Definitions

  • metal machining 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 using a machining tool. Examples of such machining
  • Metalworking 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. This has the tasks: lubricating the tool to avoid welding and overheating, dissipating the heat generated and removing the chips or other metal particles formed.
  • the cooling lubricant must be such 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 relates to oil-in-water emulsions and their water-miscible concentrates, that is to say cooling lubricants which contain an oil component.
  • cooling lubricants which contain an oil component.
  • the cleaning is intended in particular to remove residues of the cooling lubricant, but also other dirt and metal particles which are still adhering. 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.
  • 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 ingredients, which have to be disposed of at the end of the service life of the detergent, which has an environmental impact and is also economically disadvantageous because of the required use of materials.
  • the invention has for its object to provide a means and process combination for metal cutting using a water-mixed cooling lubricant and subsequent cleaning and / or corrosion protection of the machined metal parts with an aqueous cleaning / corrosion protection agent, in which the ingredients of the cooling lubricant and aqueous cleaning / corrosion protection agents are coordinated with one another in such a way that ingredients of the cooling lubricant supplement the cleaning / corrosion protection agent or at least do not negatively influence it.
  • the cooling lubricant for the cleaning / corrosion protection agent does not represent a "contamination", but rather complements it. This enables the cleaning / corrosion protection agent itself to use less active ingredients. The service life of the cleaning / corrosion protection agent is also reduced without bathroom care.
  • the emulsifier system to be used according to the invention is known from German patent application DE-A-197 03 083. Compared to conventional emulsifier systems, it has the advantage that it has little tendency to foam in soft to medium-hard water, that is to say in water with less than 12 ° and in particular with less than 8 ° dH.
  • 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
  • unalkoxylated fatty alcohols with 12 to 24 carbon atoms the Distillation residue or their alkoxylation products with up to a maximum of 3 propylene oxide units on average.
  • the approximate weight ratio given must be observed. Distillation residues of fatty alcohols with 12 to 24 carbon atoms are available from Henkel KGaA, Düsseldorf, under the name Pemil R RU.
  • Non-polar or polar oils of petrochemical or native origin can be used as the oil component in the first agent.
  • Synthetic oil components are also suitable. Examples of oil components that can be used are paraffinic or naphthenic mineral oil, dialkyl ethers with 12 to 20 carbon atoms and ester oils.
  • the ester oils can be of vegetable or animal origin and can be present as esters of glycerol with 3 fatty acids (so-called fatty acid triglycides). An example of such an ester oil is rapeseed oil.
  • Such ester oils can also be obtained synthetically by esterifying glycerol with selected fatty acids or by transesterifying natural fats and oils with other fatty acids.
  • the corrosion inhibitors which are used according to the invention both in the aqueous cooling lubricant and in the aqueous cleaning / corrosion protection agent and in each case 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 carboxylic acids being present partially or completely as salts. 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, which together form salt react. Furthermore, the alkanolamines can be used as such, the carboxylic acids as alkali metal salts, preferably as potassium salts.
  • Carboxylic acids and alkali metal hydroxides are formed as an equilibrium mixture from the
  • Anions are present in the case of carboxylic acids.
  • the first agent (the cooling lubricant or its concentrate) and the second agent (the cleaning / corrosion protection agent or its concentrate) can contain the same corrosion inhibitors. However, this is not necessary. It is only necessary to ensure that both the first agent and the second agent each contain one or more of the above-mentioned corrosion inhibitors. However, it is preferred that the first agent contain one or more corrosion inhibitors that are also present in the second agent. If the two agents are available in a ready-to-use form during operation, dragging cooling lubricant residues into the cleaning / corrosion protection agent automatically results in a combination of corrosion inhibitors over time, which is also present in the first agent.
  • the first agent for use in metal cutting, the first agent, the water-mixed cooling lubricant, can in principle be mixed together on site by dissolving or emulsifying the individual components in the desired concentrations in water.
  • water-miscible cooling lubricants in the form of a
  • Application concentration can be diluted.
  • the aqueous cleaning / anti-corrosion agent can also be prepared by dissolving or suspending the individual active ingredients in water in the required concentrations on site.
  • the preferred procedure here is to bring to the market concentrates of the cleaning / corrosion protection agent, which are diluted on site with water in the required ratio.
  • both the first agent and the second agent can be present as a water-miscible concentrate in the agent combination according to the invention.
  • the first agent preferably contains 10 to 40% by weight of the oil components, 10 to 40% by weight of the emulsifier system and 20 to 40% by weight of corrosion inhibitors.
  • the second agent preferably contains 10 to 40% by weight of emulsifier system and 20 to 40% by weight of corrosion inhibitors. Both agents can optionally also contain water and / or further active substances and auxiliaries, the proportions of course being chosen such that the sum of the components gives 100% by weight.
