Description
1. Oppfinnelsens bakgrunn 1. Background of the invention
Foreliggende oppfinnelse vedrører, som angitt i krav l's ingress, en smøreoljeblanding og mer spesielt en smøreolje-blanding med forbedrede friksjonsnedsettende egenskaper og slitresistens og som er egnet som anvendelse som en smøre-olje for forbrenningsmotorer, automatgir, opphengings- og servostyrehjul og spesielt som en smøreolje for forbrenningsmotorer. The present invention relates, as stated in claim 1's preamble, to a lubricating oil mixture and more particularly to a lubricating oil mixture with improved friction-reducing properties and wear resistance and which is suitable for use as a lubricating oil for internal combustion engines, automatic transmissions, suspension and power steering wheels and especially as a lubricating oil for internal combustion engines.
2. Beskrivelse av beslektet teknikk 2. Description of Related Art
Smøreoljer blir vanligvis anvendt for drift av forbrenningsmotorer , drivmekanismer slik som automatiske gir, opphengings- og servostyringer og gir. Mer spesielt vil motor-olje være effektiv ved smøring av hovedsakelig glidende deler, slik som stempelringer og sylinderfåringer, lagre for en veivaksel eller veivstang, og ventiler innbefattende kammer og ventilløftere, for å kjøle maskinen, samt rense og dispergere forbrenningsprodukter og forhindre rustdan-nelse og korrosjon. Lubricating oils are usually used for the operation of internal combustion engines, drive mechanisms such as automatic transmissions, suspension and power steering and gears. More particularly, engine oil will be effective in lubricating mainly sliding parts, such as piston rings and cylinder liners, bearings for a crankshaft or connecting rod, and valves including chambers and valve lifters, to cool the engine, as well as clean and disperse combustion products and prevent rust formation and corrosion.
Således er forskjellige funksjoner krevd av motoroljer, og Thus, different functions are required of motor oils, and
i den senere tid har også bedre funksjoner blitt krevd når den ønskede virkningsgrad og motoreffekt blir høyere og høyere og driftsbetingelsene enda mer alvorlige. Under disse forhold blir vanligvis additiver slik som et anti-slitasjemiddel, metallisk detergent, askefritt dispergeringsmiddel og anti-oksidant innarbeidet i motoroljen for å tilfredsstille slike krav. in recent times, better functions have also been required when the desired degree of efficiency and engine power become higher and higher and the operating conditions even more severe. Under these conditions, additives such as an anti-wear agent, metallic detergent, ashless dispersant and anti-oxidant are usually incorporated into the motor oil to satisfy such requirements.
Da energitapet i friksjonsdelene hvori smøreoljen deltar er høy i motoren, blir smøreoljen vanligvis anvendt i kombinasjon med additiver slik som friksjonsmodifiserende bestand-deler (FM) for å nedsette friksjonstapene og forbedre brennstoff-forbruket (se eksempelvis Japansk patentpublika-sjon nr. 23595/1991). Ytterligere fordi motoroljen for biler anvendes under forskjellige betingelser med hensyn til oljetemperatur, motorhastighet og belastning, er det nødvendig med utmerkede friksjonsegenskaper under et vidt område av betingelser for ytterligere forbedring av brennstoff -forbruket . As the energy loss in the friction parts in which the lubricating oil participates is high in the engine, the lubricating oil is usually used in combination with additives such as friction modifying components (FM) to reduce the friction losses and improve fuel consumption (see for example Japanese patent publication no. 23595/1991 ). Furthermore, because the motor oil for cars is used under different conditions with regard to oil temperature, engine speed and load, excellent friction properties are required under a wide range of conditions to further improve fuel consumption.
Fra US 4.832.867 er det kjent en smøreolje bestående av en basisolje inneholdende minst en organofosfor komponent og en organomolybden komponent, ytterligere kan oljeblandingen inneholde et additiv slik som et salisylat. Den beskrevne smøreolje er beregnet for bruk blant annet i forbrenningsmotorer. From US 4,832,867 it is known a lubricating oil consisting of a base oil containing at least one organophosphorus component and one organomolybdenum component, furthermore the oil mixture may contain an additive such as a salicylate. The described lubricating oil is intended for use, among other things, in internal combustion engines.

