Definitions
- the present invention relates to new technical fluids for metalworking.
- Oil-in-water emulsions are generally used as liquids for metalworking. It is important here that the oil is easily emulsifiable and that the emulsion formed is stable and has good corrosion protection and lubrication properties.
- emulsions contain an emulsifier and additives which, among other things, simultaneously improve the lubricating effect and corrosion protection properties. Petroleum sulfonates with an average molecular weight of 400 to 600 are frequently used as emulsifiers and rust preventives in such formulations, but they have a high viscosity and foam strongly, which is not desirable.
- the present invention therefore relates to aqueous emulsions of the oil-in-water type for metalworking, characterized in that they contain a sec. Alkanesulfonate or a mixture of such a salt with petroleum sulfonates in the form of the alkali salt with a molecular weight of 400 to 600 in a ratio of 1: 3 to 3: 1, preferably in a ratio of 1: 1.
- the amount of sec. Alkanesulfonate or the mixture of this salt with the petroleum sulfonates in the emulsion is preferably between 0.10 and 2 parts based on 100 parts of the emulsion.
- alkanesulfonic acids for example, mixtures obtainable according to the processes described by C. Bluestein and BR Bluestein (see Manufacturer Science Series - Volume 7 - Anionic Surfactants - Part 11, pages 331-334 - Marcel Dekker Verlag, New York, 1976) from the sulfonation of (C 10 -C 18 ) paraffins by using sulfuric anhydride in the presence of oxygen under UV radiation. Examples of these are in particular (C 10 -C 18 ) -alkanesulfonic acids with a sulfo group on the second carbon atom.
- the salts in particular the sodium and potassium salts, can be obtained by known methods by neutralizing these acids with sodium hydroxide solution or potassium hydroxide solution.
- the petroleum sulfonates used are preferably oil-soluble sodium alkylarylsulfonates with one or more alkyl chains, such as the sodium salt of polypropylenebenzenesulfonic acid. These petroleum sulfonates arise, among other things, as by-products in the treatment of petroleum with sulfuric acid.
- the emulsions according to the invention naturally contain water, a mineral oil and the constituents customary for such emulsions, such as soaps, fatty acid alkanolamides, alkyl or arylsulfamidocarboxylic acid salts, nonionic surfactants, sodium nitrite, triethanolamine borate or phosphoric acid derivatives.
- a mineral oil such as soaps, fatty acid alkanolamides, alkyl or arylsulfamidocarboxylic acid salts, nonionic surfactants, sodium nitrite, triethanolamine borate or phosphoric acid derivatives.
- the present invention further relates to concentrates for the production of the above emulsions with a content of 1 to 10%, preferably 3 to 6%, of these concentrates.
- Such concentrates contain 3 to 20% sec. Alkanesulfonates or a mixture of such a salt with petroleum sulfonates in the form of sodium salts, a mineral oil or a spindle oil with or without the additives customary for emulsions.
- Table III shows the synergistic effect on the viscosity of the emulsions after combining the alkanesulfonates according to the invention with the petroleum sulfonate.
- the cleavability listed in Tables I and II as the physical property of the emulsion it should be noted that this is a criterion for the dispersibility of the oil phase with simple manual stirring. This property and the stability (in hours) are assessed visually.
- the pH of the 3% emulsions is determined using a glass electrode.
- the foaming power is determined at 25 ⁇ 3 ° C according to Citroen standard LC 1425 as follows: 1 liter of a 3% aqueous emulsion is left for 5 hours by means of a pump at a speed of 250 Vh. circulate. Then let the emulsion flow through a nozzle with an inner diameter of 5 mm from a height of 75 mm into a test tube of 2 liters with a diameter of 80 mm and lead it back through a nozzle at the bottom of the test tube. After the pump has been turned off, measure the volume of the liquid in the test tube after 5 hours (1000 indicates that there is no foaming). The foaming power is given in cm 3 .
- the viscosity values in Table 111 above are given in millipascal seconds (mPas). They were determined at 50 ° C using a Brookfield viscometer, type RVT with a No. 5 rotor and a speed of 10 revolutions per minute. The values obtained show a clear drop in viscosity when mixtures are used.
