydrolyzed silica having. In terms of weight, this proportion can advantageously be approx. 3 - 5 <I des Proportion by weight of the cement.
Es hat sich gezeigt, daß synthetisch gewonnene, hochdisperse reine Kieselsäure, beispielsweise durch vlammenhydrolyse aus Siliciumtetrachlorid gewonnen, ein ausgezeichnetes, in Verbindung mit Portlandzement problemlos anwendbares Binde mittel oder Bindeverstärkungsmittel ist, mit welchem eine wesentliche Erhöhung der Bindekraft und Festigkeit von Portlandzement erreichbar ist. Diese hydrolysierte Kieselsäure erlaubt eine Verminderung des Zementanteiles im Wärmedamm putz, wobei durch eine Gewichtseinheit hydrolysierte Kteselsäure etwa zehn Gewichtsanteile von Portlandzement ersetzt werden können. Durch die mögliche Verminderung des Zementanteiles im Wärmedämmputz läßt sich ohne eine Verminderung der Festigkeitswerte und anderer wichtiger physikalischer igenschaften des Wärmedämmputzes eine Verbesserung, das heißt Verminderung der Festmörtelrohdichte von ca. 25 % erzielen.It has been shown that synthetically obtained, highly dispersed pure Silica, e.g. obtained from silicon tetrachloride by flame hydrolysis, an excellent bandage that is easy to use in conjunction with Portland cement agent or binding reinforcing agent, with which a substantial increase in the The cohesiveness and strength of Portland cement is achievable. This hydrolyzed Silicic acid allows a reduction of the cement content in the thermal insulation plaster, whereby by one weight unit hydrolyzed ktesic acid about ten parts by weight of Portland cement can be substituted. Due to the possible reduction in the proportion of cement in thermal insulation plaster can be used without reducing the strength values and others important physical properties of the thermal insulation plaster an improvement that means to achieve a reduction of the solid mortar density of approx. 25%.
Die genannten Werte wurden bei einem Wärmedämmputz als Ausfïhrungsbeispiel erzielt, bei welchem eine Menge von annähernd 200 kg gewichtsmäßig aus folgenden Bestandteilen zusammengesetzt ist: Portlandzement 164,0 kg ca. 82 Meth. Cellulose 1,5 kg ca. 0,75 % Zinkstearat 1,5 kg ca. 0,75 % Styroporfasern 1,2 kg ca. 0,5 % Styroporgranulat 15,6 kg ca. 8 Styropor vorgeschäumt 9,6 kg ca. 5 hydrolysierte Kieselsäure 6,0 kg ca. 3 199,4 kg 100 gegenaber einem Wärmedämmputz ohne hydrolysierte Kieselsäure mit folgender Zusammensetzung: Portlandzement 220,0 kg Meth. Cellulose 1,5 kg Zinkstearat 1,5 kg Styroporfasern 1,2 kg Styroporgranulat 15,6 kg Styropor vorgeschäumt 9,6 kg hydrolysierte Kieselsäure 6,0 kg 249,4 kg.The values mentioned were for a thermal insulation plaster as an exemplary embodiment achieved, in which an amount of approximately 200 kg by weight of the following Components is composed: Portland cement 164.0 kg approx. 82 meth. Cellulose 1.5 kg approx. 0.75% zinc stearate 1.5 kg approx. 0.75% styrofoam fibers 1.2 kg approx. 0.5% Styrofoam granulate 15.6 kg approx. 8 Styrofoam pre-expanded 9.6 kg approx. 5 hydrolyzed Silicic acid 6.0 kg approx. 3,199.4 kg 100 against a thermal insulation plaster without hydrolyzed Silicic acid with the following composition: Portland cement 220.0 kg meth. Cellulose 1.5 kg zinc stearate 1.5 kg styrofoam fibers 1.2 kg styrofoam granules 15.6 kg styrofoam pre-expanded 9.6 kg hydrolyzed silica 6.0 kg 249.4 kg.
