Description

Es wurde gefunden, daß Rhodanverbindungen bekannte Anstrichmassen, die aus anorganischen Pigmenten, Phosphorsäure und Wasser, gegebenenfalls auch Füllstoffen zusammengesetzt sind, verbessern. Bringt man die bekannten Anstrichmittel als solche auf Metallflächen auf, so bilden sich häufig infolge Wasserstoffentwicklung feine Gasbläschen, die den aufgestrichenen Film währendIt has been found that rhodan compounds known paint compositions, which consist of inorganic Pigments, phosphoric acid and water, optionally also fillers are, improve. If the known paints are applied as such On metal surfaces, fine gas bubbles often form as a result of the evolution of hydrogen, which the coated film during

to des Erhärtungsvorganges durchbrechen und so zur Ausbildung von Löchern und Blasen Anlaß geben. Die Überzugsfilme haften auch nicht immer fest auf der Metallunterlage. Diese Nachteile werden durch den Zusatz von Rhodanverbindungen gemäß der Erfindung beseitigt.to break through the hardening process and so to the formation of holes and bubbles To give reason. The coating films also do not always adhere firmly to the metal substrate. These disadvantages are eliminated by adding rhodane compounds according to the invention.

An erster Stelle kommen organische Rhodanverbindungen, wie Methyl-, Butyl-, Amyl-, Phenyl-, Benzyl-, NitrobenzylrhodanM und Rhodanaceton, in Betracht. Es sind aber auch anorganische Rhodanverbindungen, insbesondere Natrium-, Kalium-, Ammonium-, Lithium-, Magnesium-, Calcium-, Barium-, Zink-, Mangan-, Nickel-, Kobalt-, Eisen-, Chrom-, Blei-, Kupfer- und Kalium-Chrom-Rhodanid, geeignet. In den meisten Fällen genügt ein Zusatz von 1 o/o der Rhodanverbindung, bezogen auf die Anstrichmasse, und vielfach eine noch geringere Menge, um die Schutzwirkung hervorzurufen. Bei Verwendung solcher Rhodanverbindungen, die in der Anstrichmasse unlöslich sind, werden zweckmäßig Lösungs- oder Emulgierungsmittel zugesetzt, so daß die Rhodanverbindung in feinster Verteilung vorliegt.In the first place, organic rhodan compounds such as methyl, butyl, amyl, phenyl, benzyl, nitrobenzyl rhodanM and rhodanacetone come into consideration. But there are also inorganic rhodan compounds, in particular sodium, potassium, ammonium, lithium, magnesium, calcium, barium, zinc, manganese, nickel, cobalt, iron, chromium, lead, Copper and potassium-chromium-rhodanide, suitable. In most cases, it is sufficient to add 1 o / o of the rhodan compound, based on the paint, and in many cases an even smaller amount to produce the protective effect. When using rhodan compounds which are insoluble in the paint, solvents or emulsifiers are expediently added so that the rhodan compound is finely divided.

Die Verwendung geringer Mengen des Erzeugnisses aus der Umsetzung von Rhodanwasserstoffsäure mit einer Pyridinbase in Metallbeizen, auch solchen auf Grundlage von Phosphorsäure, ist bekannt.The use of small quantities of the product from the conversion of hydrofluoric acid with a pyridine base in metal pickles, including those based on phosphoric acid, is known.

Indessen lieü sich nicht ohne weiteres voraussehen, wie sich der Zusatz von Rhodanverbindungen zu einem anorganische Pigmente und wässerige Phosphorsäure, gegebenenfalls auch Füllstoffe enthaltenden Anstrichmittel auswirken würde.However, it was not easy to foresee how the addition of rhodan compounds to an inorganic pigment and aqueous phosphoric acid, optionally paints containing fillers would also have an effect.

B eispielιExample

Aus 25 Teilen (Gewichtsteilen) Chromoxydgrün, 10 Teilen Kaolin, 24,38 Teilen wässeriger Phosphorsäure (spez. Gew. 1,219) un<i 0,7 Teilen Zinkrhodanid wird durch Vermählen eine Anstrichfarbe hergestellt. Die Masse läßt sich ohne Schwierigkeit zu einem gleichmäßigen Anstrich auf metallischen Oberflächen verarbeiten.A paint is produced by grinding from 25 parts (parts by weight) of chromium oxide green, 10 parts of kaolin, 24.38 parts of aqueous phosphoric acid (specific weight 1.219) and < i 0.7 parts of zinc rhodanide. The mass can be processed into an even coat of paint on metallic surfaces without difficulty.

Durch Vermählen von 30 Teilen Eisenoxydrot, 5 Teilen Tonerde, 31,4 Teilen wässeriger Phosphorsäure (spez. Gew. 1,254), 3,94 Teilen Alkohol und 0,5 Teilen Phenylrhodanid wird eine Anstrichfarbe erhalten, die sich als Schutzmittel für metallische Oberflächen sehr gut eignet.By grinding 30 parts of red iron oxide, 5 parts of clay, 31.4 parts of aqueous Phosphoric acid (specific weight 1.254), 3.94 parts of alcohol and 0.5 part of phenylrhodanide Get a paint that is very useful as a protective agent for metallic surfaces well suited.
