| 摘 要： | 分别制备了以炭黑和白炭黑为补强填料的不同硫化体系天然橡胶(NR)复合材料,研究硫化体系对NR胶料静态和动态性能的影响。结果表明:普通硫化体系硫化胶具有较高的交联密度、较好的物理性能和优异的耐磨性能;对于白炭黑补强体系,普通硫化体系硫化胶具有最低的滚动阻力;而对于炭黑补强体系,平衡硫化体系硫化胶具有最低的滚动阻力;胶料拉伸强度的增大有利于耐磨性的提高。

| Abstract: | Carbon black and silica filled NR with different curing systems were prepared. The relationship between static and dynamic properties, and cross-linking structure resulting from different curing systems was studied. Also, the influence of different filler types on the above relationship was investigated. The result showed that NR composites with CV system had higher crosslinking density and better performance on tensile strength and abrasion resistance, compared with other curing systems. For the dynamic properties, the silica-reinforced NR with CV system had lower rolling resistance and better abrasion resistance. For CB-reinforced NR with EC system had lower rolling resistance. The improvement of tensile strength is beneficial to the abrasion resistance. |
