| 中文摘要: |
| 研究硫黄、促进剂NS和硫化剂DTDM用量对天然橡胶（NR）胶料性能的影响。在半有效硫化体系中，当硫黄用量为1.8～2份，促进剂NS用量为1.4～1.6份，硫化剂DTDM用量为0.6～0.8份时，NR硫化胶具有较好的物理性能和耐磨性能。利用正交试验法，确定硫黄、促进剂NS和硫化剂DTDM及其交互作用对NR胶料耐磨性能的影响，并通过直观分析和方差分析确定NR胶料DIN磨耗量最小的半有效硫化体系的配方为：硫黄 1.8，硫化剂DTDM 0.8，促进剂NS 1.4。 |

| The effects of the addition level of sulfur，accelerator NS and curing agent DTDM on the properties of NR compound were investigated.The results showed that，for semi-efficient vulcanization system，when the addition level of sulfur，accelerator NS and curing agent DTDM was 1.8～2，1.4～1.6 and 0.6～0.8 phr respectively，the NR vulcanizate had better physical properties and wear resistance.By using the orthogonal experimental design，the effects of sulfur，accelerator NS，curing agent DTDM and their interaction on the wear resistance of NR compound were analyzed. Based on the test results and variance analysis，the optimum formulation of semi-efficient vulcanization system with minimum DIN abrasion loss was obtained as follows：sulfur 1.8 phr，curing agent DTDM 0.8 phr，and accelerator NS 1.4 phr. |
