| 中文摘要: |
| 研究普通硫化体系和半有效硫化体系对天然橡胶（NR）各项性能的影响。结果表明：与普通硫化体系NR胶料相比，半有效硫化体系NR胶料的硫化返原程度小，物理性能、压缩疲劳性能、耐磨性能和耐热老化性能好，且随着促进剂用量的增大性能更优，但耐切割性能变差；随着硫化时间的延长，普通硫化体系和半有效硫化体系NR胶料的压缩疲劳温升和磨耗量均增大，且普通硫化体系胶料增幅更大。 |
| 英文摘要: |
| The properties of natural rubber（NR）compounds with conventional vulcanization system (CV) and semi-efficient vulcanization system (SEV) were investigated.The results showed that，compared with NR compound with CV，NR compound with SEV had less cure reversion，better physical properties，compression fatigue property，wear resistance and thermal aging property.In addition，those properties of the NR compound with SEV were improved as the addition level of accelerator increased. However，the cut resistance of NR compound with SEV was inferior to that of NR compound with CV.As the curing time extended，the compression fatigue temperature rise and abrasion loss of NR compounds with both CV and SEV increased，and those of NR compound with CV increased more significantly. |
