  • the invention relates to compounds which can be obtained by mixing and / or grinding a phosphate and a solid lubricant component, and to lubricants containing such compounds in mixed and / or ground form.
  • DE-OS 21 04 041 and DE-OS 29 21 620 describe adding lubricating oils to the addition products of dialkyldithiophosphoric acids as lubricant additives in amounts of 0.1 to 5% by weight.
  • the present invention relates to compounds obtainable by mixing and / or grinding a phosphate and a solid lubricant component.
  • the phosphates to be used according to the invention are known compounds and e.g. in DE-OS 21 04 041, US Pat. No. 4,456,539 and US Pat. No. 3,919,158.
  • phosphates of the general formulas I, II or III wherein R1 and R2 are independently C1-C25 alkyl or unsubstituted or substituted with 1 to 3 C1-C8 alkyl groups, phenyl or naphthyl, X and Y are independently oxygen or sulfur, R3 is C1-C5 alkyl, R4 is an alkoxy radical which is derived from an aliphatic C2-C20 alcohol with 1 to 4 hydroxyl groups, R5 is hydrogen or C1-C3 alkyl, R6 and R7 independently of one another are C1-C20 alkyl, C5-C8 cycloalkyl or unsubstituted or substituted by 1 to 3 C1-C8 alkyl groups Phenyl or naphthyl mean, M a Metal cation or ammonium, n is an integer corresponding to the valence of the cation M and t is an integer from 1 to 4, which corresponds to the functionality of the alcohol
  • R1, R2, M and n can be found in US Pat. No. 4,456,539. At least one of the radicals X and Y is preferably sulfur, but in particular both. M is preferably Zn.
  • R3 is defined in U.S. Patent 3,919,158.

  • At least one of the radicals X and Y is preferably sulfur, but in particular both.
  • Of particular interest is the phosphate (iso-C3H7O) 2P (S) -S-CH2CH2COOC2H5.
  • Liquid phosphates are of particular interest.
  • the solid lubricant component or mixtures thereof is used in particular in amounts of 50 to 90% by weight and can include from the series graphite, the bisulfides and selenides Des Mo, Nb, Ta, Ti and W, boron nitride, lead sulfide, from the intercalation compounds of graphite the metal chlorides NiCl2, CoCl2, CrCl3, YCl3, PtCl4, RuCl3, PdCl3, RhCl3, AlCl3, with graphite the metals Co, Ni, Fe, Cu, Rh, Pt, Od, Ru, and the graphite fluorides (CF x ) n , where x is greater than 1, are selected.

  • a graphite of lubricant quality with a carbon content of greater than 85% and preferably greater than 90% and a crystallite length of L c greater than 50 nm and preferably greater than 60 nm is expediently used as the solid lubricant.
  • Particularly preferred compounds contain 5 to 35% by weight of the compound (iso-C3H7O) 2P (S) -S-CH2-CH2COOC2H5 and 65 to 95% by weight of a graphite in lubricant quality with a carbon content of greater than 95% and preferably greater than 90% and a crystallite length L c of greater than 50 nm and preferably greater than 60 nm.
  • the compounds according to the invention are produced in such a way that the solid lubricant component is in direct contact with one another in the presence of the phosphate by constant mixing, it being possible to produce active fracture surfaces.
  • This manufacturing process can therefore also represent a simultaneous mixing and grinding process, expedient new fracture surfaces on the individual particles of the solid lubricant component are generated by a mixing and / or grinding operation, preferably in a ball mill.
  • a roller steel can also be used.
  • impact crushers e.g. Hammer mills, impact mills, jet mills, or in the sense of wet grinding.
  • lubricant component e.g. in a kneader
  • premixed product it may also be convenient to premix the lubricant component, e.g. in a kneader, and subject the premixed product to grinding as described.
