Abstract
Description
Die Erfindung betrifft eine Beschichtung zum Aufbringen auf ein Substrat, ein Verfahren zum Herstellen der Beschichtung und Verwendungen der Beschichtung. The invention relates to a coating for application to a substrate, a method for Producing the coating and uses of the coating.
Aus dem Stand der Technik sind verschiedene Beschichtungen zum Aufbringen auf ein Substrat bekannt, welche entweder als Bulk oder als Beschichtungswerkstoff eingesetzt werden, um beispielsweise die Reinigungsfähigkeit von Oberflächen zu verbessern. From the prior art are various coatings for application to a Substrate known, which used either as a bulk or as a coating material For example, to improve the cleanability of surfaces.
Hierzu gehören teflonartige Beschichtungen, also Fluorcarbonharze und Derivate hiervon, die ein sehr gutes Antihaftverhalten aufweisen, jedoch auch schlecht an den Substraten haften und zudem eine geringe Abriebfestigkeit aufweisen. Die tribologischen Eigenschaften dieser Fluorcarbonharze sind ebenfalls herausragend. These include Teflon-like coatings, ie fluorocarbon resins and derivatives thereof, the have a very good non-stick behavior, but also adhere poorly to the substrates and also have a low abrasion resistance. The tribological properties of this Fluorocarbon resins are also outstanding.
Weiterhin sind gefüllte Fluorcarbonharze, beispielsweise aus der EP 109 171 B1 bekannt, bei denen die weichen Fluorpolymere, um eine höhere Abriebfestigkeit zu erhalten, mit Metall oder Oxidfüllern im µm-Bereich gefüllt werden, so daß sich die mechanische Verschleißresistenz wesentlich verbessert. Nachteil dieser Technik ist es, daß der organische Fluorcarbonbinder in der Hitze, wie sie z. B. bei Bratpfannenbeschichtungen auftritt, weich, bzw. flüssig wird und damit die Abriebbeständigkeit wesentlich verschlechtert wird, so daß beim Gebrauch die oxidischen Füller aus der Matrix ausgetragen werden. Furthermore, filled fluorocarbon resins, for example known from EP 109 171 B1, at the soft fluoropolymers with metal to obtain a higher abrasion resistance or oxide fillers are filled in the micron range, so that the mechanical Wear resistance significantly improved. Disadvantage of this technique is that the organic Fluorcarbonbinder in the heat, as z. B. occurs in frying-pan coatings, soft, or becomes liquid and thus the abrasion resistance is significantly deteriorated, so that in use, the oxide filler is discharged from the matrix.
Fluorierte Silane, die auf Oberflächen aufgesintert werden, zeigen besonders im keramischen Bereich hohe Abriebfestigkeiten, werden aber beim Gebrauch von Säuren und Laugen sehr schnell chemisch von den Oberflächen abgekoppelt, so daß eine Anwendbarkeit im Küchenbereich bisher nicht bekannt ist. Fluorinated silanes, which are sintered on surfaces, show particularly in the ceramic Range high abrasion resistance, but become very much in the use of acids and alkalis rapidly chemically decoupled from the surfaces so that applicability in the Kitchen area is not known yet.
Sol-Gel-Gradientenmaterialien, wie sie aus der US 5,274,159, der EP 587 667 B1, der DE 196 49 954 A1 und der DE 196 49 955 A1 bekannt sind, zeigen zwar hohe Abriebbeständigkeiten, doch wird auch hier aufgrund der Gradientenstruktur ein chemischer Abtrag festgestellt. Sol-gel gradient materials, as described in US 5,274,159, EP 587 667 B1, the DE 196 49 954 A1 and DE 196 49 955 A1 are known, show high abrasion resistance, but here, too, due to the gradient structure, a chemical erosion is detected.
Zusammenfassend läßt sich also feststellen, daß gemäß dem Stand der Technik entweder die Matrix weich und der Füller hart ist, wobei der Füller sich aus der Matrix ablöst bzw. enthaftet oder aber die Matrix hart ist und es der Beschichtung an chemischer Beständigkeit bzw. an fluorierter Masse fehlt. In summary, it can be stated that according to the prior art either the Soft matrix and the filler is hard, the filler separates from the matrix or or the matrix is hard and the coating of chemical resistance or lack of fluorinated compound.
Aufgabe der Erfindung ist somit die Schaffung einer dauerhaften hitzebeständigen Beschichtung, die sowohl chemikalienbeständig als auch eine hohe Abriebbeständigkeit aufweist. The object of the invention is thus to provide a durable heat resistant Coating that is both chemical resistant and high abrasion resistance having.
Im Rahmen der Erfindung wird dies dadurch erreicht, daß die Beschichtung aus einer anorganischen oder anorganisch-organischen Matrix besteht, die mit fluorierten Partikeln gefüllt ist. In the context of the invention this is achieved in that the coating of a inorganic or inorganic-organic matrix is made with fluorinated particles is filled.
Im Rahmen der Erfindung hat sich überraschend gezeigt, daß durch die Verwendung von anorganischen oder organischen Beschichtungen, die mit fluorierten Partikeln gefüllt sind, eine dauerhafte, hitzebeständige, chemikalienbeständige, auf dem Substrat fest haftende Beschichtung erreicht werden kann. Es handelt sich also um weiche Füller in einer relativ harten Matrix, bei der kein Auslösen oder Aufweichen der Beschichtung bei hoher Temperatur zu beobachten ist und die dennoch sehr abriebbeständig ist. In the context of the invention has surprisingly been found that through the use of inorganic or organic coatings filled with fluorinated particles, a durable, heat-resistant, chemical-resistant, adherent to the substrate Coating can be achieved. So these are soft pens in a relative hard matrix, in which no triggering or softening of the coating at high Temperature is observed and yet very resistant to abrasion.
Der Kontaktwinkel dieser Beschichtungen gegen Wasser beträgt mehr als 60° (>60°), vorzugsweise mehr als 90° (>90°). Die beschriebenen Beschichtungen lassen sich mattieren, füllen oder strukturieren. Im Falle von Oberflächenstrukturierungen im Nano- oder Mikrobereich zeigen diese hydrophoben Schichten Kontaktwinkel gegen Wasser von mehr als 140° und selbstreinigende Eigenschaften. The contact angle of these coatings against water is more than 60 ° (> 60 °), preferably more than 90 ° (> 90 °). The described coatings can be matted, fill or structure. In the case of surface structuring in the nano- or In the micro range, these hydrophobic layers show contact angles to water of more than 140 ° and self-cleaning properties.

Analogously to Example 7, the solution is applied by spraying on an absorbent paper and then dried at 130 ° C for 2 h in a convection oven. You get one Paper surface with dirt-repellent properties. The exam will be a 2% The soot solution was dropped on the surface and observed on the surface for 10 minutes. Then the drop is rinsed off with a stream of water. After the rinsing process are no soot residue on the surface to see. With the untreated paper is after observed an immediate penetration of the soot solution. The stain is with Water not removable.
