Definitions

  • the invention relates to a composition for the production of a lubricant composition, the use of this composition as a performance additive in lubricant compositions, preferably in cooling lubricant compositions, in particular in cooling lubricant solutions, a lubricant composition and methods for producing the same.
  • Cooling lubricants are often used when processing metal.
  • the term “cooling lubricant” according to DIN 51385 describes a metalworking medium that is used in particular to support metalworking or forming processes or to influence the structure (see also AR Eyres, RN Mather, J. Inst. Petr. 59 (565), p. 9- 17, 1973).
  • Cooling lubricants can be divided into the main groups of non-water-miscible and water-miscible cooling lubricants, with the water-miscible further differentiating between emulsifiable and water-soluble cooling lubricants.
  • Cooling lubricants can make a significant contribution to the economy of metalworking processes. For example, their use can significantly influence the service life of the processing tools used and / or the quality of the material.
  • a cooling lubricant should have a cooling and friction-reducing effect if possible. If the cooling effect is in the foreground, water-miscible cooling lubricants are mainly used for this. However, these often have poorer lubricating performance and resistance to microorganisms compared to non-water-miscible cooling lubricants. In addition, they tend to unwanted foaming and are often susceptible to different water qualities (especially with regard to the water hardness used).
  • non-water-miscible namely oil-based cooling lubricants are used. These are characterized above all by their good friction-reducing properties.
  • a disadvantage of the non-water-miscible cooling lubricants is that their cooling effect is low compared to water-miscible cooling lubricants due to the low specific heat capacity and thermal conductivity.
  • the components are more difficult to clean after processing than when using water-miscible cooling lubricants.
  • Another problem is the oil mist, which can occur when using the oils, especially at high cutting speeds. The aerosols it contains lead to health-endangering lung loads. The oil mist may also be easily flammable, so that adequate safety precautions must be taken.
  • cooling lubricants can also be emulsions that combine the advantageous properties of the cooling effect and the reduction in friction (W. Baumann, B. Herberg-Liedtke, Chemicals in Metal Processing, Berlin; Heidelberg Springer, 1995, pp. 37f).
  • An emulsion is a disperse system that is created by mixing two liquids that are not soluble in one another. They show a relatively good lubrication performance and an acceptable cooling effect.
  • the European patent application EP 1 319 703 A1 discloses water-based cooling lubricant emulsions for metal forming. After drying, these form a lubricating film on the workpiece.
  • the emulsions also contain emulsified paraffin wax to reduce friction.
  • Critical to coolant emulsions are - in addition to the high manufacturing costs - above all the instability of the emulsion, especially against foreign oil input, salt load and Water hardness, as well as the colonization of the emulsion with microorganisms.
  • the attack on fungi and bacteria reduces the corrosion protection behavior of the emulsions and leads to health problems for the personnel.
  • the emulsion loses stability due to the attack by microorganisms, which can cause malfunctions.
  • emulsions have a tendency to foam. It is therefore typical for lubricant emulsions that they contain a large number of auxiliaries, such as, for example, biocides, emulsifiers or defoamers. In addition to the oil phase present in emulsions, these auxiliaries represent a challenge when it comes to maintaining the emulsion, occupational safety and cleaning the components.
  • auxiliaries represent an additional health burden for the user and the environment, since these substances are mostly compounds, in particular organic compounds with a relatively low molecular weight, which are preferably at elevated temperatures - as is customary in metal-cutting or forming processes - go into the gas phase and thus potentially pose a health and environmental risk.
  • the object of the invention is accordingly to provide a composition for producing a lubricant composition and a lubricant composition which reduces or overcomes at least one of the disadvantages mentioned.
  • the object is achieved by a composition for producing a lubricant composition
  • a composition for producing a lubricant composition comprising a component (A) and at least one metal salt (M).
  • Component (A) consists of one or more inorganic salts, while the metal in the metal salt (M) is selected from the group consisting of the transition metals, metals of the 3rd main group, metals of the 4th main group, metals of the 5th main group or mixtures from that.
  • the composition is further characterized in that when water is added at room temperature, it is homogeneous Solution arises.
  • Component (A) is preferably not identical to the metal salt (M).
  • composition according to the invention can contain a component (B).
  • Component (B) consists of one or more compounds each containing at least one structural unit XC.
  • C is carbon and X is silicon (Si), nitrogen (N), oxygen (O), phosphorus (P) or sulfur (S).
  • X and C are linked to one another by means of an s bond, p bond or ionic bond.
  • composition can also be obtained by bringing component (A) together with at least one metal salt (M), preferably with two metal salts (M).
  • component (B) is optional. Unless explicitly stated otherwise, all further preferred embodiments therefore relate to these two versions of the composition according to the invention.
  • composition according to the invention is suitable for providing lubricant compositions which have a high lubricating performance and also a good cooling performance.
