Description
Lett bevegelig smøremiddel. Light moving lubricant.
Oppfinnelsen vedrører smøremiddel-sammensetninger, som er egnet til veivkasse- og sylindersmøring for forbrenningsmotorer, spesielt dieselmotorer. Smø-remiddelsammensetningene ifølge oppfinnelsen er spesielt egnet til smøring av sylindrene på forbrenningsmotorer når motoren drives med restbrensel, blandinger av restdestillatbrensel eller destillatbrensel som danner en stor del sure produkter ved forbrenning. Destillatbrensel som danner en stor del sure produkter ved forbrenning omfatter de som har et totalt svovelinnhold på minst 0,1 vekts-pst. The invention relates to lubricant compositions, which are suitable for crankcase and cylinder lubrication for internal combustion engines, especially diesel engines. The lubricant compositions according to the invention are particularly suitable for lubricating the cylinders of internal combustion engines when the engine is operated with residual fuel, mixtures of residual distillate fuel or distillate fuel which form a large proportion of acidic products during combustion. Distillate fuels which form a large proportion of acidic products during combustion include those which have a total sulfur content of at least 0.1% by weight.
Bruken av det ovennevnte brensel er ønskelig av hensyn til den lave pris, men det er blitt funnet at slik bruk fremkaller særlig høy sylinderslitasje på grunn av nærværet i brenselet av forskjellige uor-ganiske stoffer som svovel og i noen tilfelle vanadium og natrium. Rensing av maskiner, som bruker slikt brensel, er også utilfredsstillende. The use of the above-mentioned fuel is desirable due to the low price, but it has been found that such use causes particularly high cylinder wear due to the presence in the fuel of various inorganic substances such as sulfur and in some cases vanadium and sodium. Cleaning machines that use such fuel is also unsatisfactory.
Det er nå funnet at sylinderslitasje-graden og rensingen av maskiner som drives med slikt brensel kan forbedres vesent- It has now been found that the degree of cylinder wear and the cleaning of machines operated with such fuel can be significantly improved.
lig ved bruk av en spesiell type smøre-middelsammensetning for sylindrene. Smøremiddelsammensetningen er også en tilfredsstillende veivkassesmøring og kan derfor benyttes ved trunk-stempel-maskiner som benytter det samme smøremiddel for veivkasse og sylinder. due to the use of a special type of lubricant composition for the cylinders. The lubricant composition is also a satisfactory crankcase lubrication and can therefore be used for trunk-piston machines that use the same lubricant for crankcase and cylinder.
I henhold til oppfinnelsen er det til-veiebrakt en lett-bevegelig smøremiddel-sammensetning som omfatter en smøreolje hvori der er oppløst opptil 40 vekt-pst., for-trinsvis 5—25 vekts-pst. av en tilsetnings- According to the invention, an easily mobile lubricant composition is provided which comprises a lubricating oil in which up to 40% by weight, preferably 5-25% by weight, is dissolved. of an additive
sammensetning som består av en polymer organisk aluminiumforbindelse med den generelle formel OnAlniX1); idet X er en acetylgruppe (dvs. en gruppe som har formelen RCOO-, idet R er et alifatisk eller aromatisk kullvannstoff eller substituert kullvannstoffradikal), m, n og p er hele tall, m er ikke mindre enn 2, m/n er 0,75— 2,0 og m/p er 0,5—3,0. Det skal forstås at acylatgruppene i et hvilket som helst gitt molekyl av tilsetningen kan være like eller forskjellige. composition consisting of a polymeric organic aluminum compound of the general formula OnAlniX1); where X is an acetyl group (ie a group having the formula RCOO-, where R is an aliphatic or aromatic carbon hydrogen or substituted carbon hydrogen radical), m, n and p are whole numbers, m is not less than 2, m/n is 0 .75— 2.0 and m/p is 0.5—3.0. It should be understood that the acylate groups in any given molecule of the additive may be the same or different.
