| 中文摘要: |
| 采用机械共混法制备有机蒙脱土（OMMT）/氯丁橡胶（CR）纳米复合材料，对复合材料的结构、性能及在输送带中的应用进行研究。结果表明：采用机械共混法能够制备分散均匀的半剥离型OMMT/CR纳米复合材料；OMMT对CR具有良好的补强作用，当OMMT用量仅为3份时，复合材料的拉伸强度和撕裂强度显著提高，耐热空气老化性能改善；在输送带覆盖胶中采用OMMT部分替代炭黑，覆盖胶的拉伸强度和撕裂强度略有增大，耐磨性能显著提高。 |

| The OMMT/CR nanocomposite was prepared by mechanical blending method，and its structure，properties and application in conveyor belt were investigated.It was found that the half-exfoliated OMMT/CR nanocomposite with uniform dispersion of OMMT was prepared.The reinforcement of OMMT to CR was good，the tensile strength and tear strength of OMMT/CR nanocomposite increased significantly by only using 3 phr OMMT，and the thermal aging property improved.By using OMMT to partially replace carbon black in the cover compound of conveyor belt，the tensile strength and tear strength of compound increased slightly，and the wear resistance increased significantly. |
