| 摘 要： | 采用熔融共混挤出法制备了EVA／Al(OH)3纳米复合材料。用TEM、SEM分析了Al(OH)3粉体改性前后在EVA树脂中的分散性与相容性。研究了表面处理对复合材料阻燃与力学性能的影响，并对Al(OH)3阻燃机理进行了探讨。结果表明：采用钛酸酯偶联剂对粉体进行表面改性可有效改善其在树脂中的分散与结合情况，复合材料阻燃级别提高到UL94 V-1级，拉伸性能得到改善。

| Abstract: | EVA/Al(OH) 3 nanocomposites were prepared by melt-blending. The dispersion and compatibilization of the filler in EVA resin were characterized using SEM and TEM. The combustion behavior and mechanical properties of the composites were investigated,the flame retardancy mechanism of Al(OH) 3 was also probed. It was observed that surface modified Al(OH) 3 has better dispersion and adhesion in polymer matrix,and thus the flame retardancy and tensile properties of the nanocomposites were improved. |
