Abstract

Paper which is to be coated with a setting-retardant for concrete is coated on both sides with plastics, specifically polyethylene. The paper si placed on selected areas of concrete surfaces to prevent them from setting whilst allowing non-covered area to set. The paper is then removed and those zones that have remained non-set are washed away so that the remaining (set) zones represent a predetermined pattern or design, e.g. on facades of buildings. Sizing the paper with polyethylene ensures even and all-over contact of the paper with the concrete surface enabling the setting-retardant to act as intended.

Description

Papier zur Beschichtung mit einem Abbindeverzögerer Paper to be coated with a setting retarder

Die Erfindung betrifft ein Papier zur Beschichtung mit einem Abbindeverzögerer für die Herstellung von Waschbeton.The invention relates to a paper for coating with a setting retarder for the production of exposed aggregate concrete.

Es ist bekannt, Papier einseitig mit einem Abbindeverzögerer zu beschichten, um es mit dieser Seite auf die Oberfläche eines Waschbetons zu legen, damit diese Oberflache nicht sofort abbindet. Nach Abbinden der übrigen Betonschicht wird das Papier von der Betonoberfläche abgezogen und die nicht abgebundene Schicht zwischen den Kieseln bzw. dem groben Zuschlagstoff ausgewaschen.It is known to coat paper on one side with a setting retarder, to lay it with this side on the surface of an exposed aggregate concrete so that this Surface does not set immediately. After the rest of the concrete layer has set, the Paper peeled off the concrete surface and the uncured layer between washed out the pebbles or the coarse aggregate.

Es hat sich gezeigt, daß während des Abbindens der von dem Papier entfernteren Betonschicht das Papier häufig von der Betonoberfläche teilweise abhebt, so daß ein gleichmäßiges Eindringen des Abbindeverzögerers in die obere Betonschicht nicht gewährleistet ist. Dies führt zu ungleichmäßigen und unschönen Waschbetonoberflächen.It has been found that during the setting of the paper more distant concrete layer often partially lifts the paper from the concrete surface, so that a uniform penetration of the setting retarder into the upper concrete layer is not guaranteed. This leads to uneven and unsightly exposed aggregate concrete surfaces.

Besonders unangenehm macht sich eine nicht vollflächige Anlage des Papiers dann bemerkbar, wenn das Papier nur stellenweise mit Abbindeverzögerern beschichtet ist, um hierdurch ausgewaschene und unbearbeitete Betonoberflächenteile in einem bestimmten Muster zu erhalten. Ein nicht exaktes Anhaften des Papiers führt an den Grenzlinien zwischen ausgewaschenen und nicht bearbeiteten Oberflächenteilen zu ungenauen und verschwommenen Ubergängen. Darüber hinaus hat es sich bei partiell mit Verzögerer beschichtetem Papier gezeigt, daß nach dem Abbinden die nicht mit Verzögerer beschichteten Papierflächen an der Betonoberfläche derart fest anhaften, daß sie nur durch eine zusätzliche zeitraubende Bearbeitung entfernt werden können.A not full-surface system is particularly uncomfortable of Paper is noticeable if the paper only has a setting retarder in places is coated to thereby wash out and unprocessed concrete surface parts to get in a certain pattern. Imprecise adhesion of the paper results at the boundary lines between washed out and unprocessed parts of the surface to imprecise and blurred transitions. In addition, there has been a partial paper coated with retarder shown that after setting the not with Retarder-coated paper surfaces adhere to the concrete surface so firmly that that they can only be removed by additional time-consuming processing.

Aufgabe der Erfindung ist es, ein Papier zur Beschichtung mit einem Abbindeverzögerer zu schaffen, das während der Auflage auf der Betonoberfläche sich von dieser nicht teilweise abhebt.The object of the invention is to provide a paper for coating with a Setting retarder to create the during the application on the concrete surface does not partially differ from this.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das Papier auf beiden Seiten mit Kunststoff beschichtet ist.According to the invention, this object is achieved in that the paper is coated with plastic on both sides.

