POLYCARBONATE RESIN COMPOSITION

摘要

The present invention relates to a polycarbonate resin composition which has low warpage property and excellent flowability and appearance properties, and exhibits more improved toughness.;The polycarbonate resin composition includes 35 to 60% by weight of a polycarbonate resin; 30 to 55% by weight of a glass fiber having a square or oval cross-sectional shape in the direction perpendicular to the longitudinal direction, in which its aspect ratio of the following Formula 1 is 50 to 200; 1 to 10% by weight of an impact modifier having a core-shell structure; 1 to 10% by weight of an ethylene-(meth)acrylate-based copolymer; and 1 to 10% by weight of a rheology modifier containing a thermoplastic polyester-based polymer or a phosphate ester-based compound.

1. A polycarbonate resin composition, comprising:
35 to 60% by weight of a polycarbonate resin; 30 to 55% by weight of a glass fiber having a square or oval cross-sectional shape in the direction perpendicular to the longitudinal direction, in which its aspect ratio of the following Formula 1 is 50 to 200; 1 to 10% by weight of an impact modifier having a core-shell structure; 1 to 10% by weight of an ethylene-(meth)acrylate-based copolymer; and 1 to 10% by weight of a rheology modifier containing a phosphate ester-based compound:
Aspect ratio (δ)=L/D  [Formula 1] wherein L is the length of glass fiber, and D is the length of the longest side of the square cross section or the length of the longest diameter of the oval cross section.
