廃タイヤの脱硫反応条件と再加硫ゴム物性 CONTINUOUS DEVULCANIZATION BY SHEAR FLOW STAGE REACTION CONTROL TECHNOLOGY FOR RUBBER RECYCLING, PART 5. DEVULCANIZATION CONDITION AND MECHANICAL PROPERTIES OF REVULCANIZED RUBBER FOR USED TIRE WASTE
Continuous devulcanization by shear flow stage reaction control technology for sulfur vulcanized EPDM rubber has been developed. In this study, this technology has been applied for the devulcanization of rubber tire consisting of NR/SBR which has been used in practice. By optimizing devulcanization conditions such as reaction temperature, screw rotation and addition of process oil, devulcanized rubber can be extruded continuously. The devulcanized rubber can be revulcanized by conventional curing process with sulfur-accelerator vulcanizing system. The revulcanized rubber shows good mechanical properties which meet JIS K6313 standard.
