Definitions
- metal cutting is understood to mean machining operations in which the shape of a piece of metal is changed by removing material from the workpiece to be machined with a machining tool. Examples of such metal machining processes are drilling, turning, milling and grinding. For such machining operations it is necessary to rinse the tool and workpiece with a liquid cooling lubricant, which has the following functions: lubricating the tool to avoid welding and overheating, dissipating the heat generated and removing the chips or other metal particles that are formed. that it prevents corrosion of the workpiece.
- oils, oil-in-water emulsions or water-soluble cooling lubricants which consist only of an aqueous solution are known as cooling lubricants.
- the present invention is concerned with such water-soluble Lubricants, i.e. cooling lubricants that do not contain water-insoluble components such as oils.
- the cleaner Depending on the load with cooling lubricant, the cleaner must either be replenished with new cleaning-active components, regenerated by bath care measures or discarded and re-prepared leads to a high consumption of detergent active ingredients, which must be disposed of at the end of the service life of the detergent, which has an environmental impact and is also economically disadvantageous due to the required use of materials.
- the invention has for its object to provide a Nerfahrkombination for metal cutting using an aqueous cooling lubricant and subsequent cleaning of the processed metal parts with an aqueous cleaning solution, in which the ingredients of the cooling lubricant and the aqueous cleaning solution are matched so that the ingredients of the Cooling lubricant supplement the cleaning solution or at least not negatively influence it.
- the cooling lubricant does not represent a "dirt load" for the cleaner, but rather complements it. This enables the cleaning solution itself to use less active ingredients.
- the service life of the cleaning solution is extended even without bathroom care measures Lower disposal costs relieve the environment and make the entire process cheaper.
- the invention is based on aqueous ("water-soluble") cooling lubricants which contain polyglycol monoether and / or polyglycol diether as the lubricating component.
- aqueous cooling lubricants contain corrosion inhibitors.
- German patent application DE 197 23 990.0 discloses cleaning agents for metal cleaning. the glycol monoethers of the general formula as cleaning-active components
- glycol monoethers are used in combination with cationic surfactants in a weight ratio of glycol monoether to cationic surfactant between 8: 1 and 100: 1.
- This cleaner preferably contains corrosion inhibitors as further active ingredients.
- the object of the invention is achieved by a method for metal cutting using an aqueous cooling lubricant and subsequent cleaning of the machined metal parts with an aqueous cleaning solution, characterized in that
- a) uses an aqueous solution as cooling lubricant for metal cutting, which contains corrosion inhibitors and polyglycol monoether and / or polyglycol diether, and
- an aqueous solution is used as the cleaning solution which contains cleaning-active substances and the same corrosion inhibitors as the cooling lubricant.
- the lubricating polyglycol monoethers or polyglycol diethers are selected so that they are compatible with the components of the cleaning solution. They therefore do not cause any loss of the cleaning action, nor do they impair the effectiveness of the corrosion inhibitors of the cleaning solution. So they do not represent contamination for the cleaning solution and therefore do not require any bath care measures to remove them. Rather, a steady content of these components occurs in the cleaning solution during operation, since the same amounts of lubricants are carried into the cleaning solution in equilibrium as are discharged through the cleaned metal parts.
- polyglycol monoethers or polyglycol diethers to be used as lubricating components in the cooling lubricant are known as such for this use and are commercially available.
- the polyglycol monoethers are also frequently shortened, but incorrectly, referred to as “polyglycols”. They are obtained by reacting suitable starting molecules, for example monohydric or polyhydric alcohols having 1 to 5 carbon atoms, with ethylene oxide and / or propylene oxide become. This creates a polyethylene glycol, polypropylene glycol or a mixed chain in which the alkylene oxide units are linked to form polyethers after the ring has been opened. In the term "polyglycols", however, these ether bonds are generally disregarded.
- glycol monoethers or polyglycol monoethers are oligomeric or polymeric polyalkylene glycol chains which are at one end
- glycol diether or polyglycol diether mean oligomeric or polymeric alkylene glycol chains which are etherified with alcohols at both ends, and it is not necessary for the molecules to carry the same alcohol groups at both ends.
- glycol diether or “polyglycol diether” chosen here corresponds to This means that the term “end group-closed glycol or polyglycol ether” can also be found in technology.
- the aqueous cooling lubricant to be used according to the invention preferably contains those polyglycol monoethers and / or polyglycol diethers which can be obtained by ethoxylation and / or propoxylation of mono- or polyhydric alcohols having 1 to 5 carbon atoms.
- the polyalkylene glycol chains are closed at the other end with alcohols with 1 to 6 carbon atoms.
- the polyglycol monoethers or diethers preferably have an average molecular weight in the range from 500 to 25,000.
- the corrosion inhibitors which are used according to the invention both in the aqueous cooling lubricant and in the aqueous cleaning solution are preferably selected from alkanolamines and / or from salts of branched or unbranched, saturated or unsaturated aliphatic mono- or dicarboxylic acids with 6 to 10 carbon atoms and / or from aromatic carboxylic acids with 7 to 10 carbon atoms. If this refers to alkanolamines and salts of carboxylic acids, this can mean, on the one hand, that the alkanolamine salts of the carboxylic acids are used directly. This is equivalent to a mixture of alkanolamines and carboxylic acids that react with one another to form salts.
