Der Erfindung liegt die Aufgabe zu Grunde, ein verbessertes Filtermedium anzugeben.The invention is based on the object to provide an improved filter medium.
Die Aufgabe wird erfindungsgemäß gelöst durch ein Filtermedium mit den Merkmalen des Anspruchs 1.The object is achieved by a filter medium having the features of claim 1.
Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of the dependent claims.
Ein Filtermedium mit biozider Wirkung zur Filterung von Luft für einen Innenraum eines Fahrzeugs besteht aus zumindest einer Filterschicht und zumindest einer Biozidschicht.A filter medium having a biocidal effect for filtering air for an interior of a vehicle consists of at least one filter layer and at least one biocide layer.
Erfindungsgemäß umfasst die Biozidschicht Mikrokapseln, welche aus zumindest einem Polymer ausgebildet sind, wobei auf und/oder in den Mikrokapseln zumindest ein Biozid gespeichert ist.According to the invention, the biocide layer comprises microcapsules which are formed from at least one polymer, at least one biocide being stored on and / or in the microcapsules.
Während eines Betriebs des Fahrzeugs kann bei aus dem Stand der Technik bekannten Filtermedien nach einiger Zeit eine biologische Belastung entstehen, zum Beispiel eine Bakterienbelastung und/oder eine Schimmelpilzbelastung. Diese Bakterien und/oder Schimmelpilze erzeugen unangenehme Gerüche in Form von so genannten microbial volatile organic components (MVOC), d. h. in Form von flüchtigen organischen Verbindungen. Zudem können bei Fahrzeuginsassen durch diese biologische Belastung auch allergische Reaktionen auftreten. Das erfindungsgemäße Filtermedium reduziert diese biologische Belastung, insbesondere die bakterielle Belastung und/oder Schimmelpilzbelastung. Zudem ist das Filtermedium auf einfache Weise zu wechseln, wenn das Biozid im Filtermedium verbraucht ist, so dass die biozide Wirkung für das Fahrzeug aufrechterhalten wird.During operation of the vehicle, biological stress may be introduced in filter media known from the prior art after some time, for example a bacterial load and / or a mold attack. These bacteria and / or molds produce unpleasant odors in the form of so-called microbial volatile organic components (MVOC), d. H. in the form of volatile organic compounds. In addition, allergic reactions may also occur in the vehicle occupant due to this biological stress. The filter medium according to the invention reduces this biological load, in particular the bacterial load and / or mold contamination. In addition, the filter medium is easy to change when the biocide in the filter medium is consumed, so that the biocidal effect is maintained for the vehicle.
Die Mikrokapseln auf Kunststoffbasis, genauer gesagt auf Polymerbasis, ermöglichen durch die Beladung mit Biozid eine kontinuierliche, langsame Abgabe des Biozids, die eine konstante Beseitigung von Mikroorganismen im Filtermedium und in einem durch das Filtermedium gefilterten Luftstrom ermöglicht, d. h. eine Reduzierung der biologischen Belastung, insbesondere der Bakterienbelastung und/oder einer Schimmelpilzbelastung, da das Biozid mikrobielle Substanzen zentral am Filtermedium hemmt. Dadurch tritt aufgrund der verminderten biologischen Belastung keine störende Geruchsentwicklung auf und ein Risiko allergischer Reaktionen der Fahrzeuginsassen aufgrund biologischer Belastung ist reduziert. Das Filtermedium ist beispielsweise als Filter einer Klimatisierungsvorrichtung des Fahrzeugs einsetzbar.The plastic-based microcapsules, more specifically polymer-based, allow biocide loading to provide a continuous, slow delivery of the biocide that allows for constant removal of microorganisms in the filter media and in a stream of air filtered through the filter media, ie, a reduction in biological stress, particularly the bacterial load and / or a mold contamination, since the biocide inhibits microbial substances centrally on the filter medium. As a result, no disturbing odor development occurs due to the reduced biological load and a risk of allergic reactions of the vehicle occupants due to biological stress is reduced. The filter medium can be used for example as a filter of an air conditioning device of the vehicle.
