摘　　要：探讨了纳米级ＣａＣＯ３ 粒子增韧增强ＰＶＣ／ＣＰＥ 基理，研究了纳米级ＣａＣＯ３ 与轻质ＣａＣＯ３ 用量对ＰＶＣ／ＣＰＥ 体系力学性能的影响。结果表明：纳米级ＣａＣＯ３ 用量为５ ％ ～１２ ％ 时体系拉伸强度，冲击强度都有明显提高，起到了增韧、增强的双重效果。轻质ＣａＣＯ３ 填充ＰＶＣ／ＣＰＥ 体系基本未见增韧效果，同时，随着轻质ＣａＣＯ３ 用量的增加，体系的拉伸强度和断裂伸长率明显降低。s In this paper the toughening mechanism of PVC/CPE filled with Nano CaCO 3 and the effects of nano CaCO 3and light CaCO 3contents on properties of PVC/CPE were studied. The results showed PVC/CPE/CaCO 3had excellent notched impact strength and tensile strength when nano CaCO 3content was 5%～12%. Light CaCO 3had no obvious toughening effect on PVC/CPE, but made the tensile strength and elongation at break of PVC/CPE decreased greatly.
