摘　　要：通过SEM观察了活化改性粉煤灰在硬质PVC发泡板材中的分布,考察了其对硬质PVC发泡板材加工性能和力学性能的影响。结果表明:活化改性粉煤灰在硬质PVC发泡板材中分布均匀,起到了填充增强作用,可替代硬质PVC发泡板材中的碳酸钙,从而降低成本。The distribution of activation modified fly ash in rigid PVC foamed board was observed by SEM.The effects of the fly ash on the processing property and mechanical properties of rigid PVC foamed board was investigated.The results showed that the activation modified fly ash dispersed evenly in the rigid PVC foamed board,played a filling and strengthening role,and could replace calcium carbonate in the rigid PVC foam board,thus reducing the cost.
