Description

Die Erfindung betrifft eine Barriere für den Einsatz zur Behinderung bzw. Vermeidung von Emission von Schadstoffen aus Bauteilen, aus Nachbarräumen, dem Erdreich oder Grundwasser in Räume von Gebäuden, zum Einsatz beim Neubau, der Sanierung von Altbauten und während Umbaumaßnahmen zum Schutz von aus frisch behandelten Bauteilen austretenden Lösungsmitteln.The invention relates to a barrier for use for obstructing or avoiding emission of pollutants from components, from neighboring areas, the soil or groundwater in rooms of buildings, for use in new construction, the renovation of old buildings and during conversion to protect from freshly treated Components leaking solvents.

Es ist bisher bekannt und auch weit verbreitet üblich Maßnahmen an Gebäuden vorzusehen, die die Diffusion von Wasserdampf reduzieren, um die jeweiligen Bauteile insbesondere vor den durch Tauwasseranfall hervorrufbaren Feuchteschäden zu schützen.It is hitherto known and widely used to provide measures on buildings that reduce the diffusion of water vapor in order to protect the respective components, in particular from the moisture damage caused by condensation.

Das Problem, daß bei bisher bekannten Ausführungen nicht oder nur unzulänglich berücksichtigt wird, ist das Eindringen von Schadstoffen, die insbesondere gasförmig in Räume eindringen und zu Gesundheitsschäden führen können. Solche Schadstoffe können z.B. in verwendeten Holzschutzmitteln, anderen Anstrichstoffen enthalten sein oder auch Monomere aus Dämmplatten aus Kunststoffen sein, die in ungeschützte Räume eindiffundieren können. Ebenso können organische Lösungsmittel aus angrenzenden Arbeitsräumen in ungeschützte Aufenthaltsräume eindiffundieren. Das gleiche gilt für eine Fassadenbehandlung mit Hydrophobierungsmitteln und Festigern. Außerdem können Schadstoffe (z.B. Radon) aus dem Untergrund konvektiv oder durch Diffusion in Räume eindringen.The problem that is not or only insufficiently taken into account in previously known embodiments, is the ingress of pollutants, which in particular penetrate gaseous into rooms and can lead to damage to health. Such pollutants can e.g. used in wood preservatives used, other paints or be monomers made of plastic insulating boards that can diffuse into unprotected spaces. Likewise, organic solvents from adjacent workrooms can diffuse into unprotected lounges. The same applies to a facade treatment with water repellents and fixatives. In addition, pollutants (e.g., radon) from the subsurface may convectively or by diffusion into spaces.

So ist aus US-A-3 445 322 ein Wasserbarrierelaminat bekannt, bei dem unter anderem eine wasserundurchlässige Membran verwendet wird. Eine solche Membran kann aus unterschiedlichen Kunststoffen bestehen und gegebenenfalls auch perforiert sein.That's how it is U.S.-A-3,445,322 a water barrier laminate is known in which, inter alia, a waterproof membrane is used. Such a membrane may consist of different plastics and optionally also be perforated.

Die US-A-4 878 421 offenbart die Verwendung einer wasserdampfdurchlässigen Polyäthylenfolie als raumseitig angeordnete Barriere zum Schutz des Inneren von Räumen und Gebäuden vor dem Eindringen eventuell auftretender Schadstoffemissionen.The U.S. Patent 4,878,421 discloses the use of a water vapor permeable polyethylene as a barrier arranged on the room side to protect the interior of rooms and buildings from the penetration of any pollutant emissions that may occur.

Ausgehend hiervon, ist es Aufgabe der Erfindung, eine Barriere zu verbessern, die in der Lage ist, unter verschiedenen Bedingungen, variabel im Einsatz, einen Schutz des Inneren von Räumen gegen eventuell auftretende Schadstoffemissionen zu sichern.Proceeding from this, it is an object of the invention to improve a barrier, which is able to secure under different conditions, variable in use, a protection of the interior of rooms against any pollutant emissions occurring.

Erfindungsgemäß wird diese Aufgabe durch die im Patentanspruch 1 genannten Merkmale gelöst. Weiterbildungen und Ausgestaltungen der Erfindung ergeben sich bei Verwendung der in den untergeordneten Ansprüchen genannten Merkmale.According to the invention this object is achieved by the features mentioned in claim 1. Further developments and embodiments of the invention will become apparent when using the features mentioned in the subordinate claims.

Die Erfindung kann neben den bereits bei den Nachteilen des Standes der Technik genannten Einsatzzwecken auch bei Dächern oder Holzständerkonstruktionen verwendet werden.The invention can be used in addition to the already mentioned in the disadvantages of the prior art uses also in roofs or wooden stud constructions.

Als Material für die Barriere, das die gewünschten Eigenschaften aufweist, werden ein Polyamid 6, ein Polyamid 4 oder Polyamid 3 sowie Mischpolyamide, wie sie insbesondere aus Biederbick, K.: "Kunststoffe - kurz und bündig", Vogel-Verlag, Würzburg bekannt sind, verwendet. Diese Polyamide werden als Folien eingesetzt und weisen die geforderten Eigenschaften in bezug auf den Schutz gegen Luftkonvektion und Schadstoffemission immanent auf. Außerdem verfügen sie über die im Einsatz in Gebäuden erforderlichen Festigkeiten, so daß sie ohne zusätzlichen Aufwand einsetzbar sind.As a material for the barrier, which has the desired properties, a polyamide 6, a polyamide 4 or polyamide 3 and Mischpolyamide, as they are known in particular from Biederbick, K .: "Plastics - short and to the point", Vogel-Verlag, Würzburg , used. These polyamides are used as films and have the required properties with respect to the protection against air convection and pollutant emissions immanent. In addition, they have the required strength in use in buildings, so that they can be used without additional effort.

