Description
Technical field
The invention belongs to chemical field, more particularly to a kind of thickening agent, more specifically, the present invention are used to prepare height to be a kind of
The thickening agent of thickening power is played during temperature lubricating grease.
Background technology
Hmp grease is generally used for more than 180 DEG C of use environment, and highest is even up to 800 DEG C or so, using being related to
Multiple industries.If the phenomenons such as volatilization, dry and carbon deposit occurs under the high temperature conditions in the Hmp grease that equipment is used, it can make to set
It is standby to be carried out under unlubricated state, considerable influence will be produced to equipment, the metal material of equipment can not only be produced at high temperature
Thermal deformation, and its intensity can also reduce, and reduce the service life of equipment, lubrication accident occurs when serious, causes equipment to transport
Row is stuck and rests.
The thickening agent that Hmp grease is used is generally complex lithium, polyureas and silica, and complex lithium and polyureas are increasingly high
High price is brought to the use enterprise of Hmp grease greatly uses pressure, and silica is generally difficult to meet higher again
Use requirement.At present, organobentonite is gradually shown solely with its exclusive characteristic in Hmp grease with thickening agent field
Special advantage.
Bentonite grease is the important nonsoap grease of class, is to be thickened mineral lubricating oil or synthesis with modified alta-mud
High temperature lubricating fat prod prepared by lubricating oil, not only with good heat resistance, while having good mechanical stability and glue
Body stability.Heat-resisting bentonite grease and extreme-pressure bentonite grease lubricant using organobentonite as thickening agent can be answered widely
For general agricultural machinery, general industry machinery, it is particularly suitable for metallurgical equipment, casting and steel rolling equipment, mine heavy-duty machinery is set
The fields such as standby, large-scale truck, papermaking equipment, cement manufacture plant, high temp tunnel kiln car.In addition, bentonite grease
Occupy critical role in aviation grease product.
The content of the invention
It is an object of the invention to provide a kind of Hmp grease thickening thickening agent.
To achieve these goals, the present invention uses following technical scheme：
A kind of Hmp grease thickening thickening agent, it is characterised in that be prepared from by following methods：
(1) by sodium bentonite under the conditions of 350~450 DEG C calcination 1h；
(2) prepare mass fraction be 17~19% sulfuric acid solution, add step (1) obtain bentonite, bentonite with
The solid-liquid mass ratio of sulfuric acid solution is 2.10~2.30:30min is stirred under the conditions of 1,95~100 DEG C and carries out acidification reaction, is flocculated,
Slagging-off, filtering；
(3) material for obtaining step (2) is introduced into standing groove, adds washings, is stirred 1~2 minute, time of repose
45min, extracts supernatant liquor, and cyclic washing 4~9 times is 4~5 to clear liquid pH value, filtered, drying；
(4) bentonite for obtaining step (3) is put into ball mill, is ground 4h under 40KHz ul-trasonic irradiation, is obtained super
Thin bentonite；
(5) m is pressedBentonite：mCoverture=100：The Ultra-fine Bentonite that 0.1~0.15 ratio obtains step (4) adds quality
Fraction for 35~45% organic covering agent solution in, stir 2h under the conditions of 80 DEG C；
(6) by the material obtained by step (5) through flocculation, filtering is dried under the conditions of being transferred to 30 DEG C, and 200 are crossed after milling
Mesh sieve, obtains Hmp grease thickening thickening agent.
Further, the quality of step (3) described washings obtains 6 times of quality of material by step (2).
Calcination temperature described in step (1) is 380 DEG C.
Organic coverture described in step (5) is dimethyl stearyl hexadecyldimethyl benzyl ammonium.
Obtained Hmp grease thickening can be applied to prepare Hmp grease with thickening agent according to the method described above.
The specific steps of the above method are further described below：
1. calcination bentonite.Sodium bentonite is subjected to calcination at a certain temperature, removes a part of interlayer in bentonite
Water and water is combined, increase bentonite bedding void, make its loose.Temperature is suitable, it is ensured that removes intermediary water and combines water, and not
Can be too high and bentonite is sintered.Suitable temperature is 350~450 DEG C, preferably 380 DEG C.
2. acid activation.The sulfuric acid solution of certain mass fraction is prepared, adding step (1) by certain solid-liquid mass ratio obtains
Bentonite, stirring 30min carries out acidification reaction under the conditions of 95~100 DEG C, flocculates, and removes the gred, filtering.The quality of sulfuric acid solution point
Number is 17~19%, and the solid-liquid mass ratio of bentonite and sulfuric acid solution is 2.10~2.30:1.
3. clean spent acid.The material that step 2 is obtained is introduced into standing groove, adds a certain amount of water, is stirred 1~2 minute,
Time of repose is 45min, extracts supernatant liquor out, and cyclic washing to clear liquid pH value is 4~5, is filtered, drying.The quality of water is step
Rapid 2 obtain 6 times of quality of material.
4. ultrasonic grind.The bentonite that step 3 is obtained is put into ball mill, is ground under 40KHz ul-trasonic irradiation
Grind 4h.Obtain Ultra-fine Bentonite.
5. organic coverture covering.The Ultra-fine Bentonite that step 4 is obtained in proportion adds the organic of certain mass fraction
Cover in agent solution, 2h is stirred under the conditions of 80 DEG C.The mass ratio of Ultra-fine Bentonite and organic coverture is mBentonite：mCoverture=100：
0.1~0.15, the mass fraction of organic coverture aqueous solution is 35~45%, and organic coverture is dimethyl stearyl benzyl
Ammonium.
6. by the material obtained by step 5 through flocculation, filtering is dried under the conditions of being transferred to 30 DEG C, and 200 mesh are crossed after milling
Sieve, obtains Hmp grease thickening thickening agent.
The present invention first by sodium bentonite calcination, add bentonitic bedding void, using sodium bentonite sun from
Sub- commutativity, by sulfuric acid activated, with the H of inorganic acid+Replace the Na between bentonite bed+, the space of structure cell is increased, is expanded
Cavity, has dredged cavity, has increased specific surface area, enhanced surface-active, added ion exchange property so that acidifying
Bentonite possesses the properties such as generation Inter layer adsorption, bonding and absorption electronic action.Meanwhile, reach the bentonitic purpose of purification.It is logical
Ultrasonic grind is crossed, bentonitic specific surface area and electronegativity is further improved.Utilize the special chemistry of quaternary ammonium salt organic matter
Structure, by intercalation modifying, forms organic covering on bentonite surface, improves bentonite for hydroxyl and carboxyl isopolarity group
With good compatibility, good thickening effect is played during Hmp grease is prepared as thickening agent.
