Description

Die Erfindung bezieht sich auf eine Flüssigkeit für den Einsatz in zerspanenden Werkzeugmaschinen. Derartige Flüssigkeiten sollen sich gleichzeitig insbesondere durch eine gute Wärmeleitfähigkeit, guten Korrosionsschutz, guten Verschleißschutz, gute Alterungsbeständigkeit, hohen Viskositätsindex, optimale Schwerentflammbarkeit sowie physiologische und ökologische Verträglichkeit für Mensch und Umwelt auszeichnen. Bekannte Mineralöle, welche bisher als Zerspanungsflüssigkeit eingesetzt werden, können diesen Anforderungen in verschiedener Hinsicht nur teilweise genügen.The invention relates to a fluid for use in cutting machine tools. Such fluids should be characterized in particular by good thermal conductivity, good corrosion protection, good wear protection, good ageing resistance, high viscosity index, optimal flame retardancy and physiological and ecological compatibility for humans and the environment. Known mineral oils that have been used as cutting fluids to date can only partially meet these requirements in various respects.

Aufgabe der vorliegenden Erfindung ist es daher, eine Zerspanungsflüssigkeit vorzuschlagen, mit welcher die angestrebten Anforderungen in besserer Weise erzielt werden können. The object of the present invention is therefore to propose a cutting fluid with which the desired requirements can be achieved in a better manner.

Diese Aufgabe wird erfindungsgemäß mit einer Multifunktionsflüssigkeit nach Anspruch 1 gelöst. Diese synthetische, transparente Flüssigkeit hat gegenüber Mineralölen eine um etwa 50% höhere Wärmeleitfähigkeit, verbunden mit einem sehr guten Korrosionsschutzvermögen in Flüssigkeits- und Dampfphase, gutem Verschleißschutz, sehr guter Alterungsbeständigkeit und einen sehr hohen 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 Abbaubar— keit (ca. 70% in 21 Tagen). Die erfindungsgemäße synthetische, transparente Zerspanungsflüssigkeit ist ferner physiologisch unbedenklich. Die Toxizität der Aerosole ist unbedenklich und es entstehen keine gesundheitsschädlichen thermischen Zersetzungsprodukte. Es besteht ferner eine optimale Schwerentflammbarkeit. Damit eignet sich die erfindungsgemäße Flüssigkeit überraschend gut für den Einsatz in zerspanendenThis object is achieved according to the invention with a multifunctional fluid according to claim 1. This synthetic, transparent fluid has a thermal conductivity that is about 50% higher than mineral oils, combined with very good corrosion protection in the liquid and vapor phase, good wear protection, very good aging resistance and a very high viscosity index (of about 160). The cutting fluid according to the invention is not subject to the formation of bacteria, yeasts and fungi, there is no water hazard (WGK 0) and good biodegradability (approx. 70% in 21 days). The synthetic, transparent cutting fluid according to the invention is also physiologically harmless. The toxicity of the aerosols is harmless and no harmful thermal decomposition products are formed. There is also optimal flame retardancy. The fluid according to the invention is therefore surprisingly well suited for use in cutting

Werkzeugmaschinen. Bei ihrem Einsatz 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 eingesetzten chemischen Stoffe in Betracht.Machine tools. When using it, it is only necessary to ensure that the machines and system components that come into contact with it are water-glycol resistant. The chemical substances that are usually used for wear protection and corrosion protection of such liquids can be considered as inhibitors.

Besonders optimale Zusammensetzungen der erfindungsgemäßen
Flüssigkeit sind in den Ansprüchen 2 und 3 angegeben. Dabei bezieht sich Anspruch 3 auf eine monoethylenglykol-freie Multifunktionsflüssigkeit. Sie liegt damit diesbezüglich jedenfalls unter den inzwischen festgelegten MAK-Grenzwerten für Monoethylenglykol und ist besonders umweltschonend.Particularly optimal compositions of the inventive
Liquids are specified in claims 2 and 3. Claim 3 refers to a monoethylene glycol-free multifunctional liquid. In this respect, it is therefore below the MAK limits for monoethylene glycol that have now been established and is particularly environmentally friendly.
