Definitions

  • the invention relates to an oil-in-water emulsion for cold rolling aluminum and aluminum alloys, with a hydrodynamic film former or reaction layer former, polyethoxylated sorbitan oleate as an emulsifier, unsaturated, long-chain alkyl monocarboxylic acids as an inhibitor against hydrogen embrittlement and rust formation, hexamethylene tetramine and stabilizer, fungus Bactericide and deionized water.
  • oil-in-water emulsions allow much better cooling due to the greater heat of evaporation of water and thus greater stitch reduction and / or increased rolling speed.
  • aqueous rolling agents pose greatly reduced exhaust air problems and are less dependent on oil. For this reason, many attempts have been made in the aluminum industry to use oil-in-water emulsions when cold rolling strips.
  • a major disadvantage of the oil-in-water emulsions belonging to the prior art is that the metal surface freshly produced by the rolling process reacts with water within a few seconds. This superficial corrosion attack as a result of the water phase leads to annoying spots on the belt surface. The reduced surface quality of a tape or film due to the formation of these so-called water stains is inadequate for many applications.
  • the inventor has set himself the task of creating an oil-in-water emulsion of the type mentioned at the beginning for cold rolling aluminum and aluminum alloys, with which the formation of water spots on the freshly rolled strip surface can be reduced.
  • the object is achieved in that the emulsion additionally contains 0.1 to 3 percent by weight of xylitol and sorbitol as inhibitors against water stain formation.
  • xylitol and sorbitol to an oil-in-water emulsion largely prevents the formation of water stains. It is therefore no longer absolutely necessary to remove the emulsion from the surface of the freshly rolled strips.
  • the inhibitor is already fully effective when 1000 parts by weight of the emulsion contain 1 to 30 parts by weight of xylitol and sorbitol.
  • the effect of the inhibitor composed of xylitol and sorbitol can be increased further by adding glycerol.
  • 1000 parts by weight of the emulsion contain 20 to 90 parts by weight of glycerin.

