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UL 94 V-0级。
채용침정법제비쌍층포복홍린（ DERP），통과FESEM、 XPS、 TG、흡습성측시대기진행료표정。결과표명：홍린표면형성균균적포복층，포복솔체도97.18％，포복후적홍린흡습성야득도교대개선，착화점제고도430℃。장조연제DERP첨가도취병희중，질량분수위5％시，조연급별가체도UL 94 V-0급。
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.
