Description
Syntetisk smøreoljesammensetning. Synthetic lubricating oil composition.
Foreliggende oppfinnelse angår syntetiske smøreoljesammen-setninger som brukes i gassturbin- eller jetmotorer. Gassturbinmotorer utsetter- smøremidlet for ekstreme forhold og det dannes indre motortemperaturer på 205-260°C eller høyere. Dette miljø angriper smøreoljen sterkt, slik at de mest avanserte smøreoljesammensetninger på mineraloljebasis ikke kan brukes til gassturbinmotorer. The present invention relates to synthetic lubricating oil compositions used in gas turbine or jet engines. Gas turbine engines expose the lubricant to extreme conditions and internal engine temperatures of 205-260°C or higher are formed. This environment strongly attacks the lubricating oil, so that the most advanced lubricating oil compositions on a mineral oil basis cannot be used for gas turbine engines.
I det siste har man med hell anvendt smøreoljeblandinger Recently, lubricating oil mixtures have been used with success
på basis av syntetiske estere, inneholdende en omhyggelig avpasset blanding av additiver, for smøring av gassturbinmotorer. Disse oljer på esterbasis er' virksomme innenfor et bredt temperaturområde og oppviser høy varmestabilitet, slitasjebestandighet, bæreevne og antioksydasjons-egenskaper samtidig som blandingen gir god smøring. on the basis of synthetic esters, containing a carefully adjusted mixture of additives, for the lubrication of gas turbine engines. These ester-based oils are effective within a wide temperature range and exhibit high thermal stability, wear resistance, load-bearing capacity and antioxidant properties, while the mixture provides good lubrication.
Med utviklingen av nyere og kraftigere gassturbinmotorer With the development of newer and more powerful gas turbine engines
som tas i bruk innen overlydsflyvning, stilles større krav med hensyn til temperaturbelastning og oksydasjonsbelastning av smøreoljen. which are used in supersonic flight, greater demands are made with regard to temperature stress and oxidation stress of the lubricating oil.
Ifølge foreliggende oppfinnelse er tilveiebragt en According to the present invention, a
syntetisk smøreoljesammensetning inneholdende en hoveddel olje på synthetic lubricating oil composition containing a major part of oil
basis av alifatisk ester med smørende egenskaper, fremstilt ved omsetning av pentaerytritol eller en polypentaerytritol eller trimetylolpropan og en organisk monokarboksylsyre med fra ca. 2 til 18 karbo-atomer pr. molekyl, samt et dialkyldifenylamin, en polyhydroksyantrachinon og et trihydrokarbylfosfat, kjennetegnet ved at den inneholder base of aliphatic ester with lubricating properties, produced by reacting pentaerythritol or a polypentaerythritol or trimethylolpropane and an organic monocarboxylic acid with from approx. 2 to 18 carbon atoms per molecule, as well as a dialkyldiphenylamine, a polyhydroxyanthraquinone and a trihydrocarbyl phosphate, characterized in that it contains
a) fra 0,3 til 5 vektprosent av sammensetningen av et a) from 0.3 to 5 percent by weight of the composition of a
alkyl- eller alkaryl-fenylnaftylamin, hvor alkyl- og alkarylradikalet alkyl- or alkaryl-phenylnaphthylamine, where the alkyl and alkaryl radical
har fra 4 til 12 karboatomer, has from 4 to 12 carbon atoms,
b) fra 0,3 til 5 prosent av nevnte dialkyldifenylamin, b) from 0.3 to 5 percent of said dialkyldiphenylamine,
c) fra 0,001 til 1 prosent av nevnte polyhydroksyantrachinon, og d) fra. 0,25 til 10 prosent av nevnte trihydrokarbylfosfat. c) from 0.001 to 1 percent of said polyhydroxyanthraquinone, and d) from. 0.25 to 10 percent of said trihydrocarbyl phosphate.
