Beschreibung
Zusammenfassung:	The invention discloses a preparation method of a novel dispersant, which comprises the steps of: taking crylic acid as a main reaction monomer; adding at least one of monomers such as methacrylic acid, maleic anhydride, fumaric acid, itaconic acid and methyl sodium allylsulfonate as comonomer; taking r-methacryloxypropyl trimethoxy silane, vinyl trimethoxy silane or vinyl triethoxysilane as organic silicon monomer to participate in polymerization; taking a redox system as an initiating system; and polymerizing by water solution, and neutralizing by alkaline substance to obtain the novel dispersant. Due to the novel dispersant, the grinding of calcium carbonate has the characteristics of being low in sizing agent viscosity, small in grain size, good in dispersibility and high in stability.