Acylatgruppene er fortrinnsvis de som er avledet fra benzoe- eller salicylsyrer, eller alifatiske monokarbonsyrer som har 12—20 kullstoffatomer, f. eks. fra stearin eller olein av handelskvalitet. The acylate groups are preferably those derived from benzoic or salicylic acids, or aliphatic monocarboxylic acids having 12-20 carbon atoms, e.g. from commercial grade stearin or olein.
Foretrukne tilsetninger er slike hvori m, n og p alle er 3, spesielt de med formelen: Preferred additions are those in which m, n and p are all 3, especially those of the formula:
idet X, X' og X" er acylat-grupper som er like eller forskjellige. wherein X, X' and X" are acylate groups which are the same or different.
De polymere organiske aluminium-forbindelser, som anvendes i sammenset-ningene ifølge oppfinnelsen, beskrives van-ligvis som polyokso-aluminium-acylater. De kan fremstilles ved oppvarming av aluminium-alkoholat med vann og karbon-syre i ett eller flere trinn og fortrinnsvis i et inert ikke flyktig fortynningsmiddel, som en lett smøreolje. Alternativt kan de fremstilles ved oppvarming av aluminium-alkoholater med karbonsyrer alene for å frigjøre alkoholen og å danne acyloksy-aluminium-alkoholatforbindelser og ytter-ligere oppvarming av sistnevnte forbin-delse. The polymeric organic aluminum compounds used in the compositions according to the invention are usually described as polyoxo aluminum acylates. They can be prepared by heating aluminum alcoholate with water and carbonic acid in one or more steps and preferably in an inert non-volatile diluent, such as a light lubricating oil. Alternatively, they can be prepared by heating aluminum alcoholates with carboxylic acids alone to liberate the alcohol and form acyloxy aluminum alcoholate compounds and further heating the latter compound.
Noen av de polymere organiske alu-miniumforbindelsene, som det er referert til ovenfor, vil når de er løst i smøreoljer forandre oljen til grease i nærvær av vann og når slike stoffer benyttes til å fremstille smøresammensetninger ifølge oppfinnelsen, er det nødvendig å tilsette et antige-leringsstoff for å bibeholde sammensetningen i en lettbevegelig form. 8-hydroksykinolin er blitt funnet å være et egnet an-ti-geleringsstoff for dette formål. Some of the polymeric organic aluminum compounds referred to above, when dissolved in lubricating oils, will change the oil to grease in the presence of water and when such substances are used to prepare lubricating compositions according to the invention, it is necessary to add an anti -clay substance to maintain the composition in an easy-to-move form. 8-Hydroxyquinoline has been found to be a suitable anti-gelling agent for this purpose.
Noen av aluminiumtilsetningene forekommer i handelen under varemerket «Manalox». Et slikt stoff som finnes i handelen (nedenfor kalt Ml) har en gele-lig-nende struktur og består av 40 vekts-pst. av en lett smøreolje og 60 vekts-pst. av et stoff med formel I, hvori % av acylatgruppene er avledet fra stearinsyre og den siste tredjedel er avledet fra benzoesyre. Et annet slikt materiale (M2) består av en oppløsning av en vektsdel iso-propyl-oleat med en vektsdel av et stoff med formel I, hvori alle acylatgruppene er avledet fra oleinsyre av handelskvalitet. Some of the aluminum additives appear in the trade under the trademark "Manalox". Such a substance found in the trade (hereinafter called Ml) has a gel-like structure and consists of 40% by weight. of a light lubricating oil and 60 wt. of a substance of formula I, in which % of the acylate groups are derived from stearic acid and the last third is derived from benzoic acid. Another such material (M2) consists of a solution of one part by weight of isopropyl oleate with one part by weight of a substance of formula I, in which all the acylate groups are derived from oleic acid of commercial quality.
Smøreoljene som benyttes i sammen-setningene ifølge oppfinnelsen er fortrinnsvis en mineralsmøreolje, spesielt en SAE 30, 40 eller 50 grads olje. The lubricating oils used in the compositions according to the invention are preferably a mineral lubricating oil, especially an SAE 30, 40 or 50 grade oil.
Det skal nå beskrives to eksempler på oppfinnelsen. Two examples of the invention will now be described.
