Improvements in and relating to the preparation of lubricating greases

A lubricating grease is prepared by dispersing a waterproofed clay or clay-like material in a lubricating oil in the presence of a polar organic compound miscible with the oil and having a dielectric constant greater than 10 at 20 DEG C. An increase in the gelling power of the clay, and a reduction in the milling necessary are obtained. The clay may be natural, particularly montmorillonite of high magnesia content, or synthetic clay or zeolite, e.g. made by coprecipitating silica and magnesia by adding magnesium chloride to potassium silicate solution, drying the gel, and heating with caustic soda at 240 DEG C and 450-550 p.s.i. to give a synthetic Hectorite. The magnesium chloride may be replaced by calcium, barium or aluminium chloride, and caustic soda by potash, ammonia or lithia. A preferred class of clays contains 2-20 per cent of alkaline-earth metal. The waterproofing may be effected by treating a clay hydrosol with a cationic surface active agent such as a quaternary ammonium compound or amine salt having at least one hydrocarbon radical of 12 or more carbon atoms or a partial amide of a fatty acid of at least 12 carbon atoms with a condensation product of ammonia or an amine with acrolein or its analogues or of ammonia with epichlorhydrin. The clay should contain at least 30 per cent by weight of hydrophobic surface active radicals. Another method of waterproofing clays comprises treating with a solution of a salt capable upon heating of forming basic salts, e.g. lead, barium or strontium salts of fatty acids, washing out unadsorbed salt and heating at 100-435 DEG C for 1-24 hours. Mineral lubricating oils are preferred but synthetic oils may be used such as alkylene oxide, glycol or olefin polymers, organic phosphates, silicone fluids, and carboxyclic esters. The polar compound is preferably a liquid boiling below 150 DEG C and having a dielectric constant of 15-35 at 20 DEG C.
