%X 采用偶联剂Si69对棒状秸秆纳米纤维素（SNC）进行改性，得到改性棒状秸秆纳米纤维素（MSNC），研究MSNC对炭黑（CB）补强天然橡胶（NR）性能的影响。结果表明：MSNC与橡胶基体的相容性较好；与CB/SNC/NR复合材料相比，CB/MSNC/NR复合材料的交联密度较大，能在保持较好抗湿滑性能的同时降低滚动阻力，具有更强的交联网络和更多的受限橡胶分子，热稳定性更好；用量比为100/35/10的CB/MSNC/NR复合材料物理性能最佳。;The rod-shaped straw nanocellulose（SNC） was grafted by coupling agent Si69 to obtain modified rod-shaped straw nanocellulose（MSNC）.The effect of MSNC on the properties of carbon black（CB） reinforced natural rubber（NR） was studied.The results showed that，MSNC had better compatibility with rubber matrix.Compared with CB/SNC/NR composite，CB/MSNC/NR composites had greater crosslink density，better wet skid resistance and lower rolling resistance，stronger cross-linking network，more restricted rubber molecules and better thermal stability.CB/MSNC/NR composite with a ratio of 100/35/10 had the best physical properties
