Abstract
The invention discloses a method for preparing a dispersing agent used for grinding an inorganic mineral. The method comprises the steps as follows: (1), mixed monomers accounting for 10%-20% of the total weight of mixed monomers and an initiating agent accounting for 10%-20% of the total weight of initiating agents are added into water for a mixed reaction to form prepolymer; (2), a molecular weight modifier and a composite surface active agent are added into the prepolymer, then, remaining mixed monomers and initiating agents are dropwise added simultaneously for 3-5 hours at the temperature in a range from 85 DEG C to 105 DEG C, and the reaction is performed for 1-2 hours after the dropwise adding is finished; and (3), the temperature is decreased to 40 DEG C-50 DEG C after the reaction is finished, and the PH value is neutralized to 7-9 by a sodium hydroxide solution. The prepared dispersing agent can be used as a specific dispersing agent for grinding the inorganic mineral with a wet method, so that agglomeration of particles can be reduced, the grinding time is shortened, the dispersibility is good, the solid content of slurry is high, and the viscosity is low.
