摘　　要：采用物理球磨法和复配偶联剂化学接枝法相结合对粉煤灰进行改性,研究改性粉煤灰对氯丁橡胶(CR)性能的影响。结果表明:改性粉煤灰平均粒径减小至5.79μm,复配偶联剂在粉煤灰表面形成完整包覆层,使其疏水性增强,Zeta电位绝对值减小,达到良好的表面改性效果;在CR中填充10～20份改性粉煤灰,其可与炭黑具有良好的协同作用,硫化胶综合性能最优。The fly ash was modified by physical ball milling and chemical grafting of complex coupling agent,and the effect of the modified fly ash on the properties of chloroprene rubber(CR) was studied. The results showed that the average particle size of the modified fly ash was reduced to 5. 79 μm,and the complex coupling agent formed a complete coating on the surface of the fly ash. The hydrophobicity of the fly ash was enhanced and the absolute value of the Zeta potential was reduced,indicating achievement of good surface modification. With 10~20 phr of modified fly ash with carbon black,a good synergistic effect was obtained, and the compound had optimal comprehensive properties.
