High-performance, multi-range lubricating oils. Comprise a) a predominantly isoparaffinic component in viscosity range 2.5 - 4.5 cSt at 210 degrees F, a V.I. at least 120, a pour pt. below 0 degrees C, or a mixture of such a component with a synthetic lubricant with the same characteristics and b) a mineral oil with a V.I. above 90 at a viscosity of at least 5.0 cSt at 210 degrees F or a brightly viscous synthetic component with a V.I. above 120 at a viscosity of at least 20 cSt at 210 degrees F, or a mixture of the two. The oils have improved swelling behaviour.

Description

Hochleistungs -Mehrbereichsschmieröle Gegenstand der vorliegenden Erfindung sind Ilochleistungs - Mehrb ereichs -schmieröle, die sich insbesondere durch vorzügliches Quellverhalten gegen Elastomere auszeichnen. High-performance multigrade lubricating oils are the subject of the present Invention are Ilochleistungs - multigrade lubricating oils, which are in particular characterized by excellent swelling behavior towards elastomers.

Die neuartigen Schmieröle bestehen einerseits aus einer vorwiegend isoparaffinischen Komponente im Viskositätsbereich zwischen 2, 5 und 4, 5 cSt bei 2100F, mit V.I. mindestens 120, Stockpunkt unterhalb OOC oder einem Gemisch einer solchen vorwiegend isoparaffinischen Komponente mit einem synthetischen Schmieröl mit gleichen Kennzahlen, in dem der Anteil vorwiegend isoparaffinischerKomponente mindestens die Hälfte des Anteiles an synthetischem Schmieröl beträgt, und andererseits aus einem Mineralöl mit V. I. über 90 in der Viskositätslage von mindestens 5, 0 cSt bei 2100F oder einer hochviskosen synthetischen Komponente mit V.I. über 120 in der Viskositätslage von mindestens 20 cSt bei 210°F, oder einem Gemisch beider. The new types of lubricating oils consist on the one hand mainly of one isoparaffinic component in the viscosity range between 2.5 and 4.5 cSt 2100F, with V.I. at least 120, pour point below OOC or a mixture of one such a predominantly isoparaffinic component with a synthetic lubricating oil with the same key figures in which the predominantly isoparaffinic component is at least half the proportion of synthetic lubricating oil, and on the other hand from a mineral oil with V.I. over 90 in the viscosity range of at least 5.0 cSt at 2100F or a high viscosity synthetic component with V.I. over 120 in the viscosity range of at least 20 cSt at 210 ° F, or a mixture of both.

Es ist bekannt, Hochleistungs-Mehrbereichsschmieröle mit verbessertem Kälteverhalten sowie gleichzeitig erhöhter Schmierwirkung in der Hitze, die auf Grund ihrer geringen Flüchtigkeitsneigung und hoher Oxidationsstabilität zugleich Langzeitschmierölcharakter aufweisen, dadurch herzustellen, dass niedrigviskose synthetische Komponenten geringer Flüchtigkeitsneigung , ins -besondere solche auf Ester-Basis, mit höherviskosen Mineralöliraktionen von a priori geringer Flüchtigkeitsneigung vermischt werden. It is known, high-performance multigrade lubricating oils with improved Cold behavior and at the same time increased lubricating effect in the heat, which on Because of their low volatility and high oxidation stability at the same time Have long-term lubricating oil character, thereby producing that low-viscosity synthetic components with low volatility, especially those on Ester-based, with higher viscous mineral oil actions with a priori low tendency to volatility be mixed.

Solche Grundölmischungen sind gleich viskosen, rein mineralischen Grundölen im Hinblick auf die vorgenannten Eigenschaften umso mehr überlegen, je höher der Gehalt an niedrigviskoser synthetischer Komponente gewählt wird. Hier ist jedoch eine Grenze durch den Umstand gesetzt, dass mit zunehmendem Gehalt an niedrigviskoser synthetischer Komponente die oberen Grenzen der jeweils zulässigen QueUung von Elastomeren-Dichtungen erreicht bzw. überschritten werden. Such base oil mixtures are viscous, purely mineral With regard to the aforementioned properties, the more superior the base oils higher the content of low-viscosity synthetic components is chosen. here However, a limit is set by the fact that with increasing content of low-viscosity synthetic components exceed the upper limits of the permissible in each case QueUung of elastomer seals can be reached or exceeded.

