| 摘 要： | 采用氢氧化镁(MH)、膨胀石墨(EG)和有机蒙脱土(OMMT)为阻燃剂制备了无卤阻燃线性低密度聚乙烯(LLDPE),研究了OMMT对LLDPE/EG/MH阻燃性能和力学性能的影响。结果表明:少量OMMT的加入,可以有效改善LLDPE/EG/MH的力学性能、阻燃性能和热稳定性。当OMMT质量分数为3.0%时,LLDPE/EG/MH/OMMT的拉伸强度和冲击强度分别为1.4 MPa和26.5 kJ/m~2;极限氧指数为35.0%,符合UL-94 V-0级;其热释放速率峰值、平均热释放速度、生烟速率和总生烟量比LLDPE/EG/MH的低。

| Abstract: | Halogen-free flame-retardant linear low density polyethylene(LLDPE) was prepared with magnesium hydroxide(MH),expandable graphite(EG) and organophilic montmorillonite(OMMT).The effects of OMMT on the mechanical properties and flame retardancy of LLDPE/EG/MH were studied.The results show that a small amount of OMMT can improve the mechanical properties,flame retardancy and thermal stability of LLDPE /EG/MH.When the content of OMMT is 3.0%,the tensile strength and impact strength of LLDPE/EG/MH/OMMT are 11.4 ... |
