Description

Metallputzmittel Die gebräuchlichen Metallputzmittel enthalten in der Regel Ölsäure oder deren Ammoniumsalze, als Metalloxyd lösende Mittel, wobei auch ihre netzenden und emulgierenden Eigenschaften die Wirkung der übrigen Zusätze, wie Kaolin, Lösungsmittel, Kieselerde, begünstigen.Metal cleaning agents The common metal cleaning agents contain in usually oleic acid or its ammonium salts, as a metal oxide solvent, whereby also their wetting and emulsifying properties the effect of the other additives, such as kaolin, solvents, silica, favor.

Es wurde nun gefunden, daß die Ölsäure bzw. deren Ammoniumsalze in Metallputzmitteln besser durch die Acylderlvate von Aminomonocarbonsäuren mit mindestens 6 C-Atomen im Fettsäurerest ersetzt werden. Die Verwendung dieser Produkte bietet den Vorteil, fettsparend zu sein, da die Produkte Fettsäuresubstitutionsprodukte sind, wobei der Fettanteil unter Berücksichtigung der sonst erforderlichen Menge an freier Fettsäure geringer ist. Ferner zeigen die Produkte durch den Stickstoffgehalt ein wesentlich besseres Metalloxydlösevermögen als die nicht substituierten Fettsäuren. Besonders wirken sich die Eigenschaften aus beim Reinigen von kupferhaltigen Legierungen. Beispiel I Ein flüssiges Metallputzmittel, bestehend aus 3,5 Teilen Oleylglycocoll, 2,5 Teilen Ammoniak, 25%ig, 2,5 Teilen Sprit, 2,5 Teilen Petroleum, I5 Teilen geschlämmter Kieselkreide, Ioo Teilen Wasser, wird mit einem Lappen auf die zu reinigende Metallfläche aufgebracht, verrieben und nachpoliert. Ein Vergleich mit einem Metallputzmittel gleicher Zusammensetzung, wobei jedoch statt der bezeichneten Aminocarbonsäure nur Ölsäure verwendet wird, ergibt einen nicht so guten Reinigungseffekt.It has now been found that the oleic acid or its ammonium salts in Metal cleaning agents better through the acyl derivatives of aminomonocarboxylic acids with at least 6 carbon atoms in the fatty acid residue are replaced. The use of these products offers the advantage of being fat-saving, as the products are fatty acid substitution products are, the fat content taking into account the otherwise required amount is lower in free fatty acid. Furthermore, the products show through the nitrogen content a much better metal oxide dissolving power than the unsubstituted fatty acids. The properties are particularly effective when cleaning alloys containing copper. Example I A liquid metal cleaning agent, consisting of 3.5 parts oleylglycocoll, 2.5 parts of ammonia, 25%, 2.5 parts of gasoline, 2.5 parts of petroleum, 15 parts of slurried Silica chalk, 100 parts of water, is applied to the metal surface to be cleaned with a cloth applied, rubbed and polished. A comparison with a metal cleaning agent same composition, but instead of the designated aminocarboxylic acid only When oleic acid is used, the cleaning effect is not so good.

Beispiele Eine Metallputzpaste, bestehend aus 6 Teilen Ceresin, -..Teilen Oleyiinethylam;inoessigsäure, 5o Teilen Kieselkreide, wird, wie üblich, auf dem zu reinigenden Metall verrieben und nachpoliert. Man beobachtet ein augenblickliches Lösen der Metalloxyde, z. B. von Kupfer, Zink, und erreicht durch Nachpolieren einen Hochglanz. Die Metallputznittel I gemäß der Erfindung sind auch, wie praktische Versuche erwiesen haben, denjenigen überlegen, welche Fettacylderivate von Aninostulfonsäuren mit mindestens 6 C Atomen im Fettsäurerest enthalten (größere Schonung der Metalloberfläche).Examples A metal plaster paste, consisting of 6 parts Ceresin, - .. parts Oleyiinethylam; inoacetic acid, 50 parts of siliceous chalk, is, as usual, on the Metal to be cleaned rubbed and polished. One observes an instant Dissolving the metal oxides, e.g. B. of copper, zinc, and achieved by polishing a Gloss. The metal cleaning agents I according to the invention are also as practical tests have shown, superior to those who use fatty acyl derivatives of aninostulfonic acids with at least 6 carbon atoms in the fatty acid residue (larger Protection of the metal surface).
