Abstract
An experimental grease has been formulated with 8.5 wt % lithium 12-hydroxystearate in a base oil containing an additive composition of a synergistic blend of zinc dialkyldithiophosphates, zinc diamyldithiocarbamate, aromatic amine phosphate, sulfurized sperm oil substitute and the reaction product of coconut oil and diethanolamine. The lithium 12-hydroxystearate grease has been prepared by a standard kettle procedure. The grease composition exhibits a dropping point in the range expected of a lithium complex grease. The grease keeps its soap fiber structure intact at 390.degree. to 400.degree. F., typical of the melting range of lithium 12-hydroxystearate greases. The grease is useful for its long life in constant velocity joints.
