Abstract
Description
Die Erfindung kann dort angewendet werden, wo gasförmige Schadstoffe in einem nahezu geschlossenen Raum sich anreichern können und die hauptsächlich aus Ausgasungen von Baustoffen, Möbeln, Bodenbelägen, Tapeten, Klebstoffen, Lacken, Dichtungsmaterialien, Kunststoffen oder Kraftfahrzeugen stammen.The invention can be used where gaseous pollutants in a near can accumulate in the enclosed space and which mainly result from outgassing of Building materials, furniture, floor coverings, wallpapers, adhesives, paints, sealing materials, Plastics or motor vehicles.
Aber auch Krankenhäuser, Tiefgaragen oder Straßentunnel können einbezogen werden.Hospitals, underground car parks or road tunnels can also be included.
Schlechte Innenraumluft ist die Quelle vieler chronischer Leiden, da die Mitteleuropäer 90% ihrer Zeit in umschlossenen Räumen verbringen. Krankenhäuser zählen nicht zu den Innenräumen, da durch den Einsatz von Desinfektionsmitteln eine Sonderbelastung auftritt.Poor indoor air is the source of many chronic ailments, as the Central Europeans 90% spend their time in enclosed spaces. Hospitals are not among them Indoors, because disinfectants cause a special load.
9 Millionen Deutsche arbeiten in Büros, davon 3 Millionen unter den Bedingungen einer Klimaanlage. Bedingt durch Emissionen aus Baustoffen, Inventargegenständen, Teppichen, Bodenbelägen, Farben, Lacke, Kosmetikartikel usw. tritt verstärkt das "Sick-Building-Syndrom" (Gebäudekrankheit) auf und verursacht durch die Vielzahl chemischer Verbindungen in kleinen Konzentrationen unspezifische Krankheitssymptome. Die Beschwerdemuster sind sehr unterschiedlich und diffus und verursachen heute einen hohen Krankenstand. Es ist folglich unumgänglich, ein am Vorsorgeprinzip orientierenden Gesundheitsschutz dagegen zu setzen. Schädliche Einflüsse und Emissionen durch Baustoffe und Inneneinrichtungen müssen vermieden werden. Durch Wärmeisoliermaßnahmen ist eine neue Wohnatmosphäre entstanden, die noch unterstützt durch unzureichendes Lüftungsverhalten, zu einem ungesunden Wohnklima geführt hat. Inzwischen ist die Qualität der Innenraumluft deutlich schlechter als die Außenluft. Erschwerend kommt noch hinzu, das im Gegensatz zum Boden, dem Wasser und der Außenluft die Innenraumluft noch kein Schutzgut ist, obwohl der Mensch zum Leben täglich ca. 20 m3 Luft benötigt und Innenräume ein wesentlicher Teil der menschlichen Umwelt sind. 9 million Germans work in offices, 3 million of them under the conditions of an air conditioning system. Due to emissions from building materials, inventory items, carpets, floor coverings, paints, varnishes, cosmetics, etc., the "sick building syndrome" (building disease) occurs increasingly and causes unspecific disease symptoms due to the large number of chemical compounds in small concentrations. The complaint patterns are very different and diffuse and cause a high level of sickness today. It is therefore imperative to set health protection against this, based on the precautionary principle. Harmful influences and emissions from building materials and interior fittings must be avoided. Thermal insulation measures have created a new living atmosphere, which, supported by inadequate ventilation, has led to an unhealthy living environment. In the meantime, the quality of the indoor air is significantly worse than the outside air. To make matters worse, in contrast to the soil, water and outside air, indoor air is not yet a protected good, although people need about 20 m 3 of air every day to live and indoor spaces are an essential part of the human environment.
