摘要
本文是一篇关于非弹性增韧方法的综述。文章首先简要回顾了传统的橡胶增韧韧性聚合物材料的机理,然后着重介绍了最近在国外出现的刚性有机填料(ROF)增韧的基本概念、分析方法和增韧的冷拉机理,列举了脆性塑料粒子和韧性基体组成的合金体系的大量实验结果来说明以上内容,最后通过与传统橡胶增韧机理的对比指出非弹性体增韧是不同于后者的一种新增韧方法,并有可能成为制备高强度、高韧性工程塑料的一种新途径。
This is a review on polymer toughening by non-elastomer. The toughening mechanisms of rubber-modified plastics are reviewed first. Then the concept of Rigid Organic Filler (ROF) and Cold-drawing, and methods of analysing the toughened system are introduced, and experiments in polymer blends consisting of brittle polymer particles dispersed in ductile polymers are cited to explain them. By comparision with the toughening mechanisms of rubber-modified plastics, it is concluded that toughening by such non-elastomer is a new mechanism and is a potential new route to toughened plastics.
