Die vorliegende Erfindung bezieht sich auf Korrosionsschutzgemische mit einer überwiegenden Menge eines mineralischen Schmieröls oder filmbildender Stoffe, wie Wachse, Harze oder Petrolatum, gegebenenfalls unter Zusatz von organischen Lösungsmitteln, die außerdem noch 0,1 bis 3% öllöslicher Alkali- oder Erdalkali-Erdölsulfonate und 0,01 bis 3% eines Amidoamins oder Imidazolinderivats, das durch Umsetzung einer C8- bis Cu-Fettsäure mit Äthylendiamin oder Diäthylentriamin erhalten worden ist, enthalten.
Amidoamine und Imidazolinderivate der hierfür in Frage kommenden Art leiten sich von den genannten Fettsäuren und dem Äthylendiamin oder Diäthylentriamin dadurch ab, daß man zunächst Monosalze der Polyamine mit den Fettsäuren herstellt und daraus durch Wasserabspaltung das einfache Amidoamin gewinnt. Durch weitere Anlagerung von Fettsäure und weitere Wasserabspaltung erhält man dann noch die entsprechenden Di- und Triamidoamine. Im Falle der Ölsäure kommen also als Amidoamine in Frage das Oleylamidoäthylamin und ihr entsprechendes Oleat sowie das Dioleylamidoäthan. Noch andere Verbindungen dieser Art erhält man dadurch, daß man das Oleylamidoäthylamin bei etwas höhereren Temperaturen, z. B. bei 200 bis 2500C, unter Ringschluß dehydratisiert;
C17H33 -CO-NH- C2H4 · NH2 -
Für die Herstellung von Verbindungen der obigen Arten kommen alle gesättigten oder ungesättigten Fettsäuren mit 8 bis 24 Kohlenstoffatomen in Betracht, die auch eine oder mehrere Hydroxylgruppen enthalten können. Meist bevorzugt man als Fettsäuren Laurin-, Palmitin-, Stearin-, Öl-, Linol-, Rizinol-, Elaeomargarin-, Eruca-, Behen-, Erdnußöloder Lignocerinsäure.
Die Herstellung der obenerwähnten Amidoamine und Imidazolinderivate ist jedoch nicht Gegenstand der vorliegenden Erfindung.
Die Kohlenwasserstofföle, denen die Zusatzstoffe einverleibt werden, können von beliebiger Art sein, wenn nur die Zusätze darin löslich sind; z. B. sind Erdölfraktionen geeignet.
Es sind vorzugsweise mineralische Schmieröle, die man dazu benutzt, um ein Verrosten unzugänglicher Anlagen oder von Metallteilen während ihrer Bearbeitung oder Lagerung zu verhindern. Erfindungs-Korrosionsschutzgemische

gemäße Gemische mit Schmierölgehalten sind sehr vorteilhaft für solche Einrichtungen verwendbar, bei denen es außer auf Korrosionsschutz noch auf Schmierung ankommt, z. B. in Anlagen mit Umlaufführung von Öl, oder für Wasseranlagen, Lager, Instrumente oder Verbrennungskraftmaschinen.
Bei einer anderen Anwendungsart verleibt man die erfindunsgemäßen Korrosionsschutzzusätze filmbildenden Stoffen, wie Wachsen, Harzen oder Petroleum, gegebenenfalls in Gegenwart von flüchtigen organischen Lösungsmitteln, ein. Bringt man derartige Gemische auf eine metallische Fläche, so verdampft das flüchtige Lösungsmittel innerhalb kurzer Zeit und hinterläßt eine dünne Schicht, die ein Verrosten des Metalls verhütet.
Ein besonderer Vorteil der Gemische nach vorliegender Erfindung besteht darin, daß sie aschefrei sind, d.h., daß sie, beispielsweise auf Metalloberflächen aufgetragen, völlig verbrennen und keine