Das Spektrum der chemischen Verbindungen umfaßt in deutschen Haushalten hauptsächlich 40
potentiell schädliche Substanzen und die wichtigsten Verbindungsklassen sind (Erhebung des
ehemaligen Bundesgesundheitsamtes)
The spectrum of chemical compounds in German households mainly comprises 40 potentially harmful substances and the most important classes of compounds are (survey by the former Federal Health Office)
- - Formaldehyd und höhere Aldehyde- formaldehyde and higher aldehydes
- - Weichmacher als Phthalate- plasticizers as phthalates
- - Isocyanate und Asbest- Isocyanates and asbestos
- - Mikrobielle verursachte Allergene durch Schimmelpilze- Microbial allergens caused by mold
- - Pentachlorphenol und Chlornaphtahline- pentachlorophenol and chloronaphtahline
- - Polychlorierte Biphenyle, Pyrethroide, Pestizide- Polychlorinated biphenyls, pyrethroids, pesticides
- - Aromaten, Terpene, Aldehyde, Ketone, Ester, Alkane und Alkohole- aromatics, terpenes, aldehydes, ketones, esters, alkanes and alcohols
Dieser Sachstand hat bereits einige Entwicklungen ausgelöst, um einige der aufgeführten
Schadstoffe zu eliminieren, wie z. B.
This state of affairs has already triggered some developments to eliminate some of the pollutants listed, such as. B.
- - Einsatz von Zimmerpflanzen als Luftfilter (z. B. Firma Botanis) als eine NASA-Entwicklung- Use of house plants as an air filter (e.g. Botanis) as a NASA development
- - Speziallacke zur Abdichtung schadstoffabgebender Bauteile- Special paints for sealing pollutant-emitting components
- - Allergenfiltersysteme und Hochleistungs-Luftfiltergeräte- Allergen filter systems and high-performance air filter devices
- - Ionisatoren zur Entfernung von Feinstäuben und Fremdstoffen- Ionizers to remove fine dust and foreign matter
Verschiedene Zimmerpflanzen vertilgen Schadstoffe. Mit dem Ventilator wird die Zimmerluft durch eine Befeuchtungseinrichtung und Pflanzen in einer Hydrokultur geleitet, um die Schadstoffe zu eliminieren (DE 41 33 663), ein Ozonisator zugeschaltet (DE 42 13 778) oder durch angesiedelte natürliche Mikroorganismen wird versucht, die aufgenommenen Schadstoffe mikroskopisch wieder abzubauen (DE 43 09 979). In der Regel wird die Raumluft durch Ventilatoren aktiv durch die Pflanzenkörbe geleitet (NASA, Botanis).Various houseplants destroy pollutants. With the fan, the room air passed through a humidifier and plants in a hydroponic to the To eliminate pollutants (DE 41 33 663), an ozonizer (DE 42 13 778) or by settled natural microorganisms try to absorb the pollutants to dismantle microscopically (DE 43 09 979). As a rule, the room air is through Fans actively guided through the plant baskets (NASA, Botanis).
Holzschutzmittelkontaminationen oder die Anwesenheit von polychlorierten Biphenylen werden durch das Auftragen einer dampfdichten Beschichtung mit Langzeitwirkung versiegelt (Biophillack von Imparat oder Schadstoffvernichter der Baden-Chemie).Wood preservative contamination or the presence of polychlorinated biphenyls sealed with a long-term effect by applying a vapor-tight coating (Biophillack from Imparat or pollutant destroyer from Baden-Chemie).
Der Mangel an negativen Ionen (Ionenungleichgewicht) wird oft mit dem Zustand einer schlechten Wohnraumluft gleichgesetzt. Ionisatoren erzeugen die gewünschten negativen Ionen, die sich an Schwebeteilchen anlagern, diese dann umpolen und zur Ablagerung an positiv geladenen Gegenständen bewegen, ohne daß sie mehr eingeatmet werden. The lack of negative ions (ion imbalance) is often associated with the condition of one poor living space equated. Ionizers generate the desired negative ions, which attach themselves to floating particles, then reverse the polarity and positive for deposition move charged objects without being inhaled more.
