| 中文摘要: |
| 在改性气相法白炭黑填充NR胶料中加入粘合剂RH，研究粘合剂RH用量对胶料性能的影响，并与偶联剂Si69/气相法白炭黑胶料进行对比。结果表明，粘合剂RH的加入明显改善了硫化胶的物理性能，拉伸强度提高10%以上；粘合剂RH用量为4份时，硫化胶的综合物理性能最佳；有机改性剂M2改性气相法白炭黑参与了橡胶的共硫化，使硫化胶的交联密度增大；偶联剂Si69对硫化胶物理性能的改善效果不及粘合剂RH。 |
| 英文摘要: |
| The effect of the additional level of adhesive RH on the properties of NR/modified fumed silica compounds was investigated and these properties were compared to those of NR/Si69/silica compound.The results showed that the physical properties of vulcanizate improved significantly by adding adhesive RH，e.g. the tensile strength increased by above 10%；the vulcanizate with the best comprehensive physical properties was obtained by adding 4 phr adhesive RH；the fumed silica modified by the organic modifier M2 participated the covulcanization with NR to increase the crosslink density of vulcanizate；and the coupling agent Si69 was poorer than the adhesive RH for improving the physical properties of vulcanizate. |
