Description
NO-PS 122.141 vedrører en smøremiddelblanding som om- NO-PS 122.141 relates to a lubricant mixture which
fatter en hydrokarbon-smøreolje, (a) minst ett oljeløselig basisk salt av minst én naftensyre og minst ett metall fra gruppe II i det periodiske system med atomnummer fra 12 til 56, og (b) minst ett oljeløselig basisk salt av minst én aromatisk karboksylsyre og minst ett metall fra gruppe II i det periodiske system med atomnummer fra 12 til 56. comprises a hydrocarbon lubricating oil, (a) at least one oil-soluble basic salt of at least one naphthenic acid and at least one metal from Group II of the periodic table with atomic numbers from 12 to 56, and (b) at least one oil-soluble basic salt of at least one aromatic carboxylic acid and at least one metal from group II in the periodic table with atomic numbers from 12 to 56.
Smøremidlet i henhold til ovennevnte patent er egnet for smøring av både slike hjelpemidler som dieselgeneratorer og lagre i hovedmotorene ombord i skip. The lubricant according to the above-mentioned patent is suitable for the lubrication of such aids as diesel generators and bearings in the main engines on board ships.
Det er i mellomtiden kommet et behov for smøreoljer som In the meantime, a need has arisen for lubricating oils such as
har meget høye TBN-verdier, f.eks. høyere enn 12. Med TBN menes det totale basetall som bestemmes elektrometrisk (TBN-E). have very high TBN values, e.g. higher than 12. TBN means the total base number determined electrometrically (TBN-E).
Dette behov har særlig manifestert seg ved smøring av sylindere i motorer som har separate smøresystemer for sylindere og lagre, slik som de store, lavhastighets-dieselmotorer som anvendes ombord i skip. For motorer av denne type anvendes tunge brenseloljer som inneholder relativt store mengder av svovel, mens trykk som påføres i disse motorer, blir større. Dette resulterer i øket korrosjonsproblem i sylindrene, som krever anvendelse av stadig større TBN-verdier. This need has particularly manifested itself in the lubrication of cylinders in engines that have separate lubrication systems for cylinders and bearings, such as the large, low-speed diesel engines used on board ships. For engines of this type, heavy fuel oils are used which contain relatively large amounts of sulphur, while the pressure applied in these engines is greater. This results in an increased corrosion problem in the cylinders, which requires the use of increasingly large TBN values.
Siden additiv (a) er billigere enn additiv (b) og til-gjengelig med høyere basisitet, er det innlysende å øke konsen-trasjonen av dette additiv, desto mer siden antioksydasjdnsegen-skapene til det dyrere additiv (b) alltid ansees å være av:mindre viktighet for slike "én gang gjennom"-sylinderoljer, hvilket be-kreftes ved anvendelsen av bare additiv (a) i de eksisterende sylinderolj er. Since additive (a) is cheaper than additive (b) and available with higher basicity, it is obvious to increase the concentration of this additive, the more so since the antioxidant properties of the more expensive additive (b) are always considered to be of : less importance for such "once through" cylinder oils, which is confirmed by the use of only additive (a) in the existing cylinder oils.
Det er nå funnet at ved TBN-verdier i overkant av 50, spesielt over 70, f.eks. 100, resulterer anvendelsen av bare addi- It has now been found that at TBN values in excess of 50, especially above 70, e.g. 100, the application of only addi-
tiv (a) i sylinderoljer i meget hårde avsetninger i sylinderne, hvilket bevirker skrammer på sylinderveggen. tive (a) in cylinder oils in very hard deposits in the cylinders, which causes scratches on the cylinder wall.
Det er nå overraskende funnet at disse hårde avsetninger ikke dannes hvis de nevnte høye TBN-verdier oppnås ved anvendelse av en kombinasjon av additivene (a) og (b). It has now surprisingly been found that these hard deposits do not form if the aforementioned high TBN values are obtained by using a combination of the additives (a) and (b).
