Bei den Oelfarben nach Patentschrift Nr. 81187 macht sich der Uebelstand geltend, dafs die damit bestrichene Metallflä'che sich infolge des in der Farbe enthaltenen freien Wassers aümä'lig oxydirt. Um dem Fortschreiten dieser Oxydation Einhalt zu thun, werden nach vorliegendem Verfahren der Oelfarbe Schwefelverbindungen zugesetzt.In the case of the oil paints according to patent specification No. 81187, the disadvantage is that the Metal surfaces coated with it become blemished due to the free water contained in the paint oxidized. In order to put a stop to the progress of this oxidation, according to the present case Process of the oil paint sulfur compounds added.
Als solche Schwefelverbindungen eignen sich besonders die Sulfide der Alkalien (Schwefelleber) und der alkalischen Erden. Der Zusatz derselben geschieht am besten nach erfolgter Umsetzung zwischen den Aetzalkalien und den Schwermetallsalzen bezw. zwischen dem Bleioxyd, Alkalichlorid und den Schwermetallsalzen.The sulfides of alkalis (sulfur liver) are particularly suitable as such sulfur compounds. and alkaline earths. The addition of the same is best done after Implementation between the caustic alkalis and the heavy metal salts bezw. between the lead oxide, Alkali chloride and the heavy metal salts.
Die Wirkung des Zusatzes erklärt sich wahrscheinlich dadurch, dafs die entstandenen Schwermetallverbindungen sich z. B. mit Schwefelalkali zu Alkalihydrat und Schwermetallsulfid umsetzen, welch letzteres eine undurchdringliche Schutzschicht auf der Metalloberfläche bildet und dadurch die weitere Einwirkung des Wassers verhindert.The effect of the addition is probably explained by the fact that the resulting Heavy metal compounds z. B. with alkaline sulfur to alkali hydrate and heavy metal sulfide implement what the latter is an impenetrable protective layer on the metal surface forms and thus prevents the further action of the water.
Die Maximalmenge der zuzufügenden Schwefelverbindung läfst sich theoretisch bestimmen: sie darf höchstens der Menge der in der Farbe enthaltenen Schwermetallverbindungen äquivalent sein. Praktisch genügt z. B. ein Zusatz von ca. 5 bis 10 kg Schwefelleber auf 100 kg Bleiglätte und Schwermetallsalz. Nachdem sich die Glätte mit dem Kochsalz und der Schwermetallverbindung umgesetzt hat, wird die vorher in heifsem Wasser gelöste Schwefelleber zugefügt, die Mischung tüchtig durchgerührt, ausgewaschen und geprefst. Die erhaltene dicke graue Masse wird sodann mit ca. 90 kg Leinölfirnifs verrührt und durch die Oelfarbmühle gelassen.The maximum amount of the sulfur compound to be added can be determined theoretically: it may not exceed the amount of heavy metal compounds contained in the paint be. In practice, z. B. an addition of about 5 to 10 kg of sulfur liver per 100 kg Black lead and heavy metal salt. After the smoothness with the table salt and the heavy metal compound has implemented, the sulfur liver previously dissolved in hot water is added, the mixture thoroughly stirred, washed out and pressed. The thick gray mass obtained is then mixed with about 90 kg of linseed oil stirred and left through the oil color mill.
