Definitions
- Antimicrobial protective layer substrate having the antimicrobial protective layer and method of making the substrate having the antimicrobial protective layer
- the invention relates to an antimicrobial protective layer and a substrate with the antimicrobial protective layer.
- a method for producing the substrate with the antimicrobial protective layer is presented.
- a substrate can be any substrate material such as plastic, metal, or ceramic.
- a substrate surface of the substrate is often provided with an antimicrobial protective layer in order to prevent bacteria, viruses or other micro-organisms from adhering to the substrate surface.
- the antimicrobial protective layer has a bactericidal, virucidal and/or fungicidal effect, for example.
- One component of the antimicrobial protective layer is, for example, antimicrobial manganese dioxide (MnO 2 , manganese dioxide) which is produced wet-chemically from potassium permanganate (KMn0 4 ) and manganese (II) salts via a redox reaction and applied to the substrate surface (precipitation).
- MnO 2 antimicrobial manganese dioxide
- II manganese salts via a redox reaction and applied to the substrate surface (precipitation).
- the disadvantage of manganese dioxide is its brown to dark brown color. This results in the protective layer coloring of the protective layer also being brown to dark brown. A possible use of such an antimicrobial protective layer is therefore very limited.
- the object of the invention is to show how an antimicrobial protective layer can be put together so that it can be used variably to protect a substrate surface of a substrate with regard to the coloring of the protective layer.
- an antimicrobial protective layer is specified for protecting a substrate surface of a substrate, the protective layer having at least one antimicrobial agent (anti-microbial agent) with a reagent coloring and at least one inert inorganic color pigment with a of the reagent coloring different color pigment coloring and wherein a reagent content of the reagent in the protective layer and a color pigment content of the inorganic color pigment in the protective layer are selected such that a protection - Layer coloring of the protection layer differs from the reagent coloring.
- the protective layer has a protective layer thickness selected from the range from 0.5 gm to 20 gm and in particular from the range from 1 gm to 10 gm.
- the protective layer coloring is a mixture (mixed color) of the reagent coloring (color of the reagent) and the color pigment coloring (color of the color pigment).
- the antimicrobial effect of the antimicrobial reagent and thus the antimicrobial effect of the protective layer are retained.
- the protective layer has an antibacterial and/or antiviral effect.
- the protective layer ensures that bacteria and/or viruses are killed or cannot or only very poorly adhere to the substrate surface. At the same time, the coloring of the protective layer can be adjusted as desired.
- the inorganic color pigment is inert. That is, it does not affect the antimicrobial effectiveness of the antimicrobial reagent. Likewise, the inorganic color pigment in the production process does not impair application of the antimicrobial reagent or the antimicrobial protective layer to the substrate surface or to an initial substrate surface of an initial substrate. A coatability (applicability) of the protective layer on the substrate surface or starting substrate surface is retained.
- a substrate with the protective layer for protecting a substrate surface of the substrate is also specified.
- the substrate can be any object with a surface to be protected.
- the object is, for example, an object of a means of public transport or an object of an infrastructure facility that is used by several people (e.g.
- a method for producing the substrate with the protective layer is specified with the following method steps: a) providing a starting substrate with a starting substrate surface and b) arranging the protective layer on the starting substrate - Surface .
- the protective layer has a further, colour-neutral, antimicrobial reagent.
- the additional antimicrobial reagent improves the antimicrobial effect of the protective layer. Since the additional antimicrobial reagent is color-neutral, it contributes little or nothing to the color of the protective layer.
- the coloring of the protective layer is not essentially characterized by a coloring of the further color-neutral antimicrobial reagent.
- Elementary silver (Ag) in particular is used as a further, colour-neutral, antimicrobial reagent.
- the antimicrobial reagent preferably has an antimicrobial metal oxide compound.
- an antimicrobial metal oxide compound is titanium dioxide (T1O 2 ) .

Antimikrobielle Schutz-Schicht, Substrat mit der antimikrobiellen Schutz-Schicht und Verfahren zum Herstellen des Substrats mit der antimikrobiellen Schutz-Schicht Antimicrobial protective layer, substrate having the antimicrobial protective layer and method of making the substrate having the antimicrobial protective layer
Die Erfindung betrifft eine antimikrobielle Schutz-Schicht und ein Substrat mit der antimikrobiellen Schutz-Schicht. Darüber hinaus wird ein Verfahren zum Herstellen des Substrats mit der antimikrobiellen Schutz-Schicht vorgestellt . The invention relates to an antimicrobial protective layer and a substrate with the antimicrobial protective layer. In addition, a method for producing the substrate with the antimicrobial protective layer is presented.