metallhaltigen Abscheidungen bilden, wenn diese geglüht werden.
Der Zusatz von Sulfonaten einerseits und von Aminderivaten andererseits (und zwar entweder von Fettaminen, also solchen Verbindungen, bei denen die Aminogruppen unmittelbar an der Kohlenstoffkette eines Alkylrestes sitzen, nämlich von Fettsäure-Amidoaminen, oder von Imidazolinen) ist zwar für Rostschutzzwecke schon bekanntgeworden, jedoch immer nur jeweils für eine dieser Arten von Zusatzstoffen allein. Demgegenüber hat es sich gezeigt, daß die gleichzeitige Anwendung dieser beiden Arten von Mitteln eine synergistische sehr wirksame Korrosionsschutzwirkung ergibt.
Es ist zwar auch bereits der Zusatz von Aminsalzen zusammen mit phosphor- und schwefelhaltigen oxydierten Verbindungen zu Leichtölen bekanntgeworden. Diese Gemische wirken einerseits reinigend und andererseits vor allem schmierend, haben jedoch nicht den Zweck des Korrosionsschutzes. Ähnliche Zusätze hat man auch schon zu Motortreibstoffen und zur Herstellung von Wasser-in-Öl-Emulsionen vorgeschlagen. Auch Imidazoline sind bereits als feste Korrosionsinhibitoren vorgeschlagen worden, jedoch nicht in Form von Korrosionsschutzgemischen zusammen mit mineralischen Schmierölen und öllöslichen Erdölsulfonaten.
Für Rostschutzzwecke hat man bisher nur die Zugabe von Sulfonaten und von Amin- oder Imidazolinderivaten jeweils für sich allein vorgeschlagen, jedoch nicht in Gemischen der eingangs genannten Art. Es hat sich gezeigt, daß bei gleichzeitigem Vorhandensem der Erdölsulfonate und der Amidoamine die Gesamtmenge dieser Zusätze in den Rostschutzgemischen sehr gering sein kann und doch eine Wirkung erreicht wird, die ebenso gut oder sogar besser als bei Verwendung der einzelnen Zusätze für sich allein ist. Dies wird durch das nachstehend aufgeführte Beispiel noch näher erläutert.
Beispiel
Es wurden Versuche mit Blechen aus warmgewalztem blankem Stahl durchgeführt, die mit den erfindungsgemäßen Rostschutzgemischen überzogen wurden. Für diese Versuchsreihe benutzte man Gemische, die als Grundöl ein naphthenisches Mineralöl mit einer Viskosität von 155 Centistoke bei 37° C enthielten. Die Zusammensetzung der erfmdungsgemäßen Mischungen geht aus der Tabelle unter Mischung V bis XI hervor. Als Kontrolle und zum Vergleich wurden das Grundöl allein (I) und Mischungen mit nur einem Zusatzbestandteil zum Grundöl herangezogen. Die Probell enthielt neben dem Grundöl 5% Dioleylamidoäthan, die Probe III statt dessen 5°/o Oleylamidoäthylaminoleat. Die Probe IV enthielt neben dem Grundöl nur 2,3 Vo Natriumsulfonat.
Die Stahlbleche wurden erst mit dem Sandstrahlgebläse gereinigt, dann mit den zu prüfenden Mischungen überzogen und 16 Stunden lang in einem Kasten unter den Bedingungen der Umgebung stabilisiert. Dann brachte man die Bleche in eine Befeuchtungskammer, wo sie voneinander getrennt aufrecht stehend einer dauernden Wasserdampfkondensation bei 37° C ausgesetzt wurden. Die Wirksamkeit der Rostschutzgemische wurde als diejenige geringste Zeit in Stunden ermittelt, nach der die ersten Zeichen von Rostbildung auf einem Blech sichtbar wurden. Die Ergebnisse dieses Versuchs sind in der Tabelle gezeigt, in der das Verhalten der Probebleche nach Aufbringen der erfindungsgemäßen Gemische und nach Aufbringen desselben Grundöls ohne Zu-
■ sätze oder mit nur jeweils einem der Zusatzbestandteile miteinander verglichen wird.

Aus diesen Versuchsergebnissen ist zu ersehen, daß zwar die Amidoaminverbindungen zur Hintanhaltung des Röstens von Stahlblechen bedeutend wirksamer als das freie Mineralöl waren, jedoch ist es nachteilig, daß man hierbei von den Amidoaminen allein recht erhebliche Mengen als Zusatz für die Mineralöle benötigt.
Wenn man hingegen den Kohlenwasserstoffölen außer den Amidoaminen noch kleinere Mengen öllöslicher Alkali- oder Erdalkalisulfonate einverleibt, so kann der Zusatz der teuren Amidoamine bzw. Imidazolinderivate bei gleicher Rostschutzwirkung wesentlich verringert werden.
Natürlich kann man den aus Kohlenwasserstoffölen bestehenden Grundmischungen außer den rostverhindernden Zusätzen noch andere Mittel, z. B. Farbstoffe, den Fließpunkt herabsetzende Zusätze, flüchtige Lösungsmittel, durch Wärmebehandlung verdickte fette Öle, sulfonierte fette Öle, Organo: metallverbindungen, metallische oder andere Seifen, Schlammzerteilungsmittel, Oxydationsverhütungsmittel, Verdickungsmittel, den Viskositätsindex verbessernde Mittel, andere Korrosionsschutzmittel, ölige Zusätze, Harze, Olefinpolymere, flüchtig gemachte fette Öle, Fettstoffe, Mineralöle, Wachse, Graphit oder Zinkoxyd einverleiben.
