Description
Dampfdiffiisionsoffene, wasserdichte und reflektierende Folie Vapor-open, waterproof and reflective film
Die Erfindung betrifft eine dampfdiffusionsoffene, wasserdichte und reflektierende Folie zur Verwendung in Dampfsperr-, Abdichtungs- und Dämmbahnen in und an Gebäuden, insbesondere zur Verwendung in und mit Wärmedämmungen.The invention relates to a vapor diffusion-open, waterproof and reflective film for use in vapor barrier, waterproofing and insulating membranes in and on buildings, in particular for use in and with thermal insulation.
Dampfsperr-, Abdichtungs- und Dämmbahnen werden üblicherweise zur raumseitigen Abdichtung von Dachkonstruktionen eingesetzt, wobei ein Abtransport von Feuchte, insbesondere in Form von Wasserdampf, von der Raumseite zur Dachseite erzielt werden soll, aber ein Eindringen von Feuchte von der Dachseite möglichst gehemmt werden soll. Dampfsperr-, Abdichtungs- und Dämmbahnen schützen die Wärmedämmung vor Durchfeuchtung und gewährleisten dadurch deren Funktionsfahigkeit. Feuchte- und Wärmetransport durch Konvektiόn werden verhindert.Vapor barrier, waterproofing and insulating membranes are usually used for room-side sealing of roof structures, with a removal of moisture, especially in the form of water vapor, should be achieved from the room side to the roof side, but moisture from the roof side should be inhibited as possible. Vapor barrier, waterproofing and insulating membranes protect the thermal insulation against moisture penetration and thus ensure their functionality. Moisture and heat transfer by convection are prevented.
Darüber hinaus besteht häufig noch die Anforderung, Wärmestrahlung entweder in einem Raum zu halten oder nicht ins Rauminnere gelangen zu lassen. Dies kann durch eine reflektierende Schicht erreicht werden. Metalle wie Aluminium weisen einen hohen Reflexionsgrad auf, sind aber wasserdampfsperrend.In addition, there is often still the requirement to keep heat radiation either in a room or not to get into the room interior. This can be achieved by a reflective layer. Metals such as aluminum have a high reflectance, but are water vapor barrier.
Eine Kombination aus einer dampfdiffusionsoffenen, wasserdichten sowie wärmereflektierenden Abdichtungsbahn ist aus der deutschen Gebrauchsmusterschrift DE 20 2004 007 543 Ul bekannt. Die wärmereflektierende Schicht wird in einer Ausftihrungsform mittels einer Metallbedampfung auf eine Folie aufgebracht. Um die gewünschteA combination of a vapor diffusion open, waterproof and heat-reflecting waterproofing membrane is known from German Utility Model DE 20 2004 007 543 Ul. The heat-reflecting layer is applied to a foil by means of metal vapor deposition in an embodiment. To the desired
Dampfdiffusion zu gewährleisten, wird diese Folie einer Prägung und Lochung unterzogen.To ensure vapor diffusion, this film is subjected to embossing and perforation.
Dies bedeutet nicht nur einen erheblichen Mehraufwand bei der Herstellung, sondern die Poren stellen Ausgangspunkte für mögliche Fehlstellen, wie Risse dar, die die Funktion, insbesondere die Konvektion beinträchtigen können.This not only means a considerable extra effort in the production, but the pores are starting points for possible defects, such as cracks, which can affect the function, in particular the convection.
Die Erfindung stellt sich die Aufgabe eine verbesserte Dampfsperr-, Abdichtungs- und Dämmbahn in Form einer Folie zur Verfügung zu stellen.
Die erfindungsgeniäße dampfdiffusionsoffene, wasserdichte und reflektierende Folie besteht zumindest aus zwei Schichten, wobei eine erste Schicht aus einer dampfdiffusionsoffenen und wasserdichten Trägerschicht und eine zweite Schicht aus einer reflektierenden Schicht aus einem Metall oder Metalloxid besteht und dadurch gekennzeichnet ist, dass die reflektierende Schicht unterbrechungsfrei direkt auf der Trägerschicht aufgebracht ist.The object of the invention is to provide an improved vapor barrier, sealing and insulating sheet in the form of a film. The erfindungsgeniäße vapor diffusion-open, waterproof and reflective film consists of at least two layers, wherein a first layer of a vapor diffusion-open and waterproof backing layer and a second layer of a reflective layer of a metal or metal oxide and is characterized in that the reflective layer without interruption directly on the carrier layer is applied.
Überraschenderweise hat sich gezeigt, dass durch eine gezielte Aufbringung einer reflektierenden Schicht auf einer wasserdampfdurchlässigen und wasserdichten Trägerschicht eine Folie mit einem hohen Reflexionsgrad sowie eine hohe Wasserdampfdurchlässigkeit erreicht werden kann.Surprisingly, it has been found that a film with a high degree of reflection and a high water vapor permeability can be achieved by a specific application of a reflective layer on a water vapor-permeable and waterproof carrier layer.
Als Trägerschicht kann jedes bekannte dampfdiffusionsoffene, d.h. wasserdampfdurchlässige sowie wasserdichte Material verwendet werden. Derartige Materialien sind z.B. Polyamide, Polyester, Polyurethane, Ethylenvinylacetate, Polyvinylchloride, thermoplastische Elastomere.As carrier layer, any known vapor diffusion open, i. water vapor permeable and waterproof material can be used. Such materials are e.g. Polyamides, polyesters, polyurethanes, ethylene vinyl acetates, polyvinyl chlorides, thermoplastic elastomers.
