Bahnförmiges IsoliermaterialSheet-like insulation material
Die Erfindung betrifft ein in Form von Bahnen hergestelltes isolierendes und dichtendes Baumaterial, insbesondere Dachbahnen, jeweils bestehend aus einer beidseitig mit plastischen bis harten Kohlenwasserstoffgemischen, insbesondere Bitumen, beschichteten Folie aus einem dichten Stoff, beispielsweise Aluminium, als Dampfsperre und Trägermaterial mit einer flächigen Armierung aus Glasfaser.The invention relates to an insulating and sealing building material produced in the form of sheets, in particular roofing sheets, each consisting of a film made of a dense material, for example aluminum, coated on both sides with plastic to hard hydrocarbon mixtures, in particular bitumen, as a vapor barrier and carrier material with a flat reinforcement made of glass fiber.
Zur Herstellung von Dachbahnen mit Bitumenbeschichtungen ist es bekannt, Aluminium und Glasvlies von getrennten Rollen abzuwikkeln und gleichzeitig durch ein Bitumenbad zu führen. Dabei dringt das auf eine Temperatur von etwa 180 C erwärmte Bitumen trotz seiner hohen Viskosität von den Rändern her zwischen die Bahnen und umschließt vollständig den auf diese Weise hergestellten Verbund von Dampfsperre und Glasvlies. Beim gemeinsamen Durchgang durch das Bitumenbad besteht die Gefahr, daß die beiden Materialbahnen aufschwimmen und seitlich verlaufen. Diese Gefahr erhöht sich mit zunehmender Durchlaufgeschwindigkeit. Zur Vermeidung der vorgenannten Schwierigkeiten ist der Durchlauf auf geringe Geschwindigkeiten zu begrenzen. Geringe Durchlaufgeschwindigkeiten verursachen jedoch hohe Produktionskosten. Ein weiterer Nachteil kann sich durch eine unregelmäßige Verteilung des zwischen die Aluminium- und Vliesbahn eingedrungenen Bitumens einstellen. Damit ist die Gefahr von Delaminationen zwischen der Dampfsperre und der Vliesbahn verbunden. Auch eine ungleichmäßige Abkühlung des seitlich zwischen die zu kaschieren-To produce roofing membranes with bitumen coatings, it is known to unwind aluminum and glass fleece from separate rolls and simultaneously feed them through a bitumen bath. The bitumen, heated to a temperature of around 180°C, penetrates between the membranes from the edges despite its high viscosity and completely encloses the composite of vapor barrier and glass fleece produced in this way. When both membranes pass through the bitumen bath together, there is a risk that the two material membranes will float up and run sideways. This risk increases with increasing throughput speed. To avoid the aforementioned difficulties, the throughput should be limited to low speeds. However, low throughput speeds cause high production costs. Another disadvantage can arise from an irregular distribution of the bitumen that has penetrated between the aluminum and fleece membranes. This entails the risk of delamination between the vapor barrier and the fleece membrane. Uneven cooling of the side between the parts to be concealed
den Bahnen eindringenden Bitumens ist von Nachteil. Sie führt zu LuftbLaseneinfLüssen, und die Grenzschichten der zur Mitte dringenden Bitumenmassen können sich mitunter nicht ausreichend verb i nden.The penetration of bitumen into the sheets is a disadvantage. It leads to the ingress of air bubbles and the boundary layers of the bitumen masses penetrating to the centre cannot bond sufficiently.
Bekannt für die Herstellung von Dachbahnen ist auch die Verwendung eines beidseitig mit Kunststoff beschichteten Aluminiums aLs Dampfsperre. Das Aluminium wird, wie zuvor erläutert, zusammen mit einer Glasvliesbahn durch das Bitumenbad geführt. Die zusätzliche Kunst stoffbeschichtung des Aluminiums soLL durch AnschmeLzen den Verbund mit dem Bitumen optimieren. Die Praxis hat gezeigt, daß bei zu hohen Bitumentemperaturen die Kunst stoffbeschichtung verdampft, und somit die angestrebte Verbundwirkung nicht erreicht. Zusätzlich besteht auch hier die Gefahr des Verlaufens beim Durchführen der möglichst parallel zu haltenden Bahnen durch das Aufschwimmen im zähflüssigen Bitumen,.Another well-known method for producing roofing membranes is the use of aluminum coated with plastic on both sides as a vapor barrier. As previously explained, the aluminum is passed through the bitumen bath together with a glass fleece membrane. The additional plastic coating on the aluminum is intended to optimize the bond with the bitumen by melting it. Practice has shown that if the bitumen temperature is too high, the plastic coating evaporates and thus the desired bonding effect is not achieved. In addition, there is also a risk of running when passing the membranes, which should be kept as parallel as possible, through floating in the viscous bitumen.
