<p>The present invention relates to flame-retardant expanded polystyrene using a liquefied material obtained through an inorganic substance and, more specifically, to flame-retardant expanded polystyrene using a liquefied material obtained through an inorganic substance, which is manufactured through an expanded process of mixing 3-6 parts by weight of a liquefied material and 9-11 parts by weight of water, wherein the liquefied material is obtained by melting, extracting and liquefying star stone as an inorganic substance which contains: 73-75 parts by weight of silicon dioxide, 14-16 parts by weight of aluminum oxide, 0.8-1.1 parts by weight of iron oxide, 0.08-0.1 parts by weight of calcium oxide, 0.1-0.3 parts by weight of magnesium oxide, 3-5 parts by weight of potassium oxide, 1-2 parts by weight of sodium oxide, 0.03-0.05 parts by weight of titanium dioxide, 0.01-0.03 parts by weight of manganese oxide, and 0.01-0.03 parts by weight of phosphorus pentoxide, with respect to 100 parts by weight of an expanded polystyrene particle. According to the present invention, flame-retardant expanded polystyrene can be expected to have light weight and excellent flame resistance, without separately adding a catalyst.</p> |
