Heat-conductive resin composition and plastic article including the same
A thermal-conductive resin composition and a plastic article are provided. The thermal-conductive resin composition comprises about 30 to about 60% by weight of a thermoplastic resin and about 40 to about 70% by weight of a thermal-conductive filler comprising about 10% by weight or more of a thermal-conductive filler with a height-to-length ratio (length/height) of about 7,000 to about 40,000 and about 10% by weight or more of a thermal-conductive filler with a height-to-length ratio of about 10 to about 1,000.
1. A thermal-conductive resin composition comprising:
about 30 to about 60% by weight of a thermoplastic resin; and
about 40 to about 70% by weight of a thermal-conductive filler comprising about 10% by weight or more of a thermal-conductive filler with a height-to-length ratio (length/height) of about 7,000 to about 40,000 and about 10% by weight or more of a thermal-conductive filler with a height-to-length ratio of about 10 to about 1,000.
2. The composition according to claim 1 , wherein the thermoplastic resin comprises a polyethylene resin, a polypropylene resin, a polystyrene resin, a styrene-butadiene copolymer resin, a polyamide resin, a polycarbonate resin, a liquid crystal polymer resin, a polyvinylidene fluoride resin, polyphenylene sulfide resin, or a combination thereof.
3. The composition according to claim 1 , wherein the thermal-conductive filler comprises aluminum nitride, boron nitride, carbon black, graphite, metallic fillers, or a combination thereof.
4. The composition according to claim 1 , wherein the volume of the thermal-conductive filler is about 60% or less of the total volume of the thermal-conductive resin composition.
5. A plastic article, which is manufactured using the thermal-conductive resin composition according to claim 1 .
6. A plastic article comprising:
a thermoplastic resin substrate; and
a thermal-conductive filler dispersed in the thermoplastic resin substrate, wherein the thermal-conductive filler comprises a thermal-conductive filler with a height-to-length ratio of about 7,000 to about 40,000 and a thermal-conductive filler with a height-to-length ratio of about 10 to about 1,000.
