Description
United States Patent 3,539,514 CORROSION INHIBITOR AND LUBRICANT Arthur Frank Strouse, 2622 Swede Road, Apt. E18, Norristown, Pa. 19401 No Drawing. Filed Aug. 1, 1967, Ser. No. 657,528 Int. Cl. Cm N54 US. Cl. 25240.5 2 Claims ABSTRACT OF THE DISCLOSURE The corrosion inhibitor and lubricant of the present invention contains from 0.1 to 50 Weight percent of barium soaps of organic acids derived from the partial liquid phase oxidation of petroleum fractions, which acids have a mean molecular weight of about 400, and from 0.1 to 50 weight percent of di-Z-ethylhexyl sebacate.
The present invention is directed to a corrosion inhibitor and lubricant, and more particularly, a corrosion inhibitor and lubricant which can function at both high and low temperatures, and which can be impregnated into thermoplastics, such as nylon and Teflon.
There has been a long felt need for a corrosion inhibitor and lubricant which will protect metal surfaces against rust and pitting under atmospheres of high humidity, or exposure to water. Particularly, there has been a need for such a corrosion inhibitor and lubricant which is capable of functioning properly at extreme temperatures, such as temperatures far below 0 C. and temperatures far above 100 C.
In addition, such corrosion inhibitor and lubricant should be resistant to washing, as by Washing with soap and water, even when applied to highly polished metal surfaces.
Other desirable properties of such corrosion inhibitor and lubricant are non-conductivity, freedom from static electricity attraction of dust and lint, freedom from gumming and caking, high residual lubricity, freedom from destruction by exposure to sulfur, relatively low volatility, and high flash point characteristics, etc.
The prior art has attempted to produce corrosion inhibitors and lubricants having all of the aforesaid desiderata by combining a large number of additives into a homogeneous mixture and drawing from the specific property of each additive. This has not proven satisfactory both because of incompatibility problems between the additives; loss of additives from the mixture on storage and in usage; and development of adverse chemical reactions among the components on standing and in usage.
This invention has as an object the provision of a novel corrosion inhibitor and lubricant, which will not attract moisture or dust or dirt or lint to a metal surface to which it is applied; will penetrate into highly polished surfaces; will Withstand exposure to severe temperature extremes; has a relatively high residual lubricity; is relatively free from gumming and oak-ing; is resistant to attack by sulfur; is non-c0nducting; and has good nonflammable and flash point characteristics.
Another object of the present invention is the provision of a novel corrosion inhibitor and lubricant containing a relatively small number of components, which components are compatible with each other over broad concentration ranges.
A still further object of the present invention is the provision of a novel corrosion inhibitor and lubricant which is relatively inert to paints, varnishes, and other coatings, and which may be incorporated therewithin.
A still further object of the present invention is the provision of a corrosion inhibitor and lubricant which may be impregnated into thermoplastics, such as nylon and Teflon, and which will confer many of its desirable properties thereon.
Other objects will appear hereinafter.
The present invention comprises from 0.1 to 50 weight percent of di-Z-ethylhexyl sebacate, and from 0.1 to 50 weight percent of a mixture of barium soaps of organic acids derived from the partial liquid phase oxidation of petroleum fractions, which acids have a mean molecular weight range of about 400, plus or minus 40.
Preferably, the compositions of the present invention comprise from 90 to 98 weight percent of di-2-ethylhexyl sebacate and from 2 to 10 weight percent of a mixture of barium soaps of organic acids derived from the partial liquid phase oxidation of petroleum fractions, which acids have a mean molecular weight range of about 400, plus or minus 40.
The barium soaps used in the present invention are prepared in accordance with the methods described in United States Letters Patents 1,690,768, 1,690,769 and 1,768,523. A suitable commercially available barium soap mixture of the aforesaid type is designated Alox 2028 of Alox Corporation, 3943' Buffalo Ave., Niagara Falls, NY. The physical properties of Alox 2028 are as follows:
Acid number (ASTM-D-9745 8T)-35. Saponification number (ASTMD9462)-6l-69. Specific gravity at F. 0.95.
Weight per gallon7.9 lbs.
Flash point (O.C.}-330 F. (min.)
Melting point (ASTMD-l27)95 F.
The compositions of the present invention may be prepared by bonding the di-Z-ethylhexyl sebacate and the Alox 2028 together at room temperature with vigorous agitation.
While the aforesaid mixtures of di-2-ethylhexyl sebacate and the Alox 2028 comprise excellent corrosion inhibitors and lubricants without the addition of any further additives, the present invention contemplates homogeneous mixtures which include additives such as organic titanates, such as tetraisopropyl titanate; molybdenum additives, such as molybdenum disulfide, etc.
The compositions of the present invention may be incorporated in paints, varnishes, finishes, and other protective coatings, to the improvement of such coatings. This is preferably accomplished by having the corrosion inhibitor and lubricant of the present invention in the non-aqueous media, such as petroleum oils and solvents, fatty oils, greases, waxes, or other organic solvents or mixtures of the above, as are used as the vehicle for such paints and the like.
