| 中文摘要: |
| 对炭黑和白炭黑分别填充的天然橡胶（NR）胶料进行电子辐射预硫化，研究辐射预硫化对胶料的结合胶含量、门尼粘度和硫化特性及硫化胶的物理性能和动态性能的影响。结果表明，辐射预硫化能提高胶料的结合胶含量、门尼粘度和硫化速度，对两种硫化胶的应力应变、生热和磨耗等性能产生不同的影响，并能显著抑制填料在橡胶基体内网络结构的形成，降低胶料的滞后损失。 |
| 英文摘要: |
| Natural rubber filled with carbon black or silica was precured by electron beam，and the effect of irradiation precuring on the bound rubber content，Mooney viscosity and curing characteristics of the compound，and effect on the mechanical properties and dynamic properties of the vulcanizates were investigated.The results showed that，irradiation precuring increased the bound rubber content，Mooney viscosity and curing speed，but it had different effects on the stress-strain properties，heat build-up and abrasion resistance of these two vulcanizates filled with carbon black or silica，respectively，and irradiation precuring could effectively restrain the formation of filler network in the rubber matrix which resulted in a reduced hysteresis loss. |
