摘　　要：采用等量比的聚乙二醇-400/十二烷基硫酸钠(PEG-400/SDS)作为复合改性剂,以硝酸镁和氢氧化钠为原料,制备了改性Mg(OH)_(2)。将改性Mg(OH)_(2)与三聚氰胺聚磷酸盐(MPP)复配应用于聚酰胺66(PA66)中,研究了复合材料的阻燃性能和力学性能。结果表明:复配阻燃剂提高了PA66的阻燃性能,且对PA66的力学性能影响较小。Using polyethylene glycol-400/sodium dodecyl sulfate(PEG-400/SDS) in the same ratio as the composite modifier, and magnesium nitrate and sodium hydroxide as raw materials, the modified magnesium hydroxide was prepared. The modified magnesium hydroxide and melamine polyphosphate(MPP) were compounded in polyamide 66(PA66). The flame retardancy properties and mechanical properties of PA66 were studied.The results show the flame retardancy properties of PA66 is improved, and the mechanical properties of PA66 are influenced less.
