Definitions

  • This invention concerns a functional fluid, preferably a gear oil, that is compatible with water-based functional fluids used in metaiworking operations.
  • Functional fluids are primarily used to prevent metal-to-metal contact between moving metal parts. Functional fluids also act by reducing friction and protecting against corrosion, thereby increasing the working life of the metal parts.
  • Functional fluids such as gear oils are used in, for example, worm gear boxes as transmission fluids in cars and in machine presses that deform metal sheets, such as tin coated steel or aluminium sheets, to produce deformed components such as metal cans.
  • gear oils that are currently used in the deformation of steel or aluminium are based on mineral oils. Although mineral oil fluids are good gear oils, they contaminate water based functional fluids that are also used in the production of the metal cans. Also, residues from the gear oil can remain on the cans, which then need to be removed by, for example, expensive, high energy cleaning processes, before the cans can be finished with, for example, lacquers or paints.
  • the mineral oils can also contaminate the cleaning fluids used in the cleaning processes, which means that the cleaning fluids need to be disposed of by following environmental guidelines and regulations. This can be costly and time-consuming.
  • water based functional fluids are also used in the production of cans.
  • the water based functional fluids can include, for example, deformation fluids that are used primarily to provide lubricity during deformation of the tin coated steel or aluminium
  • the deformation fluid also protects against corrosion and bacterial and fungal infestation
  • the deformation fluid can be used as both a 'prelube' to coat the metal steel prior to deformation and a lubricant and coolant during the deformation process
  • the deformation fluid does not include any mineral
  • a further aim of the present invention is to be able to produce a can in a can-forming process that is sufficiently clean (i e sufficiently free from mineral oil residue) that cleaning processes such as high energy cleaning processes are not required before the can is lacquered or painted
  • a further aim of the present invention is to provide a functional fluid such as a gear oil that is compatible with water based functional fluids that are also used in metal working operations
  • a further aim of the present invention is to provide a functional fluid that does not cause as much contamination as functional fluids based on mineral oils
  • a further aim of the present invention is to provide a functional fluid that exhibits improved corrosion inhibition
  • a further aim of the present invention is to provide a functional fluid that exhibits improved anti-wear properties
  • a further aim of the present invention is to provide a synthetic functional fluid that exhibits improved compatibility with water based functional fluids.
  • a functional fluid comprising a water soluble polyalkylene glycol.
  • the polyalkylene glycol preferably has a molecular weight of less than 2,900, more preferably less than 2,000
  • the functional fluid is preferably a metal working functional fluid, more preferably a gear oil.
  • the functional fluid may also be a machine slideway lubricant or hydraulic fluid.
  • the non-amine neutralised, alkyl phosphate acid ester preferably comprises from 1 to 18, preferably from 5 to 9, more preferably 5 to 7, carbon atoms.
  • the non-amine neutralised, alkyl phosphate acid ester preferably comprises a high proportion, preferably greater than 70%, of linear chains of carbon atoms
  • the non-amine neutralised, alkyl phosphate acid ester can also be:
  • the non-amine neutralised, alkyl phosphate acid ester is preferably a pentyl, hexyl. heptyl, octyl or nonyl phosphate acid ester or a mixture thereof.
  • the alkyl phosphate acid ester predominantly contains pentyl or heptyl phosphate acid esters or a mixture thereof.
  • the residues can be easily removed using a reduced energy cleaning process such as a hot or cold water wash, which is cheap and convenient to use when compared to high energy alkali cleaning processes.
  • the non-amine neutralised, alkyl phosphate acid ester is available from, for example, Elf Atochem, Albright and Wilson and Bayer.
