Definitions
- the invention relates to a method for producing a cooling emulsion, in particular for use as drilling, cutting and grinding aids in the metalworking industry, in which water-insoluble organic substances are emulsified in water, and to the use of the cooling emulsion produced by the method.
- Drilling, cutting and grinding emulsions are generally used to cool saws, grinders, drills and the like in order to dissipate the heat that occurs when machining workpieces and thereby avoid increased wear on the tools, which occurs when the workpieces are excessively heated.
- So far so-called drilling oils have been used for this purpose, which were essentially water-solubilized mineral oils.
- the water solubility of the mineral oils is usually achieved by adding sodium hydroxide solution to a mixture of resin oil, olein or the like until the end product can be smoothly emulsified with water.
- sulfide leachate, tar oils and waste oils are also used, which are made water-soluble essentially using the same process.
- Such products are often mixed with disinfectant and rust-preventing components such as nitrite, chromium compounds or other substances.
- drilling oils are not biodegradable according to the prior art.
- the invention has for its object to provide a method for producing a drilling oil or a drilling oil, the use of which does not cause skin damage, which is biodegradable to avoid waste problems, and good heat dissipation to achieve a long service life of the tools whose use it is used to achieve.
- the object is achieved according to the invention in that initially a mixture of about 3 to 15% by weight of natural wax (s) of animal and / or vegetable origin, 0.1 to 0.45% by weight of a nonionic surfactant, the rest about 50% by weight of water, about 37.5% by weight of diethanolamine (s) and about 12.5% by weight of triethanolamine (s), aqueous di / tri-entanol mixture, prepared, then the mixture is brought to a boil with stirring, after dispersion of the wax portion is cooled to a reaction temperature with stirring and after amination of the wax portion by the di / tri-ethanol mixture is cooled down to the use temperature.
- the invention further relates to the use of the cooling emulsion produced by the process according to the invention in approximately 2.5-5% (wt.%) Aqueous solution with a pH of 8-9 as drilling, cutting or grinding aid.
- the cooling emulsion according to the invention also has better properties than previously known emulsions in its mode of action as drilling oil.
- the drilling, cutting and grinding emulsions have an above-average heat dissipation, so that a rapid cooling of the work place by heat dissipation to the total coolant in the reservoir causes. It was also observed that, for example, the cut surfaces in cast iron (gray cast iron) have smoother cut surfaces when using the cutting emulsion according to the invention than could previously be achieved with conventional ones, surprisingly less wear on the tools being observed.
- the emulsion according to the invention is anti-corrosive and does not lead to the occurrence of oxidation in the processed objects.
- Deviations in the composition of the concentration in particular a reduction in the content of the drilling emulsions according to the invention leads to increased wear of the tools, poorer heat dissipation, and zer cracked cut surfaces, as well as material breakage on the workpiece.
- Another advantage of the drilling, cutting and grinding emulsions according to the invention is that they are completely biodegradable and therefore the previously necessary collection and destruction of the used drilling oils in a flaring system is eliminated. Instead, used drilling emulsions can simply be discharged into the sewage systems, in which they can be processed without affecting the receiving water of sewage systems.
- Organic and / or vegetable waxes preferably from plants of the Copernicia genus with an addition of a commercially available emulsifier, preferably a nonionic, are usually processed in the process according to the invention.
- About 1 to 3 parts by weight are used per 10 to 15 parts by weight of wax.
- 41 parts by weight of a DiITri-ethanol mixture, and an anticorrosive metal-wetting disinfectant with bactericidal and fungicidal properties which prevent the growth of virus types, salmonella, adhesives and other problem germs are added.
- About 1 to 2% by weight of preservative of the overall formulation is preferably used.
- a lemon peel extract with skin-protecting properties can be mixed in up to 1% of the total formulation.
- An emulsion according to the invention is usually prepared by heating the wax, emulsifier, di- and tri-ethanolamines together and, after dissolving the wax fraction, cooling with stirring to the point of transition.
- the transition temperature is usually in the range of about 84-93 ° C.
- preservative and, if necessary, lemon peel extract are added.
- This emulsion obtained in this way is diluted 20 to 30 times for use as a grinding, drilling or cutting aid.
- This dilution can, if necessary, only be carried out using water at the place of use.
- a commercially available mixture which consists of 75 parts of di- and 25 parts of tri-ethanolamine and is in 50% aqueous solution is usually used as the di-triethanol mixture.
- the wax content of the emulsion according to the invention should be between about 10 to 15%.
- the preferred preservative is an aqueous solution of dioctylaminoethylglycine lactate and alkylaminoethylglycine hydrochloride, as sold by Goldschmidt, Essen / Ruhr, Goldschmidtstrasse under the trademark "TEGO”.
- This emulsion can be used as a concentrate for the production of cutting, drilling or grinding emulsions.
- 15 parts by weight of a wax are mixed with 80 parts by weight of a mixture consisting of 50% by weight of H 2 O, 12.5% of tri-ethanolamine and 37.5% by weight of di-ethanolamine and 0.1% by weight of a commercially available , nonionic emulsifier boiled and cooled to a temperature of 50 ° C after complete amination.
- a commercially available preservative is then added with 1% of the total mixture.
- This emulsion can be diluted 35 times with water for use as a grinding, drilling or cutting emulsion, with a pH between 8 and 9.
- An emulsion is prepared as described in Example 1, 3 parts by weight of amino soap being added to the starting mixture with stirring.
- the emulsion made with amino acid was also suitable for use as a drilling, grinding or cutting aid.
- An emulsion was prepared as described in Example 2, except that 0.5-2% by weight sodium soap was added to the starting mixture.
- An emulsion was prepared as described in Example 1 or 2, with 0.5-2% by weight potassium soap being additionally added to the starting mixture.
- Example 1 The emulsion of Example 1 was diluted 35 times with water for use as a cutting oil, this diluted emulsion having a pH of 10. A circular saw with a circular saw blade of 15 mm in diameter was used. When using the emulsion according to the invention, the separating sheet had to be replaced after 2800 separations.
- a comparison test with a conventional cutting oil showed that the circular saw blade had to be replaced after 1,200 separations. It was also observed that the machine ran less smoothly and smoothly than when the emulsion according to the invention was used as the cutting oil.
- a 3% mixture of the emulsion of Example 2 in water with a pH between 8 and 9 was used as the drilling emulsion in a radial drilling machine.
- the drilling machine is working satisfactorily, in particular no rust formation has been observed on the metal parts which came into contact with the drilling emulsion. No sticking of the machine or parts was observed.
- the emulsion according to the invention is suitable as a drilling emulsion.
- Example 2 A 3% mixture of the emulsion of Example 1, diluted 35 times with water, was used in an MSO grinding machine.
- the emulsion according to the invention is suitable as a grinding emulsion.
