1. technical field
The present invention relates to high alkalinity (overbased, the parlkaline) sulfoacid calciums prepared by postponing the non-aqueous transforming agent of addition
Lubricating grease (grease, lubricating oil, grease) and the method for manufacturing this lubricating grease, to provide thickener yield
The improvement of (thickener yield) and the expection high temperature effectiveness such as proved by dropping point (dropping point), even if working as
When oil-soluble high alkaline calcium sulfonate for manufacturing lubricating grease is considered of poor quality.
2. background technology
High alkaline calcium sulfonate lubricating grease lubricating grease classification always set for many years.Manufacture one kind of this lubricating grease
Perception method is to be related to " promoting " and the two-step method of " conversion " step.In general, the first step (" promotion ") is the chemistry made as alkali source
Measure excessive calcium oxide (CaO) or calcium hydroxide (Ca (OH)2) and alkyl benzene sulphonate, carbon dioxide (CO2) and and other components
Reaction is to generate the oil-soluble high alkaline calcium sulfonate for being dispersed with amorphous calcium carbonate wherein.These high alkalinity oil-soluble sulfonic acid calcium
Normally transparent and bright, has Newtonian rheology.In some cases, they may be slightly muddy, but this variation and there is no harm in
Them are hindered to be used to prepare high alkaline calcium sulfonate lubricating grease.For purposes of this disclosure, term " high alkalinity oil-soluble sulfonic acid calcium " and
" oil-soluble high alkaline calcium sulfonate " and " high alkaline calcium sulfonate " refer to any high alkalinity sulphur for being suitable for preparing grease of calcium sulfonic acid
Sour calcium.Typically, second step (" conversion ") is to promoting the product of step to add one or more transforming agents such as propylene glycol, different
Propyl alcohol, water, formic acid or acetic acid are together with suitable base oil (e.g., mineral oil) (if necessary) to keep initial lubricating grease less
Firmly, amorphous calcium carbonate is converted to the crystalline calcium carbonate of superfine dispersion.When using acetic acid or other acid as transforming agent,
Generally also use water and another non-aqueous transforming agent (third transforming agent, such as alcohol);Alternatively, water is only added (without third to turn
Agent), but then convert and usually occur in pressurizing vessel.It is high-alkali to realize due to the use of excessive calcium hydroxide or calcium oxide
Change, thus a small amount of residual oxygen calcium or calcium hydroxide can also be used as oil-soluble high alkaline calcium sulfonate a part exist and
It will be dispersed in initial grease structure.The crystal type of calcium carbonate is preferably calcite.This superfine dispersion calcium carbonate (
Referred to as aqueous colloidal dispersion) it is interacted with sulfoacid calcium to form greasy consistency.This high alkalinity produced by two-step method
Grease of calcium sulfonic acid be referred to as " simple grease of calcium sulfonic acid (and simple calcium sulfonate grease, it is single
Grease of calcium sulfonic acid) ", and it is disclosed in such as U.S. Patent number 3,242,079,3,372,115;3,376,222、3,377,283、
With 3,492,231.
In the prior art it is also known that the two steps are combined into a step by carefully controlling reaction.In the one-step method
In, in carbon dioxide and functions simultaneously as accelerating agent and (generate reacting by carbon dioxide and excessive calcium oxide or calcium hydroxide
Both and the amorphous calcium carbonate of high alkalization) and transforming agent (crystalline calcium carbonate for converting amorphous calcium carbonate to superfine dispersion)
Reagent system in the presence of, moistened to prepare simple sulfoacid calcium by sulfonic acid appropriate and calcium hydroxide or reacting for calcium oxide
Consistent lubricant.Therefore, greasy consistency, wherein high alkalinity oil-soluble sulfonic acid calcium (first in two-step method are formed in one step
The product of step) it is actually never formed and is detached as individual product.The one-step method is disclosed in for example, U.S. Patent number 3,
661,622,3,671,012,3,746,643 and 3,816,310.
Other than simple grease of calcium sulfonic acid, sulfoacid calcium complex grease is also known in the prior art.Usually
By adding strong calcic alkali such as calcium hydroxide or oxidation into the simple grease of calcium sulfonic acid generated by two-step method or one-step method
Calcium, and with the Compound-acid of up to stoichiometric equivalents (complexing acid, complex acid) such as 12- hydroxy stearic acids, boron
Acid, acetic acid (it can also be transforming agent when being added before conversion) or phosphatase reaction prepare these complex greases.Sulfoacid calcium
Complex grease includes sticky reduction, pumping raising and the raising of high temperature effectiveness better than the advantages of report of simple lubricating grease.
