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：
