摘　　要：以聚烯烃弹性体(POE)为主要增韧剂制备不同POE含量的聚丙烯(PP)复合材料,比较不同POE含量对PP复合材料阻燃性能和耐久性能的影响,进一步探究其作为建筑材料的适用性。结果表明:添加质量分数6%POE的PP复合材料在阻燃性能方面表现最优,表现出最高的极限氧指数值(29.9%),最低的总热释放量(128.3 MJ/m^(2))以及热释放速率(574.7 k W/m^(2))。在耐久性能测试中,相比纯聚丙烯材料,添加质量分数6%POE的PP复合材料也能够保持优异的阻燃性能和力学性能,在经过72 h的老化之后,其力学性能和阻燃性能的下降程度最低,因此能够作为建筑材料,具有广泛应用的应用前景。Polyolefin elastomer(POE)was used as the main toughening agent to prepare polypropylene(PP)composites with different POE contents.The effects of different POE contents on the flame retardancy and durability of PP composites were compared,and their applicability as building materials was further explored.The results showed that the PP composite with 6%POE content exhibited the best flame-retardant performance,with the highest limiting oxygen index(29.9%)and the lowest total heat release(128.3 MJ/m^(2))and heat release rate(574.7 kW/m^(2)).In the durability tests,compared with pure polypropylene material,the PP composite with 6%POE content also maintained excellent flameretardant and mechanical properties.After 72 h of aging,it showed the lowest degree of decline in mechanical and flameretardant properties.Therefore,it has the potential to be used as a building material with broad application prospects.
