摘　　要：首先合成了硅烷型离子液体偶联剂(GWIL),然后分别用偶联剂铝酸酯、GWIL对碳酸钙(CaCO3)晶须进行表面处理,将处理后的CaCO3晶须和甲基丙烯酸缩水甘油酯接枝乙烯-辛烯共聚物(POE-g-GMA)、聚丙烯(PP)进行熔融共混。力学性能、热失重分析(TGA)、差示扫描量热仪(DSC)、扫描电子显微镜(SEM)等测试结果表明:POE-g-GMA的加入提高了PP/CaCO3晶须复合材料的拉伸强度、冲击强度和热稳定性;同时,GWIL对CaCO3晶须的处理效果要优于铝酸酯。A silane-type ionic liquid coupling agent(GWIL)was prepared,and then the calcium carbonate(CaCO 3)whiskers were surface-treated with coupling agent aluminate and GWIL.The glyceride grafted ethylene-octene copolymer(POE-g-GMA)and polypropylene(PP)were melt blended with CaCO 3 whiskers.Mechanical properties,thermogravimetric analysis(TGA),differential scanning calorimetry(DSC),scanning electron microscopy(SEM)measurements showed that the addition of POE-g-GMA improves the tensile strength,toughness and thermal stability of PP/CaCO 3 whisker composites.At the same time,GWIL is superior to aluminate in the treatment of CaCO 3.
