Description

  • Schmier- bzw. Poliermittel Bei den zahlreichen Phosphorverbindungen, die zur Verbesserung der Eigenschaften von Schmierstoffen vorgeschlagen wurden, handelt es sich in der Mehrzahl um organische Ester der Säuren des Phosphors. Daneben werden auch Verbindungen mit direkter Phosphor-Kohlenstoff-Bindung erwähnt, von denen man gegenüber den Estern den Vorteil einer festeren Bindung des organischen Restes und damit eine größere Stabilität erwarten konnte. Indes haben auch diese Verbindungen ihre gewissen Mängel aufzuweisen, die sie für viele Anforderungen der Praxis unbrauchbar machen. So z. B. handelt es sich bei den Einwirkungsprodukten von Phosphor, Phosphorhalogeniden oder Phosphorsulfiden auf Olefine, Paraffine, Fette und andere organische Verbindungen keineswegs um genau definierte chemische Verbindungen, sondern um Gemische unbekannter Konstitution, deren Herstellung und .Anwendung mit den bekannten Nachteilen verbunden ist. Soweit es sich hierbei um organische Phosphorchloride handelt, sind der Verwendung solcher Körper wegen der leichten Reaktionsfähigkeit,des Halogens sehr enge Grenzen gesetzt. Organische primäre und sekundäre Phosphorwasserstoffe sind vielfach wegen ihres Geruchs, ihrer Giftigkeit, ihrer Flüchtigkeit usw. ungeeignet, während tertiäre Phosphorwasserstoffe, wie z. B. Triphenylphosphin und sein Oxyd bzw. Sulfid, nur ungenügende Auswirkung besonders auf die Zerreißfähigkeit des Ölfilms haben.
  • Demgegenüber fanden wir, daß sich besonders günstige Wirkungen erzielen lassen, wenn man als Schmier- oder Polier- bzw. als Zusatzschmier- oder -poliermittel Phosphorverbindungen der allgemeinen Formel verwendet: worin R einen Kohlenwasserstoffrest, wie z. B. einen Alkyl-, Aralkyl-, Aryl- oder heterocyclischen Rest, und X eine der folgenden Gruppen: OH, S H, O R, SR, N H2, N H R, N R2 'bedeuten.
  • Die Formeln zeigen im übrigen, daß mindestens eine Valenz des Posphors an den Rest R und mindestens eine an X gebunden sein soll. Die Kohlenwasserstoffreste können in geeigneter Weise substituiert sein.
  • Beispielsweise haben sich bei der Untersuchung die folgenden Verbindungen bewährt: Ihre Anwendung wird für zwei typische Fälle an Hand der folgenden Beispiele erläutert: Beispiel i Einem Motorenöl auf Mineralölgrundlage werden o,5 % der Verbindung 2 zugesetzt. Auf einer Glprüfungsmaschine wird die Belastbarkeit des Ölfilms bis zum Zerreißen geprüft. Während beim nichtpräparierten Öl dasLager bei etwa 35okg/qcm frißt, läßt sich die Belastung beim präparierten Öl auf 1500 bis 2000 kg/qcm steigern. Ein auf die gleiche Weise mit dem als Zusatzmittel empfohlenen Triphenylphosphin versetztes Öl erreicht bereits bei goo bis iooo kg/qcm Belastung seinen Zerreißwert. Solche mit den neuen Verbindungen präparierte öle eignen sich also hervorragend als sogenanntes Hochdruckschmiermittel. Sie erlauben eine weit über das normale Maß hinausgehende Belastung von Lagern, Wellen, Getrieben und anderen Maschinenelementen. Beispiel e Eine Welle aus Werkstahl rotiert unter Zufuhr von Schmieröl, das mit i o/o der Verbindung 3 versetzt ist, zwischen zwei Schleifbacken unter einem Druck von 5oo bis i5oo kg/qcm. Man erzielt auf diese Weise bei gleichzeitigem äußerst geringem Abrieb eine außerordentliche Glättung der Metalloberfläche, wie sie sonst nur durch kostspielige Methoden der Feinschleiftechnik erzielt wird.
