Definitions

  • This invention relates to heavy-duty lubricants, and particularly to addition agents for such lubricants and to the lubricants containing the same.
  • lubricant base oils which may be petroleum fractions or synthetic liquids, with compounds containing sulfur and phosphous to improve the lubrication performance.
  • base oils can be improved to an extent not available heretofore by the addition of a synergistic mixture of metal-organic compounds and compounds free from heavy metal and containing sulfur and phosphorus.
  • the mixtures of the invention are added to natural or synthetic base oils in amounts of 0.1% to 20% of the weight of the base, the lower limit being useful for lubricants intended for relatively light duty, and the higher limit typically being reached in concentrates intended to be diluted with more base oil.
  • the lubricant ready for use should contain between 1 and 12% of a mixture of the invention.
  • the metal-organic component in the mixtures of the invention contains zinc, lead, tin, tungsten, molybdenum, niobium, lanthanum, antimony, bismuth, chromium, vanadium, or cadmium.
  • the organic moiety of the compound should include alkyl radicals, also sulfur and/or phosphorus.
  • the metal-organic compounds best suited for the mixtures of the invention are N-alkyldithiocarbamates and alkyl, aryl, and alkyl-aryl dithiophosphates of the heavy metals enumerated.
  • R R are members of the groups consisting of straight-chained, branched, and cyclic alkyl having 2 to 10 carbon atoms, and R R may be members of the same group or phenyl, o-alkylphenyl, or p-alkylphenyl, the alkyl groups of the alkylphenyls having 1-6 carbon atoms.

  • x is preferably 2, 4 or 6 and y is 2, 4 or preferably 0 when Me is molybdenum, tungsten, vanadium or chromium.
  • the dithiocarbamates and dithiophosphates of heavy metals according to the above formulas are known, and many are staple articles of commerce sold, for example, by R. T. Vanderbilt Co. Inc. of New York, NY. the following compounds are representative of the metal-organic compounds in the mixtures of the invention:
  • Lead N-diamyldithiocarbamate Lead N-dihexyldithiocarbamate, Lead N-dicyclohexyldithiocarbamate, Lead N-diheptyldithiocarbamate, Lead N-dioctyldithiocarbamate, Lead N-dinonyldithiocarbamate, Lead N-didecyldithiocarbamate, Lead N-di-n-buty1dithiocarbamate, Lead N-diisobutyldithiocarbamate, Lead N-dicyclopentyldithiocarbamate,
  • Antimony 0,0-dinonyldithiophosphate Antimony 0,0-didecyldithiophosphate, Antimony 0,0-diphenyldithiophosphate, Antimony 0,0-di-o-methylphenyldithiophosphate, Antimony 0,0-di-p-methylphenyldithiophosphate, Antimony 0,0-di-o-ethylphenyldithiophosphate, Antimony 0,0-di-o-propylphenyldithiophosphate, Antimony 0,0-di-o-butylphenyldithiophosphate, Antimony 0,0-di-o-pentylphenyldithiophosphate, Antimony 0,0-di-o-hexylphenyldithiophosphate, Antimony 0,0-di-p-hexylphenyldithiophosphate,
  • the metal-organic compounds are preferably present in lubricants of the invention which are ready for use in amounts of 0.5% to 4%, and may be present in concentrates in amounts of up to 15%, all percentage figures being by weight unless otherwise stated specifically.
  • Suitable sulfur-phosphorus compounds free from heavy metal include the phosphorus sulfides, such as P 8 P (P 8 and P 8 and corresponding polysulfides containing additional sulfur, also thiophosphates in which phosphorus is directly bound to sulfur, and the like. Sulfur may be replaced in these compounds partly or entirely by selenium or tellurium. Preferred compounds of this type are obtained by sulfurization and/or phosphorization of organic substances containing one or more olefinic double bonds, e.g. sperm oil butadienes or terpenes.