Sulfoacid calcium complex grease is disclosed in for example, U.S. Patent number 4,560,489,5,126,062,5,308,514 and 5,338,
In 467.
Many knowns using two-step method teach while heating and usually add before heating
All transforming agents (water and non-aqueous transforming agent).However, some prior art references are disclosed in addition water and are added at least
Time interval (although always define unclear or do not define at all) between partial one or more non-aqueous transforming agents.Example
Such as, U.S. Patent number 4,560,489 disclose a kind of method (embodiment 1-3), wherein base oil and high alkalinity calcium carbonate are added
Then heat adds water to about 150 °F, then before addition acetic acid and methyl cellosolve (the high toxicity monomethyl ether of ethylene glycol)
Heat the mixture to about 190 °F.Obtained lubricating grease contains the high alkaline calcium sulfonate more than 38%, and ' 489 patents refer to
Go out, disclosed in the desired quantity of high alkaline calcium sulfonate of method be about 41-45%, because according to ' 489 patent uses be less than
38% generates soft grease.The gained lubricating grease of embodiment 1 in ' 489 patents has only about 570 °F of dropping point.' 489 patents
Do not illustrate to add the period of delay between water and the non-aqueous transforming agent of addition, but shows be heated to the just time of 190F from 150F
It is added immediately after section.Dropping point and thickener yield in ' 489 patents are worthless.
Made using aliphatic acid such as 12- hydroxy stearic acids in addition, U.S. Patent number 5,338,467 and 5,308,514 is disclosed
For the transforming agent being used together with methanol with acetic acid, wherein addition aliphatic acid does not postpone, but in addition water and addition acetic acid and
There are some time intervals between methanol.The embodiment 1 in embodiment B and ' 467 patents in ' 514 patents all describes a kind of side
Method is then adding wherein water and aliphatic acid transforming agent are added in other compositions (including high alkaline calcium sulfonate and base oil)
It is heated to about 140-145 °F before adding acetic acid then to add methanol.Then, about 150-160 °F is heated the mixture to until turning
Change and completes.The amount of the high alkaline calcium sulfonate in final grease product in two kinds of embodiments is 32.2, this is than desired
It is high.These patents do not illustrate to add the period of delay between water and aliphatic acid and addition acetic acid and methanol, but show not specified
Heating time after add immediately.Similar side is disclosed in the embodiment A and the embodiment C of ' 514 patents of ' 467 patents
Method, other than adding all aliphatic acid after being to convert, therefore the non-aqueous transforming agent being used only is by mixture and water
It is heated to the acetic acid and methanol that are added after 140-145F together.In these embodiments, the amount of high alkaline calcium sulfonate even compares
Previous embodiment is high by 40%.Other than ideal thickener yield results are not achieved, all these methods all use methanol
As transforming agent, this is with environmental gap.These ingredients may be caused to be discharged into air using volatility alcohol as transforming agent,
Latter portions as the lubricating grease manufacturing process that many areas in the world are forbidden.If do not discharged, must by washing or
Water knockout drum (water trap) recycles alcohol, this leads to detoxication cost.Better thickener is obtained therefore, it is necessary to a kind of
The method of yield preferably need not use volatility alcohol as transforming agent.
Better thickener yield is obtained in the embodiment 10 of ' 514 patents, but the use of superfluous lime is considered as obtaining
The requirement of these results.In this embodiment, water and superfluous lime are added together with other compositions, is heated the mixture to
180-190F, while it being slowly added acetic acid during heating.The lubricating grease of gained contains 23% high alkaline calcium sulfonate.Although should
Thickener yield is better than other, but there are still the rooms for improvement of bigger without using excessive lime, this is ' 514 patents
Introduction is requirement.
Other examples that there is thickener yield wherein for 23% or lower ' 514 and ' 467 patents are included in conversion
Period use autoclave, or as wherein add between water and non-aqueous transforming agent or both be not present " delay " at other
The much bigger part of the prior art.These embodiments include addition water and aliphatic acid transforming agent, mixing 10 minutes without heating,
Then acetic acid is added, in autoclave or in no pressure.These patents all do not recognize 10 minutes of addition acetic acid
Any benefit or advantage of interval or other heating delays in embodiment discussed above, make on the contrary, these patents concentrate on
Use aliphatic acid as transforming agent, and the benefit of addition aliphatic acid is observed as any before conversion, after conversion or both
The reason of yield improves.In addition, as discussed below, 10 minutes incorporation time intervals without any heating are not herein
" delay " of the middle term used, and it is considered identical as adding ingredient simultaneously, it is understood that it adds each ingredient and needs at least
Some times, and cannot occur moment.
