中文摘要: |
采用两种不同工艺制备甲基乙烯基硅橡胶(MVQ)/丙烯酸酯橡胶(ACM)并用胶,研究制备工艺对MVQ/ACM并用胶结构和物理性能的影响。结果表明:与分别制备MVQ/白炭黑和ACM/白炭黑混炼胶工艺相比,MVQ/白炭黑混炼胶直接与ACM共混制备的并用胶分散较为均匀,并对一段硫化诱导期具有延迟作用。该工艺制备的混炼胶在一段硫化条件为160 ℃×12 min、二段硫化条件为180 ℃×120 min时制得的并用胶的综合性能较好。 |

The effects of preparation process on the properties of MVQ/ACM blend were investigated.The results showed that,compared with the preparation process in which ACM/silica and MVQ/silica were mixed separately,by mixing ACM with MVQ/silica compound directly,the dispersion of ACM in the MVQ/ACM blend was better and the first stage vulcanization induction time was extended.The optimum vulcanization condition was 160 ℃ for 12 min firstly and then 180 ℃ for 120 min. |
