Definitions
- the invention is in the field of metalworking and relates to the Steps: metal cutting and subsequent cleaning and / or anti-corrosion treatment.
- metal cutting machining understood machining operations, at which the shape of a piece of metal is changed by using a Machining tool Material from the workpiece to be machined Will get removed.
- cutting Metalworking processes are drilling, turning, milling and grinding.
- tools and Rinse the workpiece with a liquid coolant This one has the Tasks: lubricate the tool to weld and To avoid overheating, dissipation of the heat and Removal of the chips or other metal particles formed. It must the cooling lubricant should be such that it corrodes the Workpiece prevented.
- the present invention is concerned with oil-in-water emulsions and their water-miscible concentrates, i.e. cooling lubricants, the one Oil component included.
- the object of the invention is to provide a combination of means and methods metal cutting using a water mixed Cooling lubricant and subsequent cleaning and / or corrosion protection of the processed metal parts with an aqueous cleaning / corrosion protection agent to provide, in which the ingredients of the cooling lubricant and the aqueous cleaning / corrosion protection agents are so coordinated that the coolant contains the cleaning / corrosion protection agent complement or at least not negatively influence.
- the cooling lubricant does not provide for the cleaning / corrosion protection agent "Dirt pollution", but rather complements it. This allows for that Cleaning / corrosion protection agents even a lower use Agents.
- the service life of the cleaning / corrosion protection agent is also extended without bathroom care measures. Reduced use of fabric and less Disposal efforts relieve the environment and make the entire process cheaper.
- the invention relates to a combination of agents according to claims 1 and 4, respectively.
- Emulsifier system to be used according to the invention is from the German one Patent application DE-A-197 03 083 known. Compared to conventional ones Emulsifier systems have the advantage that they are soft to medium hard Water, i.e. in water with less than 12 ° and in particular with less than 8 ° dH tends to foam little.
- composition of the emulsifier system and the molecular structure of the emulsifiers used must therefore meet stringent requirements.
- fatty alcohol ethoxylates / propoxylates must be present which carry both 2 to 6 ethylene oxide units and 4 to 8 propylene oxide units.
- These more hydrophilic components are to be combined with the more hydrophobic components
- the approximate weight ratio is to be observed. Distillation residues of fatty alcohols with 12 to 24 carbon atoms are available from Henkel KGaA, Düsseldorf, under the name Pernil R RU.
- Non-polar or polar oils can be used as the oil component in the first agent petrochemical or native origin.
- suitable synthetic oil components are paraffinic or naphthenic mineral oil, dialkyl ethers with 12 to 20 carbon atoms and esterotes.
- the ester oils can be of vegetable or animal origin be and as an ester of glycerol with 3 fatty acids (so-called Fatty acid triglycerides).
- An example of such an ester oil is rapeseed oil.
- Ester oils can also be obtained synthetically by using glycerol with selected fatty acids esterified or that you can use natural fats and oils other fatty acids transesterified.
- the corrosion inhibitors according to the invention both in aqueous Cooling lubricant as well as in the aqueous cleaning / corrosion protection agent as well as used in their concentrates are preferably selected from alkanolamines and / or from 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, the Some or all of the carboxylic acids are present as salts. If here of alkanolamines and salts of carboxylic acids, so can on the one hand, this means that the alkanolamine salts of the carboxylic acids can be used directly.
- the first agent (the cooling lubricant or its concentrate) and the second agent (the cleaning / anti-corrosion agent or its Concentrate) contain the same corrosion inhibitors. However, this is not mandatory. It is only necessary to ensure that both that first means and the second means one or more of each contain the aforementioned corrosion inhibitors. It is preferable however, that the first agent is one or more corrosion inhibitors contains, which are also present in the second means.
- the two remedies in a ready-to-use form during ongoing operation Carrying cooling lubricant residues into the cleaning / corrosion protection agent in the latter automatically one over time Combination of a corrosion inhibitor, which is also the first agent is available.
- the first can be used for metal cutting Agent, the water-mixed coolant, in principle on site be mixed together that the individual components in the desired concentrations in water or emulsified.
- water-miscible cooling lubricants in the form of a Bring concentrate in the trade, the individual active ingredients in the correct proportion, but in a concentrated form.
- This concentrate must be applied to the site with water Application concentration can be diluted.
- the aqueous cleaning / corrosion protection agent can also be used Prepare so that the individual active ingredients in water in the dissolve or suspend required concentrations.
- cooling lubricant is also preferably carried out here in such a way that Brings concentrates of the cleaning / corrosion protection agent to the market, which are diluted on site with water in the required ratio.
- both the first can in the combination of agents according to the invention Agent as well as the second agent are present as a water-miscible concentrate. contains.
- the second agent contains 10 to 40% by weight Emulsifier system and 20 to 40 wt .-% corrosion inhibitors. Both means can optionally contain additional water and / or other active substances and auxiliary substances, the proportions are of course to be chosen so that the Sum of the components is 100% by weight.
- the first agent can contain further active ingredients and auxiliaries: General lubrication additives and in particular so-called “extreme pressure" additives (EP additives), other corrosion inhibitors such as boric acid or alkylphosphonic acids and additional alkanolamines and solubilizers such as for example glycols, glycerin or sodium cumene sulfonate.
- EP additives extreme pressure additives
- other corrosion inhibitors such as boric acid or alkylphosphonic acids and additional alkanolamines and solubilizers such as for example glycols, glycerin or sodium cumene sulfonate.