Oppfinnelsen vedrører derfor et smøremiddel, spesielt en sylinderolje, som omfatter en hydrokarbon-smøreolje, (a) et olje-løselig basisk salt av en naftensyre og et metall fra gruppe II i det periodiske system med atomnummer mellom 12 og 56, og (b) et oljeløselig basisk salt av en aromatisk karboksylsyre og et metall fra gruppe II i det periodiske system med atomnummer mellom 12 og 56, idet TBN-verdien er over 12 mg KOH/g. The invention therefore relates to a lubricant, in particular a cylinder oil, comprising a hydrocarbon lubricating oil, (a) an oil-soluble basic salt of a naphthenic acid and a metal from Group II of the periodic table with atomic numbers between 12 and 56, and (b) an oil-soluble basic salt of an aromatic carboxylic acid and a metal from group II in the periodic table with atomic numbers between 12 and 56, the TBN value being above 12 mg KOH/g.
TBN-verdien overstiger fortrinnsvis 50, spesielt 70, og er f-eks. omkring 100. The TBN value preferably exceeds 50, especially 70, and is e.g. around 100.
Additivene (a) og (b) kan begge anvendes i mengder på 0,5-20 vekt%, basert på hele blandingen, i hvilken additiv (a) fortrinnsvis anvendes i mengder på 3-20 vekt% og additiv (b) i mengder på 6-20 vekt%. (a):(b)-vektforholdet er fortrinnsvis mellom 1:5 og 5:1, f.eks. mellom 2:1 og 3:1. The additives (a) and (b) can both be used in amounts of 0.5-20% by weight, based on the entire mixture, in which additive (a) is preferably used in amounts of 3-20% by weight and additive (b) in amounts of 6-20% by weight. The (a):(b) weight ratio is preferably between 1:5 and 5:1, e.g. between 2:1 and 3:1.
Basisiteten til additiv (a) er fortrinnsvis over 400%, spesielt over 600%, og er f.eks. 800 og opp til mer enn 1000%. Basisiteten til additiv (b) er fortrinnsvis over 150%, f.eks. 200%, selv om verdier på 600% og høyere også er egnet. Basisiteten er her definert ved formelen - 1) x 100%, hvor M er antall metall-ekvivalenter, og E er antall ekvivalenter av organisk syre i det basiske salt. Additivene (a) og (b) kan med fordel tilsettes i form av konsentrater, f.eks. i spindelolje. The basicity of additive (a) is preferably above 400%, especially above 600%, and is e.g. 800 and up to more than 1000%. The basicity of additive (b) is preferably above 150%, e.g. 200%, although values of 600% and higher are also suitable. The basicity is here defined by the formula - 1) x 100%, where M is the number of metal equivalents, and E is the number of equivalents of organic acid in the basic salt. Additives (a) and (b) can advantageously be added in the form of concentrates, e.g. in spindle oil.
Egnede additiver (a) stammer fra naftensyrer som har en gjennomsnittlig molekylvekt på mellom 150 og 750, og fra metallene barium, kalsium, magnesium eller sink, fortrinnsvis kalsium. Suitable additives (a) originate from naphthenic acids having an average molecular weight of between 150 and 750, and from the metals barium, calcium, magnesium or zinc, preferably calcium.
