Abstract
Description
In der DE 44 32 834.6 A1 werden Wege beschrieben, um die Emission von Radon in Gebäuden zu stoppen. Grundsätzlich handelt es sich dabei um Mate rialien, die immer eine Adsorptionsschicht auf Basis Aktivkohle enthalten und die Emissionsquelle vollständig abdecken. Wichtige Anwendungsformen sind Tapeten und Bodenbeläge. In allen Fällen ist die Adsorptionsschicht durch zwei Deckschichten geschützt; dabei kann die Außenschicht - die sichtbare Schicht - auf ihrer Rückseite die Adsorbenzien tragen, während die innere Ab deckung das Adsorbens beispielsweise gegen den Kleber (Tapete) schützt. Das Adsorbens (Aktivkohle) wird entweder als Kohleimprägnierung - vermahle ne Aktivkohle in Abmischung mit einer Binderdispersion - oder als Korn- bzw. Kugelkohle auf eine Haftmasse aufgebracht. Letztere ist die bevorzugte Aus führung, weil die freie Zugänglichkeit (keine, die Kohle umhüllende Polymer haut) zu einer besseren Kinetik führt. Der Mechanismus ist folgender: Radon wird in den Mikroporen genügend lange adsorbiert, um zu einem großen Teil in feste Tochternukleide zu zerfallen. Geschähe dies im menschlichen Körper, würde dies zu ortsfesten Strahlenquellen in unmittelbarer Nähe von Zellen füh ren, deren Schädigung zu Krebs führen kann.DE 44 32 834.6 A1 describes ways to reduce the emission of Stop radon in buildings. Basically, it is mate materials that always contain an adsorption layer based on activated carbon and completely cover the emission source. Important forms of application are Wallpaper and flooring. In all cases the adsorption layer is through two cover layers protected; the outer layer - the visible one Layer - on its back carry the adsorbents, while the inner ab cover protects the adsorbent, for example, against the adhesive (wallpaper). The adsorbent (activated carbon) is either ground as a carbon impregnation ne activated carbon mixed with a binder dispersion - or as grain or Ball charcoal applied to an adhesive. The latter is the preferred off leadership because of the free accessibility (no polymer enveloping the carbon skin) leads to better kinetics. The mechanism is as follows: radon is adsorbed long enough in the micropores to to disintegrate solid daughter nucleides. Would this happen in the human body, this would lead to fixed radiation sources in the immediate vicinity of cells those whose damage can lead to cancer.
Um die Verweilzeit in der Adsorptionsschicht zu erhöhen, wurden "Sperr schichten" vorgeschlagen. Sie verhindern zwar den Austritt von Radon nicht, verzögern aber den Durchtritt durch das Schutzmaterial und erhöhen die Chancen einer Adsorption. Derartige Verzögerungsschichten sollten eine ge wisse Wasserdampfdurchlässigkeit haben, damit der abgedeckte Gegenstand (Mauer, Boden) "atmen" kann. Einfachste Form einer solchen Schicht ist au ßenseitig ein Anstrich mit einer Dispersionsfarbe, es wurden auch flächen deckende, wasserdampfdurchlässige Haftstriche für die körnigen Adsorber als Verzögerungsschicht vorgeschlagen. In order to increase the residence time in the adsorption layer, "barriers layers. "They don't prevent radon from leaking, but delay the passage through the protective material and increase the Chances of adsorption. Such delay layers should have a ge know water vapor permeability, so the covered object (Wall, floor) can "breathe". The simplest form of such a layer is au Painting on the outside with a dispersion paint, there were also areas opaque, water vapor permeable adhesive coats for the granular adsorbers as Delay layer proposed.
Nun ist trotz seines hohen Molekulargewichts das Edelgas Radon verhältnis mäßig flüchtig, und es kann wünschenswert erscheinen, die "Löcher" zwischen den Aktivkohlekörnern bzw. -kügelchen zu vermeiden; sie können immerhin bis zu 0,5 mm betragen, was einem kleinen Durchtritt von Radon trotz Brownscher Bewegungen für möglich erscheinen läßt.Now, despite its high molecular weight, the noble gas ratio is radon moderately volatile, and it may seem desirable to put the "holes" between to avoid the activated carbon grains or spheres; after all, they can to be 0.5 mm, which is a small passage of radon despite Brownscher Movements seem possible.
