Method of fabricating insulating resin material

摘要

The present invention relates to a method of fabricating an insulating resin material (4) from a core/shell particle (3) having a core particle (2) containing a macromolecular compound and a shell layer (1) coating the core particle (2) and containing an inorganic compound. The method of fabrication includes mixing the core/shell particles (3) with a good solvent (10) for the macromolecular compound, infiltrating the good solvent (10) through the shell layer (1), impregnating the good solvent (10) into the macromolecular compound, molding a compact from the impregnated core/shell particles (3), and removing the good solvent from the compact by heating the molded compact.

1. A method of fabricating an insulating resin material from core/shell particles each having a core particle containing polystyrene and a shell layer coating the core particle and containing an inorganic compound, the method comprising:
a step of mixing the core/shell particles with benzene, toluene, or xylene, infiltrating the mixed benzene, toluene, or xylene into an inside of each of the core/shell particles through the shell layer, and impregnating the polystyrene with the mixed benzene, toluene, or xylene; a step of molding a compact from the core/shell particles after the impregnation; and a step of removing the impregnated benzene, toluene, or xylene from the compact by drying the molded compact.
