摘要： 为提升硅橡胶泡沫（SiFs）的阻燃性能，通过直接沉淀法制备了植酸锰（PA-Mn），并利用傅里叶变换红外光谱、X射线光电子能谱和扫描电子显微镜对其进行了表征，分别将质量分数1%、3%、5%、7%、9%的PA-Mn添加在SiFs中，采用极限氧指数（LOI）测试仪、垂直燃烧测试仪（UL-94）、锥形量热仪和热重分析仪测试分析了SiFs的阻燃抑烟性能。结果表明：通过直接沉淀法所制备的PA-Mn具有较高纯度。PA-Mn能显著提升SiFs的阻燃抑烟性能，添加量为3%时SiFs的阻燃抑烟性能最佳，LOI为28.2%，UL-94等级达到V-0级，热释放速率峰值、总热释放量和火灾增长指数较纯SiFs分别降低27.4%、16.1%和36.4%，火灾性能指标较纯SiFs提高22.2%，烟密度等级、最大烟密度、总产烟量较纯SiFs分别降低5.5%、19.8%、16.6%。

Abstract: In order to improve the flame retardant performance of silicone rubber foam (SiFs), manganese phytate (PA-Mn) was prepared by direct precipitation method, and Fourier transform infrared spectroscopy, X-ray optoelectronic spectrum and scanning electron microscope.PA-Mn with the mass fraction of 1%, 3%, 5%, 7% and 9% was added to SiFs, and the performance of ultimate oxygen index (LOI) tester, vertical combustion tester (UL-94) and cone thermometer were analyzed. The results show that the PA-Mn prepared by direct precipitation method has high purity. PA-Mn can significantly improve the flame retardant and smoke suppression properties of SiFs. When the addition amount is 3%, the flame retardant and smoke suppression properties of SiFs are the best. The LOI is 28.2%, reaching UL-94 V-0 grade. The peak heat release rate, total heat release and fire growth index are 27.4%, 16.1 % and 36.4% lower than those of pure SiFs, respectively. The fire performance index is 22.2% higher than that of pure SiFs, and the smoke density grade, maximum smoke density and total smoke production are 5.5%, 19.8% and 16.6% lower than those of pure SiFs, respectively.
