SVOVLHOLDIGE BLANDINGER OG ADDITIVKONCENTRATER OG SMOEREOLIER, DER INDEHOLDER SAADANNE BLANDINGER

摘要

The sulphur-containing, oil-soluble mixtures can be used as lubricating oil additives, in particular in lubricants which do not contain phosphorus or contain very little phosphorus. In one embodiment, the mixtures comprise (A) at least one metal salt of at least one dithiocarbamic acid of the formula in which R1 and R2 are each, independently, hydrocarbon groups, in which the total number of carbon atoms in R1 and R2 is sufficient to make the metal salt oil-soluble, (B) at least one oil-soluble, sulphurized organic compound, and (C) at least one corrosion inhibitor which serves as an auxiliary substance. The mixtures can also contain (D) at least one detergent/dispersing agent. Lubricating oils which contain these mixtures exhibit improved oxidation-corrosion-inhibiting properties, anti- wear properties and/or good properties under extreme pressures. Such lubricating mixtures which contain less than approx. 0.1% by weight of phosphorus also exhibit good compatibility with nitrile gaskets.
