Description
Klarbleibendes oder nur schwach opalisierendes Schmiermittel aus Wollfett und Mineralölen Seit der Einführung der technischen Fabrikation des Neutralwollfettes ist man bemüht, brauchbare Mischungen aus Neutralwollfett mit Mineralölen herzustellen, um die hohe Schmierwirkung des Neutralwollfettes auszunutzen. Neutralwollfett allein schmilzt bekanntlich erst bei 40' C und kann folglich nur an warmen Lagerstellen gebraucht werden, an die es außerdem noch gepreßt werden muß. Abgesehen davon ist das Neutralwollfett in unvermischtem Zustande zu zähe, so daß die innere Reibung im Schmiermittel an den Verbrauchsstellen nachteilig in Erscheinung tritt. Mischt man hingegen Neutralwollfett mit Mineralöl in geeignetem Verhältnis, so verleiht das Neutralwollfett dem Mineralöl die notwendige Fettigkeit,, was besonders bei etwas erhöhten Temperaturen vorteilhaft ist, bei denen die leichteren Mineralöle sehr dünnflüssig und wenig schlüpfrig werden.Lubricant made from wool grease that remains clear or has only slightly opalescent properties and mineral oils Since the introduction of the technical manufacture of neutral wool fat efforts are made to produce usable mixtures of neutral wool fat with mineral oils, to take advantage of the high lubricating effect of the neutral wool grease. Neutral wool fat alone It is known that it only melts at 40 ° C and can therefore only be used at warm storage locations are needed to which it also still has to be pressed. Apart from that is to toughen the neutral wool fat in an unmixed state, so that the internal friction disadvantageously appears in the lubricant at the points of use. Mixes on the other hand, if you add neutral wool fat with mineral oil in a suitable ratio the neutral wool fat the mineral oil the necessary greasiness, which is especially important Somewhat elevated temperatures is beneficial at which the lighter mineral oils very thin and not very slippery.
Nun sind jedoch Mischungen, die durch Zusammenschmelzen von Mineralöl mit Neutralwollfett hergestellt werden, in vielen Fällen nicht haltbar, da Flocken aus dem Neutralwollfett ausscheiden. Man hat bereits versucht, diese Ausscheidungen durch Hinzufügung geringer Mengen von Seifen, insbesondere Magnesiaseifen, zu verhindern. Diese Mischungen scheiden zwar keine Flocken von Wollfett aus, sie gelatinieren aber zu leicht und gehen außerdem nicht durch Dochte hindurch, so daß sie für Dochtschmiergefäße überhaupt nicht verwendbar sind.Now, however, mixtures are created by fusing together mineral oil are made with neutral wool fat, in many cases not durable due to flakes excrete from the neutral wool fat. One has already tried these eliminations prevent by adding small amounts of soaps, especially magnesia soaps. Although these mixtures do not excrete flakes of wool fat, they gelatinize but too light and also do not go through wicks, so that they are suitable for wick lubricators are not usable at all.
Man hat ferner vorgeschlagen, Harzverbindungen, besonders Ester der Harzsäuren, dem Mineralölwollfettgemisch hinzuzufügen. Diese Mischungen bleiben klar, sie enthalten aber entweder freie Harzsäure oder neigen sehr leicht zu deren Bildung, was bei guten Schmiermitteln unzulässig ist.It has also been proposed to use resin compounds, particularly esters of the Resin acids to add to the mineral oil wool fat blend. These mixtures remain clear, but they either contain free resin acid or are very prone to it Education, which is inadmissible with good lubricants.
Durch eingehende Versuche hat sich nun herausgestellt, daß Mischungen von Mineralöl mit Neutralwollfett ständig klarbleiben, wenn gemäß der Erfindung Naphthalin hinzugefügt wird.Thorough experiments have now shown that mixtures of mineral oil with neutral wool fat always remain clear if according to the invention Naphthalene is added.
