Description
Schmierfette Gegenstand des Pratentes 942 526 ist die Zusammensetzung von Schmierfetten auf der Basis von mineralischen oder synthetischen Schmierölen mit einem Gehalt an 5 bis q.o Gewichtsprozent Natronseifen gesättigter Fettsäuren, mit 12 bis 24 Kohlenstoffatomen als Dickungsmittel und wasserfreiem Trinatriumphosphat.Lubricating greases The subject of patent 942 526 is the composition of lubricating greases based on mineral or synthetic lubricating oils with a content of 5 to q.o weight percent sodium soaps of saturated fatty acids, with 12 to 24 carbon atoms as a thickener and anhydrous trisodium phosphate.
Gemäß vorliegender Erfindung enthalten Schmierfette Trinatriumphosphat in Form eines Komplex; salzes mit den Natriumseifen der gesättigten Fettsäuren mit i2 bis 24 Kohlenstoffatomen.In accordance with the present invention, lubricating greases contain trisodium phosphate in the form of a complex; salt with the sodium soaps of saturated fatty acids with i2 to 24 carbon atoms.
Die erfindungsgemäßen Schmierfette bleiben bei hohen Temperaturen und sehr hohen Schergeschwindigkeiten stabil und sind insbesondere zum Schmieren von Wälzlagern, wie Kugel- und Rollenlager, geeignet.The lubricating greases of the invention remain at high temperatures and very high shear rates are stable and are particularly useful for lubrication of roller bearings, such as ball and roller bearings.
Das Schmierfett wird dadurch hergestellt, daß man ein geeignetes fettes Öl, vorteilhaft Rüböl, oder Gemische von Fettsäuren und Glycerin usw. bei mäßiger Temperatur in Gegenwart nur eines Teils des als Grundlage verwendeten Schmieröls verseift. Danach wird das verseifte Gemisch auf etwa 2q.6 bis 3o2° erhitzt, damit das bei der Verseifung frei gewordene Glycerin mit dem Verseifungsmittel reagiert. Das Glycerin wird offensichtlich in Aerolein umgewandelt, welches seinerseits einer weiteren Reaktion unterliegt, die zu einem Sa.lzproduktvon niedrigem Molekulargewicht führt. Der genaue Mechanismus dieser Reaktion ist nicht bekannt. Man kann annehmen, daß das Glycerin dehydratisiert wird und das dadurch entstehende Aerolein oder ein Dimer desselben mit dem überschüssigen Alkali reagiert. Man verwendet das Verseifungsmittel, insbesondere NaOH, im Ilberschuß über die Menge, die zur Verseifung des Fettes oder der Fettsäure und zur Reaktion mit dem Glycerin oder dessen Zerfallsprodukten notwendig ist. Dieser Alkaliüberschuß wird mit der Säure des Phosphors bei hoher Temperatur, zumindest 2i8, vorteilhaft oberhalb 232°. in Reaktion gebracht.The grease is made by having a suitable grease Oil, preferably rapeseed oil, or mixtures of fatty acids and glycerine etc. with moderate Temperature in the presence of only part of the base lubricating oil saponified. Then the saponified mixture is heated to about 2q.6 to 3o2 ° with it the glycerine released during the saponification reacts with the saponifying agent. The glycerin is apparently converted into aerolein, which in turn one undergoes further reaction resulting in a low molecular weight salt product leads. The exact mechanism of this reaction is not known. One can assume that the glycerin is dehydrated and the resulting aerolein or a Dimer of the same reacts with the excess alkali. The saponifying agent is used in particular NaOH, in excess of the amount required to saponify the fat or the fatty acid and to react with the glycerine or its decomposition products is. This excess alkali is combined with the acid of phosphorus at high temperature, at least 2i8, advantageously above 232 °. brought into reaction.