The corrosion inhibitor and lubricants of the present invention may be incorporated into thermoplastics, such as nylon, and Teflon, to confer improved properties thereon.
The present invention may be applied directly to a metal surface in its concentrated form, namely a mixture containing from 0.1 to 50 weight percent of each of the two components. In the alternative, the corrosion inhibitor and lubricants of the present invention may be dissolved in diluents, or otherwise carried in vehicles and applied to a metal surface as such. In particular, the corrosion inhibitors and lubricants of the present invention may be dispensed as an aerosol, and they are entirely compatible with conventional aerosol propellants, such as the Freons.
In order to illustrate the present invention, the following example was prepared:
EXAMPLE A homogeneous mixture of Alox 2028 and di-Z-ethyl- 3 hexyl sebacate was prepared at room temperature. This mixture had the following physical properties:
AppearanceGold translucent fluid Viscosity:
460 cps. (-20- C.)
22 cps. (23 C.)
4 cps. (100 C.) Density7.61 lbs. per gal. (22 C.) Specific gravity-.912 (room temp.) Freezing pointBelow 112 F. Flash pointAbove 400 F.
The aforesaid composition proved an excellent corrosion inhibitor and lubricant for a wide variety of metals. By way of example, the following tests were performed:
Cold roll panels to which the aforesaid mixture had been applied were placed in 100 percent humidity chambers at 212 F. for 48 hours. After this period of time, no rust formation was noted. The panels were then subjected to a thorough washing with soap and water, and again placed into the humidity chamber for an additional 48 hours in 100 percent humidity at 212 F. It was found that such rust that did form was readily removed by brushing.
The aforesaid mixture was used as a lubricant to fill a gear *box containing high carbon steel gears. After 16 days of operation in such gear box, the gears were placed into a humidity chamber and subjected to 100 percent humidity at 212 F. for 48 hours. No rust formation was noted.
The above lubricant was subjected to the following testing to demonstrate its extreme resistance to temperature changes:
Six ounces of the above lubricant was brought from 72 F. to its vapor point. The vapors were then superheated ot the temperature of molten iron (iron triad) 1535 C. This test was performed at standard temperature and pressure, oxygen was continuously present.
The molten iron was heated by means of an electric furnace. This molten iron was arrested in a crucible. Drops of the lubricant were fed, one by one, into the molten iron. The vapors were captured by means of a hood, which had an apex leading through coils cooled by a Water tube system which in turn brought the vapors back to their liquid state. This process was repeated 500 times without the addition of additional material.
The lubricity of the lubricant was then measured by using a 250-pound weight, stimulated by a known force. The distance this weight traveled under the stimulated force was compared with the distance the same weight traveled using the same force with virgin lubricant. At that time it was determined that the material had not lost any of its lubrication value since the force and distance traveled did not change.
After the previously mentioned tests the compound under microcsopic examination showed no signs of deterioration. Loss in the amount of the fluid was within a reasonable amount, within a range of .5 (5/ of one ounce.
Six ounces of the above lubricant was taken to l95 C. with liquid nitrogen, and reheated to room temperature immediately. This process was repeated 500 times at normal temperature and pressure. At that time it was found that the material had not lost any of its lubrication value, and the compound under microscopic examination showed signs of no deterioration.
The lubricant prepared by the above example has been dissolved in the following solvents and may be applied as. a solution from the following solvents or like solvents:
4 kerosene, naphtha, benzene, toluene, chlorinated and fluoridated hydrocarbons, acetone, ethyl ether, etc.
Mixtures of the aforesaid material have been prepared with from 0.5 to 5.0 weight percent molybdenum disulfide, from 0.2 to 20 weight percent of te-traisopropyl titanate; and from 0.2 to 20 weight percent of the Du Pont fluorcarbon pelomar dispersion designated Vydax AR, whose properties are described in Du Pont Industrial Chemicals Information Bulletin 16. In each case, the beneficial properties of the additive were retained in the composition.
An aerosol formulation was prepared from 0.004 gram of Alox 20 28, 0.080 gram of di-2-ethylhexyl sebaca-te, and .916 gram of the chlorinated hydrocarbon designated Chlorothene of American Mineral Spirits. This aerosol formulation was dispensed using conventional aerosol propellants.
Cold roll panels spray-coated with the aforesaid formulation and exposed for 2% months to 100 percent humidity at 100 F. exhibited no rust formation. Similar cold roll panels which were spray-coated and exposed to ambient outside environment for 24 days, during which period 15 days had rain, likewise exhibited no rust formation. Satisfactory lubrication was obtained using the aforesaid formulation on roller bearings that were exposed to a constant pelting by a solution used in the manufacture of television screens. A single aerosol spray application of the formulation enabled the hearings to function without failure for a period of 12 days.
The present invention may be embodied in other specific forms without departing from the spirit or essential attributes theerof and, accordingly, reference should be made to the appended claims, rather than to the foregoing specification as indicating the scope of the invention.
