CONDUCTIVE RESIN COMPOSITION FOR MOLDING AND ELECTROMAGNETIC SHIELD STRUCTURE

摘要

PURPOSE:To manufacture a structure of superior electromagnetic function by coating a conductive fiber composition for giving electromagnetic shield function with thermoplastic resin or a filling material composite plastic resin of given heat deformation temperature range in one direction and using a conductive fiber composite resin composition of two kinds or more of pellet-shaped compositions of given length. CONSTITUTION:A conductive fiber is a metallic fiber or metal coated fiber and constituted at least of two kinds of thermoplastic resin of 80-210 deg.C heat deformation temperature are used. A continuous conductive material line constituted of metallic bundle fibers is manufactured by using said conductive fiber and thermoplastic resin or thermoplastic resin including the filler and setting a crosshead in an extruder and being constituted of said thermoplastic resin is cut into the given length of 3-10mm to manufacture column-shaped pellets. A casing for an electronic instrument can be molded by using said pellets of given length and an ordinary injection molding material.
