FIREPROOF STYRENE-BASED THERMOPLASTIC RESIN COMPOSITION CONTAINING SPECIFIC FLAME RETARDANT AND FLAME RETARDANT AUXILIARY AND POLYETHYLENE CHLORIDE

摘要

PURPOSE: A fireproof styrene-based thermoplastic resin composition is provided, to improve fire resistance without the deterioration of mechanical properties and processability by using specific flame retardant and flame retardant auxiliary and polyethylene chloride. CONSTITUTION: The fireproof styrene-based thermoplastic resin composition comprises 100 parts by weight of a resin mixture comprising 10-70 parts by weight of a rubber modified styrene-containing graft copolymer and 10-60 parts by weight of a styrene-containing copolymer; 1-30 parts by weight of at least one flame retardant selected from the group consisting of a halogen compound, a phosphorus-based compound and an epoxy compound; 20-25 parts by weight of at least one flame retardant auxiliary selected from the group consisting of antimony oxide, a zinc compound, barium borate, zirconium oxide, talc and mica; and 1-10 parts by weight of polyethylene chloride.
