Description
Die Erfindung bezieht sich auf Mineralölemulsionen, wie sie in der metallverarbeitenden Industrie beim Schneiden und Schleifen z. B. von Getrieben, Werkzeugen, Kurbelzapfen, Kugellagern, Pumpenzylindern verwendet werden. Ziel der Erfindung ist es, das Schäumen dieser Mineralölpräparate im Gebrauch zu verhindern oder zu verzögern. Diese Emulsionen bestehen gewöhnlich aus einem Mineralöl, einem emulgierenden Mittel und Wasser. Das Mineralöl kann eine leichte Petroleumschmierölfraktion, ein Spindelöl, ein Weißöl oder ein ähnlicher Ausschnitt sein. Rohöldestillate aus paraffinischen oder naphthenischen ölen mit Viscositäten zwischen 1,850E und 5,7° E bei 380C sind im allgemeinen brauchbar. Als emulsionsbildende Stoffe können Naphthenate oder Sulfopate von Alkalien oder Stickstoffbasen, also Na-The invention relates to mineral oil emulsions such as those used in the metalworking industry for cutting and grinding. B. can be used by gears, tools, crank pins, ball bearings, pump cylinders. The aim of the invention is to prevent or delay the foaming of these mineral oil preparations during use. These emulsions usually consist of a mineral oil, an emulsifying agent and water. The mineral oil can be a light petroleum lubricating oil fraction, a spindle oil, a white oil, or the like. Crude oil distillates from paraffinic or naphthenic oils having viscosities between 1.85 and 5.7 E 0 ° E at 38 0 C are generally useful. Naphthenates or sulfopates of alkalis or nitrogen bases, i.e. Na-
trium-, Kalium-, Oniumsalze zur Verwendung ao kommen. Auch organische Naphthenate, wie die des Di- oder Triäthanolamins, sind brauchbar. Im allgemeinen ist es gut, Mischungen von Naphthenaten und Sulfonaten z. B. im Verhältnis von 1 : 4 zu verwenden. Es wurde festgestellt, daß die Naphthenate die Schaumbildung der Emulsionen im Gebrauch sehr stark begünstigen, auch sind sie höher wasserlöslich als die Sulfonate. Der emulgierende Stoff kann 5 bis 4O°/0 des Mineralöls ausmachen.trium, potassium, onium salts come to use ao. Organic naphthenates, such as those of diethanolamine or triethanolamine, can also be used. In general it is good to use mixtures of naphthenates and sulfonates e.g. B. to use in a ratio of 1: 4. It was found that the naphthenates promote the foaming of the emulsions very strongly during use, and they are more water-soluble than the sulfonates. The emulsifying agent may constitute 5 to 4O ° / 0 of the mineral oil.
Es ist bei der Verwendung derartiger Emulsionen in der mechanischen Metallbearbeitung eine bekannte Tatsache, daß infolge der unvermeidlichen Bewegung der Emulsion bedeutende Mengen Schaum gebildet werden, die nicht nur die mechanische Arbeit stören, sondern auch Sammel- und Vorratsgefäße,It is with the use of such emulsions in mechanical metalworking a known fact that significant amounts of foam are formed as a result of the inevitable agitation of the emulsion, which not only disrupt the mechanical work, but also collection and storage vessels,
die zur Aufnahme oder Bereithaltung der Emulsion dienen, zum Überlaufen bringen.which serve to take up or keep the emulsion ready to overflow.
Es sind bereits verschiedene Vorschläge gemacht worden, um die Schaumfähigkeit dieser Mineralölemulsionen zu unterdrücken. Eine übliche Methode besteht in der Verwendung einer etwas unstabilen Emulsion, die freies öl enthält. Bis zu einem gewissen Grade wirkt freies öl schaumunterdrückend.Various proposals have already been made with regard to the foaming ability to suppress these mineral oil emulsions. A common method is to use it a somewhat unstable emulsion that contains free oil. Up to a certain Grade free oil has a foam-suppressing effect.
to Diese Arbeitsweise hat aber den Fehler, daß bei längerem Gebrauch diese ,unstabilen Emulsionen die Neigung zeigen, ganz und gar zu zerfallen.To this way of working has the problem that with prolonged use it becomes unstable Emulsions tend to disintegrate completely.
Ein anderer Vorschlag empfahl den Zusatz von Stearinsäure oder Aluminiumstearat zu den wasserlöslichen ölen. Aber auch dieser Weg ist nicht gangbar, weil diese Zusätze mit vorhandenem freiem oder durch Hydrolyse aus den Natriumsulfonaten oder Naphthenaten gebildetem Alkali Seifen bilden, die zur ölbildung oder zum Festwerden der löslichen öle führen, was ganz besonders störend ist.Another suggestion recommended the addition of stearic acid or aluminum stearate to the water-soluble oils. But even this path is not feasible because this Additives with available free or by hydrolysis from sodium sulfonates or Naphthenates formed alkali soaps, which lead to oil formation or to the solidification of the soluble oils, which is particularly troublesome.
