摘　　要：通过熔融共混制备了高密度聚乙烯(HDPE)/湿法表面改性纳米氢氧化镁(MH)/微囊红磷(MRP)无卤阻燃复合材料,研究了原料配比及表面改性对体系性能的影响。得出结论:湿法改性MH有效地将偶联剂附在MH上,但也使得粒子尺寸略微增大。通过SEM观察发现表面改性有利于阻燃剂在树脂中的分散。加入MRP和MH产生协同效应,有效地提高了体系的阻燃性,且对力学性能影响有限。HDPE/MH/MRP质量比为100/50/7.5时可得到很好的阻燃效果和力学性能。HDPE/ nano-magnesium hydroxide （MH） surface modified in solvent / microen-capsulized red phosphorus （MRP） non-halogen flame-retarded composites was prepared by meltblending. The influence of the ratio of material, surface modification on properties of composites was studied. The results showed： the surface modification for MH in solvent makes the modifiers adhere to the surface of MH, the particles size increase slightly. The pictures taken by SEM shows that the surface modification is propitious to the dispersing of flame retardant in resin. Adding MRP to MH bring synergistic effect in improving the flame retardancy, the influence on mechanical properties is unconspicuous. When the ratio of HDPE/MH/MRP is 100/50/7.5, the composites own good flameretardant and mechanical properties.
