Description
Zur Herstellung eines wirksamen flüssigen synthetischen Schmiermittels empfiehlt es sich bekanntlich, ein Produkt zu verwenden, das die gewünschten Viskositätseigenschaften besitzt, und zu diesem Produkt eine geringe Menge von geeigneten aktiven Molekülen hinzuzusetzen. Diese polaren Moleküle haften dann vorzugsweise an den Berührungsflächen und bilden eine Haut, in deren Ebene sich die Schmierungsphänomene abspielen. Eine derartige Mischung ge- währleistet also die hydrodynamische Schmierung infolge ihrer Viskosität und besitzt die gewünschte Schlüpfrigkeit, die ihr durch die aktiven Moleküle verliehen ist. Auf diese Weise können zahlreiche Typen von Schmiermitteln hergestellt werden.In order to produce an effective liquid synthetic lubricant, it is well known that to use a product that has the desired viscosity properties and to that product add a small amount of suitable active molecules. These polar molecules adhere then preferably on the contact surfaces and form a skin in the plane of which the lubrication phenomena take place. Such a mixture So it ensures hydrodynamic lubrication due to its viscosity and has the desired one Slipperiness that is given to it by the active molecules. In this way numerous Types of lubricants are made.
In der Reihe der Phosphorsäureester der Phenole hat bisher lediglich das Trikresylphosphat eine technische Verwendung gefunden. Diese Verbindung besitzt wertvolle Eigenschaften, sie hat aber den Nachteil, daß sie eine verhältnismäßig geringe Viskosität aufweist. Die Viskosität dieses Körpers bei 35° ist etwa 30 Centistokes und bei 500 etwa 15 Centistokes. In the series of phosphoric acid esters of phenols, only tricresyl phosphate has so far found industrial use. This compound has valuable properties, but it has the disadvantage that it has a relatively low viscosity. The viscosity of this body at 35 ° is about 30 centistokes at 50 0 about 15 centistokes.
Die Patentinhaberin hat nun gefunden, daß ein anderer Phosphorsäureester, nämlich das Trixylenylphosphat The patent proprietor has now found that another phosphoric acid ester, namely trixylenyl phosphate

Die Viskosität dieses Körpers bei-35° ist nämlich etwa 53 Centist okes und bei 500 etwa 23 Centistokes. The viscosity of this body at -35 ° is namely about 53 centistokes and at 50 0 about 23 centistokes.
Diese Flüssigkeit muß möglichst rein sein, um eine gute Beständigkeit zu gewährleisten. Sie kann jeden geeigneten Zusatz an Schlüpfrigkeitssteigerungsmitteln erhalten. So können ausgezeichnete Mischungen, die zur Schmierung in der Feinmechanik geeignet sind, u. a. folgende Zusammensetzungen besitzen:This liquid must be as pure as possible in order to ensure good stability. She can do anyone obtain suitable addition of lubricity enhancers. So can excellent mixes that are suitable for lubrication in precision mechanics, among others. have the following compositions:

Bei gewissen Anwendungen in der Uhrmacherei zum Beispiel ist es notwendig, daß -ein auf die Reibungsflächen (Zapfen, Spiralschrauben usw.) aufgebrachtes Schmieröl sich nicht ausbreitet und nicht unter Überziehung der Scheiben ausweicht; es muß vielmehr zusammengeballt und konzentriert in Kappen an dein. Punkte verbleiben, wo der Schmiermitteltropfen hin-, gebracht ist. Man weiß jetzt, daß der Grund für die Ausbreitung der Öle darin besteht,, daß die Kohäsion der Ölmoleküle, d. h. also die gegenseitige Anziehung dieser Moleküle, übertroffen wird von der Anziehung dieser Moleküle durch die von den Oberflächen "der Feststoffe (Scheiben, Achsen usw.) bewirkten Kraft*, felder.In certain watchmaking applications, for example, it is necessary that -a is applied to the friction surfaces (tenons, spiral screws, etc.) Lubricating oil does not spread and does not escape by overdrawing the discs; rather it must clustered and concentrated in caps on yours. Points remain where the lubricant drop is brought to. We now know that the reason for that Propagation of the oils consists in the fact that the cohesion of the oil molecules, i. H. so the mutual attraction of these molecules, is surpassed by the attraction of these molecules by that of the surfaces "of the Solids (disks, axles, etc.) caused force *, fields.

Gemäß einem weiteren Merkmal der Erfindung kann man diesen Nachteil beseitigen, indem man in das Trixylenylphosphat eine sehr geringe Menge von besonders aktiven Molekülen, wie die einer Fettsäure, sogar einer ungesättigten Fettsäure, eines Phenols oder eines Alkohols mit langer Kette, einverleibt. Diese Moleküle erhöhen beträchtlich die Kohäsion, und infolgedessen haben die Schmiermitteltropfen nicht mehr die Neigung, sich auf den festen Flächen auszubreiten. Die nachstehend beispielsweise angegebenen Mittel genügen vollständig:According to another feature of the invention this disadvantage can be eliminated by adding a very small amount of to the trixylenyl phosphate particularly active molecules, such as those of a fatty acid, even an unsaturated fatty acid, a phenol or a long chain alcohol. These molecules considerably increase the cohesion, and as a result, the lubricant drops no longer have a tendency to settle on the solid surfaces spread out. The means given below, for example, are fully sufficient:

," Man kann auch gemäß der Erfindung das Trixylenylphosphat in Mischung verwenden, zum Beispiel um die Viskosität des Trikresylphosphats oder eines oder mehrerer, anderer organischer Phosphorsäureester zu erhöhen."One can also use the trixylenyl phosphate according to the invention use in a mixture, for example to adjust the viscosity of the tricresyl phosphate or one or of several other organic phosphoric acid esters.