- the alkanolamines can be used as such, the carboxylic acids as alkali metal salts. Mixtures of carboxylic acids and alkali metal hydroxides are equivalent to alkali metal salts of carboxylic acids.
- the alkanolamines and / or the carboxylic acids will be present as an equilibrium mixture of the neutral molecules and the cations in the case of the alkanolamines or the anions in the case of the carboxylic acids.
- the ready-to-use aqueous cooling lubricant preferably contains 2 to 15 g / 1 polyglycol monoether and / or polyglycol diether and 8 to 40 g / 1 corrosion inhibitors.
- the aqueous cooling lubricant can additionally contain emulsifiers, buffer substances, surfactants and / or biocides as further components. Its pH is preferably in the range between about 6 and about 9.5.
- the aqueous cooling lubricant can be mixed together on site by dissolving the individual components in water at the desired concentrations.
- aqueous cooling lubricants in the form of an aqueous concentrate which contains the individual active ingredients in the correct proportions, but in concentrated form.
- this concentrate must be diluted with water to the application concentration on site become.
- the concentrate can be one component. ie contain all active ingredients of the cooling lubricant.
- the concentrate can also be sold in the form of two or more separate containers, each of which contains certain components or combinations of components.
- the cooling lubricant can be marketed as a concentrate which contains both about 50 to about 300 g / 1 of polyglycol monoether and or polyglycol diether and also about 50 to about 600 g / 1 of the corrosion inhibitors mentioned and, if appropriate, further active ingredients and auxiliaries .
- separate concentrates of the polyglycol monoethers and / or polyglycol diethers on the one hand and the corrosion inhibitors on the other hand can also be used to prepare or supplement the ready-to-use aqueous cooling lubricant.
- additional active ingredients and auxiliaries to be used optionally are preferably added to the concentrate component which contains the polyglycol monoethers and / or polyglycol diethers.
- the second concentrate then merely represents an aqueous solution of the corrosion inhibitors. This concept has the advantage that the concentrate of the corrosion inhibitors can be used both to supplement the cooling lubricant and to supplement the aqueous cleaning solution.
- the aqueous cleaning solution can also be prepared by dissolving the individual active ingredients in water in the required concentrations on site.
- the preferred procedure is to bring concentrates of the cleaning solution to the market in the same way as to dilute with water on site in the required ratio.
- the concentrate can contain all active and auxiliary substances in the correct relative proportions to each other.
- the same concentrate can then be used which is also used to prepare or to supplement the ready-to-use aqueous cooling lubricant.
- This concept of providing a total of three product concentrates for the cooling lubricant and the cleaning solution increases the flexibility of the subsequent dosing of the individual components and leads to a particularly economical use of materials.
- the cleaning-active substances in the cleaning solution are preferably selected from anionic surfactants, nonionic surfactants, cationic surfactants and from glycol monoethers of the general formula
- R is an alkyl radical having 1 to 5 carbon atoms or a phenyl radical and n is a number in the range from 1 to 5, preferably in the range from 1 to 3.

Description
,MetaIlbearbeitungs- und Reinigungsverfahren' 'Metal processing and cleaning processes'
Die Erfindung liegt auf dem Gebiet der Metallbearbeitung und betrifft die Schritte: spanabhebende Metallbearbeitung und anschließende Reinigung mit Korrosionsschutz. Dabei werden unter „spanabhebender Metallbearbeitung" Bearbeitungsvorgänge verstanden, bei denen die Form eines Metallstücks dadurch verändert wird, daß mit einem Bearbeitungswerkzeug Material von dem zu bearbeitenden Werkstück entfernt wird. Beispiele derartiger spanabhebender Metallbearbeitungsprozesse sind Bohren, Drehen, Fräsen und Schleifen. Für solche Bearbeitungsvorgänge ist es erforderlich, Werkzeug und Werkstück mit einem flüssigen Kühlschmierstoff zu umspülen. Dieser hat die Aufgaben: Schmieren des Werkzeugs, um Nerschweißungen und Überhitzungen zu vermeiden, Abfuhr der entstehenden Wärme und Abtransport der gebildeten Späne oder sonstiger Metallpartikel. Dabei muß der Kühlschmierstoff so beschaffen sein, daß er eine Korrosion des Werkstücks verhindert.The invention is in the field of metalworking and relates to the steps: metal cutting and subsequent cleaning with corrosion protection. Here, "metal cutting" is understood to mean machining operations in which the shape of a piece of metal is changed by removing material from the workpiece to be machined with a machining tool. Examples of such metal machining processes are drilling, turning, milling and grinding. For such machining operations it is necessary to rinse the tool and workpiece with a liquid cooling lubricant, which has the following functions: lubricating the tool to avoid welding and overheating, dissipating the heat generated and removing the chips or other metal particles that are formed. that it prevents corrosion of the workpiece.
