Abstract

See full text

A method for preparing suspension polymerization toner of core-shell structure comprises following steps: 1) preparing a monomer oil phase containing a certain amount of polar resin forming toner soft core resin and aqueous dispersion liquid respectively; 2) adding the monomer oil phase into the aqueous dispersion liquid, transferring a mixture into a reactor after high-speed shearing and suspension granulation, and carrying out a first heating polymerization reaction to obtain toner particles of soft-core hard-shell structure; 3) taking the toner particles of soft-core hard-shell structure as a core layer, adding a cationic monomer component, and carrying out a second polymerization reaction through a water-soluble initiator to obtain the toner particles of soft-core hard-shell structure with dense charge surface layers uniformly distributed on outer surfaces; and 4) cleaning, filtering, and sufficiently drying a preceding product, and then adding silicon dioxide.
