Description
(54) LUBRICANT COMPOSITIONS
(71) We, ROCOL LIMITED, of Rocol House, Swillington, Leeds, LS26 8BS, a British Company, do hereby declare the invention, for which we pray that a patent may be granted to us, and the method by which it is to be performed, to be particularly described in and by the following statement:- The invention relates to lubricating compositions.
The use of solid lubricants e.g. graphite and molybdenum disulphide as additives to greases and other lubricants, is well known. Addition of solid fillers such as calcium carbonate to lubricating greases in order to reduce the cost of the product composition has also been practised to some extent for many years.
It has been widely accepted that molybdenum disulphide is particularly effective under high loads and that it has the property of reducing wear under these conditions. Recently however rapid increases in the price of molybdenum disulphide have prompted research into cheaper, but equally effective alternatives.
Surprisingly we have discovered that compositions containing in combination a halogenated organic lubricant and a Group IIA metal carbonate, (the term
Group IIA metal is defined as calcium and the other metals of the group but not magnesium), optionally with molybdenum disulphide also, give excellent results, comparable to or in some circumstances better than those given by conventional molybdenum disulphide compositions. The best results are obtained when a finely divided inorganic sulphate salt, particularly an alkali in alkaline earth metal sulphate is present also.
The compositions may be used alone or in lubricating bases, particularly synthetic and mineral oil greases, in which the amount of additives relative to the base may vary widely according to the type of product and its intended use. There are for example products on the market with 3% molybdenum disulphide and others with 50% and the compositions of the invention may substitute for all or part of these amounts or be present in any other effective amount compatible with the required physical properties of the product. Generally, the final products may be pastes, greases, oils or solid lubricating films; where the compositions are sold alone they may be for use as lubricants in themselves or use by lubricant blending manufacturers.
The amount by weight of inorganic sulphate, where used, is preferably approximately equal to that of the halogenated lubricant, with 5 to 15 times as much of the group IIA carbonate by weight, as halogenated lubricant.
Preferred halogenated lubricants are halogenated hydrocarbons, particularly chlorinated paraffins. Fluorinated materials where used must be solids or waxes at normal ambient temperatures.
Our most preferred materials are calcium carbonate (whiting) and calcium
sulphate hemihydrate, preferably in combination with the chlorinated paraffins, but other materials are successful, for example other carbonates; other sulphates
such as magnesium sulphate. 7H2O, calcium sulphate mono- and di-hydrates, anhydrous sodium sulphate, potassium sulphate, potassium aluminium sulphate, zinc sulphate, sodium hydrogen sulphate, and sodium thiosulphate . 5H2O, and, among halogenated lubricants, materials exemplified by 'Cereclor' (Trade Mark)
chlorinated long chain paraffin hydrocarbons grades 70 (powder), 70 L, 63 L and 50
LV (I.C.I.); similar bromoparaffins; fluorinated graphites of formula (CFx)n (Air
Products); 'Fluon' (Trade Mark) L 169 polytetrafluoroethylene (I.C.I.); and
oligomer based fluorochemical waxes such as RDPE and RDPE-S Wax (I.C.I.).
The inorganic materials are, as will be understood, in finely divided form, for example the carbonate is suitably 99% less than 25 microns, 93% less than 10 microns.
The successful results of the invention are specific to the combination of components, as is shown by the following results of tests of various blends in white petroleum jelly as a lubricating base. The tests were done in the well known 'Seta- Shell' (Trade Mark) four ball test machine, used for assessing lubricant performance under extreme pressure. The smaller the scar diameter found, the better the lubricant. The compositions are by weight, the amounts of additives being relative to the composition as a whole.
The first five blends are comparative, showing first the petroleum jelly alone; then the effects of calcium sulphate hemihydrate, 'Cereclor' (Trade Mark) 63L (a chlorinated paraffin containing 63% chlorine), and 'Snowcal' (Trade Mark) 8/SW whiting (calcium carbonate) individually; and then the effect of the calcium sulphate and calcium carbonate together. Blends 6, 7, 9 and 10 show compositions containing halogenated lubricant and calcium carbonate and thus according to the invention, Blend 6 without calcium sulphate and Blends 7, 9 and 10 with Blend 10 further contains molybdenum disulphide, and Blend 9 (an assembly paste) anatase
TiO2, primarily to give a good white appearance but also giving a very high ultimate failure (weld) load.
Except at the lowest pressures Blend 7, with calcium sulphate, is better than
Blend 6, and both' are better than even the best of the comparative blends, particularly at the highest pressures, where a scar diameter of over 2 mm indicates approaching failure.
Finally in Blends 8 and 11 there are shown for comparison the effects of molybdenum disulphide (Blend 8) and 'Lonza' (Trade Mark) KS 2.5, a high quality artificial graphite (Blend 11). It will be noted that the compositions of the invention are superior to both these compositions throughout.

