Patentschrift stimmt mit der Auslegeschrift überein
Wäßrige Metallbearbeitungsflüssigkeiten sind bereits bekannt.
Zu den Anforderungen an solche Metallbearbeitungsfiüssigkeiten gehören korrosionshemmende Eigenschaften für eisenhaltige und kupferhaltige Legierungen sowie Beständigkeit unter den Arbeitsbedingungen. Weiterhin dürfen sich nach der Metallbearbeitung keine Rückstände auf dem Werkzeug und dem Werkstück ergeben. Weitere Anforderungen sind: Vermeidung einer übermäßigen Schaumbildung, ίο Beständigkeit gegen Ranzigwerden und Verwendbarkeit in Lösungen mit hartem Wasser, so daß keine Ausfällung von Bestandteilen eintritt. Die bisher bekannten Mittel haben jedoch nicht alle vorstehend aufgeführten Anforderungen in zufriedenstellender Weise erfüllt. ,
Es wurde nun gefunden, daß diese Eigenschaften durch eine Metallbearbeitungsflüssigkeit erzielt werden, welche eine Kombination von drei je einzeln als Schmierölzusätze bekannten Komponenten, nämlich 5 bis 40 Gewichtsprozent eines Alkanolamine, 0,1 bis 9 Gewichtsprozent einer Carbonsäure mit 6 bis 12 Kohlenstoffatomen und 0,1 bis 9 Gewichtsprozent einer Alkenylbernsteinsäure bzw. deren Anhydrid, wobei der Alkenylrest gerad- oder verzweigtkettig oder durch Wasserstoff, Schwefel oder Halogen substituiert sein kann, enthält.
Als Alkanolamine.werden solche, wie Mono-, Dioder Triäthanolamin oder Isopropandlamine und Methyldiäthanolamin oder auch Gemische derselben verwendet.
Als Säuren werden solche mit mittlerem Molekulargewicht, nämlich .mit 6 bis 12 Kohlenstoffatomen je Molekül verwendet. Es können gesättigte oder ungesättigte Säuren oder Mischungen sein. Bevorzugt sind Säuren mittleren Molekulargewichts, wie önanthsäure, Caprylsäure, Caprinsäure, Pelargonsäure, Capronsäure, Undecylensäure, Undecylsäure und Laurinsäure.

Beispiele sind: Äthenylbernsteinsäureanhydrid, Äthenylbernsteinsäure, Äthylbernsteinsäureanhydrid, Propenylbernsteinsäureanhydrid, sulfuriertes Propenylbernsteinsäureanhydrid, Butenylbernsteinsäure, 2 - Methylbutenylbernsteinsäureanhydrid, 1,2-Dichlorpentylbernsteinsäureanhydrid, Hexenylbernsteinsäureanhydrid, Hexylbernsteinsäure, sulfuriertes 3 - Methylpentenylbernsteinsäureanhydrid, 2,3-Dimethylbutenylbernsteinsäureanhydrid, 3,3-Dimethylbutenylbernsteinsäure, 1,2-Dibrom-2-äthylbutylbernsteirisäure, Heptenylbernsteinsäureanhydrid, 1,2-Dijodoctylbernsteinsäure, Octenylbernsteinsäureanhydrid, Diisobutenylbernsteinsäureanhydrid, 2-Methylheptenylbernsteinsäureanhydrid, 4-Äthylhexenylbernsteinsäure, 2-Isopropylpentenylbernsteinsäureanhydrid, Nonenylbernsteinsäureanhydrid, 2 - Propylhexenylbernsteinsäureanhydrid, Decenylbernsteinsäure, Decenylbernsteinsäureanhydrid,

Die Verfahren zur Herstellung der Alkenylbernsteinsäureanhydride sind bekannt. Ein geeignetes Verfahren bedient sich der Reaktion eines Olefins mit Maleinsäureanhydrid.
Alkenylbernsteinsäuren bzw. deren Anhydride mit 8 bis 12 Kohlenstoffatomen je Molekül werden bevorzugt. Weiter können andere übliche Zusätze beigegeben werden, z. B. Alkalinitrite oder Natriumsalze von Mercaptobenzothiazol, Phenole, wie Natriumsalze von Orthophenylphenol, chlorierten Phenolen, oder Borsäure und Boroxyde oder Alkalihydroxyd oder Chelatbildungsmittel, wie das Natriumsalz von D'iäthylentriaminpentaessigsäure 'oder Salze von Äthylendiamintetraessigsäure oder Nitrilotriessigsäure.
Die Mengenverhältnisse der Kombination sind: Alkanolamin 5 bis 40 Gewichtsprozent, vorzugsweise 20 bis 35 Gewichtsprozent, die Säure 0,1 bis 9 Gewichtsprozent, vorzugsweise 1 bis 4 Gewichtsprozent, die Alkenylbernsteinsäure bzw. deren Anhydrid' 0,1 bis 9 Gewichtsprozent, vorzugsweise 0,1 bis 4 Gewichtsprozent. .
' Die Metallbearbeitungsflüssigkeit wird wie üblich durch einfaches Mischen der Komponenten mit 10 bis 20 Teilen Wasser hergestellt. Anschließend kann weiteres Wasser zugegeben werden.
Die verbesserten Eigenschaften der beanspruchten Kombination bei Vergleich mit den Einzelkomponenten sind aus den nachfolgenden Beispielen ersichtlich.
Korrosionstest
Schmiedeeisenstückchen wurden in einen 50-ml-Becher eingebracht, zusammen mit dem zu untersuchenden Medium. Dann wurde alle überschüssige Flüssigkeit abgegossen, und der Becher wurde in einer Atmosphäre mit einer relativen Feuchtigkeit von etwa 90% bei einer Temperatur von etwa 21 bis 24° C abgestellt. Nach einem Lagerzeitraum von 48 Stunden wurde die Probe dann auf das Auftreten von Rost geprüft.
Wirksamkeit bei maschinellen
Bearbeitungsvorgängen
Die Wirksamkeit bei maschinellen Bearbeitungsvorgängen wurde in Verbindung mit einer Reihe von Löchern, die in einen Prüfstab aus heiß gewalztem Stahl gebohrt waren und in die ein Gewinde einzuschneiden war, festgestellt. Vor der Prüfung wurden Proben unter Verwendung von 1 Gewichtsteil des Additivkonzentrats auf 5 Gewichtsteile destilliertes Wasser verdünnt. Die Flüssigkeit wurde dem Gewindebohrloch mit einer Polyäthylenquetschflasche zugeführt. Vier unbekannte Proben waren von zwei Standardproben umschlossen und wurden mit diesen verglichen. Die Gewindebohrwirksamkeit wurde berechnet, indem die bei den unbekannten Proben ermittelte Drehkraft durch die mittlere Drehkraft bei den Standardproben geteilt und mit 100 multipliziert wurde.
