Method for producing a complex super-calcium calcium sulfonate grease and complex calcium sulfonate grease composition

摘要

a superbasic calcium sulfonate grease composition and method for manufacturing comprising alkali metal hydroxide added alone or in combination with (a) calcium hydroxyapatite and / or added calcium carbonate used as calcium containing bases to react with complexing acids) and / or (b) at least one time delay between adding water as a conversion agent and adding a portion of a non-aqueous conversion agent. A delay period may involve the length of time it takes to adjust the temperature of the mixture, a period of time during which the mixture is kept at or within a temperature range and multiples, and any combination thereof. These calcium sulfonate greases have improved thickener yield and high drop points compared to greases made without added alkali metal hydroxide and delay between water additions and a non-aqueous converting agent, particularly when a low-grade superbasic calcium sulfonate Quality is used.
