炭黑（CB）和二氧化硅作为增强填料，增加了橡胶的使用性能。由于每种填料都具有各自的优点，因此使用二氧化硅/炭黑共混物可以提高天然橡胶（NR）硫化胶的力学和动态性能。然而，产生最佳性能的最佳二氧化硅/炭黑比需要澄清。本文研究了不同配比的二氧化硅/炭黑复合填料对NR的补强，以确定最佳的二氧化硅/炭黑比。杂化填料总含量为50 phr。测定了NR硫化胶的抗拉强度、撕裂强度、耐磨性、抗裂纹扩展性、耐热性和抗滚压性等力学性能。结果表明：含硅量为20和30份的硫化胶整体力学性能较好；(C) 2007 Elsevier Ltd.版权所有。
Carbon black (CB) and silica have been used as the main reinforcing fillers that increase the usefulness of rubbers. As each filler possesses its own advantages, the use of silica/CB blends should enhance the mechanical and dynamic properties of natural rubber (NR) vulcanizates. However, the optimum silica/CB ratio giving rise to the optimum properties needs to be clarified. In this research, reinforcement of NR with silica/CB hybrid filler at various ratios was studied in order to determine the optimum silica/CB ratio. The total hybrid filler content was 50 phr. The mechanical properties indicating the reinforcement of NR vulcanizates, such as tensile strength, tear strength, abrasion resistance, crack growth resistance, heat buildup resistance and rolling resistance, were determined. The results reveal that the vulcanizates containing 20 and 30 phr of silica in hybrid filler exhibit the better overall mechanical properties. (C) 2007 Elsevier Ltd. All rights reserved.
