Abstract

The present invention relates to a high flame-retardant method for an expandable polystyrene widely used as a heat insulating material, and to a device therefore, in which a loess flame-retardant solution mixed with fine loess powder is compulsorily injected to a molded expandable polystyrene and dried to be fixed onto the expandable polystyrene, to thereby obtain a high flame-retardant expandable polystyrene form which is close to a semi-nonflammable material.