Smøreoljesammensetningen ifølge oppfinnelsen gir vesent- The lubricating oil composition according to the invention provides essentially
lige forbedringer i avleiringsmengden, korrosjonsbeskyttelse av rustfritt stål og har fremragende temperatur- og oksydasjonsstabilitet. Disse gode egenskaper blir oppnådd ved en kritisk avbalansert og sammensatt smøreoljeblanding på basis av syntetisk ester. Resultatene var overraskende og uventet fordi de er like gode eller bedre enn egenskapene til en fremragende kjent smøreoljesammensetning på syntetisk esterbasis og ble oppnådd med en oljesammensetning som var avgjørende og kritisk modifisert med hensyn til at blandingen ikke inneholdt et additiv som er betraktet som nødvendig for fremstilling av en kommersielt kjent syntetisk smøreolje, nemlig en smøre-olje som er beskrevet i britisk patent nr. 1.020.526. Det additiv det her menes er et ekvimolekylart salt av 1-salicylalaminoguanidin og en alifatisk karboksylsyre. En vesentlig forskjell ved sammensetningen i nevnte patent og den i foreliggende oppfinnelse, er at det anvendes forskjellige antioksydasjonsmidler hvilket resulterer i forskjellige egenskaper. Således benyttes det i det britiske patent usubstituert fenylnaftylamin, mens det i foreliggende sammensetning anvendes et alkyl- eller alkyl-substituert fenylnaftylamin. Forsøk viser at blant annet bruken av slike forskjellige antioksydasjonsmidler resulterer i at man ved anvendelse av foreliggende sammensetning får en vesentlig lavere grad av avleiring og en større viskositets- equal improvements in the amount of scale, corrosion protection of stainless steel and has excellent temperature and oxidation stability. These good properties are achieved by a critically balanced and complex lubricating oil mixture based on synthetic ester. The results were surprising and unexpected because they are as good as or better than the properties of an outstanding known synthetic ester base lubricating oil composition and were obtained with an oil composition that was crucially and critically modified in that the composition did not contain an additive considered necessary for manufacture of a commercially known synthetic lubricating oil, namely a lubricating oil described in British Patent No. 1,020,526. The additive referred to here is an equimolecular salt of 1-salicylalaminoguanidine and an aliphatic carboxylic acid. A significant difference in the composition in the said patent and that in the present invention is that different antioxidants are used, which results in different properties. Thus, unsubstituted phenylnaphthylamine is used in the British patent, while in the present composition an alkyl- or alkyl-substituted phenylnaphthylamine is used. Experiments show that, among other things, the use of such different antioxidants results in a substantially lower degree of deposition and a greater viscosity-

Apparaturen skylles med en oljeladning i 10 minutter og påfylles frisk olje ved oppfylling av det graderte reservoir til 100 ml merket. Oljenivået i avleiringskaret reguleres til det står omkring 1,25 cm over bunnen i glasset. The apparatus is rinsed with an oil charge for 10 minutes and topped up with fresh oil by filling the graduated reservoir to the 100 ml mark. The oil level in the deposit vessel is regulated until it is about 1.25 cm above the bottom of the glass.
Fremgangsmåten ved forsoket er som folger: The procedure for the trial is as follows:
Man slår på avleiringsvarmeroret og innstiller regula-toren på 149°C (300°F). Man holder temperaturen i 5 minutter og innstiller på 204°C (400°F). Man fortsetter til en temperatur på 316°C (600°F) er nådd. Etterhvert som forsoksoljen oppvarmes og utvides, tappes det av olje slik at man holder et nivå 63 mm over bunnen i avleiringsglasset. Man holder likevekts-temperaturforhold ved hjelp av ovnstemperaturen og riktig oljenivå, som dekker avleiringsrbret som omtalt ovenfor. Etterhvert som fordampning finner' sted tilsettes ny olje fra beholderen fo'r å holde riktig nivå. Etter 6 timers kjbring slås avleiringsvarmeren av, man slår på vannkjoler og lar utgående oljetemperatur synke til 122°C. Man slår av alle brytere og luft- og vanntilfbrsler. The deposition heater is switched on and the regulator is set to 149°C (300°F). The temperature is maintained for 5 minutes and set to 204°C (400°F). This is continued until a temperature of 316°C (600°F) is reached. As the pilot oil heats up and expands, the oil is drained so that a level of 63 mm above the bottom of the deposit glass is maintained. Equilibrium temperature conditions are maintained by means of the oven temperature and the correct oil level, which covers the deposit surface as discussed above. As evaporation takes place, new oil is added from the container to maintain the correct level. After 6 hours of heating, the deposit heater is switched off, water jets are switched on and the outgoing oil temperature is allowed to drop to 122°C. All switches and air and water supply valves are switched off.
