Document Type and Number:
Japanese Patent JP2601336
Kind Code:
B2
Abstract:
PURPOSE:To knead two or more kinds of resin being not compatible with each other, and disperse them uniformly by combining two kneading apparatus comprising a main extruding part for melting plasticization, and an auxiliary extruding part for kneading by a high shearing force and being provided with removing means for shearing heat on its outer periphery. CONSTITUTION:The tip of a main extruding part 1 is connected to the feeding part of an auxiliary extruding part 3 by way of a connecting part 2. In a cylinder of the main extruding part 1, a screw 4 is built in which is effective mainly to the melting plasticization of thermoplastic resin, and in a cylinder of the auxiliary extruding part 3, a screw 5 is attached which can knead and disperse at a high shearing force, and a water cooled direct cooling part 6, and water cooled indirect cooling part 7 are attached on its outer periphery. The thermoplastic resin melted in the main extruding part 1 is forwarded to a weak compression part 5b by way of the connecting part 2, and further, forwarded to a high shearing part 5c, and then kneaded and dispersed uniformly while being cooled therein.
