Abstract

This study deals with the synthesis and evaluation of salen based derivatives as fire retardants in thermoplastic polyurethane. Salens, hydroxysalens and their first row transition metal complexes (salen-M) were synthesized (Copper, Manganese, Nickel and Zinc). They were then incorporated in thermoplastic polyurethane (TPU) with a loading as low as 10:1 weight ratio. The thermal stability as well as the fire properties of the formulations were evaluated. Thermogravimetric analysis (TGA) showed that different coordination metals on the salen could induce different decomposition pathways when mixed with TPU. The Pyrolysis Combustion Flow Calorimetry (PCFC) results showed that some M-salen have the ability to significantly decrease the peak heat release rate (-61% compared to neat TPU) and total heat released (-63% compared to neat TPU) when formulated at 10:1 wt % ratio in TPU. Mass Loss Cone Calorimetry (MLC) results have shown that some additives (salen-Cu and salen-Mn) exhibit very promising performance and they are good candidates as flame-retardants for TPU.

摘要

本研究涉及基于水杨醛衍生物作为热塑性聚氨酯阻燃剂的合成与评价。合成了水杨醛、羟基水杨醛及其第一行过渡金属配合物（salen-M）（铜、锰、镍和锌）。然后将它们以低至10:1的重量比掺入热塑性聚氨酯（TPU）中。对配方的热稳定性和燃烧性能进行了评价。热重分析（TGA）表明，水杨醛上不同的配位金属与TPU混合时可诱导不同的分解途径。热解燃烧流动量热法（PCFC）结果表明，当以10:1的重量比在TPU中配制时，一些M-salen能够显著降低峰值热释放速率（与纯TPU相比降低61%）和总热释放量（与纯TPU相比降低63%）。质量损失锥形量热法（MLC）结果表明，一些添加剂（salen-Cu和salen-Mn）表现出非常有前景的性能，它们是TPU阻燃剂的良好候选物。
