摘要: A grease composition containing: (a) the reaction product of: (i) a calcium containing overbased organic acid; and (ii) at least one acid producing compound or derivatives thereof selected from group consisting (1) non-polymeric hydrocarbyl substituted dicarbonyl derivative of an acid, ester, salt, anhydride, ester-acid, acid-salt mixtures thereof; (2) copolymer derived monomers olefin; unsaturated dicarboxylic anhydride (3) inorganic about 2 more acidic hydrogens; (b) oil lubricating viscosity, wherein sulphonate contains colloidally dispersed carbonate is calcite, vaterite thereof. The invention further relates to process make its use in greases increase water resistance.
