摘要

摘要: 详细研究了聚氯乙烯(PVC)、氯化聚乙烯(CPE)和纳米碳酸钙(Nano-CaCO₃)的三元复合体系的加工工艺和组成变化与力学性能之间的关系。研究表明:如果先将CPE等弹性体和纳米CaCO₃制成母粒,然后再与PVC进行混合,有利于纳米粒子在基体中的分散,在复合体系中,纳米CaCO₃和CPE达到了协同增韧PVC的作用,同时,纳米CaCO₃具有补强作用,且当母粒的组成为CPE/纳米CaCO₃=1∶2时,对PVC改性效果最佳。

Abstract: In this paper,the effect of the processing and composition on the mechanical properties of the PVC/elastomer/nano-CaCO₃ ternary-phase composites was investigated in detail.Customarily, CPE or ACR as impact modifier and nano-CaCO₃ was directly added to PVC. However, in this study, the master batch prepared by dispersing the nano-CaCO₃ in CPE, as a novel modifier, was processed with PVC. Improved dispersion of nano-filler in the matrix (observed by SEM ) and good cooperation effect of nano-CaCO₃ and CPE on the toughness were obtained during the processing, as the results showed. Improvement of mechanical properties of the blend system was preferred,when the proportion of CPE to nano-CaCO₃ in the master batch is 1∶2.
