| description | A study on the effect of mixing process parameters of nanostructured silica/SBR composite on cure characteristics, mechanical properties, morphology, and vulcanization kinetics was performed. The mixing process was carried out in an internal mixer with 3 (three) investigated parameters, namely: initial mixing temperature (70 - 100°C), mixing time (6 - 21 min.), and rotor speed (40 - 100 rpm). At rotor speed 60 rpm, the higher the initial mixing temperature, the lower the percent agglomeration of silica particles, but at 100°C the percent agglomeration is high due to premature crosslinking. Meanwhile, the higher the initial mixing temperature the higher the tensile strength. The longer the mixing time, the lower the percent agglomeration because the silica is more dispersed, but the tensile decreases due to the influence of polymer degradation due to mastication. At initial mixing temperature 80°C, the higher the rotor speed the better the dispersion, the greater the bound rubber, but at 100 rpm the percent agglomeration is high due to premature crosslinking. Meanwhile, the higher the rotor speed the higher the tensile strength. At mixing time 15 min. selection of the rotor speed and initial temperature of the mix can be adjusted according to the desired mechanical properties with a velocity gradient in the range of 7.31-11.47 s-1. The vulcanization kinetics study was then applied to the compounds that were previously mixed at various initial mixing temperature. It was found that the higher the initial mixing temperature of the compound, the lower its activation energy. © 2022 Author(s). |
