  • A MIXED COMPLEX SOAP BASED GREASE COMPOSITION AND METHOD FOR PREPARATION THEREOF
    Publication number: 20240209279
    Abstract: The present invention relates to a mixed complex soap based grease composition comprising a lubricating base oil; a saponifiable material; a metal oxide; an alkali/alkaline metal hydroxide; and a complexing acid. The present invention also discloses a single-step, open kettle, energy-efficient process which gives smooth textured zinc-alkali/alkaline earth metal mixed complex grease composition with relatively low thickener content while still maintaining desired consistency. The zinc-alkali/alkaline earth metal mixed complex grease composition is tailor made to have dropping point in a range of 180° C. to 300° C. comparable to lithium and lithium complex grease composition, have inherent oxidation stability, extreme pressure, anti-wear properties, and water resistance properties. The zinc-alkali/alkaline earth metal mixed complex grease composition shows excellent additive response good mechanical stability, low temperature properties, pumpability, and corrosion resistance.
