本发明解决其技术问题所采用的技术方案是：聚乙烯增抗静电爽滑母粒，其组分按质量百分数配比为：聚乙烯40％～75％、抗粘连剂5％～15％、爽滑剂10％～20％、抗静电剂10％～20％、分散剂1％～3％、偶联剂0.5％～1％、抗氧剂0.1％～1％。
所述的抗粘连剂为粒径在2～4μm之间的轻质二氧化硅。
所述的爽滑剂为油酸酰胺、芥酸酰胺、硬脂酸钙中的一种或几种的混合物。
所述的抗静电剂为脂肪酸甘油单酯、脂肪酸甘油二酯或脂肪酸聚乙二醇酯中的一种。
所述的分散剂为聚乙烯蜡、氧化聚乙烯蜡(EVA蜡)或乙撑双硬脂酸酰胺(EBS)中的一种。
所述的偶联剂为硅烷偶联剂或钛酸酯偶联剂。
所述的抗氧剂为主抗氧剂1010与辅助抗氧剂168的复配物。
上述的聚乙烯增抗静电爽滑母粒的制备方法，包括以下步骤：
(1)将各组分按重量配比称好待用；
(2)将抗粘连剂和偶联剂加入转速在500～1500转/分钟的高速混合机中，混合3～5分钟，再在高速混合机中加入聚乙烯、爽滑剂、抗静电剂、分散剂和抗氧剂，使一起充分混合2～10分钟；
(3)将上述混合好的物料加入双螺杆挤出机充分熔融共混，熔融温度控制在160℃～200℃，螺杆转速为100～300转/分钟，通过双螺杆挤出机的剪切、混炼10～15分钟，然后挤出、冷却、造粒、干燥即得本发明的聚乙烯增抗静电爽滑母粒。
本发明的有益效果是，与现有技术相比，采用本发明制得的母粒，应用于制造聚乙烯薄膜或吹膜制品中，具有良好的抗粘连爽滑效果和抗静电效果，而且制品表面光洁度显著改善，特别适用于自动包装膜、液体包装膜和农地膜等，具有较好的应用前景。
