Inorganic fillers (mainly obtained from residue recycling/reuse operations) have been widely used as an alternative reinforcement in polymer composites to replace commercial silica. In this study, we analyze the interaction between Sugarcane Bagasse Ash (SCBA) and natural rubber using Bis[3-(triethoxysilyl)propyl] Tetrasulfide (TESPT) as the silane coupling agent and Tetramethylthiuram Disulfide (TMTD) as the curing alternative system. Based on the results, we were able to validate their influence on the physical properties of the obtained composites. In particular, the coupling agent used in this study led to an improved interaction between SCBA and the polymer matrix, which was corroborated by the resulting mechanical response (stress–strain tests) and DMA (tensile strength) characterizations. Therefore, these findings encourage further research to explore a process at the industrial level to reuse SCBA waste and, thus, contribute to the protection of the environment.

甘蔗渣粉在橡胶工业中的潜在生态友好应用

无机填料(主要从残留物回收/再利用操作中获得)已广泛用作聚合物复合材料中的替代增强材料,以取代市售二氧化硅。在这项研究中,我们使用双[3-(三乙氧基甲硅烷基)丙基]四硫化物(TESPT)作为硅烷偶联剂和四甲基秋兰姆二硫化物(TMTD)作为固化替代体系,分析了甘蔗渣(SCBA)和天然橡胶之间的相互作用。根据结果​​,我们能够验证它们对所得复合材料物理性能的影响。特别是,本研究中使用的偶联剂改善了SCBA与聚合物基体之间的相互作用,这由所得到的机械响应(应力-应变测试)和DMA(拉伸强度)表征所证实。因此,