Es war Ziel der vorliegenden Erfindung, eine wesentlich dichtere und kompak tere Adsorptionsschicht zu realisieren, die trotzdem wirtschaftlich sein sollte.The aim of the present invention was to make it much denser and more compact Realize adsorption layer, which should still be economical.
Die erfindungsgemäße Lösung besteht darin, daß auf ein Tapetenpapier oder sonstigen (textilen) Träger ein Flächengebilde aus Aktivkohle (Vlies, Gewirk, Gewebe) bzw. "Aktivkohlepapier" aufkaschiert und anschließend abgedeckt wird, um mögliche negative Effekte durch den Tapetenkleister zu vermeiden. Die Vorderseite kann mit einer Dispersionsfarbe angestrichen werden, um eine Verzögerungsschicht zu schaffen. Die Abdeckung der Hinterseite sollte mög lichst etwas elastische sein, um eine Steifheit (Sperrholzeffekt) zu vermeiden. Gut bewährt haben sich leichte Kreppapiere. Der Fachmann hat zahlreiche Möglichkeiten, das Laminat aus Vorderschicht, Adsorptionsschicht und hinterer Abdeckung herzustellen. So kann beispielsweise auf den der Adsorptions schicht zugekehrten Seiten von Vorderschicht und Abdeckung punktförmig eine Schmelzkleberpaste aufgedruckt werden und die drei Schichten können thermisch miteinander verbunden werden (Flachlaminiermaschine). Die Verzö gerungssicht kann durch einen Farbanstrich (Dispersionsfarbe) hergestellt wer den, wobei sich ein hoher Polymergehalt als vorteilhaft erwiesen hat. Eine an dere Möglichkeit ist, die der Adsorptionsschicht zugekehrte Seite der Vorder schicht vollüber mit einem thermoplastischen und wasserdampfdurchlässigen Kunststoff zu beschichten und diese "Verzögerungsschicht" als Kaschierkleber zu benutzen. The solution according to the invention is that on a wallpaper paper or other (textile) carrier a sheet of activated carbon (fleece, knitted fabric, Tissue) or "activated carbon paper" and then covered in order to avoid possible negative effects from the wallpaper paste. The front can be painted with an emulsion paint to make a Creating a delay layer. The back cover should be possible something elastic to avoid stiffness (plywood effect). Light crepe papers have proven their worth. The expert has numerous Possibilities, the laminate of front layer, adsorption layer and rear Manufacture cover. For example, the adsorption layer facing sides of front layer and cover point-like a hot melt adhesive paste can be printed on and the three layers can be thermally connected to each other (flat laminating machine). The delays view can be made by painting (emulsion paint) the, whereby a high polymer content has proven to be advantageous. One on the other option is the side of the front facing the adsorption layer layer completely with a thermoplastic and water vapor permeable Coating plastic and this "retardation layer" as a lamination adhesive to use.
Die Aktivkohleschicht sollte sehr kompakt sein und 20-250 g, vorzugsweise 100-220 g pro m² schwer sein. Bevorzugt werden Aktivkohlen mit sehr engen Mikroporen (2-10 °A, vorzugsweise 3-6 °A), in denen Radon relativ gut adsor biert wird. Die innere Oberfläche sollte 800 m²/g, bevorzugterweise 900 m²/g, betragen.The activated carbon layer should be very compact and 20-250 g, preferably Weigh 100-220 g per m². Activated carbons with very narrow Micropores (2-10 ° A, preferably 3-6 ° A), in which radon adsorbed relatively well beers. The inner surface should be 800 m² / g, preferably 900 m² / g, be.
Dem Fachmann stehen heute Vliese, Gewirke, Gewebe und Papiere aus Aktiv kohle zur Verfügung, die aus Mikrofasern verschiedener Rohstoffbasis herge stellt werden. Sie haben eine enorme Zugänglichkeit und eine ganz ausge zeichnete Kinetik.Nonwovens, knitted fabrics, woven fabrics and papers made from active are available to the expert today Coal available from microfibers of various raw material bases be put. You have tremendous accessibility and quite a lot plotted kinetics.