Die vorliegende Erfindung offenbart nun einen neuen Weg, die Neigung der wasserlöslichen öle zur Schaumbildung zu unterdrücken. The present invention now discloses a new way, the propensity of the water-soluble to suppress foaming oils.
Es wurde gefunden, daß Wachse von Säuren mit mehr als 22 Kohlenstoffatomen im Molekül, die 5 bis 5o°/o solcher Säuren in freiem Zustand enthalten, die Fähigkeit besitzen, das Schäumen der wasserlöslichen öle zu unterdrücken. Das geeignetste Wachs dieser Art ist das Montanwachs, jedoch sindIt has been found that waxes contain acids with more than 22 carbon atoms in the molecule, the 5 to 50 per cent. of such acids Contained in the free state, have the ability to foam the water-soluble suppress oils. The most suitable wax of this type is the montan wax, however
synthetische wachsartige Produkte, wie CP- und Z-Wachs (vgl. E. J. Fischer »Wachse, wachsähnliiche Stoffe und technische Wachsgemenge« 1934, S. 48 bis 57), ebenso auch Wollwachs für die Erfindung brauchbar. Die Wachse werden den wasserlöslichen ölen in Mengen von 0,001 bis 0,5 Gewichtsprozent zugesetzt. Die Zusatzmenge darf in keinem Fall so groß sein, daß sich das Wachs bei gewöhnlicher Temperatur ausscheidet. Zweckmäßig ist es, das wasserlösliche öl auf die Schmelztemperatur des Wachses zu erhitzen und dann das Wachs durch energisches Rühren darin zu verteilen. Eine Überhitzung des Öles ist zu vermeiden.synthetic waxy products, such as CP and Z wax (cf. E. J. Fischer »Waxes, wax-like substances and technical wax mixtures ”1934, pp. 48 to 57), as well Wool wax useful for the invention. The waxes are made in the water soluble oils Amounts of 0.001 to 0.5 percent by weight are added. The additional amount must not be used in any Fall so large that the wax precipitates at ordinary temperature. Appropriate is to heat the water-soluble oil to the melting temperature of the wax and then to distribute the wax in it by stirring vigorously. Overheating of the Avoid oil.
Diese Wachse unterdrücken besonders wirksam die Schaumbildung bei den wasserlöslichen ölen, bei denen als Emulgens Naphthenate verwendet werden.These waxes are particularly effective in suppressing foam formation in the case of the water-soluble ones oils in which naphthenates are used as emulsifiers.
Es sei darauf hingewiesen, daß diese Wirkung auch nicht gestört wird, wenn dem wasserlöslichen öl noch Farbstoffe, Antioxygene, Verdickerpolymere, Harze oder sonstige für Mineralöle übliche Zusätze gemacht werden. Um den technischen Effekt der Erfindung aufzuzeigen, wurde einerseits ein lösliches öl, das z. B. eine Mischung von Sulfonaten und Naphthenatseife als Emulgens enthielt, mit 40 Teilen Wasser gemischt. Ein anderer Teil des löslichen Öles wird mit etwa 0,01% Montanwachs versetzt und in 40 Teilen Wasser emulgiert. Beide Emulsionen wurden unter Benutzung des Mixmasterschaumschlägers bearbeitet.It should be noted that this effect is not disturbed if the water-soluble oil nor dyes, antioxidants, thickener polymers, or resins other additives customary for mineral oils are made. To the technical effect to show the invention, on the one hand, a soluble oil that z. B. a mixture of Containing sulfonates and naphthenate soap as emulsifiers, mixed with 40 parts of water. A other part of the soluble oil is mixed with about 0.01% montan wax and divided into 40 parts Water emulsified. Both emulsions were made using the Mixmaster whisk processed.

Dem ebenfalls als Schaumunterdrücker vorgeschlagenen Oktylalkohol gegenüber haben die erfindungsgemäß verwendeten Wachse den Vorzug, daß sie nicht flüchtig sind. Der Oktylalkohol gibt bei der Verwendung als Entschäumungsmittel sehr unangenehme Dämpfe ab. Außerdem ist Oktylalkohol wesentlich kostspieliger gegenüber dem Montanwachs, was bei einem derartigen Gemisch selbstverständlich auch von großer Bedeutung ist.Opposite the octyl alcohol, which is also proposed as a foam suppressor the waxes used according to the invention have the advantage that they are non-volatile. Of the Octyl alcohol is very unpleasant when used as a defoaming agent Fume off. In addition, octyl alcohol is much more expensive than montan wax, which is of course also of great importance with such a mixture.
