Die vorliegende Patentanmeldung nimmt die Priorität der deutschen Patentanmeldung DE 10 2015 222 486.4 in Anspruch, deren Inhalt durch Be- zugnahme hierin aufgenommen wird. The present patent application claims the priority of German Patent Application DE 10 2015 222 486.4, the content of which is incorporated herein by reference.
Die Erfindung betrifft ein Neutralisations-Additiv zum Einsatz in Silikon- Produkten, die mit schwefelbasierten Geruchsstoffen in Kontakt kommen und seine Verwendung in polymeren Grundmaterialien zur Neutralisierung und Aufspaltung von geruchsbildenden Molekülen. The invention relates to a neutralization additive for use in silicone products which come into contact with sulfur-based odorous substances and its use in polymeric base materials for the neutralization and decomposition of odor-forming molecules.
So kann das Neutralisations-Additiv in einem medizinischen oder pharmazeutischen Produkt verwendet werden. Ein Beispiel für eine derartige medizinische Produktanwendung ist ein Rektalkatheter. Thus, the neutralization additive can be used in a medical or pharmaceutical product. An example of such a medical product application is a rectal catheter.
Grundsätzlich kann das Neutralisations-Additiv auch außerhalb der medizinischen oder pharmazeutischen Anwendung zum Einsatz kommen, nämlich generell dort, wo durch die Diffusion von geruchsintensiven Molekülen durch eine Schlauchwand anwendungsbedingt mit einer unerwünschten Geruchsentwicklung zu rechnen ist. Derartige weitere Anwendungen sind beispielsweise Gasleitungen aus Kunststoff, bei denen ein entsprechendes Neutralisations-Additiv beispielsweise eine Unterscheidung einer Wanddiffusion von einer echten Leckage ermöglicht und somit eine Leckagedetek- tion ermöglicht ist. Weitere Anwendungsbeispiele sind Rohrleitungen und deren Kompensatoren, wie sie z.B. bei Erdölleitungen oder Biogasanlagen Verwendung finden. Ein weiteres Anwendungsbeispiel unabhängig von einer medizinischen oder pharmazeutischen Anwendung, bei dem ein entsprechendes Neutralisations-Additiv eingesetzt werden kann, ist eine Dichtung. Auch Beschichtungen und Auskleidungen von Tanks sind geeignete Anwendungsbeispiele. Als polymeres Grundmaterial kommt Silikon zum Einsatz. Bei einem hiervon unabhängigen Aspekt kann als polymeres Grundmaterial auch ein thermosplastisches Elastomer (TPE) zum Einsatz kommen. In principle, the neutralization additive can also be used outside the medical or pharmaceutical application, namely generally where, due to the application, an undesirable odor development is to be expected due to the diffusion of odor-intensive molecules through a hose wall. Such further applications are, for example, gas lines made of plastic, in which a corresponding neutralization additive allows, for example, a distinction of wall diffusion from a true leakage and thus a leakage detection is possible. Other application examples are pipelines and their compensators, such as those used in petroleum pipes or biogas plants. Another application example, independent of a medical or pharmaceutical application in which a corresponding neutralization additive can be used, is a seal. Also coatings and linings of tanks are suitable Application examples. As a polymeric base material silicone is used. In the case of an independent aspect, a thermosplastic elastomer (TPE) can also be used as the polymeric base material.
Stoffgemische, die schwefelbasierte Geruchsstoffe enthalten, treten in Erdölraffinerien, bei dem Transport von Erdöl, bei der Herstellung von Biogas und Biodiesel auf. In diesen Bereichen ist eine Geruchsreduzierung durch die Bindung dieser Geruchsstoffe an ein Neutralisations-Additiv möglich. Substances that contain sulfur-based odors are found in oil refineries, in the transportation of oil, in the production of biogas and biodiesel. In these areas, odor reduction is possible by binding these odorous substances to a neutralization additive.
In Faultürmen, Kläranlagen, Sanitäreinrichtungen wie mobilen Toiletten (u.a. in Wohnmobilen), in der Kanalisation oder auch auf Mülldeponien entstehen schwefelhaltige Gase, deren schwefelhaltige Komponenten einen starken Geruch verursachen. Eine Geruchsminderung kann erreicht wer- den, wenn mit einem Neutralisations-Additiv versehene Silikonschläuche bzw. mit Silikon ausgekleidete Leitungen und Behälter verwendet werden. In digestion towers, sewage treatment plants, sanitary facilities such as mobile toilets (including motorhomes), sewers and landfills, sulfur-containing gases are produced whose sulfur-containing components cause a strong odor. Odor reduction can be achieved by using silicone tubing or silicone lined tubing and tubing with a neutralizing additive.
