Non-flammable aerosol multiuse invert emulsion lubricant

Abstract

Stable water-in-oil emulsions suitable for use as fire-resistant aerosol multipurpose lubricants. The water-in-oil emulsion comprises a synthetic ester base oil, compatible invert emulsifier, water, and a preservative. The aerosol apparatus employs a larger than standard stem orifice to produce a non-flammable aerosol.

We claim: 
     
         1 . An aerosol lubricating composition comprising by weight:
 45% to 55% of water;   5% to 10% water-in-oil emulsifier compatible with a synthetic ester base oil;   35% to 45% of synthetic ester base oil; and   a preservative.   
     
     
         2 . The composition of  claim 1  in which the water-in-oil emulsifier is an oligomeric ester emulsifier. 
     
     
         3 . The composition of  claim 1  in which the base oil is a low viscosity synthetic ester. 
     
     
         4 . The composition of  claim 1  in which the water is deionized. 
     
     
         5 . The composition of  claim 1  in which the composition is provided in an aerosol delivery mechanism with a stem and actuator of sufficient width radius to a create non-flammable mist. 
     
     
         6 . The composition of  claim 5  in which the stem width radius is between 0.013″ to 0.025″. 
     
     
         7 . The composition of  claim 5  in which the stem width radius is 0.020″. 
     
     
         8 . The composition of  claim 1  in which the composition is mixed with a non-flammable propellent in a ratio of 10% to 20% propellent and 80% to 90% composition. 
     
     
         9 . The composition of  claim 1  in which the composition is mixed with a non-flammable propellent in a ratio of 13% propellent and 87% composition. 
     
     
         13 . The composition of claim  11  in which the propellent is Honeywell's Solstice (HFO-1234ze).
