Description
Patented May 30, v1939 UNITED STATES PATENT OFFICE LUBRICANT No Drawing.. Application September 10, 1937, Serial No. 163,245
34 Claims.
This invention relates to improvements in lu-' bricants, and in particular to lubricants having improved extreme pressure characteristics and having corrosion inhibiting properties when employed in the presence of hard metal alloy bearmgs.
The development of internal combustion engines having higher compression ratios, increased acceleration, and increased speed characteristics has made it desirable to use motor oils which possess extreme pressure properties. The improvements in the internal combustion engines have also necessitated the replacement of soft metal bearings, such as babbitt, by hard metal 5 alloy bearings of the cadmium-silver type. The improved oil refining methods, such as the drastic acid treatment and/or the solvent extraction processes, to produce oils of improved viscosity indices, which have been developed almost contemporaneously with the introduction of the hard metal alloy bearings, resulted in a new problem in the lubrication of bearings of these types in that these highly refined oils have been found to be corrosive to bearings of the hard metal alloy type. An effective motor oil should therefore possess extrem; pressure characteristics and be non-corrosive to bearings of the hard metal alloys.
Most of the so-called corrosive inhibitors of hard metal alloys do not possess extreme pressure lubricating properties, and vice versa, the known compounds which impart extreme pressure lubricating properties to lubricants do not necessarily inhibit corrosion of hard metal alloys.
It is therefore one of the principal objects of the present invention to provide a material which when added to lubricants will inhibit the corrosion of hard metal alloys and impart extreme pressure lubricating characteristics to the lubri- Q cant.
We have found that extreme pressure lubricating properties and the property of inhibiting corrosion of alloy bearings of the cadmium-silver type can be imparted to lubricating oils by 3 adding thereto up to 5% but preferably from about 0.05% to about 2% of an organic titanate selected from the group of compounds having the general formulas:
in which R is a radical selected from the group consisting of alkyl, aryl, hydroaryl and aralkyl radicals, R is a radical selected from the group consisting ofhalogenated alkyl, halogenated aryl,
and halogenated aralkyl radicals, X is an element selected from the group consisting of oxygen and sulfur, Y is a halogen and n is an integer selected from the group of whole numbers consisting of 1, 2 and 3. The compounds illustrated by the 5 foregoing general formulas are also known as the hydrocarbon titanates, hydrocarbon thiotitanates, hydrocarbon meta titanates, hydrocarbon meta thiotitanates, halo-hydrocarbon titanates, halo-hydrocarbon thiotitanates, halo-hydrocarbon meta titanates, halo-hydrocarbon meta thiotitanates, hydrocarbon halo-titanates, hydrocarbon halo-thiotitanates, halo-hydrocarbon halo-thiotitanates, halo-hydrocarbon halo-titanates.
As examples of specific compounds coming within the foregoing general classifications may be mentioned:
Butyl titanante Ti(0C4H9) 4 Dicyclohexyldichlor titanate Cyclo CsH11O)2TiCl2 Amyl trichlor titanate CsHnOTiCls Amyl trichlor thiotitanate C5H11STiC13 Chlorpropyl titanate (C1C3HsO)4Ti Dichlor butyl titanate (ClzC4H7O) 4Ti 4O Chlorpropyl chlortitanate (C1C3HeO)3TiC1 Chlorpropyl thiotitanate (ClCzHeS) 4T1 Chlorphenyl titanate (C1CsH4O)4Ti The load carrying capacity of these organic titanates was determined on the Almen testing machine which is described by Wolf and Mougey in their paper on Extreme pressure lubricants given at the 13th annual meeting of the A. P. I. at Houston, Texas, November 17, 1932. Briefly, it consists of a test pin or journal made of A inch diameter drill rod which can be rotated in a /2 inch long split bushing with provisions for loading the bearing thus formed by clamping together the two halves of the split bushing. Provision is also made to measure the torque rehave been added to the loading device or when seizure occurs, whichever happens first.
A sample of an S. A. E. 20 lubricating oil and another sample of the same oil containing 0.5% butyl titanate were submitted to tests on the Almen machine with the following results:
Almen test Oil Almen test Pounds 6 to 8 20 to 24 ControL.-. Control +0.5% butyl titanate The load carrying capacity of extreme pressure lubricants may be also determined on the socalled Tlmken testing machine described in the S. A. E. Journal, vol. 28, No. 1 (January, 1931) Page 53, and in U. S. Patent 1,990,771.- Testing samples of the same oils used on the Almen machine, on the Timken machine the following results were obtained:
Timl'cen test Oil Load at which seizure occurred Pounds Contrnl 8 Control +0.5% butyl titanate 40 The data obtained by these tests demonstrate that the extreme pressure properties of a lubricant containing a small amount of an organic titanate is from about 300% to about 500% better than the same lubricant containing no organic titanate.
The effectiveness of the organic titanates as corrosion inhibitors is demonstrated by the data in Table I which were obtained under the following conditions: Test strips of cadmium-silver alloy were submerged in a sample of highly refined motor oil which was normally corrosive to alloy bearings of the cadmium-silver type and a sample of the same motor oil containing 0.25% butyl titanate, which were heated and maintained at a temperature of about 341 F. At regular intervals the test strips were removed from the oils, washed with a solvent, dried and weighed, and the time in which the bearings lost 5 mg/cm? noted. The test strips in the sample containing no butyl titanate lost 5 ling/cm. in less than one day while the test strip in the sample of oil containing 0.25% butyl titanate lost 5 mg/cm. in about two days.
Table I Corrosion, time (in days) for test strips to lose 5 mg/cm.
Oil
Control (highly refined S. A. E. 20
mot
As used herein highly refined lubricating 011 means viscous oils which have a minimum viscosity of S. A. E. 10 oils, or higher, and which have been subjected to such refining processes that the paraflinicity of the oil is markedly increased. It has been found that highly refined lubricating oils cause corrosion to alloy bearings ofthe hard metal type, such as cadmium-silver alloy bearings to the extent of about 5 mg/cm. and even greater when such bearings are submerged for 25 hours or less in an air agitated oil which has been preoxidized at about340 F. for 25 to 50 hours. 'The motor oil may be highly refined lubricating oils as such or mixtures of highly refined lubricating oils with less highly refined lubricating oils, or stated in another way, mixtures of corrosive oilsv and non-corrosive oils, examples of the latter being lubricating oil fractions from Winkler crude or crudes of the Winkler type.
In addition to their use as E. P. lubricants in motor oils these organic titanates may be employed in lubricants such as oils and soft greases adapted for use on bearing surfaces which are subjected to high pressures and high rubbing velocities, such as are encountered in devices employed for the transmission of power such as hypoid gears, worm gears, heavy duty bearings, planetary automatic shifts and the like. The lubricating oils are preferably those ranging in viscosity from about to 200 seconds Saybolt at 210 F. If desired, calcium, lead, aluminum or other soaps of high molecular weight organic acids may be added to -the composition to increase the viscosity or the consistency of the lubricant. The organic titanates may also be used in combination with other compounds which impart extreme pressure characteristics to lubricants such as for example, lead soaps, chlorine compounds, sulfurized oils, etc. These compounds are likewise suitable for lubricants used in cutting and drawing operations where the oil must withstand the high pressures encountered under those conditions of use.
