Abstract

This article mainly studies the flame retardant and thermal degradation properties of thermoplastic polyurethane (TPU) composites based on HGM@[EOOEMIm][BF4], prepared by modifying hollow glass microsphere (HGM) with ionic liquid [EOOEMIm][BF4]. The physical and chemical characteristic of HGM@[EOOEMIm][BF4] was tested by X-ray photoelectron spectroscopy and scanning electron microscope–energy-dispersive spectrometer, respectively. And then the flame retardant and thermal degradation characteristics of all TPU composites were tested using smoke density test (SDT), cone calorimeter test (CCT) and thermogravimetric/fourier transform infrared spectroscopy, etc. The SDT results showed that HGM@[EOOEMIm][BF4] can significantly decrease the amount of smoke production. The CCT revealed that HGM@[EOOEMIm][BF4] can greatly enhance the flame retardant of TPU. The peak heat release rate value decreased from 1224.0 kW m−2 (TPU0) to 498.5 kW m−2 (TPU/HB2). The TG test showed that HGM@[EOOEMIm][BF4] can improve the thermal stability of TPU composites and promote the char formation in the combustion process of TPU. All results confirmed that HGM@[EOOEMIm][BF4] can make a great influence on the combustion and degradation of TPU.