  • the performance of this lubricant composition is comparable to, or even better than, known coolant emulsions. This was demonstrated, for example, when it was used in metal cutting or when metal, in particular steel and aluminum, was formed (see Example 3).
  • the lubricant compositions provided according to the invention also have the advantage over the prior art that they manage with fewer, preferably even completely without auxiliaries and / or additional performance additives to achieve the desired lubrication performance. For example, they show good biostability even without the addition of biocides (see Example 7).
  • the use of defoamers can also be dispensed with (see Example 6).
  • the possible redox reactions when a metallic material comes into contact with an aqueous medium can surprisingly be restricted, preferably even prevented, by adding a metal salt (M).
  • the metal salt (M) acts as an "electronic buffer".
  • composition according to the invention can furthermore make it possible to reduce the proportion of pH stabilizers as an auxiliary or even to dispense with them entirely.
  • composition according to the invention is the easier separation of foreign oil from a lubricant composition produced with the composition. This is especially true if it is a lubricant solution. If the liquid lubricant, especially the cooling lubricant solution, is contaminated with foreign oils during use, it can simply be skimmed off. Oils generally have a lower density than water and are poorly or not at all soluble in water. Accordingly, oils and / or fats preferably collect on the surface of the lubricant solution and can be easily removed there.
  • the lubricant composition according to the invention in particular the cooling lubricant solution, shows a certain insensitivity to different degrees of hardness of the water (example 5).
  • Water hardness is the concentration of the salts of alkaline earth metals dissolved in water, in particular of the alkaline earth metal ions, preferably calcium and magnesium. If the concentration of alkaline earth metals is high - the water is very hard - the ions it contains can be combined with ionic compounds that are in the Lubricant composition are included, react. In the case of cooling lubricant emulsions in particular, a high sensitivity to hard water is observed, since the emulsions generally contain emulsifiers (for example fatty acids). These can react with the alkaline earth metal ions. This often results in unwanted deposits that can adversely affect the performance of the cooling lubricants. This makes complex softening processes necessary, which can result in increased lubricant costs.
  • compositions according to the invention only contain components which are water-soluble and form a homogeneous solution in water, lubricant compositions formed therewith preferably have no emulsifiers. Therefore, they show a greater insensitivity to unwanted reactions with ions of the alkaline earth metals from hard water. Thus, the formation of unfavorable deposits or an associated loss of performance can be reduced. In addition, there is no need for complex softening processes.
  • solution is defined as a homogeneous distribution of molecularly disperse particles in a liquid medium. All particles are present in a molecular dispersion. They therefore all form a common phase. A solution is therefore different from a multi-phase system in which one phase is the dispersant in which the other phases are distributed (i.e. dispersed), such as an emulsion or suspension.
  • composition according to the invention is therefore at the same time characterized in that it does not form an emulsion or suspension after being brought together with water and that no mini, nano or microemulsion is formed or is contained therein.
  • micelles, vesicles or mesophases, such as lamellar systems are not present after the addition of water.
  • the bond between X and C includes compounds with an element-carbon-o bond, a TT bond or an ionic bond.
  • the elements (X) of the element-carbon bonds are selected independently of one another from silicon (Si), nitrogen (N), oxygen (O), phosphorus (P) or sulfur (S). If several salts and / or organo-element compounds are contained in the compositions according to the invention, these can interact and / or react with one another. In particular, ion exchange reactions are possible in the case of the inorganic or organic element salts.
  • a composition according to the invention preferably comprises an inorganic salt of component (A), at least one metal salt (M) and optionally at least one compound of component (B).
  • compositions according to the invention are therefore obtainable by contacting at least two inorganic salts of component (A) with at least two metal salts (M) and optionally one or more compounds of component (B) which are defined here or from at least one inorganic salt of component (A) with at least one metal salt (M) and optionally at least one compound of component (B), which is as defined herein.
  • the composition according to the invention contains both component (A), at least one metal salt (M) and component (B). It is particularly preferred that the composition according to the invention consists of these components. However, the composition according to the invention very particularly preferably consists of component (A) and at least one metal salt (M). The metal salt (M) is very particularly preferably unequal to component (A).
  • compositions are used to produce a lubricant composition
  • the composition itself that is to say without further additives, auxiliaries or solvents - can constitute the lubricant composition.
  • the composition can be used in solid or liquid form as a lubricant composition.
  • the composition for the production of the lubricant composition can also contain other constituents, such as, for. B. Additives such as a corrosion inhibitor or a pH control agent may be added to a solvent if necessary (see below).
  • the changes The surface tension of water is reduced by adding component (A) or component (B) or mixtures thereof by a maximum of 10%, preferably by a maximum of 7.5%, particularly preferably by a maximum of 5% and in particular by a maximum of 2%.
  • the "surface tension” is also referred to as specific surface energy. It is a force that acts on liquids at the boundary with a gas or vacuum tangential to the interface. By adding certain substances, the surface tension of liquids can be changed significantly.
