Abstract
Description
Die Erfindung betrifft Zusammensetzungen temper- und sinterbarer Überzugsmassen, basierend auf fluor- bzw. fluoridhaltigen Effektstoffen, welche eine Minimierung der Oberflächenenergie bewirken, deren Herstellung und Verwendung.The Invention relates to compositions of temperable and sinterable coating compositions, based on fluorine or fluoride-containing effect substances which cause a minimization of the surface energy whose Manufacture and use.
Üblicherweise werden Keramische Gegenstände an der Oberfläche durch den Auftrag von Glasuren und/oder Engoben veredelt. Diese Überzugsmasse hat dabei sowohl dekorative als auch funktionelle Aufgaben. Glasuren erzeugen im Brand einen dichten Oberflächenfilm wohingegen Engoben (mit eingeschlossen Sinterengoben) in der Regel „atmungsaktive” Schichten ergeben.Usually become ceramic objects on the surface refined by the application of glazes and / or engobes. This coating mass has both decorative and functional tasks. glazes create a dense surface film in fire Engobes (including sintered bottoms) typically "breathable" layers result.
Durch den Auftrag solcher Schutzschichten wird die Keramik beispielsweise gegen chemische Einflüsse, gegen mechanische Belastungen oder partiell gegen thermische Einflüsse geschützt.By the order of such protective layers, the ceramic, for example against chemical influences, against mechanical loads or partially protected against thermal influences.
In
den letzen Jahren wurde immer mehr nach einer Funktionalisierung
der erzeugten Oberflächen gefragt, nicht zu letzt darauf
beruhend, dass durch die Nanotechnologie der sogenannte Easy-To-Clean
Effekt (basierend auf hydrophobierten und/oder oleophobierten Oberflächen)
bekannt wurde. Meist werden in diesen Bereichen Fluorverbindungen
(Fluorsilane, Fluorcarbonharze, Fluoracrylate, ...), Wachse wie
auch Silikon-basierte Materialien beschrieben. In der Regel handelt
es sich um Sol-Gel-Beschichtungen, wie auch
Weitere
bekannte Verfahren (
Ein großer Nachteil aller dieser Verfahren ist, dass sowohl die chemische als auch die mechanische Beständigkeit gering ist. Weiterhin ist mindestens ein, wenn nicht sogar zwei Nachhandlungsschritte im Produktionsprozess notwendig, um eine passable semipermanente Hydrophobierung zu erzeugen.One big disadvantage of all of these methods is that both the chemical as well as the mechanical resistance low is. Furthermore, there is at least one, if not two, post-processing steps necessary in the production process to make a passable semipermanent To produce hydrophobing.
Diesem aufwendigen Prozess könnte entgegengewirkt werden, indem fluor- oder fluoridhaltige Materialien als Glasur oder Engobe (in diesem Dokument unter „Überzugsmassen” zusammengefasst) eingebaut werden und somit das Einbrandbrandverfahren mit permanentem Hydrophob-Effekt ermöglicht wird.this elaborate process could be counteracted by Fluoride or fluoride containing materials as glaze or engobe (in summarized in this document under "coating compositions") be installed and thus the Einbrandbrandverfahren with permanent Hydrophobic effect is enabled.
Solche
Effektstoffe finden bereits bei der Herstellung von Fluorid-Gläsern
Anwendung.
Nachteil dieser Verfahren ist nun wieder, dass die Reaktionstemperaturen und die Inertgasumgebung für den keramischen Brand (zwischen 900°C und 1.450°C, für Baukeramiken, Sanitärkeramik, Porzellan, Steinzeug, Steingut, usw.) nicht geeignet sind.disadvantage This process is now again that the reaction temperatures and the inert gas environment for the ceramic fire (between 900 ° C and 1,450 ° C, for building ceramics, Sanitary ware, porcelain, stoneware, earthenware, etc.) not are suitable.
Aufgabe der Erfindung ist es daher, ein Materialgemenge zu finden, welches Fluor- oder fluorirdhaltige Substanzen beinhaltet, die (auch im oxidierenden) Brand bei der Keramikherstellung in einem Temperaturbereich zwischen 900°C und 1.450°C, eingesetzt werden können, um so die Überzugsmasse direkt und permanent zu hydrophobieren.task The invention is therefore to find a material mixture, which Fluorine or fluorirdhaltige substances includes, which (also in oxidizing) firing in ceramic production in a temperature range between 900 ° C and 1450 ° C, are used can, so the coating mass directly and permanently to hydrophobicize.
Eine weitere Aufgabe der Erfindung ist es, diese Überzugsmasse so zu gestalten, dass neben dem Zweit- oder Drittbrand (Dekorbrand) das gängige Einbrandverfahren genutzt werden kann, um permanent leicht zu reinigende, hydrophobierte keramische Oberflächen zu erzeugen.A Another object of the invention is this coating composition to be designed so that next to the second or third firing (decorative firing) the common penetration process can be used to permanently light to be cleaned, hydrophobic ceramic surfaces produce.
