| 中文摘要: |
| 采用稀土偶联剂WOT对纳米碳酸钙进行表面改性，通过机械共混法制备纳米碳酸钙/SBR复合材料，研究其性能，并与硅烷偶联剂KH-560进行对比。结果表明，与硅烷偶联剂KH-560相比，稀土偶联剂WOT改性复合材料的加工性能较优，拉伸强度和拉断伸长率较高，稀土偶联剂WOT的最佳用量为1.6份；两种偶联剂均能改善纳米碳酸钙在SBR胶料中的分散性，提高复合材料的动态力学性能。 |
| 英文摘要: |
| The surface of nano-calcium carbonate was modified by rare earth coupling agent WOT，the nano-calcium carbonate/SBR composite was prepared by mechanical blending method，and the properties of the composite were investigated.The results showed that，compared to silane coupling agent KH-560，rare earth coupling agent WOT provided the modified composite better processability，higher tensile strength and elongation at break，the optimal addition level of rare earth coupling agent WOT was 1.6 phr；the dispersion of nano-calcium carbonate in SBR compound was improved by using coupling agent KH-560 and WOT，and the dynamic property of composite was improved. |
