摘要:

聚乳酸是目前最具前景的生物基可降解材料之一,具有诸多优点而被广泛应用于生物医疗与家纺服饰等领域。然而,聚乳酸材料仍存在着易燃烧的不足,限制了其在阻燃要求较高领域的应用与发展,因此聚乳酸阻燃改性迫在眉睫。为更好地掌握聚乳酸阻燃改性现状与发展趋势,本文首先简要介绍了聚乳酸的燃烧过程与阻燃机理,为聚乳酸阻燃改性提供了理论指导。其次,全面综述了聚乳酸阻燃改性的最新进展,包括物理共混、化学共聚与表面修饰等方法,重点阐述了聚乳酸物理共混阻燃改性现状,同时分析总结了不同添加型阻燃剂的优缺点。最后,结合聚乳酸结构特点与阻燃材料发展态势,提出绿色环保、多功能性、高效稳定等阻燃聚乳酸材料将成为未来发展趋势。

Abstract:

Poly(lactic acid) (PLA), one of the most promising bio-based degradable materials, has been widely applied in biomedicine and textile industries due to its superior properties. Unfortunately, the further application of PLA is limited by the defects of easy combustion. Therefore, the flame-retardant PLA (FR-PLA) has drawn much attention from both academia and industrial community. In order to better understand the current situation and development trend of FR-PLA, the combustion process and flame-retardant mechanism of PLA were introduced firstly. Then, the latest progress of flame retardant modification of PLA was comprehensively reviewed, including the physical blending, chemical copolymerization and surface modification. Meanwhile, the present situation of physical blending FR-PLA was emphatically described, and the advantages and disadvantages of different additive flame retardants were also analyzed. In the end, we put forward the future prospect of FR-PLA according to the characteristics of PLA and social development demand. The FR-PLA with multiple functions, environmental protection, high efficiency and stabilization will become future development trend.

Key words: poly(lactic acid), physical blending, chemical copolymerization, surface modification, flame retardant
