采用“一锅法”,以磷酸和哌嗪为原料制备了膨胀型阻燃剂焦磷酸哌嗪,利用傅里叶变换红外光谱对产物进行了表征。将自制的焦磷酸哌嗪与市场上的优质竞品进行了性能比较,结果表明其热稳定性、元素含量和白度均能达到优质品标准。将自制的焦磷酸哌嗪添加到硅橡胶中,硅橡胶的极限氧指数从22.8%增加到27.2%,阻燃等级达到V-0级,拉伸强度增大1倍。本方法可以实现焦磷酸哌嗪的绿色制备。
- Abstract:
-
The expansive flame retardant pipe-razine pyrophosphate was synthesized via "one pot method" using phosphoric acid and piperazine as raw materials. Fourier transform infrared spectroscopy was employed to characterize the resulting product. The properties of self-made piperazine pyrophosphate was compared with high-quality competitor in the market. The results revealed that self-made piperazine pyrophosphate met superior standards in terms of thermal stability, element content, and whiteness. When added into silicone rubber, self-made piperazine pyrophosphate improved significantly its limiting oxygen index from 22.8% to 27.2%, achieving a V-0 flame retardant grade while doubling its tensile strength. This method could achieve green preparation of piperazine pyrophosphate.