- Special non-ferrous metal corrosion inhibitors can also be used to process non-ferrous metals be used. Examples include benzotriazole, Tolyltriazole, thiazoles or salts of pyridine thiol N-oxide.
- Can continue Biocides are added which extend the life of the concentrate Mix ready to use with water prepared Extend cooling lubricant emul
- the first agent can be made exclusively from the oil component, the Emulsifier system and the corrosion inhibitors exist. the preparation, however, it usually contains small amounts of water, for example in the range from about 2 to about 10% by weight. These can either be used Raw materials in the agent, for example if you consider corrosion inhibitors Carboxylic acids are used, which are neutralized with aqueous potassium hydroxide solution. additionally can optionally the above-mentioned further active ingredients and auxiliaries to be present.
- the second agent necessarily contains at least as a concentrate 20% by weight of water and / or further active ingredients and auxiliaries. In the simplest case it contains 20 to 20 in addition to the emulsifier system and the corrosion inhibitors 70% by weight of water and no other active ingredients.
- the second agent can be in the form of both its concentrate and its ready-to-use water-diluted preparation form Contain builder substances, biocides and / or complexing agents.
- builder substances are alkali metal orthophosphates, polyphosphates, -silicates, -borates, -carbonates, -poly-acrylates and -gluconates.
- This Builders sometimes have complex properties and have a water softening effect. Instead of or in addition to this can stronger complexing agents such as 1-hydroxyethane-1,1-diphosphonic acid or 2-phosphonobutane-1,2,4-tricarboxylic acid become.
- complexing agents such as 1-hydroxyethane-1,1-diphosphonic acid or 2-phosphonobutane-1,2,4-tricarboxylic acid become.
- ethylenediaminetetraacetates or nitrilotriacetates into consideration.
- the invention further relates to the combination of agents in a ready-to-use form, the cooling lubricant (the first agent) and the aqueous cleaning / corrosion protection agent (the second agent) as a water-diluted emulsion, Suspension or solution.
- the form of application of the first agent is always an oil-in-water emulsion.
- the emulsifier system to be used according to the invention leads to the technical advantage that the ready-to-use aqueous preparations of The first and the second means little in soft water Tend to foam.
- the concentrates on the Application concentration can therefore not only hard water, but also medium hard water (less than 12 ° dH) or even soft water (less than 8 ° dH) can be used. Even water with a hardness of less than 4 ° dH can be used, sometimes even demineralized water, without the Use of the agent foam problems occur.
- the invention A combination of agents can therefore also be used in the spray process in the temperature range between the freezing point and the boiling point of the ready-to-use Preparations are used. A minimum temperature for In contrast to conventional neutral cleaners, spray applications do not have to be respected.
- the invention Medium combination can also be used in hard water without disadvantages.
- the second agent is preferably used as a cleaning solution as a so-called Neutral cleaner formulated.
- the usual pH of this so-called Ready to use neutral cleaner is in the range of about 6.5 to about 9.
- the cooling lubricant is used preferably an oil-in-water emulsion, which is obtainable by that a concentrate of the first agent as in claim 1, the possible composition is explained in more detail above, in Weight ratio between about 0.5: about 99.5 to about 10: about 90 with Water mixed.
- an aqueous solution or suspension is available that a concentrate of the second agent, as in claim 1 and explained in more detail in the above description, in Weight ratio between about 0.5: about 99.5 to about 10: about 90 with Water mixed. As explained above, this can also be done in each case medium hard or even soft water can be used without the application of the process according to the invention foam problems occur.

Abstract
Description
Die Erfindung liegt auf dem Gebiet der Metallbearbeitung und betrifft die Schritte: spanabhebende Metallbearbeitung und anschließende Reinigung und/oder Korrosionsschutzbehandlung. 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 Verschweißungen 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 and / or anti-corrosion treatment. Here are under "metal cutting machining" understood machining operations, at which the shape of a piece of metal is changed by using a Machining tool Material from the workpiece to be machined Will get removed. Examples of such cutting Metalworking processes are drilling, turning, milling and grinding. For such machining operations it is necessary to use tools and Rinse the workpiece with a liquid coolant. This one has the Tasks: lubricate the tool to weld and To avoid overheating, dissipation of the heat and Removal of the chips or other metal particles formed. It must the cooling lubricant should be such that it corrodes the Workpiece prevented.
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 Öl-in-Wasser-Emulsionen und deren wassermischbare Konzentrate, also Kühlschmierstoffe, die eine Ölkomponente enthalten. In technology, oils, oil-in-water emulsions or are used as cooling lubricants water-soluble cooling lubricants that only consist of an aqueous solution, known. The present invention is concerned with oil-in-water emulsions and their water-miscible concentrates, i.e. cooling lubricants, the one Oil component included.
In der Bearbeitungskette eines metallischen Werkstücks wird dieses nach einer spanabhebenden Bearbeitung üblicherweise gereinigt und/oder gegen Korrosion geschützt. Durch die Reinigung 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 führt 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, this is after a Machining usually cleaned and / or against corrosion protected. The cleaning should remove residues of the cooling lubricant, but also other dirt as well as adhering metal particles are removed become. So far, the nature of the before the cleaning step for metalworking coolant used only in so far 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 The cleaner must use cooling lubricant either with new active cleaning agents Components added, regenerated through bathroom care measures or discarded and re-scheduled. This leads to high consumption Detergent ingredients, each after the end of the cleaner life must be disposed of. This entails and is an environmental burden also economically disadvantageous because of the required use of materials.