Schwefelhaltige chemische Erzeugnisse, wie z.B. Mercaptane, besitzen einen starken Eigengeruch. Die Geruchsbelästigung während des Herstel- lungsprozesses, der Lagerung und des Transports kann durch Verwendung von einem mit einem Neutralisations-Additiv versehenen Silikonschlauch bzw. von mit Silikon ausgekleidete Leitungen und Behälter gemindert werden. Die EP 2 620 168 AI beschreibt die Herstellung eines Schlauchs mit Geruchsbarriere für den Einsatz als Katheter. In der EP 2 001 671 Bl wird ein mehrschichtiges Material beschrieben, das sich für den Einsatz in geruchsintensiven Bereichen, z.B. als geruchshemmende Substanz in einem Katheterbeutel eignet. In der WO 2013/043 226 AI wird ein geruchshemmendes Material beschrieben, das für den Einsatz in Kathetern oder Fäkalienbeuteln geeignet ist. Sulfur-containing chemicals, such as mercaptans, have a strong odor. The odor nuisance during the manufacturing process, the storage and the transport can be reduced by using a silicone tube provided with a neutralization additive or by silicone-lined lines and containers. EP 2 620 168 A1 describes the production of a tube with an odor barrier for use as a catheter. EP 2 001 671 B1 describes a multilayer material which is suitable for use in odor-intensive areas, for example as an odor-inhibiting substance in a catheter bag.

Je nach Anwendung kann gewünscht sein, dass ein Geruch eines Mediums, dem ein Produkt ausgesetzt ist, nicht nach außen dringt, so dass es zu kei- ner unerwünschten Geruchsbelästigung einer äußeren Umgebung kommt. Dementsprechend ist es Aufgabe der vorliegenden Erfindung, ein Neutralisations-Additiv bereitzustellen, das die Freisetzung von geruchsbildenden Verbindungen in eine äußere Umgebung zumindest weitgehend verhindert und sich mit einem polymeren Grundmaterial zu einem Produkt formen lässt. Depending on the application, it may be desired that a smell of a medium to which a product is exposed does not escape to the outside, so that there is no undesirable odor nuisance of an external environment. Accordingly, it is an object of the present invention to provide a neutralization additive which at least substantially prevents the release of odoriferous compounds into an external environment and can be formed into a product with a polymeric base material.
Diese Aufgabe ist erfindungsgemäß gelöst durch ein Neutralisations- Additiv mit den im Anspruch 1 angegebenen Merkmalen. Das im Neutralisations-Additiv vorliegende Adsorbens und das katalyti- sche Material sorgen für eine Neutralisierung geruchsbildender Moleküle. Das Adsorbens kann insbesondere Schwefelverbindungen neutralisieren. Geruchsbildende Schwefelverbindungen sind u.a. Schwefelwasserstoff, Methanthiol, Allylmethylsulfid, Disulfide (wie z.B. Dimethyldisulfid, Me- thylpropyldisulfid, Dipropyldisulfid, cis-Propenylpropyldisulfid, trans- Propenylpropyldisulfid) und Trisulfide (wie z.B. Dimethyltrisulfid). Das Adsorbens kann eine große aktive Oberfläche aufweisen. Das Adsorbens weist insbesondere eine BET-Oberfläche von 100 - 600 m2/g, bevorzugt von 250 - 500 m2/g, besonders bevorzugt von 300 - 400m2/g, auf. Die ak- tive Oberfläche des Adsorbens wird dabei nach der BET(Brunauer, Em- mett, Teller)-Methode (vgl. DIN 66131 und ISO 9277) bestimmt und wird auch als BET-Oberfläche bezeichnet. Die BET-Oberfläche wird am pulver- förmigen Material oder an Tabletten entsprechend DIN 66131 bestimmt. This object is achieved by a neutralization additive having the features specified in claim 1. The adsorbent present in the neutralization additive and the catalytic material neutralize odor-forming molecules. In particular, the adsorbent can neutralize sulfur compounds. Odor-forming sulfur compounds include hydrogen sulfide, methanethiol, allyl methyl sulfide, disulfides (such as dimethyl disulfide, methyl propyl disulfide, dipropyl disulfide, cis propenyl propyl disulfide, trans propenyl propyl disulfide) and trisulfides (such as dimethyl trisulfide). The adsorbent may have a large active surface area. In particular, the adsorbent has a BET surface area of 100 - 600 m 2 / g, preferably from 250 - 500 m 2 / g, more preferably of 300 - 400m 2 / g. The ak- The surface of the adsorbent is determined by the BET (Brunauer, Emett, Teller) method (see DIN 66131 and ISO 9277) and is also referred to as BET surface area. The BET surface area is determined on the powdery material or on tablets according to DIN 66131.
