Abstract

The invention relates to a plastic tape for sealing or lining large-area articles which comprises crosslinked plastic with edge strips of uncrosslinked plastic on its longitudinal edges.

Description

Die Erfindung betrifft ein Band aus Kunststoff zur Abdichtung bzw. Auskleidung von großflächigen Gegenständen.The invention relates to a tape made of plastic for sealing or Lining large objects.

Für die Herstellung von Gartenteichen und Schwimmbädern ist es bekannt, in die ausgehobene Grube Kunststoffbänder einzulegen und diese miteinander zu verkleben bzw. auch zu verschweißen. Bei Verwendung von Bändern aus Polyvinylchlorid hat sich eine Klebetechnik durchgesetzt, wogegen bei Bändern aus Polyäthylen die Möglichkeit einer Schweißverbindung besteht.It is for the production of garden ponds and swimming pools known to insert plastic tapes in the excavated pit and to glue them together or to weld them. At Use of tapes made of polyvinyl chloride has become a problem Adhesive technology prevailed, whereas with tapes made of polyethylene Possibility of a welded connection.

In der Bedachungstechnik sind bereits Bahnen aus Kunststoff bzw. aus gummielastischen Werkstoffen bekannt, die durch Kleben oder Schweißen an ihren Randbereichen miteinander verbunden sind. In roofing technology, sheets are already made of plastic rubber-elastic materials known by gluing or welding are connected to one another at their edge regions.  

Bei allen diesen Anwendungsfällen handelt es sich um thermoplastische Kunststoffe, die nicht vernetzt sind und aus diesem Grunde ohne größere Schwierigkeiten miteinander verschweißt oder verklebt werden können. Unvernetzte Kunststoffe haben jedoch gegenüber vernetzten Kunststoffen den Nachteil, daß ihre mechanische Festigkeit, ihre Beständigkeit gegen erhöhte Temperaturen und gegen Chemikalien wesentlich geringer ist.All of these applications are thermoplastic Plastics that are not networked and therefore without major difficulties are welded or glued together can. However, uncrosslinked plastics have crosslinked Plastics the disadvantage that their mechanical strength, their Resistance to elevated temperatures and chemicals is much lower.

Vernetzte Kunststoffe haben gegenüber den thermoplastischen Kunststoffen den wesentlichen Nachteil, daß eine Verbindung durch Kleben oder Schweißen nicht dauerhaft möglich ist.Cross-linked plastics have compared to the thermoplastic Plastics the main disadvantage that a connection through Gluing or welding is not possible permanently.

Der vorliegenden Erfindung liegt von daher die Aufgabe zugrunde, ein Band für den eingangs erwähnten Zweck zu schaffen, mit dem eine großflächige Abdichtung bzw. Auskleidung möglich ist, die dauerhaft dichte Schweißnähte aufweist und darüber hinaus die vorteilhaften Eigenschaften eines vernetzten Werkstoffes zeigt.The present invention is therefore based on the object To create tape for the purpose mentioned at the beginning with which one Large-scale sealing or lining is possible, which is permanent has tight welds and also the advantageous Shows properties of a cross-linked material.

