This study analyzes the effects of rotor speed, mixing time, and initial temperature on the curing characteristic, mechanical and dynamical properties, as well as the morphology of nanostructured silica/natural rubber composites. The rotor speed, mixing time, and initial temperature settings of the mixer were adjusted in the range of 40–100 rpm, 15–24 min, and 80–100 °C, respectively. Furthermore, a combination of good dispersion with a moderate mastication effect was used to obtain the vulcanizate's good mechanical properties and prevent premature crosslinking. The result showed that at a rotor speed of 60 rpm, excessive rubber degradation occurred at the compounding time of more than 21 min, while at the compounding time of 24 min, it occurred at rotor speeds of more than 40 rpm. Meanwhile, premature crosslinking occurred at an initial mixing temperature of 100 °C, with a velocity gradient in the range of 8.2–11.3 s⁻¹ providing excellent reinforcement of natural rubber composite by nanostructured silica from bagasse ash.

这项研究分析了转子速度，混合时间和初始温度对硫化特性，机械和动力学性能以及纳米结构二氧化硅/天然橡胶复合材料形态的影响。混合器的转子速度，混合时间和初始温度设置分别在40–100 rpm，15–24分钟和80–100°C的范围内进行调整。此外，结合了良好的分散性和适度的咀嚼效果，从而获得了硫化胶的良好机械性能并防止过早交联。结果表明，在60 rpm的转子转速下，超过21 min的混合时间橡胶过度降解，而在24 min的混合时间内，超过40 rpm的橡胶降解过度。同时，^-1通过甘蔗渣灰的纳米结构二氧化硅为天然橡胶复合材料提供了出色的补强效果。