Der Zusatz von Naphthalin zu Mineralschmierölen ist an sich nicht neu. So erwähnt das Patent 174 249, K1. 23 c, daß es bereits bekannt sei, Ölen zur Erhöhung der Konsistenz Naphthalin hinzuzusetzen. Damit wird erreicht, daß eine feste Schmiermasse nach Art der Schmierbrikette entsteht, die an heißlaufenden Zapfen ihre Form behält. Im vorliegenden Falle handelt es sich um etwas ganz anderes, denn hier soll das Naphthalin nur der Lösungsvermittler für das Neutralwollfett sein, so daß ein homogen bleibendes flüssiges Schmiermittel entsteht, nicht eine feste Schmiermasse. Auch im Patent 516 401 wird der Zusatz von Naphthalin zu Mineralschmierölen erwähnt. Hier handelt es sich aber nicht darum, daß das Naphthalin dauernd im Schmieröl verbleiben soll, sondern das Naphthalin soll nur durch seine Kristallstruktur das Abfiltrieren von paraffinähnlichen Verunreinigungen erleichtern. Das Naphthalin wird also gänzlich aus den Schmierölen wieder entfernt, sogar die letzten Spuren des Naphthalins werden noch durch Abtreiben mit Wasserdampf beseitigt. Im Verfahren- gemäß vorliegender Erfindung wird dagegen jede übermäßige Erhitzung und jede Verwendung von sogenanntem direktem Dämpf streng vermieden, um den Naphthalinzusatz nicht zu vermindern, damit die lösende Kraft des Naphthalins auf das Neutralwollfett voll erhalten bleibt.The addition of naphthalene to mineral lubricating oils is not per se New. For example, the patent 174 249, K1. 23 c that it was already known to use oils Add naphthalene to increase the consistency. This ensures that a Solid lubricating mass is created in the manner of the lubricating briquette, which is attached to overheating pins retains its shape. In the present case it is about something completely different, because here the naphthalene should only be the solubilizer for the neutral wool grease, so that a liquid lubricant that remains homogeneous is created, not a solid one Lubricant. Patent 516 401 also mentions the addition of naphthalene to mineral lubricating oils mentioned. The point here is not that the naphthalene is permanently in the lubricating oil should remain, but the naphthalene should only through its crystal structure that Make it easier to filter off paraffin-like impurities. The naphthalene is therefore completely removed from the lubricating oils, even the last traces of naphthalene will still be eliminated by wiping with steam. In the method of the present invention, on the other hand, any excessive heating will be avoided and strictly avoided any use of so-called direct steam in order to avoid the addition of naphthalene not to diminish, so that the dissolving power of the naphthalene on the neutral wool grease is fully preserved.
Zweckmäßig wird zunächst das Neutralwollfett mit dem Naphthalin verschmolzen und auf etwa 12o ° C erwärmt, um die letzten Spuren Wasser aus dem Neutralwollfett zu beseitigen. Darauf erfolgt der Zusatz des Mineralöls, eine gründliche Durchrührung des ganzen Gemisches und seine Abkühlung. Wenn beim Abkühlen zuweilen ein geringes Opalisieren der Mischung eintritt, so ist dies ohne Bedeutung, da beim weiteren Aufbewahren der Ölmischung eine Flockenbildung von ausgeschiedenem Wollfett nicht zu beobachten ist und das Öl auch niemals wolkig erscheint. Als besonders geeignete Mischung wird beispielsweise angegeben 18 kg Neutralwollfett, 5,5 kg Naphthalin und 76,5 kg Spindelöl.It is advisable to first fuse the neutral wool grease with the naphthalene and heated to about 120 ° C to remove the last traces of water from the neutral wool fat to eliminate. This is followed by the addition of the mineral oil, a thorough stirring of the whole mixture and its cooling. If at times a little when cooling down Opalization of the mixture occurs, so this is of no importance, since further Keeping the oil mixture will not cause flaking of excreted wool fat can be observed and the oil never appears cloudy. As particularly suitable Mixture is given, for example, 18 kg neutral wool fat, 5.5 kg naphthalene and 76.5 kg spindle oil.