Ein Substrat kann aus einem beliebigen Substrat-Material wie Kunststoff, Metall oder Keramik bestehen. Eine Substrat- Oberfläche des Substrats wird oftmals mit einer antimikrobiellen Schutz-Schicht versehen, um ein Anhaften von Bakterien, Viren oder anderer Mikro-Organismen auf der Substrat-Oberfläche zu verhindern. Die antimikrobielle Schutz-Schicht wirkt dazu beispielsweise bakterizid, viruzid und/oder fungizid. A substrate can be any substrate material such as plastic, metal, or ceramic. A substrate surface of the substrate is often provided with an antimicrobial protective layer in order to prevent bacteria, viruses or other micro-organisms from adhering to the substrate surface. For this purpose, the antimicrobial protective layer has a bactericidal, virucidal and/or fungicidal effect, for example.
Ein Bestandteil der antimikrobiellen Schutz-Schicht ist beispielweise antimikrobiell wirkendes Mangan-Dioxid (MnÜ2) , Braunstein) das nasschemisch aus Kaliumpermanganat (KMn04 ) und Mangan (II)-Salzen über eine Redox-Reaktion erzeugt und auf die Substrat-Oberfläche aufgebracht wird (Präzipation). Nachteil des Mangan-Dioxids ist seine braune bis dunkelbraune Farbe. Dies führt dazu, dass die Schutz-Schicht-Färbung der Schutz-Schicht ebenfalls braun bis dunkelbraun ist. Eine Einsatz-Möglichkeit einer solchen antimikrobiellen Schutz- Schicht ist daher sehr eingeschränkt. One component of the antimicrobial protective layer is, for example, antimicrobial manganese dioxide (MnO 2 , manganese dioxide) which is produced wet-chemically from potassium permanganate (KMn0 4 ) and manganese (II) salts via a redox reaction and applied to the substrate surface (precipitation). The disadvantage of manganese dioxide is its brown to dark brown color. This results in the protective layer coloring of the protective layer also being brown to dark brown. A possible use of such an antimicrobial protective layer is therefore very limited.
Aufgabe der Erfindung ist es, aufzuzeigen, wie eine antimikrobielle Schutz-Schicht zusammengesetzt werden kann, damit sie zum Schutz einer Substrat-Oberfläche eines Substrats im Hinblick auf die Färbung der Schutz-Schicht variabel eingesetzt werden kann.
Zur Lösung der Aufgabe wird eine antimikrobielle Schutz schicht zum Schutz einer Substrat-Oberfläche eines Substrats angegeben, wobei die Schutz-Schicht mindestens ein antimikrobiell wirkendes Reagenz (anti-microbial agent) mit einer Reagenz-Färbung und mindestens ein inertes anorganisches Farb-Pigment mit einer von der Reagenz-Färbung verschiedenen Färb-Pigment-Färbung aufweist und wobei ein Reagenz-Gehalt des Reagenz in der Schutz-Schicht und ein Färb-Pigment-Gehalt des anorganischen Färb-Pigments in der Schutz-Schicht derart gewählt sind, dass sich eine Schutz- Schicht-Färbung der Schutz-Schicht von der Reagenz-Färbung unterscheidet . Gemäß einer besonderen Ausgestaltung weist die Schutz-Schicht eine aus dem Bereich von 0,5 gm bis 20 gm und insbesondere eine aus dem Bereich von 1 gm bis 10 gm ausgewählte Schutz-Schicht-Dicke auf. The object of the invention is to show how an antimicrobial protective layer can be put together so that it can be used variably to protect a substrate surface of a substrate with regard to the coloring of the protective layer. To solve the problem, an antimicrobial protective layer is specified for protecting a substrate surface of a substrate, the protective layer having at least one antimicrobial agent (anti-microbial agent) with a reagent coloring and at least one inert inorganic color pigment with a of the reagent coloring different color pigment coloring and wherein a reagent content of the reagent in the protective layer and a color pigment content of the inorganic color pigment in the protective layer are selected such that a protection - Layer coloring of the protection layer differs from the reagent coloring. According to a particular embodiment, the protective layer has a protective layer thickness selected from the range from 0.5 gm to 20 gm and in particular from the range from 1 gm to 10 gm.
