METHOD AND DEVICE FOR EXTRUSION AND EXTRUDED PRODUCT THEREBY

摘要

PURPOSE: To provide an extrusion molding method capable of obtaining a useful product by using waste tires, an apparatus for the method, and an extruded molding by the method. CONSTITUTION: An apparatus is composed of an extruder 30, a transition nozzle 46 having an outlet of a cross section corresponding to the desired cross section of a useful product, a molding chamber 58 formed to remove heat energy from the inner surface. The heated mixture of a crushed entire waste tire 12 and a thermoplastic binder material 16 is extruded continuously into the cooled chamber 58 through the extruder 30 and the nozzle 46. A molding extruded from the chamber 58 is cut in a prescribed size.
