METHOD AND DEVICE FOR MANUFACTURING ALLOY EXTRUDED MOLDING, AND EXTRUDED MOLDING

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing extruded moldings, in which in case of extruding both an alloy constituted of ethylene,α-olefin, nonconjugated polyene copolymer rubber and a crystalline polyolefin resin and various rubber compounding agents, particle diameter of a resin particle held by the alloy and an aspect ratio are maintained nearly intactly and good morphology of the resin particle is held. SOLUTION: In the manufacturing method, a blended body containing the alloy and various rubber compounding agents is extruded and thereafter the molded body is vulcanized. Furthermore, before an external force is added thereto, the vulcanized molded body is cooled at temperature lower than crystallization temperature of a polyolefin resin -20 deg.C.
