改性聚氯乙烯及其研究进展

Research Development of Modified Polyvinyl Chloride

聚氯乙烯具有不燃性、耐化学稳定性好和电绝缘性能优良等特点,广泛地应用于建筑材料、工业制品、日用品、地板革、地板砖、人造革、管材和电线电缆等领域。但聚氯乙烯也存在耐老化性差和力学性能较差等问题,严重限制了它在工程领域的广泛应用。为了解决这些存在的不足,有必要对聚氯乙烯进行各种改性以研制出高性能和多用途的聚氯乙烯产品。本文主要介绍了聚氯乙烯的常用改性方法及其性能特点,重点总结了改性聚氯乙烯产品的应用领域,最后提出了聚氯乙烯的环境问题及回收应用。

Polyvinyl chloride (PVC) is widely used in building materials, industrial products, daily necessities, floor leather, floor tiles, artificial leather, pipes, wires and cables and other fields due to its incom-bustibility, good chemical resistance and electrical insulation. However, PVC also has poor aging resistance and mechanical properties, which seriously limits its wide application in the engineering fields. In order to solve these problems, it is necessary to modify PVC to develop high- performance and versatile PVC products. This paper mainly introduces the commonly used modification meth-ods of PVC and their performance characteristics, especially in detail summarizes the application fields of modified PVC products, and finally puts forward the environmental problems and recy-cling applications of PVC.
