Styrene-butadiene rubber mixtures with four types of carbon black were studied in this paper. The mechanical properties, including the ability to damp mechanical vibration, were investigated, along with dynamical mechanical analysis (DMA). It has been found that carbon black types N 110 and N 330, having the largest specific surface area and the smallest particle diameter, provide a good stiffening effect. These particles have significant interactions between the rubber, resulting in good reinforcement. On the other hand, the carbon black N 990 type has a lower reinforcing effect and improved vibration damping properties at higher excitation frequencies due to higher dissipation of mechanical energy into heat under dynamic loading. The effect of the number of loading cycles on vibration damping properties of the rubber composites was also investigated in this study. It can be concluded that the abovementioned properties of the investigated rubber composites correspond to physical-mechanical properties of the applied carbon black types.
本文研究了含有四种炭黑的丁苯橡胶混合物。研究了其机械性能,包括阻尼机械振动的能力,并进行了动态力学分析(DMA)。已发现,比表面积最大且粒径最小的N 110型和N 330型炭黑具有良好的增强效果。这些颗粒与橡胶之间存在显著相互作用,从而产生良好的增强作用。另一方面,N 990型炭黑的增强效果较低,但由于在动态载荷下机械能向热的耗散较高,在较高激励频率下具有改善的减振性能。本研究还考察了加载循环次数对橡胶复合材料减振性能的影响。可以得出结论,所研究的橡胶复合材料的上述性能与所应用炭黑类型的物理机械性能相对应。
