摘要

鉴于环保的压力，无卤阻燃剂逐渐替代含卤阻燃剂，用在聚乙烯醇(Polyvinyl alcohol，PVA)阻燃处理中。本文综述了近年来无卤阻燃PVA的最新研究进展，总结分析了无机型阻燃剂、磷系阻燃剂、氮系阻燃剂、膨胀型阻燃剂及反应型阻燃剂对PVA的阻燃研究现状，介绍了不同类型阻燃剂的阻燃机理、优缺点以及典型阻燃剂对PVA阻燃性质和力学性质的影响；在此基础上讨论了 PVA阻燃的独特性，充分利用PVA的结构特征，研制出适合PVA加工方式的阻燃剂复配配方是PVA阻燃研究的主要发展方向。

Abstract

Halogen-free flame retardants are introduced into PVA to replace the conventional halogen-contained flame retardant owning to the increasing environmental pressure. The current research progress and development trend of halogen-free flame retardant for Polyvinyl alcohol (PVA) were reviewed. The studies of various kinds of PVA flame retardants containing inorganic flame retardant

phosphorus/nitrogen contained flame retardant

intumescent flame retardant and reactive flame retardant were summarized and analyzed. The flame retarding mechanism

the advantages and disadvantages of different PVA flame retardant

and the influence of typical flame retardant on properties of PVA were introduced. On this basis

the uniqueness of PVA flame retardant was discussed. The trend of PVA flame retardant research is to develop a compound formula suitable for PVA processing considering the structural features of PVA.
