FLAME RETARDANT STYRENE RESIN COMPOSITION HAVING HIGH FLUID STYRENE AND DIENE RUBBER BLOCK COPOLYMERS

摘要

PURPOSE: Provided is a flame retardant styrene resin composition which includes styrene and diene rubber block copolymers with high fluidity as a shock reinforcing agent with improving the appearance of the projected products. CONSTITUTION: The flame retardant styrene resin composition comprises: (A) 85-99 wt% of rubber modified styrene copolymers; (B) 1-15wt% of styrene and diene rubber block copolymers with 1.5-15 times higher fluidity than the rubber modified styrene copolymers as an impact resistant material; (C) on a basis of 100wt% of styrene resin composed of (A) and (B), 4-25wt% of halogen flame retardant agents; and (D) on a basis of 100wt% of styrene resins composed of (A) and (B), 0.5-10wt% of flame retardant auxiliary agents.
