Abstract
Description
Die vorliegende Erfindung betrifft die Verwendung von Phosphonsäurederivaten in wasserhaltigen Schmier- und Kühlschmierstoffen und Zusammensetzungen, die diese enthalten.The present invention relates to the use of phosphonic acid derivatives in water-based lubricants and cooling lubricants and compositions, that contain them.
Bei der Bearbeitung metallischer Werkstoffe, wie Bohren, Schneiden, Fräsen und Stanzen, werden Kühlschmierstoffe verwendet, um den Verschleiß der Bearbeitungswerkzeuge so gering wie möglich zu halten. Als Kühlschmierstoffe hat sich eine Vielzahl von chemischen Verbindungen bewährt, welche in Formulierungen mit sogenannten Grundölen, wie beispielsweise Mineralölen, Polyethylen- und Polypropylenglykolen und Fettsäureestern, Anwendung finden. Als verschleißmindernde Komponenten sind Chlorparaffine, chlorierte Carbonsäureglyzeride, Phosphorsäureester, Zinkdialkyldithiophosphate, verschiedene Schwermetallsulfide und andere mehr bekannt. Alle diese genannten Verbindungsklassen werden in wasserunlöslichen Formulierungen angewendet. Auf Grund der verschärften Vorschriften im Umweltschutz wird der Einsatz dieser Verbindungsklassen zunehmend schwieriger, einige davon wurden sogar mittlerweile als Schadstoffe deklariert, andere neigen zur Bildung krebserzeugender N-Nitrosoamine oder bei thermischer Belastung zur Bildung von Benzo(a)pyren. (Lit.: "Kühlschmierstoffe", Sonderausgabe des Mitteilungsblattes "sicher arbeiten" der Maschinenbau- und Metall-Berufsgenossenschaft, 3. Auflage Februar 1993).When processing metallic materials such as drilling, cutting, milling and punching, cooling lubricants are used to reduce the wear of the machining tools to keep it as low as possible. A large number of chemical coolants have been found Compounds proven, which in formulations with so-called base oils, such as for example mineral oils, polyethylene and polypropylene glycols and fatty acid esters, Find application. Chlorine paraffins are chlorinated as wear-reducing components Carboxylic acid glycerides, phosphoric acid esters, zinc dialkyldithiophosphates, various Heavy metal sulfides and others more well known. All of these classes of compounds mentioned are used in water-insoluble formulations. Because of the tightened Environmental protection regulations are increasingly using these classes of compounds more difficult, some of them have even been declared as pollutants, others tend to form carcinogenic N-nitrosoamines or when exposed to heat Formation of benzo (a) pyrene. (Lit .: "Cooling lubricants", special edition of the Newsletter "work safely" of the mechanical engineering and metal trade association, 3rd edition February 1993).
Das derzeit am häufigsten verwendete und preiswerteste Kühlschmiermittel ist zweifellos Chlorparaffin, welches unverdünnt oder im Gemisch mit den erwähnten Grundölen zum Einsatz kommt. Die Entfernung dieser Kühlschmierstoffe vom bearbeiteten Werkstück war solange unproblematisch, wie die Reinigungsanlagen mit Lösungsmitteln auf Basis von Chlorkohlenwasserstoffen (beispielsweise Perchlorethylen oder Trichlorethylen) betrieben wurden. Die Reinigungsflotten wurden durch Destillation wieder aufbereitet und der Destillationssumpf konnte als Sondermüll entsorgt werden. The most commonly used and inexpensive cooling lubricant is undoubtedly Chlorinated paraffin, which is undiluted or mixed with the base oils mentioned for Commitment comes. The removal of these coolants from the machined workpiece was as long as unproblematic as the cleaning systems with solvents based on Chlorinated hydrocarbons (for example perchlorethylene or trichlorethylene) operated were. The cleaning liquors were reprocessed by distillation and the Distillation sump could be disposed of as special waste.
Mit Inkrafttreten der TA-Luft im Jahre 1986 und der damit verbundenen drastischen Reglementierungen von Emissionen in die Luft, wurden Reinigungsanlagen auf Basis von Chlorkohlenwasserstoffen von Reinigungssystemen auf Tensid-Basis abgelöst. Die Effektivität ist allerdings bei weitem nicht so hoch wie bei Lösungsmittelsystemen und kann deshalb nur mit Hilfe mehrerer Reinigungszyklen erreicht werden.With the entry into force of TA-Luft in 1986 and the associated drastic Regulations of emissions to air, were based on cleaning systems Chlorinated hydrocarbons replaced by surfactant-based cleaning systems. The However, effectiveness is nowhere near as high as with solvent systems and can can therefore only be achieved with the help of several cleaning cycles.
