| 摘 要： | 采用沉淀法制备双层包覆红磷（DERP）,通过FESEM、XPS、TG、吸湿性测试对其进行了表征。结果表明：红磷表面形成均匀的包覆层,包覆率达到97．18％,包覆后的红磷吸湿性也得到较大改善,着火点提高到430℃。将阻燃剂DERP添加到聚丙烯中,质量分数为5％时,阻燃级别可达到UL94V-0级。

| Abstract: | The Double Encapsulated Red Phosphorus （DERP） which was prepared by deposition sedimentation method was investigated by FESEM, XPS, and TG analysis means. The result indicated that an uniform layer of encapsulation was formed, 97.18% of the red phosphorus was encapsulated, the water absorption rate was lowered apparently and the ignition point of red phosphorous was improved to 430 ℃. Adding the DERP to the polypropylene （PP） for fire retardant, the flame retardant reached UL 94 V-0 class after adding 5% DERP. |
