| 中文摘要: |
| 采用气-固相搅拌式氯化法对炭黑进行氯化改性，并利用二元回归分析法研究了氯化炭黑中氯质量分数与反应温度、时间和氯气流量的关系。结果表明，氯化反应条件为:温度 130 ℃，时间 1.5～2 h，氯气流量 554 mL·min-1时反应效果较好；氯化炭黑后处理的方法可采用充氮气法替代水洗处理法；扫描电镜照片表明，氯化后的炭黑，其聚集结构有所变化，但链状结构没有被破坏。 |
| 英文摘要: |
| The carbon black was modified by gas-solid stirring chlorination，and the chlorine content in the chlorinated carbon black as a function of the temperature and time of reaction，and the chlorine flow was investigated with the binary regressive analysis.The results showed that the suitable reaction conditions were as follows:temperature 130 ℃，time 1.5～2 h，chlorine flow 554
mL·min-1；the nitrogen-filled treatment could be used instead of the water flushing treatment for the post-treatment of chlorinated carbon black；it was indicated by SEM that the agg regated structure of the chlorinated carbon black changed，but the chain structure didnt. |
