Abstract: Lubricating grease is prepared by (a) mixing a hydrophobic lubricating oil with an aqueous suspension of a water-insoluble dye, chosen from the indanthrene compounds, the indogen compounds and the phthalocyanine compounds, (b) passing the mixtures so formed over a surface having a skin temperature of 300-350 DEG F. in the form of a film 0.001-0.02 inch thick, shearing the film on the surface by means of blades travelling at a rate of 1,000-10,000 ft./min. at the point of contact with the film mixture, the residence time of the mixture on the surface being 1-30 secs., (c) passing the mixture to a heat-treating zone where the mixture is heated for a period of 0.25-4 hours at a temperature of 250-550 DEG F., and (d) subjecting the substantially anhydrous mixture to a shearing action. Lubricating oils mentioned are mineral oils, silicones, chlorinated silicones, siloxanes, aliphatic dicarboxylic esters such as bis(2-ethyl hexyl) sebacate, polyoxyalkylene compounds, polyphenyl ethers (including diphenyl ether), diphenyl, phosphate or silicate esters, phosphonates, phosphinates, and fluorocarbons (including chlorofluorocarbons). Indanthrene compounds mentioned are indanthrone, flavanthrone, pyranthrone, violanthrone, di-and tri-chloro-indanthrone, and metal derivatives thereof. The indogen compounds may carry substituents such as hydroxy, carboxy or nitro groups or halogen atoms, but the compounds specified are indigo, iso-indigo, 3-keto-indoline, isatide and isatin. The phthalocyanine compounds include metal-free phthalocyanine, metal phthalocyanines and chlorinated derivatives of either of these. The aqueous suspension of the dye may contain some relatively volatile material such as alcohols, esters or ketones. In the examples, greases are prepared from (1) methylphenyl silicone polymer oil and indanthrone and (2) bright stock mineral oil and indigo. Specification 802,896 is referred to.
