PRODUCTION METHOD FOR POWDER, PRODUCTION METHOD FOR MELT-MOLDED ARTICLE, POWDER, COMPRESSION-MOLDED ARTICLE, AND MELT-MOLDED ARTICLE

摘要

One of the purposes of the present invention is to provide a production method that makes it possible to obtain a powder that makes it possible to suppress foaming of a molten material and to produce a molded article that has favorable conductivity and a favorable appearance by melt molding. A production method for a powder that includes a composite resin (2, 21, 22, 23) that includes a hot-melt resin (2a) and a conductive filler (2b). The production method for a powder comprises the following steps. A step for preparing a dispersion by mixing: a raw material powder that includes the hot-melt resin (2a); the conductive filler (2b); a dispersion medium in which the raw material powder and the conductive filler (2b) can be dispersed; and a dispersant (3) that makes the conductive filler (2b) disperse in the dispersion medium. A step for removing the dispersion medium from the dispersion and recovering an intermediate powder that includes the composite resin (2, 21, 22, 23) and the dispersant (3). A step for removing the dispersant (3) from the intermediate particles.
