摘　　要：通过表面接枝技术将流滴剂十八烷基二乙醇胺丙烯酸单酯(AAM)接枝到高岭土(Ka)表面,制得Ka与AAM接枝物(Ka-g-AAM);将Ka-g-AAM与线性低密度聚乙烯(LLDPE)熔融挤出,制备了Ka-g-AAM/LLDPE复合材料;利用FTIR、SEM、DSC和加速流滴仪等对Ka-g-AAM/LLDPE复合材料的结构和性能进行了表征。结果表明,与AAM/LLDPE和Ka-AAM/LLDPE复合材料相比,Ka-g-AAM/LLDPE复合材料中LLDPE的熔融温度、结晶温度和力学性能变化不大;Ka-g-AAM/LLDPE复合材料薄膜在60℃加速流滴期达23天,比AAM/LLDPE复合材料延长了4天。The eighteen alkyl diethanolamine acrylic monoester dripping agent(AAM)was grafted onto kaolin(Ka)by surface grafting,the grafting of AAM and Ka(Ka-g-AAM)was prepared.Then Ka-g-AAM/linear low density polyethylene(LLDPE)composites were prepared by melt extrusion.The structure and properties of Ka-gAAM/LLDPE were investigated by FTIR,SEM,DSC and acceleration dripping testing etc.The results indicate that AAM is grafted onto the surface of Ka.Compared with AAM/LLDPE and Ka-AAM/LLDPE composite,Ka-gAAM/LLDPE composites have inconspicuous changes on the melting temperature,the crystallization temperature and mechanical properties.The acceleration dripping duration of Ka-g-AAM/LLDPE composite films is 23 days at60℃,which is 4 days longer than that of AAM/LLDPE composite.