  • the polyalkylene glycol will usually have a viscosity at 40°C within the range of 20 to 10,000 centistokes and a viscosity at 100°C within the range of 3 to 2,000 centistokes
  • the polyalkylene glycol may be based on the reaction product of a 1 ,2-ox ⁇ de (vicinal epoxide) with water, alcohol or aliphatic polyhyd ⁇ c alcohol containing from 2 to 6 hydroxyl groups and from 2 to 8 carbon atoms per molecule
  • the polyalkylene glycol is available from Inspec ('BREOX') and Dow Chemicals ('SYNALOX')
  • the functional fluid may also comprise the following usual additives- extreme pressure agents; anti-foaming additives; anti-wear additives, corrosion inhibitor additives; anti-oxidants; metal passivators; and vapour phase corrosion inhibitors
  • Functional fluids comprising water soluble polyalkylene glycols exhibit surface active properties. This presents the formulator with a challenge to provide the same level of corrosion inhibition, anti-wear and extreme pressure properties as obtained with mineral, ester and polyalphaolefin based lubricants.
  • the functional fluid of the present invention preferably comprises: from 0 10 to 99.00%, more preferably 70 to 99%, of polyalkylene glycol, from 0 01 to 5.00%, more preferably 0 10 to 1 00%, of phenolic antioxidant, from 0.01 to 5.00%, more preferably 0.10 to 1.00%, of aminic antioxidant; from 0.01 to 1.00% of benzot ⁇ azole; from 0.005 to 1.00%, more preferably 0.005 to 0.5% of antifoam; from 0.00 to 5.00%, more preferably 0.1 to 1.0%, of polysulphide;and from 0.01 to 5.0%, more preferably 0.15 to 1.0%, of alkyl phosphate acid ester
  • the functional fluid exhibits compatibility with aqueous based metalworking fluids without affecting their function
  • the functional fluid should contain no mineral oil
  • the functional fluid may contain insignificant amounts of mineral oil. Therefore, contamination of metal working fluids with mineral oil, or significant amounts of mineral oil, is avoided, and expensive and time-consuming cleaning processes are not required
  • the polyalkylene glycol based fluid was placed into a blending vessel and the benzotriazole, antioxidant, polysulphide, antifoam and alkyl phosphate were added.
  • the mixture was heated, while mixing, to between 45°C and 50°C to dissolve the benzotriazole and butylated hydroxy toluene (BHT).
  • BHT butylated hydroxy toluene
  • the functional fluid prepared above may be prepared with, for example, the following viscosity grades: 150cSt, 220cSt, 320cSt and 460cSt.
  • the functional fluid prepared in the above example had a viscosity grade of 150cSt.
  • the steel pin corrosion test was carried out in accordance with ASTM D-665B (10% synthetic sea water at 60°C for 24 hours). Examples 1 and 2 gave no rust at 0.35% of alkyl phosphate acid ester. This level of corrosion protection is usually difficult to achieve with polyalkylene glycol based fluid due to surface activity and competition for the metal surface with corrosion inhibitors and antiwear additives.
  • the steel pin corrosion test was carried out in accordance with the ASTM D-665 method with the 10% deionised water or synthetic sea water being replaced with 10% of a 5% solution of a metalworking fluid.
  • the metalworking fluid was CASTROL SYNTILO GX, which is available from Castrol Limited. Further examples were carried out using lloform PS 300 and PS 301 , which are also available from Castrol Limited. Examples 1 and 2 gave no rust when contaminated with these synthetic non-mineral oil-containing, water based metalworking fluids.
  • lloform PS 300 or lloform PS 301 The advantage of using lloform PS 300 or lloform PS 301 is that the metalworking fluid uses the same type of basefluid as in the gear oil. Contamination of the gear oil by the llofrom PS 300 or PS 301 maximises fluid function and minimises stability problems because:
  • Timken OK load test was carried out in accordance with ASTM D-2782.
  • Example 1 gave a load carrying OK load of >90 pounds and when contaminated with 5% lloform PS 300 the OK load was 60 pounds.
  • Example 2 gave an OK load of 45 pounds and, when contaminated with 0.5% lloform PS 300, the OK load was not affected.