In dieser Weise wird das Phosphorsalz derart in die Seife eingeführt, daB sich in dem fertigen Fett keine Salzkristalle finden, selbst wenn man ein Mikroskop von hohem Auflösungsvermögen verwendet. Es ist anzunehmen, da.ß bei dieser Arbeitsweise ein Komplex von Salz und Seife gebildet wird, welches das Phosphat einschließt, aber in jedem Falle sind keine Salzkristalle feststellhar. Das Produkt ist wesentlich von dem unterschieden, welches man gemäß Hauptpatent durch einfachen Zusatz von Trinatriurnphosphat zum Fett erhält. Gewöhnlich wird zunächst ein Fett mit einem verhältnismäßig hohen. Seifengehalt hergestellt. Es kumn dann anschließend mit Öl verschnitten werden, indem man Schmieröl in Mengen 'von 75 bis i250/0 zusetzt. Darauf wird das mit Öl verschnittene Produkt gegen eine Ausscheidung von Öl und mechanische Zersetzung im Einsatz stabilisiert, indem man es in einem mechanischen Bearbeiter, einer Homogenisiermaschine oder Mahlvorrichtung Scherspannungsfeldern hoher Geschwindigkeit aussetzt.In this way the phosphorus salt is introduced into the soap in such a way that that there are no salt crystals in the finished fat, even with a microscope of high resolution used. It can be assumed that in this way of working a complex of salt and soap is formed, which includes the phosphate, but in any case no salt crystals are found. The product is essential differed from that which one can get according to the main patent by simply adding Trinatrium phosphate is added to the fat. Usually a fat starts with one relatively high. Soap content made. It is then followed by oil can be blended by adding lubricating oil in quantities from 75 to i250 / 0. Thereon the product blended with oil is against an excretion of oil and mechanical Decomposition stabilized in use by having it in a mechanical processor, a homogenizer or grinder high-speed shear stress fields suspends.
Ein derart homogenisiertes Fett braucht nur 6 % Seife zu enthalten. Gewöhnlich werden Mineralöle bevorzugt, aber auch synthetische Ester, Polyglykole und andere bekannte synthetische Öle sind geeignet.Such a homogenized fat only needs to contain 6% soap. Mineral oils are usually preferred, but synthetic esters, polyglycols, are also preferred and other known synthetic oils are suitable.
Für das Herstellungsverfahren des Komplexsalzes wird in vorliegendem Patent kein. Schutz beansprucht. Das erfindungsgemäße Produkt besteht bevorzugt n.us etwa 65 bis 85 % Schmieröl, vorteilhaft Mineralschmieröl, der Seifengehalt des Fettes liegt zwischen io und 35 Gewichtsprozent und der Phosphatgehalt zwischen etwa o,5 bis 30/0. Man kann außerdem die üblichen Zusätze verwenden, z. B. o,25 biss 2% Phenylnaphthylamin als Antibxydationsmittel, und ähnliche Mengen eines öllöslichen Sulfonates, um dem Schmierfett eine weitere Rostschutzwirkung zu verleihen, wenn dies von besonderer Bedeutung ist. Für ein optimales Verhalten in Gegenwart verschiedener Nichteisenmetalle kann man o, i bis i % eines guten Metalldesaktivators zusetzen, z. B. Di-salicylalpropylendiamin.For the production process of the complex salt is in the present Patent no. Protection claimed. The product of the invention is preferred n.us about 65 to 85% lubricating oil, advantageously mineral lubricating oil, the soap content of the fat is between 10 and 35 percent by weight and the phosphate content between about 0.5 to 30/0. You can also use the usual additives such. B. o, 25 up to 2% phenylnaphthylamine as an anti-oxidant, and similar amounts of an oil-soluble one Sulfonates to give the grease a further anti-rust effect, if this is of particular importance. For optimal behavior in the presence of different people Non-ferrous metals can be added o, i to i% of a good metal deactivator, z. B. Di-salicylalpropylenediamine.
