Abstract

The method of producing sealing material (1) consisting of at least one lower and upper support layer or web (2,3) between which is a plastic layer (4) containing clay and liquid, involves applying the clay material to the web as a dry layer. The second web is placed on the dry layer to form a laminar structure treated in a processing unit The outer support layers are joined such as loosely sewn together before the liquid-treatment.

Description

Die Erfindung bezieht sich auf ein Verfahren zum Herstellen eines Dichtungsmaterials gemäß Oberbegriff Patentanspruch 1.The invention relates to a method for producing a sealing material according to the preamble of claim 1.

Dichtungsmaterialien dieser Art sind grundsätzlich bekannt (EP 658 231, US 4,534,925).Sealing materials of this type are generally known (EP 658 231, US 4,534,925).

Aufgabe der Erfindung ist es, ein Verfahren aufzuzeigen, mit dem die Herstellung eines solchen Dichtungsmaterials mit vereinfachten Mitteln möglich ist. Zur Lösung dieser Aufgabe ist ein Verfahren entsprechend dem Patentanspruch 1 ausgebildet.The object of the invention is to demonstrate a method by which the production of such a sealing material is possible with simplified means. To the solution this object is a method according to claim 1 is formed.

Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche. Die Erfindung wird im folgenden anhand der Figuren an einem Ausführungsbeispiel näher erläutert. Es zeigen:Developments of the invention are the subject of the dependent claims. The invention is explained in more detail below with reference to the figures using an exemplary embodiment. Show it:

Fig. 1 in vereinfachter Darstellung einen Schnitt durch eine Dichtungsmatte; FIG. 1 is a simplified representation of a section through a sealing mat;

Fig. 2 in vereinfachter Darstellung ein Verfahren gemäß der Erfindung zum Herstellen der Dichtungsmatte der Fig. 1. FIG. 2 shows a simplified representation of a method according to the invention for producing the sealing mat of FIG. 1.

Die in den Figuren allgemein mit 1 bezeichnete Dichtungsmatte besteht aus einer Trägerbahn 2 und einer oberen Abschlußbahn 3 sowie einer zwischen diesen Bahnen angeordneten, wasserabhaltenden bzw. wasserundurchlässigen Schicht 4. Die Schicht 4 enthält im wesentlichen Ton, wobei beispielsweise zumindest ein gewisser Anteil des Tons Smektit-Ton ist, sowie eine Flüssigkeit, die zumindest zum Teil Wasser ist. Weiterhin enthält die Schicht 4 auch ein Bindemittel, beispielsweise in Form von Zellulose. Der Flüssigkeitsanteil der Schicht 4 ist so gewählt, daß diese plastisch verformbar ist. Die äußeren Bahnen 2 und 3 sind durch die Schicht 4 hindurch locker vernäht, wie dies mit den Fäden 5 angedeutet ist, und zwar ohne Reduzierung der Dicke der Schicht 4 im Bereich dieser Vernähung. Die Bahnen 2 und 3 bestehen aus einem geeigneten Flachmaterial, beispielsweise aus Gewebe oder aus einem gewebeverstärkten Folien- oder Vliesmaterial (z. B. Non-Woven-Material).The sealing mat, generally designated 1 in the figures, consists of a carrier web 2 and an upper end web 3 and a water-repellent or water-impermeable layer 4 arranged between these webs. Layer 4 essentially contains clay, for example at least a certain proportion of the clay being smectite clay, and a liquid which is at least partly water. Layer 4 also contains a binder, for example in the form of cellulose. The liquid portion of the layer 4 is selected so that it is plastically deformable. The outer webs 2 and 3 are loosely sewn through the layer 4 , as indicated by the threads 5 , without reducing the thickness of the layer 4 in the area of this stitching. The webs 2 and 3 consist of a suitable flat material, for example of fabric or of a fabric-reinforced film or non-woven material (e.g. non-woven material).

Die Fig. 2 zeigt die Herstellung des Dichtungsmaterials 1. Auf die von einer Rolle 6 abgezogene Bahn 2 wird mittels einer geeigneten Streueinrichtung 3 der die spätere Schicht 4 bildende Ton gegebenenfalls in Mischung mit weiteren Bestandteilen im wesentlichen im trockenen Zustand als Streuschicht 4' aufgebracht. Im Anschluß daran wird an einer Laminier-Station 8 auf die Streuschicht 4' die ebenfalls von einer Rolle 9 abgezogene Bahn 3 aufgelegt und die beiden Schichten 2 und 3 durch die Streuschicht 4 hindurch in der Näheinrichtung 10 lose miteinander vernäht. Das so hergestellte Mehrschicht-Material 1' wird dann in einer Station 11 einer Flüssigkeitsbehandlung unterzogen. Die Station 11 besteht im einfachsten Fall aus wenigstens einer, sich quer zur Bahn 1' erstreckenden Düsenanordnung 12, mit der die Flüssigkeit, nämlich beispielsweise Wasser oder Wasser mit weiteren Zusätzen auf die Bahn 1' dosiert aufgebracht wird, daß die im wesentlichen trockene Streuschicht 4' in die plastische Schicht 4 umgeformt wird. Anschließendes Walzen in der die Walzzylinder 13 aufweisenden Station 14 wird schließlich für die Schicht 4 die vorgegebene Dicke eingestellt. Fig. 2 shows the preparation of the sealing material 1. On the web 2 drawn off from a roll 6, the clay forming the later layer 4 is applied by means of a suitable scattering device 3, optionally in a mixture with other constituents, essentially in the dry state as a scattering layer 4 '. Subsequently, at a laminating station 8 , the web 3 , likewise drawn off from a roll 9, is placed on the scattering layer 4 'and the two layers 2 and 3 are loosely sewn together in the sewing device 10 through the scattering layer 4 . The multilayer material 1 'thus produced is then subjected to a liquid treatment in a station 11 . In the simplest case, the station 11 consists of at least one nozzle arrangement 12 which extends transversely to the web 1 'and with which the liquid, for example water or water, is metered onto the web 1 ' with further additives such that the essentially dry scattering layer 4 'is formed into the plastic layer 4 . Subsequent rolling in the station 14 having the rolling cylinders 13 is finally set for the layer 4, the predetermined thickness.

Die Erfindung wurde voranstehend an einem Ausführungsbeispiel beschrieben. Es versteht sich, daß Änderungen sowie Abwandlungen möglich sind. So ist es beispielsweise möglich, die Station 11 zur Behandlung mit der Flüssigkeit auch so auszubilden, daß an dieser Station die Bahn 1' durch wenigstens ein die Flüssigkeit enthaltendes Bad hindurchgeführt wird. The invention has been described above using an exemplary embodiment. It is understood that changes and modifications are possible. It is thus possible, for example, to design the station 11 for treatment with the liquid in such a way that at this station the web 1 'is passed through at least one bath containing the liquid.
