<p>The invention provides a foamable styrene series resin particle with good antistatic property. A preparing method is characterized in that under the existence of surface active agents, when the foaming agent is soaked in the styrene series resin particles to generate foamable resin particles, compared with 100 by weight styrene series resin particles, 1-4 by weight surfactants are used; the surfactant comprises positive ion surfactant whose weight ratio is 1:0.03-0.8 and non-aqueous nonionic surfactant. The invention also provides prefoaming particles obtained from prefoaming the foamable styrene series resin particles, and a foam molding body formed by foaming the prefoaming particles.</p> |
