To provide a urethane foam molded product having high thermal conductivity and electric insulation and a method for producing the same. A urethane foam molded product includes a base material made of a polyurethane foam and composite particles that are blended in the base material and oriented in a mutually connected state, in which each of the composite particles includes a thermally conductive particle made of a non-magnetic body, and a magnetic particle and an insulating inorganic particle that are adhered to the surface of the thermally conductive particle through a binder. A powder of the composite particles can be produced by stirring a powder raw material containing a powder of the thermally conductive particle, a powder of the magnetic particle, a powder of the insulating inorganic particle, and the binder using a stirring granulator. The urethane foam molded product is produced by injecting a mixed raw material in which the powder of the composite particles and a foamable urethane resin raw material are mixed into a cavity of a foaming mold and performing foam molding with applying a magnetic field to the mixed raw material so that the magnetic flux density in the cavity is substantially homogeneous. |
