A method for manufacture of foaming polystyrene particles comprises the steps of: dissolving styrene monomers, a styrene resin, expanded graphite, and a bulk polymerization initiator in a reactor to prepare organic phase polystyrene ; subjecting the organic phase polystyrene to bulk polymerization; mixing deionized water, a dispersant, and a surfactant to prepare an aqueous phase mixture; feeding a suspension polymerization initiator and the aqueous phase mixture to the reactor to conduct suspension polymerization to prepare polystyrene particles; and feeding a foaming agent to the reactor to prepare foaming polystyrene particles. |