Die Erfindung stellt sich die Aufgabe, eine Mittel- und Verfahrenskombination zur spanabhebenden Metallbearbeitung unter Verwendung eines wassergemischten Kühlschmierstoffs und anschließender Reinigung und/oder Korrosionsschutz der bearbeiteten Metallteile mit einem wäßrigen Reinigungs-/Korrosionsschutzmittel zur Verfügung zu stellen, bei dem die Inhaltsstoffe des Kühlschmierstoffs und des wäßrigen Reinigungs-/Korrosionsschutzmittels so aufeinander abgestimmt sind, daß Inhaltsstoffe des Kühlschmierstoffs das Reinigungs-/Korrosionsschutzmittel ergänzen oder zumindest nicht negativ beeinflussen. Gemäß diesem Konzept stellt der Kühlschmierstoff für das Reinigungs-/Korrosionsschutzmittel keine "Schmutzbelastung" dar, sondern ergänzt es vielmehr. Dies ermöglicht für das Reinigungs-/Korrosionsschutzmittel selbst einen geringeren Einsatz an Wirkstoffen. Die Standzeit des Reinigungs-/Korrosionsschutzmittels wird auch ohne Badpflege-Maßnahmen verlängert. Verringerter Stoffeinsatz und geringerer Entsorgungsaufwand entlasten die Umwelt und verbilligen das Gesamtverfahren. The object of the invention is to provide a combination of means and methods metal cutting using a water mixed Cooling lubricant and subsequent cleaning and / or corrosion protection of the processed metal parts with an aqueous cleaning / corrosion protection agent to provide, in which the ingredients of the cooling lubricant and the aqueous cleaning / corrosion protection agents are so coordinated that the coolant contains the cleaning / corrosion protection agent complement or at least not negatively influence. According to this concept the cooling lubricant does not provide for the cleaning / corrosion protection agent "Dirt pollution", but rather complements it. This allows for that Cleaning / corrosion protection agents even a lower use Agents. The service life of the cleaning / corrosion protection agent is also extended without bathroom care measures. Reduced use of fabric and less Disposal efforts relieve the environment and make the entire process cheaper.
In einem ersten Aspekt betrifft die Erfindung eine Mittelkombination gemäß Anspruch 1 bzw. 4.In a first aspect, the invention relates to a combination of agents according to claims 1 and 4, respectively.
Das erfindungsgemäß einzusetzende Emulgatorsystem ist aus der deutschen Patentanmeldung DE-A-197 03 083 bekannt. Gegenüber herkömmlichen Emulgatorsystemen hat es den Vorteil, daß es in weichem bis mittelhartem Wasser, also in Wasser mit weniger als 12° und insbesondere mit weniger als 8° dH nur wenig zur Schaumbildung neigt.The emulsifier system to be used according to the invention is from the German one Patent application DE-A-197 03 083 known. Compared to conventional ones Emulsifier systems have the advantage that they are soft to medium hard Water, i.e. in water with less than 12 ° and in particular with less than 8 ° dH tends to foam little.
An die Zusammensetzung des Emulgatorsystems und die molekulare Struktur der verwendeten Emulgatoren sind also enge Anforderungen zu stellen. Zum einen müssen gemäß a) Fettalkoholethoxylate/Propoxylate vorhanden sein, die sowohl 2 bis 6 Ethylenoxideinheiten als auch 4 bis 8 Propylenoxideinheiten tragen. Diese hydrophileren Komponenten sind zu kombinieren mit den hydrophoberen Komponenten b) unalkoxylierte Fettalkohole mit 12 bis 24 C-Atomen, deren Destillationsrückstand oder deren Alkoxylierungsprodukte mit bis zu im Mittel höchstens 3 Propylenoxideinheiten. Weiterhin ist das angegebene ungefähre Gewichtsverhältnis zu beachten. Destillationsrückstand von Fettalkoholen mit 12 bis 24 C-Atomen ist von der Henkel KGaA, Düsseldorf, unter der Bezeichnung PernilR RU erhältlich.The composition of the emulsifier system and the molecular structure of the emulsifiers used must therefore meet stringent requirements. Firstly, according to a), fatty alcohol ethoxylates / propoxylates must be present which carry both 2 to 6 ethylene oxide units and 4 to 8 propylene oxide units. These more hydrophilic components are to be combined with the more hydrophobic components b) unalkoxylated fatty alcohols with 12 to 24 carbon atoms, their distillation residue or their alkoxylation products with up to a maximum of 3 propylene oxide units on average. Furthermore, the approximate weight ratio is to be observed. Distillation residues of fatty alcohols with 12 to 24 carbon atoms are available from Henkel KGaA, Düsseldorf, under the name Pernil R RU.