Die Wasserdampfdurchlässigkeit der Trägerschicht kann von 5 g/m2d bis 5000 g/m2d betragen. Der Reflexionsgrad der Trägerschicht liegt im unteren Bereich von kleiner 50 %.The water vapor permeability of the carrier layer can be from 5 g / m 2 d to 5000 g / m 2 d. The reflectance of the carrier layer is in the lower range of less than 50%.
Auf diese Trägerschicht wird die reflektierende Schicht, welche im Fall von Metallschichten vorzugsweise aus Aluminium oder im Fall von Metalloxiden vorzugsweise aus Aluminiumoxid besteht, aufgebracht. Die Aufbringung erfolgt insbesondere durch Aufdampfen nach einem herkömmlichen Verfahren.The reflective layer, which in the case of metal layers preferably consists of aluminum or, in the case of metal oxides, preferably of aluminum oxide, is applied to this carrier layer. The application is carried out in particular by vapor deposition according to a conventional method.
Die reflektierende Schicht wird in einer derartigen Stärke aufgebracht, dass eine optische Dichte von 0,5 bis 2,5, vorzugsweise von 1-1,5 erreicht wird. Die Messung der optischenThe reflective layer is applied in a thickness such that an optical density of 0.5 to 2.5, preferably 1-1.5, is achieved. The measurement of the optical
Dichte erfolgt mittels Dichtemeßgeräten, z.B. Theimer DDM3 bzw. X-Rite bei durchsichtigen Prüflingen oder mit dem Meßgerät Nagy SD 510 für undurchsichtige PrüflingeDensity is carried out by density meters, e.g. Theimer DDM3 or X-Rite for transparent specimens or with the Nagy SD 510 gauge for opaque specimens
Das Verhältnis der Wasserdampfdurchlässigkeit in Prozent einer erfmdungsgemäßen Folie zur Wasserdampfdurchlässigkeit einer unbeschichteten Trägerschicht beträgt von 70 % bis 95 %.
Die Wasserdampfdurchlässigkeit kann nach z.B. nach DIN 52615: „Bestimmung derThe ratio of the water vapor permeability in percent of a film according to the invention for the water vapor permeability of an uncoated carrier layer is from 70% to 95%. The water vapor permeability can according to eg according to DIN 52615: "Determination of
Wasserdampfdurchlässigkeit von Bau- und Dämmstoffen. November 1987" ermittelt werden.Water vapor permeability of construction and insulation materials. November 1987 ".
Der Reflexionsgrad einer erfmdungsgemäßen Folie beträgt größer gleich 70 %, vorzugsweise von 70 % bis 87 %. Der Reflektionsgrad in Prozent gibt das Verhältnis von zurückgeworfener zu eingestrahlter Energie an.The reflectance of a film according to the invention is greater than or equal to 70%, preferably from 70% to 87%. The degree of reflection in percent indicates the ratio of reflected to irradiated energy.
Es war überraschend, dass eine Metallschicht mit einem derart hohen Reflexionsgrad dennoch noch so wasserdampfdurchlässig ist, dass die Wasserdampfdurchlässigkeit einer erfindungsgemäßen Folie einen technisch sinnvollen Bereich umfasst.It was surprising that a metal layer with such a high degree of reflection is still so permeable to water vapor that the water vapor permeability of a film according to the invention comprises a technically meaningful range.
Die Fig. 1 zeigt den Verlauf des Reflexionsgrades R und der Wasserdampfdurchlässigkeit WDD in Abhängigkeit von der optischen Dichte OD einer erfindungsgemäßen Folie. Die Trägerschicht ist eine 40 μm starke Polyamid-Folie, die mit Aluminiumoxid in unterschiedlicher optischer Dichte bedampft ist.FIG. 1 shows the course of the reflectance R and the water vapor permeability WDD as a function of the optical density OD of a film according to the invention. The carrier layer is a 40 micron thick polyamide film, which is vapor-deposited with aluminum oxide in different optical density.
Der Reflexionsgrad R steigt hier mit zunehmender optischer Dichte OD von etwa 20% der unbeschichteten Trägerschicht auf etwa 95% gemäß der Kurve (■-■-■) an, wobei eine Abnahme der Wasserdampfdurchlässigkeit WDD, dargestellt durch die Kurve (A-A-A), erfolgt.The reflectance R increases here with increasing optical density OD of about 20% of the uncoated support layer to about 95% according to the curve (■ - ■ - ■), wherein a decrease in the water vapor permeability WDD represented by the curve (A-A-A) occurs.
Die erfindungsgemäße Folie kann zusätzlich mit weiteren Verstärkungs- und/oder Schutzschichten kombiniert werden. Dazu eignen sich insbesondere Vliese, Gewebe, Gelege, Schäume, Lacke und andere funktionelle Schutzschichten.The film according to the invention can additionally be combined with further reinforcing and / or protective layers. In particular, nonwovens, fabrics, scrims, foams, lacquers and other functional protective layers are suitable for this purpose.
Die erfindungsgemäße Folie ist vorzugsweise als Dämmbahn geeignet. Diese Dämmbahn kann aus einer oder mehreren Lagen der erfindungsgemäßen Folien bestehen.The film according to the invention is preferably suitable as an insulation sheet. This insulation sheet may consist of one or more layers of the films of the invention.
Die Dämmbahn ist besonders geeignet zur Verwendung in Kühlcontainern, in Wärmebehältern, in Transportbehältern, insbesondere für die Schifffahrts-, Automobil-, Luft- oder Raumfahrtindustrie, in Funktionstextilien und in Schuhwerken.
