A series of fluorine-containing polyurethane elastomers (FPUEs) were synthesized from 2,2-bis[4-(4-amino-2-trifluoromethylphenoxy)-phenyl]hexafluoropropane (BAFPF6P), which was made from 2-chlorobenzotrifluoride and 2,2-bis(4-hydroxyphenyl) hexafluoropropane and characterized by Fourier transform infrared spectroscopy, nuclear magnetic resonance, thermogravimetric analysis, microscale combustion colorimeter and contact angle measurement. The results show that the fluorine-containing polyurethane elastomers prepared from BAFPF6P have good thermal stability and low surface tension. Furthermore, fluorine-containing polyurethane elastomers also exhibit good flame retardance and the peak heat release rate and total heat released of fluorine-containing polyurethane elastomer based on BAFPF6P are much lower than those of polyurethane elastomer without the fluorine element.
以2,2-双[4-(4-氨基-2-三氟甲基苯氧基)-苯基]六氟丙烷(BAFPF6P)为原料,合成了一系列含氟聚氨酯弹性体(FPUE),该产品由2-氯三氟苯和2,2 -双(4-羟基苯基)六氟丙烷,并通过傅里叶变换红外光谱、核磁共振、热重分析、微型燃烧比色计和接触角测量进行表征。结果表明,以BAPFF6P制备的含氟聚氨酯弹性体具有良好的热稳定性和较低的表面张力。此外,含氟聚氨酯弹性体还表现出良好的阻燃性,基于BAFPF6P的含氟聚氨酯弹性体的峰值放热率和总放热量均远低于不含氟元素的聚氨酯弹性体。
