Definitions

  • Ash-containing and ashless lubricating compositions are utilised in various mechanical devices (for example stationary or mobile machinery requiring a working fluid, a hydraulic fluid, a circulating oil or a turbine oil).
  • the lubricating compositions often operate under high temperatures and/or high pressure regimes in the mechanical device.
  • the high temperatures and/or high pressure regimes are believed to decompose additives in the lubricating composition that are less thermally and/or oxidatively stable.
  • additives that tend to decompose are often ash-containing additives that contain a metal.
  • divalent metals such as zinc, calcium or magnesium, are released into the lubricating composition.
  • International Application WO 00/11 122 discloses lubricating compositions containing (I) 100 pbw of a base oil, (II) an antiwear agent comprising (i) from 0.05 to 10 pbw of a phosphorothionate and from 0.01 to 1.0 pbw of an amine salt of phosphorus compound and/or (ii) from 0.05 to 10 pbw of a dithiophosphate, and (III) a rust preventing agent comprising from 0.01 to 1.0 pbw of an amide obtained by reacting a polyalkylene polyamine and a carboxylic acid having from 4 to 30 carbon atoms.
  • the lubricating composition is suitable for hydraulic systems.
  • US Patent Application 2002/0010103 Al discloses industrial oils such as hydraulic oils containing (a) at least one a compound selected from the group consisting of a phosphoric acid ester, a thiophosphoric acid ester, and amine salts thereof; (b) at least one of a phosphorus acid ester and/or an amine salt thereof; and (c) at least one compound selected from the group consisting of an alkenyl succinimide, an alkenyl succinic acid ester, benzylamine, and derivatives thereof.
  • the present invention provides a lubricating composition and method of lubricating a mechanical device capable of reducing or minimising at least one of filter plugging, limited oxidative stability, limited thermal stability, and produce unacceptable levels of sludge.
  • the invention provides an ashless lubricating composition comprising:
  • the invention provides the ashless lubricating compositions disclosed above in the form of a concentrate.
  • the succinimide dispersant contains an average of at least about 8, or about 30, or about 35 up to about 350, or to about 200, or to about 100 carbon atoms.
  • the long chain alkenyl group is derived from a polyalkene characterised by an Mn (number average molecular weight) of at least 500.
  • the polyalkene is characterised by an Mn of about 500, or about 700, (or about 800, or even about 900) to about 5000, (or to about 2500, or to about 2000, or to about 1500, or to about 1200).
  • the long chain alkenyl group includes those derived from polyolefins.
  • the corrosion inhibitor may also be described as a metal deactivator or a yellow-metal passivator.
  • the corrosion inhibitor includes 2,5-bis(alkyl- dithio)-l,3,4-thiadiazoles.
  • the alkyl groups of 2,5- bis(alkyl-dithio)-l,3,4-thiadiazoles contain 1 to about 30, or about 2 to about 25, or 4 to about 20, or about 6 to about 16 carbon atoms.
  • the corrosion inhibitor is present in ranges including about 0.0001 wt % to about 5 wt %, or about 0.0001 wt % to about 0.5 wt %, or about 0.0001 wt % to about 0.1 wt %, or about 0.0005 wt % to about 0.06 wt % of the lubricating composition.
  • Natural oils useful in making the inventive lubricants include animal oils, vegetable oils (e.g., castor oil, lard oil), mineral lubricating oils such as liquid petroleum oils and solvent-treated or acid-treated mineral lubricating oils of the paraffinic, naphthenic or mixed paraffinic-naphthenic types and oils derived from coal or shale or mixtures thereof.
  • animal oils e.g., castor oil, lard oil
  • mineral lubricating oils such as liquid petroleum oils and solvent-treated or acid-treated mineral lubricating oils of the paraffinic, naphthenic or mixed paraffinic-naphthenic types and oils derived from coal or shale or mixtures thereof.
  • each R'" independently is hydrogen or a hydrocarbyl group, with the proviso that at least one of the R"' groups is hydrocarbyl.
  • Each hydrocarbyl group of R' " in different embodiments contains at least about 2, or at least about 4 carbon atoms. Typically, the combined total sum of carbon atoms present on both R' " groups is less than about 45, or is less than about 35, or is less than about 25. Examples of suitable ranges for the number of carbon atoms present on R groups include about 2 to about 40, about 3 to about 24, or about 4 to about 20.
