FLAME RESISTANT POLYSTYRENE PANEL WHICH IS NON-COMBUSTIBLE IN A FLAME AND MANUFACTURING METHOD THEREOF

摘要

PURPOSE: Provided is a flame resistant polystyrene panel which is non-combustible in a flame. A method for manufacturing the panel is also provided to reduce the loss of a flame retardant, thereby preventing the decrease in flame resistance. CONSTITUTION: The flame resistant foamed polystyrene panel is obtained by coating sodium silicate on the surface formed of expanded polystyrene and fusing them by using a heater. The sodium silicate may be used along with water glass. In this case, the flame resistant expanded polystyrene panel is obtained by forming an aqueous sodium silicate solution, mixing the aqueous solution with calcium carbonate, aluminum hydroxide and talc, coating the mixture on the foamed polystyrene, and fusing them by using a heater.