Furthermore it is known that the prior art instruct calcium oxide or calcium hydroxide is used to be used as generating sulfoacid calcium lubrication always
The alkaline calcium source of fat or as being reacted with Compound-acid to form the required component of sulfoacid calcium complex grease.Known existing skill
Art teaches addition calcium hydroxide or calcium oxide needs enough amounts (to be present in high alkalinity oil-soluble sulfonic acid calcium when being added to
When a certain amount of calcium hydroxide or calcium oxide) to provide calcium hydroxide or the oxidation of the total amount for being enough fully to react with Compound-acid
Calcium.Such as in the Application U.S. Serial No of co-pending 13/664,574 and 13/664, disclosed in 768, it is known that existing skill
Art usually instructs calcium carbonate (as individual ingredient or as " impurity " in calcium hydroxide or calcium oxide, in addition to carbonating
Exist later except the amorphous calcium carbonate being dispersed in sulfoacid calcium) at least two reasons should be avoided.It is that calcium carbonate is logical first
Often it is considered as weak base, is not suitable for being reacted with Compound-acid to form best grease structure.Second the reason is that unreacted
Conversion process is interfered in the presence of solid calcium compound (including calcium carbonate, calcium hydroxide or calcium oxide), if before conversion or
Conversion is completed then to lead to lubricating grease inferior without removing unreacted solid before.However, applicant have found that addition calcium carbonate
As independent element (other than the amount of calcium carbonate contained in high alkaline calcium sulfonate), calcium hydroxy apetite (calcium
Hydroxyapatite, calcium hydroxyapatite) or combinations thereof (addition or do not add calcium hydroxide or calcium oxide) as with
The ingredient of Compound-acid reaction generates the brand-name grease as described in ' 574 and ' 768 applications.
There are several prior art references to disclose addition crystalline calcium carbonate as independent element (in addition to high alkalinity sulfonic acid
Except the amount of calcium carbonate contained in calcium), but these lubricating grease have difference thickener yield (such as teaching in prior art) or
Need the nano-sized particles of calcium carbonate.For example, U.S. Patent number 5,126,062 discloses the calcium carbonate conduct of addition 5-15%
The independent element of complex grease is formed, it also requires addition calcium hydroxide with Compound-acid to react.In ' 062 patent, addition
The calcium carbonate calcic alkali uniquely added that is not intended to react with Compound-acid.In fact, the calcium carbonate of addition does not add particularly
Add as the alkaline reactant reacted with Compound-acid.On the contrary, needing calcium hydroxide to be added as being reacted with all Compound-acids
Specific calcic alkali.In addition, No. 2 lubricating grease of the NGLI of gained contains the high alkaline calcium sulfonate of 36%-47.4%, this is a large amount of
The ingredient of this costliness.In another example, the open CN101993767 of China, which is disclosed, is added in high alkaline calcium sulfonate
The addition of the nano-sized particles (size is between 5-300nm) of calcium carbonate, although bibliography does not show to add calcium carbonate
Nano-sized particles as reactant, or only individually addition calcic alkali for being reacted with Compound-acid.Use nano-sized particles
Increase consistency of grease to keep its robustness, like by converting amorphous calcium carbonate institute contained in high alkaline calcium sulfonate
The crystalline calcium carbonate of formation fine dispersions (its can be about 20A to 5000A or according to ' 467 patents be about 2nm extremely
500nm), but compared with the calcium carbonate granule of the addition of large-size, cost can also be significantly increased.The Chinese patent application is very
The absolute necessity of the calcium carbonate with real nano particle size of addition is highlighted in big degree.Such as basis in co-pending
Shown in the exemplary lubricating grease of the present invention described in ' 574 applications, brand-name grease can be by adding micron order calcium carbonate
Formed, without using very expensive nano-scale particle, and when use the calcium carbonate of addition as one kind or with it is unique
When the calcic alkali of addition with Compound-acid to react.
