dc.description.abstractThe waste tire rubber that had been grounded in room temperature was devulcanized by using the microwave method. As the devulcanizing agent, diphenyldisulfide (DPDS), the efficiency of which in the breaking off of sulfur bonds (S-S) had been proven in various studies, was employed. By maintaining the microwave power at a fixed value, the effects of time and the DPDS amount on the process were investigated. The untreated waste tire rubber powder was characterized physically and thermally. Composite materials were prepared with 20 phr untreated waste tire rubber powder and devulcanized rubber (DVR) with the styrene butadiene rubber (SBR) matrix. These composites were compared with a control sample that was prepared from virgin SBR. The sol content (soluble part) and Fourier Transform Infrared Spectrophotometer (FTIR) analyses of the devulcanized samples have been examined to define the efficiency of devulcanization. The mechanical properties of the SBR composites were researched. In this study, it was found that using devulcanized rubber produced much better properties than using waste tire rubber powder, thereby showing the significant benefits of microwave devulcanization. At the DPDS content of 1 g, the elongation at break of the DVR 4 min/SBR composites increased to 578% from 481% for the untreated waste tire rubber powder and SBR composites, the elongation at break was enhanced by 20% by the devulcanization of waste tire rubber powder.
