Definitions

  • This invention relates to a surfactant mixture for use in preparing industrial lubricants e.g. hydraulic or machine tool cutting oils comprising clear homogenous microemulsions.
  • the present invention seeks to overcome the above mentioned problems by providing a surfactant composition which allows the formulation of oil - water mixtures which are microemulsions of water in oil and are true solutions or behave as such.
  • solution herein describes any mixtures which are clear and homogenous.
  • behave as such means that the mixture has substantially the same stability as a solution.
  • the present invention accordingly provides a composition for use in combining oil and water as a stable solution (emulsion, preferably a microemulsion) which composition comprises (a) a fatty acid amine ethoxylate (b) a C 6 -C 15 alcohol ethoxylate and optionally (c) a tall oil fatty acid amine.
  • compositions are combined together in quantities that allow the formation of microemulsions on addition to the appropriate oil and water mixture.
  • composition may comprise additional components. These have been found to include sorbitan esters, mono and di - glycerides of fatty acids, polymeric emulsifiers containing fatty acid side groups, polyimides and substituted polyimides such as poly isobutenylsuccimide. Other surfactant types will be apparent to those versed in the art.
  • Preferred components of the surfactant composition are all readily available commercially.
  • the parts by volume in each case being relative to the total volume of the composition.
  • the composition of the present invention comprises the tall oil fatty acid amine.
  • This component may be used to impart (further) stability to the composition of the present invention.
  • the minimum quantity of the surfactant composition required is dependant upon the water content of the desired microemulsion and the base oil type being used. For example, 80 parts of a naphthenic base oil (Shell, solvent pale 60) was emulsified with 20 parts of water such that a microemulsion was obtained. This was achieved with the addition of 20 parts of the surfactant composition. Using a different base oil, based upon a paraffinic type (Shell, 130 solvent neutral), with the same quantities of water and oil required 30 parts of the surfactant composition to form a microemulsion.
  • a naphthenic base oil Shell, solvent pale 60
  • the surfactant is added to the oil water mixture with gentle mixing until a clear homogenous microemulsion is obtained.
  • microemulsions will have many applications in the industrial lubricants market. It may be necessary for certain applications to incorporate other additives i.e. to give extreme pressure protection for higher temperature applications. These applications and additional additives will be apparent to those skilled in the art.
  • composition suitable for combining 70 parts of a paraffinic type base oil (Shell 130 solvent neutral) with 30 parts of water was prepared by adding the following components in the quantities stated:
  • Example 2 The components were gently mixed to form a homogenous solution.
  • Example 2 The components were gently mixed to form a homogenous solution.
  • Example 1 30 ml of water was added to 70 m of Shell 130 solvent neutral in a clear glass container.
  • the surfactant composition of Example 1 was introduced to the oil and water from a burette. After each addition of surfactant the resulting solution was mixed. This continued until a clear homogenous solution was observed. The resulting solution remains stable for more than one year.
  • Example 1 20 ml of water was added to 80 ml of Shell solvent neutral in a clear glass container.
  • the surfactant solution of Example 1 was introduced into the oil and water as in Example 2. The resulting solution remains stable for more than one year.
  • Example 2 The solution obtained in Example 2 was used to determine its corrosive properties on mild steel. This was done by placing a piece of mild steel in the solution and observing the formation of rust. No corrosion has been observed after 6 months.
  • composition of the present invention is effective in preventing such growth.
  • Any growth of this algae was to be monitored by any colour change of the solution as the algae produce a green growth in macroemulsions. No micro-organism growth was observed after 6 months. It is believed that the compositions of the present invention prevents any micro-organism growth because the water droplets in the solution containing the surfactant composition are smaller than the micro-organisms and so there is insufficient oxygen for the algae to grow.
  • Microemulsions have been prepared in the following base oil types i) paraffinic ii) naphthenic iii) linear alpha olefins iv) ester type base fluids
  • a microemulsion using linear alpha olefin was prepared as in Example 2 using 35 parts of the surfactant composition. This was then tested using the lubricant industry standard IP287 to determine the potential of the solution to promote corrosion. No corrosion has been observed using this or indeed any other prepared solution.
  • Example 8 The solution from Example 8 was doped with a heavily contaminated soluble oil. The resulting solution was then tested using an agar dipslide to monitor bacterial growth within the solution. No culture or bacterial growth was observed after 168 hours at 35°C. It is generally recognised that bacteria will be observed on the culture medium after 72 hours when held at 35°C.
  • a hydraulic oil was prepared using the microemulsion from example 2 with an anti- wear additive based on sulphur. This was added at a rate of 5 % v/v. A further hydraulic oil was prepared using the same base oil and sulphur additive. Both oils were then tested for their anti-wear properties using the Reichert testing apparatus. The microemulsion showed a reduced weight loss compared to the standard oil of 10 % .
  • a gear oil has been prepared using a commercially available oil (Mobil Glygoyle HE460) and the composition of Example 1.
  • the resulting oil has shown improved coolancy with no loss in lubricity using standard anti-wear tests i.e. four ball tests.
  • a grinding oil was prepared using a linear alpha olefin base oil with the composition of Example 1. This was tested against a standard grinding oil and was shown to be of superior cooling ability with no loss in lubricity.