In der Technik sind als Kühlschmierstoffe Öle, Öl-in-Wasser-Emulsionen oder wassergelöste Kühlschmierstoffe, die nur aus einer wäßrigen Lösung bestehen, bekannt. In der vorliegenden Erfindung geht es um solche wassergelöste
Schmierstoffe, also Kühlschmierstoffe, die keine wasserunlöslichen Komponenten wie beispielsweise Öle enthalten.In the art, oils, oil-in-water emulsions or water-soluble cooling lubricants which consist only of an aqueous solution are known as cooling lubricants. The present invention is concerned with such water-soluble Lubricants, i.e. cooling lubricants that do not contain water-insoluble components such as oils.
In der Bearbeitungskette eines metallischen Werkstücks wird dieses nach einer spanabhebenden Bearbeitung üblicherweise gereinigt. Hierdurch sollen insbesondere Reste des Kühlschmierstoffs, aber auch sonstiger Schmutz sowie noch anhaftende Metallpartikel entfernt werden. Dabei spielt bisher für den ausgewählten Reiniger die Beschaffenheit des vor dem Reinigungsschritt zur Metallbearbeitung eingesetzten Kühlschmierstoffs nur insofern eine Rolle, als der Reiniger diesen entfernen können muß. Der gesamte Kühlschmierstoff stellt für den Reiniger eine „Schmutzbelastung" dar, die den Reiniger mit der Zeit unbrauchbar macht. Je nach Belastung mit Kühlschmierstoff muß der Reiniger entweder mit neuen reinigungsaktiven Komponenten aufgestockt, durch Badpflege-Maßnahmen regeneriert oder verworfen und neu angesetzt werden. Dies fuhrt zu einem hohen Verbrauch an Reinigerwirkstoffen, die nach Ende der Gebrauchsdauer des Reinigers jeweils entsorgt werden müssen. Dies bringt eine Umweltbelastung mit sich und ist außerdem wegen des erforderlichen Stoffeinsatzes ökonomisch nachteilig.In the processing chain of a metallic workpiece, it is usually cleaned after machining. In this way, in particular residues of the cooling lubricant, but also other dirt and still adhering metal particles are to be removed. So far, the nature of the cooling lubricant used before the cleaning step for metalworking has only played a role for the selected cleaner insofar as the cleaner must be able to remove it. The entire cooling lubricant represents a "dirt load" for the cleaner, which makes the cleaner unusable over time. Depending on the load with cooling lubricant, the cleaner must either be replenished with new cleaning-active components, regenerated by bath care measures or discarded and re-prepared leads to a high consumption of detergent active ingredients, which must be disposed of at the end of the service life of the detergent, which has an environmental impact and is also economically disadvantageous due to the required use of materials.
Die Erfindung stellt sich die Aufgabe, eine Nerfahrenskombination zur spanabhebenden Metallbearbeitung unter Verwendung eines wäßrigen Kühlschmierstoffs und anschließender Reinigung der bearbeiteten Metallteile mit einer wäßrigen Reinigungslösung zur Verfügung zu stellen, bei dem die Inhaltsstoffe des Kühlschmierstoffs und der wäßrigen Reinigungslösung so aufeinander abgestimmt sind, daß Inhaltsstoffe des Kühlschmierstoffs die Reinigerlösung ergänzen oder zumindest nicht negativ beeinflussen. Gemäß diesem Konzept stellt der Kühlschmierstoff für den Reiniger keine „Schmutzbelastung" dar, sondern ergänzt ihn vielmehr. Dies ermöglicht für die Reinigungslösung selbst einen geringeren Einsatz an Wirkstoffen. Die Standzeit der Reinigungslösung wird auch ohne Badpflege-Maßnahmen verlängert. Verringerter Stoffeinsatz und
geringerer Entsorgungsaufwand entlasten die Umwelt und verbilligen das Gesamtverfahren.The invention has for its object to provide a Nerfahrkombination for metal cutting using an aqueous cooling lubricant and subsequent cleaning of the processed metal parts with an aqueous cleaning solution, in which the ingredients of the cooling lubricant and the aqueous cleaning solution are matched so that the ingredients of the Cooling lubricant supplement the cleaning solution or at least not negatively influence it. According to this concept, the cooling lubricant does not represent a "dirt load" for the cleaner, but rather complements it. This enables the cleaning solution itself to use less active ingredients. The service life of the cleaning solution is extended even without bathroom care measures Lower disposal costs relieve the environment and make the entire process cheaper.
