| Abstract: |
| The fly ash was modified by physical ball milling and chemical grafting of complex coupling agent，and its effect on 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，to achieve a good surface modification effect.Filling 10～20 phr of modified fly ash with carbon black forming a good synergistic effect，the compound had optimal comprehensive properties. |