Die der Erfindung zu Grunde liegende Aufgabe wird in einer ersten Ausführungsform gelöst durch eine Zusammensetzung, umfassend temperaturbeständige oder thermisch stabilisierbare Metallfluoride (Hepta-, Hexa-, Penta-, Tetra- sowie Tri- und Bifluoride, deren Kristallwasser- und Oxidreiche Modifikation und Fluorometallate) aber auch durch Hexafluoroaluminate, Tetrafluoroborate, Hexafluorosilikate und andere Fluorokomplexsalze und-sauren, besonders aber durch beständige Tri- und Tetrafluoride wie beispielsweise ZrF4, FiF4, MnF4 oder AlF3. Ganz besonders bevorzugt werden allerdings ZrF4, AlF3 und Bariumfluorid.The object underlying the invention is achieved in a first embodiment by a composition comprising temperature-resistant or thermally stabilizable metal fluorides (hepta-, hexa-, penta-, tetra- and tri- and bifluorides, their crystal water and oxide-rich modification and fluorometalates) but also by hexafluoroaluminates, tetrafluoroborates, hexafluorosilicates and other fluorocomplex salts and acids, but especially by resistant tri- and tetrafluorides such as ZrF 4 , FiF 4 , MnF 4 or AlF 3 . However, ZrF 4 , AlF 3 and barium fluoride are very particularly preferred.
Diese Aufgabe wird also durch die Zusammensetzung mit den Merkmalen des Patentanspruchs 1 gelöst. Bevorzugte Ausgestaltungen der Erfindung sind in den Unteransprüchen angeben.These Task is thus characterized by the composition with the characteristics of Patent claim 1 solved. Preferred embodiments of Invention are specified in the subclaims.
In bereitgestellten Formulierungen für Glasuren und Engoben zeigte sich überraschenderweise ein zusätzlicher positiver Effekt: Durch die Anwesenheit relativ hoher Fluorid-Konzentrationen kann die Menge an Fritte bzw. Fluß minimiert werden.In provided formulations for glazes and engobes Surprisingly, there was an additional one positive effect: due to the presence of relatively high fluoride concentrations the amount of frit or flow can be minimized.
Um einen gut sichtbaren hydrophobierenden Effekt zu erzielen, sollten mindestens 5 Mol% flouridhaltiger Materialien bezogen auf die Gesamtformulierung eingesetzt werden. Es hat sich gezeigt, dass hervorragende Effekte beim Einsatz von 10 Mol% bis 20 Mol% fluoridhaltiger Rohstoffe erreicht werden. Dieser Hydrophob-Effekt kann durch die Zugabe von Boriden oder Nitriden begünstigt werden, insbesondere in Bezug auf das „Reinigungsverhalten” gegenüber heißen Verschmutzungen wie Schlacke, Metallspritzer und ähnlichen Materialien.Around should achieve a well visible hydrophobing effect at least 5 mol% of fluoride-containing materials based on the total formulation be used. It has been shown to have excellent effects achieved with the use of 10 mol% to 20 mol% of fluoride-containing raw materials become. This hydrophobic effect can be achieved by the addition of borides or nitrides are favored, especially in relation on the "cleaning behavior" opposite hot soiling such as slag, metal splashes and similar materials.
Die Hydrophobie kann gut mittels Kontaktwinkelmessungen abgeschätzt werden. Als Kontaktwinkel wird der Winkel bezeichnet, den ein Flüssigkeitstropfen auf der Oberfläche eines Feststoffs zu dieser Oberfläche bildet. Die Größe des Kontaktwinkels zwischen Flüssigkeit und Feststoff hängt ab von der Wechselwirkung zwischen den Stoffen an der Berührungsfläche. Je geringer diese Wechselwirkung ist, desto größer wird der Kontaktwinkel. Aus der Bestimmung der Kontaktwinkel können bestimmte Eigenschaften der Oberfläche eines Feststoffs – wie zum Beispiel die Oberflächenenergie – bestimmt werden. Im Spezialfall der Verwendung von Wasser bezeichnet man bei geringen Kontaktwinkel (ca. 0°) die Oberfläche als hydrophil, bei Winkeln um 90° als hydrophob und bei noch größeren Winkeln als superhydrophob. Letzteres wird bei sehr hohen Winkeln (ca. 160°) auch als Lotuseffekt bezeichnet und entspricht einer extrem geringen Benetzbarkeit.The Hydrophobicity can be estimated well by contact angle measurements become. As the contact angle, the angle is called, which is a drop of liquid on the surface of a solid to this surface forms. The size of the contact angle between Liquid and solid depends on the interaction between the substances at the contact surface. The lower this interaction is, the larger the contact angle becomes. From the determination of the contact angle can certain properties the surface of a solid - such as the surface energy - to be determined. In a special case The use of water is called at low contact angle (about 0 °) the surface as hydrophilic, at angles 90 ° as hydrophobic and even larger Angles as superhydrophobic. The latter is at very high angles (about 160 °) also called lotus effect and corresponds an extremely low wettability.
