1H Die Erfindung bezieht sich auf schwer entflammbare Flüssigkeiten, welche auf Phosphorsäuretrtarylestern basieren. Die Erfindung bezieht sich insbesondere auf eine schwer entflammbare Flüssigkeit, die auf Phosphorsäuretrialyrlestern basiert und einen Hydrolyseinhibitor enthält. 1 H The invention relates to flame-retardant liquids based on phosphoric acid trtaryl esters. The invention relates in particular to a flame-retardant liquid which is based on phosphoric acid trialyrlesters and which contains a hydrolysis inhibitor.
Hydraulikflüssigkeiten auf der Basis von Phosphorsäureestern werden seit einiger Zelt verwendet. Sie haben hierfür geeignete Eigenschaften, insbesondere sind sie schwer entflammbar, so daß sie vor allem In Systemen :> mit geschlossenen Hydraulikkreisläufen verwendet werden, beispielsweise In Hydrauliksystemen von Turbinen und von Druckguß-, Strangguß- und Pressenanlagen. Der Einsatz von derartigen Flüssigkeiten wird beispielsweise in den US-PS 34 68 802 und US-PS 37 23 315 beschrieben.Hydraulic fluids based on phosphoric acid esters have been used for some time. They have properties suitable for this purpose, in particular they are flame-retardant, so that they are mainly used in systems :> be used with closed hydraulic circuits, for example in hydraulic systems of turbines and of die-casting, continuous casting and press systems. The use of such liquids is described, for example, in US Pat. No. 3,468,802 and US Pat. No. 3,723,315.
Obgleich derartige Flüssigkeiten schwer entflammbar und auch thermisch relativ stabil sind, können sie in bestimmten Anwendungsfällen gegenüber Hydrolyse unzureichend widerstandsfähig sein.Although such liquids are flame-retardant and also relatively thermally stable, they can be used in be insufficiently resistant to hydrolysis in certain applications.
;.ii Der Erfindung Hegt nun die Aufgabe zugrunde, eine schwer entflammbare Flüssigkeit zu entwickeln, die gegenüber bekannten in Hydrauliksystemen verwendeten Flüssigkelten verbesserte Eigenschaften aufweist, und zwar insbesondere Im Hinblick auf die Hydrolysestabilität.; .ii The invention is based on the object of developing a flame-retardant liquid that has improved properties compared to known liquids used in hydraulic systems, and in particular with regard to hydrolytic stability.
oder einem Gemisch von Phosphorsäuretriarylestern basiert und gekennzeichnet 1st durch Carbodiimide,or a mixture of phosphoric acid triaryl esters and is characterized by carbodiimides,
is vorzugsweise 0,001 bis 0,5% eines Carbodiimides, Insbesondere Ν,Ν'-Dlcylohexylcarbodilmid, Ν,Ν'-Dllsopropylis preferably 0.001 to 0.5% of a carbodiimide, in particular Ν, Ν'-Dlcylohexylcarbodilmid, Ν, Ν'-Isopropyl carbodlimid, oder N,N'-Bis(4-nltrophenyl)-Carbodilmld, als Hydrolyseinhibitor und durch andere Additivecarbodlimid, or N, N'-bis (4-nltrophenyl) -carbodilmld, as a hydrolysis inhibitor and by other additives (Antioxidantien, Schauminhibitoren, Korrosionsinhibitoren, weitere Hydrolyseinhibitoren u. dgl.).(Antioxidants, foam inhibitors, corrosion inhibitors, further hydrolysis inhibitors and the like).
Die Hydrolysestabilltat eines Produktes auf der Basis von Phosphorsäuretriarylestern wird zunächst durch die chemische Struktur sowie durch die Herstellungsbedingungen und die Reinigung und Behandlung der Grund-4Ii flüssigkeit beeinflußt. Es zeigt sich, daß die Hydrolysestabllltät von Produkten auf der Basis von Phorphorsäuretriarylestern durch Zusatz eines Carbodiimides ganz erheblich verbessert werden kann.The hydrolysis stability of a product based on phosphoric acid triaryl esters is initially determined by the chemical structure as well as by the manufacturing conditions and the cleaning and treatment of the basic liquid. It turns out that the hydrolysis stability of products based on phosphoric acid triaryl esters can be improved quite considerably by adding a carbodiimide.
Die hinsichtlich der Hydrolysestabilität Im BBC-Hydrolysetest (BBC ZLC 2-5-40) erzielten Verbesserungen sind in der Tabelle zusammengefaßt.The improvements achieved in terms of hydrolytic stability in the BBC hydrolysis test (BBC ZLC 2-5-40) are summarized in the table.
Die Hydrolyse von Phosphorsäureestern wird durch Spuren saurer Produkte, insbesondere durch saure Phosphorsäurepartlalester (sekundäre Phosphorsäureester), beschleunigt.The hydrolysis of phosphoric acid esters is accelerated by traces of acidic products, in particular by acidic phosphoric acid partial esters (secondary phosphoric acid esters).
Carbodiimide reagieren mit diesen sauren Phosphorsäurepartlalestern zu Harnstoffderivaten und neutralen höhermolekularen Phosphorsäureestern und entfernen sie damit aus der Flüssigkeit. Carbodiimide unterdrücken so außerordentlich wirksam die Hydrolyse.Carbodiimides react with these acidic phosphoric acid partal esters to form urea derivatives and neutral ones higher molecular weight phosphoric acid esters and remove them from the liquid. Suppress carbodiimides so extraordinarily effective is hydrolysis.
Niedrigviskose Phosphorsäuretriarylester zeigen (wegen des unvermeidlich höheren Gehaltes an Triphenyl-5(i phosphorsäureester und ähnliche Verbindungen mit nicht substituierter Phenylgruppe) eine schlechte Hydrolysestabllltät. Bisher waren z. B. keine synthetischen Phosphorsäureester der Viskositätsklasse ISO VG 22 verfügbar, die der BBC-Spezlfikatlon hinsichtlich der Hydrolysestabllltät (NZ-Anstleg Im Test mit vorheriger Erdebehandlung max. 0,20 mg KOH/g) genügten. Durch die Verwendung von Carbodlimlden können auch niedrigviskose Phosphorsäureester den BBC-Hydrolysetest ohne Schwierigkelten bestehen.Low-viscosity phosphoric acid triaryl esters show poor hydrolysis stability (because of the inevitable higher content of triphenyl-5 (phosphoric acid ester and similar compounds with unsubstituted phenyl group). So far, for example, no synthetic phosphoric acid esters of viscosity class ISO VG 22 have been available, which the BBC speclfikatlon with regard to the hydrolysis stability (NZ-Anstleg in the test with previous soil treatment max. 0.20 mg KOH / g) was sufficient. By using Carbodlimlden you can also get low-viscosity Phosphoric acid esters pass the BBC hydrolysis test without difficulty.
Darüber hinaus führt die Inhibierung mit Carbodiimiden auch bei höherviskosen Phosphorsäureestern zu einer deutlich besseren Hydrolysestabllltät.In addition, the inhibition with carbodiimides also leads to higher viscosity phosphoric acid esters a significantly better hydrolysis stability.
Die Versuchsergebnisse zeigen, daß die geprüften aliphatischen bzw. cydoallphatlschen Carbodiimide wesentlich wirksamer als das untersuchte aromatische Carbodlimld sind.The test results show that the tested aliphatic or cydoallphatic carbodiimides are significantly more effective than the aromatic carbodiimides tested.
