Description
Ein- oder beiderseitig mit transparenter Schutzschicht überzogenes Sichtglas und Verfahren zu seiner . Herstellung Die Erfindung bezieht sich auf ein- oder beiderseitig mit transparenten Schutzschichten überzogene Sichtgläser.Covered on one or both sides with a transparent protective layer Sight glass and procedure for its. Manufacture The invention relates to a or sight glasses coated on both sides with transparent protective layers.
Bei einer großen Zahl technischer Arbeiten, deren Durchführung oder Überwachung gewisse Sicherheitsmaßnahmen für das Bedienungspersonal erfordert, werden Sichtgläser gebraucht, welche entweder als Fenster in Steuerkabinen u. dgl. oder lediglich als Augenschutz in Form -von Gesichtsschützern oder Brillen zur Verwendung kommen. Solche Gläser sind vor allem -in metallverarbeitenden Betrieben einem stärken Verschleiß unterworfen, da glühende Metallspritzer; die in Gießereien oder beim Schweißen- oder Schleifen meist. unvermeidlich sind, sich an der Glasoberfläche festsetzen bzw. einbrennen und dadurch das Glas oft schon nach wenigen Stunden als Sichtglas unbrauchbar machen. Da Kunststoffe und organische Gläser in dieser Hinsicht weniger empfindlich sind, zieht man sie vielfach für solche Zwecke dem Silikatglas vor. Dabei muß man allerdings den großen Nachteil in Kauf nehmen, daß solche Stoffe keinerlei optische Qualität besitzen, sondern mehr oder minder unebene, leicht verkratzbäre Oberflächen aufweisen, welche eine erhebliche Behinderung für exaktes Arbeiten hervorrufen.In the case of a large number of technical work, the implementation or monitoring of which requires certain safety measures for the operating personnel, sight glasses are used which are used either as windows in control cabins and the like, or merely as eye protection in the form of face guards or glasses. Such glasses are above all - subject to heavy wear and tear in metalworking plants because of glowing metal splashes; mostly in foundries or when welding or grinding. are inevitable, stick to the surface of the glass or burn in, often rendering the glass unusable as a sight glass after just a few hours. Since plastics and organic glasses are less sensitive in this regard, they are often preferred to silicate glass for such purposes. However, one has to accept the great disadvantage that such materials have no optical quality, but have more or less uneven, easily scratchable surfaces, which cause a considerable hindrance to precise work.
Zur Vermeidung dieses Nachteils wurden schon mehrfach Vorschläge gemacht, welche zum Ziele hatten, Sichtscheiben aus normalem Silikatglas zu verwenden, das durch einen spritzen abweisenden Überzug gegen das Einbrennen der glühenden Teilchen geschützt ist. Wegen des in dieser Hinsicht günstigeren Verhaltens von Kunststoffen, Kunstharzen und organischen Lacken war es nahehegend, Überzüge aus solchen Stoffen auf den zu schützenden Gläsern niederzuschlagen. Die mangelhafte optische Qualität und geringe Ahriebfestigkeit dieser Überzüge verhinderte jedoch in den meisten Fällen ihre praktische Anwendung. Nach einem weiteren Vorschlag wurde sodann empfohlen, wasserhaltige Kieselsäure- bzw. Alkalisilikatschichten unter Ausnutzung des Leydenfrostschen Phänomens zu demselben Zweck zu verwenden, wobei der beim Auftreffen eines glühenden Teilchens entwickelte Wasserdampf ein Schutzpolster auf dem Glase bildete. Offenbar kann diese Wirkung aber nur nur so lange bestehen, als genügend Wasser in der Schutzschicht enthalten ist; außerdem ist mit zunehmender Entwässerung von Silikatschichten die Gefahr der Trübung und der Rißbildung gegeben.To avoid this disadvantage, several suggestions have been made which had the goal of using viewing panels made of normal silicate glass, the by a spray-repellent coating against the burning in of the glowing particles is protected. Because of the more favorable behavior of plastics in this regard, Synthetic resins and organic paints were natural, coatings made from such substances to be knocked down on the glasses to be protected. The poor optical quality and poor abrasion resistance of these coatings prevented in most cases their practical application. After a further suggestion, it was then recommended that water-containing silica or alkali silicate layers using Leydenfrostschen Phenomenon to be used for the same purpose, the one being hit by a glowing one Particles, water vapor developed a protective cushion on the glass. Apparently However, this effect can only last as long as there is enough water in the protective layer is included; in addition, with increasing dewatering of silicate layers is the There is a risk of cloudiness and cracking.
