Universal Synthetic Penetrating Lubricant, Method and Product-by-Process
Field of the Invention
This invention relates to a synthetic penetrating lubricant capable of
dissolving rust and corrosion
caused by oxidation and harsh chemicals while offering extreme pressure
lubrication capacities with a high
dielectric protection.
Background of the Invention
Over the years many penetrating compounds have been developed to penetrate
rust and corrosion, but
they exhibit few if any lubrication qualities. Further many topical lubricants
have been developed for
lubrication, but again exhibit little if any penetrating capacity. Of the many
products developed, few have
demonstrated extreme pressure capability. Further, there are several
industrial products offering the benefit of
dielectric strength. Those tested found to be far short of their claims.
Further there are a number of products
developed to clean electrical contacts to reduce resistance and associated
heat. Again these products sorely lack
the ability to lubricate or penetrate rust and oxidation.
Summary of the Invention
Disclosed herein is a penetrating lubricant with the capacity to penetrate
rust and corrosion caused by
oxidation or harsh chemicals, into the crystalline surface of the metal,
leaving a non-migrating lasting lubricant
with extreme pressure capabilities. Further the product offers the ability to
clean electrical contacts for
improved conductivity while offering insulation and isolation by way of an
extremely high dielectric strength.
Further the product when applied to ferrous and non-ferrous material, is
resistant the environment including salt
waters. This penetrating lubricant comprises alpha-olefins; low-odor aromatic
solvents; and at least one a base
oil selected from the base oil group consisting of hydrolsomerized high base
oils and HT Severe Hydro-cracked
Base Oils; as well as other ingredients. Also disclosed is a method for
producing this penetrating lubricant.
Specifically, disclosed is universal synthetic penetrating lubricant for
penetrating and dissolving rust
and corrosion and cleaning metal and removing oxidation, while providing
lubrication including extreme
pressure lubrication, high dielectric protection, and corrosion resistance,
comprising: alpha-olefins; low-odor
aromatic solvents; at least one base oil selected from the base oil group
consisting of hydrolsomerized high-base
oils and HT severe hydro-cracked base oils; and high flash mineral spirits.
Detailed Description
The invention relates to the use of a multi-functional penetrating lubricant
with applications as a
general penetrating liquid for dissolving and loosening of corrosion and rust
caused by oxidation or harsh
chemicals. The invention further has the ability to penetrate into the
crystalline surface of metal, leaving a
lubricating film that is resistant to future corrosion. Further the invention
leaves a barrier film that has extreme
pressure capacity. Further the invention acts as a solvent to remove oxidation
between electrical contacts to
allow maximum flow of electricity while reducing resistance and heat
associated with resistance. Although the
invention cleans contacts for reduced resistance, it also isolates and
insulates electrical contacts to protect them
from moisture and other such elements which can cause electrical shorts and
failure. The invention

demonstrates high dielectric strength while exhibiting the characteristics of
a penetrant, lubricant, extreme
pressure lubricant, and contact cleaner.
Primary Ingredients
The preferred embodiment of the invention is a combination of:
= Alpha-Olefins: This is a primary ingredient which is a derivative of
linear alpha-olefins incorporating
1-decene to distinguish it from other mono-olefins by way of polymerization
and hydrogenation.
These are also known as Alkenes, Polymerized Chlorowax Liquids, and
Chlorinated Paraffins whose
carbon chain length are C12, C14, C12-24, C16-18, C24-30 and C20-30 with said
choleric weight
percentage from 21.4% to 70%, an HCI of 4 to 10 ppm and molecular weight of
273.5 to 650 and Wt.
Cl (2) from 20 to 70% with specific gravity at 25 degrees centigrade of 1.050
to 1.50 and a JQD
weight percentage of HCL being 0.20 to 0.60 maximum. The primary use is for
this ingredient is for
lubricant formulations, lubricant additive compounds, extreme-pressure
additive formulations and for
metal working compounds. Further, alpha-olefins or associated products reduce
the growth of algae in
fuel as aging or excessive moisture accumulates and stabilize the fuel over
time while providing
extreme lubrication to the fuel system and the firing chamber of the engine.
