High performance lubricating oil

The present invention relates to a high-Sohmleröl (engine, transmission, transducer, machine oils) _f on the basis of clay mineral mixtures and synthetic Schaleretoff En 1st characterized in that it

Ι »from paraffinic oils in which the level of the incipient paraffin excretion (BPA) is below -1O ⁰ C and which have a VI of over 95,

2. from naphthembase oils with an etook point below -35 ⁰ C and a VI above 60, and

3. Consists of a proportion of synthetic lubricant (higher molecular β ester with more than an ester group) with a pour point below -4O ⁰ C and an average VI above 140.

As a precautionary measure, a fraction xu that has been subjected to dewaxing is to be selected as the base oil with no paraffin base. Ee is sweakmäfllg, the Faraffin excretion so urinate that it occurs only significantly below -XO ⁰ C, if possible only below -20 ° to -25 ⁰ C,.

Alnaphtheabasic constituent is used appropriately a core fraction, which · τοη lower-boiling fractions largely exempted 1st. See Bum for example by examining the oxidative Terdaapfungsverhalteme in each case u * teach ».

Dae naphthene ^ Ul should own a pour point ", which is preferably less than -35 ⁰ C, -40 ⁰ C and below." The YI of the oil should be at least 60, but preferably over 65 »

High molecular weight esters with more than one ester group serve as synthetic lubricants, namely both those made from dihydric or polyhydric alcohols with monocarboxylic acids and those made from carboxylic acids with more than one acid group with monoalcohols, whereby the components can be straight or branched chain and the molecule at least Should contain 20 carbon atoms. The prayers should have a stack point tone below -4O ⁰ C _r, preferably below -5O ⁰ C, and a ¥ 1 tone above 140, preferably above 160 _T. This also applies to ester mixtures, in which one Eatertjp can have better, the other lesser characteristics. The mixture should, however, meet the stated conditions.

The oil shows particularly advantageous properties if the lubricant contains an ester component that has at least one branch in the d. -Position contains *

It may be eweokaäSig, a DAQ · Koaponemte a having a viscosity of at least 5 * 5 cSt (at 21O ⁰ F) _9, and a component such t5 below 3 cSt (at 210 ⁰ P). In this way it is possible, on the one hand, to give the synthetic Sohmieretoff a high load-bearing capacity and, on the other hand, to use its rheological effect to achieve low viscosities at low temperatures.

The proportion of synthetic lubricant should be τοη a few «present (sB, 3 to 5) up to 25%, but not more. Bs can also partly consist of polyaers of unsaturated hydrocarbons with a sehalerulo character.
