The invention discloses a kind of artificial modification's sodium-ionized bentonite preparation methods, include the following steps：The bentonite material of exploitation is put into container plus water is stirred into muddy, NaCl stirrings are added in after then standing；NaCl is added in after standing 0.5h again and sulfuric acid solution is stirred, and is finally stood again；It takes out after then container is heated, is then washed with steaming pomegranate water by bentonite is taken out to neutrality；Bentonite with sodium salt is mixed, 1 3h is dried after soaking, obtains sodium-ionized bentonite semi-finished product；By sodium-ionized bentonite semi-finished product and tackifier, synergist, mix lubricant obtains sodium-ionized bentonite；By sodium-ionized bentonite and modifying agent by a certain percentage, it completes to force heating mixing, squeeze out, crushed after cooling, artificial modification's sodium-ionized bentonite product is made.The present invention provides a kind of artificial modification's sodium-ionized bentonite preparation method, the modification sodium-ionized bentonite of preparation has the characteristics that preferable thixotropy, lubricity, thermal stability, higher plasticity, stronger caking property, hot green tensile strength and dry compression are high, disclosure satisfy that all kinds of production requirements.
Description
Technical field
The present invention relates to a kind of bentonite preparation method more particularly to a kind of artificial modification's sodium-ionized bentonite preparation methods.
Background technology
The bentonite resource in China is extremely abundant, and most of bentonite ore is based on calcium-base bentonite, and grade is low
Calcium-base bentonite occupies the majority；The reserves of sodium bentonite are less, but sodium bentonite is got well than the performance of calcium-base bentonite,
Therefore, it in order to improve the performance of calcium-base bentonite, needs to carry out sodium modification processing to calcium-base bentonite.
Invention content
The object of the present invention is to provide a kind of artificial modification's sodium-ionized bentonite preparation method, the modification sodium of preparation is swollen
Profit soil has preferable thixotropy, lubricity, thermal stability, higher plasticity, stronger caking property, hot green tensile strength and does
The characteristics of Compressive Strength is high disclosure satisfy that all kinds of production requirements.
Technical scheme of the present invention：A kind of artificial modification's sodium-ionized bentonite preparation method, which is characterized in that including following step
Suddenly：

NaCl is stirred；
（2）：NaCl is added in after standing 0.5h after the completion of stirring again and sulfuric acid solution is stirred, and finally stands 1h again；
（3）：Container is then heated to 200-300 DEG C, and is taken out after heating 2-3h, is then washed with steaming pomegranate water by bentonite is taken out
It washs to neutrality；
（4）：Bentonite with sodium salt is mixed, after soaking 24-48h, 1-3h is dried under the conditions of 80-100 DEG C, obtains sodium
Bentonite semi-finished product；
（5）：By sodium-ionized bentonite semi-finished product and tackifier, synergist, mix lubricant breeds 3-5 under the conditions of 20-50 DEG C
My god, obtain sodium-ionized bentonite；
（6）：Under the heating condition no more than 100 DEG C, alkyl quaternary ammonium salts, anion surfactant are dissolved in nonionic table
It in the activating agent of face, is uniformly mixed, then by sodium-ionized bentonite and above-mentioned modifying agent by a certain percentage, the temperature of extruded stock is controlled to exist
In the range of 60-110 DEG C, complete to force heating mixing with screw extruder, squeeze out, crushed after cooling, artificial modification's sodium is made
Swelling native produce.
A kind of aforementioned artificial modification's sodium-ionized bentonite preparation method, which is characterized in that the step（1）Middle bentonite with
The dosage of NaCl is 100:10-50.
A kind of aforementioned artificial modification's sodium-ionized bentonite preparation method, which is characterized in that the step（2）Middle bentonite with
The dosage of NaCl is 100:20-50.
A kind of aforementioned artificial modification's sodium-ionized bentonite preparation method, which is characterized in that the step（6）In：Sodium is swollen
Profit soil and modifying agent sum-rate are 1.0: 0.1-1.0.
Beneficial effects of the present invention：
1st, preparation method simple possible, method is simple and easy to control, and manufacturing cost is low；
2nd, the modification sodium-ionized bentonite prepared has preferable thixotropy, lubricity, thermal stability, higher plasticity, relatively strong