Die Schutz-Schicht-Färbung (Farbe der Schutz-Schicht) ist eine Mischung (Misch-Farbe) der Reagenz-Färbung (Farbe des Reagenz) und der Färb-Pigment-Färbung (Farbe des Farb pigments) . Dabei bleibt die antimikrobielle Wirkung des antimikrobiell wirkenden Reagenz und damit die antimikrobielle Wirkung der Schutz-Schicht erhalten. Die Schutz-Schicht wirkt antibakteriell und/oder antiviral. Die Schutz-Schicht sorgt dafür, dass Bakterien und/oder Viren abgetötet werden bzw. nicht oder nur sehr schlecht an der Substrat-Oberfläche anhaften können. Gleichzeitig kann die Färbung der Schutz-Schicht beliebig eingestellt werden. The protective layer coloring (color of the protective layer) is a mixture (mixed color) of the reagent coloring (color of the reagent) and the color pigment coloring (color of the color pigment). The antimicrobial effect of the antimicrobial reagent and thus the antimicrobial effect of the protective layer are retained. The protective layer has an antibacterial and/or antiviral effect. The protective layer ensures that bacteria and/or viruses are killed or cannot or only very poorly adhere to the substrate surface. At the same time, the coloring of the protective layer can be adjusted as desired.
Das anorganische Farb-Pigment ist inert. D.h. es beeinträchtigt die antimikrobielle Wirksamkeit des antimikrobiellen Reagenz nicht. Ebenfalls beeinträchtigt das anorganische Farb-Pigment im Herstell-Verfahren ein Aufträgen des antimikrobiellen Reagenz bzw. der antimikrobiellen Schutz-Schicht auf die Substrat-Oberfläche bzw. auf eine Ausgangs-Substrat-Oberfläche eines Ausgangs-Substrats nicht. Eine Auftragbarkeit (Applizierbarkeit) der Schutz-Schicht auf die Substrat-Oberfläche bzw. Ausgangs-Substrat-Oberfläche bleibt erhalten.
Zur Lösung der Aufgabe wird auch ein Substrat mit der Schutz schicht zum Schutz einer Substrat-Oberfläche des Substrats angegeben. Das Substrat kann ein beliebiger Gegenstand mit einer zu schützenden Oberfläche sein. Der Gegenstand ist beispielsweise ein Gegenstand eines öffentlichen Transportmittels oder ein Gegenstand einer Infrastruktur- Einrichtung, die von mehreren Personen genutzt wird (z.B.The inorganic color pigment is inert. That is, it does not affect the antimicrobial effectiveness of the antimicrobial reagent. Likewise, the inorganic color pigment in the production process does not impair application of the antimicrobial reagent or the antimicrobial protective layer to the substrate surface or to an initial substrate surface of an initial substrate. A coatability (applicability) of the protective layer on the substrate surface or starting substrate surface is retained. To solve the problem, a substrate with the protective layer for protecting a substrate surface of the substrate is also specified. The substrate can be any object with a surface to be protected. The object is, for example, an object of a means of public transport or an object of an infrastructure facility that is used by several people (e.g
Netzwerk-Drucker, Schreibtisch eines Großraum-Büros, etc.). network printer, desk in an open-plan office, etc.).
Gemäß einem weiteren Aspekt der Erfindung wird ein Verfahren zum Herstellen des Substrats mit der Schutz-Schicht mit folgenden Verfahrensschritten angegeben: a) Bereitstellen eines Ausgangs-Substrats mit einer Ausgangs- Substrat-Oberfläche und b) Anordnen der Schutz-Schicht an der Ausgangs-Substrat- Oberfläche . According to a further aspect of the invention, a method for producing the substrate with the protective layer is specified with the following method steps: a) providing a starting substrate with a starting substrate surface and b) arranging the protective layer on the starting substrate - Surface .
In einer besonderen Ausgestaltung weist die Schutz-Schicht ein weiteres, farbneutrales antimikrobiell wirkendes Reagenz auf. Das weitere antimikrobiell wirkende Reagenz verbessert die antimikrobielle Wirkung der Schutzschicht. Da das weitere antimikrobiell wirkende Reagenz farbneutral ist, trägt es nicht bzw. nahezu nicht zur Farbe der Schutz-Schicht bei. Die Schutz-Schicht-Färbung ist nicht wesentlich von einer Färbung des Weiteren, farbneutralen antimikrobiell wirkenden Reagenz geprägt. Als weiteres, farbneutrales antimikrobiell wirkendes Reagenz kommt insbesondere elementares Silber (Ag) zum Einsatz. In a special embodiment, the protective layer has a further, colour-neutral, antimicrobial reagent. The additional antimicrobial reagent improves the antimicrobial effect of the protective layer. Since the additional antimicrobial reagent is color-neutral, it contributes little or nothing to the color of the protective layer. The coloring of the protective layer is not essentially characterized by a coloring of the further color-neutral antimicrobial reagent. Elementary silver (Ag) in particular is used as a further, colour-neutral, antimicrobial reagent.
