Abstract:
      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.