Gemäss vorliegender Erfindung kann die niedrigviskose synthetische Komponente ganz oder teilweise ersetzt werden durch vorwiegend isoparaffinische Fraktionen ähnlicher Viskositätslage, und zwar im Bereich 2, 5 bis 4,5 cSt bei 210 F, deren Quellverhalten an sich wesentlich niedriger liegt als jenes üblicher Mheralölfraktionen gleicher Viskositätslage, wovon die Solventraffinate ca. 100 V.I. aus paraffinbasischen Rohölen noch die relativ geringste Quellung zeigen.According to the present invention, the low-viscosity synthetic Component can be replaced in whole or in part by predominantly isoparaffinic Fractions of similar viscosity, in the range from 2.5 to 4.5 cSt at 210 F, whose swelling behavior is essentially lower than that of conventional mineral oil fractions same viscosity level, of which the solvent raffinates approx. 100 V.I. from paraffin-based Crude oils still show the relatively slightest swelling.

Vorwiegend isoparaffinische Fraktionen können in Bezug auf die viskositätserniedrigende Wirkung ohne nachteiligen Einfluss auf die Flüchtigkeitseigenschaften und in Bezug auf ein flaches Viskositäts - Temperatur - Verhalten (V. ) synthetische Komponenten des Viskositätsbereiches 2, 5 bis 4, 0 cSt bei 2100F weitgehend ersetzen und dadurch die Wirtschaftlichkeit der Herstellung solcher Hoch -leistungs-Mehrbereichss chmieröle verbessern. Da vorwiegend isoparaffinische Fraktionen gegenüber Elastomeren weitgehend indifferent sind, sind sie allein oder in Mischung mit niedrigviskosen synthetischen Komponenten geeignet, hinsichtlich der Quellungseigenschaften wesentlich verbesserte Schmieröle nach Verschnitt mit höherviskosen Mineralölen und/oder hochviskosen synthetischen Schmiermitteln herzustellen.Predominantly isoparaffinic fractions can be used in relation to the viscosity-lowering Effect without adversely affecting the volatility properties and in relation on a flat viscosity - temperature behavior (V.) synthetic components of the viscosity range 2.5 to 4.0 cSt at 2100F largely replace and thereby the economic viability of producing such high-performance multigrade lubricating oils to enhance. As predominantly isoparaffinic fractions compared to elastomers largely are indifferent, they are used alone or in a mixture with low-viscosity synthetic Components suitable, significantly improved in terms of swelling properties Lubricating oils after blending with higher-viscosity mineral oils and / or high-viscosity synthetic oils Manufacture lubricants.

Vorzugsweise isoparaffinische Komponenten mit einem Anteil an paraffinischen Kohlenwasserstoffen von über 60 olo können technisch gewonnen werden durch thermisch-katalytische Isomerisation von Normalparaffinen, durch "Hydrotreating" von Mineralölen oder durch Abtrennung der Normalparaffine aus Harnstoff-Gatschen, die im wesentlichen aus einer Mischung von Normal- und Isoparaffinen bestehen, bzw. durch Gewinnung der Weichparaffine aus entparaffinierten Mineralölen mittels Harnstoff.Preferably isoparaffinic components with a proportion of paraffinic Hydrocarbons of over 60 olo can be obtained technically by thermal-catalytic Isomerization of normal paraffins, by "hydrotreating" mineral oils or by Separation of normal paraffins from urea slacks, which essentially consist of a Mixture of normal and isoparaffins exist, or by extracting the soft paraffins from dewaxed mineral oils using urea.
