In an attempt to investigate the synergies between aluminum diethylphosphinate (AlPi) and phosphonate-based phosphorus–nitrogen (P–N) flame retardants (FRs) in glass fiber-reinforced poly(butylene terephthalate) (GF-PBT), novel piperazine analogue-based P–N FRs were synthesized. The thermal degradation and flame-retarding performance when cooperating with a commercial AlPi product, Exolit OP 1240, were determined, and their synergistic results were compared with a well-known melamine polyphosphate (MPP) synergist. As a result of TGA, SEM, and FTIR analyses, it was found that the phosphonate-based P–N FRs yielded improved synergism even with a lower P % content loading compared to MPP. To achieve a V-0 rating, the P content loading of piperazine analogue-based P–N FRs was 0.43% in the GF-PBT/OP1240 mixture at a 13.3 phr loading while that of MPP should be higher than 0.53% in the same formulation. The P content is the governing factor in the fire-retarding efficiency of phosphonate-based P–N FRs, which was well correlated with OP1240 in the gas phase. It is demonstrated that the combination of piperazine analogue-based P–N FRs with OP1240 significantly improves both thermal stability and flame retardancy of GF-PBT material.

新型膦酸盐基磷氮阻燃剂及其在与 OP1240 一起应用于玻璃纤维增​​强聚(对苯二甲酸丁二醇酯)中时作为增效剂的用途

为了研究二乙基次膦酸铝 (AlPi) 和基于膦酸盐的磷氮 (P-N) 阻燃剂 (FRs) 在玻璃纤维增​​强聚对苯二甲酸丁二醇酯 (GF-PBT) 中的协同作用,新型哌嗪类似物 -合成了基于 P-N 的 FR。确定了与商业 AlPi 产品 Exolit OP 1240 合作时的热降解和阻燃性能,并将它们的协同结果与众所周知的三聚氰胺多磷酸盐 (MPP) 增效剂进行了比较。TGA、SEM 和 FTIR 分析的结果发现,与 MPP 相比,即使在 P% 含量较低的情况下,基于膦酸盐的 P-N FR 也能产生更好的协同作用。为了达到 V-0 等级,基于哌嗪类似物的 P-N FRs 在 GF-PBT/OP1240 混合物中的 P 含量负载为 0.43%,为 13。3 phr 的装载量,而 MPP 的装载量在相同配方中应高于 0.53%。P 含量是影响基于膦酸盐的 P-N FRs 阻燃效率的控制因素,这与气相中的 OP1240 有很好的相关性。结果表明,基于哌嗪类似物的 P-N FRs 与 OP1240 的组合显着提高了 GF-PBT 材料的热稳定性和阻燃性。
