It is a kind of.
Preferably, the attapulgite is that acid activation is attapulgite modified.
The acid activation is attapulgite modified the preparation method comprises the following steps: that attapulgite is calcined to 4-5 at 300-400 DEG C is small
When, powder is taken out, 10-100 mesh is crossed, is added to the water stirring (attapulgite 1-20g can be added in 100mL water), obtains bumps
Stick suspension；It is 3~4 that salt acid for adjusting pH value, which is added, to concave convex rod suspension, stirs at 50-60 DEG C 1-2 hours, then adds again
Entering NaOH to adjust pH value is 6.5~7.5, and stirring is filtered after 1-2 hours, is finally washed with water and (can repeatedly be washed), after
It is filtered dry dry, it is attapulgite modified to obtain acid activation.Specifically, the hydrochloric acid solution of 1mol/L and the NaOH solution of 1mol/L can be added
The pH value of concave convex rod suspension is adjusted.
The preparation method of the present invention also provides the described coating water treatment agent containing attapulgite, this method include such as
Lower step:
Step 1, the pH value for being adjusted with acid water is 3-4, is then respectively adding polysilicon acid magnalium, thickener, attapulgite, infiltration
Saturating agent and surfactant are stirred dissolution, until being completely dissolved, obtain solution Ι；The composition of each component by weight percentage
Are as follows: water 80-88%, attapulgite 4-8%, polysilicon acid magnalium 3-5%, bleeding agent 1-2%, surfactant 1-2%, thickener
1-3%.
Step 2, the pH value for adjusting previous solu Ι with aqueous slkali obtains the coating water treatment agent to neutrality.
Preferably, in the preparation method of the coating water treatment agent: the attapulgite is that acid activation is attapulgite modified；
The bleeding agent is selected from diisooctyl maleate sulfonate or fatty alcohol polyoxyethylene ether；The surfactant is selected from ten