Vorzugsweise weist das antimikrobiell wirkende Reagenz eine antimikrobiell wirkende Metall-Oxid-Verbindung auf. Ein Beispiel dafür ist Titandioxid (T1O2 ) . Insbesondere ist die antimikrobiell wirkende Metall-Oxid-Verbindung Mangen-Dioxid (Braunstein, MnÜ2 ) . The antimicrobial reagent preferably has an antimicrobial metal oxide compound. An example of this is titanium dioxide (T1O 2 ) . In particular, the metal-oxide compound with an antimicrobial effect is manganese dioxide (manganese dioxide, MnO 2 ) .
Die antimikrobiellen Eigenschaften des Mangan-Dioxids sind daher so interessant, weil Mangan-Dioxid mit Silber, das ebenfalls als antimikrobielles Reagenz wirkt, aus Sauerstoff
und Feuchtigkeit der Luft (Wasser) Sauerstoff-Radikale bildet, die auch als ROS (= reactive oxygen species oder reaktive Sauerstoffspezies) bekannt sind. Diese äußert reaktive Sauerstoffspezies können Proteine, Lipide, RNA oder DNA, aus denen Bakterien und Viren bestehen, derart zerstören, indem sie mit diesen eine chemische Reaktion eingehen und damit Bakterien und Viren unschädlich machen. The antimicrobial properties of manganese dioxide are so interesting because manganese dioxide with silver, which also acts as an antimicrobial agent, from oxygen and moisture in the air (water) forms oxygen radicals, also known as ROS (= reactive oxygen species). These extremely reactive oxygen species can destroy proteins, lipids, RNA or DNA that bacteria and viruses are made of by entering into a chemical reaction with them and thus rendering bacteria and viruses harmless.
Das inerte anorganische Farb-Pigment weist vorzugsweise mindestens eine Metall-Oxid-Verbindung und/oder eine Metall- Hydroxid-Verbindung auf. In einer besonderen Ausgestaltung kann das inerte anorganische Farb-Pigment mindestens einem aus der Gruppe Baddelyit, Granat, inverser Spinell,The inert inorganic color pigment preferably has at least one metal oxide compound and/or one metal hydroxide compound. In a particular embodiment, the inert inorganic color pigment can be at least one from the group baddelyite, garnet, inverse spinel,
Kassiterit, Korund, Olivin, Perovskit, Phenakit, Rutil, Silikat, Sphen (Titanit), Spinell, Stannat und Zirkon (Zirkonat-Silikat) ausgewählten Kristall-Struktur-Typen zugeordnet werden. Cassiterite, corundum, olivine, perovskite, phenakite, rutile, silicate, sphene (titanite), spinel, stannate and zircon (zirconate silicate) are assigned to selected crystal structure types.
Je nach Farbe des anorganischen Färb-Pigments wird die braune Farbe des Mangan-Dioxids aufgehellt, rotbraun, grau, ockerbraun oder oliv- bis lind-grün, so dass eine entsprechende Schutz-Schicht-Färbung entsteht. Depending on the color of the inorganic coloring pigment, the brown color of the manganese dioxide is lightened, reddish brown, grey, ocher brown or olive to lime green, so that a corresponding protective layer color is created.

Beim chemischen Sprüh-Verfahren wird durch das Aufsprühen der Bestend-Teile wenigstens eine chemische Reaktion initiiert. Es kommt während/und oder nach dem Aufsprühen zu einer chemischen Reaktion (z.B. durch Einwirken von thermischer Energie während oder nach dem Aufsprühen). Beispielsweise wird durch das chemische Sprüh-Verfahren die Schutz-Schicht und/oder mindestens ein Bestand-Teil der Schutz-Schicht auf der Ausgangs-Substrat-Oberfläche parzipitiert . Die Schutz-Schicht bzw. der Bestand-Teil der Schutz-Schicht werden durch das chemische Sprüh-Verfahren als Parzipitat aufgetragen. With regard to the method, a spraying method using at least one spray nozzle for spraying on at least one component is used in particular for arranging the protective layer Part of the protective layer and / or carried out for spraying at least one starting substance of at least one component of the protective layer. A chemical spraying method is preferably used as the spraying method (spray method). In the chemical spray process, at least one chemical reaction is initiated by spraying on the components. A chemical reaction occurs during/and after spraying (e.g. due to the effect of thermal energy during or after spraying). For example, the protective layer and/or at least a constituent part of the protective layer is precipitated on the starting substrate surface by the chemical spraying method. The protective layer or the component part of the protective layer is applied as a precipitate by the chemical spray method.
