Polycarbonate resin composition and molded article produced therefrom

摘要

The polycarbonate resin composition includes: a polycarbonate component, which includes an aromatic polycarbonate resin and a copolymerized polycarbonate resin including a repeat unit represented by Formula 1 and a repeat unit represented by Formula 2; and a flame retardant, and has a scratch width of about 310 μm or less as measured by Ball-type Scratch Profile (BSP) test; a pencil hardness rating of F or higher; a flame retardancy level of V-0 or higher as measured on a 2.0 mm thick specimen according to UL94; and a transmittance of about 80% or more as measured in accordance with ASTM D1003. The polycarbonate resin composition can exhibit excellent properties in terms of scratch resistance, flame retardancy and transparency.;wherein R1 and R2 are the same or different and are each independently substituted or unsubstituted C1 to C6 alkyl, and a and b are the same or different and are each independently an integer from 1 to 4.

1. A polycarbonate resin composition comprising:
a polycarbonate component, which comprises an aromatic polycarbonate resin and a copolymerized polycarbonate resin comprising a repeat unit represented by Formula 1 and a repeat unit represented by Formula 2; and a flame retardant, wherein the polycarbonate component comprises the aromatic polycarbonate resin in an amount of about 30 wt % to about 70 wt % and the copolymerized polycarbonate resin in an amount of about 30 wt % to about 70 wt %, wherein, in the copolymerized polycarbonate resin, the repeat unit represented by Formula 1 is present in an amount of about 5 mol % to about 70 mol % and the repeat unit represented by Formula 2 is present in an amount of about 30 mol % to about 95 mol %, and the polycarbonate resin composition having: a scratch width of 290 μm or less as measured by Ball Scratch Profile (BSP) test; a pencil hardness rating of F or higher; a flame retardancy level of V-0 or higher as measured on a 2.0 mm thick specimen according to UL94; a Vicat softening temperature (VST) of 102.5° C. or more, as measured in accordance with ASTM D1525; and a transmittance of about 85% or more as measured in accordance with ASTM D1003, wherein R1 and R2 are the same or different and each independently substituted or unsubstituted C1 to C6 alkyl, and a and b are the same or different and each independently an integer from 1 to 4.
