Abstract
Description
Die Erfindung betrifft eine mehrlagige und/oder mehrschichtige Dichtungsbahn mit permeationshemmender Zwischenlage oder Zwischen schicht, insbesondere polyäthylenhaltige und/oder äthylencopolymer haltige Dichtungsbahnen.The invention relates to a multilayer and / or multilayer Sealing membrane with permeation-resistant intermediate layer or intermediate layer, in particular polyethylene-containing and / or ethylene copolymer containing geomembranes.
Verschiedene Untersuchungen an Abdichtungsbahnen für Deponien haben gezeigt, daß auch der physikalische Prozeß der Permeation zu berück sichtigen ist. Die verschiedenen Kunststoffdichtungsbahnen zeigen hier nach ihrer chemischen Struktur mehr oder weniger Restdurchlässig keiten für Kohlenwasserstoffe in den die Abdichtungsbahnen be lastenden Sickerwässer. Die Ursache sind nicht Fehlstellen (Risse, Poren und Löcher oder Fügefehler) sondern ist die Permeation.Various studies on waterproofing membranes for landfills have been made demonstrated that even the physical process of permeation has to be considered is visible. The different plastic sealing sheets show here more or less permeable according to their chemical structure areas for hydrocarbons in the waterproofing membrane heavy leachate. The cause is not defects (cracks, Pores and holes or joining errors) but is the permeation.
Deshalb wird die Entwicklung von mehrlagigen aufgebauten Dichtungs bahnen mit permeationsverhindernder Sperrschicht, z. B. aus Aluminiumfolie angestrebt. Voraussetzung sollte aber sein, daß das Dehnungsverhalten der Bahnen nicht wesentlich beeinträchtigt wird.That is why the development of multi-layer seal is built webs with permeation-preventing barrier layer, e.g. B. from Aimed for aluminum foil. But the prerequisite should be that the stretch behavior of the sheets is not significantly affected becomes.
Die vorgeschlagene Aluminiumeinlage erscheint jedoch weniger geeignet, da sie der Abdichtungsbahn ein beträchtliches Maß der vorhandenen Flexibilität nimmt.However, the proposed aluminum insert appears less suitable, since they provide the waterproofing membrane a considerable measure of the existing one Flexibility takes.
Eine Deponiebasisabdichtung muß Dehnungen aufnehmen können, da Setzungen unvermeidlich sind.A landfill base seal must be able to absorb expansion, because Settlements are inevitable.
Der Erfindung liegt die Aufgabe zugrunde, eine ausreichend permeations sichere Zwischenlage für Kunststoffabdichtungen zu schaffen. Nach der Erfindung wird das mit einer Mischung aus Polysulfit und Epoxid erreicht. Sowohl Polysulfit als Epoxid sind als Dichtungsmittel jedes für sich bekannt. Beide Stoffe sind hochgradig kohlenwasser stoff- und chlorkohlenwasserstoffbeständig, aber erst die Kombination bringt einen extrem hohen Permeationswiderstand gegen diese Stoffe. The invention has for its object sufficient permeations to create a safe intermediate layer for plastic seals. To the invention is with a mixture of polysulfite and epoxy reached. Both polysulfite and epoxy are used as sealants each known for itself. Both substances are highly hydrocarbon Resistant to chemicals and chlorinated hydrocarbons, but only the combination brings an extremely high permeation resistance against these substances.
Der Epoxid-Anteil in der Mischung ist nach der Erfindung so abgestimmt, daß das Dehnverhalten der ausgehärteten Mischung mindestens gleich, am besten höher als das der darunter befindlichen Trägerbahn ist.The epoxy content in the mixture is adjusted according to the invention that the stretching behavior of the cured mixture is at least the same, is best higher than that of the carrier web underneath.
