Abstract

Filter consists of air-permeable support (I) with adsorber resin (II) fixed thereon. Also claimed is system for introducing fresh air into vehicle cabins, contg. such a filter for removing unpleasant odours (partic., diesel fumes) in road traffic. Pref. (I) is 3-dimensional. (I) is open-pored, crosslinked polyurethane (PU) foam. Adhesive compsn. (by which (II) is fixed to (I)) is reactive system passing through min. viscosity before reaching crosslinking temp. Adhesive compsn. contains flame retardant. (II) comprises spheres of average dia. 0.3-0.6 mm. (II) has very regular miropore system with practically identical pore dia. each of 5-10 Angstroms, and micropores are readily accessible through macropores. (II) is based on polymer or copolymer of divinylbenzene and vinylbenzene. (II) is insensitive to moisture. ADVANTAGE - (II), developed for recovery of solvents from water, and contg. divinylbenzene, with very regular microporous system, is very effective at absorbing odours and is hydrophobic. In an example, open-pored, crosslinked PU foam, pore size 15-20 PPI 10 mm thick, density 30 g/l was treated with 25-36 g PU reactive system per 1 foam then Sorbathen (TM) spheres of 0.5 mm (dia.) were sprinkled on; they adhered well, due to tackiness of PU system. On heating to 165 deg.C, viscosity of PU compsn. first decreased sharply (resulting in good bonding of spheres), then from 140 deg.C croslsinkincrosslinking occurred, PU compsn. solidifying.

Description

Die Offenlegungsschrift DE 32 18156 A1 beschreibt Filtersysteme, mit deren Hilfe Schad- und Geruchsstoffe aus Luftströmen entfernt werden können. Als Anwen­ dungsgebiete werden Innenräume, aber auch Fahrzeugkabinen genannt.The published patent application DE 32 18156 A1 describes filter systems with the help of which Pollutants and odors can be removed from air currents. As a user areas are called interiors, but also vehicle cabins.

Wie Insassen von Fahrzeugen, insbesondere von Kraftfahrzeugen, sind zwei Ein­ flüssen ausgesetzt: den sog. Schadstoffen, wie Co, NOx und in geringerem Maß SO₂, die man nicht oder kaum riecht, sofern keine hohen Konzentrationen vorlie­ gen, und Geruchsstoffen, die zum Großteil aus unvollständig Kraftstoff, insbesondere Dieselkraftstoff, bestehen.How occupants of vehicles, especially motor vehicles, are exposed to two influences: the so-called pollutants, such as Co, NO x and, to a lesser extent, SO₂, which one does not smell or hardly smells, as long as there are no high concentrations, and odorous substances that are used for Most consist of incomplete fuel, especially diesel fuel.

Während für den normalen Kraftfahrzeugbenutzer die Schadstoffe keine ernste Bedrohung bedeuten und man ihn deshalb nicht vor diesen Stoffen schützen muß, bedeuten dagegen Geruchsstoffe eine sehr erhebliche Belästigung.While for the normal motor vehicle user the pollutants are not serious Mean a threat and therefore you do not have to protect him from these substances, on the other hand, odorous substances are a very significant nuisance.

Schadstoffe wie Co und NOx sind nach heutigem Stand der Technik nur schwer eli­ minierbar und wenn, dann nur mit aufwendigen, voluminösen Filtersystemen, für die normalerweise gar kein Platz vorhanden ist.According to the current state of the art, pollutants such as Co and NO x are difficult to eliminate and, if so, only with complex, voluminous filter systems for which there is normally no space.

Gerüche sind nicht meßbar, sie sind eine Empfindung. Ihre Besonderheit liegt darin, daß sie schon in geringsten Konzentrationen wahrnehmbar sind bzw. wenn es sich um unangenehme Gerüche handelt, als Belästigung empfunden werden. So konnte anhand von Versuchen mit einem stationären Diesel festgestellt werden, daß selbst bei 100 000facher Verdünnung der Abgase mit Frischluft ein unange­ nehmer Geruch wahrnehmbar ist. Es ist deshalb nicht erstaunlich, wenn es beson­ derer Filter bedurfte, um die Gerüche des Straßenverkehrs von der Fahrzeugkabi­ ne fernzuhalten.Smells are not measurable, they are a sensation. Your peculiarity lies in that they are perceptible even in the smallest concentrations or if it is an unpleasant smell that is perceived as a nuisance. So it could be determined by tests with a stationary diesel,  that even with 100,000 times dilution of the exhaust gases with fresh air an uncomfortable pleasant smell is noticeable. It is therefore not surprising if it is special whose filter needed to remove the smells of road traffic from the vehicle cab ne to keep away.