Diese Aufgabe wird bei einem Band der eingangs erwähnten Art dadurch gelöst, daß das Band aus vernetztem Kunststoff mit an seinen Längskanten befindlichen Randstreifen aus unvernetztem Kunststoff besteht. Dadurch, daß die Randstreifen aus unvernetztem Kunststoff bestehen, kann das Band an seinen Bandkanten miteinander verschweißt werden und somit eine großflächige dichte Abdeckung erzielt werden. Mit besonderem Vorteil ist der vernetzte Kunststoff ein Polyäthylen, dem Silangruppen aufgepfropft sind und welches in Anwesenheit von Feuchtigkeit vernetzt ist. Bei der Herstellung dieses Werkstoffes kann auf die bisher übliche Vernetzung mittels energiereicher Strahlung verzichtet werden. Der Werkstoff ist darüber hinaus ohne besondere Vorkehrungen vernetzbar, da in der Atmosphäre genügend Feuchtigkeit für die Vernetzung vorhanden ist. Die Randstreifen bestehen ebenfalls aus Polyäthylen, dem jedoch Peroxide zugefügt sind. Dadurch ist es möglich, durch Erwärmung der Schweißnaht über die Zersetzungstemperatur der Peroxide eine Vernetzung der Schweißnaht zu erreichen, so daß die gesamte Lage der Abdichtung bzw. Auskleidung aus vernetztem Kunststoff besteht. This task is achieved with a tape of the type mentioned solved that the tape made of cross-linked plastic with his Longitudinal edges of non-cross-linked plastic consists. The fact that the edge strips made of non-crosslinked plastic exist, the tape can be welded together at its tape edges be and thus a large-area tight coverage can be achieved. The cross-linked plastic is particularly advantageous as a polyethylene, the silane groups are grafted on and which in the presence of Moisture is cross-linked. In the manufacture of this material can rely on the usual networking using high-energy Radiation are dispensed with. The material is also without Special precautions can be networked, as there are enough in the atmosphere Moisture is available for cross-linking. The edge strips are also made of polyethylene, but peroxides are added are. This makes it possible to heat the weld over the decomposition temperature of the peroxides is a crosslinking of the To reach the weld seam so that the entire layer of the seal or Lining made of cross-linked plastic.  

Es hat sich weiterhin als vorteilhaft erwiesen, daß das Band eine einseitige Beschichtung aus einem Kleber oder aus einer Dicht­ und/oder Korrosionsschutzmasse aufweist. Durch diese Beschichtung ist das Band mit dem abzudichtenden bzw. auszukleidenden Gegenstand porenfrei verbindbar. Das Band ist zweckmäßigerweise einstückig durch Koextrusion extrudiert. Das bedeutet, daß das Band gemäß der Lehre der Erfindung in nahezu unendlichen Längen herstellbar ist.It has also proven to be advantageous that the tape has a one-sided coating from an adhesive or from a sealing and / or has anti-corrosion compound. Because of this coating the tape with the object to be sealed or lined connectable without pores. The band is expediently in one piece Coextrusion extruded. That means the tape according to the teaching the invention can be produced in almost infinite lengths.

Die Erfindung betrifft weiterhin ein Verfahren zur Herstellung einer Abdichtung oder Auskleidung von Gegenständen. Hierbei werden die Bänder auf den Gegenstand aufgelegt, die Randstreifen durch Schmelzschweißen, vorzugsweise durch Spiegelschweißen, flüssigkeitsdicht miteinander verschweißt und anschließend die Schweißnähte über die Zersetzungstemperatur des Peroxids erwärmt und dadurch die Vernetzung der Randstreifen bewirkt. Ein dichtes Anliegen der Auskleidung bzw. Abdeckung erreicht man vorteilhafterweise dadurch, daß man die aus den Bändern hergestellte Auskleidung bzw. Abdeckung über den Schmelzpunkt des Klebers bzw. der Dicht- oder Korrosionsschutzmasse erwärmt und das Band gegen die Oberfläche des auszukleidenden bzw. zu beschichtenden Gegenstandes preßt.The invention further relates to a method for producing a Sealing or lining objects. Here, the Ribbons placed on the object, the edge strips through Fusion welding, preferably by mirror welding, welded together liquid-tight and then the Welds heated above the decomposition temperature of the peroxide and thereby networking the edge strips. A close concern the lining or cover is advantageously achieved in that the lining or Covering over the melting point of the adhesive or the sealing or Corrosion protection compound heated and the tape against the surface of the object to be lined or coated.