Der Bestand-Teil und/oder die Ausgangs-Substanz des Bestandteils (gemäß dem Sprüh-Verfahren) sind vorzugweise aus der Gruppe antimikrobiell wirkendes Reagenz, Ausgangs- Substanz des antimikrobiell wirkenden Reagenz, weiteres, antimikrobiell wirkendes Reagenz, Ausgangs-Substanz des weiteren antimikrobiell wirkenden Reagenz, anorganisches Farb-Pigment und Ausgangs-Substanz des anorganischen Farb pigments ausgewählt. The component part and/or the starting substance of the component (according to the spray method) are preferably from the group of antimicrobial reagent, starting substance of the antimicrobial reagent, further antimicrobial reagent, starting substance of the further antimicrobial agent Reagent, inorganic color pigment and starting substance of the inorganic color pigment selected.
Zur Verbesserung des Verfahrens werden vor, während oder nach dem Anordnen der Schutz-Schicht das Substrat, die Substrat- Oberfläche, das Ausgangs-Substrat, die Ausgangs-Substrat- Oberfläche oder die Ausgangs-Schutz-Schicht erwärmt. Insbesondere wird daher zum Anordnen der Schutz-Schicht thermische Energie mit Hilfe einer Wärme-Quelle eingeleitet. Die Wärme-Quelle kann dabei beliebig sein, z.B. eine Quelle für Infrarot-Strahlung. To improve the method, the substrate, the substrate surface, the starting substrate, the starting substrate surface or the starting protective layer are heated before, during or after the arrangement of the protective layer. In particular, thermal energy is therefore introduced with the aid of a heat source in order to arrange the protective layer. The heat source can be any, e.g. a source of infrared radiation.
Gemäß einer besonderen Ausgestaltung wird zum Verfahren für das Beschichten eines flexiblen Substrats eine Rolle-zu- Rolle-Vorrichtung verwendet. Das Verfahren ist als Rolle-zu- Rolle-Verfahren (roll-to-roll, R2R) ausgebildet. Hierfür wird
das sich auf einer Transport-Rolle befindliche unbeschichtete Substrat abgerollt, bearbeitet und schließlich als fertiges, mit der Schutz-Schicht versehenes Substrat auf eine weitere Transport-Rolle aufgerollt. Auf diese Weise kann das Substrat automatisiert und kostengünstig hergestellt werden. According to a particular embodiment, a roll-to-roll device is used for the method for coating a flexible substrate. The method is designed as a roll-to-roll method (roll-to-roll, R2R). For this will the uncoated substrate on a transport roller is unrolled, processed and finally rolled onto another transport roller as a finished substrate provided with the protective layer. In this way, the substrate can be manufactured in an automated and cost-effective manner.
Zusammenfassend sind mit der Erfindung folgende Vorteile verbunden : In summary, the following advantages are associated with the invention:
- Durch den Einsatz von Färb-Pigmenten kann das antimikrobiell wirkende, braune Mangan-Dioxid(-Silber)-System der Schutz-Schicht auf sichtbaren Oberflächen wie Mund- Nasenschutzmasken angewandt werden. - Through the use of color pigments, the antimicrobial, brown manganese dioxide (silver) system of the protective layer can be applied to visible surfaces such as mouth and nose protection masks.
- Bedienelemente diverser Medizingeräte (beispielsweise Computertomographen, Kernspintomographen oder Röntgenanlagen) bzw. deren Oberflächen lassen sich optisch ansehnlich mit dem Mangan-Dioxid (-Silber)-System und den anorganischen Farb pigmenten keimfrei gestalten. - Operating elements of various medical devices (e.g. computer tomographs, magnetic resonance tomographs or X-ray systems) or their surfaces can be made germ-free with the manganese dioxide (silver) system and the inorganic color pigments.
- Kontaktflächen in Gebäuden und Transportmitteln (beispielsweise Züge, Flugzeuge und Autobusse) mit viel Publikumsverkehr können mit farbigen Schutz-Schichten vor Keimen geschützt werden. - Contact surfaces in buildings and means of transport (e.g. trains, airplanes and buses) with a lot of public traffic can be protected against germs with colored protective layers.
