Description

Schwärze zur Nachbehandlung von Phosphatoberflächenschichten Es ist bekannt, Phosphatschichten, die zur Verbesserung des Korrosionsschutzes auf Metallen, insbesondere Eisen, erzeugt sind, einzuschwärzen. Die hierfür bisher verwendeten Schwärzen zeigen jedoch bei einer derartigen Nachbehandlung von Phosphatschichten gewisse Nachteile. Sie ziehen z. B. nicht immer gleichmäßig auf den P'hosphatschichten auf. Außerdem sind sic noch nicht allen Anforderungen in bezug auf Abrieb-, Öl- und Wasserfestigkeit gewachsen.Blackness for post-treatment of phosphate surface layers It is known, phosphate layers that improve the corrosion protection on metals, in particular iron, are produced to be blackened. The ones previously used for this However, they show blackening with such an aftertreatment of phosphate layers certain disadvantages. You pull z. B. not always evenly on the phosphate layers on. In addition, they have not yet met all of the requirements relating to abrasion, oil and water resistance.

Gegenstand der Erfindung ist -nun eine Schwärze zur Nachbehandlung von Phosphatoberflächenschichten, mit Hilfe deren erhebliche Verbesserungen in bezug auf die obengenannten Nachteile erzielt werden.The subject of the invention is now a blackness for aftertreatment of phosphate surface layers, with the help of their considerable improvements in relation to on the above disadvantages can be achieved.

Die Schwärze besteht aus einem Lösungsgemisch von Trichloräthylen und Sprit in Mengen von zusammen etwa 9o bis 95%, einem echt löslichen schwarzen organischem Farbstoff in Mengen von 2 bis 4a/o und einem Gemisch von Polyvinylacetat und Kunstschellack in Mengen von insgesamt 3 bis 6%, vorzugsweise 4 bis 5%.The blackness consists of a mixed solution of trichlorethylene and fuel in amounts totaling about 90 to 95%, a truly soluble black organic dye in amounts of 2 to 4 a / o and a mixture of polyvinyl acetate and artificial shellac in amounts totaling 3 to 6%, preferably 4 to 5%.

Das Verhältnis von Trichloräthvlen und Sprit zueinander soll dabei innerhalb von 5 : I bis io : I liegen, es beträgt vorzugsweise 9 : I .The ratio of Trichloräthvlen and fuel to each other should be are within 5: I to 10: I, it is preferably 9: I.

Die Schwärze gemäß Erfindung zieht der p'hosphatierten Oberfläche vollkommen gleichmäßig auf, zeigt ein intensives lackähnliches Schwarz und hat gute Abrieb-, Öl- und Wasserfestigkeit.The blackness according to the invention pulls the phosphated surface completely evenly, shows an intense lacquer-like black and has good Abrasion, oil and water resistance.

Als Beispiel sei folgende Zusammensetzung genannt: 82,6% Trichloräfhylen, 3,70/0 Polyvinylacetat, 3,o 0,'o spritlösliches Nigr osinschwarz, ,9, 2 % Sprit, I, 5 0`0, Kunstschellack KR.The following composition is mentioned as an example: 82.6% trichlorethylene, 3.70 / 0 polyvinyl acetate, 3, o 0, 'o fuel-soluble nigr osin black,, 9, 2% fuel, I, 5 0`0, artificial shellac KR.