Dieser Effekt beschränkt sich hauptsächlich auf Partikel und Pollen bis 0,1 nm. Die haben aber keine Wirkung auf Gase und Dämpfe (Henava, Casadron).This effect is mainly limited to particles and pollen up to 0.1 nm no effect on gases and vapors (Henava, Casadron).
Sie werden oft kombiniert mit einem Hochleistungs-Luftreiniger (Aktivkohle) und Duftstoftkassetten, die zur Verbesserung der Innenraumluft eingesetzt werden. Durch stufenweise eingebaute Filtereinsätze sollen 99% der Fremdstoffe bis hin zu Bakterien und Keimen eleminiert werden. Die Leistung der Filter (ca. 125 m3/h) ist den Räumlichkeiten angepaßt. Auch für Kunstgegenständen in Vitrinen werden Filtermatten auf Aktivkohlebasis eingesetzt. In der Patentliteratur werden sehr unterschiedliche Absorptionsmedien eingesetzt, um die Wohnraumluft zu reinigen. Durch ein elektrostatisches Feld (OS 35 38 135), durch eine Kombination von Natronkalk, mehrbasische Carbonsäuren, Eisenhydroxid und Aktivkohle (36 23 731), UV-Struktur (37 24 050 und DE 41 30 648) werden bestimmte Luftreinigungseffekte erzielt.They are often combined with a high-performance air purifier (activated carbon) and fragrance cartridges, which are used to improve indoor air. Step-by-step filter inserts are designed to eliminate 99% of the foreign matter, including bacteria and germs. The performance of the filter (approx. 125 m 3 / h) is adapted to the premises. Active carbon-based filter mats are also used for art objects in showcases. In the patent literature, very different absorption media are used to clean the air in the living area. Through an electrostatic field (OS 35 38 135), through a combination of soda lime, polybasic carboxylic acids, iron hydroxide and activated carbon (36 23 731), UV structure (37 24 050 and DE 41 30 648) certain air cleaning effects are achieved.
Verschiedene Pflanzen sind in der Lage, bestimmte Schadstoffe zu vertilgen. Die Pflanzenkörbe sind wirksamer, wo die Innenraumluft mittels eines Ventilators durch eine Mischung von Aktivkohle, Hydropflanze mit Wurzelwerk und natürlichen Mikroorganismen (zur Regenerierung) geleitet wird. Allerdings bleibt die Wirkung nur auf wenige Schadstoffe - in der Regel wasserlösliche - beschränkt.Different plants are able to destroy certain pollutants. The plant baskets are more effective where the indoor air by means of a fan by a mixture of Activated carbon, hydro plant with roots and natural microorganisms (for Regeneration). However, the effect remains on only a few pollutants - in the Usually water soluble - limited.
Ionisatoren haben keine Wirkung gegenüber gas- bzw. dampfförmigen Schadstoffen, die die Vielzahl der Innenraumschadstoffe prägen. Auch dampfdichte Beschichtungen haben eine nur spezifische Wirkung gegenüber 2 bis 3 Substanzklassen.Ionizers have no effect on gaseous or vaporous pollutants that Characterize a large number of indoor pollutants. Vapor-proof coatings also only have one specific effect against 2 to 3 substance classes.
Die vielseitigste und wirksamste Form der Innenraumluftreinigung sind die Hochleistungsfilter - meist auf der Grundlage der Aktivkohle. Das Problem ist, daß die Beladungskapazität der Aktivkohleprüfung nur empirisch abgeschätzt werden kann und bei Schadstoffdurchbrüchen eine höhere Gefährdung ausgeht.The most versatile and effective form of indoor air purification are the high-performance filters - mostly based on activated carbon. The problem is that the loading capacity of the Activated carbon testing can only be estimated empirically and a when pollutant breakthroughs occur is more dangerous.