There is also use tricalcium phosphate as the prior art references of the additive in lubricating grease.For example, the U.S. is special
The all introductions of profit number 4,787,992,4,830,767,4,902,435,4,904,399,4,929,371 use tricalcium phosphate as profit
Consistent lubricant additive.However, it is believed that being used with formula Ca without prior art references introduction5(PO4)3The hydroxy-apatite of OH
The mathematical equivalent thereof that stone calcium or fusing point are about 1100C manufactures lubricating grease, including sulfonic acid as the calcic alkali for being reacted with acid
Calcium-base grease.Several prior art references in the presence of the Showa Shell Sekiyu for belonging to Japan include that the U.S. is special
Sharp application publication number 2009/0305920, which depict contain tricalcium phosphate Ca3(PO4)2Lubricating grease and with reference to have formula [Ca3
(PO4)2]3·Ca(OH)2" hydroxyapatite " source as tricalcium phosphate." hydroxyapatite " this is referred to and being disclosed
It is different from the calcium hydroxy apetite disclosed and claimed in ' 768 applications for the mixture of tricalcium phosphate and calcium hydroxide,
And there is formula Ca herein5(PO4)3OH or mathematical equivalent thereof, fusing point are about 1100C.Although name has misleading, hydroxyl
Base apatite calcium, tricalcium phosphate and calcium hydroxide are individually the different compounds with different chemical formulas, structure and fusing point.When mixed
When being combined, two different crystalline compounds tricalcium phosphate (Ca3(PO4)2) and calcium hydroxide (Ca (OH)2) will not be mutual
Reaction otherwise generates different crystalline compounds calcium hydroxy apetite (Ca5(PO4)3OH).Tricalcium phosphate (has formula
Ca3(PO4)2) fusing point be 1670C.Calcium hydroxide does not have fusing point, but the son that dries out at 580C is to form calcium oxide.
The calcium oxide being thusly-formed has the fusing point of 2580C.Calcium hydroxy apetite (has formula Ca5(PO4)3OH or mathematical equivalent thereof) tool
There is the fusing point of about 1100C.Therefore, no matter how inaccurate name may have, calcium hydroxy apetite is not identical as tricalcium phosphate
Compound, and it is not the simple blend of tricalcium phosphate and calcium hydroxide.
In addition, it is expected that leading to the thickener yield improved with the composite lubricated oil/fat composition of sulfoacid calcium and its manufacturing method
And dropping point.Many known prior art compositions need the high alkaline calcium sulfonate of at least 36% amount (to be produced with final lubricating grease
The weight meter of product) to obtain the suitable lubricating grease in No. 2 classification of NGLI, the verified drop at least 575F
Point.High alkalinity oil-soluble sulfonic acid calcium is one of the ingredient of most expensive for manufacturing grease of calcium sulfonic acid, it is therefore desirable for reducing the ingredient
Amount, while still keeping firmness level's (thus improve thickener yield) needed for final lubricating grease.In order to realize the height used
The amount of alkaline sulfoacid calcium is greatly decreased, and many prior art references utilize pressure reactor.Expect to have high alkalinity sulfonic acid
Grease of calcium, wherein when consistency is in No. 2 grades of NLGI (or 60 stroke needle penetration (worked 60stroke of work of lubricating grease
Penetration, 60 stroke operation needle penetrations, used 60 stroke needle penetration, work 60 stroke of needle penetration, past by 60 times
Work needle penetration after multiple) between 265 and 295) in when, the percentage of high alkalinity oil-soluble sulfonic acid calcium is less than 36%, and
Dropping point is always 575F or higher, without pressure reactor.Since dropping point is limited about the high temperature effectiveness of lubricating grease
First is also to be easiest to determining guidance, therefore, it is considered that higher dropping point is desired.

Kind head cover or hatch are not airtight, to not will produce significant pressure during heating.This is used during conversion process
The open container that kind head cover or hatch are closed will be helpful to keep the necessary water as transforming agent, while allow generally for converting
The boiling point of temperature water under the boiling point of water or even higher than.As one of ordinary skill understood, this higher conversion
Temperature can cause the further thickener yield of both simple and composite calcium sulfonate grease lubricants to improve.It can also use and pressurize
It is manufactured in kettle, and the even greater improvement of thickener yield can be caused, but pressure process is possible more complicated and is difficult to
Control.In addition, manufacturing grease of calcium sulfonic acid in autoclave may result in productivity issue.The use of compressive reaction is to Mr. Yu
The lubricating grease (e.g., polyurea grease) of a little types is important, and most of grease plants only with limited quantity can
Use autoclave.Dress may be limited (in the case where compressive reaction is less important) using autoclave manufacture grease of calcium sulfonic acid
Set the ability that other lubricating grease are prepared in the case that those react critically important wherein.Open container avoids these problems.
