摘　　要：将不同用量的成核剂TiO2添加到聚烯烃发泡母粒中,通过对各样品的力学性能、发泡倍率、泡孔结构的测试与观察,发现当成核剂TiO2用量为7.5份时,聚烯烃发泡材料的力学性能最好,密度最低,材料内部泡孔大小均一,且分布均匀。Different contents of nucleate agent TiO2 were added to PO foaming master batch. The specimens＇ mechanical properties, expansion ratio and foam morphologies were tested and investigated. The results showed the mechanical properties of the foamed material were the best, the density was the lowest, the cell size was homogeneous and distributed homogeneously when the content of the nucleate agent TiO2 was 7.5 phr.
