Abstract
Description
Die vorliegende Erfindung betrifft eine Kunststoffbahn, welche die Wasserdampfdiffusion verhindert oder zumindest wesentlich reduziert, ein Verfahren zur Herstellung dieser Kunststoffbahn sowie deren Verwendung.The present invention relates to a plastic sheet which prevents or at least substantially reduces water vapor diffusion, a method for producing this plastic sheet and its use.
Im Stand der Technik existieren die verschiedensten Arten von Dampfsperren und Dampfbremsen.The most varied types of vapor barriers and vapor barriers exist in the prior art.
Der hohe Dampfdiffusionswiderstand wird je nach Produkt durch Polyethylen, Aluminium, Bitumen oder eine Wachsschicht erzeugt.Depending on the product, the high vapor diffusion resistance is generated by polyethylene, aluminum, bitumen or a wax layer.
Dampfsperren auf der Basis geblasener Polyethylen-Folien weisen den Nachteil eines hohen Ausdehnungskoeffizienten auf. Daraus resultieren grosse Wärmebewegungen, welche zu verschiedenen Problemen führen. Dabei hat die Laminierung eines Polyester-Gittergewebes zwischen zwei Polyethylen-Folien nicht zur endgültigen Losung der Probleme geführt.Vapor barriers based on blown polyethylene films have the disadvantage of a high expansion coefficient. This results in large thermal movements, which lead to various problems. The lamination of a polyester mesh fabric between two polyethylene films did not lead to the final solution to the problems.
Aluminium-Dampfsperren, unabhängig davon ob es sich um reine Aluminiumfolien, Verbundfolien mit Kunststoffbeschichtung oder Laminate mit Kraftpapier handelt, haben den Nachteil, dass sich Anschlüsse und Abschlüsse bei Durchdringungen sowie am Dachrand aufgrund der minimalen Verdehnbarkeit nur schlecht ausführen lassen. Zudem sind die Produkte undurchsichtig und weisen eine glatte, relativ rutschige Oberfläche auf. Gegenüber Verbundmaterialien von Aluminium mit anderen Stoffen sind zudem Vorbehalte aus oekologischer Sicht angebracht, da ein Recycling kaum möglich ist.Aluminum vapor barriers, regardless of whether they are pure aluminum foils, composite foils with plastic coating or laminates with kraft paper, have the disadvantage that connections and closings in penetrations and on the roof edge are difficult to carry out due to the minimal elasticity. In addition, the products are opaque and have a smooth, relatively slippery surface. Ecological considerations regarding composite materials of aluminum with other substances are also appropriate, since recycling is hardly possible.
Dampfsperren und Dampfbremsen auf der Basis von Bitumen weisen ähnliche Nachteile wie Aluminium-Dampfsperren auf. Auch hier lassen sich Anschlüsse und Abschlüsse im allgemeinen schlecht ausführen. Vorbehalte an der oekologischen Unbedenklichkeit sind ebenfalls angebracht.Vapor barriers and vapor barriers based on bitumen have similar disadvantages as aluminum vapor barriers. Here, too, connections and terminations are generally difficult to implement. There are also reservations about ecological safety.
Gewachste Kraftpapiere lassen sich nicht verdehnen und reissen leicht. Zusätzlich bereitet hier die dauerhafte, luftdichte Verbindung der einzelnen Bahnen Probleme.Waxed kraft papers cannot be stretched and tear easily. In addition, the permanent, airtight connection of the individual webs creates problems here.
Es ist das Ziel der vorliegenden Erfindung, die oben genannten Nachteile zu beseitigen.It is the object of the present invention to overcome the drawbacks mentioned above.
Es ist ein weiteres Ziel der vorliegenden Erfindung, eine Kunststoffbahn zur Verfügung zu stellen, welche keine Halogene, kein Polyvinylchlorid, kein Bitumen und keine Schwermetalle, wie etwa Blei und Cadmium, enthält.It is a further object of the present invention to provide a plastic sheet which does not contain halogens, no polyvinyl chloride, no bitumen and no heavy metals such as lead and cadmium.
