Description

Verfahren zur Behandlung von Bronzelacküberzügen. Für gewisse Zwecke, bei denen Brozelacke, das sind Lacke, .die ein fein verteiltes Metall enthalten, o. dgl. verstrichen werden, ist es von Wichtigkeit, die eigentliche Lackschicht oberflächlich zu entfernen, um entweder hierdurch physikalische Eigenschaften des Metalles wirksamer zu machen oder aber, um dem Ganzen ein gefälligeres Aussehen zu geben. So besitzt ein Bronzelackauftrag immer die Metalle in der Lackschicht eingebettet, wodurch z. B. die Leitfähigkeit der Metalle aufgehoben wird und der Bronzeaufstrich selbst, wie der Fachmann sagt, ein »duffes« Aussehen hat.Process for the treatment of bronze lacquer coatings. For certain purposes where Brozelacke, that is lacquer, .that contain a finely divided metal, o. The like. Be passed, it is important that the actual paint layer to remove superficially in order to either result in physical properties of the To make metal more effective or to give the whole thing a more pleasing appearance admit. A bronze paint application always has the metals in the paint layer embedded, whereby z. B. the conductivity of the metals is canceled and the Bronze coating itself, as the expert says, has a "duffy" appearance.

Es wurde nun gefunden, daß diese Übelstände zu beseitigen sind, indem man von dem Bronzelackauftrag die Lackschicht oberflächlich, z. B. durch Verseifen:, entfernt. Hierdurch erzielt man sowohl elektrische Leitfähigkeit des Anstriches, als auch ein gefälligeres Aussehen.It has now been found that these deficiencies can be eliminated by one of the bronze paint application, the paint layer superficially, z. B. by saponification :, removed. This achieves both electrical conductivity of the paint, as well as a more pleasing appearance.

Die zur Verwendung kommenden Lacke richten sich nach der Art des zu überziehenden Gegenstandes. Es werden sowohl Öl-, wie Spiritus-, wie Zelluloseesterlacke verwendet. In ihnen: ist die leitende Substanz, wie z. B. Kupfer, Graphit o. dgl. in feiner Verteilung suspendiert. Nach dem Trocknen dieser Lacke sind die Überzüge z. B. elektrisch nichtleitend, da die einzelnen Panikelchen elektrisch. leitender Substanzen durch die isolierende Lackschicht getrennt werden. Um diese Trennungsschicht zu beseitigen, soll die isolierende Lackschicht entfernt werden. Dies kann geschehen, indem man sie z. B. verseift, wodurch die einzelnen Partikelchen miteinander in Berührung kommen, zum mindesten jedoch durch die hygroskopischen Eigenschaften der verseiften Lackschicht leitend gemacht werden.The varnishes used depend on the type of to coating object. Both oil and spirit as well as cellulose ester varnishes are used used. In them: is the conductive substance, such as B. copper, graphite or the like. suspended in fine distribution. After these varnishes have dried, the coatings are z. B. electrically non-conductive, since the individual particles are electrical. senior Substances are separated by the insulating lacquer layer. Around this separation layer To remove, the insulating lacquer layer should be removed. This can be done by z. B. saponified, whereby the individual particles with each other in Come into contact, at least because of the hygroscopic properties of the saponified lacquer layer can be made conductive.

Als Verseifungsmittel können in bekannter Weise Schwefelsäure, Salzsäure o. dgl., oder aber auch Laugen, wie Natronlauge, Kalilauge oder.ähnliche, benutzt «-erden, die sowohl Öllacke wie Zelluloseesterlacke verseifen.Sulfuric acid and hydrochloric acid can be used as saponifying agents in a known manner or the like, or alkalis, such as caustic soda, potassium hydroxide or similar, are used «Earths, which saponify both oil varnishes and cellulose ester varnishes.

So verfährt man z. B. zweckmäßig derart, daß man einen getrockneten Bronzelackaufstrich mit verdünnten Säuren oder Laugen betupft und, um die weitere Einwirkung der Säuren bzw. Alkalien zu verhindern, auswäscht und somit die Metalle blanklegt, wodurch der Aufstrich z. B. elektrische Leitfähigkeit erhält und das metallische.Aussehen des verwendeten Metalles wieder zur Geltung kommt.This is how you proceed z. B. expedient in such a way that you have a dried Bronze paint spread with diluted acids or alkalis and dabbed to the further To prevent the effects of acids or alkalis, and thus washes out the metals blank, whereby the spread z. B. receives electrical conductivity and that metallic. Appearance of the metal used comes into its own again.

Letzteres ist z. B. von großem Interesse bei der Herstellung von Metallpapieren.The latter is z. B. of great interest in the manufacture of metal papers.