  • Sulfurized sperm oil esterified with dithiophosphate, sulfurized terpene esterified with dithiophosphate, and sulfurized sperm oil phosphated by reaction with phosphorus pentoxide are among the more complex compounds free from heavy metals which constitute the second component of the synergistic mixtures of this invention.
  • the last-mentioned compounds also are known and constitute ingredients of complex commercial mixtures, not capable of precise structural analysis, such as Anglamol 99 (Lubrizol Corp., Cleveland, Ohio), which has a nominal sulfur content of 31.5% and a phosphorus content of 1.75%.
  • the sulfur and phosphorus bearing components of the mixtures of the invention which are free of heavy metal may be present in the improved lubricants in the same amounts as the metal-organic compounds, and the same ranges of concentration are preferred.
  • the individual values, however, are preferably chosen in such a manner that the sulfur-phosphorus compounds are present in amounts of two to six times the weight of the metal-organic compound.
  • the mixtures are combined with base oils conventional in the manufacture of lubricants. Good results are obtained with mineral oils having viscosities between 1.8 E. (Engler) and C. to 35 E. at 50 C.
  • Synthetic oils such as diisodecyl phthalate, trimethyl adipate, or the dioctyl ester of sebacic acid, are most favorably affected at viscosities between 1.8 E. at 20 C. to about 65 E. at 50 C.
  • the lubricant compositions of the invention substantially reduce wear of the lubricated surfaces, improve the adhesion of the interfacial lubricant film, enhance the oxidation resistance and thus the useful life of the lubricant, and reduce the coefiicient of friction and thus the operating temperature.
  • oils of low viscosity may be employed where lubricants of high viscosity were required heretofore, as in automotive transmissions and differential gearing.
  • the same lubricant composition of the invention may be employed in an automotive vehicle in the transmission and differential gearing as well as in the engine.
  • the lubricant compositions of the invention may be adapted to a wide variety of operating conditions and unusual applications, and only few preliminary tests are needed for arriving at the most suitable composition.
  • lubricant compositions of the invention and controls were tested in an apparatus commercially available under the name Lubrimeter from Sommer & Runge in Berlin, Germany.
  • the specific testing device employed was of the improved Lohmaier design. Its basic elements are a piston pin and two small, rotating rollers frictionally engaging the pin. The wear of the pin and of the rollers under a constant load is determined.
  • the apparatus also permits the measurement of the coefiicient of friction, temperature, and contact pressure at the end of a test run. The condition of the engaged surfaces, particularly changes in the surface of the rollers, can be measured and/ or observed.
  • Terminal contact pressure, kp./mm. 102 Coeflicient of friction, after- 12 hours 0. 060 0. 062
  • Composition XII yielded the test results indicated below. It differed from Composition X in containing 1.5 cadmium N-diamyldithiocarbamate instead of the corresponding lead compound.
  • Anglamol 99 is merely representative of the phosphorus and sulfur bearing additive compositions, usually of undefinable chemical composition, which are now on the market, and tests performed with other proprietary products and with the well-defined sulfides of phosphorus show the synergistic cooperation with the metal-organic compounds described above.
  • a lubricant composition including a base oil of mineral or synthetic origin and a lubrication-improving additive containing chemically bound phosphorus and sulfur while free from chemically bound heavy metal, said additive being a member of the group consisting of sulfides and polysulfides of phosphorus, thiophosphates, and products of the sulfurization and phosphorization of organic compounds containing at least one olefinic double bond, the improvement which comprises:
  • said dithiocarbamate having the formula wherein R, and R are members of the group consisting of straight-chained alkyl, branched alkyl, and cycloalkyl, said members having 2 to 10 carbon atoms, Me is a metal of the group consisting of zinc, lead, tin, tungsten, molybdenum, niobium, lanthanum, antimony, bismuth, chromium, vanadium, and cadmium, and z is the valance of said metal and 2 or 3,
  • the amount of said lubrication-improving additive being between one and six times the weight of said dithiocarbamate.
  • said lubrication-improving additive being a phosphorus sulfide.
