| 中文摘要: |
| 对采用溶析成孔技术发泡的甲基苯基乙烯基硅橡胶胶料的硫化特性影响因素进行了探讨。结果表明，活性剂（氧化锌晶须和N，N’-间亚苯基双马来酰亚胺）能缩短发泡胶料的高温正硫化时间，但对发泡胶料的低温硫化促进作用不明显；发泡胶料在室温存放过程中有缓慢硫化的趋势，室温短时间（5 d内）存放不会影响发泡胶料的最终硫化效果；球形成孔剂表面滞留的处理剂会对发泡胶料的硫化产生负作用。 |
| 英文摘要: |
| The effective factors on the curing characteristics of silicone rubber（MPVQ）foam prepared with the technology of removing temporary filler were investigated.The results showed that the activators[zinc oxide whisker and N，N’-m-phenylene bismaleimide（HVA-2）]could reduce the optimum cure time of MPVQ foam at high temperature，but had little effect of accelerating cure of MPVQ foam at low temperature；the MPVQ foam tended to be cured slowly during the storage at room temperature and the up to 5 days storage at room temperature didn’t have adverse effect on the final cure state of MPVQ foam，but the residual treating agent on spherical blowing agent did. |
