| 中文摘要: |
| 以纳米粘土部分等量替代炭黑填充天然橡胶（NR），制备纳米粘土/炭黑/NR复合材料，研究纳米粘土用量对复合材料动态性能的影响。结果表明：当纳米粘土用量较小时，纳米粘土/炭黑/NR复合材料中填料分散性较好；与炭黑/NR复合材料相比，纳米粘土/炭黑/NR复合材料的滞后损失、动刚度和动静刚度比降低，当纳米粘土用量为2份时，复合材料的动态压缩生热和动静刚度比最低。 |
| 英文摘要: |
| The nano-clay/carbon black/NR composites were prepared， and the effects of addition level of nano-clay on the dynamic properties of composites were investigated.The results showed that，while the addition level of nano-clay was low，the filler dispersion of nano-clay/carbon black/NR composites was good. Compared with carbon black/NR composites，the hysteresis loss，dynamic stiffness and spring ratio of nano-clay/carbon black/NR composites were lower.When the addition level of nano-clay was 2 phr，the dynamic compression heat build-up and spring ratio of nano-clay/carbon black/NR composites were the lowest. |