Außerdem werden durch das Aufschwimmen der beiden Bahnen unterschiedlich starke Bitumenschichten zwischen den Bahnen, und damit auch unterschiedlich starke Bitumendecklagen gebildet. Durch die unterschiedlich starken Bitumenbahnen entstehen beim nachfolgenden Abkühlungsprozess unterschiedliche Schrumpfungen des Bitumens zwischen den Bahnen und den DeckLagen, die wiederum zu unzulässiger Faltenbildung führen.In addition, the floating of the two sheets creates bitumen layers of varying thickness between the sheets, and thus also bitumen top layers of varying thickness. The different thicknesses of bitumen sheets result in different shrinkages of the bitumen between the sheets and the top layers during the subsequent cooling process, which in turn leads to unacceptable wrinkling.
Der Erfindung liegt die Aufgabe zugrunde, ein isolierendes und dichtendes Baumaterial der eingangs genannten Gattung zu schaffen, dessen Herstellung nicht den einleitend genannten Schwierigkeiten ausgesetzt ist, insbesondere dessen Kosten erheblich gesenkt werden können. Die Erfindung als Lösung dieser Aufgabe zeichnet sich dadurch aus, daß die Glasfaserarmierung in Form eines Glasvlieses direkt mit der die Dampfsperre bildenden Folie verklebt wird. Vorzugsweise wird hierfür ein wasserlöslicher Kleber verwendet.The invention is based on the object of creating an insulating and sealing building material of the type mentioned at the beginning, the production of which is not subject to the difficulties mentioned at the beginning, and in particular the costs of which can be significantly reduced. The invention as a solution to this object is characterized in that the glass fiber reinforcement in the form of a glass fleece is glued directly to the film forming the vapor barrier. A water-soluble adhesive is preferably used for this purpose.
Nach der Herstellung des Verbundes zwischen dem als Dampfsperre dienenden Material und dem Glasvlies in hierfür geeigneten Maschinen wird durch einen Kaschierprozeß eine Strukturierungdie-After the bond between the material serving as a vapor barrier and the glass fleece has been created in suitable machines, a lamination process is used to structure the
ses Verbundes vorgenommen. Anschließend kann der Verbund DampfsperrenfoLie/GLasvLies mit hoher Geschwindigkeit durch das B i t u ■ tnenbad gefahren werden, um beide Seiten zu beschichten. Hierbei ist die Gefahr des VerLaufens 'zweier getrennt durch das Bitumenbad zu führender MateriaLbahnen nicht mehr gegeben, was die Kosten der HersteLLung erhebLich reduziert. DeLaminationen können nicht auftreten, da die aLs Dampfsperre verwendete FoLie und das GLasvLies direkt verkLebt sind. Der durch das Bitumenbad zu führende Verbund ist weitgehend temperaturunempfindLich, so daß das EinhaLten enger TemperaturtoLeranzen während des HersteLL-prozesses nicht notwendig ist. ZusätzLich ergibt sich eine ganz erhebLiche MateriaLersparnis . So kann beispieLsweise das gegenwärtig etwa 80 &rgr; dicke ALuminiummateria L auf etwa 20 &mgr; Wandstärke gesenkt werden. Die Menge des GLasvLieses kann ebenfaLLs von etwa 60 g/m auf 50 g/m verringert werden. Trotz Reduzierung des MateriaLeinsatzes wird eine Erhöhung der Zugfestigkeit des Verbundes erreicht.This composite is then tested. The composite of vapor barrier film/glass fleece can then be driven through the bitumen bath at high speed to coat both sides. This eliminates the risk of two separate strips of material running through the bitumen bath, which significantly reduces production costs. Delaminations cannot occur because the film used as a vapor barrier and the glass fleece are directly bonded. The composite to be fed through the bitumen bath is largely insensitive to temperature, so that it is not necessary to maintain tight temperature tolerances during the production process. This also results in considerable material savings. For example, the aluminum material, which is currently around 80 μm thick, can be reduced to around 20 μm wall thickness. The amount of glass fleece can also be reduced from around 60 g/m to 50 g/m. Despite the reduction in material usage, the tensile strength of the composite is increased.
In der Zeichnung ist der Ausschnitt einer Dachbahn im Querschnitt schematisch und erhebLich vergrößert dargesteLlt und nachstehend erLäutert.In the drawing, the section of a roofing membrane in cross-section is shown schematically and considerably enlarged and explained below.
Eine mit einem GLasvLies 1 kaschierte ALuminiumfoLie 2 ist beidseitig mit Bitumenschichten 3 und 4 versehen. Zwischen der ALuminiumfoLie 2 und dem GLasvLies 1 befindet sich eine Schicht 5 aus einem wasserLösLichen KLeber. Bei der HersteLLung wird der aus GLasvLies 1 und FoLie 2 gebiLdete Verbund nach dem getrennten Kaschiervorgang durch das Bitumenbad geführt, wobei das Bitumen die gesamte Verbundbahn aLLseitig umschLießt.An aluminum foil 2 laminated with a glass fleece 1 is provided on both sides with bitumen layers 3 and 4. Between the aluminum foil 2 and the glass fleece 1 there is a layer 5 made of a water-soluble adhesive. During production, the composite made of glass fleece 1 and foil 2 is passed through the bitumen bath after the separate lamination process, with the bitumen enclosing the entire composite sheet on all sides.
