摘　　要：以聚磷酸胺(APP)为阻燃剂,与阻燃树脂复配,添加到PE基木塑复合材料(WPC)中,制备了阻燃木塑复合材料。用氧指数仪(OI)、锥形量热分析(CONE)研究了WPC的各项阻燃性能。结果表明:阻燃WPC的OI达到38%,比普通木塑材料提高了58.33%,成炭率高于20%,点火时间(TTI)达到30 s;通过自制的相容剂Ⅱ(EVA/VC-g-MA)可以有效提高PVC与PE的相容性,产品的力学性能与普通木塑材料相比变化不大。研究表明,WPC的阻燃性能和力学性能随APP用量、阻燃树脂配方不同而变化,但TTI和有害气体变化不大。Flame retarded WPC were prepared by using APP and flame retardant resin composed withwood flour and PE. The OI, CONE and mechanical properties of WPC were characterized, and the re-sults show that the OI is 38%, increase by 58. 33%, the ratio of remaining carbon above 20%, the TTIis 30 s and through self-made compatibilizer Ⅱ（EVA/ VC-g-MA） can effectively improve the compati-bility of PVC and PE, the mechanical properties are less affected. The results also indicate that contentof APP and formulae of flame retardant resin affect on the flame retardancy and mechanical properties ofWPC, but TTI and noxious gas are no obviously change.