Der Einsatz von fluor- oder fluoridhaltigen Fritten in Standardglasuren erbringt keine hydrophoben Effekte. In der Regel liegen die Kontaktwinkel dort zwischen 3° und 10°. Durch den Ersatz oxidischer Rohstoffe gegen fluor- oder fluoridhaltigen Materialien in der Überzugsmasse wird ein deutlicher Hydrophob-Effekt, bei Kontaktwinkeln zwischen 50° und 95° gezeigt – immer in Abhängigkeit der Gesamtformulierung und des Brennbereiches. Durch Zugabe von Nitriden oder Boriden, wie in Beispiel 1 beschrieben, kann der Kontaktwinkel auf 80° bis 100° erweitert werden.Of the Use of fluorine- or fluoride-containing frits in standard glazes does not produce any hydrophobic effects. As a rule, the contact angles are there between 3 ° and 10 °. By replacing oxidic Raw materials against fluorine- or fluoride-containing materials in the coating composition becomes a significant hydrophobic effect, at contact angles between 50 ° and 95 ° - always in dependence the overall formulation and the firing range. By adding Nitrides or borides, as described in Example 1, the contact angle be extended to 80 ° to 100 °.
Beim Wechsel vom oxidierenden Brand zum Reduktionsbrand oder auch nur zum Brand in Intertgasatmospäre, zeigt sich bei der erfindungsgemäßen Zusammensetzung sogar er Superhydrophobeffekt, beginnend mir Kontaktwinkeln größer 130°.At the Change from oxidizing fire to reduction firing or even just to the fire in Intertgasatmospäre, shows up in the inventive Composition even he super hydrophobic effect, starting with contact angles greater than 130 °.
Die erfindungsgemäße Zusammensetzung kann durch eine Vielzahl weiterer Rohstoffe in seinen Eigenschaften gesteuert werden. Neben Additiven und Füllstoffen können spezielle „Härter”, oder Koppler in der Zusammensetzung enthalten sein, die aus der erfindungsgemäßen Zusammensetzung ein sehr vielfältig einsetzbares Material machen, welches auf Keramik, Glas und metallischen Substraten aufgebracht und verdichtet werden kann.The Composition according to the invention can be replaced by a Variety of other raw materials are controlled in its properties. In addition to additives and fillers, special "hardeners", or couplers contained in the composition resulting from the Composition of the invention a very diverse make usable material, which on ceramic, glass and metallic Substrates can be applied and compacted.
Neben dem Schutz des Substrates stellt sich eine Niedrig-Energie-Oberfläche ein, welche zumindest als hydrophob, wenn nicht sogar superhydrophob bezeichnet werden kann. Durch diese Niedrig-Energie-Oberfläche wird das Anhaften von Verschmutzungen deutlich reduziert, s. d. die Oberfläche leichter abzureinigen ist.Next The protection of the substrate presents a low-energy surface which is at least hydrophobic if not superhydrophobic can be designated. Through this low-energy surface the adhesion of dirt is significantly reduced, s. d. the surface is easier to clean off.

Beispiele 1:Examples 1:
Folgende
Versätze in Mol% werden in einer Rührwerkskugelmühle
in Dowanol DPM auf eine Feinheit von einem d50 Wert
von etwa 1,5 μm klein gemahlen. Der Feststoffgehalt von
Nr. 1. betrug 38% (Mischung A) und von Nr. 2 36,5% (Mischung B).
Anschließend wird eine 45%ige Paste aus gemahlen Petalit (Mischung C) und Kalifeldspat in Dowanol (Mischung D) mit einem d50 Wert von 1,8 μm bzw. 1,3 μm bereitet.Subsequently, a 45% paste of ground petalite (mixture C) and potassium feldspar in Dowanol (mixture D) with a d 50 value of 1.8 microns and 1.3 microns is prepared.
So ergeben sich weiße glasige Überzüge für Steinzeug (Brennbreich: 1.200°C–1.260°C) aus einer Kombination von 10–30% Mischung D und 70–90% aus Mischung A.So arise white glassy coatings for Stoneware (Brennbreich: 1,200 ° C-1,260 ° C) from a combination of 10-30% mixture D and 70-90% from mixture A.
Aus Kombinationen von 5–40% Mischung C und 60–95% aus Mischung B entstehen leicht opake glasige Überzüge für Steingutfliesen (Brennbereich: 1.080°C–1150°C).Out Combinations of 5-40% blend C and 60-95% Mix B produces slightly opaque glassy coatings for stoneware tiles (burning range: 1,080 ° C-1150 ° C).
Beispiel 2:Example 2:
Die
Nitride können auch gegen korrespondierende Oxide ersetzt
werden, wenn die Überzugsmasse chemisch weniger aggressiven
Medien ausgesetzt wird.
Es ergeben sich auch weiße glasige Überzüge für Steinzeug 1.200°C–1.260°C aus der Mischung Nr. 3 bei einem Feststoffgehalt von 40% in Dowanol DPM.It also arise white glassy coatings for stoneware 1.200 ° C-1.260 ° C from mixture no. 3 at a solids content of 40% in Dowanol DPM.
