COMPOSITIONS OF NON-LITHIUM GREASE

Siddharth Grease & Lubes Pvt. Ltd., an Indian Company, of Plot No. 13,
Sector-3, IMT Manesar, Haryana 122050, India

The following specification describes the invention and the manner in
which it is to be performed.

FIELD OF THE INVENTION
The present invention generally relates to lubricating compositions
and more particularly to non-lithium compositions of grease. The
lubricating grease compositions are a non-lithium grease used for
industrial and automotive applications.
BACKGROUND OF THE INVENTION
Lithium greases are the most widely accepted and used by the
industry world over. As per the NLGI grease production survey “lithium
greases” share is over 80 of the total grease production. Lithium greases
have many advantages like good mechanical shear stability, high dropping
point, good water resistance, etc. The lithium grease have excellent
response to component additives and additive packages.
However, due to diversified utilization and escalation in prices of
lithium hydroxide, lithium grease is not sustainable for long time. Lithium
grease is expensive due to its high raw material and production cost.
Further, the dropping point of lithium grease, i.e., 180-190°C (356-374°F)
is lower for many high-temperature applications. The lithium grease is
generally not recommended for use in sliding and reciprocating
applications due to less adhesion. The lithium grease has been found to
have lower water resistance than some greases like calcium and calcium
complex greases. Further, the lithium greases do not contain inherent
corrosion resistance properties and specifically need additional anti- rust /
corrosion additives.
Efforts are being made to develop alternate thickeners to replace
lithium base greases. Non-lithium greases are having dropping point near
to lithium greases with salient features such as low oil separation and
improved texture.

3

Therefore, there is a need for compositions of non-lithium greases,
which can overcome the drawbacks of the above-mentioned solution.
OBJECT OF THE INVENTION
An object of the present invention is to provide a first non-lithium
grease with calcium acetate complex grease.
Another object of the present invention is to provide a second non-
lithium grease with polyurea greases.
Yet another object of the present invention is to provide a third non-
lithium composition of grease with molybdenum disulphide (MoS 2 ) and
graphite.

In accordance with a first aspect of the present invention, a first,
second and third non-lithium composition of grease is provided. The first
non-lithium composition may comprise, but not limited to, a base oil,
thickener, performance additives, and calcium acetate complex grease.
In accordance with a second aspect of the present invention, a
second non-lithium composition of grease is provided. The composition
may comprise, but not limited to, non-lithium grease consisting of a base
oil, thickeners, performance additives and polyurea greases consisting of
Toluene diisocyanate and amines.

8

According to a third aspect of the present invention, a third non-
lithium composition of grease is provided. The thirds composition may
comprise, but not limited to, a base oil, thickener, molybdenum disulfide
(MoS 2 ) and graphite, and extreme pressure (EP) & anti-wear (AW)
additives. In accordance with an embodiment of the present invention, the
first non-lithium composition of grease may contain, but not limited, to 40-
55 % by weight of the base oil. The second non-lithium composition of
grease may contain non-lithium consisting of, but not limited, 49-61% by
weight of the base oil. Furthermore, the third non-lithium composition of
grease may contain 71-81% by weight of the base oil.
The base oil may be selected from a group comprising, but not
limited to, solvent neutral (SN) 150, SN 500, bright stock (BS) 150 oils and
naphthenic oils or a combination thereof. The SN 150 base oil is known as
a light grade base oil at the lower end of the specifications for Grade I light
base oils. It is mostly used in lubricant and lubricant additives production.
It is a Group I base oil which has undergone solvent refining processes.
The SN 150 can be mineral based oil. The Group I base oils are classified
as less than 90 percent saturates, greater than 0.03 percent sulphur and
with a viscosity-index range of 80 to 120. The temperature range for these
oils is from 32 to 150 degrees F. Group I base oils are solvent-refined,
which is a simpler refining process.
The base oil SN 500 is defined as a light grade base oil at the upper
end of the specifications for Grade I base oils. It is mostly used in lubricant
production. It is a Group I base oil which has undergone solvent refining
processes. To finish the refining it was hydrogen treated to clear out any
impurities.The base oil bright stock (BS) 150 is defined as a base oil at the
upper end of the specifications for Grade I base oils. BS base oils are high
viscosity oils produced at Group I base oil refineries by atmospheric and
vacuum distillation, extracting and dewaxing solvents from residual oils.