= Low-odor Aromatic Solvents: This is a primary ingredient which is a
highly-refined, low toxic, low-
odor solvent ideal for paints, varnishes, food grade coatings, adhesives,
diluents, thinners,
agrochemicals, household pesticides, a thinner for spray oils/lubricants and
specialty chemicals.
Aromatic percentage is 5 to 40% (EC-A-G04), a flash point of 20 to 80 degrees
centigrade (ASTM D-
93) and a density at 30 degrees centigrade (plus/minus) 0.600 to 0.900 (ASTM D-
4052).
= Hydrolsomerized High-Base Oils or HT Severe Hydro-cracked Base Oils: This
primary ingredient is
a severe hydro-cracked or hydrolsomerized base oil with low or no aromatics
and impurities achieved
by chemically reacting the feed stock with hydrogen (3000 PSI.) to reduce or
remove polar
compounds containing sulphur, nitrogen and oxygen and to convert aromatic
hydrocarbons to
saturated cyclic hydrocarbons breaking up the heavy polycyclo-paraffin
molecules to light saturated
hydrocarbons. This may include fractionated oils that have been hydro-finished
or hydro-polished.
The base oils can be used in a host of lubricating oils, motor oils, cutting
oils, food processing,
pharmaceutical, industry, agriculture lubricants and extreme pressure
additives. These add to the
lubrication of ultra low sulfur diesel fuel.
= High Flash Mineral Spirits: A colorless homogeneous solution with an
evaporation rate of .11 (n-
butyl acetate) and referred to as petroleum distillates that has been
synthesized from selected
hydrocarbons. This is often referred to as Stoddard Solvent #3 and / or
Mineral Spirits, and is
commonly used as an cleaning solvent, solvent in aerosols, paints, lacquers,
varnishes and paint
thinners for household and commercial use and has been subjected to
hydrodesulfurization solvent
extraction with a mixture of saturated aliphatic and alicyclic C7-C12 with a
maximum of 40%. The
flash point ranges from 40 to 55 degrees centigrade, aniline point of 60 to 85
degrees centigrade and a
vapor density of 0.758 (kg/L) at 15 degrees centigrade. This component assists
in dissolving
oxidation and is necessary when pressurizing the finished product in aerosol
containers.

Other Ingredients
= Synthetic Calcium Sulfonates: An over based calcium sulfonate with a TBN
of 100 to 600, which
may be prepared from C20-C24 linear monoalkyl phenylsufonic acid, and whose
primary purpose is
for extreme pressure additive formulations offering corrosion protection,
dispersants and detergency in
oil soluble additives for ferrous and no-ferrous metals with a minimum calcium
weight of 10.00 to
20.00%, a total base number, mg KOH/g (ASTM D-2896) of 100 to 600 and an
average molecular
weight (ASTM D-3712) of 800 to 1200.
= Methyl-Isobutyl Ketones (MIBK): Formula (6H12) CAS 108-10-1, Flammable
Liquid. MIBK is
general used a as solvent for vinyl, epoxy, acrylic and natural resins,
nitrocellulose, paints, varnishes,
lacquers, protective coatings, rare metal extractions and dyes. Further it is
commonly used in
manufacturing antibiotics, dry-cleaning preparations and the synthesis of
methyl isobutyl carbinol. It
occurs naturally in oranges, grapes and vinegar. It is colorless, has low
boiling point, and is miscible
in proportions with water, alcohols, most hydrocarbons and other organic
liquids. MIBK has a flash
point of 14 degrees centigrade. MIBK is manufactured from acetones via a three-
step process
involving dimerised alcohol condensation to diacetone alcohol. Further
diacetone readily hydrates to
give mesityl oxides. Mesityl oxides can then be hydrogenated to MIBK. MIBK is
used as a
denaturing agent for denatured alcohols and as such lends itself a quick
drying agent.
= Solvent activated dyes: An alcohol (NAHA) solution of polymer color
forming compounds. These are
commonly used to identify grades or designated uses of fuels and lubricants.