- Wenn Silber und Mangan-Dioxid durch ein chemisches Sprüh- Verfahren aufgetragen werden, entstehen braune bis dunkelbraune Flecken. Diese Flecken können durch die Zugabe von anorganischen Färb-Pigmenten abgemildert oder mit Hilfe einer Mischfarbe überdeckt werden. Die Färb-Pigmente werden den jeweiligen reaktiven Spritzmedien zugesetzt. Bei den anorganischen Färb-Pigmenten handelt es sich vorzugsweise um chemisch und energetisch sehr stabile Oxide und Silikate, die in Wasser, Säuren und Laugen unlöslich sind. Da diese Farb pigmente chemisch sehr inert sind, nehmen sie an den chemischen Reaktionen des reaktiven Sprüh-Verfahrens nicht teil. Sie sorgen nur für eine optisch ansehnliche Oberfläche. Ein weiterer technischer Vorteil dieser Färb-Pigmente ist,
dass sie aufgrund ihrer chemischen Struktur (freie Elektronenpaare im Sauerstoff-Anteil des Oxids) für eine bessere Anhaftung des Silber/Mangan-Dioxid- Systems auf den Oberflächen sorgen. - When silver and manganese dioxide are applied by a chemical spray process, brown to dark brown stains are produced. These stains can be softened by adding inorganic color pigments or covered with a mixed color. The color pigments are added to the respective reactive spray media. The inorganic color pigments are preferably chemically and energetically very stable oxides and silicates that are insoluble in water, acids and alkalis. Since these color pigments are chemically very inert, they do not take part in the chemical reactions of the reactive spraying process. They only provide a visually attractive surface. Another technical advantage of these coloring pigments is that due to their chemical structure (free pairs of electrons in the oxygen portion of the oxide) they ensure better adhesion of the silver/manganese dioxide system to the surfaces.
- In öffentlichen Transportmitteln wie Züge lassen sich die Kontaktflächen, die Fahrgäste berühren, durch antimikrobiell wirkende Schichten schützen. Das gilt insbesondere auch für den sanitären Bereich in den öffentlichen Transportmitteln. - In public transport such as trains, the contact surfaces that passengers touch can be protected by antimicrobial layers. This applies in particular to the sanitary area in public transport.
- Das gleiche gilt auch für die Infrastruktur von Gebäuden (sanitäre Anlagen, Fahrstühle, Treppengelände, Sitzgelegenheiten, Schreibtische, Türklinken etc.) mit viel Publikumsverkehr . - The same applies to the infrastructure of buildings (sanitary facilities, elevators, stairwells, seating, desks, door handles, etc.) with a lot of public traffic.
- Bedienelemente diverser Medizingeräte (Computertomographen, Kernspintomographen, Röntgenanlagen) sowie deren Oberflächen, mit denen ein Patient in Berührung kommen kann, können zur Keimfreiheit mit der antimikrobiellen wirkenden Schutz schicht versehen werden. - Operating elements of various medical devices (computer tomographs, magnetic resonance tomographs, X-ray systems) and their surfaces that a patient can come into contact with can be provided with the antimicrobial protective layer to ensure sterility.

Das Ausführungsbeispiel bezieht sich auf eine antimikrobielle Schutz-Schicht 1 zum Schutz einer Substrat-Oberfläche 110 eines Substrats 100, wobei die Schutz-Schicht 1 Figure 2C shows a roll-to-roll device that can be used with the method. The exemplary embodiment relates to an antimicrobial protective layer 1 for protecting a substrate surface 110 of a substrate 100, the protective layer 1
- mindestens ein antimikrobiell wirkendes Reagenz 11 mit einer Reagenz-Färbung 110 und - At least one antimicrobial reagent 11 with a reagent color 110 and
- mindestens ein inertes anorganisches Farb-Pigment 12 mit einer von der Reagenz-Färbung 110 verschiedenen Färb-Pigment- Färbung 120 aufweist und wobei - Has at least one inert inorganic color pigment 12 with a color pigment coloration 120 different from the reagent coloration 110 and wherein
- ein Reagenz-Gehalt 111 des Reagenz 11 in der Schutz-Schicht 1 und ein Färb-Pigment-Gehalt 121 des anorganischen Farb pigments 12 in der Schutz-Schicht 1 derart gewählt sind, dass sich eine Schutz-Schicht-Färbung 10 der Schutz-Schicht 1 von der Reagenz-Färbung 110 unterscheidet. - A reagent content 111 of the reagent 11 in the protective layer 1 and a color pigment content 121 of the inorganic color pigment 12 in the protective layer 1 are selected such that a protective layer coloring 10 of the protective Layer 1 differs from reagent stain 110.