Die Erfindung baut dabei auf wäßrigen („wassergelösten") Kühlschmierstoffen auf, die als Schmierkomponente Polyglykol-Monoether und/oder Polyglykol-Diether enthalten. Zusätzlich enthalten wäßrige Kühlschmierstoffe Korrosionsinhibitoren. Weiterhin sind aus der deutschen Patentanmeldung DE 197 23 990.0 Reinigungsmittel für die Metallreinigung bekannt, die als reinigungsaktive Komponenten Glykol-Monoether der allgemeinen FormelThe invention is based on aqueous ("water-soluble") cooling lubricants which contain polyglycol monoether and / or polyglycol diether as the lubricating component. In addition, aqueous cooling lubricants contain corrosion inhibitors. Furthermore, German patent application DE 197 23 990.0 discloses cleaning agents for metal cleaning. the glycol monoethers of the general formula as cleaning-active components
R-O-(CH2-CH(CH3 )-O)n-HRO- (CH 2 -CH (CH 3 ) -O) n -H
enthalten, wobei R einen Alkylrest mit 1 bis 4 C-Atomen oder einen Phenylrest und n eine Zahl im Bereich von 1 bis 5 bedeuten. Diese Glykol-Monoether werden in Kombination mit Kationtensiden im Gewichtsverhältnis Glykol-Monoether zu Kationtensid zwischen 8 : 1 und 100 : 1 eingesetzt. Vorzugsweise enthält dieser Reiniger als weitere Wirkstoffe Korrosionsinhibitoren.contain, where R is an alkyl radical having 1 to 4 carbon atoms or a phenyl radical and n is a number in the range from 1 to 5. These glycol monoethers are used in combination with cationic surfactants in a weight ratio of glycol monoether to cationic surfactant between 8: 1 and 100: 1. This cleaner preferably contains corrosion inhibitors as further active ingredients.
Die erfindungsgemäße Aufgabe wird gelöst durch ein Verfahren zur spanabhebenden Metallbearbeitung unter Verwendung eines wäßrigen Kühlschmierstoffs und anschließender Reinigung der bearbeiteten Metallteile mit einer wäßrigen Reinigungslösung, dadurch gekennzeichnet, daß manThe object of the invention is achieved by a method for metal cutting using an aqueous cooling lubricant and subsequent cleaning of the machined metal parts with an aqueous cleaning solution, characterized in that
a) als Kühlschmierstoff zur spanabhebenden Metallbearbeitung eine wäßrige Lösung einsetzt, die Korrosionsinhibitoren sowie Polyglykol-Monoether und/oder Polyglykol-Diether enthält, unda) uses an aqueous solution as cooling lubricant for metal cutting, which contains corrosion inhibitors and polyglycol monoether and / or polyglycol diether, and
b) als Reinigungslösung eine wäßrige Lösung einsetzt, die reinigungsaktive Stoffe und dieselben Korrosionsinhibitoren wie der Kühlschmierstoff enthält.
Das Wesen der Erfindung besteht demnach zum einen darin, daß der wäßrige (= wassergelöste) Kühlschmierstoff dieselben Korrosionsinhibitoren wie die Reinigungslösung enthält. Wird also Kühlschmierstoff in die Reinigungslösung eingetragen, stellen die Korrosionsinhibitoren des Kühlschmierstoffs für die Reinigungslösung keine Verunreinigung dar. Vielmehr ergänzen sie den Gehalt der Reinigungslösung an Korrosionsinhibitoren. Sie gleichen hierdurch Verluste an Korrosionsinhibitoren aus, die aus der Reinigungslösung mit den gereinigten Werkstücken ausgetragen werden. Daher ist es in verringertem Ausmaß, im Idealfall überhaupt nicht erforderlich, den Gehalt an Korrosionsinhibitoren in der Reinigungslösung zu ergänzen.b) an aqueous solution is used as the cleaning solution which contains cleaning-active substances and the same corrosion inhibitors as the cooling lubricant. The essence of the invention is therefore firstly that the aqueous (= water-soluble) cooling lubricant contains the same corrosion inhibitors as the cleaning solution. If cooling lubricant is therefore introduced into the cleaning solution, the corrosion inhibitors of the cooling lubricant for the cleaning solution do not constitute contamination. Rather, they supplement the content of corrosion inhibitors in the cleaning solution. In this way, they compensate for losses of corrosion inhibitors that are carried out of the cleaning solution with the cleaned workpieces. It is therefore to a lesser extent, ideally not at all, necessary to supplement the corrosion inhibitor content in the cleaning solution.
Zum anderen sind die schmierwirksamen Polyglykol-Monoether bzw. Polyglykol- Diether so ausgewählt, daß sie mit den Komponenten der Reinigungslösung kompatibel sind. Sie bewirken also weder einen Verlust der Reinigungswirkung noch beeinträchtigen sie die Wirksamkeit der Korrosionsinhibitoren der Reinigungslösung. Sie stellen also für die Reinigungslösung keine Verunreinigung dar und machen daher keine Badpflege-Maßnahmen zu ihrer Entfernung erforderlich. Vielmehr stellt sich während des Betriebs in der Reinigungslösung ein stationärer Gehalt an diesen Komponenten ein, da im Gleichgewicht die gleichen Mengen Schmierstoffe in die Reinigungslösung eingeschleppt wie durch die gereinigten Metallteile ausgetragen werden.On the other hand, the lubricating polyglycol monoethers or polyglycol diethers are selected so that they are compatible with the components of the cleaning solution. They therefore do not cause any loss of the cleaning action, nor do they impair the effectiveness of the corrosion inhibitors of the cleaning solution. So they do not represent contamination for the cleaning solution and therefore do not require any bath care measures to remove them. Rather, a steady content of these components occurs in the cleaning solution during operation, since the same amounts of lubricants are carried into the cleaning solution in equilibrium as are discharged through the cleaned metal parts.
