［産業上の利用分野］
本発明は、電子・電気機器の筐体等に有効な電磁波シー
ルド性を有する導電性熱可塑性樹脂組成物に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a conductive thermoplastic resin composition having electromagnetic shielding properties that are effective for use in housings of electronic and electrical equipment, and the like.
［従来の技術とその課ＷＪ］
近年、電子機器、ＯＡ機器等のプラスチック化に伴ない

合化させる方法がある。[Prior art and its section WJ] In recent years, as electronic equipment, OA equipment, etc. have become plastic, electromagnetic waves emitted from these equipment have caused malfunctions of peripheral equipment, which has become a major problem. As a method for preventing this electromagnetic interference, there is a method of forming a conductive coating layer on the surface of the molded product by painting, plating, thermal spraying, or the like. There is also a method of blending and dispersing a conductive material into a molded product.
しかし、前者の方法によるものでは、成形品表面の導電

り、シールド性も含めた信頼性が十分だとはいえない。However, in the former method, there is a risk that the conductive coating layer on the surface of the molded product may peel off or fall off, and reliability including shielding performance cannot be said to be sufficient.
一方、後者の方法によるものでは、熱可塑性樹脂中に導

とが示されている。On the other hand, in the latter method, methods of combining a large number of conductive materials with a thermoplastic resin have been studied. For example, JP-A-58-176220 discloses that in order to easily mix and knead metal fibers into a thermoplastic resin, the metal fibers are preliminarily concentrated in a thermoplastic resin solution or emulsion.

に配合することはできない。When compounding a conductive material into a thermoplastic resin, if a large amount of the conductive material is blended, although the conductivity improves, moldability and the like deteriorate. On the other hand, if a conductive material is mixed in a small amount, it is difficult to ensure sufficient conductivity by uniformly mixing the material by adjusting the orientation of the fibers during molding. Further, even when an inorganic filler is blended in order to blend a small amount of conductive material, it is not possible to blend a large amount of the inorganic filler because moldability and the like deteriorate.
本発明は、かかる点に鑑みてなされたものであり、導電

In order to make the thermoplastic resin into an island part, it is sufficient to satisfy the following conditions.
