Flame retardant thermoplastic resin composition and molded article including the same
A flame retardant thermoplastic resin composition and a molded article including the same are provided. The flame retardant thermoplastic resin composition includes: (A) a thermoplastic resin; (B) a flame retardant; and (C) a filler, wherein the (C) filler has an oil absorption rate of about 0.1 ml/100 g to about 10 ml/100 g as measured in accordance with ASTM D281. With the filler having a certain range of oil absorption, the flame retardant thermoplastic resin composition can exhibit excellent stiffness and/or flame retardancy.
1. A flame retardant thermoplastic resin composition comprising:
(A) a thermoplastic resin;
(B) a flame retardant; and
(C) a filler,
wherein the (C) filler has an oil absorption rate of about 0.1 ml/100 g to about 10 ml/100 g as measured in accordance with ASTM D281.
2. The thermoplastic resin composition according to claim 1 , wherein the flame retardant is present in an amount of about 5 parts by weight to about 25 parts by weight, and the filler is present in an amount of about 1 part by weight to about 50 parts by weight, based on about 100 parts by weight of the (A) thermoplastic resin.
3. The thermoplastic resin composition according to claim 1 , wherein the (A) thermoplastic resin comprises a polycarbonate resin, polyphenylene ether resin, acrylic resin, aromatic vinyl resin, polyamide resin, polyolefin resin or a combination thereof.
4. The thermoplastic resin composition according to claim 1 , wherein the (A) thermoplastic resin comprises (A1) about 10 wt % to about 99 wt % of a polycarbonate resin and (A2) about 1 wt % to about 90 wt % of an aromatic vinyl resin.
5. The thermoplastic resin composition according to claim 1 , wherein the (B) flame retardant comprises a phosphorous flame retardant, wherein the phosphorous flame retardant includes phosphoric acid, phosphate ester compound, polyphosphate compound, red phosphorous compound, or a combination thereof; a halogen retardant; or a combination thereof.
6. The thermoplastic resin composition according to claim 1 , wherein the (C) filler comprises carbon fibers, glass fibers, glass beads, glass flakes, carbon black, talc, clay, kaolin, mica, or a combination thereof.
7. The thermoplastic resin composition according to claim 1 , wherein the (C) filler comprises talc, mica, or a combination thereof.
8. The thermoplastic resin composition according to claim 1 , wherein the (B) flame retardant and the (C) filler are present in a weight ratio (B):(C) of about 10:90 to about 90:10.
9. The thermoplastic resin composition according to claim 1 , wherein the resin composition has a flame retardancy level of V-0 or higher, and a burning time of about 30 seconds to about 50 seconds, as measured according to a UL-94 vertical flammability test method.
10. A molded article formed of the flame retardant thermoplastic resin composition according to claim 1 .
