Abstract

Water- and dirt-repellent coating for glass, metals, plastics and other materials is produced by flame coating using silicon tetrafluoride and/or titanium tetrachloride in a natural gas/oxygen, methane/oxygen or other hydrocarbon/oxidant flame and has an extremely rough microscopic surface structure. It is suitable for almost all heat-resistant materials and makes window cleaning unnecessary. Water- and dirt-repellent coating for glass, metals, plastics and other materials is produced by flame coating using silicon tetrafluoride (SiF4) and/or titanium tetrachloride (TiCl4) in a natural gas/oxygen, methane/oxygen or other hydrocarbon/oxidant flame and has an extremely rough microscopic surface structure. It is suitable for almost all heat-resistant materials; cannot be wetted by liquid; causes photocatalytic decomposition if particles of dirt stick to the surface; forms a firm bond with various silicate glasses, so that it very durable; and makes window cleaning unnecessary.

Description

Es ist allgemein bekannt, daß es umweltschädigend, teuer und oft umständlich ist Fensterscheiben, Fassaden, Autos und sonstige Dinge ständig reinigen zu müssen.It is well known that it is harmful to the environment, expensive and often cumbersome Always having to clean window panes, facades, cars and other things.

Der im Patentanspruch 1 aufgeführten Erfindung liegt das Problem zugrunde, die fortwährende Verschmutzung von Fensterscheiben, Fassaden, Autos und anderen Dingen zu unterbinden und das ständige Reinigen solcher Dinge zu unterbinden.The invention listed in claim 1 is based on the problem, the ongoing To prevent and prevent pollution of window panes, facades, cars and other things to prevent the constant cleaning of such things.

Dieses Problem wird durch die im Patentanspruch 1 aufgeführten Merkmale gelöst.This problem is solved by the features listed in claim 1.

Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, das mit der Beschichtung versehene Dinge nicht mehr so oft gereinigt zu werden brauchen, das viele Flüssigkeiten wie Wasser, Zuckerlösung, Honig, Papierkleber auf Wasserbasis usw. die beschichtete Oberfläche nicht mehr benetzen können sondern einfach an ihr abrutschen. Ein weiterer Vorteil der Erfindung ist es, dass sofern es sich um eine solche Beschichtung handelt, welche mit einer TiCl4-SiF4-Methan-Gemisch/Sauerstoff-Flamme hergestellt wurde, eventuell anhaftende Ruß und Schadstoffpartikel unter Einfluß der Sonne und Luftfeuchtigkeit durch das so in der Beschichtung enthaltene TiO2 photokatalytisch zersetzt werden.The advantages achieved with the invention are in particular that things with the coating no longer need to be cleaned as often, that many liquids such as water, sugar solution, honey, water-based paper glue etc. the can no longer wet coated surface but simply slide off it. On Another advantage of the invention is that if such a coating is involved, which was produced with a TiCl4-SiF4-methane mixture / oxygen flame, possibly adhering soot and pollutant particles under the influence of the sun and humidity through the TiO2 contained in the coating can be decomposed photocatalytically.

Eine vorteilhafte Ausgestaltung der Erfindung ist in Patentanspruch 2 angegeben. Eine Weiterbildung nach Patentanspruch 2 ermöglicht es, die Beschichtung auf das Trägermaterial abzustimmen und so eine verbesserte Haftung zu erreichen.An advantageous embodiment of the invention is specified in claim 2. A Further development according to claim 2 enables the coating on the carrier material to coordinate and thus achieve improved liability.

Ein Ausführungsbeispiel ist im folgenden dargestellt:
Einem Gebläsebrenner wird Erdgas(Methan) mit einem Anteil von ca. 10% SiF4 (Siliciumtetraluorid) und als Oxidationsmittel Sauerstoff zugeführt, so dass er mit kräftiger Flamme brennt. Nun wird die Flamme auf eine Ceran- oder Glasplatte gerichtet und so auf ihr hin und her geschwenkt dass eine gleichmäßige dünne Beschichtung entsteht. Die so erhaltene beschichtete Platte wird langsam abgekühlt und zeigt fortan auf der beschichteten Fläche das für die Beschichtung typische wasserabweisende Verhalten.An exemplary embodiment is shown below:
Natural gas (methane) with a share of approx. 10% SiF4 (silicon tetraluoride) and oxygen as an oxidizing agent are fed into a forced draft burner so that it burns with a strong flame. Now the flame is directed onto a ceramic or glass plate and swung back and forth on it so that an even, thin coating is created. The coated plate thus obtained is slowly cooled and from then on shows the water-repellent behavior typical of the coating on the coated surface.

Werden dem Erdgas neben SiF4 auch noch 2-5% TiCl4-Dampf zugesetzt, zeigt die Beschichtung auch schon beschriebene photokatalytische Verhalten.If 2-5% TiCl4 vapor is also added to the natural gas in addition to SiF4, the coating also shows the photocatalytic behavior already described.