Etter ca. 18 timers avbrutt prove, gjenopptas forsoket After approx. 18 hours of interrupted test, the attempt is resumed
på samme måten som for opprinnelig start og man fortsetter prbven under standardforhold som angitt i nye seks timer. (Man vil even-tuelt tilsette 5 til 10 ml ny olje til den brukte oljen for å bringe oljenivået opp til 1,25 cm over bunnen av avleiringsglasset). Etter avsluttet oppvarming slås varmeroret av, oljen kjoles og luftstrømmen stanses. Den brukte olje tappes av og avleiringsrbret tas ut fra beholderen. Avleiringsrbret senkes i n-pentan til alle synlige spor av olje er fjernet og blir deretter luft-tbrket. in the same way as for the original start and the test is continued under standard conditions as indicated for another six hours. (You may want to add 5 to 10 ml of new oil to the used oil to bring the oil level up to 1.25 cm above the bottom of the deposit glass). After the heating is finished, the heater is switched off, the oil is cooled and the air flow is stopped. The used oil is drained off and the sediment board is removed from the container. The sediment board is immersed in n-pentane until all visible traces of oil have been removed and is then air-dried.
Avleiringsrbret betraktes på forsiden som vendte inn The deposit rib is considered on the front as facing inwards
mot luftinnlbpet i avleiringsbeholderen. For å bedbmme avleiring-ene anbringes en sjablong med 1/2" graderinger over disse områder med 1 l/2" linjen anbragt på kontaktflaten damp/olje. Hvert halv^ toms segment bedbmmes numerisk med henblikk på type og tykkelse avleiring på dette område. Hvis avleiringenes bedbmmelseskarak-ter varierer innenfor et segment, brukes det hbyeste tall. Man knytter en vektfaktor til hvert av de tre, hovedområder for å få against the air inlet in the deposit container. To measure the deposits, a stencil with 1/2" graduations is placed over these areas with the 1 l/2" line placed on the steam/oil contact surface. Each half-inch segment is measured numerically with regard to the type and thickness of the deposit in this area. If the sediments' grading characteristics vary within a segment, the highest number is used. A weighting factor is attached to each of the three main areas to obtain
me(d forskjeller i deres relative betydning. Den samlede avleiringskarakter fåes ved å legge sammen karakterene for hovedområdene og multiplisere med vektfaktoren. Summen av tre områdekarakterer me(d differences in their relative importance. The overall deposit grade is obtained by adding up the grades for the main areas and multiplying by the weighting factor. The sum of three area grades
dividert med- '2 gir: total avleiringskarakter. divided by - '2 gives: total deposit grade.
Bedbmmelsesskalen for avleiringsrbret er oppfort i fblgende tabell: The assessment scale for the deposit body is listed in the following table:

Sammensetningen av oppfinnelsens smbreoljer og sammen-ligningsoljer, samt resultater fra oksydasjons-korrosjons-prbvene er angitt i tabell I nedenfor. Smbreoljene E, G, H og I representerer foreliggende oppfinnelse. The composition of the lubricating oils of the invention and comparison oils, as well as the results of the oxidation-corrosion tests, are given in Table I below. The spreading oils E, G, H and I represent the present invention.
Basisoljen D var en .teknisk pentaerytritol forestret med en blanding av fettsyrer som i'molprosent inneholdt ca. 18 $ isovaleriansyre, 39 i° valeriansyre, 2 $ kaprylsyre og 40 <<>fo pelargonsyre.

Smøreoljene A, B, C og D oppfyller ikke de militære spesifikasjoner-for oksydasjons-korrosjons-prover, særlig ved at de har meget dårlig viskositetskonstans og hby syredannelse. Oljen A oppfyller heller ikke korrosjonsspesifikasjonene med henblikk på kobber og magnesium. Disse olje sammensetninger viser de snevre krav som stilles til de fire additivkomponenter i henhold til oppfinnelsens oljesammensetning. Smøreoljene E, G, H og I er eksempler på sammensetninger i henhold til oppfinnelsen og de er like gode som eller bedre enn en fremragende markedsfbrt og kjent syntetisk esterbasert olje anfort i sammenligningen. The lubricating oils A, B, C and D do not meet the military specifications for oxidation-corrosion tests, particularly in that they have very poor viscosity constancy and high acid formation. Oil A also does not meet the corrosion specifications with regard to copper and magnesium. These oil compositions show the narrow requirements that are placed on the four additive components according to the oil composition of the invention. The lubricating oils E, G, H and I are examples of compositions according to the invention and they are as good as or better than an outstanding commercial and known synthetic ester-based oil cited in the comparison.