Das katalytische Material kann für eine Aufspaltung geruchsbildender und damit störender Moleküle sorgen. Das Adsorbens und das katalytische Material sind daher zur Ausbildung der Geruchsbarriere geeignet, indem die geruchsbildenden Moleküle entweder adsorbiert oder in kleinere, nicht mehr geruchsbildende Moleküle aufgespalten werden. Das katalytische Material kann auch dann noch geruchshemmend und jedenfalls geruchsmindernd wirken, wenn eine Beladung des Adsorbens bereits eine kritische Beladungsgrenze überschreitet. Soweit nach Anspruch 2 das katalytische Material als Komponente des Adsorbens vorliegt, vereinbart das Adsorbens die Funktionen„Neutralisierung" und„katalytische Beseitigung störender Gerüche". The catalytic material can cause a breakdown of odoriferous and thus disturbing molecules. The adsorbent and catalytic material are therefore suitable for forming the odor barrier by either adsorbing the odor-forming molecules or breaking them down into smaller, no longer odor-forming molecules. The catalytic material can also odor-inhibiting and odor-reducing effect even if a loading of the adsorbent already exceeds a critical loading limit. As far as according to claim 2, the catalytic material is present as a component of the adsorbent, the adsorbent agrees the functions "neutralization" and "catalytic elimination of offensive odors".
Alternativ oder zusätzlich kann nach Anspruch 3 das katalytische Material als zusätzlich zum Adsorbens vorhandene Komponente vorliegen. Ein derart in dem Neutralisations-Additiv vorliegendes zusätzliches katalytisch aktives Material ist geeignet, geruchsbildende Moleküle aufzuspalten. Dabei kann es auch Moleküle aufspalten, die aufgrund ihrer Größe nicht an dem Adsorbermaterial adsorbiert werden können. Nach der Aufspaltung liegen diese Moleküle als kleinere Moleküle vor und können im folgenden Schritt am Adsorbens adsorbiert werden und aufgrund seiner katalytischen Funktion weiter aufgespalten werden. Das in dem Neutralisations-Additiv vorliegende katalytische Material kann ein Metall, insbesondere mit einer Oxidations stufe ungleich 0, oder eine nichtmetallische Komponente bzw. eine nichtmetallische Verbindung umfassen. Bei einer alternativen Ausgestaltung des katalytischen Materials kann dieses sowohl eine metallische als auch eine nichtmetallische Komponente umfassen. Alternatively or additionally, according to claim 3, the catalytic material may be present as a component in addition to the adsorbent. Such an additional catalytically active material present in the neutralization additive is suitable for splitting odor-forming molecules. It can also split molecules that can not be adsorbed on the adsorbent due to their size. After cleavage, these molecules are present as smaller molecules and can be adsorbed on the adsorbent in the following step and further split due to its catalytic function. The catalytic material present in the neutralization additive may comprise a metal, in particular having an oxidation state not equal to 0, or a non-metallic component or a non-metallic compound. In an alternative embodiment of the catalytic material, this may comprise both a metallic and a non-metallic component.
Für metallhaltige Verbindungen nach Anspruch 4, die das katalytisch aktive Material umfasst, eignen sich insbesondere die Metalle Mangan, Zink, Eisen oder Edelmetalle oder eine Kombination von mindestens zweier dieser Metalle. Auch Edelstahl kann zum Einsatz kommen. For metal-containing compounds according to claim 4, which comprises the catalytically active material, in particular the metals manganese, zinc, iron or noble metals or a combination of at least two of these metals are suitable. Also stainless steel can be used.
