摘要： Provided is a continuous extruder including a melting and compression zone having a shaft structure of a spiral screw shape and configured to melt and compress a polymer resin and/or a secondary material which are supplied through a hopper, a dispersion zone configured to flow the molten and compressed material to a metering zone while dispersing the secondary material into the polymer resin by the actions of compression and shear stress, and an extrusion die configured to discharge a composition in which the secondary material is dispersed into the polymer resin. The dispersion zone has a shaft structure including an upwardly-tapered compression section, a straight shearing section set next to the upwardly-tapered compression section, and its length-to-diameter ratio of the shaft in the dispersion zone ranges from about 20 to about 60. Therefore, it is possible to perform in-situ processing of mixing, melting, compression, dispersion and extrusion of a layered material such as clay without a separate additional extruder, and effectively exfoliate and disperse the layered material into a polymer resin without additives such as a surfactant, a dispersing agent, an antioxidant, and a coupling agent.