Das Ziel der Erfindung ist, durch einen speziellen Wandanstich auf der Basis einer weißen Grundfarbe, die auf Bedarf pigmentiert werden kann, die bekannte Vielzahl der Innenraumschadstoffe zu absorbieren und unter den raumklimatischen Bedingungen irreversibel zu fixieren. Dem Gedanken kommt entgegen, daß das Raum-Oberflächenverhältnis von Aufenthaltsräumen deutlich durch die Fläche des Wandanstriches beeinflußt wird. The aim of the invention is through a special wall puncture based on a white Base color, which can be pigmented on demand, the well-known variety of Absorb indoor pollutants and irreversible under the indoor climate conditions to fix. The thought is in agreement that the space-surface ratio of Lounges is significantly affected by the area of the wall paint.
Ein Modellraum von 50 m3 Inhalt bietet eine Anstrichfläche von 60 m2 und bei einem angenommenen Flächengewicht von 200 g/m2 stehen den 50 m3 Inhalt eine wirksame Absorbensmasse von 12 kg gegenüber.A model room of 50 m 3 content offers a painting area of 60 m 2 and with an assumed basis weight of 200 g / m 2 the 50 m 3 content is offset by an effective absorbent mass of 12 kg.
Wird eine Beladungskapazität von 0,5% angenommen und die Raumluft mit einer Belastung von 300 µg/m3/d angesetzt, dann ergäbe sich in grober Näherung eine Reinhalteeffekt von knapp 11 Jahren - eine Zeit, in der eine oder zwei Wandanstricherneuerung vorgenommen werden.If a loading capacity of 0.5% is assumed and the air in the room is exposed to a load of 300 µg / m 3 / d, this would result in a rough approximation of just under 11 years - a time in which one or two wall paints are renewed.
Nachdem rechnerisch die völlig ausreichende Beladungskapazität gegenüber einer typischen
Schadstoffbelastung der Innenraumluft festgestellt wurde, ergeben sich noch weitere
Vorbedingungen wie:
After the computationally sufficient loading capacity compared to a typical pollutant load in the indoor air has been determined, there are further preconditions such as:
- - Die Absorptionswirkung muß gegenüber den schwankenden Jahresfeuchtewerten konstant bleiben, da Wasserdampf bei vielen Sorbentien ein Konkurrent um die freien Adsorptionsplätze ist.- The absorption effect must be constant compared to the fluctuating annual moisture values remain, since water vapor competes for the free with many sorbents Adsorption sites is.
- - Die Desorptionswirkung darf nicht bei erhöhten Zimmertemperaturen <50°C eintreten.- The desorption effect must not occur at elevated room temperatures <50 ° C.
- - Zugesetzte Bindemittel dürfen den Gaszutritt nicht blockieren.- Added binders must not block gas access.
- - Die Absorptionswirkung muß ausreichend für die Absorption sein, wobei die betriebenen Heizkörper diese unterstützen.- The absorption effect must be sufficient for absorption, the operated Radiators support this.
Erfindungsgemäß wird das Problem so gelöst, daß der Wandanstrich aus einer Mischung aus Zeolithen und Kieselgel besteht, den zum inneren Halt ein Bindemittel (z. B. Methylullulose) beigemischt werden.According to the invention the problem is solved so that the wall paint from a mixture Zeolites and silica gel, which are bound by a binder (e.g. methylullulose) be added.
Zeolithe weisen auf Grund ihrer Kristallstruktur ein dreidimensionales Gitter auf, das in regelmäßigen Abständen von einem Kanalsystem definierter Porengröße durchzogen ist und hauptsächlich aus unlöslichen Alkalialuminiumsilikal besteht. Es entwickelt im Wasser ausgesprochene Ionenaustauschereigenschaften und bindet beispielsweise Härtebildner, Ammonium und Schwermetalle. Ähnlich gute Eigenschaften entwickelt es gegenüber den typischen gas- bzw. dampfförmigen Komponenten des Luftmediums.Due to their crystal structure, zeolites have a three-dimensional lattice, which in is regularly traversed by a channel system of defined pore size and consists mainly of insoluble alkali aluminum silicate. It develops in the water pronounced ion exchange properties and binds, for example, hardening agents, Ammonium and heavy metals. It develops similarly good properties compared to typical gaseous or vaporous components of the air medium.