Avleiiringsegenskapene ■ f or oppfinnelsens esterbaserte smoreoljesammensetninger og markedsførte kjente syntetiske esterbaserte oljer ble sammenlignet ved Erdco avleiringsproven beskrevet oTanfor og Erdco lagerprbven, type: 1.5. Disse resultater- r?r oppfort i tabell II nedenfor: The deposition properties ■ for the invention's ester-based lubricating oil compositions and marketed known synthetic ester-based oils were compared by the Erdco deposition test described above and the Erdco stock test, type: 1.5. These results are listed in table II below:
Alle olje sammensetningene i henhold til oppfinnelsen oppfyller de gjeldende militære spesifikasjoner. Videre hadde de bedre karakterer enn en kjent smoreolje på esterbasis, smoreolje F. All the oil compositions according to the invention meet the applicable military specifications. Furthermore, they had better grades than a known ester-based lubricating oil, lubricating oil F.
Smoreoljesammensetningene C og E og en kjent esterbasert olje ble sammenlignet med hensyn på korrosivitet på rustfritt stål ved "410 Stainless Steel Corrosion Test" (korrosjonsprove for rustfritt stål, nr. 410). Ved dette forsok ble plater (2,5 x 15 x 0,32 cm) fremstilt av rustfrie stålplater nr. 410, som tilfredsstiller Aerospace Material Specification 5504 med Brinell-hårdhet på ca. B76 og overflatebehandling på 2D. To proveplater veies til nærmeste 0,1 mg og anbringes i en nikkelbombe sammen med 65 ml av den olje som skal proves. Oljen i bomben oppvarmes til 260°C og holdes ved denne temperatur i 72 timer. Deretter avkjbles oljen til romtemperatur, 5 ml olje tas ut for å bestemme total syretall og bomben inneholdende proveplater settes tilbake ved 260°C i nye 72 timer. Deretter avkjbles bomben og platene renses og veies til nærmeste 0,1 mg. Oljens viskositet ved 38°C og totalt syretall for oljen måles. Resultatene er oppfort i tabell III. The lubricating oil compositions C and E and a known ester-based oil were compared with regard to corrosivity on stainless steel by the "410 Stainless Steel Corrosion Test" (corrosion test for stainless steel, no. 410). In this experiment, plates (2.5 x 15 x 0.32 cm) were produced from No. 410 stainless steel plates, which satisfy Aerospace Material Specification 5504 with a Brinell hardness of approx. B76 and surface treatment on 2D. Two sample plates are weighed to the nearest 0.1 mg and placed in a nickel bomb together with 65 ml of the oil to be tested. The oil in the bomb is heated to 260°C and kept at this temperature for 72 hours. The oil is then cooled to room temperature, 5 ml of oil is taken out to determine the total acid number and the bomb containing the test plates is put back at 260°C for another 72 hours. The bomb is then disconnected and the plates are cleaned and weighed to the nearest 0.1 mg. The viscosity of the oil at 38°C and the total acid value of the oil are measured. The results are listed in Table III.
Ovenstående forsbk viser den vesentlig bedre evne hos smoreoljesammensetningen ifblge oppfinnelsen til å hindre korro-sjon av rustfritt stål nr. 410 sammenlignet med denne evne hos en kjent markedsfbrt olje og en lignende oljesammensetning som ikke inneholdt trikresylfosfat. The above test shows the significantly better ability of the lubricating oil composition according to the invention to prevent corrosion of stainless steel No. 410 compared to this ability of a known marketed oil and a similar oil composition which did not contain tricresyl phosphate.
Smoreoljesammensetningen i henhold til oppfinnelsen er særlig god med hensyn på oksydasjonsstabilitet, korrosjonsbeskyttelse og lav avleiringstendens som riet fremgår av de anfbrte forsbk. Smoreolje E er godkjent undtr,U.S. Navy's MIL-L-23699B-spesifikasjoner og spesifikasjoner tii Pratt og Whitney Aircraft 521B, og oljene G og H oppfyller også disse spesifikasjoner. The lubricating oil composition according to the invention is particularly good with regard to oxidation stability, corrosion protection and low depositing tendency, as can be seen from the tests cited. Lubricating oil E is approved except for the U.S. Navy's MIL-L-23699B specifications and Pratt and Whitney Aircraft 521B specifications, and the oils G and H also meet these specifications.