Eine in der DE 32 28 156 A1 beschriebene bevorzugte Form besteht aus einem großporigen, retikulierten PU-Schaum, der mit einer Haftmasse beaufschlagt wird und dann mit Aktivkohleteilchen, insbesondere 0,4-1,0 mm große Aktivkohlekü­ gelchen, bestreut wird. Durch die besondere Art der Haftmasse bilden sich kleine "Tragsockeln" aus, die in der genannten Anmeldung als Tragsäulen bezeichnet sind, was aber zu einer falschen Vorstellung führt. Ein Filter dieser Art wird dem­ nächst von einem bekannten Automobilhersteller als Ergänzung zur Klimaanlage eingeführt.A preferred form described in DE 32 28 156 A1 consists of a large-pored, reticulated PU foam, which is applied with an adhesive and then with activated carbon particles, in particular 0.4-1.0 mm activated carbon gelchen, is sprinkled. Due to the special nature of the adhesive, small ones are formed "Support base", referred to in the application as support columns are, which leads to a wrong idea. A filter of this type is the next from a well-known automobile manufacturer as a supplement to the air conditioning system introduced.

Das grundsätzliche Prinzip der dreidimensionalen Matrix, an welcher relativ kleine Adsorberteilchen haften, ist in der Offenlegungsschrift DE 38 13 563 A1 enthalten. Die Vorteile sind: ein sehr geringer Druckabfall und, als Folge der kleinen Teilchen, eine sehr gute Adsorptions- und Desorptionskinetik. Der geringe Druckabfall ist für die Anwendung solcher Filter in Kraftfahrzeugen von enormer Wichtigkeit, weil die Gebläseleistung kaum gesteigert werden kann, die Menge Frischluft jedoch nicht erheblich reduziert werden darf, wenn man ein Filter nutzt.The basic principle of the three-dimensional matrix, on which relatively small Adhesor particles stick, is contained in the published patent application DE 38 13 563 A1. The advantages are: a very low pressure drop and, as a result of the small particles, very good adsorption and desorption kinetics. The low pressure drop is for the application of such filters in motor vehicles is of enormous importance because the Fan performance can hardly be increased, but the amount of fresh air cannot may be significantly reduced if you use a filter.

Die gebräuchlichen Adsorbentien sind auf Basis von Aktivkohle. Aktivkohle nimmt bekannterweise ab einer relativen Feuchte von 70% schnell bis zu 30% ihres Gewichts an Wasser auf, wodurch ihre Adsorptionsfähigkeit geschmälert wird. Ein anderer Nachteil ist, daß ein solches Filter bei feuchter Witterung Feuchtigkeit auch im Ruhezustand aufnimmt und diese an den Innenraum abgeben kann. Bei 1 kg Kohle sind das immerhin 0,3 l Wasser, was zum Beschlagen der Scheiben führen kann. Dies mag auch der Grund sein, warum der Einsatz derartiger Filter vorerst nur zusammen mit einer Klimaanlage erfolgt. The usual adsorbents are based on activated carbon. Activated carbon takes As is known, from a relative humidity of 70% quickly up to 30% of their Weight of water, which reduces their adsorbability. A another disadvantage is that such a filter also damp in damp weather records in the idle state and can deliver this to the interior. At 1 kg Coal is at least 0.3 l of water, which leads to fogging of the windows can. This may also be the reason why the use of such filters for the time being only done together with air conditioning.  

