EXPANDABLE STYRENE POLYMER COMPOSITION HAVING GOOD FLAME RETARDANCY, FLAME RETARDANT POLYSTYRENE FOAM AND METHOD FOR PREPARING FLAME RETARDANT POLYSTYRENE FOAM

摘要

PURPOSE: A method for preparing an expandable polystyrene resin composition is provided to prevent melting and degradation of strength while effectively coating inorganic compounds such as expanded graphite. CONSTITUTION: An expandable polystyrene resin composition with excellent flame retardancy is coated with expandable polystyrene particles. The flame retardant composition includes 100.0 parts by weight of expandable polystyrene resin, 5-100.0 parts by weight of expanded graphite, 50-200 parts by weight of liquid binder, and 15-50 parts by weight of styrene-based compatibilizer.