Dabei sind die in dem Kühlschmierstoff als Schmierkomponenten einzusetzenden Polyglykol-Monoether bzw. Polyglykol-Diether als solche für diese Verwendung bekannt und im Handel. Dabei werden die Polyglykol-Monoether auch häufig verkürzt, jedoch unkorrekt, als „Polyglykole" bezeichnet. Sie werden dadurch erhalten, daß geeignete Startmoleküle, beispielsweise ein- oder mehrwertige Alkohole mit 1 bis 5 C-Atomen mit Ethylenoxid und/oder Propylenoxid umgesetzt
werden. Hierdurch entsteht eine Polyethylenglykol-, Polypropylenglykol- oder eine gemischte Kette, in der die Alkylenoxideinheiten nach Ringöffnung zu Polyethern verbunden sind. Bei der Bezeichnung „Polyglykole" werden diese Etherbindungen jedoch in der Regel außer acht gelassen. Spricht man von Polyglykolethem, so meint man damit, daß die Polyglykole nicht an jedem Kettenende eine OH-Gruppe tragen, sondern an einem Ende mit einem Alkohol verethert sind. Diese Bezeichnung kann jedoch nicht unterscheiden, ob nur ein Kettenende oder ob beide Kettenenden mit Alkoholen verethert sind. Zur Klarstellung werden im Sinne dieser Erfindung folgende Begriffe gebraucht: Glykol-Monoether bzw. Polyglykol- Monoether stellen oligomere oder polymere Polyalkylenglykolketten dar, die an einem Ende mit einem Alkohol verethert sind. Entsprechend bedeuten die Begriffe Glykol-Diether bzw. Polyglykol-Diether oligomere oder polymere Alkylen- glykolketten, die an beiden Enden mit Alkoholen verethert sind. Dabei ist es nicht erforderlich, daß die Moleküle an beiden Enden dieselben Alkoholgruppen tragen. Der hier gewählte Begriff der Glykol-Diether bzw. Polyglykol-Diether entspricht also der in der Technik auch anzutreffenden Bezeichnung „endgruppen- verschlossene Glykol- bzw. Polyglykolether".The polyglycol monoethers or polyglycol diethers to be used as lubricating components in the cooling lubricant are known as such for this use and are commercially available. The polyglycol monoethers are also frequently shortened, but incorrectly, referred to as “polyglycols”. They are obtained by reacting suitable starting molecules, for example monohydric or polyhydric alcohols having 1 to 5 carbon atoms, with ethylene oxide and / or propylene oxide become. This creates a polyethylene glycol, polypropylene glycol or a mixed chain in which the alkylene oxide units are linked to form polyethers after the ring has been opened. In the term "polyglycols", however, these ether bonds are generally disregarded. When one speaks of polyglycol ethers, one means that the polyglycols do not have an OH group at each chain end, but are etherified with an alcohol at one end. However, this designation cannot differentiate whether only one chain end or whether both chain ends are etherified with alcohols.For the purposes of this invention, the following terms are used for clarification: glycol monoethers or polyglycol monoethers are oligomeric or polymeric polyalkylene glycol chains which are at one end Accordingly, the terms glycol diether or polyglycol diether mean oligomeric or polymeric alkylene glycol chains which are etherified with alcohols at both ends, and it is not necessary for the molecules to carry the same alcohol groups at both ends. The term "glycol diether" or "polyglycol diether" chosen here corresponds to This means that the term "end group-closed glycol or polyglycol ether" can also be found in technology.
Der erfindungsgemäß einzusetzende wäßrige Kühlschmierstoff enthält vorzugsweise solche Polyglykol-Monoether und/oder Polyglykol-Diether, die durch Ethoxylierung und/oder Propoxylierung von ein- oder mehrwertigen Alkoholen mit 1 bis 5 C-Atomen erhältlich sind. Im Falle der Diether sind die Polyalkylenglykolketten am anderen Ende mit Alkoholen mit 1 - 6 C-Atomen verschlossen. Die Polyglykol-Monoether oder -Diether weisen vorzugsweise eine mittlere Molmasse im Bereich von 500 bis 25000 auf.The aqueous cooling lubricant to be used according to the invention preferably contains those polyglycol monoethers and / or polyglycol diethers which can be obtained by ethoxylation and / or propoxylation of mono- or polyhydric alcohols having 1 to 5 carbon atoms. In the case of the Diether, the polyalkylene glycol chains are closed at the other end with alcohols with 1 to 6 carbon atoms. The polyglycol monoethers or diethers preferably have an average molecular weight in the range from 500 to 25,000.