They are produced in
both powder and liquid form and when introduced to the product are stable and
leave an identifiable
color to the product.
= Solvent-Activated Fragrance: Alcohol-concentrated fragrance essence with
an HA or NAHA of
.005% to 1%. The active ingredient resists bacterial growth and contains a
molecular encapulant
(fixative) to maintain the selective fragrance uses to mask the chemical odor
of certain compounds.
= Polytetrafluoroethylene (fluoroadditive): CAS No 9002-84-0. Fluoroadditives
are organic polymers
in colloidal form that when blended into a solvent base compound and applied
are highly-resistant to
water or weathering conditions.

preferably 0.022 to 0.0925%
and more preferably 0.042 to 0.085% by weight. Most preferable is 0.0835 % by
weight.
Preferred Sequence of Blending Components
The initial blend (primary blend) will require the alpha olefins, the low-odor
aromatic solvent and the
base oils being blended until the liquid is a consistent amalgamation without
any appearance of separation.
Blending is based on speed of the agitator and temperature will dictate the
amount of time for the blend to
complete. The blending time range may vary from 4 to 6 hours. The ideal
temperature for each component is
between 22 to 30 degrees centigrade for ideal blending.
While this is blending, a secondary blend for the methyl isobutyl ketones,
solvent activated dyes and
solvent activated fragrance is prepared in a much smaller high-speed enclosed
blender, and then added to the
main blend.
The synthetic calcium sulfonates will be blended with the mineral spirits in
an approximate .25/75 ratio
in the initial stage of the blend to produce a tertiary blend. (The mineral
spirits used will be from the preferred
percentage set forth earlier.) This tertiary blend, or the mineral spirits
alone absent the synthetic calcium
sulfonates, together with the balance of the ingredients, can be then added to
the main blend and the agitator is
run until the components appear to have thoroughly blended into a consistent
liquid.
Preferred Blend Equipment
The process sequence involves a series of blending and holding tanks where the
product can be
weighed and then pumped through control valves to maintain consistent flow and
pressure. The blending should
be performed in an enclosed tank to reduce product evaporation (loss) and
prevent exposure to open spark.
Blending equipment can be by a combination of high or low speed blending
apparatus. Size or volume of tank
is not critical to the blend.
Universal Use of Invention
The product has been industrially tested, on an experimental basis, in extreme
and harsh conditions.
The invention has been so-tested in various forms of machining, and in
electrical applications where elements
such as water are a constant source of shorting and electrical safety and
failure are a concern. The invention has
been tested as an extreme pressure topical lubricant and has exceeded the
performance of most lubricants
4
CA 02710530 2014-12-11
available. Finally the product has been severely tested, experimentally, in
applications with extreme
rust and corrosion and has demonstrated the ability to penetrate and loosen
the same while leaving a
protective barrier on the metal. The product has shown its ability to work
well with ferrous and non-
ferrous material with profound results including the protection of brake
rotors.
Testing Procedures
As the product is unique in its field and as such has been tested on the
Timken Bench Tester
and has demonstrated the capacity to exceed the lubrication capacity of an
engine lubricant many time
over. When tested the average engine lubricant failed at 5 to 7 foot-pounds.
The average penetrant
failed at less than 2 foot-pounds while the invention exceeded 30 foot-pounds
of destructive weight.
Further when tested for dielectric strength, the invention exhibited the
capacity of over 8000 volts
protection. When the invention was tested in machine, tapping and drilling,
the invention allowed the
tool to leave a highly refined finish on the points of contact and pressure.
Test Results
As there is no particular ASTM-D test protocol to measure the ability of a
multi-purpose
penetrating lubricant, the inventor has had to rely on actual results from
hands on use of the products
in various fields of testing.
This experimental testing has demonstrated the ability of the invention to
show dramatic
improvement in all the fields of testing, to such a degree that there may be
potential to exhibit positive
results in application areas yet to be considered.
While only certain preferred features of the invention have been illustrated
and described,
many modifications, changes and substitutions will occur to those skilled in
the art.
