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1.5-2h，氯气流量554mL·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。

Abstract：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 1.5-2h, 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 aggregated structure of the chlorinated carbon black changed, but the chain structure didn't.
Keywords：chlorinated carbon black; modification; structure
