Abstract Details

2018, Master of Science, University of Akron, Polymer Engineering.
Torrefied sorghum (TS) is considered an attractive, eco-friendly, renewable and low cost reinforcement filler that can be used for partial or full replacement of carbon black (CB) in styrene butadiene rubber (SBR). Torrefaction is a process that uses heat in a low oxygen environment to convert plant biomass into a cleaner, renewable filler. In this research, the possibility of replacing carbon black with torrefied sorghum was investigated for concentrations of TS in reinforcement filler varying from 0 to 100%. In addition, the effects of ball mill treatment on the morphological and chemical structures of TS and properties of the filled rubber compound were also analyzed. The results showed that ball mill treatment reduced the particle size of TS and the degree of crystallinity of the cellulose in TS, while lignin was much more stable. The optimum concentration of TS in reinforcement filler was ~30% to obtain properties comparable to those obtained using CB only. These included mechanical properties and cure behavior along with higher wet-skid resistance and lower rolling resistance due to adequate filler-filler and filler-rubber interactions in the rubber matrix. Ball milled TS filled rubber compound showed higher tensile strength and strain at break but lower moduli at 2% and 100% strain compared to the untreated TS filled one.