Die Korrosionsinhibitoren, die erfindungsgemäß sowohl im wäßrigen Kühlschmierstoff als auch in der wäßrigen Reinigungslösung eingesetzt werden, sind vorzugsweise ausgewählt aus Alkanolaminen und/oder aus Salzen von
verzweigten oder unverzweigten, gesättigten oder ungesättigten aliphatischen Mono- oder Dicarbonsäuren mit 6 bis 10 C-Atomen und/oder aus aromatischen Carbonsäuren mit 7 bis 10 C-Atomen. Wenn hierbei von Alkanolaminen und von Salzen von Carbonsäuren die Rede ist, so kann dies zum einen bedeuten, daß die Alkanolaminsalze der Carbonsäuren direkt eingesetzt werden. Hiermit äquivalent ist eine Mischung von Alkanolaminen und Carbonsäuren, die miteinander unter Salzbildung reagieren. Weiterhin können die Alkanolamine als solche, die Carbonsäuren als Alkalimetallsalze eingesetzt werden. Äquivalent mit Alkalimetallsalzen von Carbonsäuren sind Mischungen aus Carbonsäuren und Alkalimetallhydroxiden. Je nach pH-Wert in dem gebrauchsfertigen wäßrigen Kühlschmierstoff oder in der wäßrigen Reinigungslösung werden die Alkanolamine und/oder die Carbonsäuren als Gleichgewichtsmischung aus den Neutralmolekülen und den Kationen im Falle der Alkanolamine bzw. der Anionen im Falle der Carbonsäuren vorliegen.The corrosion inhibitors which are used according to the invention both in the aqueous cooling lubricant and in the aqueous cleaning solution are preferably selected from alkanolamines and / or from salts of branched or unbranched, saturated or unsaturated aliphatic mono- or dicarboxylic acids with 6 to 10 carbon atoms and / or from aromatic carboxylic acids with 7 to 10 carbon atoms. If this refers to alkanolamines and salts of carboxylic acids, this can mean, on the one hand, that the alkanolamine salts of the carboxylic acids are used directly. This is equivalent to a mixture of alkanolamines and carboxylic acids that react with one another to form salts. Furthermore, the alkanolamines can be used as such, the carboxylic acids as alkali metal salts. Mixtures of carboxylic acids and alkali metal hydroxides are equivalent to alkali metal salts of carboxylic acids. Depending on the pH in the ready-to-use aqueous cooling lubricant or in the aqueous cleaning solution, the alkanolamines and / or the carboxylic acids will be present as an equilibrium mixture of the neutral molecules and the cations in the case of the alkanolamines or the anions in the case of the carboxylic acids.
Vorzugsweise enthält der anwendungsfertige wäßrige Kühlschmierstoff 2 bis 15 g/1 Polyglykol-Monoether und/oder Polyglykol-Diether und 8 bis 40 g/1 Korrosionsinhibitoren. Als weitere Komponenten kann der wäßrige Kühlschmierstoff zusätzlich Emulgatoren, Puffersubstanzen, Tenside und/oder Biozide enthalten. Sein pH- Wert liegt vorzugsweise im Bereich zwischen etwa 6 und etwa 9,5.The ready-to-use aqueous cooling lubricant preferably contains 2 to 15 g / 1 polyglycol monoether and / or polyglycol diether and 8 to 40 g / 1 corrosion inhibitors. The aqueous cooling lubricant can additionally contain emulsifiers, buffer substances, surfactants and / or biocides as further components. Its pH is preferably in the range between about 6 and about 9.5.
Für den Einsatz bei der spanabhebenden Metallbearbeitung kann der wäßrige Kühlschmierstoff im Prinzip vor Ort dadurch zusammengemischt werden, daß man die einzelnen Komponenten in den erwünschten Konzentrationen in Wasser auflöst. Technisch üblich ist es jedoch, wäßrige Kühlschmierstoffe in Form eines wäßrigen Konzentrats in den Handel zu bringen, das die einzelnen Wirkstoffe im richtigen Mengenverhältnis, jedoch in konzentrierter Form enthält. Für die Anwendung muß dieses Konzentrat vor Ort mit Wasser auf die Anwendungskonzentration verdünnt
werden. Dabei kann das Konzentrat einkomponentig sein. d.h. alle Wirkstoffe des Kühlschmierstoffs enthalten. Das Konzentrat kann jedoch auch in Form zweier oder mehrerer getrennter Gebinde in den Handel kommen, die jeweils bestimmte Komponenten bzw. Kombinationen von Komponenten enthalten. Dies erlaubt es, während des Einsatzes des Kühlschmierstoffs die einzelnen Komponenten getrennt voneinander nachzudosieren, falls diese in unterschiedlichen Verhältnissen verbraucht oder ausgetragen werden. Beispielsweise kann der Kühlschmierstoff als Konzentrat in den Handel kommen, das sowohl etwa 50 bis etwa 300 g/1 Polyglykol-Monoether und oder Polyglykol-Diether als auch etwa 50 bis etwa 600 g/1 der genannten Korrosionsinhibitoren sowie gegebenenfalls weitere Wirk- und Hilfsstoffe enthält. Zum Ansetzen oder zum Ergänzen des anwendungsfertigen wäßrigen Kühlschmierstoffs können jedoch auch getrennte Konzentrate der Polyglykol-Monoether und/oder Polyglykol-Diether einerseits und der Korrosionsinhibitoren andererseits eingesetzt werden. In diesem Falle setzt man fakultativ mitzuverwendende weitere Wirk- und Hilfsstoffe wie beispielsweise Emulgatoren, Puffersubstanzen, Tenside und/oder Biozide vorzugsweise derjenigen Konzentratkomponente zu, die die Polyglykol-Monoether und/oder Polyglykol- Diether enthält. Das zweite Konzentrat stellt dann lediglich eine wäßrige Lösung der Korrosionsinhibitoren dar. Dieses Konzept hat den Vorteil, daß das Konzentrat der Korrosionsinhibitoren sowohl zur Ergänzung des Kühlschmierstoffs als auch zur Ergänzung der wäßrigen Reinigungslösung eingesetzt werden kann.In principle, for use in metal cutting, the aqueous cooling lubricant can be mixed together on site by dissolving the individual