Abstract

An eco-friendly hydrophobic flame retardant, ammonium salt of octadecyl phosphate (AMOP) was synthesized and its structure was verified by 1HNMR, 13CNMR and 31PNMR. AMOP imparted flame retardancy and superhydrophobicity to cotton fabrics simultaneously. The water contact angles and limiting oxygen index values of treated cotton reached 161.8° and 27%, respectively. After 30 laundering cycles, the hydrophobicity sustained very well. Thermogravimetric analysis and thermogravimetric-infrared spectroscopy suggested AMOP changed the thermal decomposition path of cotton fibers and the treated sample released less flammable gas during the thermal decomposition process. Cone calorimetry results showed the total heat release and the heat release rate of treated cottons were much lower than those of control cottons. Fourier-transform infrared spectroscopy, energy dispersive X-ray analysis and X-ray photoelectron spectroscopy suggested the AMOP successfully grafted on cotton fabrics through P-O-C groups. Scanning electron micrography showed AMOP caused a rough surface.

同时在棉织物上赋予超疏水性和阻燃性

摘要

合成了一种环保型疏水性阻燃剂十八烷基磷酸铵盐(AMOP),并通过1 HNMR,13 CNMR和31核磁共振 AMOP同时赋予棉织物阻燃性和超疏水性。处理后的棉花的水接触角和极限氧指数值分别达到161.8°和27%。在30次洗涤循环后,疏水性维持得很好。热重分析和热重红外光谱分析表明,AMOP改变了棉纤维的热分解路径,并且在热分解过程中,处理过的样品释放出较少的可燃气体。锥量热法的结果表明,处理后的棉花的总放热和放热率远低于对照棉。傅里叶变换红外光谱,能量色散X射线分析和X射线光电子能谱表明AMOP通过POC基团成功地嫁接到了棉织物上。
