Definitions

  • the present invention relates to non-flammable multiuse aerosol lubricants.
  • This invention relates to an improved aerosol non-flammable composition in the form of a substantially stable water-in-oil emulsion for use in protecting metal from rust and corrosion, penetrating stuck parts, displacing moisture and lubricating almost anything. More particularly, such improved aerosol non-flammable composition consists of water, an oil base, an invert emulsifier, and a preservative.
  • the aerosol delivery system consists of a standard aerosol mechanism with increased stem orifice radius sufficient to create larger than standard droplets in the aerosol to reduce the fiammability profile of the aerosol mist.
  • Multiuse aerosol lubricants are widely known. Generally, such compositions employ hydrocarbons and are flammable. The most widely known and successful of these compounds is marketed under the trademark WD-40 ® . For over 50 years, consumers have used WD-40 ® Multi-Use Product (hereinafter "WD-40 ® ”) to protect metal from rust and corrosion and for penetrating lubrication. WD-40 ® protects and lubricates effectively, in part, because it so effectively displaces water. The formulation for WD-40 ® is a trade secret but is generally understood to consist of hydrocarbons and other proprietary ingredients. It does not contain water. There has long been a need for non-flammable multiuse aerosol lubricants.
  • WD-40 ® Multi-Use Product
  • This invention has found surprisingly that when an invert emulsion made with a synthetic ester base oil and a compatible invert emulsifier is delivered through an aerosol apparatus that creates certain larger than standard droplets it creates a non-flammable multiuse lubricant aerosol.
  • a preservative is included in the composition to prevent the growth of bacteria, yeast, and molds that would interfere with the creation and stability of the emulsion.
  • the improved water-in-oil aerosol non-flammable multiuse lubricating composition appears to be an improvement over the prior art lubricating compositions because of its improved combination of lubrication, corrosion and rust prevention, water displacement, and fire resistance.
  • the improved multiuse composition is in the form of a substantially stable water-in-oil emulsion consisting of 10% to 20% by weight of a liquified, normally gaseous, propellant and 80% to 90% of a base consisting essentially of by weight:
  • Aerosol apparatus for delivering the formulation in a stable non-flammable form. Aerosols of the current invention created using a standard stem sizes, however, are flammable.
  • the current invention uses stems and actuators with increased radiuses or other components to create larger droplets in the aerosol, which in turn creates a non-flammable aerosol.
  • a stem orifice of 0.013" to 0.025" is preferable.
  • a multiuse composition in the form of a substantially stable water-in-oil emulsion consists of 13% Honeywell's Solstice (HFO-1234ze) propellent by weight and 87% to a base consisting essentially of by weight:
  • the aerosol apparatus for delivering the formulation in a stable non-flammable form consists of standard aerosol components with a stem with increased orifice of 0.020" and two entry ways for uptake of the base liquid.
  • Hypermer 2524 is an oligomeric ester emulsifier for use in the manufacture of inverse polymer emulsions. It is compatible with synthetic esters such as Priolube LL- 564 as an inverse emulsifier. It is a proprietary product manufactured and sold by Croda International Pic.
  • Priolube LL-564 is a low viscosity synthetic ester. It is a proprietary product manufactured and sold by Croda International Pic.
  • Reputain B-30 is a preservative that contains 2-bromo-2-nitropropane-l,3-diol (30%), Propylene glycol (57.5 - 62.5%), and Water (7-10%).
  • the above composition has shown surprisingly good lubricating and anticorrosion properties while maintaining non-flammability in both the liquid and aerosol form.
  • the invert emulsion was the only formulation that had lubricating and anticorrosion properties similar to the market leader WD-40 ® , while remaining nonflammable in both liquid and aerosol form.
  • Synthetic Emulsion - This is a proprietary synthetic metal working fluid formulation provided by Croda International Pic.
  • GPL and PFPE - This is a formulation of chlorinated hydrocarbons
  • PFPE perfluoropolyether
  • Vertel XF (1,1,1,2,2,3,4,5,5,5- Decafluoropentane) is a proprietary hydrofluorocarbon fluid used as a solvent and vapor degreasing equipment for cleaning, rinsing, and drying. Vertel XF is supplied by Chemours.
  • GPL-105 is a clear, colorless perfluoropolyether oil that is nonflammable and long-lasting. On a weight basis, GPL-105 contains 21.6% carbon, 9.4% oxygen, and 69.0% Fluorine. It is sourced from Chemours.
