Description
United States atent C 2,913,411 METAL WORKING LUBRICANT Knapel F. Schiermeier, Alton, Ill., assignor to Shell Development Company, New York, N.Y., a corporation of Delaware No Drawing. Application June 7, 1957 Serial No. 664,147 8 (Ilaims. (Cl. 252-333) This invention pertains to multifunctional transparent stable liquid petroleum-water solutions particularly suitable as metal working fluids which have good rust preventive and load carrying properties.
It is apparent from the art that transparent metal working lubricants having good rust inhibiting and load carrying properties are highly desirable because they enable the operator to observe the progress of the work without stopping the operation of the machine and to do more accurate work under cleaner conditions. Also, increased production results and less handling of the work piece reduces possibility of corrosion. However, known transparent fluids of this type which normally contain as the essential active ingredient large amounts of synthetic detergents and a plurality of rust inhibitors such as nitrite, phosphates, amines, etc. are expensive to prepare. They are also generally unstable, sensitive to water hardness and are generally poor with respect to load carrying properties.
It is a principal object of this invention to prepare inexpensive multi-functional transparent liquid petroleum water solutions. Another object of the invention is to prepare a stable transparent mineral oil-water solution for use as a metal working fluid which is insensitive to either soft or hard water, which is non-corrosive, and has good load carrying properties.
It has now been discovered that a liquid petroleum (fuel or lubricating oil)-water solution of this type for use per se or for compositing with water and which results in an excellent transparent coolant and lubricant useful as cutting, grinding, threading, cooling and other industrial uses is provided by a concentrate consisting essentially of a liquid petroleum-water solution containing minor amounts of each, of an oil-soluble alkali metal (Na or K) petroleum sulfonate, an alkali metal (Na or K) ricinoleate or alkali metal (Na or K) salt of castor oil fatty acids and a water soluble mass action or salting out agent such as an alkali metal (Na or K) carbonate. If desired, to the concentrate or final composition can be added a minor amount of a bactericidal or germicidal agent preferably of the phenolic type such as are sold commercially by Dow Chemical Co. under the trade name Dowicide A (sodium o-phenyl phenate) and/or a silicone polymer anti-foaming agent such as are sold by Dow Corning Co. as Anti-foam A and are described in the November 1948 issue of the Journal Industrial Hygiene and Toxicology.
Of the above sodium or potassium compounds the sodium compounds are preferred.
The alkali metal petroleum sulfonates are well known in the art and are prepared by reacting a mineral oil with concentrated or fuming sulfuric acid to form oilsoluble sulfonic acids which are then recovered by treatment with an alkali metal base such as sodium hydroxide followed by extraction. These oil-soluble soaps are available as 30% to 70% concentrates in mineral oil.
The liquid petroleum employed in the concentrate may be a light petroleum hydrocarbon fraction in the viscosity range of from about 40 to about 200 SUS at 100 F., preferably from about 60 to about 120 SUS at 100 F. Petroleum fractions of this type can be derived from any type of crude such as asphaltic, naphthenic or paratfinic 2,913,41 l Patented Nov. 1 7, l 959 ice type crudes and include gasoline, fuel oil and lubricating oils. It is preferred to use a light lubricating oil such as a 100 SUS at 100 F. pale oil.
Typical general formulation of the concentrate composition of this invention is as follows:

A transparent water soluble concentrate consisting essentially of a mineral oil-in-Water solution, wherein the mineral oil has a viscosity in the range of from about 40 to about 200 SUS at 100 F., the oil is 10-30% by weight of the solution and the water is 50-60% of the solution and the concentrate contains from about 5% to about 25% of an oil-soluble alkali metal petroleum sulfonate, from about 4% to about 10% of an alkali metal compound selected from the group consisting of alkali metal ricinoleate and alkali metal salt of castor oil fatty acids and from about 0.1% to about 2% of an alkali metal carbonate.
2. A transparent water soluble concentrate for use in aqueous cutting fluids consisting essentially of a mineral oil-in-water solution, wherein the mineral oil has a viscosity in the range of from about 40 to about 200 SUS at 100 F., the oil is -25% by Weight of the solution and the water is 5055% by weight of the solution, the concentrate contains from about 10% to oil-soluble sodium petroleum sulfonate, from about 4% to about 10% of sodium ricinoleate and from about 0.3% to about 1% of sodium carbonate.
3. A transparent water soluble concentrate for use in aqueous cutting fiuid consisting essentially of a light mineral oil-in-water solution, wherein the mineral oil has a viscosity from about 60 to about 120 SUS at 100 F., the oil consisting of from about 10 to about of the solution which also contains from about 10% to 20% of oil-soluble sodium petroleum sulfonate, from about 4% to about 10% of sodium ricinoleate, from about 0.3% to Sodium petroleum sulfonate percent weight 20 Ricinoleic acid do 6 Sodium hydroxide 0.6 Sodium carbonate 0.5 Sodium o-phenyl phenate 0.3 Silicone polymer p.p.m 30 Pale oil SUS at 100 F.) perccnt weight 21 Water Balance References Cited in the file of this patent UNITED STATES PATENTS 2,079,051 Sullivan et al.
