摘要：An intumescent flame retardant (IFR) system was created using a benzene-rich triazinebased hyperbranched charring agent (CDS) and aluminum diethlyphosphinate (AlPi) to enhance the flame resistance of thermoplastic polyester elastomers (TPEE). Thermogravimetric analysis (TGA) results revealed that CDS had substantial char residue (50.8 wt%) and good thermal stability at 700 degrees C. The limiting oxygen index (LOI) value achieved 30.2% and it passed the V-0 rating in vertical combustion (UL-94) with the integration of 20 wt% (wt%) IFR (AlPi:CDS = 3:1) into TPEE matrix. Scanning electron microscope (SEM), laser Raman spectroscopy (LRS), and heating infrared spectroscopy were used to examine the morphology and chemical makeup of char residues, as well as the evolution of the structure during the heating process. The outcomes demonstrated the compatibility of CDS and AlPi in both the gas phase and the condensed phase. After burning, the high-efficiency flame-retardant TPEE composite created a dense, continuous char layer that contained triazine rings and aromatic ring structures.(c) 2023 The Author(s).