Das antimikrobiell wirkende Reagenz ist MnÜ2. Der Gehalt an MnÜ2 in der Schutz-Schicht beträgt etwa 30 bis 50 Gew.% bezogen auf die reine AgMn02-Schicht. Neben Mn02 ist in der Schutz-Schicht elementares Silber als weiteres, farbneutrales antimikrobiell wirkendes Reagenz 13 vorhanden. Der Gehalt an elementarem Silber beträgt etwa 25 bis 50 Gew.% bezogen auf die reine AgMn02-Schicht. The antimicrobial reagent is MnÜ2. The MnÜ2 content in the protective layer is about 30 to 50% by weight, based on the pure AgMnO 2 layer. In addition to MnO 2 , elementary silver is present in the protective layer as a further, color-neutral, antimicrobial reagent 13 . The elemental silver content is about 25 to 50% by weight, based on the pure AgMn0 2 layer.
Das inerte anorganische Farb-Pigment ist eines der zuvor genannten Färb-Pigmente mit blauer, roter, gelber, grüner oder weißer Farb-Pigment-Färbung. The inert inorganic color pigment is one of the aforementioned color pigments with blue, red, yellow, green or white color pigment coloring.
Das Substrat 100 weist faserförmiges Substrat-Material 102 mit Cellulose auf. Das Substrat besteht aus einem flexiblen Vliesstoff . Die beschichtete Substrat-Oberfläche wird von Cellulose-Fasern gebildet. The substrate 100 comprises fibrous substrate material 102 with cellulosic. The substrate consists of a flexible non-woven fabric. The coated substrate surface is made of cellulose fibers.
Die Schutz-Schicht-Dicke 14 der anti-mikrobiellen Schutz- Schicht beträgt ca. 5 gm. In einer alternativen Ausgestaltung beträgt die Schutz-Schicht-Dicke 10 gm. The protective layer thickness 14 of the antimicrobial protective layer is approximately 5 μm. In an alternative embodiment, the protective layer thickness is 10 μm.
Zum Herstellen des Substrats 100 werden folgende Verfahrens- Schritte durchgeführt:
a) Bereitstellen 2002 eines Ausgangs-Substrats 1000 (mit den Cellulose-Fasern) mit einer Ausgangs-Substrat-Oberfläche 1100 und b) Anordnen 2002 der Schutz-Schicht 1 an der Ausgangs- Substrat-Oberfläche 1100. The following method steps are carried out to produce the substrate 100: a) Providing 2002 an initial substrate 1000 (with the cellulose fibers) with an initial substrate surface 1100 and b) arranging 2002 the protective layer 1 on the initial substrate surface 1100.
Zum Anordnen 2002 der Schutz-Schicht 1 wird ein Sprüh- Verfahren durchgeführt. Dazu wird mindestens eine Spritz-Düse 1200 zum Aufsprühen mindestens eines Bestand-Teils der Schutz-Schicht und/oder zum Aufsprühen mindestens einer Ausgangs-Substanz mindestens eines Bestandteils der Schutz schicht eingesetzt. Das Sprüh-Verfahren ist als chemisches Sprüh-Verfahren ausgestaltet. Dazu wird nach dem Aufsprühen thermische Energie mit Hilfe einer Wärme-Quelle 1300 in die Schutz-Schicht bzw. in das Substrat eingeleitet. For arranging 2002 the protection layer 1, a spraying process is performed. For this purpose, at least one spray nozzle 1200 is used for spraying on at least one component of the protective layer and/or for spraying on at least one starting substance of at least one component of the protective layer. The spraying process is designed as a chemical spraying process. For this purpose, after the spraying, thermal energy is introduced into the protective layer or into the substrate with the aid of a heat source 1300 .
Da das Substrat flexibel ist, kann hier eine Rolle-zu-Rolle- Vorrichtung 1400 angewendet wird. Es wird ein Rolle-zu-Rolle (Roll-to-Roll)-Verfahren eingesetzt. Hierfür wird das sich auf einer Transport-Rolle 1401 befindliche unbeschichtete Substrat 1000 abgerollt, bearbeitet und als fertiges, mit der Schutz-Schicht beschichtetes Substrat 100 auf eine weitere Transport-Rolle 1402 wieder aufgerollt. Because the substrate is flexible, a roll-to-roll device 1400 can be used here. A roll-to-roll process is used. For this purpose, the uncoated substrate 1000 located on a transport roller 1401 is unrolled, processed and rolled up again onto a further transport roller 1402 as a finished substrate 100 coated with the protective layer.
