Definitions

  • Soluble-oil emulsions are well known as cutting fluids.
  • the term "soluble-oil” although used throughout the industry is, in fact, a misnomer because the constituents are not soluble in water.
  • the soluble-oils are basically mineral oils blended with emulsifiers and other additives which, when added to water and stirred, form an oil-in-water emulsion.
  • the emulsion allows the good cooling properties of water to be utilised in the metal working process whilst the oil and additives provide lubrication and corrosion inhibiting properties.
  • the present invention relates to a soluble-oil which is relatively stable without the need for a conventional coupling agent.
  • the alkali metal or alkaline-earth metal of the alkyl benzene sulphonate is preferably potassium or calcium or more preferably sodium.
  • the alkyl group is preferably derived from polypropylene.
  • the alkali or alkaline-earth metal alkyl benzene sulphonate may be produced by known methods from synthetic sulphonic acids.
  • the molecular weight of the compound is from 400 to 520. A high molecular weight improves the corrosion inhibiting properties of the soluble oil whereas a low molecular weight improves emulsion stability and so the choice of molecular weight involves a compromise. Mixtures of alkyl benzene sulphonates may be used.
  • the fatty acid diethanolamides are preferably formed by the reaction of diethanolamine with naturally occurring fatty acids having from 12 to 20 carbon atoms.
  • the fatty acids may be saturated or unsaturated but are preferably unsaturated.
  • the mixed alkanolamine borate comprises the reaction products of more than one alkanolamine with boric acid.
  • the alkanolamines may be selected from monoethanolamine, diethanolamine, triethanolamine, N,N dimethyl ethanolamine.
  • a preferred combination of alkanolamines is mono- and di-ethanolamine.
  • the polyisobutene succinimide is preferably overbased with excess amine and preferably has a molecular weight of from 1000 to 3000.
  • the soluble-oil formulation also preferably contains a small amount of distilled water e.g. from 0 to 2% by weight of the total weight of the soluble-oil.
  • the distilled water improves the stability of the blend.
  • a defoaming agent such as a Friedel Krafts wax may also be included in the soluble oil.
  • a suitable wax is SASOL wax SH 105 supplied by Weber.
  • the amount of defoaming agent is preferably in the range 0-0.05% by weight of the total weight of the soluble-oil.
  • a biocidal soluble-oil If a biocidal soluble-oil is required, a conventional biocide may be included in the formulation.
  • the optional components of the soluble-oil are included in the composition in place of some of the mineral oil.
  • base oils designated 100 to 500 solvent neutral have been found to be particularly suitable, i.e. paraffinic oils typically having kinematic viscosities at 40°C in the range 12 to 100 cSt.
  • the soluble-oil according to the present invention is relatively stable and when mixed with water readily forms an emulsion which may be used in a number of metal working operations e.g. cutting, drilling and grinding.
  • the emulsion has a water to soluble-oil ratio of from 10:1 1 to 40: although higher and lower dilutions may be useful in certain applications.
  • the sodium alkyl benzene sulphonate had an average molecular weight of 440 and was used as a 60% by weight solution in a paraffinic mineral oil.
  • the fatty acid diethanolamine was oleic acid diethanolamide and was approximately 25% overbased with excess diethanolamine.
  • the mixed alkanolamine borate was a mixture of boric acid, monoethanolamine and diethanolamine in the approximate weight ratio 30:33:35.
  • the polyisobutene succinimide was formed by the reaction between a polyisobutene having a molecular weight of approximately 1000, succinic acid anhydride and diethanolamine and was overbased with a small excess of N,N dimethyl ethanolamine.
  • a test rig was used to evaluate the microbial degradation of the soluble-oil emulsions in a simulated workshop operation.
  • the rig comprised a reservoir for the cutting fluid and an air lift pump to transfer the fluid from the reservoir to a funnel containing metal cuttings, the funnel being mounted over the reservoir so that the fluid drained back into the reservoir.
  • Duplicate samples of Formulation A diluted with mains tap water in the ratio of water to oil of 20:1 were tested in the test rig.
  • An inoculum prepared from a mixed culture of fungi and bacteria originating from a spoiled cutting oil emulsion was added to the test samples so that an initial total viable count of approximately 10 6 micro-organisms per millilitre of emulsion was obtained.
  • the emulsion had not evolved H 2 S or encouraged yeast, mould or fungal growth.
  • the total viable bacteria count remained at approximately 10 6 organisms per millilitre of emulsion throughout the test.
  • the strength of the emulsion was relatively constant throughout the test and the pH which was initially 9.5 fell to around 8.5 after 12 days and then remained at this value for the remainder of the test period.