  • KDP and PFPE - This is also a formulation of chlorinated hydrocarbons and
  • PFPE perfluoropolyether
  • Phosphate Ester - This is a product sold by Exxon under the name Hyjet V. It is marketed as a fire-resistant hydraulic fluid based on phosphate esters. Its chemical composition is commercially described as 70-80% tributyl phosphate, 10-20% phenol, isopropylated, phosphate, 5-7% aliphatic epoxide, and 0.1-1% 2,6-Di-Tert-Butyl-P- Cresol.
  • Reolube 46B is sold by Chemours and marketed as a fire-resistant hydraulic fluid. It is essentially 100% Phenol, isobutylenated, phosphate, with less than 25% of phenols triphenyl phosphates.
  • the invert emulsion was generally comparable or better than most of the other potential non-flammable multiuse lubricators. Three tests were performed on the formulations to determine their relative abilities to lubricate under varying conditions. Those tests and results are described below.
  • This test is commonly known as the Four Ball Wear and measures the wear protection of a test fluid.
  • Three steel balls are clamped together and covered with the lubricant to be evaluated.
  • a fourth steel ball is pressed with force into the top cavity formed by the three lower balls.
  • the temperature of the test lubricant can be regulated and then the top ball is rotated at 1200 rpm for 60 minutes.
  • Lubricants are compared by the average of the measure (in mm) of the scar worn into the three lower balls. Good results are less than 1.0 mm with excellent results being around 0.5 mm.
  • Anti-wear fluids will reduce the amount of metal lose due to friction during a metalworking process or metal to metal contact.
  • ASTM D-3233 Measurement of Extreme Pressure Properties of Fluid Lubricants (Falex Pin and Vee Block Methods " ).
  • This test measures the load-carrying properties of a lubricant by rotating a steel pin at 290 rpm against two stationary V-blocks immersed in the lubricant sample. Load, in 250 foot pound increments, is applied to the V-blocks by a ratchet mechanism. The load is increased every minute until failure occurs as indicated by breakage of the shear pin or test pin, or inability to increase or maintain the load on the ratchet wheel. Results are reported as pounds with 4,500 being the maximum that can be detected. An extreme pressure fluid will maintain its lubricating properties as pressure and temperature increases.
  • ASTM D-5620 Evaluating Thin Film Fluid Lubricants in a Drain and Dry Mode.
  • test fluid is deposited on the pin and V-blocks and allowed to drain for 1 to 4 minutes.
  • the steel pin is rotated at 290 rpm against two stationary V-blocks and a load of 300 foot pounds is applied. If after 60 minutes, there is no failure, the load is increased to 500 foot pounds. Failure is when the steady state torque is interrupted by a sharp increase or spike in the torque, breakage of the shear pin, or failure to maintain the load. Results are reported in minutes at load pounds.
  • invert emulsion was markedly better than most of the other potential nonflammable multiuse lubricators. Two tests were performed on the formulations to determine their relative abilities to prevent corrosion and rust. Those tests and results are described below.
  • ASTM B-l 17 Salt Spray iFog ⁇ Apparatus.
  • This test is used to measure the level of corrosion protection provided by a test fluid.
  • Cold rolled steel panels, with surface prepared by sand blasting, are treated with the fluid by dipping or spray, allowed to drain for 2 hours, then placed in the salt spray cabinet that contains a fog of 5% salt (NaCl) water solution at 35°C (95°F). Panels are left in the closed cabinet for the entire test period; we typically use a 72 hour period.
  • FTM-3007 Water Displacement.
  • This test is used to measure the ability of a fluid to displace water on a metal surface and then provide corrosion protection.
  • Cold rolled steel panels, with surface prepared by sand blasting are immersed in deionized water and then immersed in the test fluid just prior to being place in a static humidity chamber (25°C and 50% humidity) for one hour. The procedure is repeated but using the test fluid after a 10% level of water has been added and mixed with it. Results are reported as % visible corrosion for both the as is and the contaminated fluid.
  • the invert emulsion was the only potential non-flammable multiuse lubricant with superior lubrication and anticorrosion properties that was also non-flammable in an aerosol form.
  • the Invert Emulsion was tested for flammability using a straw connected the actuator and without. Three tests were performed on the formulations to determine their relative flammability profile. Using the larger stem orifice radius reduced the flammability profile of the invert emulsion. Those tests and results are described below.
  • a spray can is placed in a holding device 15cm from an open flame source set at a height of 5 cm.
  • the spray can is discharged for 5 seconds and the flame extension is measured.
  • the operator can then determine if a flashback exists by observing if a flame travels backwards toward the spray can.
  • a spray can is discharged towards an open flame starting at a distance of 60 cm. The distance is shortened incrementally until a sustained ignition is observed.
  • a spray can is discharged into a test vessel (55 gallon drum) containing a burning candle.
  • a timer is started at the time the can was discharged in order to determine the time elapsed before ignition, if any.