Sehr vorteilhaft ist hier die Eigenschaft, im Absorptionsverhalten weniger von der Luftfeuchte beeinflußt zu werden. The property is very advantageous in terms of absorption behavior, less of the air humidity to be influenced.
Die Breite der Absorptionsfähigkeit wurde mittels FID bzw. ECD-Gaschromatographie an folgenden raumlufttypischen Substanzen nachgewiesen: 1-Propanol, n-Ethylacetat, Methylethylketon, Benzol, Toluol, Xylol, n-Butylacetat, 1-Octen-3-ol (Schimmelpilzprodukt), Lineol, Limonen, Dodecan, Butoxyethylacetat, Trichlorethylen und Tetrachlorkohlenstoff.The width of the absorption capacity was determined using FID or ECD gas chromatography the following substances typical of indoor air are detected: 1-propanol, n-ethyl acetate, Methyl ethyl ketone, benzene, toluene, xylene, n-butyl acetate, 1-octen-3-ol (mold product), Lineol, limonene, dodecane, butoxyethyl acetate, trichlorethylene and carbon tetrachloride.
Weiterhin wurde nachgewiesen, daß alle geprüften Substanzen bei Raumtemperatur und normaler Raumfeuchte vom Zeolith absorbiert werden und erst sichtbar ab 110°C die ersten Mengen wieder abgegeben - also ein Bereich, der unter Wohnbedingungen nicht in Frage kommt, aber eine Regenerierung von Altanstrichen erlaubt.It was also demonstrated that all tested substances at room temperature and normal room humidity are absorbed by the zeolite and the first visible only at 110 ° C Quantities released again - an area that is out of the question under living conditions comes, but allows regeneration of old coatings.
Damit werden die vorgenannten Bedingungen erfüllt mit Ausnahme der Absorptionsfähigkeit gegenüber dem bekannten Wohngift Formaldehyd. Zur ausreichenden Entfernung dieses Schadstoffes war es erforderlich, auf Kieselgel, das bekanntlicherweise zu diesen Absorptionen in Silicagelröhrchen eingesetzt wird, zurückzugreifen.This means that the above conditions are met with the exception of absorbency compared to the well-known residential poison formaldehyde. To adequately remove this Pollutant was required on silica gel, which is known to cause these absorptions used in silica gel tubes.
Das Mischungsverhältnis zwischen den Zeolithen und Kieselgel kann variabel gestaltet werden, sollte sich aber im Verhältnis 10-25 : 1 bewegen.The mixing ratio between the zeolites and silica gel can be varied, but should be in the 10-25: 1 ratio.
Eine noch bessere Wirkung im Absorptionsvermögen gegenüber den raumlufttypischen Schadstoffen zeigen organophile Bentonite (z. B. Tixogel der Südchemie AG), die u. a. als Thixotropier und Antiabsetzmittel bei industriellen Herstellungsprozessen mit organischen Lösemitteln eingesetzt werden. Diese potentielle Neigung für die Lösemittelverträglichkeit in Lösungen wird hier zur Absorption von gasförmigen Schadstoffen ausgenutzt.An even better effect in terms of absorbency compared to those typical of indoor air Organophilic bentonites (e.g. Tixogel from Südchemie AG) show harmful substances. a. as Thixotropic and anti-settling agent in industrial manufacturing processes with organic Solvents are used. This potential tendency for solvent compatibility in Solutions are used here for the absorption of gaseous pollutants.
