Description
Die Verwendung einer wäßrigen Dispersion zum homogenen Verbinden von Baustoffen Nach der deutschen Auslegeschrift 1 213 779 ist es bekannt, zum homogenen Verbinden von alten und frischen hydraulisch abbindenden Baustoffen mit Hilfe eines organischen Bindemittels, das eine selbständige Zwischenschicht bildet, als Bindemittel eine wäßrige Dispersion von Polyvinylpropionat zu verwenden.The use of an aqueous dispersion for the homogeneous bonding of Building materials According to the German Auslegeschrift 1 213 779, it is known to be homogeneous Joining of old and fresh hydraulically setting building materials with the help of a organic binder, which forms an independent intermediate layer, as a binder to use an aqueous dispersion of polyvinyl propionate.
Diese wäßrige Dispersion kann 5 bis 50% Polyvinylpropionat und gegebenenfalls Weichmacher und/oder Netzmittel enthalten. Die wäßrige Dispersion von Polyvinylpropionat kann ferner ein Füllmittel, vorzugsweise Sand und/oder Zement, enthalten. Bei der Verwendung dieses Mittels kann man die Dispersion auf einen feuchten Untergrund auftragen und vor dem Trocknen die neue Schicht aufbringen.This aqueous dispersion can contain 5 to 50% polyvinyl propionate and optionally Contain plasticizers and / or wetting agents. The aqueous dispersion of polyvinyl propionate can also contain a filler, preferably sand and / or cement. In the Using this agent you can apply the dispersion to a damp surface apply and apply the new layer before drying.
Nach der schweizerischen Patentschrift 322 566 ist es ferner bekannt, zur Verbindung von alten und neuen Beton- oder Zementmörtelschichten eine wäßrige Kunststoffdispersion zu verwenden, die vorzugsweise Polyvinylacetat oder ein Polyvinylacetat enthaltendes Mischpolymerisat enthält. According to Swiss patent specification 322 566, it is also known an aqueous one for connecting old and new concrete or cement mortar layers Use plastic dispersion, which is preferably polyvinyl acetate or a polyvinyl acetate containing copolymer contains.
Diesen bekannten Verfahren ließ sich nicht entnehmen, ob es gelingt, mit Hilfe von wäßrigen Kunststoffdispersionen auch solche Schichten zu verbinden, bei welchen eine oder beide aus Gips bestehen. Die Eigenschaften von Gips, insbesondere seine Ausdehnung beim Abbinden, unterscheiden sich so weit von den Eigenschaften hydraulisch abbindender Baustoffe, daß ein Schluß von diesen auf Gips nicht möglich ist. It was not possible to infer from these known methods whether it would be possible to to connect such layers with the help of aqueous plastic dispersions, in which one or both are made of plaster of paris. The properties of plaster of paris, in particular its expansion when setting, differ so far from the properties hydraulically setting building materials that a conclusion from these to gypsum is not possible is.
Die Erfindung betrifft die Verwendung von an sich bekannten wäßrigen, gegebenenfalls anorganische Füllstoffe und/oder Weichmacher und/oder Netzmittel enthaltenden Dispersionen von Polyvinylpropionat oder eines Mischpolymerisats von Vinylpropionat mit Vinylacetat oder eines Mischpolymerisats von Vinylpropionat mit Vinylchlorid oder eines Mischpolymerisats von Vinylpropionat mit Vinylacetat und mit Vinylchlorid oder eines Gemisches von zwei oder mehreren dieser Polymerisate zum homogenen Verbinden von Baustoffen, die ganz oder teilweise aus Gips bestehen. The invention relates to the use of known aqueous, optionally inorganic fillers and / or plasticizers and / or wetting agents containing dispersions of polyvinyl propionate or a copolymer of Vinyl propionate with vinyl acetate or a copolymer of vinyl propionate with Vinyl chloride or a copolymer of vinyl propionate with vinyl acetate and with vinyl chloride or a mixture of two or more of these polymers for the homogeneous connection of building materials that consist entirely or partially of plaster of paris.
Die hierbei verwendeten wäßrigen Dispersionen können außer dem organischen Bindemittel noch anorganische Füllstoffe enthalten, wie z. B. Sand und gegebenenfalls Zement. Besonders gut bewährt haben sich solche Dispersionen, die als anorganischen Füllstoff Gips, gegebenenfalls zusammen mit Sand, enthalten. The aqueous dispersions used here can, in addition to the organic Binders still contain inorganic fillers, such as. B. sand and optionally Cement. Those dispersions which have proven to be particularly effective are those which are considered to be inorganic Contains plaster of paris, optionally together with sand.
Mittels des erfindungsgemäßen Verfahrens gelingt es, einen Gipsputz auch auf schwierigem Putzgrund aufzubringen, wobei eine einwandfreie Haftung des Putzes erzielt wird. Das Verfahren kommt besonders in Betracht zum Verputzen von glattgeschalten Betonfiächen, Betonflächen mit Schalölresten, Betonflächen mit Schalpasteresten, Flächen mit Anstrichen von Dispersionsfarben, Flächen mit Bitumenanstrichen, Leichtbauplatten, Platten aus Schaumstoffen, Hartbrandziegeln, Natursteinflächen. In allen diesen Fällen ist ein Aufrauhen oder eine sonstige Vorbehandlung außer gegebenenfalls einer Reinigung und einem Anfeuchten des Untergrundes nicht erforderlich. By means of the method according to the invention it is possible to obtain a gypsum plaster can also be applied to a difficult plaster base, with perfect adhesion of the Plaster is achieved. The procedure is special considering for plastering smooth concrete surfaces, concrete surfaces with formwork oil residues, concrete surfaces with formwork paste residues, Areas with coating of emulsion paints, areas with bitumen coatings, lightweight panels, Foam panels, hard-fire bricks, natural stone surfaces. In all of these Cases is a roughening or other pretreatment apart from, if necessary, one Cleaning and moistening of the substrate is not necessary.
Es wurde ferner gefunden, daß in manchen Fällen eine noch bessere Haftung des aufzubringenden Gipsputzes erreicht wird, wenn man ihm geringe Mengen der erfindungsgemäßen wäßrigen Dispersion, vorzugsweise 1 bis 20/o, bezogen auf das Gewicht des trockenen Gipses, zumischt. It has also been found that in some cases an even better Adhesion of the applied gypsum plaster is achieved if you give it small amounts the aqueous dispersion according to the invention, preferably 1 to 20 / o, based on the weight of the dry plaster of paris.
Beispiel In allen Fällen wurde als Untergrund Beton verwendet, der gereinigt und angefeuchtet wurde. Auf diesen feuchten Untergrund wurde mit einem Pinsel eine wäßrige Dispersion aufgetragen, die als organisches Bindemittel ein Mischpolymerisat von Vinylpropionat mit Vinylacetat und mit Vinylchlorid zusammen mit geringeren Mengen Polyvinylpropionat enthielt. Man wartete so lange, bis der Untergrund den Anstrich aufgesogen hatte, und trug vor dem Trocknen den Gipsmörtel auf. Example In all cases, concrete was used as the substrate cleaned and moistened. A Brush an aqueous dispersion applied as an organic binder Copolymer of vinyl propionate with vinyl acetate and with vinyl chloride together contained lower amounts of polyvinyl propionate. You waited until the The surface had soaked up the paint and wore the plaster of paris before it dried on.