  • the first agent may contain, as further active ingredients and excipients: lubricating additives in general and in particular so-called "Extreme Pressure" - additives (EP additives), further corrosion inhibitors such as boric acid or alkylphosphonic acids as well as additional alkanolamines and solubilizers such as glycols, 'glycerol or sodium cumene sulfonate

  • solubilizers such as glycols, 'glycerol or sodium cumene sulfonate
  • the first agent can consist exclusively of the oil component, the emulsifier system and the corrosion inhibitors. Due to the manufacturing process, however, it generally contains small amounts of water, for example in the range from about 2 to about 10% by weight. These either get into the agent via the raw materials used, for example if carboxylic acids are used as corrosion inhibitors, which are neutralized with aqueous potassium hydroxide solution. In addition, the other active substances and auxiliaries mentioned above may optionally be present.
  • the second agent inevitably contains at least 20% by weight of water and / or further active ingredients and auxiliaries as a concentrate. In the simplest case, apart from the emulsifier system and the corrosion inhibitors, it also contains 20 to 70% by weight of water and no other active ingredients.
  • the second agent can also contain builder substances, biocides and / or complexing agents both in the form of its concentrate and its ready-to-use water-diluted preparation form.
  • builder substances are alkali metal orthophosphates, polyphosphates, silicates, borates, carbonates, polyacrylates and gluconates. Some of these builder substances have complexing properties and therefore have a water-softening effect. Instead of or in addition to this, stronger complexing agents such as 1-hydroxyethane-1, 1-diphosphonic acid or 2-phosphonobutane-1, 2,4-tricarboxylic acid can be used become. Ethylene diamine tetraacetates or nitrilotriacetates are also suitable.
  • the invention 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) being present as a water-diluted emulsion, suspension or solution.
  • the application form 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 agent have little tendency to foam even in soft water. 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 to dilute the concentrates to the application concentration. Even water with a hardness of less than 4 ° dH can be used, sometimes even demineralized water, without foam problems when using the agents.
  • the agent combination according to the invention can therefore also be used in the spraying process in the temperature range between the freezing point and the boiling point of the ready-to-use preparations.
  • the agent combination according to the invention can also be used in hard water without disadvantages.
  • the second agent is preferably formulated as a cleaning solution as a so-called neutral cleaner.
  • the usual pH value of these so-called neutral cleaners in the ready-to-use form is in the range from about 6.5 to about 9.
  • the cooling lubricant used is preferably an oil-in-water emulsion which can be obtained by concentrating the first agent according to claim 4, the possible composition of which is explained in more detail above, in a weight ratio of between about 0.5 : about 99.5 to about 10: about 90 mixed with water.
  • an aqueous solution or suspension is preferably used, which can be obtained by adding a concentrate of the second agent, as explained in more detail in claim 4 and in the description above, in a weight ratio between about 0.5: about 99.5 to about 10: about 90 mixed with water.
  • a concentrate of the second agent as explained in more detail in claim 4 and in the description above, in a weight ratio between about 0.5: about 99.5 to about 10: about 90 mixed with water.
  • medium-hard or even soft water can be used for this in each case without foam problems occurring when the process according to the invention is used.
  • the second agent When used as a cleaning solution, the second agent is used in the ready-to-use, water-diluted form in such a way that the temperature is in the range from about 15 to about 80 ° C.
  • the cleaning can be done in a dipping system or in a spraying system. Since spray cleaning is particularly effective, this method is preferred. This shows the advantage of the emulsifier combination to be used that no foam problems occur in the entire temperature range, even when using soft water.
  • the method according to the invention also has the advantage that residues of cooling lubricant which are introduced into the cleaning / corrosion protection agent via the machined workpieces represent a load on the cleaning / corrosion protection agent at most with regard to the oil components.
  • the cooling lubricant contains at least corrosion inhibitors that are compatible with those in the cleaning / corrosion protection agent, or preferably contains corrosion inhibitors that are also present in the cleaning / corrosion protection agent
  • Carryover of cooling lubricant does not lead to contamination of the cleaning / corrosion protection agent, but rather complements it. On the one hand, this extends the service life of this agent and, on the other hand, it is less often necessary to replenish these active ingredients.
  • the method sequence according to the invention thus leads to a significantly reduced use of materials and to lower disposal costs.
  • the tables below contain examples of concentrates for the first and second agent of the agent combination according to the invention.
  • the corrosion protection test described below shows that dragging coolant into the cleaning / corrosion protection agent does not worsen its corrosion protection effect, but rather improves it.
  • Example 1 for a concentrate of a cooling lubricant emulsion (first agent), concentration data in% by weight
  • Example 2 for a concentrate of a cooling lubricant emulsion (first agent), concentration data in% by weight
  • Table 3 Example of a concentrate of a cleaning solution (second agent), concentration data in% by weight
  • Ready-to-use cleaning / corrosion protection solutions were prepared from the concentrate of the second agent according to Table 3 and a corrosion protection test according to DIN 51360/2 was carried out. For this, cast iron chips are wetted with the solution on a round filter and kept in a glass bowl at room temperature for 2 hours. The corrosion marks on the filter paper are then assessed visually and divided into degrees of corrosion 0 to 4. Degree of corrosion 0 means no 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.