Als Ölkomponente im ersten Mittel können unpolare oder polare Öle petrochemischen oder nativen Ursprungs eingesetzt werden. Weiterhin sind synthetische Ölkomponenten geeignet. Beispiele einsetzbarer Ölkomponenten sind paraffinisches oder naphthenisches Mineralöl, Dialkylether mit 12 bis 20 C-Atomen und Esteröte. Die Esteröle können pflanzlichen oder tierischen Ursprungs sein und als Ester von Glycerin mit 3 Fettsäuren vorliegen (sogenannte Fettsäuretriglyceride). Ein Beispiel eines derartigen Esteröls ist Rüböl. Solche Esteröle können auch synthetisch dadurch erhalten werden, daß man Glycerin mit ausgewählten Fettsäuren verestert oder daß man natürliche Fette und Öle mit anderen Fettsäuren umestert.Non-polar or polar oils can be used as the oil component in the first agent petrochemical or native origin. Furthermore are suitable synthetic oil components. Examples of usable oil components are paraffinic or naphthenic mineral oil, dialkyl ethers with 12 to 20 carbon atoms and esterotes. The ester oils can be of vegetable or animal origin be and as an ester of glycerol with 3 fatty acids (so-called Fatty acid triglycerides). An example of such an ester oil is rapeseed oil. Such Ester oils can also be obtained synthetically by using glycerol with selected fatty acids esterified or that you can use natural fats and oils other fatty acids transesterified.
Die Korrosionsinhibitoren, die erfindungsgemäß sowohl im wäßrigen Kühlschmierstoff als auch in dem wäßrigen Reinigungs-/Korrosionsschutzmittel sowie jeweils in deren Konzentraten eingesetzt werden, sind vorzugsweise ausgewählt aus Alkanolaminen und/oder aus 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, wobei die Carbonsäuren teilweise oder vollständig als Salze vorliegen. 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, vorzugsweise als Kaliumsalze eingesetzt werden. Äquivalent mit Alkalimetallsalzen von Carbonsäuren sind Mischungen aus Carbonsäuren und Alkalimetallhydroxiden. Je nach pH-Wert in dem gebrauchsfertigen wassergemischten Kühlschmierstoff oder in dem wäßrigen Reinigungs-/Korrosionsschutzmittel 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 according to the invention both in aqueous Cooling lubricant as well as in the aqueous cleaning / corrosion protection agent as well as used in their concentrates are preferably selected from alkanolamines and / or from 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, the Some or all of the carboxylic acids are present as salts. If here of alkanolamines and salts of carboxylic acids, so can on the one hand, this means that the alkanolamine salts of the carboxylic acids can be used directly. This is equivalent to a mixture of Alkanolamines and carboxylic acids that work together to form salts react. Furthermore, the alkanolamines as such, the carboxylic acids as alkali metal salts, preferably as potassium salts. Mixtures of are equivalent to alkali metal salts of carboxylic acids Carboxylic acids and alkali metal hydroxides. Depending on the pH in the ready-to-use water-mixed cooling lubricant or in the Alkanolamines become aqueous cleaning / corrosion protection agents and / or the carboxylic acids as an equilibrium mixture of the Neutral molecules and the cations in the case of the alkanolamines or the Anions are present in the case of carboxylic acids.
Dabei können das erste Mittel (der Kühlschmierstoff oder sein Konzentrat) und das zweite Mittel (das Reinigungs-/Korrosionsschutzmittel oder dessen Konzentrat) die gleichen Korrosionsinhibitoren enthalten. Dies ist jedoch nicht erforderlich. Es muß lediglich dafür gesorgt werden, daß sowohl das erste Mittel als auch das zweite Mittel jeweils einen oder mehrere der vorstehend genannten Korrosionsinhibitoren enthalten. Vorzuziehen ist es jedoch, daß das erste Mittel einen oder mehrere Korrosionsinhibitoren enthält, die auch im zweiten Mittel vorhanden sind. Liegen die beiden Mittel in anwendungsfertiger Form im laufenden Betrieb vor, stellt sich durch Überschleppen von Kühlschmierstoffresten in das Reinigungs-/Korrosionsschutzmittel in letzterem mit der Zeit automatisch eine Kombination von Korrosionsinhibitoren ein, die auch im ersten Mittel vorhanden ist.The first agent (the cooling lubricant or its concentrate) and the second agent (the cleaning / anti-corrosion agent or its Concentrate) contain the same corrosion inhibitors. However, this is not mandatory. It is only necessary to ensure that both that first means and the second means one or more of each contain the aforementioned corrosion inhibitors. It is preferable however, that the first agent is one or more corrosion inhibitors contains, which are also present in the second means. Are the two remedies in a ready-to-use form during ongoing operation Carrying cooling lubricant residues into the cleaning / corrosion protection agent in the latter automatically one over time Combination of a corrosion inhibitor, which is also the first agent is available.
Für den Einsatz bei der spanabhebenden Metallbearbeitung kann das erste Mittel, der wassergemischte Kühlschmierstoff, im Prinzip vor Ort dadurch zusammengemischt werden, daß man die einzelnen Komponenten in den erwünschten Konzentrationen in Wasser auflöst bzw. emulgiert. Technisch üblich ist es jedoch, wassermischbare Kühlschmierstoffe in Form eines 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.The first can be used for metal cutting Agent, the water-mixed coolant, in principle on site be mixed together that the individual components in the desired concentrations in water or emulsified. Technically However, it is common to use water-miscible cooling lubricants in the form of a Bring concentrate in the trade, the individual active ingredients in the correct proportion, but in a concentrated form. For the This concentrate must be applied to the site with water Application concentration can be diluted.
Auch das wäßrige Reinigungs-/Korrosionsschutzmittel kann man prinzipiell so zubereiten, daß man die einzelnen Wirkstoffe vor Ort in Wasser in den erforderlichen Konzentrationen auflöst bzw. suspendiert. Wie bei dem Kühlschmierstoff geht man jedoch auch hier vorzugsweise so vor, daß man Konzentrate des Reinigungs-/Korrosionsschutzmittels in den Handel bringt, die man vor Ort mit Wasser im erforderlichen Verhältnis verdünnt.In principle, the aqueous cleaning / corrosion protection agent can also be used Prepare so that the individual active ingredients in water in the dissolve or suspend required concentrations. Like that However, cooling lubricant is also preferably carried out here in such a way that Brings concentrates of the cleaning / corrosion protection agent to the market, which are diluted on site with water in the required ratio.
