Definitions

  • This invention relates to novel lubricant compositions that are useful as lubricants in high load carrying oils, e.g. metal working fluids, gear oils, extreme pressure turbine oils and hydraulic oils.
  • the lubricant compositions of the invention are especially useful in metal working fluids.
  • the cutting of metal involves the expenditure of significant amounts of energy and the development of high temperatures as the cutting tool removes metal from the workpiece.
  • the lubricant used is able to operate efficiently under the conditions of operation. This means essentially that it is capable of working at very high loads and quickly removing the heat generated by the cutting process.
  • Mineral oil alone does not have sufficient lubricity to perform this function and it is necessary to incorporate additives to enhance this aspect of the oil's performance.
  • the most common extreme pressure additives have been those containing chlorine (for example C14-17 chlorinated paraffins), phosphorus containing additives in the form of neutral triaryl phosphates, alkyl or alkylaryl acid phosphates and alkylpolyalkoxy or alkylarylpolyalkoxy acid phosphates and sulphur carriers (for example sulphurised olefins, sulphurised esters, and sulphurised fats).
  • sulphur carriers for example sulphurised olefins, sulphurised esters, and sulphurised fats.
  • the level of performance offered by the different additives varies depending on the temperatures at which the active species are released to form a salt layer at the metal surface. This in turn depends on the speed and feed rate of the cutting tool, the type and hardness of the alloy being machined and the specific machining operation.
  • oil in water emulsions and water based solutions are also commonly used in applications which require less lubricity.
  • additives are required to improve the lubrication performance of the fluid.
  • the type of phosphorus-containing additives which are found in metal working fluids are typically alkyl or alkylaryl acid phosphates and alkylpolyalkoxy or alkylarylpolyalkoxy acid phosphates used either as the free acid or neutralised with basic materials such as alkanolamines and caustic soda e.g. products sold under the trade marks of Lubrhophos and Rhodafac; neutral triaryl phosphates e.g. synthetic isopropylated phenyl phosphates such as are available commercially under the Durad trde mark.
  • One objective of the present invention is to provide a novel lubricant composition which improves the cutting performance of both neat oil and water based cutting fluids.
  • Another objective of the present invention is to replace acid phosphates as extreme pressure/anti wear additives in metal working applications. This objective has been achieved by the combination of certain neutral alkyl phosphorus compounds with certain sulphur carriers.
  • a lubricant composition for a high load carrying oil comprising:
  • the lubricant composition of the invention can comprise one or more of the compounds of general formulae I to XIII.
  • the neutral alkyl phosphorus compound and the sulphur carrier are utilised in a weight ratio of P to S content from 1:50 to 1:1, preferably a weight ratio of 1:1 to 1:30.
  • Preferred sulphur carriers are selected from at least one of sulphurised synthetic esters, sulphurised hydrocarbons (e.g. sulphurised olefins), sulphurised vegetable oils and fats, metal sulphonates, metal dialkyldithiophosphates and triaryl phosphorothionates.
  • sulphurised synthetic esters e.g. sulphurised hydrocarbons (e.g. sulphurised olefins), sulphurised vegetable oils and fats, metal sulphonates, metal dialkyldithiophosphates and triaryl phosphorothionates.
  • the sulphur carriers serve to release sulphur at the cutting face of the workpiece where it reacts to form a lubricating film at relatively high temperatures.
  • the present invention is also a high load carrying oil which contains a lubricant composition as described above.
  • the high load carrying oil may be a metal working fluid, a gear oil, an extreme pressure turbine oil or a hydraulic oil.
  • the present invention is also a method for working metal comprising (a) contacting a metal workpiece with a lubricant composition as described above and (b) working the metal workpiece.
  • the lubricant composition of the invention can include other components conventional in the art, e.g. surfactants, non-ionic alcohols.
  • Durad is a registered trade mark of Great Lakes Chemical Corporation.
  • an automatic drilling machine is used to drill holes in metal discs 40 mm thick.
  • the holes are 18 mm deep while, for oil-based cutting fluids, the drill feeds and speeds were 0.13 mm/rev (or 156 mm/min) and 1200 rpm respectively. Tests were carried out until the drill failed either due to breakage or to excessive wear. The average of at least duplicate test results are quoted.
  • the metal used was EN24T carbon steel; the drill feeds and speeds were as indicated below and the base stock was an ISO VG 22 paraffinic oil. In this case the S/P ratio was 13:1.
  • the formulation containing Durad TiBP is seen to be significantly more active than the chlorparaffin.
  • Formulation (w/w) 1 2 3 TiBP 0.6 — Sulphur carrier (36.7% sulphur - all active) 2.5 — 4.3 Chlorparaffin (40% chlorine) — 8.0 — ISO VG 22 paraffinic oil 96.9 92.0 95.7 Holes drilled to failure 280 140 100
  • B Drill Life Tests on Stainless Steel Using Neat Oil: A Comparison with Acid Phosphates
  • Stainless steel type 304 was used for this study.
  • the sulphur carriers used were a 4:1 mix of a sulphurised fatty acid ester (26% total sulphur of which 15% is active) and a dialkyl polysulphide (40% total sulphur of which 36% is active).
  • the levels of sulphur and phosphorus used were 1.5% and 0.5% respectively giving an S/P ratio of 3:1.
  • the oil used was an ISO VG 22 Group 1 base.
  • Durad TiBP is seen to be a most effective additive which in combination with the sulphur carriers shows a significant improvement over the sulphur carriers alone.
  • the sulphur carriers used RC2526 and RC2540 were the same as used in the previous Examples.
  • the drill feed rate was 150 mm/min and the speed was 1500 rpm. The depth of hole was 18 mm.
  • Formulation (w/w) Holes drilled to failure Sulphur carriers alone 56 Sulphur carriers plus Dioctyl octyl phosphonate 336 Sulphur carriers plus TBEP 500+
  • lubricity additives such as fatty oils and long chain esters can be used in cutting fluids, these were not included in the formulations shown above.
  • a major benefit of the present invention is that neutral alkyl phosphorus compounds provide a synergistic performance with sulphur carriers in both neat oil and aqueous cutting fluids on both mild steel and stainless steel. Such a synergistic combination enables the formulation of cutting fluids with the following properties:
  • neutral alkyl phosphorus compounds also allows higher levels of phosphorus to be used when necessary. Where acid phosphates are used, the acidity effectively limits the level of phosphorus that can be used because the acid can become corrosive at high levels. This allows for more flexibility in formulating mixtures of P/S and higher levels where necessary depending on the severity of the worling process.
