1)丙烯酸六氟丁脂与含双键的硅树脂按1：2～1.5：1混合均匀；
2)将混合均匀的共聚乳液配成质量分数为30％～60％的水混合液；
3)将尼龙经轴辊按一定速度经过上述共聚乳液，浸涂时间1min～30min，烘干温度50℃～90℃。
所述超双疏铝层的制备方法如下：
1)将铝箔按一定速度经不锈钢辊在丙酮溶液中清洗；
2)经丙酮和去离子水清洗并烘干的铝箔经0.1mol/L～1mol/L的HF酸溶液除氧化膜1min～10min；
3)将去除氧化膜的铝箔经0.5mol/L～4.0mol/L的盐酸刻蚀5～30min；
4)经去离子清洗烘干后，在30～50％的氟硅烷烃和乙醇混合溶液浸涂1min～30min。
进一步地，所述超疏水尼龙层、外粘合层、超双疏铝层、内粘合层和聚丙烯层分别依次通过压力作用粘合。
进一步地，所述外粘合层和内粘合层的材料均为：聚氨酯。
与现有技术比，本发明达到的有益效果是：
1.本发明包含的超疏水尼龙层，制备方法简单，疏水效果好。
2.本发明包含的超双疏铝层，经盐酸刻蚀和氟硅烷烃浸泡获得，制备方法环保且简单，能疏电解液和水。

测试1：
去离子水和电解液分别滴5uL的水分和电解液在超疏水尼龙层和超双疏铝层上，用视频光学接触角测量仪测量接触角，结果表1：
表1接触角测量
当接触角大于150°时，该材料表面具有超疏水结构。从表1可以看出，超双疏铝锂电池用塑膜的接触角比现有铝塑膜的接触角大，表明疏水和疏电解液性能比现有铝塑膜要好。

将超双疏锂锂电池用铝塑膜与现有铝塑膜经底侧封装后，注液一定量的电解液并顶封，再将其放入温度为65℃，湿度为95％的高温高湿箱中搁置90天，然后测量电解液含水量。电解液含水量如表2：
表2高温高湿测试
从表2中可以看出，高温高湿测试前电解液含水量为8.1ppm，经90天的高温高湿测试，实施例1的电解液含水量为10.6ppm，实施例2的电解液含水量为11.4ppm，实施例3的电解液含水量为12.5ppm；现有技术下的铝塑膜内的电解液含水量为13.4ppm，超双疏锂电池用铝塑膜防水性能比现有技术下的铝塑膜好。