Sie können jedoch auch auf geeignete Trägermaterialien aufgebracht werden. Die Trägermaterialien weisen dabei bevorzugt einen geringen Wasserdampfdiffusionswiderstand auf und die geforderten Eigenschaften der erfindungsgemäßen Barriere werden im wesentlichen von der Beschichtung bewirkt.However, they can also be applied to suitable carrier materials. The support materials preferably have a low water vapor diffusion resistance and the required properties of the barrier according to the invention are essentially caused by the coating.

Als Materialien für den bzw. die Träger können beispielsweise, Folien aus Kunstfaserspinngeweben oder Bauplatten für den Innenausbau eingesetzt werden.As materials for the carrier (s), for example, films made of synthetic fiber spun fabrics or building boards can be used for interior work.

Das Barrierematerial für die Folie kann dabei einseitig auf das Trägermaterial, aber auch in besonderen Fällen zwischen zwei Trägermaterialschichten sandwichartig aufgenommen werden. Im letzten Fall wird das Beschichtungsmaterial von beiden Seiten wirksam gegen mechanischen Angriff geschützt und kann dadurch über einen langen Zeitraum die gewünschten Eigenschaften garantieren. Es können auch mehrere solcher Schichtaufbauten übereinandergelegt eingesetzt werden.The barrier material for the film can be sandwiched on one side on the carrier material, but also in special cases between two layers of carrier material. In the latter case, the coating material is effectively protected against mechanical attack from both sides and can thus guarantee the desired properties over a long period of time. It is also possible to use several such layer structures one above the other.

Im Falle der einseitigen Beschichtung des Trägermaterials kann diese auf der Seite aufgebracht werden, auf der kein oder nur ein geringer Schutz gegen mechanische Beeinflussung erforderlich ist. Die Anbringung der erfindungsgemäßen Barriere kann in diesem Fall so erfolgen, daß das schützende Trägermaterial zur dem Raum zugewandten oder zur dem Raum abgewandten Seite zeigt. Dies wird insbesondere bei Bauplatten für den Innenausbau der Fall sein.In the case of one-sided coating of the carrier material, this can be applied to the side on which little or no protection against mechanical influence is required. The attachment of the barrier according to the invention can in this case be such that the protective carrier material faces the room or facing away from the room side. This will be the case in particular for structural panels for interior work.

Die Polyamidfolie ist einseitig zumindest teilweise mit einem Haftvermittler versehen, so daß eine Befestigung an Wänden bzw. Platten auf einfache Art und Weise erfolgen kann, ohne daß zusätzliche Befestigungsmittel verwendet werden müssen, die eventuell die Polyamidfolie punktuell verletzen und dort Möglichkeiten für das Eindringen von Schadstoffen entstehen.The polyamide film is on one side at least partially provided with a primer, so that attachment to walls or plates can be done in a simple manner without additional fasteners must be used, which may violate the polyamide selectively and there opportunities for the penetration of pollutants arise.

Ein bandförmige Ausbildung der Polyamidfolie ist besonders für den Einsatz zur Abdichtung von Fugenbereichen günstig, wobei auch eine solche bandförmige Polyamidfolie mit Haftvermittler beschichtet sein kann. Ein solches Folienband kann entlang einer Fuge angeordnet sein und diesen besonders kritischen Bereich abdichten.A band-shaped design of the polyamide film is particularly favorable for use in sealing joint areas, wherein such a band-shaped polyamide film may be coated with adhesion promoter. Such a film strip can be arranged along a joint and seal this particularly critical area.

Nachfolgend soll die Erfindung beispielhaft erläutert werden.The invention will be explained by way of example below.

Dabei wird die Barriere allein aus einer Folie, die aus Polyamid 6 besteht, gebildet. Die Foliendicke liegt bevorzugt in einem Bereich von 10 bis 500 µm, ganz besonders günstig bei einer Dicke von 50 µm. Versuche mit einer Foliendicke von 50 µm haben unter Meßbedingungen nach DIN 52650 im trockenen Bereich bei einer mittleren relativen Feuchte von etwa 30 % einen Wasserdampfdiffusionswiderstand (sd-Wert) von 4,5 m und im feuchten Bereich bei einer mittleren relativen Feuchte von ca. 70 % einen Wasserdampfdiffusionswiderstand (sd-Wert) von 0,5 m einer diffusionsäquivalenten Luftschichtdicke ergeben.The barrier is formed solely from a film consisting of polyamide 6. The film thickness is preferably in a range of 10 to 500 microns, most preferably at a thickness of 50 microns. tries with a film thickness of 50 .mu.m under measuring conditions according to DIN 52650 in the dry range at a mean relative humidity of about 30%, a water vapor diffusion resistance (s d value) of 4.5 m and in the wet region at an average relative humidity of about 70 % yield a water vapor diffusion resistance (s d value) of 0.5 m of a diffusion-equivalent air layer thickness.
