method for preparing a sulfonate-based grease, and, sulfonate-based grease composition

摘要

a base excess calcium magnesium sulfonate grease composition and manufacturing method comprising both base excess calcium sulfonate and base excess magnesium sulfonate in a ratio range of 60:40 are provided. at 100: 1. The grease is prepared according to any known method for preparing a base excess calcium sulfonate grease using base excess magnesium sulfonate in addition to base excess calcium sulfonate. one portion of the magnesium sulfonate may be added prior to conversion and another portion after conversion with or without one or more delayed periods between the addition of water or other reactive ingredients and the addition of magnesium sulfonate. The grease may be prepared using added calcium hydroxyapatite and / or calcium carbonate as calcium-containing bases to react with complexing acids, a non-aqueous conversion agent delay method, added alkali metal hydroxide, or any combination thereof. The grease has a high drop point and reduced thickener yield.