Demgemäß kann in der erfindungsgemäßen Mittelkombination sowohl das erste Mittel als auch das zweite Mittel als wassermischbares Konzentrat vorliegen. enthält.Accordingly, both the first can in the combination of agents according to the invention Agent as well as the second agent are present as a water-miscible concentrate. contains.
Das erste Mittel 10 bis 40 Gew.-% der Ölkomponenten, 10 bis 40 Gew.-% des Emulgatorsystems und 20 bis 40 Gew.-% Korrosionsinhibitoren. Das zweite Mittel enthält 10 bis 40 Gew.-% Emulgatorsystem und 20 bis 40 Gew.-% Korrosionsinhibitoren. Beide Mittel können ggf. zusätzlich Wasser und/oder weitere Wirk- und Hilfsstoffe enthalten, wobei die Mengenverhältnisse selbstverständlich so zu wählen sind, daß die Summe der Komponenten 100 Gew.-% ergibt.The first agent 10 to 40% by weight of the oil components, 10 up to 40% by weight of the emulsifier system and 20 to 40% by weight Corrosion inhibitors. The second agent contains 10 to 40% by weight Emulsifier system and 20 to 40 wt .-% corrosion inhibitors. Both means can optionally contain additional water and / or other active substances and auxiliary substances, the proportions are of course to be chosen so that the Sum of the components is 100% by weight.
Beispielsweise kann das erste Mittel als weitere Wirk- und Hilfsstoffe enthalten: Schmieradditive allgemein und insbesondere sogenannte "Extreme Pressure"-Additive (EP-Additive), weitere Korrosionsinhibitoren wie beispielsweise Borsäure oder Alkylphosphonsäuren sowie zusätzliche Alkanolamine und Lösevermittler wie beispielsweise Glycole, Glycerin oder Natriumcumolsulfonat. Für die Verwendung zur Bearbeitung von Buntmetallen können zusätzlich spezielle Buntmetall-Korrosionsinhibitoren eingesetzt werden. Beispiele hierfür sind Benzotriazol, Tolyltriazol, Thiazole oder Salze des Pyridinthiol-N-Oxids. Weiterhin können Biozide zugesetzt werden, die die Standzeit der aus dem Konzentrat durch Vermischen mit Wasser hergestellten anwendungsfertigen Kühlschmierstoffemulsion verlängern. Bei Bedarf können solche Biozide jedoch der anwendungsfertigen wassergemischten Kühlschmierstoffemulsion direkt zugesetzt werden.For example, the first agent can contain further active ingredients and auxiliaries: General lubrication additives and in particular so-called "extreme pressure" additives (EP additives), other corrosion inhibitors such as boric acid or alkylphosphonic acids and additional alkanolamines and solubilizers such as for example glycols, glycerin or sodium cumene sulfonate. For the use Special non-ferrous metal corrosion inhibitors can also be used to process non-ferrous metals be used. Examples include benzotriazole, Tolyltriazole, thiazoles or salts of pyridine thiol N-oxide. Can continue Biocides are added which extend the life of the concentrate Mix ready to use with water prepared Extend cooling lubricant emulsion. However, if necessary, such biocides the ready-to-use water-mixed cooling lubricant emulsion directly be added.
Das erste Mittel kann ausschließlich aus der Ölkomponente, dem Emulgatorsystem und den Korrosionsinhibitoren bestehen. Herstellungsbedingt enthält es jedoch in der Regel geringe Anteile Wasser, beispielsweise im Bereich von etwa 2 bis etwa 10 Gew.-%. Diese gelangen entweder über die verwendeten Rohstoffe in das Mittel, beispielsweise wenn man als Korrosionsinhibitoren Carbonsäuren einsetzt, die man mit wäßriger Kalilauge neutralisiert. Zusätzlich können fakultativ die vorstehend genannten weiteren Wirk- und Hilfsstoffe anwesend sein. Das zweite Mittel enthält als Konzentrat zwangsläufig mindestens 20 Gew.-% Wasser und/oder weitere Wirk- und Hilfsstoffe. Im einfachsten Falle enthält es außer dem Emulgatorsystem und den Korrosionsinhibitoren noch 20 bis 70 Gew.-% Wasser und keine weiteren Wirk- und Hilfsstoffe.The first agent can be made exclusively from the oil component, the Emulsifier system and the corrosion inhibitors exist. the preparation, however, it usually contains small amounts of water, for example in the range from about 2 to about 10% by weight. These can either be used Raw materials in the agent, for example if you consider corrosion inhibitors Carboxylic acids are used, which are neutralized with aqueous potassium hydroxide solution. additionally can optionally the above-mentioned further active ingredients and auxiliaries to be present. The second agent necessarily contains at least as a concentrate 20% by weight of water and / or further active ingredients and auxiliaries. In the simplest case it contains 20 to 20 in addition to the emulsifier system and the corrosion inhibitors 70% by weight of water and no other active ingredients.
