摘要:以膨胀型阻燃剂(IFR)和自制的有机蒙脱土(OMMT)协同阻燃剂对线型低密度聚乙烯(LLDPE)进行阻燃改性,研究了阻燃剂和协同阻燃剂对LLDPE燃烧性能、力学性能的影响。运用极限氧指数(LOI)和热重分析(TGA)表征了LLDPE的阻燃性能,通过扫描电子显微镜(SEM)观察燃烧残余物的炭层形貌。结果表明,OMMT的加入增强了LLDPE/IFR体系的阻燃性能和力学性能,且在一定程度上解决了体系燃烧时的熔滴和浓烟现象;当IFR用量为30份,有机蒙脱土用量为2%时,体系的极限氧指数达到25.2%,燃烧残余物形成致密的炭层。
Linear low density polyethylene (LLDPE) was modified by intumescent flame retardant (IFR) and organic montmorillonite (OMMT). The synergistic influences of IFR and OMMT on the flammability, mechanical properties of flame-retardant LLDPE were investigated. The flammability and degradation progress of the composites and the obtained charred layers were analyzed by limiting oxygen index (LOI), TGA and SEM. The results show that the addition of OMMT deteriorates the flammability, increases mechanical properties of LLDPE/IFR, and decreases the melt dripping and dense smoke to some extent. When the content of IFR and OMMT is 30phr and 2 % respectively, the LOI value of the system is 25.2 %, and the sample could form compact charred layer after burning.
