Abstract

Wide temp. range high performance lubricants. Comprises a) a synthetic lubricant having a viscosity of 2.5 - 4.5 cSt at 210 degrees F, a V.I. of at least 120, a pour point of less than - 10 degrees C and a vaporisatn. according to Noack of at most 30%, or a predominantly iso-paraffinic fraction with uniform characteristics, or a mixture of both, b) 10-25 wt.% of a shear-stable, highly viscous hydrocarbon polymer with ax. mol. wt. of 2,000 - 60,000. They can be used in car engines in cold climates.

Description

Hochletstungsschmieröle Gegenstand der vorliegenden Erfindung sind in sehr breitem Temporaturband anwendbare, neuartige Hochleistungsschmieröle. High-performance lubricating oils are the subject of the present invention New high-performance lubricating oils that can be used in a very wide range of times.

Besonders zur Schmierung von Fahrzeugmotoren in kaltem Klima wird leichtes Anspringen des Motors auch bei extrem niedrigen Temperaturen von beispielsweise -40°C oder darunter angestrebt, während andererseits bei schwerer Belastung und forciertem Betrieb die Schmierung des Motors bei hohen Temperaturen nicht gefährdet sein darf. In gewissem Umfang werden derartige Fähigkeiten eines Motorenöls durch das US-amerikanische SAE-Klassifikationssystem (Society of Automotive Engineers) sichel gestellt, doch bezieht sich die "W" -Klassifikation der Winteröle lediglich auf maximale gemessene Viskositäten bei OOF und keineswegs auf etwa 40 Die in sehr breitem Temperaturband anwendbaren Hochleistungsschmieröle nach der Erfindung bestehen aus einem synthetischen Schmieröl in der Viskositätslage zwischen 2,5 und 4,5 cSt bei 210°F, einem VI von mindestens 120, einem Stockpunkt von unterhalb -10°C und einer Verdampfung nach Noack von höchstens 3Q olo, oder aus einer überwiegend isoparaffinishen Fraktion mit gleichen Kennzahlen oder einem Gemisch beider, und andererseits aus 10 bis 25 Gew.% eines scherstabilen hochviskosen Kohlenwasserstoff-Polymerisates mit mittlerem Molgewicht zwische 2.000 und 60.000.Especially for the lubrication of vehicle engines in cold climates easy starting of the engine even at extremely low temperatures of, for example -40 ° C or below, while on the other hand with heavy loads and forced operation does not endanger the lubrication of the motor at high temperatures may be. To a certain extent, such capabilities of an engine oil are through the US-American SAE classification system (Society of Automotive Engineers) sickle, but the "W" classification of winter oils only refers to maximum measured viscosities at OOF and by no means to about 40 Die in very High-performance lubricating oils according to the invention that can be used over a wide temperature range from a synthetic lubricating oil in the viscosity range between 2.5 and 4.5 cSt at 210 ° F, a VI of at least 120, a pour point below -10 ° C, and a Noack evaporation of at most 3Q olo, or a predominantly isoparaffinic one Fraction with the same key figures or a mixture of both, and on the other hand from 10 to 25% by weight of a shear-stable, highly viscous hydrocarbon polymer with an average molecular weight between 2,000 and 60,000.

Diese Öle können durch die Mehrberefchsbezeichnung.5 W/30 bzw.These oils can be identified by the multi-range designation. 5 W / 30 or

5 W/40 oder 5W/50 gekennzeichnet werden. Sie zeigen auch noch bei - 40° und darunter ein einwandfreies Startverhalten und geben bei Temperaturen bis etwa 300°, wie sie im Zylinderaum vorkommen können, eine Schmiersicherheit, die den Einbereichsölen der Klassen 40 bzw. 50 entspricht, während die bekannten Mehrbereichsöle der 5 W-Klasse ein relativ hohes Verdampfungsverhalten zeigen und daher weder in Bezug auf die Ölverluste noch in Bezug auf die Sicherheit der Schmierung bei sehr hohen Temperaturen befriedigen.5 W / 40 or 5W / 50. They also show at - 40 ° and below a perfect starting behavior and give at temperatures up to about 300 °, as can occur in the cylinder space, a lubrication security that corresponds to the single-grade oils of classes 40 or 50, while the well-known multigrade oils of the 5 W class show a relatively high evaporation behavior and therefore neither in In terms of oil losses still in terms of the safety of lubrication at very high satisfy high temperatures.

Die neuen Hochleistungs-Mehrbereichsschmieröle sind auf einem synthetischen Schmiermittel der Viskositätslage zwischen 2,5 und 4,5 cSt bei 210°F oder auf einer überwiegend isoparaffinischen Fraktion der gleichen Viskositätslage zwischen 2, 5 und 4, 5 cSt bei 210°F oder auf einem Genmisch dieser Fraktione, die beide einen V.I. von mindestens 120 und einen Stockpunkt von unterhalb - 10°C aufweisen, aufgebaut, wobei die erforderliche Viskosität bei hoher Temperatur durch Zusätze eines praktisch scherstabilen hochviskosen Kohlenwasserstoff-Polymeren mit mittlerem Molekulargewicht zwischen 2.000 und 60.000 im Ausmasse bis zu 25 Gew. % im Fertigöl sichergesteJlt wird. Als KW-Polymere kommen z. B. in Frage Äthylenbrightstock (Polyäthylen) oder Polyisobutylen. Daneben kön nen noch bis zu höchstens 6 Gew. % Polymethacrylate zugemischt werden.The new high-performance multigrade lubricating oils are based on a synthetic one Viscosity range lubricant between 2.5 and 4.5 cSt at 210 ° F or on predominantly isoparaffinic fraction of the same viscosity range between 2, 5 and 4.5 cSt at 210 ° F, or on a mix of genes from these factions, both of which are one V.I. of at least 120 and a pour point of below - 10 ° C, built up, the required viscosity at high temperature by adding a practical shear-stable, high-viscosity hydrocarbon polymers with a medium molecular weight between 2,000 and 60,000 in size up to 25% by weight in the finished oil will. As HC polymers, for. B. in question Äthylenbrightstock (polyethylene) or Polyisobutylene. In addition, up to a maximum of 6% by weight of polymethacrylates can be used are mixed in.
