The invention relates to a
graphite EPS bead and a production technology thereof. Through the steps of preparing materials, feeding, cooling and plastifying,
voltage stabilization and transportation, shaping and bead
cutting, dehydrating, sieving, packaging and the like,
polystyrene granules, foaming agents,
graphite powder with modified surfaces, and fire retardants are mixed to obtain the
graphite EPS bead. The
polystyrene and other raw materials are directly selected for reaction, the time of the
polymerization reaction is shortened, the impurities generated by the incomplete
polymerization reaction are reduced, and the quality of products is improved. For the production technology disclosed by the invention, the raw materials of the
polystyrene, the graphite
powder, the fire retardants and the like are firstly melt, then the liquid foaming agents are added, and the foaming agents and melt bodies are uniformly mixed, so that the quality of the products is ensured, the quality of the products is stable, the
granularity is uniform, the foaming rate of the products is ensured, and the production cost is reduced. The production technology is suitable for popularization and usage.
