な高温用潤滑油組成物に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a high temperature lubricating oil composition, and more particularly to a 20DC lubricating oil composition.
The present invention relates to a high-temperature lubricating oil composition that can withstand high temperatures above and is particularly effective as an engine oil.

供することができない。Conventionally, various synthetic lubricating oils have been known as high-temperature lubricants. However, the upper limit for all of these is 170C to 200C, and at higher temperatures, there is a lot of evaporation loss, causing various problems such as no lubricant present in the lubricated parts, or sludge forming, making it impossible to lubricate. It cannot be put to practical use.

There is a need for lubricants that can withstand high temperatures of 600C or higher, particularly 600C or higher. The required characteristics of a lubricant that can be used under these conditions are (1) low evaporation loss at high temperatures;
(2) no sludge is generated at high temperatures, (6) good oxidation stability, and (4) good load-bearing performance.

であることを見出し、本発明を完成するに至った。The inventors of the present invention have conducted extensive research in order to overcome the drawbacks of the conventional lubricants mentioned above and to develop a lubricant that can be used at high temperatures and has all the required properties. As a result, the inventors discovered that a lubricating oil composition comprising a specific hindered ester and mineral oil or synthetic oil is suitable for the purpose, and completed the present invention.

である。The acid that forms the ester (hindered ester) with the hindered alcohol must be an unsaturated fatty acid having 18 carbon atoms; other acids cannot provide a lubricating oil composition with desired properties. Here, as the unsaturated fatty acid having 18 carbon atoms, specifically, unsaturated fatty acids such as oleic acid, linoleic acid, and lylunic acid can be mentioned as suitable ones. It goes without saying that this unsaturated fatty acid may be used in the form of its derivatives (eg, acid halides).