Diese neue Kunststoffbahn soll auch beliebig kombiniert und durch Verkleben oder Verschweissen verbunden werden können mit einer Kunststoffdichtungsbahn, wie sie beispielsweise in der Europäischen Patentschrift Nr. 0 428 851 B1 beschrieben ist, oder mit einer porösen Kunststoffbahn auf der Basis von Polyolefinen, wie sie beispielsweise in einer gleichzeitig eingereichten und ein Prioritätsdatum (19. April 1994) festlegenden Schweizerischen Patentanmeldung mit dem Titel "Kunststoffbahn" definiert ist.This new plastic sheet should also be combined as desired and connected by gluing or welding with a plastic sealing sheet, as described for example in European Patent No. 0 428 851 B1, or with a porous plastic sheet based on polyolefins, as described for example in a simultaneously filed and a priority date (April 19, 1994) Swiss patent application entitled "Plastic Railway" is defined.
Es ist ein weiteres Ziel der vorliegenden Erfindung, eine Kunststoffbahn zur Verfügung zu stellen, welche in der Anwendung und Verarbeitung einfach handzuhaben ist.It is another object of the present invention to provide a plastic sheet which is easy to use and process.
Diese Kunststoffbahn soll vorzugsweise auch durchscheinend (transluszent) sein.This plastic sheet should preferably also be translucent.
Diese Kunststoffbahn soll auf der Basis von kostengünstigen Rohstoffen aufgebaut sein und mittels kostengünstigen Verfahren hergestellt werden können.This plastic web should be built on the basis of inexpensive raw materials and should be able to be manufactured using inexpensive processes.
Diese neue Kunststoffbahn soll auch an plattenförmige Materialien fixiert werden können, welche der Wärmeisolation und/oder dem Schallschutz und/oder dem Brandschutz dienen.This new plastic sheet should also be able to be fixed to plate-shaped materials which serve for thermal insulation and / or sound insulation and / or fire protection.
Die Rohstoffe sollen derart gewählt sein, dass die daraus hergestellte Kunststoffbahn recykliert werden kann, insbesondere gemeinsam mit der oben erwähnten Kunststoffdichtungsbahn und der oben erwähnten porösen Kunststoffbahn.The raw materials should be selected such that the plastic sheet produced therefrom can be recycled, in particular together with the above-mentioned plastic sealing sheet and the above-mentioned porous plastic sheet.
Diese neue Kunststoffbahn soll vorzugsweise auf der Basis von Polyolefinen aufgebaut sein und insbesondere einen kleineren Ausdehnungskoeffizienten aufweisen als herkömmliche geblasene Polyolefin-Folien.This new plastic sheet should preferably be based on polyolefins and in particular should have a smaller expansion coefficient than conventional blown polyolefin films.

Die erfindungsgemässen Kunststoffbahnen können eine rutschfeste Oberfläche aufweisen.The plastic sheets according to the invention can have a non-slip surface.
Die erfindungsgemässen Kunststoffbahnen enthalten keine Halogene, kein Polyvinylchlorid, kein Bitumen, keine Schwermetalle, wie etwa Blei und Cadmium, und kein metallisches Aluminium.The plastic sheets according to the invention contain no halogens, no polyvinyl chloride, no bitumen, no heavy metals, such as lead and cadmium, and no metallic aluminum.
Bei der Produktion und bei der Verlegung entstehen nahezu keine Emissionen.There are almost no emissions during production and installation.
Die Bahn ist rezyklierbar. Die Entsorgung durch Verbrennung oder Deponierung ist unbedenklich.The web is recyclable. Disposal by incineration or landfill is harmless.
Deshalb sind die erfindungsgemässen Kunststoffbahnen oekologisch unbedenklich.Therefore, the plastic sheets according to the invention are ecologically harmless.
Die erfindungsgemässe Kunststoffbahn ist vorzugsweise durchscheinend (transluszent).The plastic sheet according to the invention is preferably translucent (translucent).
Dadurch bleiben Markierungen auf der Unterlage oder Unterkonstruktion sichtbar. Dadurch wird die Anwendung vereinfacht.As a result, markings on the base or substructure remain visible. This simplifies the application.
Die Verarbeitung der erfindungsgemässen Kunststoffbahn kann auf verschiedene Weisen erfolgen. Die erfindungsgemässen Kunststoffbahnen können mit geeigneten Klebebändern oder Klebemassen, z.B. aus Polyisobutylen, miteinander verbunden werden. Sie können aber auch mit Heissluft- oder Heizkeilgeräten maschinell oder von Hand miteinander verschweisst werden.The plastic web according to the invention can be processed in various ways. The plastic webs according to the invention can be connected to one another with suitable adhesive tapes or adhesive compositions, for example made of polyisobutylene. But you can also use Hot air or hot wedge devices are welded to one another mechanically or by hand.
