| 中文摘要: |
| 研究了硫化剂DL-268对NR/SBR胶料各项性能的影响。试验结果表明,在NR/SBR胶料中加入2份硫化剂DL-268,可改进抗硫化返原性,提高硫化胶在热氧老化或过硫化状态下的物理性能及胶-帘线之间的粘合力, 降低硫化胶的疲劳温升。所得结果与所选择的试验配方构成有关。 |
| 英文摘要: |
| The effect of the curing agent DL-268 on the properties of NR/SBR compound was investigated.The results showed that the reversion resistance , the physical properties of thermal-oxidative aged vulcanizate or overcured vulcanizate,and the adhesion strength between rubber and cord were improved by adding 2 phr of DL-268 to NR/SBR compound ;and the fatigue heat build-up of vulcanizate decreased .The results were related to the composition of selected formula. |