Das zweite Mittel kann sowohl in Form seines Konzentrats als auch seiner anwendungsfertigen wasserverdünnten Zubereitungsform zusätzlich Buildersubstanzen, Biozide und/oder Komplexbildner enthalten. Beispiele von Buildersubstanzen sind Alkalimetallorthophosphate, -polyphosphate, -silikate, -borate, -carbonate, -poly-acrylate und -gluconate. Diese Buildersubstanzen haben teilweise komplexierende Eigenschaften und wirken dadurch wasserenthärtend. Anstelle hiervon oder zusätzlich hierzu können stärkere Komplexbildner wie beispielsweise 1-Hydroxyethan-1,1-Diphosphonsäure oder 2-Phosphonobutan-1,2,4-Tricarbonsäure eingesetzt werden. Weiterhin kommen Ethylendiamintetraacetate oder Nitrilotriacetate in Betracht.The second agent can be in the form of both its concentrate and its ready-to-use water-diluted preparation form Contain builder substances, biocides and / or complexing agents. Examples of builder substances are alkali metal orthophosphates, polyphosphates, -silicates, -borates, -carbonates, -poly-acrylates and -gluconates. This Builders sometimes have complex properties and have a water softening effect. Instead of or in addition to this can stronger complexing agents such as 1-hydroxyethane-1,1-diphosphonic acid or 2-phosphonobutane-1,2,4-tricarboxylic acid become. There are also ethylenediaminetetraacetates or nitrilotriacetates into consideration.
Weiterhin betrifft die Erfindung die Mittelkombination in anwendungsfertiger Form, wobei der Kühlschmierstoff (das erste Mittel) und das wäßrige Reinigungs-/Korrosionsschutzmittel (das zweite Mittel) als wasserverdünnte Emulsion, Suspension oder Lösung vorliegen. Die Anwendungsform des ersten Mittels ist stets eine Öl-in-Wasser-Emulsion. Diese anwendungsfertigen wäßrigen Zubereitungen des ersten und des zweiten Mittels sind dadurch erhältlich, daß man die Konzentrate des ersten und des zweiten Mittels jeweils in einem Gewichtsverhältnis zwischen etwa 0,5 : etwa 99,5 bis etwa 10 : etwa 90 mit Wasser vermischt.The invention further relates to the combination of agents in a ready-to-use form, the cooling lubricant (the first agent) and the aqueous cleaning / corrosion protection agent (the second agent) as a water-diluted emulsion, Suspension or solution. The form of application of the first agent is always an oil-in-water emulsion. These ready-to-use aqueous Preparations of the first and the second agent can be obtained in that the concentrates of the first and the second agent each in one Weight ratio between about 0.5: about 99.5 to about 10: about 90 with Water mixed.
Hierbei führt das erfindungsgemäß einzusetzende Emulgatorsystem zu dem technischen Vorteil, daß die anwendungsfertigen wäßrigen Zubereitungen des ersten und des zweiten Mittels auch in weichem Wasser wenig zur Schaumbildung neigen. Zum Verdünnen der Konzentrate auf die Anwendungskonzentration kann daher nicht nur hartes Wasser, sondern auch mittelhartes Wasser (weniger als 12° dH) oder sogar weiches Wasser (weniger als 8° dH) verwendet werden. Selbst Wasser mit einer Härte von weniger als 4° dH kann verwendet werden, teilweise sogar vollentsalztes Wasser, ohne daß bei der Anwendung der Mittel Schaumprobleme auftreten. Die erfindungsgemäße Mittelkombination kann daher auch im Spritzverfahren im Temperaturbereich zwischen dem Gefrierpunkt und dem Siedepunkt der anwendungsfertigen Zubereitungen eingesetzt werden. Eine Mindesttemperatur für Spritzanwendungen muß im Gegensatz zu herkömmlichen Neutralreinigem nicht eingehalten werden. Selbstverständlich ist die erfindungsgemäße Mittelkombination auch in hartem Wasser ohne Nachteile einsetzbar. Here, the emulsifier system to be used according to the invention leads to the technical advantage that the ready-to-use aqueous preparations of The first and the second means little in soft water Tend to foam. For diluting the concentrates on the Application concentration can therefore not only hard water, but also medium hard water (less than 12 ° dH) or even soft water (less than 8 ° dH) can be used. Even water with a hardness of less than 4 ° dH can be used, sometimes even demineralized water, without the Use of the agent foam problems occur. The invention A combination of agents can therefore also be used in the spray process in the temperature range between the freezing point and the boiling point of the ready-to-use Preparations are used. A minimum temperature for In contrast to conventional neutral cleaners, spray applications do not have to be respected. Of course, the invention Medium combination can also be used in hard water without disadvantages.
Vorzugsweise wird das zweite Mittel als Reinigerlösung als sogenannter Neutralreiniger formuliert. Der übliche pH-Wert dieser sogenannten Neutralreiniger liegt in der anwendungsfertigen Form im Bereich von etwa 6,5 bis etwa 9.The second agent is preferably used as a cleaning solution as a so-called Neutral cleaner formulated. The usual pH of this so-called Ready to use neutral cleaner is in the range of about 6.5 to about 9.
