如何同时提高PET等高分子材料的阻燃性和耐熔滴性是一个很大的挑战。本文以TPA、EG、DDP和O-MMT为原料，通过缩聚反应合成了一种新型的膨胀型阻燃剂DPSPB，并将其与PET/DDP/O-MMT纳米复合材料共混。所得PET-co-DDP/O-MMT/DPSPB纳米复合材料表现出非常好的阻燃性和抗滴落性，例如，LOI = 29，UL-94 V-0。采用SEM、XRD、XPS等测试手段研究了复合材料的结构与性能之间的关系。结果表明，DPSPB对纳米复合材料的结构起到了很好的保护作用，使纳米复合材料具有良好的抗滴落性能。
It is a big challenge to improve simultaneously both the flame retardancy and the melt-dripping resistance of polymeric materials such as PET. In this paper, a novel intumescent flame retardant, DPSPB, was synthesized and blended with copolyester PET-co-DDP/O-MMT nanocomposites, which were synthesized by polycondensation of TPA, EG, DDP, and O-MMT. The resulting PET-co-DDP/O-MMT/DPSPB nanocomposites exhibit very good flame retardance and dripping resistance, e.g., LOI = 29, UL-94 V-0. SEM, XRD, and XPS were used to investigate the relationships between the structures and properties of the composites. It is proved that DPSPB offers excellent protection for the structure of nanocomposites, which is responsible for the good anti-dripping properties of the nanocomposites.
