Title: LUBRICATING MIXTURE HAVING GLYCERIDES
Abstract:
The invention relates to a lubricating mixture, which contains glycerides of natural origin and fatty acid alkyl esters. At least some of the glycerides are mono- and/or diglycerides, which form a mass fraction of ≥ 10% in the mixture. In a temperature range of > 10°C to at least 15°C, the mixture has a liquid phase having a solid fraction of 1 vol%, which solid fraction is formed from a fraction of the glycerides and/or of the fatty acid alkyl esters. The mixture can be formed completely from renewable raw materials, has a high viscosity index, and is suitable especially as a lubricant for use in gearings, electric motors, or internal combustion engines.
