Description

Die Erfindung betrifft eine Barriere für den Einsatz zur Behinderung bzw. Vermeidung von Luftkonvektion in Bauteile und 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 to obstruct or avoid air convection in Components and emission of pollutants from components, from neighboring rooms, the ground or groundwater in Rooms in buildings, for use in new buildings, renovation of old buildings and during renovations to Protection of components emerging from freshly treated components 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 known so far and is also widely used Measures to be taken on buildings that prevent diffusion of water vapor to reduce the respective components especially before those caused by condensation Protect moisture damage.

Probleme treten aber auch durch Luftströmungen auf, die einen sehr hohen Anteil an Feuchtigkeit in das ungeschützte Bauteil einbringen können, der sogar höher als die Feuchtigkeitsmenge, die durch Wasserdampfdiffusion eindringt, sein kann.But problems also arise from air currents, which has a very high amount of moisture in it unprotected component can even bring higher than the amount of moisture caused by water vapor diffusion penetrates, can be.

Ein anderes Problem, daR 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.Another problem is that with previously known designs not considered or only insufficiently considered is is the ingress of pollutants, in particular gaseous penetration into rooms and damage to health being able to lead. Such pollutants can e.g. in wood preservatives used, others Paint materials are included or monomers Insulation boards made of plastics that are in unprotected Can diffuse rooms. Likewise, organic Solvents from adjacent work rooms diffuse into unprotected lounges. The the same applies to facade treatment with water repellents and consolidation. You can also Convective pollutants (e.g. radon) from the underground or penetrate into spaces by diffusion.

Ausgehend hiervon, ist es Aufgabe der Erfindung, eine Barriere zu schaffen, die in der Lage ist, unter verschiedenen Bedingungen, variabel im Einsatz, einen Schutz des Inneren von Räumen gegen den negativen Einfluß der Luftkonvektion und gegen eventuell auftretende Schadstoffemissionen zu sichern.Based on this, it is an object of the invention to provide a To create barrier that is able to differentiate among Conditions, variable in use, one Protection of the interior of rooms against the negative Influence of air convection and against possibly occurring Secure pollutant emissions.

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 in the claim 1 mentioned features solved. Training and embodiments of the invention result when using the in the subordinate claims mentioned features.

Die erfindungsgemäß zu verwendende Barriere wird bevorzugt in Form einer Folie, die auch auf einem Trägermaterial aufgebracht sein kann, ausgebildet. Das hierfür eingesetzte Material, bevorzugt ein Polyamid, soll aber auch eine gewisse Durchlässigkeit für Wasserdampf haben.The barrier to be used according to the invention is preferred in the form of a film, which is also on a carrier material can be applied, trained. The material used for this, preferably a polyamide, but should also have a certain permeability to water vapor to have.

Dies führt dazu, daß die Austrocknung von Bauteilen insbesondere beim Neubau oder unmittelbar nach Sanierung bzw. Umbau ermöglicht wird.This leads to the drying out of components especially when building a new building or immediately after renovation or conversion is made possible.

Mit dem Einsatz der erfindungsgemäßen Barriere kann neben dem Schutz der Bauteile vor der durch Luftkonvektion eintragbaren Feuchtigkeit auch günstig Einfluß auf das Wohlbefinden in entsprechend geschützten Räumen genommen werden.With the use of the barrier according to the invention in addition to protecting the components from air convection Enterable moisture also has a favorable influence on well-being in appropriately protected Rooms.

Die Erfindung kann neben den bereits bei den Nachteilen des Standes der Technik genannten Einsatzzwecken auch bei Dächern oder Holzständerkonstruktionen verwendet werden und dort besonders dem negativen Einfluß der Luftkonvektion und übermäßiger Dampfdiffusion entgegenwirken.In addition to the disadvantages, the invention can already uses mentioned in the prior art also used for roofs or wooden frame constructions and especially the negative influence air convection and excessive vapor diffusion counteract.

Als Material für die Barriere, das die gewünschten Eigenschaften aufweist, kann beispielsweise ein Polyamid 6, ein Polyamid 4 oder Polyamid 3 oder 12 sowie Mischpolyamide, wie sie insbesondere aus Biederbick, K.: "Kunststoffe - kurz und bündig", Vogel-Verlag, Würzburg bekannt sind, verwendet werden. Diese Polyamide werden als Folien eingesetzt und weisen die geforderten Eigenschaften in bezug auf den Wasserdampfdiffusionswiderstand, 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 that the desired Has properties, for example a polyamide 6, a polyamide 4 or polyamide 3 or 12 as well Mixed polyamides, such as those from Biederbick, K .: "Plastics - in a nutshell", Vogel Verlag, Würzburg are known to be used. This Polyamides are used as films and have the required properties in relation to water vapor diffusion resistance, Protection against air convection and inherent emission of pollutants. Furthermore they have the necessary in use in buildings Strengths so that they without additional Effort can be used.

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, you can also use suitable substrates be applied. The carrier materials have preferably a low water vapor diffusion resistance on and the required properties of the barrier according to the invention are essentially of 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, Foils from synthetic fiber cobwebs or Building boards are 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 one-sided on the carrier material, but also in special Cases sandwiched between two layers of substrate be included. In the latter case the coating material effective from both sides protected against mechanical attack and can the desired properties over a long period of time to guarantee. There can also be several Layered structures can be used one on top of 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 can be applied to the side on which there is little or no protection against mechanical Influencing is required. The attachment the barrier according to the invention can in this Case so that the protective backing material to the room facing or facing away from the room Side shows. This is especially true with building boards be the case for the interior.

Es kann auch günstig sein, die Polyamidfolie einseitig zumindest teilweise mit einem Haftvermittler zu 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.It can also be favorable to have the polyamide film on one side at least partially with an adhesion promoter provided so that attachment to walls or Plates can be done in a simple way without using additional fasteners need to be the polyamide film punctually and there are opportunities for that 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 ribbon-like design of the polyamide film is special for use in sealing joint areas cheap, with such a band-shaped Polyamide film can be coated with an adhesion promoter can. Such a film strip can run along a joint be arranged and this particularly critical area seal.

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

Dabei wird die erfindungsgemäße 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 according to the invention is formed solely from a film made of polyamide 6. The film thickness is preferably in a range from 10 to 500 μm, very particularly advantageously with a thickness of 50 μm. Experiments with a film thickness of 50 µm have, under measurement conditions according to DIN 52650, a water vapor diffusion resistance (s d value) of 4.5 m in the dry area with an average relative humidity of about 30% and in the wet area with an average relative humidity of approx. 70% give a water vapor diffusion resistance (s d value) of 0.5 m of a diffusion-equivalent air layer thickness.
