摘要
通过热重分析（TGA）和红外光谱（FTIR）对一种新型磷系阻燃剂异丁基次磷酸铝（A-MBPa）的热降解行为进行了详细研究,并用气相色谱-质谱法（GC-MS）、FTIR和能谱分析（EDS）等方法对A-MBPa的热裂解产物进行了分析。TGA结果表明,在氮气气氛下,A-MBPa的初始分解温度为369.31℃,残炭率为45.54%。FTIR和GC-MS结果表明,在热分解前期,A-MBPa会释放气相物质,而在后期降解过程中会形成更多的炭层,起到隔热、隔氧的作用。因此,A-MBPa的这种降解行为有利于提高聚合物的阻燃性能。
The thermal degradation behavior of a novel phosphorus-containing compound of aluminum mono-isobutylphosphinate（A-MBPa） was investigated by thermogravimetric analysis（TGA） and FTIR in detail. In addition, the pyrolysis behavior of A-MBPa was examined by gas chromatography-mass spectrometry（GC-MS）, FTIR and energy dispersive spectrum（EDS）. The TGA results show that A-MBPa has an initial decomposition temperature of 369.31℃ and a high residue（45.54%） remained in the end of thermal decomposition under nitrogen atmosphere. It is believed that this degradation behavior is benefi cial for enhancing its efficiency when applied as a flame retardant for polymers.