Für jeden Verwendungszweck und jedes Mineralöl kann durch Versuche leicht die geeignete Mischung festgestellt werden, da nur darauf geachtet werden muß, daß der Neutralwollfettzusatz den Stockpunkt der Olmischung höher bringt. Es muß also die Temperatur der Verwendungsstelle berücksichtigt werden. Das angegebene Beispiel von 18 kg Neutralwollfett, 5,5 kg Naphthalin und 76,5 kg Spindelöl stellt für ein deutsches Durchschnittsklima die obere Grenze des Neutralwollfettzusatzes dar. Denn in Fabrikationsräumen sinkt die Temperatur auch bei Heizung leicht auf 6 bis 7 ° Wärme, und dann würde eine Ölmischung, die mehr als 18 kg Neutralwollfett enthält, bereits zu konsistent werden und nicht mehr durch enge Schmierkanäle fließen. Naphthalin ist außerdem eine feste Substanz, die starke Neigung zum Kristallisieren hat, auch aus diesem Grunde wird man mit dem Naphthalinzusatz nicht höher gehen, um etwa dadurch noch mehr Neutralwollfett in die Mischung hineinbringen zu können. Man wird vielmehr obige Mengenverhältnisse als die Normalmischung ansehen und bei Verwendung in großer Kälte eine Verdünnung der Normalmischung mit reinem Mineralöl vornehmen.For every purpose and every mineral oil can be tested It is easy to determine the appropriate mix, as only attention is paid to it it must be that the neutral wool fat addition brings the pour point of the oil mixture higher. It so the temperature of the place of use must be taken into account. The specified Example of 18 kg of neutral wool fat, 5.5 kg of naphthalene and 76.5 kg of spindle oil for a German average climate the upper limit of the neutral wool fat addition Because in production rooms the temperature drops slightly even when heated 6 to 7 ° heat, and then an oil mixture that contains more than 18 kg of neutral wool fat already become too consistent and no longer flow through narrow lubrication channels. Naphthalene is also a solid substance that has a strong tendency to crystallize has, also for this reason you will not go higher with the addition of naphthalene, in order to be able to bring even more neutral wool fat into the mixture. Rather, the above proportions will be viewed as the normal mixture and at Use in extreme cold a dilution of the normal mixture with pure mineral oil make.
Bei schweren Mineralmaschinenölen geht man zweckmäßig mit dem Neutralwollfettzusatz etwas herunter, etwa auf 15 -bis 16 kg, so daß die Mischung dann nach folgendem Ansatz zu erfolgen hat: 16 kg Neutralwollfett, 4,9 kg Naphthalin, 79,1 kg Mineralmaschinenöl. Außerdem ist zu beachten, daß Naphthalin einen Flammpunkt von etwa 8o ° C hat. Der Flammpunkt der Olmischungen wird also durch das Naphthalin theoretisch herabgesetzt. Es ist allerdings, dabei von Wichtigkeit, daß der Naphthalinzusatz nur gering ist, daß ferner das Naphthalin durch das Wollfett bei der Dampfbildung gebunden wird und daß endlich das Neutralwollfett mit seinem Flammpunkt von etwa 250' C sehr vorteilhaft auf den Flammpunkt der Mischung einwirkt. Die naphthalinhaltigen Olmischungen sind also trotz des etwas erniedrigten Flammpunktes vorteilhaft zu verwenden, zumal Naphthalin billig und in ausreichenden Mengen vorhanden ist.For heavy mineral machine oils it is useful to the neutral wool fat additional bit run, about 15 - up to 16 kg, so that the mixture then has to be made according to the following approach: 16 kg Neutral wool fat, 4.9 kg of naphthalene, 79.1 kg mineral machine oil. It should also be noted that naphthalene has a flash point of around 80 ° C. The flash point of the oil mixtures is therefore theoretically reduced by the naphthalene. It is, however, important that the addition of naphthalene is only small, that the naphthalene is bound by the wool fat during steam formation and that finally the neutral wool fat with its flash point of about 250 ° C has a very beneficial effect on the flash point of the mixture. The naphthalene-containing oil mixtures can therefore be used advantageously in spite of the somewhat lowered flash point, especially since naphthalene is cheap and available in sufficient quantities.
