one of its aspects, relates more particularly to grease compositions exhibiting improved extreme pressure properties. Still more particularly, in this aspect, the invention relates to grease compositions comprising lithium complex greases containing non-heavy metal additive mixtures as extreme pressure improvers.
2. Description of the Prior Art Lithium complex greases have heretofore been widely employed in many industrial applications, and i.
particularly in instances where a high-temperature grease is required as a lubricant. In order to achieve to provide extreme pressure additives for these lithium complex greases which can impart good extreme pressure properties without the presence of heavy metal rial contains alkyl groups, each alkyl group preferably contains from 1 to 22 carbon atoms. Where the sulfurcontaining material comprises a sulfide, these sulfides preferably contain from l to l() sulfur atoms per mole.
Where the sulfur-containing material comprises sulfu- In its more specific aspects, the novel lithium complex greases of the present invention comprise calcium acetate in an amount from about 0.0 l%.,to about 50%, by weight, and from about 0.1% to about 30%, by weight, of the sulfur-containing material. Particularly desirable grease compositions are represented by a lithium complex grease in which calcium acetate is present in an amount from about 0.2% to about 15%, by weight, and the sulfur-containing material, e.g. diben- I 4 components, as heretofore employed.