Zu den technischen Schwierigkeiten bei der Reinigung der unter Verwendung von Chlorparaffinen bearbeiteten Werkstücke treten außerdem noch andere umweltrelevante Aspekte auf. Chlorparaffine haben sich auf Grund ihres breiten Anwendungsspektrums weltweit in Gewässern und deren Sedimenten verteilt (VDI-Nachrichten Nr. 21, 26. Mai 1995).The technical difficulties in cleaning the using Workpieces machined with chlorine paraffins also have other environmentally relevant effects Aspects on. Chlorinated paraffins have a wide range of uses distributed worldwide in waters and their sediments (VDI News No. 21, May 26 1995).
Der Großteil der kurzkettigen Chlorparaffine stammt aus dem Bereich der Metallbearbeitung. Sie belasten die Ökosysteme auch auf Grund ihres nur sehr langsamen biologischen Abbaus in der Natur und lassen sich unter anderem in der Nahrungsmittelkette eindeutig nachweisen. Die Verbindungsklasse der Chlorparaffine wurde außerdem zwischenzeitlich in die Liste der gefährlichen Arbeitsstoffe (MAK-Liste) aufgenommen und in die Gruppe III B eingeordnet (" begründeter Verdacht auf krebserregendes Potential"). Alle diese Fakten zeigen auf, wie notwendig die vollständige Substitution der Chlorparaffine in ihrer technischen Anwendung ist.The majority of the short-chain chlorinated paraffins comes from the area of Metalworking. They also burden the ecosystems because of their very slow nature biodegradation in nature and can be found, among other things, in the food chain clearly prove. The class of compounds of chlorinated paraffins also became meanwhile included in the list of hazardous substances (MAK list) and classified in group III B ("reasonable suspicion of carcinogenic potential"). All these facts show how necessary the complete substitution of chlorinated paraffins is in their technical application.
Die Verwendung von Polyethylen- und Polypropylenglykolen in Substanz oder in Form von wäßrigen Lösungen als Kühlschmiermittel, weist nicht diese technischen, ökologischen und medizinischen Nachteile auf. Sie sind vom Werkstück leicht entfernbar, biologisch leicht abbaubar und auch nicht gesundheitsgefährdend. Neben ihrer guten Schmierwirkung und ihrem hohen Benetzungsvermögen zeigen sie eine gute Verträglichkeit mit anionischen und kationischen Verbindungen. Nachteilig wirkt sich hingegen ihre begrenzte Temperaturstabilität aus, was die Verwendung von Additiven notwendig macht, welche die Thermostabilität der Polyglykole wesentlich erhöht.The use of polyethylene and polypropylene glycols in bulk or in the form of aqueous solutions as cooling lubricants, does not have these technical, ecological and medical disadvantages. They are easily removable from the workpiece, and are biologically light degradable and also not hazardous to health. In addition to their good lubricating properties and their high wetting capacity shows a good compatibility with anionic and cationic compounds. However, their limited effect has a disadvantage Temperature stability, which makes the use of additives necessary, which the Thermostability of the polyglycols increased significantly.
Für diesen Einsatzzweck werden Verbindungen wie Phenothiazin, Phenyl-α-Naphthylamin, 2,6-Di-t-butyl-4-methylphenol, Tocopherol, Di-n-oktylphosphit, Triphenylphosphit und andere verwendet. Fast alle diese Verbindungen sind toxikologisch bedenklich, und ihre biologische Eliminierbarkeit ist sehr gering. Eine Entsorgung dieser Kühlschmiermittel über öffentliche Kläranlagen ist infolgedessen äußerst problematisch, wenn nicht gar unmöglich. Somit ergibt sich die Forderung nach Kühlschmiermitteln, welche - gegebenenfalls unter Erneuerung verbrauchter Komponenten - wieder im Kreislauf verwendet werden können, deren Wirksubstanzen somit auch bei hohen Temperaturen nicht oxidativ abgebaut werden und dadurch keine schädlichen Abbauprodukte bilden.For this purpose, compounds such as phenothiazine, phenyl-α-naphthylamine, 2,6-di-t-butyl-4-methylphenol, tocopherol, di-n-octyl phosphite, triphenyl phosphite and others used. Almost all of these compounds are toxicologically unsafe, and theirs biological eliminability is very low. Dispose of this coolant over As a result, public wastewater treatment plants are extremely problematic, if not impossible. This results in the demand for cooling lubricants, which - if necessary under Renewal of used components - can be used again in the cycle, their active substances are therefore not oxidatively degraded even at high temperatures and therefore do not form any harmful degradation products.
Aufgabe der vorliegenden Erfindung war daher die Bereitstellung eines Kühlschmierstoffes für die Metallverarbeitung und einer Zusammensetzung, die diesen Kühlschmierstoff enthält. Diese Kühlschmierstoffe sollen die folgenden Eigenschaften:The object of the present invention was therefore to provide a Cooling lubricant for metal processing and a composition that contains this coolant. These cooling lubricants are said to be the following Properties:

- - eine hohe Thermostabilität,- high thermal stability,
- - toxikologische Unbedenklichkeit aufweisen.- have toxicological safety.
Darüber hinaus sollten sie wasserlöslich oderThey should also be water soluble or
- - selbst emulgierend und- self emulsifying and
- - biologisch eliminierbar sein.- be biologically eliminable.