components in water at the desired concentrations. However, it is technically customary to market aqueous cooling lubricants in the form of an aqueous concentrate which contains the individual active ingredients in the correct proportions, but in concentrated form. For use, this concentrate must be diluted with water to the application concentration on site become. The concentrate can be one component. ie contain all active ingredients of the cooling lubricant. However, the concentrate can also be sold in the form of two or more separate containers, each of which contains certain components or combinations of components. This allows the individual components to be replenished separately from one another when the cooling lubricant is in use, if these are used up or discharged in different ratios. For example, the cooling lubricant can be marketed as a concentrate which contains both about 50 to about 300 g / 1 of polyglycol monoether and or polyglycol diether and also about 50 to about 600 g / 1 of the corrosion inhibitors mentioned and, if appropriate, further active ingredients and auxiliaries . However, separate concentrates of the polyglycol monoethers and / or polyglycol diethers on the one hand and the corrosion inhibitors on the other hand can also be used to prepare or supplement the ready-to-use aqueous cooling lubricant. In this case, additional active ingredients and auxiliaries to be used optionally, such as emulsifiers, buffer substances, surfactants and / or biocides, are preferably added to the concentrate component which contains the polyglycol monoethers and / or polyglycol diethers. The second concentrate then merely represents an aqueous solution of the corrosion inhibitors. This concept has the advantage that the concentrate of the corrosion inhibitors can be used both to supplement the cooling lubricant and to supplement the aqueous cleaning solution.
Auch die wäßrige Reinigungslösung kann man prinzipiell so zubereiten, daß man die einzelnen Wirkstoffe vor Ort in Wasser in den erforderlichen Konzentrationen auflöst. Wie bei der Kühlschmierstofflösung geht man jedoch auch hier vorzugsweise so vor, daß man Konzentrate der Reinigungslösung in den Handel bringt, wie man vor Ort mit Wasser im erforderlichen Verhältnis verdünnt. Dabei kann das Konzentrat alle Wirk- und Hilfsstoffe im richtigen relativen Mengenverhältnis zueinander enthalten. Im Sinne des erfindungsgemäßen
Verfahrenskonzeptes ist es jedoch vorzuziehen, ein Konzentrat der wäßrigen Reinigungslösung zur Verfügung zu stellen, das die reinigungsaktiven Komponenten und sonstige fakultative Wirk- und Hilfsstoffe, nicht jedoch die Korrosionsinhibitoren enthält. Zur Einstellung des Gehalts an Korrosionsinhibitoren in der anwendungsfertigen wäßrigen Reinigungslösung kann dann dasselbe Konzentrat verwendet werden, das auch zum Ansetzen bzw. zum Ergänzen des anwendungsfertigen wäßrigen Kühlschmierstoffs dient. Dieses Konzept, insgesamt drei Produktkonzentrate für den Kühlschmierstoff und die Reinigungslösung zusammen zur Verfügung zu stellen, erhöht die Flexibilität der Nachdosierung der einzelnen Komponenten und führt zu einem besonders wirtschaftlichen Stoffeinsatz.In principle, the aqueous cleaning solution can also be prepared by dissolving the individual active ingredients in water in the required concentrations on site. As with the cooling lubricant solution, however, the preferred procedure is to bring concentrates of the cleaning solution to the market in the same way as to dilute with water on site in the required ratio. The concentrate can contain all active and auxiliary substances in the correct relative proportions to each other. In the sense of the invention However, it is preferable to provide a concentrate of the aqueous cleaning solution which contains the cleaning-active components and other optional active ingredients and auxiliaries, but not the corrosion inhibitors. To adjust the content of corrosion inhibitors in the ready-to-use aqueous cleaning solution, the same concentrate can then be used which is also used to prepare or to supplement the ready-to-use aqueous cooling lubricant. This concept of providing a total of three product concentrates for the cooling lubricant and the cleaning solution increases the flexibility of the subsequent dosing of the individual components and leads to a particularly economical use of materials.

3,00 g Monoethanolamin 11,00 g Triethanolamin3.00 g monoethanolamine 11.00 g triethanolamine
5,28 g Sebacinsäure5.28 g sebacic acid
7,50 g Polyethylen-/propylen-glykolether (Startmolekül: Pentaerythrit), Molmasse 15.0007.50 g of polyethylene / propylene glycol ether (starting molecule: pentaerythritol), molecular weight 15,000
2,85 g 6-(((4-Methylphenyl)-sulfonyl)-amino)-hexansäure2.85 g of 6 - (((4-methylphenyl) sulfonyl) amino) hexanoic acid
4,20 g Glycerin4.20 g glycerin
0,12 g Benzotriazol, 1H,2,3- Rest zu 1000 ml: mit Wasser aufgefüllt
Dieser kann durch geeignetes Verdünnen eines wäßrigen Konzentrats erhalten werden, das etwa 50 bis etwa 300 g/1 Polyglykol-Monoether und/oder Polyglykol- Diether und etwa 50 bis etwa 600 g/1 Korrosionsinhibitoren enthält.0.12 g benzotriazole, 1H, 2,3-residue to 1000 ml: made up with water This can be obtained by suitably diluting an aqueous concentrate which contains about 50 to about 300 g / 1 polyglycol monoether and / or polyglycol diether and about 50 to about 600 g / 1 corrosion inhibitors.
