Description

本発明は、放熱性の良い成形体が得られる熱伝導性樹脂組成物に関する。   The present invention relates to a thermally conductive resin composition from which a molded article having good heat dissipation can be obtained.

従来の高熱伝導性樹脂は、ポリフェニレンエーテル(PPS)等の弾性率が高い樹脂に熱伝導性フィラーを多量に充填したものであるため、成形品の弾性率が高く、脆いという問題があり、大型の成形品や複雑な形状の成形品には適用できなかった。また、PPSのほか、ポリカーボネート(PC)等の高温での成形が要求される樹脂をベースにすると、成形性が良くなく、やはり大型の成形品には適用できない。

Conventional high heat conductive resins are those in which a large amount of heat conductive filler is filled in a resin having a high elastic modulus such as polyphenylene ether (PPS), so that there is a problem that the elastic modulus of the molded product is high and brittle. It could not be applied to the molded product of the above and the molded product of complicated shape. In addition to PPS, if a resin such as polycarbonate (PC) that requires molding at a high temperature is used as a base, moldability is not good and it cannot be applied to a large molded product.