Besonders geeignete Edelmetalle nach Anspruch 5 sind ausgewählt aus Platin, Gold, Silber, Kupfer oder einer Kombination von mindestens zwei dieser Edelmetalle. Bei einer alternativen Ausgestaltung des Neutralisations-Additivs kann als metallhaltige Verbindung auch eine solche Verbindung verwendet werden, bei der das Metallelement nicht als reines Metall, d.h. in der Oxidations stufe 0 vorliegt. Auch Kombinationen aus einem reinen Metall und Metallelement im nicht metallischen Zustand können zum Einsatz kommen. Particularly suitable noble metals according to claim 5 are selected from platinum, gold, silver, copper or a combination of at least two of these noble metals. In an alternative embodiment of the neutralization additive, the metal-containing compound may also be a compound in which the metal element is not used as a pure metal, i. in the oxidation stage 0 is present. Combinations of a pure metal and metal element in the non-metallic state can also be used.
Enthält das Neutralisations-Additiv Kupfer, liegt dieses bevorzugt in einem Anteil von mindestens 0,1 Gew.-%, besonders von 0,1 bis 10 Gew.-% vor. Dieser Kupferanteil kann sich in dem Adsorbens, enthaltend die katalyti- sehe Funktion, oder sich in dem weiteren katalytisch aktiven Material befinden. Contains the neutralization additive copper, this is preferably in a proportion of at least 0.1 wt .-%, especially from 0.1 to 10 wt .-% before. This proportion of copper may be located in the adsorbent containing the catalytic function or in the further catalytically active material.
Enthält das Neutralisations-Additiv Mangan, liegt dieses bevorzugt in einem Anteil von mindestens 10 Gew.-%, besonders von 10 bis 15 Gew.-% vor. Dieser Mangananteil kann sich in dem Adsorbens, enthaltend die kata- lytische Funktion, oder sich in dem weiteren katalytisch aktiven Material befinden. Enthält das Neutralisations-Additiv Zink, liegt dieses bevorzugt in einem Anteil von mindestens 20 Gew.-%, besonders von 20 bis 40 Gew.-% vor. Dieser Zinkanteil kann sich in dem Adsorbens, enthaltend die katalytische Funktion, oder sich in dem weiteren katalytisch aktiven Material befinden. Ein Molekularsieb nach Anspruch 6 stellt eine besonders effektive Variante eines Neutralisations-Additivs dar. Das Molekularsieb kann poröse Strukturen, insbesondere poröse kristalline Strukturen bereitstellen, deren Porengröße gezielt den zu bindenden geruchsbildenden Molekülen angepasst werden kann. Bei Einsatz eines Molekularsiebs kann der Katalysator so gewählt sein, dass er Moleküle aufspaltet, für deren unaufgespaltene Form die Poren des Molekularsiebs zu klein sind. If the neutralization additive contains manganese, it is preferably present in a proportion of at least 10% by weight, especially from 10 to 15% by weight. in front. This manganese fraction may be present in the adsorbent containing the catalytic function or in the further catalytically active material. Contains the neutralization additive zinc, this is preferably in a proportion of at least 20 wt .-%, especially from 20 to 40 wt .-% before. This zinc fraction may be in the adsorbent containing the catalytic function or in the further catalytically active material. A molecular sieve according to claim 6 represents a particularly effective variant of a neutralization additive. The molecular sieve can provide porous structures, in particular porous crystalline structures, whose pore size can be tailored to the odor-forming molecules to be bound. When using a molecular sieve, the catalyst may be chosen to break down molecules for the unseparated form of which the pores of the molecular sieve are too small.
