中文摘要: |
利用氨离解物理吸附键的方法,研究了炭黑、白炭黑/偶联剂及炭黑/偶联剂/白炭黑与NR/BR的相互作用及其对硫化胶性能的影响。结果表明:橡胶-炭黑相互作用中共价键占40%,物理作用占优势,橡胶-偶联剂-白炭黑相互作用中共价键占66%;橡胶-偶联剂-白炭黑-炭黑相互作用中共价键占71%~73%,大于白炭黑或炭黑单用的情况。 |
英文摘要: |
The interaction between carbon black, silica/coupling agent or carbon black/coupling agent/silica and NR/BR and its influence on the properties of vulcanizate were investigated by NH3 absorpt ionmethod .The results showed that the covalent bonds accounted for 40%in the rubber-black bonds,while the physical bonds were predominant;the covalent bonds accounted for 66% in rubber-coupling agent-silica bonds;and the covalent bonds accounted for 71%~73%in rubber-coupling agent-silica-black bonds. |