9

Furthermore, the naphthenic oils generally have intermediate
viscosity index and very low pour points which make them useful in the
manufacture of specialty lubricants. Dewaxing is normally not required due
to the low quantities of linear paraffins (n-paraffins). The naphthenic base
oils have high solvency, excellent low-temperature properties and High
compatibility to certain resins or polymers. The naphthenic base oils are
particularly suited as metalworking fluids. The main functions of the
naphthenic oil is cooling and lubrication, thereby providing a balance
between the cooling and lubrication.
Further, in accordance with an embodiment of the present invention,
the first composition of grease may contain, but not limited to, 9-10 % by
weight of a combination of fats and fatty acids. The second non-lithium
composition of grease may contain non-lithium grease consisting of, but
not limited, 9-10% by weight of a combination of fats and fatty acids.
Furthermore, the third non-lithium composition of grease may contain 9-
11% by weight of a combination of fats and fatty acids. The combination of
fats and fatty acids may be selected from a group comprising, but not
limited to, hydrogenated castor oil, Stearic acid, and 12 hydroxy stearic
acid or a combination thereof. The hydrogenated castor oil is available in
wax, powder, or flake form with high-melting-point. These different forms
are used as a viscosity modifier and for improvement in grease and oil
resistance. The Hydrogenated Castor Oil is an extremely versatile
oleochemical that has a number of industrial and manufacturing
applications. Because of its excellent resistance to moisture,
Hydrogenated Castor Oil works extremely well as a viscosity modifier, and
it also provides significant improvement in grease and oil resistance.
Further, the stearic acid provides excellent resistance to wear and
friction and it is environmental-friendly. The stearic acid, due to its anti-
wear properties, can be used in compounding lubricating oil additives,
such as corrosion inhibitors. Further, the 12 hydroxy stearic acid exists in

10

solid and liquid form. The 12 hydroxy stearic acid is an efficient viscosity
builder and gelling agent. Salts made from the 12 hydroxy stearic acid can
function as oil/water emulsifiers. Waxiness of the 12 hydroxy stearic acid
makes it ideal for creating long-lasting greases for the automotive industry
and industrial applications. It is used in the continuous grease process.
Greases made with 12 hydroxy stearic acid can be formulated to higher
drop points. The greases experience less bleeding and improved oxidative
stability.
In accordance with an embodiment of the present invention, the first
grease may comprise 10-12% of the thickener. The second non-lithium
composition of grease consisting of, but not limited to, 9-12% of thickener.
Furthermore, the third non-lithium composition of grease may contain, but
not limited to, 9-12.5% of thickener. The thickener maybe selected from a
group comprising 12-hydroxy stearate soap and stearate soap or a
combination thereof. The 12-hydroxy stearate soap, may be 12-hydroxy
stearate metal soap, is used to stabilize and thicken lubricating greases.
The 12-hydroxy stearate soap has high melting temperature and the high
frequency of hydroxyl hydrogen bonding in its aggregates.
Further, the stearate soap can be added to make lubricants suitable
for temperatures up to 750°C. The stearate soap, may be metal stearate
soap, can be used to prepare low-flame point hydraulic oils and lubricating
oils having a useful viscosity index. The addition of stearate soap also
reduces the fluid resistance and initial shear stress of the drilling mud. The
grease with the stearate soap works more effectively under high-pressure
conditions. At the same time, this dry film lubricant is waterproof and easy
to use. Mixing the stearate soap, aluminium stearate, and magnesium
stearate can produce oils for roller bearings and ball bearings.
In accordance with an embodiment of the present invention, the first
grease composition may comprise, but not limited to, 1-3 % of the

11

performance additives. The second non-lithium composition of grease may
contain non-lithium grease consisting of, but not limited to, 1-3% of
performance additives. The performance additives may be selected from a
group comprising antioxidants, extreme pressure additive, and anti-wear
additives or a combination thereof. In accordance with an embodiment of
the present invention, the third composition of grease may comprise, but
not limited to, 0.5-3.0% of extreme pressure (EP) & anti-wear (AW)
additives. The antioxidants are used for the protection of lubricants against
oxidation. Antioxidants are additives designed to prolong the life of a
lubricant by increasing the oxidative resistance of the base oil.
Antioxidants allow lubricants to operate at higher temperatures than would
otherwise be possible without them. The antioxidants such as, but not
limited to, Zinc dialkyldithiophosphates (ZnDDPs), hindered phenols,
alkylated diphenylamines, organomolybdenum compounds and
dithiocarbamates.
Further, the extreme pressure additive may be used under heavier
loads, at high temperatures and low speeds to prevent catastrophic failure
or seizing of application. The extreme pressure additives may be used in
gear oils, other power-transmitting fluids, load-bearing greases and
metalworking fluids. They are supplemented with anti-wear additives to
make these fluids effective across a wide range of pressure and
temperature conditions. The extreme pressure additives alleviate the
dramatic effect of ‘dry’ friction by preventing destructive metal-to-metal
contact in lubrication at high temperature and pressure conditions such as
those found in certain gear elements in automotive vehicles and various
industrial machines where high pressure can cause a film of lubricant to
rupture. The extreme Pressure additives may be selected from, but not
limited to, molybdenum disulfide, graphite, sulfurized olefins and
dialkyldithiocarbamate complexes.