Egnede additiver (b) kan også stamme fra disse metaller, fortrinnsvis kalsium. De aromatiske karboksylsyrer som anvendes, kan være hydrokarbonsubstituerte benzoesyrer, salicylsyrer, resorcylsyrer eller antranilsyrer. Eksempler er C3-C22-alkyl-benzoesyrer, C3-C22-alkylsalicylsyrer, f.eks. laurylsalicylsyrer, stearylsalicylsyrer eller blandinger av Cg-C3C|-alkylsalicylsyrer. C14-C22-alkylsalicylsyrer, spesielt blandinger av C14-C18-mono-alkyl og dialkylsalicylsyrer, er meget godt egnet. Suitable additives (b) can also originate from these metals, preferably calcium. The aromatic carboxylic acids used can be hydrocarbon-substituted benzoic acids, salicylic acids, resorcylic acids or anthranilic acids. Examples are C3-C22-alkyl-benzoic acids, C3-C22-alkylsalicylic acids, e.g. lauryl salicylic acids, stearyl salicylic acids or mixtures of C 8 -C 3 C 1 -alkyl salicylic acids. C14-C22 alkyl salicylic acids, especially mixtures of C14-C18 mono-alkyl and dialkyl salicylic acids, are very suitable.
Alkylsalicylsyrer som har minst en al.kylgruppe med mer enn 12 karbonatomer og hvor en alkylgruppe opptar para-stillingen tilhydroksylgruppen, er også godt egnet- Disse kan f.eks. være fremstilt ved to-trinns alkylering av fenol med olefiner og isobuten. Alkyl salicylic acids which have at least one alkyl group with more than 12 carbon atoms and where an alkyl group occupies the para-position to the hydroxyl group are also well suited - These can e.g. be produced by two-stage alkylation of phenol with olefins and isobutene.
Andre additiver kan også anvendes, f.eks. i mengder av 0,1-10 vekt% av hvert, f.eks. antioksydasjonsmidler, antislitasje-additiver og skumhindrende midler. Viskositetsindeks-forbedrende midler og dispergeringsmidler, f.eks. polare eller upolare poly-merer, er også egnet som additiver. Other additives can also be used, e.g. in amounts of 0.1-10% by weight of each, e.g. antioxidants, anti-wear additives and anti-foaming agents. Viscosity index improvers and dispersants, e.g. polar or non-polar polymers are also suitable as additives.
Hydrokarbon-smøreoljen kan være en mineralolje og/eller syntetisk olje. Andre syntetiske oljer, f.eks. ester-smøreoljer, kan blandes med basisoljen. Hydrokarbon-smøreoljene kan være destillatoljer eller blandinger derav med restoljer, f.eks. så-kalte "bright stocks". Vegetabilske, og animalske oljer kan også blandes med basisoljen. The hydrocarbon lubricating oil can be a mineral oil and/or synthetic oil. Other synthetic oils, e.g. ester lubricating oils, can be mixed with the base oil. The hydrocarbon lubricating oils can be distillate oils or mixtures thereof with residual oils, e.g. so-called "bright stocks". Vegetable and animal oils can also be mixed with the base oil.

After each test, the upper piston ring was removed, all rings were shifted a single position, and a new ring was placed in the lowest groove.
Testens varighet: 400 timer Duration of the test: 400 hours
Hastighet ved hvilken oljen fordeles: ca. 1 g/kWh Speed at which the oil is distributed: approx. 1 g/kWh
Oljeprøvene ble oppsamlet under hele testen. The oil samples were collected during the entire test.
Ringslitasjen for hver test er definert som vekt-tapet fra de øvre tre stempelringer. The ring wear for each test is defined as the weight loss from the upper three piston rings.
Resultatene er gjengitt i følgende tabell. The results are reproduced in the following table.
Det kan sees av denne tabell at ved en TBN-verdi over 70, It can be seen from this table that at a TBN value above 70,
nemlig ca. 100, og ved anvendelse av bare additiv (a), er ring- namely approx. 100, and using only additive (a), ring-
slitasjen faktisk mindre, men at sylinderveggene er oppskrapet. the wear is actually less, but the cylinder walls are scratched.
Kombinasjonen av additiveiVe (a) og (b) forårsaker på den The combination of additive effects (a) and (b) causes on it
annen side ikke oppskraping ved en TBN-verdi på omkring 100, mens slitasjen av den nederste ring beholdes. on the other hand, no scratching at a TBN value of around 100, while the wear of the bottom ring is retained.
