%X 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-g-AAM/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-g-AAM/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 at 60℃, which is 4 days longer than that of AAM/LLDPE composite. 十三五国家重点研发计划（2016YFB0302401