12

Furthermore, the anti-wear additives are used in the grease to
prevent metal-to-metal contact between parts of gears. The anti-wear
additives react chemically with the metal surfaces when metal-to-metal
contact occurs in conditions of mixed and boundary lubrication. They are
activated by the heat of contact to form a film that minimizes wear. The
anti-wear additives may be selected from a group comprising Zinc
dialkyldithiophosphates (ZnDDPs), Tricresyl phosphate (TCP),
Halocarbons (chlorinated paraffins), Glycerol mono oleate, and stearic
acid.
In accordance with an embodiment of the present invention, the first
composition of non-lithium grease may comprise 25-35 % calcium acetate
complex grease. The calcium acetate complex grease have better high
temperature properties than calcium greases due to being a complex
soap. The calcium acetate complex greases have good water resistance
and the calcium acetate gives good extreme pressure properties. The
calcium acetate complex grease can be used in high temperature
industrial bearings, automotive bearings, and constant velocity joints.
Table 1 and table 2 provides calcium grease (VG 150) test data and
calcium acetate complex grease (VG 150) test data.
Further, the second non-lithium composition of the grease comprises
the polyurea greases. The polyurea grease tends to have high
temperature performance, inherent anti-oxidative properties, very good
water resistance, good mechanical stability and can exhibit either high-
shear stability or thixotropic behaviors. The polyurea greases may be
consisting of, but not limited to, 7-10% by weight of the Toluene
diisocyanate. The Toluene diisocyanate is an oxidation resistance
thickener making grease suitable for high temperatures. The thixotropic
behavior of the Toluene diisocyanate thickener may give the grease
excellent mobility, helps to seal the bearing from contaminants and
prevents leakage. Table 3 and provides polyurea grease test data. Table 4

13

provides test data of Ca-grease (non-lithium) blended with Ca- acetate
complex. Table 5 and table 6 provides test data for Ca-grease blended
with polyurea. Further, table 7 provides test data for Ca-grease blended
with 30% (approx.) polyurea.
Further, the polyurea greases further consisting of 13-16% by weight
of the amines. The amines perform vital functions in grease. The amines
neutralize acid-functional ingredients, as well as also causes development
and maintenance of alkaline pH. Additionally, the neutralization products
function as corrosion inhibitors, emulsifiers and lubricants. Further the
amines improve fluid microbial resistance through positive interactions with
biocides. The amines cause reduced levels of microbes, fewer additions of
biocide and longer fluid life. The amines may be selected from a group
comprising, but not limited to aniline, o-toluidine, p-toluidine, hexadecyl
amine, and octadecyl amine or a combination thereof. Table 8 provides
data for storage stability of polyurea + calcium acetate complex greases.
Table 9 provides test data for mixed base polyurea- commercial. Table 10
provides test data for polyurea and calcium acetate complex in ratio 50:50.
In accordance with an embodiment of the present invention, the third
non-lithium grease may comprise 1-3% of the molybdenum disulfide
(MoS 2 ) and graphite. The MoS 2 enhances the grease to sustain extreme
pressure and provide anti-seize properties to the grease. The MoS 2 has a
good mechanical stability, resulting in a long lifetime of the grease.
Further, graphite assists the grease to increase the durability of the
machine. The graphite is one of the elements of chemically formed
carbon. The carbon atoms are strongly formed with each other. It can
stand against the friction of the two surfaces hence is being used in the
grease. The graphite is mixed in the grease, to increase the workability of
the grease. The graphite minimizes the frequency of lubrication by
providing effectiveness for a longer duration. It allows grease to be
effective on the metallic surface for a longer period of time.