In einem weiteren Aspekt betrifft die Erfindung ein Verfahren zur
spanabhebenden Metallbearbeitung unter Verwendung eines
wassergemischten Kühlschmierstoffs und anschließender Reinigung
und/oder Korrosionsschutzbehandlung, dadurch gekennzeichnet, daß man
als Kühlschmierstoff eine Öl-in-Wasser-Emulsion einsetzt, die
und
und daß man zur Reinigung und/oder Korrosionsschutzbehandlung eine wäßrige Lösung und/oder Suspension einsetzt, die das gleiche Emulgatorsystem wie der Kühlschmierstoff enthält.In a further aspect, the invention relates to a method for metal cutting using a water-mixed cooling lubricant and subsequent cleaning and / or corrosion protection treatment, characterized in that an oil-in-water emulsion is used as the cooling lubricant, which
and
and that for cleaning and / or anti-corrosion treatment, an aqueous solution and / or suspension is used which contains the same emulsifier system as the cooling lubricant.
Für Einzelheiten zur Zusammensetzung des als Kühlschmierstoff einzusetzenden Mittels und des Mittels, das man für die Reinigung und/oder Korrosionsschutzbehandlung verwendet, gilt hierbei das vorstehend ausgeführte.For details on the composition of the coolant agent to be used and the agent used for cleaning and / or Corrosion protection treatment used, the above applies here executed.
Im dem erfindungsgemäßen Verfahren setzt man als Kühlschmierstoff vorzugsweise eine Öl-in-Wasser-Emulsion ein, die dadurch erhältlich ist, daß man ein Konzentrat des ersten Mittels wie im Anspruch 1, dessen mögliche Zusammensetzung vorstehend näher erläutert ist, im Gewichtsverhältnis zwischen etwa 0,5 : etwa 99,5 bis etwa 10 : etwa 90 mit Wasser vermischt.In the process according to the invention, the cooling lubricant is used preferably an oil-in-water emulsion, which is obtainable by that a concentrate of the first agent as in claim 1, the possible composition is explained in more detail above, in Weight ratio between about 0.5: about 99.5 to about 10: about 90 with Water mixed.
Zur Reinigung und/oder Korrosionsschutzbehandlung setzt man vorzugsweise eine wäßrige Lösung oder Suspension ein, die dadurch erhältlich ist, daß man ein Konzentrat des zweiten Mittels, wie im Anspruch 1 und in der vorstehenden Beschreibung näher erläutert, im Gewichtsverhältnis zwischen etwa 0,5 : etwa 99,5 bis etwa 10 : etwa 90 mit Wasser vermischt. Wie vorstehend erläutert, kann hierfür jeweils auch mittelhartes oder sogar weiches Wasser verwendet werden, ohne daß bei der Anwendung des erfindungsgemäßen Verfahrens Schaumprobleme auftreten.For cleaning and / or anti-corrosion treatment, preferably an aqueous solution or suspension is available that a concentrate of the second agent, as in claim 1 and explained in more detail in the above description, in Weight ratio between about 0.5: about 99.5 to about 10: about 90 with Water mixed. As explained above, this can also be done in each case medium hard or even soft water can be used without the application of the process according to the invention foam problems occur.
Bei der Verwendung als Reinigungslösung setzt man das zweite Mittel in der anwendungsfertigen, wasserverdünnten Form so ein, daß die Temperatur im Bereich von etwa 15 bis etwa 80 °C liegt. Dabei kann die Reinigung in einer Tauchanlage oder in einer Spritzanlage erfolgen. Da die Spritzreinigung besonders effektiv ist, wählt man vorzugsweise dieses Verfahren. Hierbei zeigt sich der Vorteil der einzusetzenden Emulgatorkombination, daß im gesamten Temperaturbereich auch bei Verwendung von weichem Wasser keine Schaumprobleme auftreten. When used as a cleaning solution, the second agent is placed in the Ready-to-use, water-diluted form so that the temperature is in the range of about 15 to about 80 ° C. The cleaning in in a diving system or in a spraying system. Since the Spray cleaning is particularly effective, this is preferred Method. This shows the advantage of the one to be used Emulsifier combination that also in the entire temperature range Using soft water will not cause foam problems.
Das erfindungsgemäße Verfahren hat weiterhin den Vorteil, daß Reste von Kühlschmierstoff, die über die bearbeiteten Werkstücke in das Reinigungs-/Korrosionsschutzmittel eingetragen werden, allenfalls hinsichtlich der Ölkomponenten eine Belastung des Reinigungs-/Korrosionsschutzmittels darstellen. Da das Emulgatorsystem sowohl im Kühlschmierstoff als auch im Reinigungs-/Korrosionsschutzmittel das gleiche ist und der Kühlschmierstoff zumindest Korrosionsinhibitoren enthält, die mit denjenigen im Reinigungs-/Korrosionsschutzmittel verträglich sind, oder vorzugsweise Korrosionsinhibitoren enthält, die auch im Reinigungs-/Korrosionsschutzmittel vorliegen, führt eine Überschleppung von Kühlschmierstoff nicht zu einer Verunreinigung des Reinigungs-/Korrosionsschutzmittels, sondern ergänzt dieses vielmehr. Hierdurch wird zum einen die Standzeit dieses Mittels verlängert und zum anderen ist es seltener erforderlich, diese Wirkstoffe nachzudosieren. Damit führt die erfindungsgemäße Verfahrensfolge zu einem deutlich verringerten Stoffeinsatz und zu geringeren Entsorgungsaufwendungen. Der technische Zweck der spanabhebenden Metallbearbeitung mit anschließender Reinigung und/oder Korrosionsschutzbehandlung wird also mit einem im Vergleich zum Stand der Technik geringeren Stoffeinsatz und mit einer geringeren Umweltbelastung bei der Entsorgung der eingesetzten Mittel erreicht. Zusätzlich vermeidet man Schaumprobleme bei Stoffverschleppungen aus der Metallbearbeitungs- in die Reinigungszone. The inventive method has the further advantage that residues of Cooling lubricant that is in the cleaning / corrosion protection agent over the machined workpieces are entered, at most with regard to the Oil components a load of the cleaning / corrosion protection agent represent. Since the emulsifier system in both the cooling lubricant and Cleaning / anti-corrosion agent is the same and the cooling lubricant contains at least corrosion inhibitors that with those in the cleaning / corrosion protection agent are compatible, or preferably Contains corrosion inhibitors that are also in the cleaning / anti-corrosion agent there is a carryover of Coolant does not contaminate the cleaning / corrosion protection agent, but rather complements it. This will on the one hand prolongs the life of this product and on the other hand it is less often necessary to replenish these active ingredients. So that leads Process sequence according to the invention to a significantly reduced Use of materials and lower disposal costs. The technical Purpose of metal cutting with subsequent Cleaning and / or anti-corrosion treatment is done with an im Compared to the prior art, less material and with a lower environmental impact when disposing of the funds used reached. In addition, you avoid foam problems in case of carryover from the metal processing to the cleaning zone.