MoDTC har en struktur representert ved den følgende generelle formel: The sulphurised oxymolybdenum dithiocarbamate (MoDTC) containing at least one hydrocarbon group with 8-18 carbon atoms is used as component (B). MoDTC has a structure represented by the following general formula:
hvor gruppene R<7> og R<8> i den viste generelle formel [3] hver representerer en hydrokarbongruppe med 8-18 karbonatomer. Hydrokarbongrupper med 8-18 karbonatomer innbefatter lineære og forgrenede alkyl og alkenylgrupper med 8-18 karbonatomer og cykloalkyl, aryl, alyklaryl og arylalkylgrupper med 8-18 karbonatomer.

I blandingen ifølge oppfinnelsen kan MoDTC anvendt som komponent (B) anvendes enten alene eller i kombinasjon med to eller flere av disse. Mengden av MoDTC ligger i området 50-2000 ppm, fortrinnsvis 100-1000 ppm (regnet som molybden) basert på hele blandingen. Når mengden av molybden er under 50 ppm, kan det ikke oppnås tilstrekkelig friksjonsnedsettende egenskaper, og når den er over 2000 ppm, er det ingen ytterligere signifikant forbedring i friksjonsegenskapene. Kalsiumsalisylatet med et totalt basistall på 10-100 anvendes som komponent (C) i blandingen ifølge oppfinnelsen. Kalsiumsalisylatet er eksempelvis representert med den føl-gende generelle formel: In the mixture according to the invention, MoDTC used as component (B) can be used either alone or in combination with two or more of these. The amount of MoDTC is in the range of 50-2000 ppm, preferably 100-1000 ppm (calculated as molybdenum) based on the whole mixture. When the amount of molybdenum is below 50 ppm, sufficient friction-reducing properties cannot be obtained, and when it is above 2000 ppm, there is no further significant improvement in the friction properties. The calcium salicylate with a total base number of 10-100 is used as component (C) in the mixture according to the invention.

Kalsiumsalisylatet anvendt som komponent (C) kan anvendes enten alene eller i kombinasjon med to eller flere derav. Mengden av kalsiumsalisylatet ligger i området 0,3-2,5 vekt%, regnet på hele blandingen. Når mengden av (C) er under 0,3 vekt%, oppnås ikke tilstrekkelige lave friksjonsegenskaper, og når mengden overstiger 2,5 vekt%, vil slita-sjeresistensen nedsettes og askeinnholdet økes ugunstig. The calcium salicylate used as component (C) can be used either alone or in combination with two or more thereof. The amount of calcium salicylate is in the range of 0.3-2.5% by weight, calculated on the entire mixture. When the amount of (C) is below 0.3% by weight, sufficiently low friction properties are not achieved, and when the amount exceeds 2.5% by weight, the wear resistance will be reduced and the ash content will be unfavorably increased.

(1) Koeffisient (u) : (1) Coefficient (u) :
Friksjonskoeffisienten ble bestemt ved LFW-1 prøven under betingelser av 270 o/min, 30 kp/120°C og 10 min. The coefficient of friction was determined by the LFW-1 sample under conditions of 270 rpm, 30 kp/120°C and 10 min.
Basisoljen 150N-1 (med en viskositet ved 100°C på 5,7 mm<2>/s, innehold av aromatisk komponent 4,1 vekt%, svovelinnhold 11,0 ppm og nitrogeninnhold på 89,0 ppm) eller 150N-2 (med viskositet ved 100°C på 5,5 mm<2>/s, aromatisk komponentinnhold 0,5 vekt%, svovelinnhold 0,5 ppm og nitrogeninnhold 0,1 ppm) ble anvendt. The base oil 150N-1 (with a viscosity at 100°C of 5.7 mm<2>/s, an aromatic component content of 4.1% by weight, a sulfur content of 11.0 ppm and a nitrogen content of 89.0 ppm) or 150N-2 (with viscosity at 100°C of 5.5 mm<2>/s, aromatic component content 0.5% by weight, sulfur content 0.5 ppm and nitrogen content 0.1 ppm) was used.
Hver av smøreoljeblandingene gjengitt i tabell 1 ble frem-stilt fra basisoljen, og friksjonskoeffisienten (p) ble bestemt. Resultatene er gjengitt i tabell 1-1 og 1-2. Som vist i eksemplene 1-8 i tabell 1-1 og sammenlignings-eksemplene 1-5 i tabell 1-2 utviser en smøreolje inneholdende kombinasjonen av salisylat, MoDTC og fosforsyre-ester i henhold til oppfinnelsen en signifikant lavere friksjons-koeffisient i forhold til en oljeblanding inneholdende kun to komponenter.
