Description

Die Erfindung bezieht sich auf eine Flüssigkeit für den Ein­ satz in zerspanenden Werkzeugmaschinen.The invention relates to a liquid for one set in cutting machine tools.

Aus der DE 32 47 426 A1 sind Schneidöle für die spangebende Bearbeitung von Buntmetallen auf Glykolbasis bekannt.From DE 32 47 426 A1 are cutting oils for the cutting Processing of non-ferrous metals based on glycol known.

Nach den heutigen Forderungen sollen sich Flüssigkeiten für den Einsatz in zerspanenden Werkzeugmaschinen gleichzeitig insbesondere durch gute Wärmeleitfähigkeit, guten Korrosions­ schutz, guten Verschleißschutz, gute Alterungsbeständigkeit, hohen Viskositätsindex, optimale Schwerentflammbarkeit sowie physiologische und ökologische Verträglichkeit für Mensch und Umwelt auszeichnen. Die bekannten Mineralöle, welche bisher als Zerspanungsflüssigkeit eingesetzt werden, können diesen Anforderungen in verschiedener Hinsicht jedoch nur teilweise genügen.According to today's demands, liquids should be used use in cutting machine tools at the same time especially due to good thermal conductivity, good corrosion protection, good wear protection, good aging resistance, high viscosity index, optimal flame retardancy as well physiological and ecological compatibility for humans and Mark the environment. The well-known mineral oils, which so far can be used as cutting fluid, this Requirements in various respects, however, only partially are enough.

Aufgabe der vorliegenden Erfindung ist es daher, eine Zer­ spanungsflüssigkeit vorzuschlagen, mit welcher die ange­ strebten Anforderungen besser erzielt werden können.The object of the present invention is therefore a Zer to propose cutting fluid with which the specified aspired requirements can be achieved better.

Diese Aufgabe wird erfindungsgemäß mit einer Multifunktions­ flüssigkeit nach Anspruch 1 gelöst.This object is achieved with a multifunction liquid dissolved according to claim 1.

Diese synthetische, transparente Flüssigkeit hat gegenüber Mineralölen eine um etwa 50% höhere Wärmeleitfähigkeit, verbunden mit sehr gutem Korrosionsschutzvermögen in Flüssig­ keits- und Dampfphase, gutem Verschleißschutz, sehr guter Alterungsbeständigkeit und sehr hohem Viskositätsindex (von etwa 160). Die erfindungsgemäße Zerspanungsflüssigkeit unterliegt nicht der Bildung von Bakterien, Hefen und Pilzen, es besteht keine Wassergefährdung (WGK 0) und eine gute biologische Abbaubarkeit (ca. 70% in 21 Tagen). Die erfin­ dungsgemäße Zerspanungsflüssigkeit ist ferner physiologisch unbedenklich. Die Toxizität der Aerosole ist unbedenklich und es entstehen keine gesundheitsschädlichen thermischen Zersetzungsprodukte. Es besteht ferner eine optimale Schwe­ rentflammbarkeit. Damit eignet sich die erfindungsgemäße Zerspanungsflüssigkeit überraschend gut für den Einsatz in zerspanenden Werkzeugmaschinen. Hierbei ist lediglich zu beachten, daß die mit ihr in Berührung kommenden Maschinen- und Anlagenteile Wasser-glykol-beständig sind. Als Inhibitoren kommen die insbesondere für den Verschleißschutz und den Korrosionsschutz solcher Flüssigkeiten üblicherweise einge­ setzten chemischen Stoffe in Betracht.This synthetic, transparent liquid has opposite Mineral oils have about 50% higher thermal conductivity,  combined with very good corrosion protection in liquid phase and vapor phase, good wear protection, very good Aging resistance and very high viscosity index (from about 160). The cutting fluid according to the invention is not subject to the formation of bacteria, yeast and fungi, there is no water hazard (WGK 0) and a good one biodegradability (approx. 70% in 21 days). The invent Cutting fluid according to the invention is also physiological harmless. The toxicity of the aerosols is harmless and there are no harmful thermal effects Decomposition products. There is also an optimal sweat flammability. The invention is therefore suitable Cutting fluid surprisingly good for use in cutting machine tools. This is only too note that the machine and System parts are water-glycol-resistant. As inhibitors come especially for wear protection and Corrosion protection of such liquids is usually turned on consider chemical substances.

Besonders optimale Zusammensetzungen der erfindungsgemäßen Zerspanungsflüssigkeit sind in den Ansprüchen 2 und 3 angegeben. Dabei bezieht sich Anspruch 3 auf eine monoethylen­ glykol-freie Multifunktionsflüssigkeit. Sie liegt damit diesbezüglich jedenfalls unter den inzwischen festgelegten MAK-Grenzwerten für Monoethylenglykol und ist besonders umweltschonend.Particularly optimal compositions of the invention Cutting fluid are in claims 2 and 3 specified. Claim 3 relates to a monoethylene glycol-free multifunctional liquid. It lies with it in this regard, at least among those that have now been established MAK limits for monoethylene glycol and is special environmentally friendly.
