Definitions

  • these properties may be combined a very satisfactory manner by blending with a suitable mineralbase lubricating oil, preferably'one of viscosity between about 50 and 500 S. S. U. at 100 F., proportions of 0.1 to 4% by weight, based on the total composition, of degras, 0.05 to 5% of a rust inhibiting and water-emulsifying agent, such as an oil-soluble metal sulfonate of alkali or alkaline earth metal, plus about 0.5to about 10% of a compatible extreme pressure agent in the form of a sulfurized fatty oil, such as sperm oil or other and comparable animal fat, such as lard oil, sulfurized to a sulfur content of 2 to 30% by weight, and about 0.05 to about 3% of a synergistic oiliness agent and rust inhibitor, preferably in the form of an ester of an acid of phosphorus, such as tricresyl phosphate or phosphite, or the corresponding trialkyl esters, such as
  • a viscous hydrocarbon polymer It is also desirable to add a small amount, for'example, 0.05 to about 5% maximum of a viscous hydrocarbon polymer.
  • the latter ingredient adds to the tackiness and improves the viscosity index of the lubricant. It increases the resistance of the lubricant tomoisture so that it adheres to the part to be lubricated more effectively when water is present.
  • the preferred polymer is a polybutene-having a molecular weight of not less than 2,000 and not more than 100,000, preferably between 10,000 and 50,000.
  • essentially hydrocarbon'polymers and copolymers such as natural rubber, synthetic rubber like butyl rubber, and polystyrene and alkylated polystyrene may be used, provided they are sufficiently oil-soluble to remain in solution and provided they are compatible with the other ingredients.
  • Sulfurized degras may be combined with unsulfurized degras; and thus replace the sulfurized sperm oil or other animal fat. In a broad sense, a combination of; sulfurizedand unsulfurized animal fat or equivalent, seems to berequired along with the oiliness and thickener or tackiness additives.
  • the preferred ⁇ rangeof ingredients is from about 86 to about "97% by weight of'lubricating oil withil to 3% deg ra s, 0.1 to 2% of m etal sulfonate, calcium or sodium sulfonate being preferred, particularly the-former, aboutf1to;5%
  • sulfurized fatty oil','prefei sperm oil
  • sulfur content between 2 and 30%, preferably about 10 to 20%
  • about 0.5 to 2% of the oiliness agent, tricresyl phosphate being preferred for oiliness although other esters mentioned above are almost as satisfactory, and about the same proportions, namely 0.5 to 2% of a polymer, preferably polybutene or a viscous polymer of similar properties.
  • a broader range preferred is about'172 to 09% of lubricating-oil '(preferably, but not necessarily, of mineral base), 0.1 to of degras, 0.05 to of sulfurized fatty material, (or a combination of 0.15 to 1% of sulfurized and unsulfurized fatty material or" animal origin) plus the sulfonate, ester, and polymer, as given above.
  • blends s iniilai to Example 1 except not containing sulfurized sperm oil, carried only 2 to 3 weights the Alljnen test and showed humidity cabinet lives of only 72 hours.
  • Other blends containall of the additives except tricresyl phosphate carried only.
  • the humidity cabinet test given above is the standard humidity cabinet rusting test wherein a polished steel strip is coated with the lubricant and kept under conditions of approximately relative humidity at a temperature of 13. until first rusting appears. As indicated in the tables above, it is desired to have a humidity cabinet life of at least 100 hours. Plain mineral oil rusts in about one hour.
  • the composition of the present invention (Example I) ran 600 hours before rusting, whereas a conventional prior art rock drill lubricant containing 7% rapeseed oil gave a humidity cabinet life of only 24 hours. 'The products of Examples II, III and IV were of intermediate quality.
  • a lubricant for pneumatic tools, and the like consisting essentially of about 86 to 97 parts by weight of mineral base lubricatingoil having a viscosity between 50 and 500 S. S. U. at 100 F., l to 3 parts of degras, 0.1 to 2 parts of oil-soluble calcium petroleum sulfonate, 1 to 5 parts of sulfurized sperm oil containing 10 to 20% of sulfur, 0.5 to 2 parts of trieresyl phosphate and. 0.5. to. 2 parts of polybutene of molecular weight between 10,000 and 50,000.
