摘　　要：研究了一种无卤阻燃剂对聚乙烯(PE)膜的氧指数(OI)及拉伸强度、断裂伸长率、耐撕裂性等力学性能的影响。随着阻燃剂用量的增加,膜的氧指数明显增加,有效降低了燃烧速率、减少了熔滴和黑烟的产生;但膜的拉伸强度、断裂伸长率、耐撕裂性等力学性能都会降低。无卤阻燃剂的用量为20%~25%时,膜的综合性能相对较好。This paper studies the effect of a halogen-free flame retardant on the oxygen index(OI),tensile strength,fracture elongation and tear resistance of polyethylene(PE)films.With the increase of flame retardant dosage,the oxygen index of the films increases significantly,which effectively slows down the combustion rate and reduces the production of melting droplets and black smoke;but the film tensile strength,fracture elongation,tear resistance and other mechanical properties will decrease.The favorable dosage of the halogen-free flame retardant should be up to 20%~25%if calculated at 100%of total parts.
