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 in which extension and flow actions which act before and after small holes in a disk-shaped segment having the small holes can be sufficiently exhibited; a method for producing a nano-composite using the multi-screw kneader; and a disk-shaped segment used for said kneader and said method. This multi-screw kneader is provided with a plurality of kneading screws and a disk-shaped segment in a barrel. The disk-shaped segment partitions the inside of the barrel at a downstream side from a kneading material feeding part, and is provided with: a plurality of shaft penetrating sections through which the rotation shaft of each kneading screw pass in a rotatable manner; and a plurality of small holes which are perforated around the shaft penetrating sections and serve as flow passages for the kneading material. This method for producing a nano-composite includes a step of feeding nanoparticles as a resin additive by using the multi-screw kneader. This disk-shaped segment is provided with the shaft penetrating sections and the plurality of small holes.
