Clusia multiflora sawdust (CMS) was evaluated as filler in rubber composites. CMS at 40 phr was mixed with synthetic styrene butadiene rubber (SBR 1502), the blend was compatibilized with 8 phr of maleated polyethylene (MAPE). To evaluate the curing and mechanical behavior of CMS, it was compared with precipitated silica (reinforcing filler); calcium carbonate and kaolin (non-reinforcing minerals). The addition of CMS reduced the mechanical properties of rubber compound compared to silica rubber/silica composite. The tensile and tear strength values for SBR/CMS were similar to SBR/CaCO₃ and SBR/kaolin. The addition of MAPE to SBR/CMS composite slightly improved the tensile strength, tear strength, abrasion resistance and hardness. In general, CMS performed as diluent filler which reduced the weight of the composite. CMS slightly affected curing speed of SBR/CMS blends. CMS is a waste generated by the use of Clusia multiflora (a timber species endemic of mountains region of Colombia) in the furniture industry. The novelty of this research consists of evaluating the CMS as an alternative to mineral fillers in rubber compounding to improve its mechanical properties, seeking to contribute to the sustainability and to reduce environmental impacts.

杂草木粉对矿物填料作为SBR橡胶复合材料补强材料的对比评估

评价了多瓣clusia木屑（CMS）作为橡胶复合材料的填料。将40 phr的CMS与合成丁苯橡胶（SBR 1502）混合，将共混物与8 phr的马来酸化聚乙烯（MAPE）相容。为了评估CMS的固化和机械性能，将其与沉淀二氧化硅（增强填料）进行了比较。碳酸钙和高岭土（非增强性矿物）。与硅橡胶/二氧化硅复合材料相比，CMS的加入降低了橡胶混合物的机械性能。SBR / CMS的拉伸强度和撕裂强度值与SBR / CaCO ₃相似和SBR /高岭土。在SBR / CMS复合材料中添加MAPE可以稍微改善拉伸强度，撕裂强度，耐磨性和硬度。通常，CMS用作稀释剂填充剂，可减轻复合材料的重量。CMS稍微影响了SBR / CMS混合物的固化速度。CMS是通过在家具行业中使用多花Clusia multiflora（哥伦比亚山区的特有木材物种）而产生的废物。这项研究的新颖性在于评估CMS作为橡胶配混料中矿物填料的替代品，以改善其机械性能，力求对可持续性做出贡献并减少对环境的影响。
