添加增塑剂可改善聚氯乙烯(PVC)薄膜性能,近年来研究发现,通用型PVC增塑剂邻苯二甲酸酯具有潜在的致癌性,威胁人类的健康,对环保性增塑剂的研发是近年来的热点。本文主要阐述增塑剂的増塑机理、PVC环保增塑剂的应用原理,进而对几种新型环保增塑剂的増塑效果和制备方法进行介绍。
Adding plasticizers can improve the properties of polyvinyl chloride (PVC) film. In recent years, it has been found that common PVC plasticizers, phthalates, are potentially carcinogenic and pose a threat to human health. R & D is a hot spot in recent years. This article mainly expounds the plasticizing agent’s plasticizing mechanism and the application principle of PVC green plasticizer, and then introduces the plasticizing effect and preparation methods of several new green plasticizers.
