<p>The present invention relates a method for manufacturing flame-retardant expanded polystyrene particles and a method for manufacturing a flame-retardant expanded polystyrene board and includes a step of manufacturing a first coating solution by mixing and stirring water, sodium compounds, feldspar powder, talc powder, silica powder, diatomite, zinc oxide, PVAc, methanol, and MEK; a step of manufacturing flame-retardant expanded polystyrene by spraying 1-8 wt% of the first coating solution on 100 wt% of expanded polystyrene particles to be coated; a step of manufacturing a second coating solution by mixing and stirring feldspar powder, talc powder, sodium silicate, PVAc, and EVA; a step of manufacturing a flame-retardant expanded polystyrene foamed body by foaming the flame-retardant expanded polystyrene particles; a step of spraying 60-200 wt% of the second coating solution on 100 wt% of flame-retardant expanded polystyrene foamed body to be coated; a step of drying the fluidized bed of the flame-retardant expanded polystyrene foamed body on which the second coating solution is coated; and a step of manufacturing a flame-retardant expanded polystyrene board by aging the foamed body after the fluidized bed is dried and molding the foamed body under steam.
