A non-halogen flameproof polycarbonate resin composition of the present invention comprises (A) about 30 to about 100% by weight of a polycarbonate resin, (B) about 0 to about 70% by weight of a rubber modified aromatic vinyl resin, and (C) about 0.5 to about 30 parts by weight of a phosphorus compound represented by the following Chemical Formula (I) or a combination thereof, based on about 100 parts by weight of the base resin including (A) and (B). The present invention can provide a polycarbonate resin composition which can have excellent flame retardancy and which can be environmentally friendly. wherein R1 and R2 are each independently C1 to C10 alkyl, C5 to C7 cycloalkyl or phenyl.
摘要:
A non-halogen flameproof polycarbonate resin composition is disclosed. The polycarbonate resin composition includes a base resin including (A) about 50 to about 100% by weight of a polycarbonate resin, (B) about 0 to about 50% by weight of a rubber modified aromatic vinyl resin, and (C) about 0 to about 50% by weight of an alkyl(meth)acrylate resin; and (D) about 0.5 to about 30 parts by weight of a cyclic t-butyl phosphonate compound, based on about 100 parts by weight of the base resin comprising (A), (B) and (C). The polycarbonate resin composition can have stability against fire and can be environmentally friendly since it does not contain a halogen flame retardant.