Alternativ kann man eine Abdichtung oder Auskleidung unter Verwendung des obengenannten Bandes auch dadurch erreichen, daß man die Bänder in unvernetztem Zustand auf den Gegenstand auflegt, die Berührungskanten der Bänder miteinander durch Schmelzschweißen verbindet, die Schweißnähte der Randbereiche durch Erwärmung über die Zersetzungstemperatur des Peroxids vernetzt und anschließend die Bänder in Gegenwart von Feuchtigkeit vernetzt. Diese Verfahrenstech­ nik läßt sich sinnvollerweise nur mit einem feuchtigkeitsvernetzbaren Polyäthylen anwenden. In Fällen, wo es nicht auf eine hohe Zugfestigkeit der Schweißnaht ankommt, sondern nur eine hohe Dichtigkeit erwartet wird, kann unter Umständen auf gesonderte Randstreifen verzichtet werden, sofern es gelingt, eine Vernetzung des Kunststoffes vor dem Verschweißen der Bandkanten weitestgehend zu vermeiden. Dies kann beispielsweise dadurch gelingen, daß man bei der Herstellung des Bandes durch Extrusion die Gegenwart von Feuchtigkeit vermeidet und die Bänder luftdicht verpackt, bis zum Anwendungsort transportiert und dort möglichst schnell verarbeitet. Nach dem Verschweißen der Bandkanten setzt dann eine allmähliche Vernetzung ein, die durch erwärmten Wasserdampf noch beschleunigt werden kann. Eine vorzeitige Vernetzung der Bandkanten kann man auch dadurch verhindern, daß man die Bandkanten mit einer feuchtigkeits­ undurchlässigen abziehbaren Folie beschichtet.Alternatively, one can use a seal or liner of the above-mentioned volume can also be achieved by moving the bands hangs on the object in a non-networked state Contact edges of the strips with each other by fusion welding connects, the welds of the edge areas by heating over the Decomposition temperature of the peroxide and then the Ribbons cross-linked in the presence of moisture. This procedural tech nik can only be used with a moisture-crosslinkable Use polyethylene. In cases where it is not high Tensile strength of the weld arrives, but only a high one Tightness may be expected to be separate Edge strips are dispensed with, provided that it succeeds in networking of the plastic as far as possible before welding the strip edges avoid. This can be achieved, for example, in that Production of the tape by extrusion the presence of moisture avoids and the tapes packed airtight, to the place of use  transported and processed there as quickly as possible. After this Welding the strip edges then sets a gradual crosslinking a, which can be accelerated by heated water vapor. You can also prematurely crosslink the ribbon edges prevent the tape edges from being damp impermeable peelable film coated.

Die Erfindung ist anhand der in den Fig. 1 bis 4 schematisch dargestellten Ausführungsbeispiele näher erläutert.The invention is explained in more detail with reference to the exemplary embodiments shown schematically in FIGS. 1 to 4.

Die Fig. 1 zeigt zwei Bänder 1 gemäß der Lehre der Erfindung, deren Mittelbereich 2 aus Polyäthylen bestehen, dem Silangruppen aufgepfropft sind, so daß das Polyäthylen bei Gegenwart von Feuchtigkeit vernetzbar ist. An die Mittelbereiche 2 sind Randstreifen 3 a und 3 b anextrudiert, die aus Polyäthylen bestehen, dem Peroxide zugegeben sind. Die Bänder 1 sind durch Koextrusion hergestellt, d. h. die Randstreifen 3 a und 3 b sind fest mit den Mittelbereichen 2 verbunden. Die Mittelbereiche 2 sind üblicherweise vernetzt, wogegen die Randstreifen 3 a und 3 b unvernetzt, jedoch vernetzbar sind. Die Randbereiche 3 a und 3 b zweier Bänder können somit, wie bei 4 dargestellt, durch Schmelzschweißen, vorzugsweise durch Spiegelschweißen, miteinander flüssigkeitsdicht verbunden werden. Durch Verbindung einer Vielzahl derartiger Bänder können großflächige Abdecklagen in einfacher Weise hergestellt werden. Die Fig. 2 zeigt ein Anwendungsbeispiel für Bänder gemäß der Lehre der Erfindung. Es ist dort ein Satteldach dargestellt, bei dem die Bänder 1 über den First einstückig von Traufe zu Traufe verlegt sind, wobei ihre Randbereiche, wie bei 4 dargestellt, miteinander verschweißt sind. Die Bänder 1 sind auf einer Oberfläche mit einem geeigneten Kleber oder einer Dicht- oder Korrosionsschutzmasse beschichtet, so daß sie auf dem Dach durch Erwärmen der Bänder über den Schmelzpunkt der Masse befestigt werden können. 1m Bereich der Traufen können die Enden der Bänder 1 zwecks Bildung einer Regenrinne hochgezogen werden, so daß auf gesonderte Regenrinnen bei der dargestellten Konstruktion verzichtet werden kann. Fig. 1 shows two tapes 1 according to the teaching of the invention, the central region 2 consist of polyethylene, the silane groups are grafted on, so that the polyethylene can be crosslinked in the presence of moisture. Edge strips 3 are connected to the central portions 2 a and 3 b extruded onto which consist of polyethylene, the peroxides are added. The strips 1 are produced by coextrusion, ie the edge strips 3 a and 3 b are firmly connected to the central regions 2 . The middle areas 2 are typically crosslinked, whereas the edge strip 3 a and 3 b uncrosslinked, but are crosslinkable. The edge regions 3 a and 3 b of two strips can thus, as shown at 4, be connected to one another in a liquid-tight manner by fusion welding, preferably by mirror welding. By connecting a large number of such tapes, large-area cover layers can be produced in a simple manner. FIG. 2 shows an application example for tapes according to the teaching of the invention. A saddle roof is shown there, in which the strips 1 are laid in one piece over the ridge from eaves to eaves, their edge regions, as shown at 4, being welded to one another. The tapes 1 are coated on one surface with a suitable adhesive or a sealing or corrosion protection compound, so that they can be attached to the roof by heating the tapes above the melting point of the mass. In the area of the eaves, the ends of the strips 1 can be pulled up to form a gutter, so that separate gutters can be dispensed with in the construction shown.

