Flame Retardant Thermoplastic Resin Composition and Molded Article Produced from the Same |
摘要 |
A flame retardant thermoplastic resin composition includes: (A) about 60% by weight (wt %) to about 90 wt % of a polycarbonate resin including a first polycarbonate having a weight average molecular weight from about 30,000 g/mol to about 50,000 g/mol and a second polycarbonate having a weight average molecular weight from about 5,000 g/mol to about 20,000 g/mol; (B) about 10 wt % to about 40 wt % of an aromatic vinyl resin having a fogging index (FI) of about 0.8 or less as calculated by Equation 1 defined in the specification; (C) about 1 part by weight to about 20 parts by weight of an impact modifier based on about 100 parts by weight of (A)+(B); and (D) about 5 parts by weight to about 30 parts by weight of a flame retardant based on about 100 parts by weight of (A)+(B. |

1. A flame retardant thermoplastic resin composition comprising:
(A) about 60 wt % to about 90 wt % of a polycarbonate resin comprising a first polycarbonate having a weight average molecular weight from about 30,000 g/mol to about 50,000 g/mol and a second polycarbonate having a weight average molecular weight from about 5,000 g/mol to about 20,000 g/mol; (B) about 10 wt % to about 40 wt % of an aromatic vinyl resin having a fogging index (FI) of about 0.8 or less as calculated by Equation 1; (C) about 1 part by weight to about 20 parts by weight of an impact modifier based on about 100 parts by weight of (A)+(B); and (D) about 5 parts by weight to about 30 parts by weight of a flame retardant based on about 100 parts by weight of (A)+(B):
Fogging index (FI)=W1/W0×100 [Equation 1] wherein W1 is a weight of unreacted monomers and oligomers deposited on a lid after placing about 10 g of an aromatic vinyl resin in a soda-lime petri dish having a diameter of about 55 mm, closing and sealing the lid, and reacting the aromatic vinyl resin at 250° C. for 20 minutes therein; and W0 is an initial weight of the aromatic vinyl resin. |
