| 摘 要： | 采用水热法和模板法制备了新型阻燃剂Ni MoO4/Co-Ni LDH/SiO2,将其加入喷涂聚脲(SPUA)中制备了SPUA复合材料。通过X射线衍射和X射线光电子能谱,对Ni MoO4/Co-Ni LDH/SiO2进行物相组成和元素分析;利用锥形量热仪(CONE)对材料进行阻燃性能表征。结果表明,添加质量分数2%的Ni MoO4/Co-Ni LDH/SiO2时,SPUA复合材料热释放速率峰值与总CO释放量较纯SPUA分别下降了26.2%和38.4%,阻燃性能得到较大提升。

| Abstract: | The new flame retardant Ni MoO4/Co-Ni LDH/SiO2was prepared by hydrothermal method and template method.The spray polyurea composite was prespared by Ni MoO4/Co-Ni LDH/SiO2adding to spray polyurea.The phase composition and elemental analysis of Ni MoO4/Co-Ni LDH/SiO2were characterized by X-ray diffraction and X-ray photoelectron spectroscopy.Cone calorimeter(CONE)was used to characterize the flame retardancy of the materials.The results showed that the peak heat release rate(PHRR)and total CO release were reduced by26.2%and 38.4% when 2% mass fraction of Ni MoO4/Co-Ni LDH/SiO2was added.The flame retardancy of spray polyurea was greatly improved. |
