Definitions

  • the present invention relates to alkaline earth metal soap greases and particularly to new types of lubricating greases having superior high temperature properties.
  • the invention relates also to a process for making superior calcium base greases and other alkaline earth metal greases such as barium and strontium and'involv'es as one aspect, the combination of particular'types of alkaline earth metal soaps, especially calcium soaps, with other materials of low molecular weight to form the grease structure.
  • the alkaline earth metal soaps have been used to thicken oils to grease consistency and in particular lime base reases have been used for many years and. for many purposes. For relatively low operating temperatures, they have highly desirable structural characteristics, being smooth and homogeneous and quite free from oil separation.
  • the lime soap greases particularly have the serious disadvantage for some purposes however, that they require a certain small minimum Water content for stability. When this water is removed the grease breaks down. This characteristic renders the lime base greases unsatisfactory for service conditions where the Water is eliminated due to high operating temperatures, 'or other causes.
  • the other alkaline earth base greases such as barium and strontium soap greases behave somewhat similarly.
  • I base greases it is intended to include notzonly greases which are thickened with pure lime soaps, but also those mixed base greases which contain substantial quantities of the calcium soaps of fatty acids and which may also contain minor proportions of soda soaps, and the like.
  • the present invention is based, in one'aspect, upon the discovery that calcium and other alkaline earth metal soap greases may be substantially improved by the use of saturated or subused in some cases, e. g. those of boric acid and its derivatives.
  • certain hydroxy acids may be used advantageously in the preparation of some types of lubricating greases, particularly aluminum base greases and certain types of soda base greases.
  • the prior art also contains a number of susgestions for the use of various low molecular weight salts in combination with-the usual soaps employed as thickening agents.
  • certain complex salts may be formed by combining the metal derivatives of high molecular weight and low molecular weight aliphatic carboxylic acids.
  • lime base greases and mixed sodalime greases may be made more stable at high temperatures by adding acetic acid to the usual fatty acids prior to saponification so as to incorporate calcium acetate into the grease.
  • the present invention involves definite. improvements over the prior art suggestions referred to above particularly in the discovery of the unexpected properties of the hydroxy fatty acid salts of calcium and the other alkaline earth metals.
  • a conventional lime soap grease becomes unstable at temperatures around the boiling point of Water, for example above about 200 F.
  • the melting point and the useful-lubricating range of lime soap greases may beraised about to F. or more by the direct substitution of a hydroxy fatty acid for the normal fatty acid.
  • the high temperature range of this material may be raised as much as an additional 200 F. or so by adding certain of the low molecular weight materials referred to. above.
  • the peculiar properties of the hydroxy acid soaps of alkaline earth metals are not fully understood.
  • fatty acids for conventional fatty acids and the further and often-very substantial improvement resulting from the addition of low molecular weight materials to the hydroxy acid soaps.
  • Example I 1 l Percent by weight Mineral oil of 300 S. U. S. viscosity
  • the above composition was prepared inJthe conventional manner by cooking the soap forming ingredients in part of the mineral oil to a temperature between 200 and 300 F. to form the soap. The balance of the oilwas added and the mixture stirred with continued heatinguntil a homogeneous product was obtained. After cooling, a smooth grease resulted which had a workedpenetration at 77 F. of 220 mm./l and an A. S. T. M. dropping point of 283F. After storage in an oven for one hour at225 the grease was smooth and homogeneous and it retained these properties. evenv after one hour storage at 260 F. This grease was subjected to the high speed spindle test in a ball bearing operating at 10,000 R. P. M. 'at' a temperatureof 250 F. and it operated successfully for 942 hours.
  • V Ezmmple II Another composition was prepared from'the' following ingredients: r r I e Percent by'weight Mineral oil of 330 S. U. S. at 100 F.
  • the candelilla wax of Examples III and IV is' useful as a plasticizing or dispersing agent and is recommended where a smooth grease of high structure stability is desired. In other cases, its
  • non-paraifinic waxes such as montan wax, ceresin, carnauba-wax and the like.
  • compositions of strontium and various soap greases, using hydroxy acids are similarly improved over' non-hydroxy acid greases.
  • Example V using a calcium borate (formed upon neutralizationof the boric acid with calcium hydroxide), is of particular interest because of the very low cost of boric acid and the high quality of the composition obtained.
  • the calcium or other alkaline earth metal borate grease has very satisfactory properties. Its percentage of oil loss (about was somewhat high at 225 F. and it lost viscosity rapidly at higher temperatures. Nevertheless, this material appears to be quite satisfactory for lubrication at temperatures up to about 250 F. Spindle tests at this temperature and at 10,000 R. P. M. showed a useful life of 1000 hours which is remarkable for a lime base grease.
  • the corresponding saturated or substantially saturated hydroxy acids of shorter or The unsaturated hydroxy acids do not show such superiority over the corresponding normal fatty acids.
  • the mono or di-hydroxy lauric, myristic, palmitic, behenic, and other saturated acids may be employed and may be mixed in various proportions, as will be apparent to those skilled in the art.
  • the usual quantities of soap from about 5% to as much as 30%, may be used, preferably about 8 to 20% based on the weight of the total composition depending upon the consistency of the grease desired.
  • Lubricating oils are preferably the mineral base oils of about 50 to 1,000 S. U. S. viscosity at 100 F., but synthetic oils such as the esters of dibasic acids, the polyglycols, and the like, may be used alone or in combination with mineral oils. If the latter are used, the soaps should be preformed, preferably in a mineral oil slurry to avoid hydrolysis of the esters which would occur upon saponification of the fatty acids.
  • phenyl alpha naphthylamine is a desirable ingredient as an oxidation inhibitor
  • other oxidation inhibitors may be used if desired, and for many purposes such inhibitors may be omitted entirely.
  • Conventional tackiness agents, extreme pressure compounds, viscosity index improvers, corrosion inhibitors, and the like, may be included, as will be obvious to those skilled in the art.
  • the low molecular weight material is preferably a salt of an acid which acid has a molecu lar weight below about 160, and preferably below 120.
  • the proportions of such material may be varied within rather wide limits but ordinarily will be between 1% and. 10% by weight, based on the total composition. Proportions of 2% to about 6% are normally preferred.
  • a vegetable or non-paraffin wax such as carnauba or candelilla wax, or the like, as a plasticizing agent
  • the calcium salts of low organic acids such as calcium acetate are employed.
  • Such waxes may be optional in compositions which include inorganic salts such as calcium chloride or calcium borate.