Weitere Merkmale der Erfindung sind in den Ansprüchen erläutert.Further features of the invention are explained in the claims.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung darge stellt. Mit 1 ist eine 1,5 bis 2 mm polyäthylen- bzw. äthylencopolymer haltige Dichtungsbahn bezeichnet. Im Ausführungsbeispiel ist die Bahn 2 mm dick. Die Bahn 1 ist mit einer Mischung aus Polysulfit und Epoxid beschichtet. Die Schichtdicke kann 0,2 bis 0,4 mm betragen, im Aus führungsbeispiel ist eine einheitliche Schichtdicke von 0,3 mm gegeben. Daraus ist wiederum eine äthylencopolymerhaltige Deckschicht 3 aufge bracht. Die Deckschicht kann eine Dicke zwischen 0,15 und 0,4 mm be sitzen. Im Ausführungsbeispiel ist eine Dicke von 0,3 mm vorgesehen. Die Deckschicht dient als Schutzlage für die permeationssichere Schicht 2. Ferner dient sie dazu, eine schweißungsfähige Verbindung für die Ab dichtungsbahnen untereinander herzustellen.In the drawing, an embodiment of the invention is Darge. 1 denotes a 1.5 to 2 mm polyethylene or ethylene copolymer-containing sealing membrane. In the exemplary embodiment, the web is 2 mm thick. Lane 1 is coated with a mixture of polysulfite and epoxy. The layer thickness can be 0.2 to 0.4 mm, in the exemplary embodiment there is a uniform layer thickness of 0.3 mm. This in turn is an ethylene copolymer-containing top layer 3 brought up. The cover layer can be between 0.15 and 0.4 mm thick. In the exemplary embodiment, a thickness of 0.3 mm is provided. The cover layer serves as a protective layer for the permeation-proof layer 2 . It also serves to produce a weldable connection for the sealing membranes from one another.
Die dargestellten Bahnen werden vorzugsweise in einer Breite von 1 bis 2 m hergestellt. Die Längen ergeben sich nach Bedarf mit 15 bis 50 m und mehr. Zur Herstellung einer Abdichtung werden die einzelnen Bahnen aneinandergeschweißt. Der Schweißstoß kann zusätzlich mit Polysulfit-Epoxid-Mischung im Streich- oder Sprühverfahren abgesichert werden.The webs shown are preferably in a width of Made 1 to 2 m. The lengths are 15 to 50 m and more. The individual Sheets welded together. The weld joint can also with Protected polysulfite-epoxy mixture by brushing or spraying will.
Die Polysulfit-Epoxid-Mischung läßt sich sowohl auflaminieren, auf sprühen, aufstreichen sowie auch zu einer dünnen Folie verarbeiten. Es können alle Anschlüsse, Durchdringungen der Bahn oder Schadstellen gleich mit einer kohlenwasserstoffsicheren Schicht wiederum beschichtet werden. Das ist wichtig, da eine Deponieabdichtung nicht isoliert durch die Abdichtungsbahn sondern durch ein Gesamtsystem aus Bahn und Anschlüssen und dergleichen gebildet wird und eine durchgehende Sicherung der gesamten Fläche gewährleistet sein muß. The polysulfite-epoxy mixture can be laminated on spray, spread and also process into a thin film. All connections, penetrations of the web or damaged areas can be found coated with a hydrocarbon-proof layer will. This is important because landfill sealing is not isolated through the waterproofing membrane but through an overall system of membrane and Connections and the like is formed and a continuous fuse the entire area must be guaranteed.
Die Mischung aus Polysulfit-Epoxid ist insbesondere aus wirtschaft lichen Gründen nicht geeignet, um sie allein, d. h., ohne Trägerbahn als Deponieabdichtung einzusetzen.The mixture of polysulfite epoxy is particularly economical reasons not suitable to them alone, d. that is, without a carrier web used as landfill sealing.
Die im Ausführungsbeispiel gezeigte Abdichtungsbahn kann nahtlos und sicher verlegt werden. Die Abdichtung innerhalb der eingebauten Erd schichten bleibt beweglich, sie ist gleichzeitig nagetier- und durchwurzelungsfest sowie auch im Langzeitverhalten korrosionsfest.The sealing membrane shown in the exemplary embodiment can be seamless and to be laid safely. The seal inside the built-in earth stratification remains flexible, it is both rodent and root-resistant as well as corrosion-resistant in long-term behavior.
