摘　　要：制备了微胶囊红磷/季戊四醇/三聚氰胺膨胀型阻燃剂（IFR）。采用吸湿性、抗氯化性、SEM、TG等测试方法对阻燃剂进行了表征。结果表明：微胶囊红磷的吸湿性减小、抗氯化性增强；TG分析显示，微胶囊红磷在385-422℃、470-553℃有两个失重阶段；600℃时，未包覆红磷残重仅为6％，而微胶囊包覆红磷的残重为12％；微胶囊红磷膨胀型阻燃齐的量佳组成为：微胶囊红磷；季戊四醇；三聚氰胺=4．00：0．75：2．00（摩尔比）；500℃下，IFR残重高达65.06％；当IFR添加量为30％时，阻燃环氧树脂的氧指数从未添加IFR时的19．0％提高到26．3％。The microencapsulated red phosphorus （MRP）/ pentaerythritol （PER）/ melamine （MEL） intumescent flame retardant （IFR） was prepared. The flame retardant was characterized by moisture absorption test, oxidation resistance test, SEM and TG analysis. The results show that： the moisture absorption of MRP decreases, the oxidation resistance of MRP increases; MRP has two weight loss stages 385-422℃ and 470-553℃ determined by TG analysis; at 600 ℃ , the residual weight of unencapsulated red phosphorus is only 6%, while the residual weight of MRP is 12%; the optimum mole proportion of the compositions of IFR is MRP：PER：MEL=4.00：0.75：2.00; at 500 ℃, the residual weight of IFR is up to 65.06%; when IFR content is 30%, the OI of flame retarded epoxy resin increases from 19% （without IFR） to 26.3%.
