摘　　要：采用光电子能谱、元素分析、红外光谱、裂解-气/质联用仪和扫描电镜等表征塑料用C364色素炭黑的结构,并用哈克转矩流变仪、老化试验箱等研究C364色素炭黑与聚乙烯(PE)、聚氯乙烯(PVC)、聚丙烯腈-丁二烯-苯乙烯(ABS)等树脂复配后的加工性能、制品的力学性能和抗老化性能。结果表明:以炉法炭黑为基料通过沸腾床氧化器和旋转氧化器的两步臭氧氧化后,增加了产品炭黑粒子表面的羟基、羧基、羰基等官能团,提高了相应的性能。C364色素炭黑应用于PE、PVC、ABS等树脂中,其加工性能良好,制品的力学性能符合要求,能使PE的老化寿命延长10倍以上。Three samples, C364 carbon black, C364 carbon black pigment after a two step ozone oxidation, and MA100 from Mitsubishi Corporation, were characterized by XPS, IR, SEM, PY-GC/MS spectroscopy and elemental analysis. The processing parameters, mechanical properties, aging resistance and micro-morphology of the oxidized C364 carbon black pigment and its composites with polyethylene, polyvinyl chloride and poly （acry- lonitrile-butadiene-styrene） resins were characterized by a HAAKE torque rheometer, scanning electron micros- copy and an aging test chamber. Results show that oxidized C364 carbon black pigment contains more hydroxyl, carbonyl, carboxyl and other functional groups than the original C364 sample. The mechanical properties of the composites with oxidized C364 carbon black pigment were almost the same as those of MA100-based ones. Oxi- dation of the C364 carbon black pigment significantly increased the photo aging lifetime of the polyethylene- based composite 10 times.
