| 中文摘要: |
| 采用超声粉碎法制备二硫化钼（MoS2）纳米碎片，以不同用量的MoS2（纳米碎片）等量替代天然橡胶（NR）/炭黑（CB）复合材料中部分CB，制得NR/CB/MoS2复合材料，研究不同用量MoS2等量替代部分CB对复合材料Payne效应、硫化特性、物理性能、耐磨性能和动态力学性能的影响。结果表明：少量MoS2等量代替部分CB有助于复合材料中填料分散，MoS2用量过大则使填料又趋于聚集；少量MoS2等量代替部分CB会减弱复合材料的Payne效应，有利于提高复合材料的物理性能和耐磨性能，但对复合材料的滚动阻力和抗湿滑性能影响较小；过量MoS2等量代替部分CB，则其对复合材料的补强能力减弱，甚至导致复合材料性能下降。 |
| 英文摘要: |
| Molybdenum disulfide（MoS2） nanoparticles were obtained by ultrasonic method，and the natural rubber（NR）/carbon black（CB）/MoS2 composites were prepared by using MoS2 nanoparticles to replace equal amount of CB in the NR/CB composites. The influence of MoS2 on the Panye effect，vulcanization characteristics，physical properties，wear resistance and dynamic mechanical properties of the composites was investigated. The results showed that adding a small amount of MoS2 could improve the filler dispersion. However，when the amount of MoS2 increased，the fillers tended to aggregate again. Payne effect of the composites was weakened by using a small amount of MoS2，the physical properties and wear resistance were enhanced，and the rolling resistance and wet-slip resistance of the composites were only slightly affected. When the amount of MoS2 increased to a large number，the reinforcement was weakened，and the performance of the composites deteriorated. |