Description

  • Die Erfindung bezieht sich auf eine ÖI-in-Wasser-Emulsion zum Kaltwalzen von Aluminium und Aluminiumlegierungen, mit einem hydrodynamischen Filmbildner bzw. Reaktionsschichtbildner, polyäthoxylierten Sorbitanoleaten als Emulgator, ungesättigten, langkettigen Alkylmonocarbonsäuren als Inhibitor gegen Wasserstoffversprödung und Rostbildung, Hexamethylentetramin als Stabilisator, Fungicid und Baktericid sowie deionisiertem Wasser.
  • Verglichen mit Walzschmiermitteln auf Ölbasis ermöglichen Öl-in-Wasser-Emulsionen wegen der grösseren Verdampfungswärme von Wasser eine viel bessere Kühlung und damit eine grössere Stichabnahme und/oder erhöhte Walzgeschwindigkeit. Neben diesen rein wirtschaftlichen Faktoren, die Rationalisierungsbestrebungen weitgehend entgegenkommen, muss weiter berücksichtigt werden, dass wässrige Walzmittel stark verminderte Abluftprobleme stellen und weniger vom Erdöl abhängig sind. Deshalb sind in der Aluminiumindustrie schon viele Versuche unternommen worden, beim Kaltwalzen von Bändern ÖI-in-Wasser-Emulsionen einzusetzen.
  • Aus der DE-AS 26 32 142 ist eine ÖI-in-Wasser-Emulsion zum Kaltwalzen von Leichtmetallen bekannt, die Alkylmonocarbonsäureester als Reaktionsschichtbildner, Polyisobutylen als hydrodynamischen Filmbildner, polyäthoxylierte Sorbitanoleate als Emulgator, ungesättigte, langkettige Alkylmonocarbonsäuren als Inhibitor gegen Wasserstoffversprödung und Rostbildung, Hexamethylentetramin als Stabilisator, Fungicid und Baktericid, Rest deionisiertes Wasser enthält.
  • Ein wesentlicher Nachteil der dem Stand der Technik zugehörigen ÖI-in-Wasser-Emulsionen liegt darin, dass die durch den Walzvorgang frisch erzeugte Metalloberfläche innerhalb weniger Sekunden mit Wasser reagiert. Dieser oberflächliche Korrosionsangriff als Folge der Wasserphase führt zu störenden Flecken auf der Bandoberfläche. Die durch die Bildung dieser sogenannten Wasserflecken verminderte Oberflächenqualität eines Bandes bzw. einer Folie ist für viele Anwendungszwecke ungenügend. Es ist deshalb bei Anwendung der bekannten Öl-in-Wasser-Emulsionen unbedingt erforderlich, die Emulsion unmittelbar nach dem Austritt des Bandes aus dem Walzwerk beispielsweise durch Abblasen mit Druckluft möglichst vollständig von der gewalzten Bandoberfläche zu entfernen.
  • Aus der FR-A-2 391 261 ist es bekannt, Kaltwalzemulsionen zur Verarbeitung von Aluminium und Aluminiumlegierungen Polyole mit einer 6-C-Atom-Kette, beispielsweise Sorbitol, als Korrosionsinhibitoren beizugeben. Die Verminderung der Wasserflecken oben beschriebener Art ist damit jedoch nicht im gewünschten Masse erreichbar.
  • Angesichts dieser Gegebenheiten hat sich der Erfinder die Aufgabe gestellt, eine ÖI-in-Wasser-Emulsion der eingangs erwähnten Art zum Kaltwalzen von Aluminium und Aluminiumlegierungen zu schaffen, mit welcher die Bildung von Wasserflecken auf der frisch gewalzten Bandoberfläche vermindert werden kann.
  • Die Aufgabe wird erfindungsgemäss dadurch gelöst, dass die Emulsion zusätzlich als Inhibitor gegen Wasserfleckenbildung je 0.1 bis 3 Gewichtsprozente Xylit und Sorbit enthält.
  • Durch den gemeinsamen Zusatz von Xylit und Sorbit zu einer Öl-in-Wasser-Emulsion wird die Bildung von Wasserflecken weitgehend unterbunden. Ein Entfernen der Emulsion von der Oberfläche der frisch gewalzten Bänder ist somit nicht mehr unbedingt erforderlich. Der Inhibitor ist bereits voll wirksam, wenn 1000 Gewichtsteile der Emulsion je 1 bis 30 Gewichtsteile Xylit und Sorbit enthalten.
  • Es hat sich des weiteren herausgestellt, dass die Wirkung des aus Xylit und Sorbit zusammengesetzten Inhibitors durch die Zugabe von Glycerin noch gesteigert werden kann. Vorteilhafterweise enthalten 1000 Gewichtsteile der Emulsion 20 bis 90 Gewichtsteile Glycerin.
  • Der Zusatz von Xylit, Sorbit und gegebenenfalls Glycerin beeinflusst den Walzvorgang nicht und führt bei einer anschliessenden Glühung der gewalzten Bänder auch nicht zu Rückständen auf der Bandoberfläche.
  • Die Vorteilhaftigkeit des erfindungsgemässen Zusatzes des Inhibitors gegen Wasserfleckenbildung geht aus den Versuchen mit den nachstehend angeführten Kaltwalzemulsionen hervor.

    Figure imgb0002
  • Die organischen Komponenten wurden bei Raumtemperatur unter einfachem Rühren zusammengegeben und mit deionisiertem Wasser versetzt. Die beiden getrennten Phasen wurden anschliessend in einer Emulgiermaschine zu einer Emulsion verarbeitet.
  • Mit den vorstehend genannten Emulsionen wurden auf einem Einzelquartogerüst Kaltwalzversuche mit Aluminium der Reinheit AI 99,2 durchgeführt. Die Stichabnahmen betrugen teilweise bis zu 92%. An den gewalzten Aluminiumbändern konnten in keinem Fall Anzeichen von Wasserfleckenbildung beobachtet werden. Ebenso führte keine der Emulsionen bei einer anschliessenden Glühung der gewalzten Bänder zu Rückständen auf der Bandoberfläche.
