Description
Oppfinnelsens bakgrunn The background of the invention
1. Oppfinnelsens felt 1. The field of invention
Foreliggende oppfinnelse vedrører en ny smøreoljeblanding, av den art som er angitt i krav l's ingress, og mer spesielt en smøreoljeblanding med forbedrede friksjonsnedsettende egenskaper og slitresistens og som er egnet som anvendelse som en smøreolje for forbrenningsmotorer, automatgir, opphengs- og servostyrehjul og spesielt som en smøreolje for forbrenningsmotorer. The present invention relates to a new lubricating oil mixture, of the kind specified in claim 1's preamble, and more particularly 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 motorolje være effektiv ved smøring av hovedsakelig gliden-de deler, slik som stempelringer og sylinderforinger, lagre for en veivaksel eller veivstang, og ventiler innbefattende kammer og ventilløftere, for å kjøle maskinen, samt rense og dispergere forbrenningsprodukter og forhindre rust-dannelse 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 cams 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 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 additiver slik som Thus, different functions are required of motor oils, and 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
2korrosjonsinhibitorer, metallsåper, askefrie dispergeringsmidler og anti-oksidanter innarbeidet i motoroljen for å tilfredsstille slike behov. 2 corrosion inhibitors, metal soaps, ashless dispersants and anti-oxidants incorporated into the motor oil to satisfy such needs.
Det er en viktig grunnfunksjon for en motorolje at motoren arbeider glatt og at oljen forhindrer slitasje og fastbren-ning under enhver gitt betingelse. I de smurte deler av en motor vil en tilstand av fluidsmøring hovedsakelig skje. Imidlertid i ventiltoget og ved topp- og bunndødpunktene for et stempel vil en tilstand av grensesmøring kunne skje. Ved slik grenseflatesmøring blir slitasje vanligvis forhin-dret ved tilsetning av sinkditiofosfat (SnDTP) eller sink ditiokarbaraat (SnDTC). It is an important basic function of an engine oil that the engine runs smoothly and that the oil prevents wear and sticking under any given condition. In the lubricated parts of an engine, a state of fluid lubrication will mainly occur. However, in the valve train and at the top and bottom dead centers of a piston, a condition of boundary lubrication may occur. With such interface lubrication, wear is usually prevented by adding zinc dithiophosphate (SnDTP) or zinc dithiocarbarate (SnDTC).
EP-A-418860 beskriver en smøreolje for en forbrennings-motor. Smøreoljen omfatter en basisolje, samt molybdenium ditiokarbamat, ytterligere kan oljen være tilsatt additiver slik som sink-ditiofosfat, jordalkaliemetallsulfonater og jordalkalimetallsalisylater. EP-A-418860 describes a lubricating oil for an internal combustion engine. The lubricating oil comprises a base oil, as well as molybdenum dithiocarbamate, the oil may also have additives such as zinc dithiophosphate, alkaline earth metal sulphonates and alkaline earth metal salicylates.
US-4832867 beskriver en smøreolje, beregnet for bruk blant annet i forbrenningsmotorer. Smøreoljen består av minst en organofosfor komponent og en organomolybden komponent i en basisolje. I tillegg kan additiver slik som sinkdialkyl-difosfater, sulfater og salisylater være tilsatt i blandingen . US-4832867 describes a lubricating oil, intended for use, among other things, in internal combustion engines. The lubricating oil consists of at least one organophosphorus component and one organomolybdenum component in a base oil. In addition, additives such as zinc dialkyl diphosphates, sulphates and salicylates can be added to the mixture.
Fordi energitapet i friksjonsdelene hvori smøreoljen deltar er høy i motoren, blir en friksjonsmodifiserende del (FM) tilsatt til smøreoljen for å nedsette friksjonstapet og forbedre brennstoff-forbruket. Som friksjonsmodifiserende bestanddeler blir vanligvis anvendt ekstrem-trykk additiver slik som molybden-forbindelser og fosforestere og oljefor-bedrere slik som fettsyre-estere og alkylaminer. Because the energy loss in the friction parts in which the lubricating oil participates is high in the engine, a friction modifying part (FM) is added to the lubricating oil to reduce the friction loss and improve fuel consumption. Extreme pressure additives such as molybdenum compounds and phosphorous esters and oil improvers such as fatty acid esters and alkylamines are usually used as friction modifying components.
Imidlertid når det anvendes en kombinasjon av anti-slita-sjemiddelet og den friksjonsmodifiserende bestanddel anvendes, vil funksjonen av begge to ikke fullt utnyttes pga. deres konkurrerende adsorpsjon på metalloverflaten. Mer spesielt vil ZnDTP og ZnDTC beskytte metalloverflåtene mot slitasje som følge av metall/metallkontakt ved å danne en beskyttende film derpå, mens den friksjonsmodifiserende bestanddel også danner en lavfriksjonsfilm ved adsorpsjon på metalloverflaten, ved reaksjon med denne eller ved dannelse av en polymer på metalloverflaten for å nedsette friksjonen. Derfor når både ZnDTP eller ZnDTC og den friksjonsmodifiserende bestanddel tilsettes smøreoljen, vil adsorpsjonsmengden av ZnDTP og ZnDTC nedsettes som følge av den konkurrerende adsorpsjon på metalloverflaten og vil nedsette slitasjeresistensen eller det vil ikke oppnås tilstrekkelig friksjonsreduserende effekt selv ved tilsetning av den friksjonsmodifiserende bestanddel. However, when a combination of the anti-wear agent and the friction modifying component is used, the function of both will not be fully utilized due to their competitive adsorption on the metal surface. More specifically, ZnDTP and ZnDTC will protect the metal surfaces against wear resulting from metal/metal contact by forming a protective film thereon, while the friction modifying component also forms a low friction film by adsorption on the metal surface, by reaction with it or by forming a polymer on the metal surface for to reduce friction. Therefore, when both ZnDTP or ZnDTC and the friction-modifying component are added to the lubricating oil, the adsorption amount of ZnDTP and ZnDTC will be reduced as a result of the competitive adsorption on the metal surface and will reduce the wear resistance or a sufficient friction-reducing effect will not be achieved even with the addition of the friction-modifying component.
På den annen side vil samvirkning mellom ZnDTP eller ZnDTC og visse detergent-dispergeringsmidler kunne skje for å nedsette slitasjeresistensen. Ytterligere kan visse additiver slik som detergent-dispergeringsmiddelet utvise en innvirkning på den friksjonsmodifiserende bestanddel. Således må valget av andre additiver slik som detergent-dispergeringsmiddelet og konsentrasjoner derav tas med i betraktning. On the other hand, interaction between ZnDTP or ZnDTC and certain detergent dispersants could occur to reduce wear resistance. Additionally, certain additives such as the detergent dispersant may have an effect on the friction modifying component. Thus, the choice of other additives such as the detergent dispersant and concentrations thereof must be taken into account.

The present invention has been provided after investigation with the intention of providing a lubricating oil mixture with improved friction-reducing and anti-wear properties and suitable for use as a lubricating oil for internal combustion engines, automatic transmissions, suspension and power steering wheels, more particularly as a lubricating oil for internal combustion engines.
