| 摘 要： | 采用熔融共混法制备玻纤增强聚对苯二甲酸乙二酯/微胶囊红磷/有机改性蒙脱土（GF-PET/MRP/OMT）复合体系，并对材料的热稳定性和阻燃性进行了研究.当向GF-PET/MRP中引入OMT时，材料的残炭含量显著提高；与GF-PET/MRP相比，OMT的加入虽然使材料的LOI有所下降，但锥型量热结果表明，OMT不仅使材料的点燃时间滞后，而且热释放速率峰值也得到了下降.此外，GF-PET/MRP阻燃材料燃烧后形成较为平整的炭层结构，而GF-PET/MRP/OMT其残炭呈现褶皱形貌.该褶皱状结构的炭层能够更有效地起到隔氧隔热的作用，从而提高材料的热稳定性及阻燃性能.

| Abstract: | Effects of organo-montmorillonite （OMT） on the flame retardancy and thermal stability of microencapsu- lated red phosphorus （MRP） flame retarded glass fiber reinforced PET （GF-PET） were investigated. Incorporating OMT into GF-PET/MRP, the nanocomposites showed higher char residues than GF-PET/MRP materials. Com- pared to GF-PET/MRP, the addition of OMT can not only delay the time to ignition （TTI）, but further reduce the peak heat release rate （PHRR） of samples. The char residue of GF-PET/MRP displayed a plain land-like structure, while the residue of GF-PET/MRP/OMT displayed a folded structure morphology because of the deposition of car- bonaceous residues on the surface of montmorillonite layers. This folded morphology of residue was responsible for the enhanced thermal stability and improved flame retardancy. |