Bei Versuchen, das Problem in befriedigender Weise zu lösen, wurde nun überraschend gefunden, daß man Sichtgläser mit optisch einwandfreien und äußerst beständigen, abriebfesten Schutzschichten erhält, wenn diese aus einem lösungsmittelfreien, bis mindestens 250° C temperaturbeständigen Überzug von anorganischen oxydischen Verbindungen und -einer metatl-bzw. metalloidorganischen Beimengung bestehen. Während lösungsmittelfreie Oxydschichteri für- sich allein keine oder nur eine sehr unbedeutende Schutz-Wirkung gegen Metallspritzer besitzen, zeigte sich, daß durch den Einbau der metallorganischen Komponente ein hochelastisches Gefüge geschaffen werden kann, bei dem offenbar infolge einer sehr weitgehengen gegenseitigen Absättigung aller Valenzkräfte ein Anhaften auftreffender Metallteilchen nicht mehr möglich ist. Daß es sich dabei nicht um bloße additive Mischungen zweier oder mehrerer Stoffe handelt, geht auch daraus hervor, daß die Temperaturbeständigkeit der erfindungsgemäßen Schutzüberzüge um 1.00 bis 200° C höher liegen kann als die der eingebauten organischen Komponente für sich allein. Die Schichten lassen sich ferner im Gegensatz zu ihrem organischen Anteil als optisch homogene, klare Filme von einer Dicke bis zu 10[, und mehr niedergeschlagen und weisen ein vorzügliches Haftvermögen an der Glasoberfläche auf.When trying to solve the problem in a satisfactory manner, has been now surprisingly found that you can see glasses with optically flawless and extremely durable, abrasion-resistant protective layers, if these are made of a solvent-free, Coating of inorganic oxydic coatings that is temperature-resistant up to at least 250 ° C Connections and a metatl or. metalloid organic admixture exist. While solvent-free oxide layers on their own, none or only a very insignificant one Have a protective effect against metal splashes, it was found that through the installation a highly elastic structure can be created for the organometallic component, apparently as a result of a very extensive mutual saturation of all Valence forces, it is no longer possible for metal particles to adhere. That it is not a mere additive mixture of two or more substances, it also emerges from this that the temperature resistance of the protective coatings according to the invention can be 1.00 to 200 ° C higher than that of the built-in organic component for yourself. The layers can be further unlike their organic Share as optically homogeneous, clear films with a thickness of up to 10 [, and more precipitated and have excellent adhesion to the glass surface.
Als geeignete anorganische Verbindungen kommen insbesondere die in bekannter Weise durch hydrolytische Umsetzung und Erhitzung aus Estern von Säuren, beispielsweise Halogensäuren, der Metalle der IV. Gruppe des Periodischen Systems erhaltenen Oxyde in Betracht; im Hinblick auf große Härte und Haftfestigkeit mit der Glasoberfläche bewähren sich besonders Mischungen von Si 02 und Ti 02 oder Zr 02, die außerdem den Vorteil. bieten, daß ihre Lichtbrechung durch das Mischungsverhältnis der des Glases optimal angepaßt werden kann.Suitable inorganic compounds are, in particular, those in known way by hydrolytic conversion and heating from esters of acids, for example halogen acids, the metals of group IV of the Periodic Table oxides obtained into consideration; in terms of great hardness and adhesive strength Mixtures of Si 02 and Ti 02 or Zr 02, which also has the advantage. offer that their light refraction due to the mixing ratio which can be optimally adapted to the glass.
_. Für die _meiall,. bzw.- metalloidorganische Beimengung'eignen sich z. B: Verbindungen vom Typ R" (MeORR7x - MeRR'R" bzw. ' :-,R @@ (MeO R)x -, Me-R.RI'i, Die Strukturformeln dieser";Ver;bindungen sind fol- o gende , a':.: .. . Hierbei bedeutet x den Polymerisatiönsgrad für die Gruppe in ( ). R,R' und R" können beliebige, auch gleiche, organische Radikale sein, wobei mindestens R ein an Me direkt gebundenes C-Atom aufweist und R' und R" vorteilhaft, teilweise durch ein Halogen ersetzt sein kann. Für 3wertiges Me entfällt R'._. For the _meiall ,. or metalloid-organic admixtures are suitable e.g. B: Compounds of type R "(MeORR7x - MeRR'R" or ': -, R @@ (MeO R) x -, Me-R.RI'i, The structural formulas of these "; compounds are fol- o gende, a ':.: ... Here, x denotes the degree of polymerisation for the group in (). R, R 'and R "can be any organic radicals, including those which are identical, where at least R has a carbon atom directly bonded to Me and R' and R" can advantageously be partially replaced by a halogen. R 'is omitted for 3-valued Me.
Besonders günstig sind die entsprechenden Verbindungen des Al, Si, Sn oder Ti. Der prozentuale Anteil der metallorganischen Beimengung soll zweckmäßig zwischen 5 und 50%, vorzugsweise zwischen 5 und 15%, bezogen auf die Gesamtmasse der fertig aufgebrachten Schicht, betragen.The corresponding compounds of Al, Si, Sn or Ti. The percentage of the organometallic admixture should be appropriate between 5 and 50%, preferably between 5 and 15%, based on the total mass of the completely applied layer.
Das Aufbringen der Schutzschicht auf den Sichtgläsern erfolgt zweckmäßig durch Tauchen der Gläser in Lösungen der genannten Stoffe oder durch Absenken, Aufschleudern oder Aufsprühen derselben. Als Lösungsmittel können verschiedene organische Lö= sungsmittel, vorzugsweise Alkohole oder Ester, verwendet werden, sofern die Ausgangsstoffe der beiden zum Schichtenaufbau dienenden Stoffgruppen in ihnen gleichzeitig löslich sind. Nach dem Aufbringen wird der Flüssigkeitsfilm zunächst unter mäßigem Erwärmen getrocknet, wobei gegebenenfalls an der feuchten Luft die erwähnte hydrolytische Umsetzung der in Oxyde umzuwandelnden Ester erfolgen kann, und hierauf das beschichtete Glas bis zum Austreiben des Lösungsmittels und der etwa flüchtigen Reaktionsprodukte, d. h. mindestens auf 250° C, erhitzt.The protective layer is expediently applied to the sight glasses by immersing the glasses in solutions of the substances mentioned or by lowering them or by spinning them on or spraying them on. Various organic solvents can be used as solvents solvents, preferably alcohols or esters, can be used, provided the starting materials of the two groups of substances used to build up layers are simultaneously soluble in them are. After application, the liquid film is first heated gently dried, where appropriate in the moist air the mentioned hydrolytic Implementation of the ester to be converted into oxides can take place, and then the coated Glass until the solvent and any volatile reaction products are driven off, d. H. heated to at least 250 ° C.
