Definitions

  • the present invention relates to lubricant compositions containing dispersed particles of lithium fluoride, calcium and / or barium.
  • a particularly recommended means consists in preparing a concentrated dispersion by mixing, for example in a ball mill, fluorides with lubricating oils.
  • dispersant In order to stabilize the dispersion, it is recommended to add a dispersant to the medium, the definition and quantity of which are chosen, in a known manner, as a function of the oil.
  • These dispersants are usually chosen from calcium or barium alkylaryl sulphonates, calcium or barium alkylphenates and polysuccinimides.
  • an ashless additive of the polysuccinimide type As dispersant.
  • compositions based on synthetic oils such as lubricating esters, esters of dicarboxylic acids and monoalcohols, esters of neopentyl polyols and mono carboxylic acids, polyethers obtained by fixing alkylene oxides on compounds with atom atoms mobile hydrogen and fluorides according to the invention are particularly interesting.
  • the dispersions in oils of mixtures of calcium and barium fluorides in the respective proportions by weight from 60 to 35 for 40 to 65 and particularly in the proportions of 1 eutectic, that is to say 38% by weight of calcium fluoride and 62% by weight of barium fluoride lead to more advantageous results than by using calcium and barium fluorides alone and characterized by their presence of the lubricant compositions of the present invention.
  • Z is constituted by a hydrogen atom and R 1 is a hydrogen atom or an alkyl radical containing from 1 to 6 carbon atoms, an aryl radical or a cyclanic radical from 3 to 10 carbon atoms, or R and Z are identical or different alkyl radicals containing from 1 to 6 carbon atoms, or Z is the group while R, is hydrogen, or an alkyl radical containing from 1 to 6 carbon atoms or the group R and R 'being either a hydrogen atom or the methyl group CH 3 , or R 1 and Z together form a linear alkylene radical of 3 to 10 carbon atoms.
  • compositions containing the two types of fluorides have friction and wear reduction properties over a wide range of loads and temperatures and lead to results superior to those obtained with traditional additives such as zinc alkyldithiophosphates.
  • compositions of the invention find application in 7 engines, transmissions hy hydraulics, deformation without metal chips, etc.
  • compositions containing as base oil the mineral oil “200 Neutral Solvent” and as additives LiF, CaF 2 , BaF 2 , the eutectic CaF 2 - BaF z containing 38% by weight of CaF 2 and 62% by weight of BaF 2 are determined using the EP Shell 4-ball machine, the description of which is given in "Annual Book of ASTM Standards", Part 24 (1979), pages 680 to 688.
  • the anti-wear test consists in applying a constant load of 70 daN for 1 hour then in measuring the diameters of the wear marks on the three fixed balls.
  • the load capacity test consists of measuring the diameters of the wear marks as a function of the load applied. The results are expressed in Wear Charge Index (I.C.U.). The operating conditions and the calculation method of the I.C.U. are described in ASTM method 2783-71 T.
  • the metal fluoride dispersions are stabilized by the ashless dispersant polysuccinimide (OLOA 1200).
  • Table 1 Also shown in Table 1 are the values of the binding load and the welding load which show that the metallic fluorides have a more marked effect at high loads than at low loads.
  • a dispersion of barium fluoride and calcium barium eutectic is prepared in a polyether (Emkarox FC 31-140), obtained by fixing a mixture of 75 parts by weight of ethylene oxide and 25 parts by weight of propylene oxide on trimethylolpropane and having an average molecular weight of 1500.
  • a polyether (Emkarox FC 31-140) obtained by fixing a mixture of 75 parts by weight of ethylene oxide and 25 parts by weight of propylene oxide on trimethylolpropane and having an average molecular weight of 1500.
  • the tests are carried out on a sphere-plane tribometer with the metallic couple Steel 100 C6 (Sphere), Cast iron G (Plan).
  • the principle diagram of the sphere-plane contact geometry tribometer appears in the review WEAR, 53 (1979), p. 10.
  • the load is 1 daN, the sliding speed of 1 mm s ⁇ 1 , the sliding length of 1 cm: 0.1 ml of lubricant deposited in the contact is used and the temperature is raised by 20 ° C min ⁇ 1 .
  • Table 3 gives the results obtained with the compositions tested, that is to say the film breaking temperature and the value of the coefficient of friction before breaking.
  • Example 12 shows that no friction reducing film is formed, the value of the coefficient of friction indicated is that obtained before the disappearance of the lubricant, in dry friction. , it reaches the value of 0.37 corresponding to the non-lubricated friction between steel and cast iron GL.
  • compositions and the results obtained are given in Table 4.
  • Table 5 shows the results obtained by dispersing in three oils containing all the conventional additives, except the anti-wear zinc dialkyldithiophosphates, 1% by weight of BaF z or of CaF 2 / BaF 2 mixture in the proportions of 1 eutectic containing 38% by weight of CaF 2 and 62% by weight of BaF 2 .
  • the main additives of these oils are polymethacrylates as freezing inhibitors and improving the viscosity index, polysuccinimides as dispersants, calcium alkylarylsulfonates as detergents.
  • Diesel oil has the particularity of containing both as dispersant-detergents, a calcium phenate, a calcium sulfonate and a polysuccinimide.
