| Abstract: | The desulfurization promoter polyalkyl phenol disulfide(simplified 420) or/and secondary butyl alcohol as promoting agent were added during the melt extrusion of ground tire rubber and ethylene-propylene-diene monomer rubber(EPDM).The effects of the promoter on the gel content and sol molecular chain of the devulcanized blends(DGTR/EPDM) were investigated at different screw speed and extrusion temperature.The morphology structure and mechanical properties of recured DGTR/EPDM/styrene-butadiene rubber(SBR) b... |