In der Fig. 3 ist die Ausbildung einer Stumpfnaht zwischen zwei Bändern dargestellt, bei der ein Heizspiegel 5 die Randbereiche 3 a und 3 b auf Schmelztemperatur erwärmt, wonach die erwärmten Flächen zwecks Bildung der Schweißnaht 4 gegeneinandergepreßt werden.In FIG. 3, the formation of a butt weld is shown between two strips, in which a heating mirror 5 heats the edge portions 3 a and 3 b to melting temperature, after which the heated surfaces are pressed against each to form the weld seam 4.

Die Fig. 4 zeigt eine Oberlapptnaht, bei der die Randbereiche 3 a und 3 b übereinandergelegt und der Heizspiegel 5 zwischen diesen gelegen ist. Wie in der Fig. 3 wird der Heizspiegel 5 in Längsrichtung der Bandkanten bewegt und die Bandkanten gegeneinandergepreßt. Nach dem Herstellen der Schweißnaht 4 wird die Schweißnaht 4, beispielsweise mittels Warmluft, soweit erwärmt, daß die in dem Material der Randbereiche 3 a und 3 b befindlichen Peroxide zersetzt werden und somit eine Vernetzung der Randbereiche 3 a und 3 b erreicht wird. Die Befestigung der Bänder 1 auf der Unterkonstruktion des Daches geschieht durch Erwärmung der Bänder 1 und anschließendes Anpressen der Bänder an die Unterkonstruktion. Fig. 4 shows an upper lap seam, in which the edge regions 3 a and 3 b are superimposed and the heating mirror 5 is located between them. As in FIG. 3, the heating mirror 5 is moved in the longitudinal direction of the band edges and the band edges are pressed against one another. After the weld 4 has been produced , the weld 4 is heated, for example by means of warm air, to such an extent that the peroxides located in the material of the edge regions 3 a and 3 b are decomposed and thus the edge regions 3 a and 3 b are cross-linked. The strips 1 are fastened to the substructure of the roof by heating the strips 1 and then pressing the strips onto the substructure.

Auf eine Vernetzung der Bereiche 2 der Bänder 1 vor der Verlegung kann bei der Verwendung von feuchtigkeitsvernetztem Polyäthylen verzichtet werden, da dieses aufgrund der in der Atmosphäre befindlichen Feuchtigkeit von selbst vernetzt.A cross-linking of the areas 2 of the tapes 1 before laying can be dispensed with when using moisture-cross-linked polyethylene, since this cross-links by itself due to the moisture in the atmosphere.
