Description
Die vorliegende Erfindung betrifft neue funktioneile Flüssigkeiten sowie deren Verwendung.
Der Begriff "funktioneile Flüssigkeiten" oder "Maschinenflüssigkeit" (functional fluid) fasst
Flüssigkeiten zusammen, welche die für das einwandfreie Funktionieren von Maschinen oder Apparaten notwendigen Gebrauchseigenschaften
besitzen. Unter diesen Begriff fallen z.B. Schmiermittel, hydraulische Flüssigkeiten, Dämpf-
und Bremsflüssigkeiten, Dielektrika und Wärmeübertragungsmittel (vgLRoger E. Hatton, INTRODUCTION TO HYDRAULIC
FLUIDS, Reinhold Publishing Corp. New York, 1962, Seite 5).
An funktionelle Flüssigkeiten, die in modernen, bei sehr hohen Temperaturen arbeitenden Maschinen und Apparaturen
verwendet werden, z.B. in Gasturbinen von Flugzeugmotoren, werden sehr hohe Anforderungen gestellt, z.B.:
1. Sie müssen bei den Anwendungsbedingungen flüssig sein und die Fähigkeit haben, auf den verschiedensten
Materialien, insbesondere Metallen, Schmierfilme zu bilden.
2. Sie müssen gegen hohe Temperaturen und oxydative EinflUsse weitgehend beständig sein. ■
3. Sie sollen nicht korrodierend wirken und vor allem keine sauren Zersetzungsprodukte bilden.
4. Sie sollen ihre Schmiereigenschaften über einen möglichst
grossen Temperaturbereich beibehalten, d.h. ihre Viskosität soll von der Temperatur möglichst wenig abhängig
sein. 009886/1696 BAD ORIGfNAU
5. Sie sollen einen möglichst tiefen Erstarrungspunkt
und andererseits einen möglichst hohen Siedepunkt haben.

Es bereitet beträchtliche Schwierigkeiten, funktio-
nelle Flüssigkeiten zu finden, die alle oben genannten
Bedingungen weitgehend erfüllen.
Bisher wurden als hochsiedende funktioneile Flüssigkeiten u.a. Polyphenyläther und Polyalkyl-melamine verwendet.
Die Viskosität dieser Verbindungen ist für manche Zwecke jedoch zu hoch, besonders bei niedrigen.Temperaturen.
Es wurde nun eine hochwertige funktionelle Flüssigkeit mit verhältnismässig niedriger Viskosität gefunden. Sie besteht
aus einem Gemisch von
a) unterhalb 750C und vorzugsweise unterhalb 350C
schmelzenden Polyalkylamino-di- und/oder -triazinen und
b) Polyphenyläthern im Gewichtsverhältnis von 1:9 bis
9:1, vorteilhaft 3:7 bis 7:3.
Die erfindungsgemässen Gemische sind bedeutend weniger viskos als die normalerweise aus den Viskositäten der ihnen
zugrunde liegenden Einzelkomponenten erwarteten Mittelwerte.

kommen vor allem solche der Formel I in Betracht.

Mit Vorteil bedeuten R1, R2, R3, R4, R5 und R6 je
einen n-Alkylrest. X stellt vorzugsweise Stickstoff dar; d.h.
es handelt sich um Polyalkylamino-1,3,5-triazine. Diese Verbindungen
sind in der französischen Patentschrift Nr. 1.328.168 beschrieben. Sie sind beispielsweise durch stufenweise Umsetzung
der 3 Chloratome des Cyanurchlorids mit den gewünschten Alkylaminen nach an sich bekannten Methoden erhältlich.
Beispiele für derartige Polyalkylamino-1,3,5-triazine sind:
2-Dimethylamino-4,6-bis-dibutylamino-l,3,5-triazin,
2rDiäthylamino-4,6-bis-dibutylamino-l,3,5-triazin,

oder -didodecylamino)-1,3,5-triazin, 2-Dimethylamino-4,6-bis-(N-methyl-N-butylatnino)-l,3,5-triazin.
Polyalkylamino-verbindungen der Formel I, in der X

