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。

Abstract

HDPE/ nano-magnesium hydroxide ( MH ) surface modified in solvent / microencapsulized 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.