Die nachstehenden Tabellen enthalten Beispiele für Konzentrate für das erste und
zweite Mittel der erfindungsgemäßen Mittelkombination. In dem anschließend
beschriebenen Korrosionsschutztest wird gezeigt, daß ein Überschleppen von
Kühlschmierstoff in das Reinigungs-/Korrosionsschutzmittel dessen
Korrosionsschutzwirkung nicht verschlechtert, sondern eher verbessert.
Aus dem Konzentrat des zweiten Mittels gemäß Tabelle 3 wurden anwendungsfertige Reinigungs-/Korrosionsschutzlösungen hergestellt und hiermit ein Korrosionsschutztest nach DIN 51360/2 durchgeführt. Hierfür werden Gußeisenspäne auf einem Rundfilter mit der Lösung benetzt und 2 Stunden lang in einer Glasschale bei Raumtemperatur gehalten. Anschließend werden die Korrosionsabzeichen auf dem Filterpapier visuell beurteilt und in die Korrosionsgrade 0 bis 4 eingeteilt. Dabei bedeuten Korrosionsgrad 0: keine Korrosion, Korrosionsgrad 1: Spuren von Korrosion, Korrosionsgrad 2: leichte Korrosion, Korrosionsgrad 3: mäßige Korrosion und Korrosionsgrad 4: starke Korrosion.From the concentrate of the second agent according to Table 3 ready-to-use cleaning / corrosion protection solutions are produced and hereby a corrosion protection test according to DIN 51360/2 was carried out. For this be Cast iron chips on a round filter wetted with the solution and for 2 hours kept in a glass bowl at room temperature. Then the Corrosion badges visually assessed on the filter paper and into the Corrosion levels 0 to 4 classified. Degree of corrosion means 0: none Corrosion, degree of corrosion 1: traces of corrosion, degree of corrosion 2: slight Corrosion, degree of corrosion 3: moderate corrosion and degree of corrosion 4: severe Corrosion.
Bei einem 2 %igen Ansatz des Konzentrats in Brauchwasser (pH-Wert 9,72) ergab sich ein Korrosionsgrad 4, bei 3 %igem Ansatz (pH-Wert 9,75) ein Korrosionsgrad 0 und bei 4 %igem Ansatz (pH-Wert 9,78) ebenfalls ein Korrosionsgrad von 0. With a 2% batch of the concentrate in industrial water (pH 9.72) there was a degree of corrosion 4 with a 3% mixture (pH 9.75) Degree of corrosion 0 and also with a 4% mixture (pH 9.78) Degree of corrosion of 0.
Das Überschleppen des Kühlschmierstoffs in die Reiniger-/Korrosionsschutzlösung wurde dadurch simuliert, daß die vorstehend beschriebenen anwendungsfertigen Lösungen zusätzlich mit 0,2 Gew.-% des Konzentrats gemäß Tabelle 2 versetzt wurden. Anschließend wurde wieder ein Korrosionsschutztest gemäß DIN 51360/2 durchgeführt. Ergebnisse: 2 %iger Ansatz (pH 9,66): Korrosionsgrad 2, 3 %iger Ansatz (pH 9,72): Korrosionsgrad 0, 4 %iger Ansatz (pH 9,75): Korrosionsgrad 0.The cooling lubricant is carried over into the cleaning / corrosion protection solution was simulated by the above described ready-to-use solutions additionally with 0.2 wt .-% of Concentrate according to Table 2 were added. Then was on again Corrosion protection test carried out in accordance with DIN 51360/2. Results: 2% Batch (pH 9.66): degree of corrosion 2, 3% batch (pH 9.72): degree of corrosion 0, 4% mixture (pH 9.75): degree of corrosion 0.
Ein Überschleppen des Kühlschmierstoffs in die Reiniger-/Korrosionsschutzlösung verschlechtert also den Korrosionsgrad bei 3 und 4 %igem Ansatz des Reinigerkonzentrats nicht, bei 2 %igem Ansatz wird der Korrosionsschutz erheblich verbessert.A dragging of the cooling lubricant into the cleaner / corrosion protection solution deteriorates the degree of corrosion with 3 and 4% of the Cleaner concentrate not, with a 2% mixture the corrosion protection significantly improved.