Eine im Rahmen des erfindungsgemäßen Verfahrens einsetzbare wäßrige Reinigerlösung kann beispielsweise folgende Zusammensetzung aufweisen:An aqueous cleaning solution which can be used in the process according to the invention can have, for example, the following composition:
Beispiel für den Reiniger (Beispiel 3) 0,60 g Monoethanolamin 2,70 g Triethanolamin 1,79 g SebacinsäureExample for the cleaner (example 3) 0.60 g monoethanolamine 2.70 g triethanolamine 1.79 g sebacic acid
0,27 g Tripropylenglykolmonomethylether 0,01 g 2-Hydroxidodecyl-dimethyl-benzyl-ammonium-benzoat Rest zu 1000 ml: mit Wasser aufgefüllt0.27 g tripropylene glycol monomethyl ether 0.01 g 2-hydroxidodecyl-dimethyl-benzyl-ammonium-benzoate Rest of 1000 ml: made up with water
Auch die Reinigerlösung wird vorzugsweise vor Ort durch Verdünnen eines Konzentrats mit Wasser zubereitet. Der Verdünnungsfaktor des Konzentrats liegt vorzugsweise im Bereich von etwa 1 : 200 bis etwa 1 : 20. Zum Neuansatz eines Reinigerbades kann ein Konzentrat eingesetzt werden, das alle Komponenten der Reinigerlösung im entsprechenden Gewichtsverhältnis enthält. Zur Ergänzung der Reinigungslösung mit reinigungsaktiven Wirkstoffen empfiehlt sich jedoch der Einsatz eines Konzentrats, das weniger oder keine Korrosionsinhibitoren enthält, da diese durch den Kühlschmierstoff in die Reinigungslösung eingetragen und hierdurch ergänzt werden.The cleaning solution is also preferably prepared on site by diluting a concentrate with water. The dilution factor of the concentrate is preferably in the range from about 1: 200 to about 1: 20. A concentrate containing all components of the detergent solution in the appropriate weight ratio can be used to prepare a detergent bath. To supplement the cleaning solution with active cleaning agents, however, the use of a concentrate that contains fewer or no corrosion inhibitors is recommended, since these are introduced into the cleaning solution by the cooling lubricant and thereby supplemented.
Die Reinigungs Wirkung von unbelastetem sowie mit Kühlschmierstoff belastetem Reiniger wird in folgendem Test ermittelt:
Stahlbleche der Qualität St 1405 werden mit Tensidlösung manuell vorgereinigt und mit einem Testschmutz, bestehend aus Ruß, Graphit, Fettsäuretriglycerid und Kohlenwasserstoffraktionen, beschmutzt. Nach 30 Minuten Lagerung im Wärmeschrank bei 60° C werden sie mit Reinigerlösung in einer Laborspritzanlage bei 60° C 2 min bei 3 bar bespritzt. Zur Simulation zusätzlich eingetragener Fremdöle wurde die Reinigerlösung zuvor mit 10 g/1 Gerolub^ 3005/7 (eingetragenes Warenzeichen der Fa. Henkel KGaA, Düsseldorf), einer metastabilen O/W-Emulsion, versetzt. Nach Abspülen mit Wasser wird die Restverschmutzung durch Oxidation des auf der Oberfläche verbliebenen Kohlenstoffs quantitativ bestimmt.The cleaning effect of unloaded and coolant-loaded cleaners is determined in the following test: Steel sheets of quality St 1405 are manually pre-cleaned with surfactant solution and soiled with a test dirt consisting of soot, graphite, fatty acid triglyceride and hydrocarbon fractions. After 30 minutes of storage in an oven at 60 ° C, they are sprayed with cleaning solution in a laboratory spraying system at 60 ° C for 2 min at 3 bar. To simulate additional foreign oils, 10 g / 1 Gerolub ^ 3005/7 (registered trademark of Henkel KGaA, Düsseldorf), a metastable O / W emulsion, was added to the cleaning solution. After rinsing with water, the residual contamination is quantified by oxidation of the carbon remaining on the surface.
Die Reinigungsleistung („Reinigungseffizienz") ist der Quotient aus der abgereinigten Verschmutzung zur Verschmutzung vor dem Reinigungsversuch, ebenfalls gemessen durch Oxidation des Kohlenstoffs auf der Oberfläche, zur Darstellung als %-Wert mit 100 multipliziert.The cleaning performance ("cleaning efficiency") is the quotient from the cleaned contamination to the contamination before the cleaning attempt, likewise measured by oxidation of the carbon on the surface, multiplied by 100 for representation as a% value.
