Abstract

Long-chain bio-based polyamide has shown promising development prospects due to its excellent properties and green renewable characteristics; however, synthesizing inherently flame-retardant long-chain bio-based polyamide remains a big challenge due to the lack of effective knowledge of the key polymerization process. Herein, intrinsicly flame-retardant long-chain bio-based polyamide 512 (PA512) was synthesized in the presence of a reactive flame retardant with high thermal stability and good water solubility. The reaction conditions and existing problems in each stage of the copolymerization system have been clarified and optimized. By utilizing a two-step pre-polymerization approach, a series of intrinsicly flame-retardant PA512 (FRPA512) with large molecular weight, high phosphorus element content and good mechanical properties were obtained. More importantly, the prepared FRPA512 with 5wt% flame retardant loading exhibited good flame retardancy, showing a limiting oxygen index (LOI) of 28.1% and a vertical burning rating of V-0. This study provides a feasible solution to the common problem in the synthesis of flame-retardant polyamides, while also offering new insights for future modification of polyamide copolymerization.

合成高性能固有阻燃长链生物基聚酰胺的关键工艺控制。
长链生物基聚酰胺以其优异的性能和绿色可再生的特点展现了广阔的发展前景,然而,由于缺乏对关键聚合过程的有效了解,合成固有阻燃长链生物基聚酰胺仍然是一个巨大的挑战。本文在反应型阻燃剂的存在下合成了本征阻燃长链生物基聚酰胺 512(PA512),该聚酰胺具有高热稳定性和良好的水溶性。明确并优化了共聚体系各阶段的反应条件和存在的问题。通过采用两步预聚合方法,获得了一系列分子量大、磷元素含量高、机械性能好的本征阻燃 PA512(FRPA512)。更重要的是,所制备的阻燃剂含量为 5wt% 的 FRPA512 具有良好的阻燃性,其极限氧指数(LOI)为 28.1%,垂直燃烧等级为 V-0。该研究为阻燃聚酰胺合成中的常见问题提供了可行的解决方案,同时也为今后聚酰胺共聚改性提供了新的思路。