Ein derartiges mit einer Abbindeverzögerungsschicht versehenes Papier bleibt frei von Spannungen vollflächig an der Betonoberfläche haften, so daß der Verzögerer gleichmäßig in den Beton eindringt. Bei einem partiell beschichteten Papier entstehen exakte Grenzen zwischen ausgewaschenen und unbearbeiteten Betonoberflächenteilen. Auch nicht mit Verzögerer versehene Papierflächen lassen sich nach dem Abbinden leicht von der Betonoberfläche abziehen.Such a paper provided with a setting retardation layer remains free of tension over the entire surface of the concrete surface, so that the Retarder penetrates evenly into the concrete. In the case of a partially coated Paper creates exact boundaries between washed out and unprocessed concrete surface parts. Even paper surfaces not provided with retarder can be removed after setting easily peel off the concrete surface.

Als besonders vorteilhafter Kunststoff hat sich Polyäthylen erwiesen. Ferner wird vorgeschlagen, daß das Papier durch Wahl der Grundbestandteile und/oder der Zusätze dimensionsstabil ist, um ein Arbeiten des Papiers zu verhindern.Polyethylene has proven to be a particularly advantageous plastic. It is also suggested that the paper by Choice of basic ingredients and / or the additive is dimensionally stable in order to prevent the paper from working.

Vorzugsweise kann das Papier ein Gewicht von 80 bis 150 g/m2 besitzen, wobei sich als besonders vorteilhaft ein Gewicht 2 von 110 g/m2 erwiesen hat. Eine günstige Aufnahmefähigkeit der Kunststoffoberfläche für die Verzögerungsschicht wird dadurch erreicht, daß die Oberfläche zumindest der Kunststoff- bzw. Polyäthylenschicht, die den Abbindeverzögerer aufnimmt, einen Benetzungswert von >35 dyn/cm aufweist.The paper can preferably have a weight of 80 to 150 g / m2, a weight 2 of 110 g / m2 has proven to be particularly advantageous. One favorable absorption capacity of the plastic surface for the delay layer is achieved in that the surface of at least the plastic or polyethylene layer, which absorbs the setting retarder, has a wetting value of> 35 dyn / cm.

Vorzugsweise wird vorgeschlagen, daß das Papier nur partiell mit einem Abbindeverzögerer beschichtet ist.It is preferably proposed that the paper only partially with a Setting retarder is coated.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung in einem Ausschnitt geschnitten dargestellt und wird im folgenden näher beschrieben.An embodiment of the invention is shown in the drawing in one Section shown in section and is described in more detail below.

Ein Papier 1 mit einer Fläche in der Größe der Oberfläche des 2 Waschbetonsteins und einem Gewicht von 110 g/m2 ist beidseitig mit einer eine glänzende Oberfläche aufweisenden Polyäthylenschicht 2a, 2b in einer Stärke von 20 g/m2 beschichtet. Zumindest diejenige Polyäthylenschicht 2b, die den Abbindeverzögerer 3 aufnehmen soll, ist an ihrer Oberfläche mit physikalischen oder chemischen Mitteln, z.B. eine Hochfrequenzentladung, derart behandelt, daß ein Benetzungswert von 38-40 dyn/cm entsteht. Auf diese Polyäthylenschicht 2b ist der auf nicht wäßriger Basis aufgebaute Abbindeverzögerer 3 2 in einer Stärke von 65-70 g/m2 aufgetragen. Die Verzögerungsschicht besteht aus dem Verzögerer und einem Füllstoff, welcher in Form einer organisches Lösungsmittel enthaltenden Paste aufgebracht ist.A paper 1 with an area the size of the surface of the 2 exposed aggregate concrete block and a weight of 110 g / m2 has a glossy surface on both sides having polyethylene layer 2a, 2b coated in a thickness of 20 g / m2. At least the polyethylene layer 2b that absorbs the setting retarder 3 is on its surface by physical or chemical means, e.g. a High frequency discharge treated so that a wetting value of 38-40 dynes / cm arises. On top of this polyethylene layer 2b is the one built up on a non-aqueous basis Setting retarder 3 2 applied in a thickness of 65-70 g / m2. The delay layer consists of the retarder and a filler, which is in the form of an organic Solvent-containing paste is applied.
