Description

DEUTSCHESGERMAN

Es ist bereits bekannt, einen reflexionsvermindernden Überzug auf optisch wirksamen Flächen, insbesondere auf Glas, und auch Schichten zum Schutz empfindlicher Gläser dadurch zu erzeugen, daß man den Gegenstand nach erfolgter Reinigung in ein Hochvakuum einführt, seine Oberfläche mit dem Dampf eines Überzugsmetalls, z. B. reinsten Siliciums oder siliciumähnlicher Elemente, beschichtet und anschließend daran die so hergestellten Schichten oxydiert. It is already known to use an anti-reflective Coating on optically effective surfaces, in particular on glass, and also layers for protection To produce more sensitive glasses by the fact that the object after cleaning in a Introduces high vacuum, its surface with the vapor of a coating metal, e.g. B. purest silicon or silicon-like elements, coated and then oxidized the layers produced in this way.

Es ist weiterhin bekannt, daß wasserabstoßende Überzüge auf Glas, Porzellan u. dgl., durch Überziehen der Oberfläche des Gegenstandes mit einer Lösung eines hydrolysierbaren Silans oder eines polymerisierten oder hydrolysierten Produkts desselben erzeugt werden können, worauf der Gegenstand auf eine Temperatur erhitzt wird, die unterhalb des Zersetzungspunktes des Silans liegt.It is also known that water-repellent coatings can be applied to glass, porcelain and the like by coating the surface of the article with a solution of a hydrolyzable silane or a polymerized one or hydrolyzed product thereof can be generated, whereupon the article is based a temperature is heated which is below the decomposition point of the silane.

Gemäß der vorliegenden Erfindung werden der glasartigen Oberfläche eines isolierenden Materials wasserabstoßende Eigenschaften erteilt, indem man den Gegenstand mit der Lösung eines organischen Silikats überzieht, worauf der Gegenstand unter Entfernung des Lösungsmittels auf eine die Zersetzung des Silikats herbeiführende Temperatur erhitzt wird, .so daß ein an der behandelten Fläche anhaftender, aus Kieselsäure bestehender Überzug von etwa molekularer Dicke verbleibt.According to the present invention, the vitreous surface of an insulating material Water-repellent properties are given by treating the object with a solution of an organic Silicate coats, whereupon the object undergoes decomposition with removal of the solvent of the silicate causing temperature is heated, .so that an adhering to the treated area, from Silica existing coating of approximately molecular thickness remains.

In diesem Sinne kann auf die wasserabstoßend auszubildende Fläche ein Überzug eines Tetraäthylorthosilikats gebracht werden, auf den man alsdann Hitze, κ. ß. mittels einer Flamme, derart einwirken läßt, daß das Tetraätbylorthosilikat zersetzt wird. Hierdurch ergibt sich ein weißer Kieselsäureniederschlag, von dem eine dünne Schicht an der Oberfläche haftet. Der Überschuß an Kieselsäure kann alsdann abgewischt werden. Der Überzug aus Tetraäthylorthosilikat kann z. B. in der Weise erzeugt werden, daß man den Gegenstand in das Äthylsilikat eintaucht oder die betreffende Fläche mit demselben besprüht, worauf man den Überschuß der Flüssigkeit von dem Gegenstand ablaufen läßt und ihn alsdann mit einer Flamme von genügender kinetischer Energie bzw. mit kurzer Flamme trockenbrennt.In this sense, a coating of a tetraethylorthosilicate can be applied to the surface to be made water-repellent to which one then heats, κ. ß. by means of a flame, can act in such a way that the tetraethyl orthosilicate is decomposed. This results in a white silica precipitate, of to which a thin layer adheres to the surface. The excess silica can then be wiped off will. The coating of tetraethyl orthosilicate can, for. B. be generated in such a way that the The object is immersed in the ethyl silicate or the surface in question is sprayed with the same, whereupon one let the excess of the liquid run off the object and then with a flame of sufficient kinetic energy or burns dry with a short flame.

Eine besondere Anwendungsform der Erfindung richtet sich auf die x\usbildung der Glashüllen von elektrischen Lampen, die Witterungseinflüssen unmittelbar ohne Schutzfassung ausgesetzt werden sollen, z. B. farbige dekorative Ausstellungslampen. In ähnlicher Weise kann man auch Glühlampen behandein, die in Innenräumen zur Verwendung kommen, in denen möglicherweise ein Bespritzen der Lampe mit Wassertropfen vorkommen kann.A particular form of application of the invention is directed to the formation of the glass envelopes of electrical lamps that are to be exposed to the weather without a protective socket, z. B. colored decorative exhibition lamps. Incandescent lamps can also be treated in a similar way, which are used indoors, where the lamp is likely to be splashed can occur with water droplets.
