| 摘 要： | 研究了在共聚甲醛中加入Ａｌ（ＯＨ）３或Ｍｇ（ＯＨ）２后，产物的阻燃性及力学性能。结果表明：Ａｌ（ＯＨ）３加入量占共聚甲醛的６０％时，产物完全不燃；Ｍｇ（ＯＨ）２的阻燃效果较差。加入硬脂酸锌可明显改进其流动性。二者并用可明显增加共混材料的强度及流动性。

| Abstract: | Flame retardancy and mechanical properties of acetal copolymer blended withAl(OH)3 or Mg(OH)2 were studied. The results indicated that the acetal copolymer containing 60% Al(OH)3 wasn't combustible. Flame retardancy of Mg(OH)2 was inferior to that of Al(OH)3. When Al(OH)3 was pretreated with aluminum coupling agent, the notch impact strength and tensile strength of blend would be improved and their flame retardancy would be not influenced by pretreatment. When pretreated Al(OH)3 and zinc stearate were added to the blend, a synergistic effect with respect to strength and flow would be observed. |
