Verfahren zum Schütze und zum Verzieren von Aluminium.Method of protecting and decorating aluminum.
Vorliegende Erfindung betrifft ein Verfahren, durch welches Aluminium mit einem vollkommen haftenden Überzug von Substanzen, die für äußere Agenzien unangreifbar bleiben, bedeckt wird, wobei diesem Überzug eine ausgesprochene durchscheinende Beschaffenheit erteilt werden kann.The present invention relates to a method by which aluminum with a perfectly adhesive coating of substances that remain invulnerable to external agents, covered this coating is given a distinctly translucent quality can be.
Das nach vorliegendem Verfahren behandelte Metall läßt sich mechanisch bearbeiten, ohneThe metal treated according to the present process can be worked mechanically without
ίο daß der auf dem Metall aufgetragene Überzug durch diese Bearbeitung gefährdet wird.ίο that the coating applied to the metal is endangered by this processing.
Das Verfahren vorliegender Erfindung benötigt keine Vorbehandlung des Metalls zum Zwecke der Reinigung seiner Oberfläche. Die zu behandelnden Gegenstände werden zunächst der Wirkung eines Strahles eines wäßrigen Gemenges von Stoffen ausgesetzt, die bestehen aus einem alkalischen Dekapierungsmittel, vorzugsweise dem im Handel als Marseiller Dekapierungsmittel bekannten ammoniakalischen Nickelsulfat und präzipitierter Kieselsäure. Diese Mischung wird durch einen der bekannten Spritzapparate unter Verwendung von Luft undunter Beimengung einer gewissen Menge von Wasserstoff auf das Aluminium aufgespritzt, wobei es vorteilhaft ist, daß der Wasserstoff durch Einwirkung von Salzsäure auf Metalle, vorzugsweise Zink und Zinn, entsteht, weil die Chlorverbindungen dieser Metalle die erstrebte Wirkung günstig beeinflussen.The method of the present invention does not require any pre-treatment of the metal for Purpose of cleaning its surface. The items to be treated are first exposed to the action of a jet of an aqueous mixture of substances that exist from an alkaline pickling agent, preferably that commercially available as Marseille pickling agent known ammoniacal nickel sulfate and precipitated silica. This mixture is made by one of the well-known Spray guns using air and adding a certain amount of Hydrogen sprayed onto the aluminum, it being advantageous that the hydrogen by the action of hydrochloric acid on metals, preferably zinc and tin, arises because the Chlorine compounds of these metals have a beneficial effect on the desired effect.
Durch die kräftige mechanische Wirkung und die gleichzeitig stattfindende chemische Reaktion der Bespritzung wird erreicht, daß das Metall immer im blanken Zustande, ohne daß sich also hinderliche Niederschläge bilden können, mit den zur chemischen Einwirkung bestimmten Körpern in innige Berührung kommt. Diese Behandlung wird so lange fortgesetzt, bis die ganze Oberfläche des -Metalls mit einem Überzug von mattem Aussehen bedeckt ist.Due to the powerful mechanical effect and the chemical reaction that takes place at the same time the spraying is achieved that the metal is always in the bright state, without So obstructive precipitates can form, with those intended for chemical action Body comes into intimate contact. This treatment is continued until the whole surface of the metal is covered with a coating of matt appearance.
Die Gegenstände werden hierauf im Wasser gewaschen und hernach bei hoher Temperatur getrocknet, so daß durch diese heiße Trocknung dem Überzug die gewünschte Haftbarkeit erteilt wird. .The objects are then washed in water and then at high temperature dried, so that this hot drying gives the coating the desired adhesion is granted. .
Das so vorbehandelte Aluminium wird nun mit einer Mischung von Lösungen von Guttapercha, Kautschuk und nitriertem Rizinusöl oder deren Surrogate behandelt und hierauf wiederum bei hoher Temperatur getrocknet, wobei der Gummi, wenn nötig, mit irgendeinem der bekannten Mittel vulkanisiert werden kann.The pretreated aluminum is now treated with a mixture of solutions of gutta-percha, Treated rubber and nitrated castor oil or their surrogates and then dried again at high temperature, the rubber being vulcanized, if necessary, by any of the known means can.
Das Verfahren wird nun durch die Weiterbehandlung des Aluminiums mit einer Auflösung von nitrierter Cellulose oder schwer entflammbaren Celluloiden, wie die im Handel als Cellit, Cygoid bezeichneten, und Fettsäuren, wie Essigsäure, Milchsäure usf., bei Gegenwart von kleinen Mengen von anorganischen oder organischen Salzen, vorzugsweise Chloriden, fortgesetzt. Die Cellulosen können eventuell ersetzt werden durch Casein, Fibrin oder durch Kondensationsprodukte von Phenol, Formaldehyd und organischen Säuren in den dazu geeigneten Lösungsmitteln.The process is now carried out by further treating the aluminum with a dissolution of nitrated cellulose or flame-retardant celluloids, such as those commercially available referred to as cellite, cygoid, and fatty acids such as acetic acid, lactic acid, etc., in the presence of small amounts of inorganic or organic salts, preferably chlorides, continued. The celluloses can possibly be replaced by casein, fibrin or by Condensation products of phenol, formaldehyde and organic acids in the addition suitable solvents.
Das bis hierher behandelte Metall wird nunmehr in heißer Luft getrocknet und der Überzug,The metal treated so far is now dried in hot air and the coating,
wenn nötig, mit Formaldehyd oder anderen Härtemitteln gehärtet.if necessary, hardened with formaldehyde or other hardening agents.
Es wird durch diese Behandlung auf dem Metall ein elastischer, glatter, vollständig haftender durchscheinender Überzug erzeugt, der sich vom Metall auch durch mechanische Bearbeitung nicht loslöst. Die Stärke dieses Überzuges kann je nach dem Verwendungszweck variieren; der Vorgang wird einfach soThis treatment makes the metal more elastic, smooth and completely adhesive A translucent coating is created, which can also be removed from the metal by mechanical processing does not detach. The thickness of this coating can vary depending on the intended use; the process just becomes that way
ίο lange wiederholt, bis der Überzug die gewünschte Stärke erlangt hat.ίο repeatedly until the coating is the desired Has gained strength.
Der Überzug hat im weiteren den Vorzug, eine ausgesprochene durchscheinende Beschaffenheit zu besitzen, derart, daß derselbe gestattet, auf dem Aluminium vor seiner Behandlung angebrachte Dekorationen wohl zu bedecken, dieselben jedoch deutlich sichtbar durchscheinen zu lassen. Infolge dieser letzt erwähnten Eigenschaft des Überzuges ist es möglich, das Aluminium nach Wunsch zu verzieren und diese Verzierungen auf dem Aluminium zu erhalten.In addition, the coating has the advantage of being extremely translucent in such a way that it allows it to be applied to the aluminum prior to its treatment to cover attached decorations, but to let them shine through clearly. As a result of this last mentioned property of the coating it is possible to decorate the aluminum as desired and to get these decorations on the aluminum.
