| 中文摘要: |
| 采用橡胶硫化仪研究了溶析成孔工艺制备的硅橡胶泡沫材料的硫化特性，分析讨论了硅橡胶的结构、成孔剂用量对硫化特性的影响规律。研究表明，苯基对硅橡胶的硫化有延迟作用，胶料中成孔剂对硫化有一定影响，成孔剂的刚性和占位作用削弱了胶料的交联，不影响硫化的成孔剂适宜用量为200～230份。 |
| 英文摘要: |
| The vulcanization characteristics of a silicone rubber foam made by technology of removing inert filler used as foaming agent was investigated with curometer.The influence of the silicone rubber structure and inert filler content on the vulcanization characteristics was analyzed.The results showed that the vulcanization was delayed by the phenyl group in the silicone rubber；and the crosslinking was weakened by the rigidity and position occupation of inert filler when more than 230 phr of inert filler was used. |