Ein mikroporöses Material nach Anspruch 7, insbesondere ein Zeolith nach Anspruch 8, stellt ein besonders geeignetes Neutralisations-Additiv dar. Das mikroporöse Material, insbesondere der Zeolith, kann eine adsorbierende Wirkung haben. Es können natürlich vorkommende und/oder synthetisch hergestellte mikroporöse Strukturen, insbesondere Zeolith-Strukturen zum Einsatz kommen. Ein Zeolith der Topologie BEA nach Anspruch 9 stellt ein besonders geeignetes Neutralisations-Additiv dar. Bei dem Zeolith der Topologie BEA handelt es sich bevorzugt um einen synthetisch hergestellten Zeolithen. Auch ein anderes Zeolith-Material mit einem dreidimensionalen Kanalsystem kann zum Einsatz kommen. Als Beispiele sind Zeolithe mit MFI, FAU und MO Topologie zu nennen. Bezüglich der Nomenklatur der vorgenannten Topologien wird auf den„Atlas of Zeolite Framework Types", Ch. Baerlocher, 5th Edition, 2001 verwiesen, der eine Übersicht über die verschiedenen Topologien der Zeolithstrukturen liefert und dessen Offenba- rung diesbezüglich in die Beschreibung aufgenommen wird. A microporous material according to claim 7, in particular a zeolite according to claim 8, represents a particularly suitable neutralization additive. The microporous material, in particular the zeolite, may have an adsorbing effect. Naturally occurring and / or synthetically produced microporous structures, in particular zeolite structures, can be used. A zeolite of the topology BEA according to claim 9 represents a particularly suitable neutralization additive. The zeolite of the topology BEA is preferably a synthetically produced zeolite. Another zeolite material with a three-dimensional channel system can also be used. As examples are zeolites with MFI, FAU and to call MO topology. With regard to the nomenclature of the aforementioned topologies, reference is made to the "Atlas of Zeolite Framework Types", Ch. Baerlocher, 5th Edition, 2001, which provides an overview of the various topologies of the zeolite structures and the disclosure of which is included in the description.
Der Zeolith hat dabei insbesondere die Funktion, die geruchsbildenden Moleküle zu adsorbieren. Dies erfolgt aufgrund der spezifischen Zeolith- struktur, die Kanäle und/oder Hohlräume aufweist, die für Moleküle einer bestimmten Größe zugänglich sind. The zeolite has in particular the function of adsorbing the odoriferous molecules. This is due to the specific zeolite structure having channels and / or cavities accessible to molecules of a particular size.
Das katalytische Material in dem Neutralisations-Additiv kann entweder als eigene Verbindung neben dem Adsorbens vorliegen, insbesondere als metallhaltige Verbindung, ganz besonders in Form eines Oxids, Hydroxids, Carbonats oder Phosphats. The catalytic material in the neutralization additive may be present either as a separate compound adjacent to the adsorbent, especially as a metal-containing compound, more particularly in the form of an oxide, hydroxide, carbonate or phosphate.
Liegt das Adsorbens z.B. als Zeolith vor, kann dieser Zeolith zusätzlich metallhaltige Komponenten beinhalten, die entweder in Form einer reinen metallischen Phase, das bedeutet in der Oxidations stufe 0, oder in Form von Metallionen vorliegen. In diesem Fall liegt das katalytische Material des Neutralisations-Additivs in der Zeolithstruktur selber vor. If the adsorbent is e.g. as zeolite, this zeolite may additionally contain metal-containing components which are present either in the form of a pure metallic phase, that is to say in the oxidation state 0, or in the form of metal ions. In this case, the catalytic material of the neutralization additive is present in the zeolite structure itself.
Partikel mit einer Partikelgröße von 0,1 μηι bis 50,0 μηι, insbesondere von 1,0 bis 10 μηι nach Anspruch 10 haben sich für das Neutralisations-Additiv als besonders geeignet herausgestellt. Insbesondere das weitere katalytische Material weist eine Partikelgröße von 0,1 μηι bis 50,0 μηι, insbesondere von 1,0 bis 10,0 μηι auf. Zusätzlich kann das Adsorbens eine Partikelgröße von 0,1 μηι bis 50,0 μηι, insbesondere von 1,0 bis 10,0 μηι aufweisen. Eine Additivpaste nach Anspruch 1 1 ermöglicht eine exakte Vorbereitung einer Zusammensetzung des Neutralisations- Additivs. Die Paste ermöglicht eine ausreichende Materialdurchmischung mit dem polymeren Grundmate - rial. Die Herstellung der Additivpaste kann durch Dispergieren und insbesondere durch Fein-Dispergieren erfolgen. Particles having a particle size of 0.1 μηι to 50.0 μηι, in particular from 1.0 to 10 μηι according to claim 10 have been found to be particularly suitable for the neutralization additive. In particular, the further catalytic material has a particle size of 0.1 μηι to 50.0 μηι, in particular from 1.0 to 10.0 μηι. In addition, the adsorbent can have a particle size of from 0.1 μm to 50.0 μm, in particular from 1.0 to 10.0 μm. An additive paste according to claim 1 1 allows an exact preparation of a composition of the neutralization additive. The paste enables sufficient material mixing with the polymer base material. The preparation of the additive paste can be carried out by dispersing and in particular by fine dispersion.