In ähnlicher Weise lassen sich Bodenbeläge mit Sperrwirkung gegenüber Ra don herstellen. So hat sich eine zwischen Folien eingeschweißte Bahn aus Ak tivkohle-Vlies (ca. 210 g/m²) unter Holzparkett bewährt. Bei Teppichböden kann die Adsorptionsschicht direkt auf eine Rückenbeschichtung aufkaschiert werden; sie muß an der Unterseite zum Schutz gegen Abrieb abgedeckt sein. Grundsätzlich sind alle bei der Tapete beschriebenen Aktivkohle-Flächengebil de geeignet.In a similar way, flooring with a barrier effect against Ra don create. So there was a sheet of Ak welded between foils Tivkohle-Vlies (approx. 210 g / m²) proven under wooden parquet. For carpets the adsorption layer can be laminated directly onto a back coating will; it must be covered on the underside to protect against abrasion. Basically, all activated carbon surface areas described in the wallpaper are de suitable.
Eine Papiertapete wurde auf ihrer Rückseite mit einer Schmelzkleberpaste der Fa. Atochem, Bonn, mit einer 11 mesh Schablone bedruckt und getrocknet. Auflage 26 g/m². Andererseits wurde eine etwas wasserfeste Kreppbahn, Flä chengewicht ungefähr 50 g/m², mit der gleichen Paste bedruckt und getrock net. Gesamtgewicht 71 g/m². Schließlich wurden die beiden Papierbahnen auf ein Aktivkohlevlies der Fa. Carbon Cloth Ltd. (210 g/m² schwer und aus Mikro fasern hergestellt) thermisch aufkaschiert (165 °C, Laminator der Fa. Kanne gießer) und die Vorderseite mit einer Dispersionsfarbe abgedeckt (Auflage 42 g/m²). Die Messung des Radondurchtritts geschah in einer Meßkammer, die durch das zu untersuchende Produkt in zwei Teile getrennt wird, wobei sich auf einer Seite Radon befindet. Man mißt die Radioaktivität auf der "Leerseite" bis Eintritt eines Gleichgewichts. Der Radondurchbruch war etwa dreißigmal geringer als beim gleichen Schichtaufbau, jedoch mit einem Polyestervlies statt des Aktivkohlevlieses.A paper wallpaper was covered with a hot melt paste on the back Atochem, Bonn, printed with an 11 mesh stencil and dried. Edition of 26 g / m². On the other hand, a somewhat waterproof crepe track, Flä weight approx. 50 g / m², printed with the same paste and dried net. Total weight 71 g / m². Finally, the two paper webs were up an activated carbon fleece from Carbon Cloth Ltd. (210 g / m² heavy and made of micro fibers) thermally laminated (165 ° C, laminator from Kanne pourer) and the front is covered with an emulsion paint (edition 42 g / m²). The radon penetration was measured in a measuring chamber is separated into two parts by the product to be examined, whereby Radon is located on one side. You measure the radioactivity on the "blank page" until equilibrium occurs. The radon breakthrough was about thirty times less than with the same layer structure, but instead with a polyester fleece of the activated carbon fleece.
Eine Papiertapete wurde auf der Rückseite mit einem weichen, wasserdampf durchlässigen Polyurethan mit einem Erweichungspunkt von ca. 145°C be schichtet. Auflage 30 g/m². Diese Beschichtung erfüllte gleichzeitig die Rolle einer Verzögerungsschicht wie die eines Kaschierklebers. Als Adsorptions schicht wurde ein Aktivkohlepapier (50 g/m²) der Fa. Toybo eingesetzt; die hin tere Abdeckung war die gleiche wie im Beispiel 1. Der Radondurchbruch war um ca. 30% höher als beim Material des Beispiels 1, was jedoch immer noch ein sehr gutes Ergebnis ist.A paper wallpaper was made on the back with a soft, water vapor permeable polyurethane with a softening point of approx. 145 ° C layers. Edition of 30 g / m². This coating also played the role a retardation layer like that of a laminating adhesive. As adsorption an activated carbon paper (50 g / m 2) from Toybo was used; the down The outer coverage was the same as in example 1. The radon breakthrough was about 30% higher than the material of Example 1, but still is a very good result.