2,4,6-Trichlorpyrimidins mit" den gewünschten Alkylaminen nach an sich bekannten Methoden.
Beispiele solcher Polyalkylamino-pyrimidine sind: 2-Diäthylamino-4,6-bis-dibutylamino-pyrimid:L;j oder
2,4,6-Tris-dibutylamino-pyrimidin.
Selbstverständlich lassen sich als Komponente a) in den erfindungsgemässen Gemischen auch Mischungen von
Polyalkylamino-di- bzw. -triazinen der Formel I verwenden.
Polyphenyläther, die als Komponente b) in den erfindungsgemässen
Gemischen geeignet sind, sind insbesondere solche der Formel II.
(II)
Darin bedeutet η 1 bis 4, vorzugsweise 2 bis 3. Die Phenylringe
können Alkyl- oder Alkoxygruppen mit vorzugsweise 1 bis 20 Kohlenstoffatomen enthalten; vorteilhaft sind sie jedoch
unsubstituiert.
Verbindungen, in denen die Sauerstoffbrücken in m-Stellung
zu einander stehen, und vor allem Gemische von isomeren Polyphenyläthern mit einem hohen Gehalt an Komponenten mit
009886/1696 BAiD
m-ständigen AetherverknUpfungen sind besonders als Komponenten b) geeignet, weil die diese enthaltenden erfindungsgemässen
Gemische besonders' niedrige Erstarrungsbereiche aufweisen. Beispiele solcher Polyphenyläther sind
in der französichen Patentschrift 1.394.304 auf Seite 2 aufgeführt. Ihre Herstellung ist beispielsweise in R.C.
Gunderson und A.W. Hart "Synthetic Lubricants", The Dow Chemical Company, Midland Michigan Ed. Reinhold Publishing
Corp. London, und R. L. Hatton, "Hydraulic Fluids" S. 297-308 (gleicher Verlag) beschrieben.
Die vorstehend erwähnte unerwartete Erniedrigung der Viskosi-
besondere
tat wird ins/bei ganz bestimmten Viskositätsverhältnissen der beiden Mischungskomponenten der Formeln I und II zueinander erhalten. In der Regel muss der Quotient der Logarithmen der je um 0,6 vergrösserten, in Centistokes gemessenen Viskositäten der beiden Komponenten 0,7 bis 1,4 betragen. Dann erhält man Viskositäten der erfindungsgemässen Gemische, die um 20$ und mehr unter den erwarteten arithmetischen Viskositäts-Mittelwerten und gewöhnlich sogar um 5-10$ oder mehr unter dem Wert der Komponente mit niedrigerer Viskosität liegen.

Die neuen funktionellen Flüssigkeiten sind wenig flüchtige OeIe. Sie sind gut thermostabil und bilden bei hohen Temperaturen,
wie sie für Gasturbinenöle für Flugzeugmotoren vorgeschrieben sindj
keine nennenswerten Mengen an sauren Zersetzungsprodukten. Deshalb besitzen sie bei der praktischen Verwendung keine oder nur
sehr geringfügige korrosive ,Wirkung. Zudem quellen sie Kunststoffe,
wie sie beispielsweise für Dichtungen verwendet werden, nur geringfügig. Sie können in einem weiten Temperatür-
009886/1696 BAD ORIGINAL
bereich angewendet werden, haben einen guten Schmiereffekt, einen tiefen Stockpunkt und sind gut säure- und alkalibeständig.
Die erfindungsgemässen funktionellen Flüssigkeiten können als Mehrzweckschmiermittel verwendet werden.
Die neuen funktionellen Flüssigkeiten eignen sich zum Schmieren harter Oberflächen, weil sie darauf festhaftende
Filme bilden. Beispielsweise zeigen sie gute Schmierwirkung für Metalle, Silikate, wie Gläser sowie für andere
schmierbedürftige Materialien, wie organische und anorganische hochpolymere Verbindungen.
Die erfindungsgemässen funktionellen Flüssigkeiten können
für sich allein oder mit Zusätzen verwendet werden. Um ihre Hitzestabilität oberhalb 15O0C noch zu erhöhen, kann man
ihnen Antioxydantien beimischen, wodurch ihre Lebensdauer auch bei erhöhter oxydativer Belastung befriedigend wird.
Als solche Antioxydantien kommen übliche homo- oder heterocyclische aromatische Amine, Hydroxyaryl- und Aminohydroxyarylverbindungen
sowie heterocyclische Verbindungen ohne freie Aminogruppen in Frage, vorzugsweise in Mengen
von 0,01 - 5 Gew.%. (Diese und nachfolgende Prozentarigaben
betreffend Zusätze zu den erfindungsgemässen Gemischen beziehen sich stets auf das Gesamtgewicht der Letzteren).
Beispiele hierfür sind Diphenylamin, kernalkylierte Diphenylamine, Phenylnaphthylamine, Phenylacenaphthenylamine,

N,N1-Diphenyl-p-phenylendiamin, N,N1-Dioctyl-p-phenylendiamin,