Es wurde nun überraschenderweise gefunden, daß Adsorberharze, die für die Lösemittelrückgewinnung in flüssiger Phase entwickelt wurden, sich sehr gut zur Beseitigung der Geruchsbelästigung im Straßenverkehr eignen. Solche Harze sind Divinylbenzol enthaltende Produkte, die ein sehr regelmäßig aufgebautes Mikro­ porensystem enthalten, welches über Transportporen sehr gut zugänglich ist. Sie können auch als organische Zeolite bezeichnet werden. Eine wichtige Eigenschaft ist ihre Hydrophobie. Da die Adsorber für die Rückgewinnung von Lösemitteln aus Wasser entwickelt wurden, wurde auf eine sehr ausgeprägte Hydrophobie viel Wert gelegt. Da diese Adsorber keine Feuchtigkeit aufnehmen, ist auch das bei Verwen­ dung von Aktivkohle mögliche Beschlagen der Fenster nicht mehr zu befürchten. Das bedeutet, daß die erfindungsgemäßen Geruchsfilter für Fahrzeugkabinen all­ gemein einsetzbar sind, also auch ohne Klimaanlage. Wenn auch die erfindungs­ gemäßen Filter in erster Linie zur Beseitung von Gerüchen gedacht sind, so darf nicht übersehen werde, daß auch Schadstoffe, wie z. B. Kohlenwasserstoffe, Aromaten und deren Crackprodukte, die zwar nur in niedrigen Konzentrationen vorkommen, aber deren gesundheitliches Risiko noch lange nicht ausreichend er­ forscht ist, adsorbiert werden.It has now surprisingly been found that adsorber resins which are suitable for the Solvent recovery in the liquid phase have been developed very well Eliminate odors in road traffic. Such resins are Products containing divinylbenzene that have a very regular micro contain pore system, which is very accessible via transport pores. they can also be called organic zeolites. An important quality is their hydrophobicity. Because the adsorber is made for the recovery of solvents Water were developed, much emphasis was placed on a very pronounced hydrophobicity placed. Since these adsorbers do not absorb moisture, this is also the case with Verwen of activated carbon no longer have to fear possible fogging of the windows. This means that the odor filter according to the invention for vehicle cabins all can be used together, i.e. without air conditioning. If the invention filters are primarily intended to remove odors, so will not be overlooked that pollutants such. B. hydrocarbons, Aromatics and their cracking products, although only in low concentrations occur, but their health risk is still insufficient research is adsorbed.

Beispiel 1Example 1

Ein offenporiger, retikulierter PU-Schaum, Porengröße ca. 15-20 PPl, Dicke 10 mm, Litergewicht ca. 30 g, wurde mit einem PU-Reaktivsystem ("Hig Solid", Bayer AG) heaufschlagt (25-36 g/l Schaum) und mit Sorbathen-Kügelchen (DOW Chemical Corp.) von ca. 0,5 mm bestreut. Durch die hervorragende Klebrigkeit der Haftmasse war die nötige Anfangshaftung gewährleistet. Beim Erhitzen bis auf 160°C nahm zuerst die Viskosität der Haftmasse stark ab, wodurch einerseits eine hervorragende Verklebung, andererseits eine Art von "Tragesockel" (Einschnürung) unter jedem Kügelchen entstand, welche die Zugänglichkeit noch verbesserte. Ab 140°C trat die Vernetzung ein, wodurch die Haftmasse erstarrte. An open-pore, reticulated PU foam, pore size approx. 15-20 PPl, thickness 10 mm, Liter weight approx. 30 g, was with a PU reactive system ("Hig Solid", Bayer AG) opened (25-36 g / l foam) and with sorbate beads (DOW Chemical Corp.) of about 0.5 mm. Due to the excellent stickiness of the adhesive the necessary initial liability was guaranteed. When heated to 160 ° C First the viscosity of the adhesive mass drops sharply, which on the one hand makes it excellent Gluing, on the other hand a kind of "support base" (constriction) under each bead was created, which made accessibility even better. From 140 ° C networking occurred, causing the adhesive to freeze.  

Beispiel 2Example 2

Wie Beispiel 1, mit dem Unterschied, daß den High Solids 15 Gew.-% eines Halo­ genfreien Flammschutzmittels zugefügt wurde. Die Ergebnisse wurden nicht be­ einflußt.As example 1, with the difference that the high solids 15 wt .-% of a halo gene-free flame retardant was added. The results were not influences.

Auf einem Prüfstand (VW, 6-Zyl. Diesel, 2000 T/min., Normallast) wurden Dieselab­ gase bis zu einer Verdünnung 1 : 100 000 auf Gerüche geprüft (Testpersonen), wobei die Dieselgerüche noch wahrnehmbar waren. Sodann wurden Abgase in einer Verdünnung von nur 1 : 1000 durch ein Geruchsfilter, bestehend aus 6 Lagen des Schaums von Beispiel 1 bzw. 2 geleitet. Die Gerüche waren eliminiert.On a test bench (VW, 6-cyl. Diesel, 2000 T / min., Normal load), diesel were released gases up to a dilution of 1: 100,000 tested for odors (test persons), the diesel smells were still noticeable. Exhaust gases were then a dilution of only 1: 1000 through an odor filter consisting of 6 layers the foam of Example 1 and 2 passed. The smells were eliminated.