In dem Roll-to-Roll- Verfahren wird über das chemisches Sprüh-Verfahren mit spezieller Düsentechnik die antimikrobiell wirkenden Reagenzien auf die Substrat- Oberfläche aufgebracht. In the roll-to-roll process, the antimicrobial reagents are applied to the substrate surface using the chemical spray process with special nozzle technology.
Im chemischen Sprüh-Verfahren wird das verwendete Mangan- Dioxid aus einer Kalium-Permanganat-Lösung und einer Lösung aus Mangan (II)-Nitrat oder Mangan (II)-Acetat hergestellt. Vor der Reaktion der beiden Lösungen wird die Mangan (II)-Nitrat oder die Mangan (II)-Acetat- Lösung auf pH 8 (basisch) eingestellt . Dies geschieht entweder durch Zugabe von Ammoniak bzw. Ammoniumchlorid oder durch Zugabe einer basisch wirkenden Aminosäure wie L-Lysin. Alternativ werden andere basische Aminosäuren wie L-Histidin oder L-Arginin verwendet.
Die Kalium-Permanganat-Lösung und die basische Mangan (II)— Salz-Lösung werden getrennt über zwei Düsen simultan auf die zu beschichtende Substrat-Oberfläche gespritzt. In dem Moment, in dem die beiden Lösungen aufeinandertreffen, wird das Mangan-Dioxid gebildet und schlägt sich als Präzipitat auf die zu beschichtende Substrat-Oberfläche nieder. In the chemical spray process, the manganese dioxide used is produced from a potassium permanganate solution and a solution of manganese (II) nitrate or manganese (II) acetate. Before the two solutions react, the manganese (II) nitrate or the manganese (II) acetate solution is adjusted to pH 8 (basic). This is done either by adding ammonia or ammonium chloride or by adding a basic amino acid such as L-lysine. Alternatively, other basic amino acids such as L-histidine or L-arginine are used. The potassium permanganate solution and the basic manganese (II) salt solution are sprayed separately via two nozzles simultaneously onto the substrate surface to be coated. The moment the two solutions meet, manganese dioxide is formed and forms a precipitate on the substrate surface to be coated.
Über eine Komproportionierung (Spezialfall einer Redoxreaktion) bildet sich aus Mn+7 und Mn+2 Braunstein. Bei der Reaktion wird das Mangan (II)-Salz vom Kalium-Permanganat zu Mangan (IV)-Oxid oxidiert und das Kalium-Permanganat wird vom Mangan (II)-Salz zu Mangan (IV)-Oxid reduziert. Das Mangan (IV)-Oxid stammt sowohl aus dem Reduktionsmittel als auch aus dem Oxidationsmittel. Das Reduktionsmittel und das Oxidationsmittel dienen also als Ausgangs-Substanzen von Mangan-Dioxid . Manganese dioxide is formed from Mn +7 and Mn +2 via comproportionation (a special case of a redox reaction). In the reaction, the manganese(II) salt is oxidized by the potassium permanganate to manganese(IV) oxide and the potassium permanganate is reduced by the manganese(II) salt to manganese(IV) oxide. The manganese (IV) oxide originates from both the reducing agent and the oxidizing agent. The reducing agent and the oxidizing agent thus serve as starting substances for manganese dioxide.
Zur Beschleunigung der chemischen Reaktion wird die Ausgangs- Substrat-Oberfläche mit der aufgebrachten Ausgangs- Schutzschicht durch eine geeignete Wärme-Quelle 1300 beheizt. To accelerate the chemical reaction, the initial substrate surface with the initial protective layer applied is heated by a suitable heat source 1300 .
Zur Abmilderung der braunen Farbe des Mangan-Dioxids werden in beiden Lösungen, also sowohl in der Kalium-Permanganat- Lösung als auch in der Mangan (II)-Salz-Lösung anorganische Färb-Pigmente suspendiert. Dabei können die Färb-Pigmente von gleicher oder unterschiedlicher chemischer Zusammensetzung sein. Diese Färb-Pigmente werden dann mit den beiden Reaktanten auf die zu beschichtende Substrat-Oberfläche gespritzt . Dabei verhalten sich die Färb-Pigmente chemisch inert und nehmen an der chemischen Reaktion nicht teil.
To soften the brown color of the manganese dioxide, inorganic color pigments are suspended in both solutions, ie both in the potassium permanganate solution and in the manganese(II) salt solution. The color pigments can be of the same or different chemical composition. These color pigments are then sprayed with the two reactants onto the substrate surface to be coated. The color pigments are chemically inert and do not take part in the chemical reaction.
