Description

The preparation method of polyureas-compound calcium grease
Technical field
The present invention relates to the preparation of greases method.
Background technology
Polyureas-common preparation method of compound calcium mixed base grease prepares earlier two kinds of basic fat respectively, mixes by a certain percentage again.Provide a kind of method for preparing polyureas-compound calcium as CN1364859A, polyureas and compound calcium prepare respectively earlier, mix by a certain percentage again, complex procedures because lubricating grease viscosity is very big at normal temperatures, can't be used mechanical pump, change the still process by manually finishing, take time and effort.US 5,084, and 193 provide a kind of method for preparing polyureas-compound calcium grease, and prompting should be done polyurea grease earlier and do composite calcium-base fat again, also can prepare in reverse order, and be good but recommend last order.Yet when preparing polyureas-composite calcium-base fat according to last order, also have a problem, promptly after making polyurea grease, the temperature in the still has generally risen to 70-80 ℃, adds organic acid this moment more serious low molecular acid volatilization phenomenon can take place.
From above introduction as can be seen, during preparation polyureas-composite calcium-base fat, prior art is not advocated preparation composite calcium-base fat earlier, the method of refabrication polyurea grease, this may be owing to pot phenomenon that can rise in the process of preparation composite calcium-base fat, and promptly a large amount of foams rapid overflow in pot is in case this phenomenon occurs, defoamer must be added immediately, otherwise serious consequence can be caused.And those skilled in the art it is generally acknowledged and have been difficult in the same still preparation polyurea grease after pot phenomenon that rises.
Summary of the invention
The present invention overcomes the prejudice and the misleading of prior art, and a kind of direct method for preparing polyureas-complex calcium lubricating grease is provided.This method is preparation composite calcium-base fat earlier, does polyurea grease again, finishes in same still, not only can simplify the operation, and the polyureas-complex calcium lubricating grease that is obtained has more excellent characteristic.
Preparation of greases method of the present invention comprises: with base oil and calcium hydroxide (or calcium oxide), water and C 1-C 20Organic acid mixes, and is warming up to 30～100 ℃, adds vulcabond and organic amine, and the draining saponification is warmed up to 210～230 ℃, cooling, homogenizing.
Specifically, lubricating grease of the present invention can adopt following method preparation: at first the base oil with base oil gross weight 40～60% mixes in system fat still at normal temperatures with calcium hydroxide (or calcium oxide) and water, adds C then respectively 1-C 20Organic acid can be one or more acid, whenever add a kind of acid after, preferably reaction earlier adds another kind of acid after about 5～15 minutes again, after whole acid all adds, heats up.When temperature rises to 30～100 ℃, in the time of preferred 50～80 ℃,, pour in this still vulcabond heating for dissolving in 10～20% base oil, add C subsequently 8-C 24Organic amine, the draining saponification is until being warmed up to 210～230 ℃, add the surplus base oil, begin the circulation cooling, and in about 120 ℃, carry out homogenizing, homogenization pressures is generally 0.6～0.8MPa, and the homogenizing time obtains polyureas-composite calcium-base fat for being generally 10～50 minutes.Can in basic fat, add conventional additives as required, as oxidation inhibitor, rust-preventive agent etc.
Described base oil is mineral oil, ester class oil, synthetic hydrocarbon, plant wet goods.100 ℃ of viscosity are 20～40mm 2/ s is preferably 25～35mm 2/ s.
Said C 1-C 20Organic acid is selected from formic acid, acetate, propionic acid, phenylformic acid, diprotic acid, n-caprylic acid, boric acid, ten dihydroxystearic acids, stearic acid etc.Preferably select two kinds or two or more acid for use, generally select a kind of low molecular acid and a kind of polymer acid at least for use, select a kind of middle molecule acid (perhaps boric acid) in case of necessity again for use, it is generally acknowledged that the following acid of C6 is low molecular acid, the acid of C6-C10 is middle molecule acid, the above acid of C10 is polymer acid, and wherein the mol ratio of low molecular acid and polymer acid is 0.9～4: be advisable in 1 scope.
Said isocyanic ester is 4,4 '-diphenylmethanediisocyanate or 2, vulcabond such as 4-toluenediisocyanate.
Said carbon number is 8～24 preferred eight amine of organic amine, amino dodecane, cetylamine and stearylamine and cycloalkanes amine.
In the lubricating grease of the inventive method preparation (is benchmark with lubricating grease weight): base oil content is 50～90%, preferred 75～85%, viscosifying agent content is 10～50%, preferred 15～40%, described viscosifying agent comprises polyurea thickening agent and composite calcium-base viscosifying agent, wherein polyurea thickening agent is to be formed by organic amine and isocyanate reaction, and the composite calcium-base viscosifying agent is to be formed by organic acid and calcium hydroxide (or calcium oxide) reaction.The weight ratio of polyurea thickening agent and composite calcium-base viscosifying agent is 1: 0.3～3, preferred 1: 0.7～2.All determine consumption according to stoichiometric ratio between calcium hydroxide (or calcium oxide) and the organic acid and between vulcabond and the organic amine, the water yield is 1～5 times (weight) of calcium hydroxide (or calcium oxide).
Preparation method provided by the invention prepares composite calcium-base fat earlier, and the refabrication polyurea grease is not only easy and simple to handle, and has overcome the defective that prior art exists: owing to be to add organic acid under normal temperature even low temperature, can effectively avoid the volatilization of low molecular acid; Simultaneously add vulcabond and organic amine after adding organic acid but when also not rising pot, a pot phenomenon more just can not occur rising.In addition, polyureas-complex calcium lubricating grease that this method makes has excellent high-temperature performance, colloid stability, mechanical stability and extreme pressure anti-wear, can be used for high temperature, at a high speed, bearing lubrication such as heavy loading running, oil drilling.