In further tests magnesium sulphate . 7H2O and anhydrous sodium sulphate were substituted for the calcium sulphate sulphate . +H2O of Blend 7 above, and 'Monflor' 53 for the 'Cereclor', with the results shown in Table 2.

In the following, further results showing the merits of the compositions of the invention are discussed, the 'blends' referred to being those of Table 1.
1. Comparison of Blend 7 with a Known Anti-scuffing Paste Test Method
The preferred composition in petroleum jelly (Blend 7) was compared with
Blend 8, which is a known anti-scuffing paste as used in engineering on an 'Amsler' wear test machine. In this machine two discs 2.5 inches (6.35 cm) diameter and 0.25 inches (6.35 mm) wide are used. One disc, of phosphor bronze, is fixed whilst the other, of hardened steel, can be rotated and loaded edge-on against the stationary disc. Rotation of the steel disc under load produces a wear scar on the bronze disc which can be accurately measured.
The technique used is to smear the two discs with the lubricant blend. The steel disc is rotated at a fixed speed and then loaded against the bronze disc, the test being continued for a given time calculated from the peripheral speed of the steel disc, and chosen to give a total of 250 feet (76.2 m) of sliding at the contact.
At the conclusion of each test the bronze disc is moved to give a fresh contact position and the test repeated at a higher load. A range of loads from 25 kg upwards in 25 kg steps up to 150 kg is used and the sliding speeds are from 25 feet/minute (12 cm/sec) in 25 feet/minute (12 cm/sec) steps up to 125 feet/minute (60 cm/sec). Each test is repeated to give a total of 3 tests for each condition.
Results
The wear scar measurement results in inches (cmx0.394) are plotted in Figure
1, and also in Figures 4 and 5 as three dimensional plots. The measurements, converted to volume of material worn away in cubic inches (cm3x0.06) and for clarity multiplied by 107, are plotted in Figure 2. Finally the wear scar width and applied loads have been used to calculate the final contact pressure, plotted in
Figure 3.
Discussions of Results
In broad terms the blends show the same general characteristics in that the amount of wear increases as the load increases, although not in direct proportionality, and also in that for any given applied load wear decreases as the speed is increased. (Care should be taken that the wear versus speed characteristics are not wrongly interpreted: the wear is for a given number of revolutions of the disc and not a constant time. Thus the 25 ft/min (12 cm/sec) tests ran for 10 minutes to produce the wear scar shown whereas the 125 ft/min (60 cm/sec) tests ran for 2 minutes only).
Examination of the wear curve shape however shows important differences between the blends. The curve slopes are quite different. In terms of magnitude of wear Blend 8 is clearly better at lower loads but the difference decreases as load increases and the curves cross/over, so that the Blend 7 exhibits a lower wear at higher loads. More significantly than actual wear scar width for a given load is that increase in wear with increase in load shows opposite characteristics for the two blends. With Blend 8 the increase becomes progressively greater as load increases but with Blend 7 the increase becomes progressively less.
Examination of the final contact pressure curves shows that Blend 8 gives a peak pressure at about 75 kg applied load-for all speeds- and thereafter decreases, whilst the Blend 7 contact pressure continues to rise. The full significance of this feature is not properly understood; it may well be that this represents a scuffing criterion or a change from 'mild' to 'severe' type of wear.
However it does illustrate the superiority of Blend 7 at higher contact loads.
Conclusions
The above tests show that the preferred composition in petroleum jelly (Blend 7) is effective as an anti-scuffing compound. In particular the preferred composition is more effective than the known Blend 8 at higher loads. This represents a significant advance in current boundary lubricant technology, since molybdenum disulphide is at present regarded as the most important solid lubricant in commerce for boundary lubrication.
2. Comparison of Anti-seizure Properties
Commercial anti-scuffing pastes such as Blend 8 are widely used as anti-seize lubricants on fasteners subjected to high temperatures. Comparison with the performance of Blend 7 under such conditions is given below.
Test Method
Mild steel nuts and bolts are:
i) degreased
ii) treated with the blend.
iii) tightened to a torque of 50 lb. ft (6.9 kg. m)
iv) subjected to the test conditions.
v) breakloose and prevailing torque are determined.
Results
(The torque figures quoted are in lb. ft (kg. mx0.138); BLT stands for break loose torque).

These results show the anti-seize properties of Blend 7 to be as good as a known anti-seize lubricant containing molybdenum disulphide.
3. Part Replacement of Molybdenum Disulphide in Commercial Open Gear
Grease
An important commercial use of molybdenum disulphide is to improve the performance of open gear lubricants. Part replacement of molybdenum disulphide by cheaper, but equally effective alternatives, is of significant commercial importance.
Test Method
A number of grease blends were made up at different molybdenum disulphide replacement levels. Table 5 below gives the composition of each blend, by weight.
