| description | In this article, a novel intumescent flame retardant (IFR) PNSFR containing three flame-retardant elements, phosphorus, nitrogen, and sulfur was designed and synthesized. Then a series of flame-retardant thermoplastic polyurethanes (TPU) were prepared using the PNSFR. The effects of the flame retardant on the flammability of TPU/PNSFR composites were investigated by limited oxygen index (LOI) and UL-94 vertical burning. The results showed that TPU containing 10 mass% PNSFR had the highest LOI value (36) and could reach the V-0 rating. The flame-retardant mechanism of PNSFR in TPU was also disclosed using thermogravimetric analysis (TG), scanning electron micrograph, TG-infared spectrometry, and Fourier transform infrared spectroscopy. The sulfur and phosphorus elements of PNSFR can be kept in residual char. Moreover, an optimal loading amount of the IFR in TPU is in favor of forming dense and continuous char layer to prevent heat transfer and the spread of flammable gases. The IFR PNSFR may find potential use for various flame-retardant polyurethanes. |
