摘　　要：以AC发泡剂对聚丙烯(PP)/改性纳米CaCO3发泡体系进行挤出发泡,对发泡体系进行单因素轮换法实验,通过观察纵截面泡孔形态,分析各工艺参数对泡孔形态的影响规律,利用正交实验与实验统计软件相结合的方法对实验数据进行回归,得到泡体平均直径、泡孔面积比的预测模型,并进行了实验验证。通过模型预测最佳的加工参数范围,可对实验和实际生产进行指导。PP/modified nano-CaCO3/AC foaming system taking AC as foaming agent is experimented with single factor rotation method to analyze the impact rule of the process parameters on the bubble morphology by observing the shape of bubble morphology on the longitudinal. The experimental data is regressed with orthogonal experiment method and statistical software to acquire the model of average diameter and the cell area ratio, and the result is validated by experiment. The model can predict the best range of process parameters, and it can be a guidance for the experiments and the actual production.
