MULTI-SCREW KNEADER AND METHOD FOR PRODUCING NANO-COMPOSITE USING SAID MULTI-SCREW KNEADER, AND DISK-SHAPED SEGMENT USED FOR SAID KNEADER AND SAID METHOD

摘要

Provided are a multi-screw kneader that can sufficiently exhibit an extensional flow function functioning before and behind small holes of a disk-shaped segment having the small holes and a method for producing a nano-composite using the multi-screw kneader and a disk-shaped segment to be used therein. The multi-screw kneader of the present invention includes a plurality of kneading screws and a disk-shaped segment in a barrel. The disk-shaped segment partitions the inside of the barrel downstream a part for charging a kneading material and includes a plurality of shaft penetrating parts through which rotating shafts of the kneading screws rotatably pass and a large number of small holes punched in a periphery of these shaft penetrating parts and serving as flow channels of the kneading material. The method for producing a nano-composite of the present invention includes a step of charging nanoparticles as a resin additive using the multi-screw kneader. The disk-shaped segment of the present invention includes the shaft penetrating parts and the large number of the small holes.
