Abstract

本发明公开了一种抗静电PET薄膜，所述抗静电PET薄膜自下而上依次包括第一导电层、PET基层、第二导电层、耐磨层，所述第一导电层和第二导电层各自为附着有碳纳米管的PET层；所述耐磨层为附着有耐摩擦剂的PET层。本发明在基材的两面均设置导电层，可以消除PET膜两面的静电，在用于包装材料时更容易操作，可以防止静电累积导致的电击、放电等潜在危险，也可防止静电累积导致的污染、灰尘等。在PET膜的表面设置耐磨层，可以降低薄膜的耐摩擦系数，提高薄膜耐久性。

Description

一种抗静电PET薄膜
技术领域
本发明涉及一种抗静电PET薄膜。
背景技术
由于聚对苯二甲酸乙二醇酯(PET)具有许多优异的性能，因而PET薄膜及薄片广泛应用于食品、医药、纤维、电子元件等包装材料，另外也搭乱盖地被使用作磁带、软塑磁盒、照相用底片等。
但是PET薄膜受到摩擦产生静电现象，常会引起粘回车、污染、粘接不良、花斑、质量下降等麻烦，因此，需要对薄膜进行抗静电处理。
发明内容
本发明提供了一种抗静电PET薄膜。
本发明采用的技术方案是：
一种抗静电PET薄膜，所述抗静电PET薄膜自下而上依次包括第一导电层、PET基层、第二导电层、耐磨层，所述第一导电层和第二导电层各自为附着有碳纳米管的PET层；所述耐磨层为附着有耐摩擦剂的PET层。
进一步，所述第一导电层、PET基层、第二导电层、耐磨层通过共挤出制得所述抗静电PET薄膜。
进一步，所述第一导电层的厚度为1～100μm，优选10～50μm；PET基层的厚度为10～500μm，第二导电层的厚度为1～100μm，优选10～50μm；耐磨层的厚度为1～50μm，优选5～20μm。
所述第一导电层和第二导电层的表面电阻率在103～106Ω。
本发明中，所述第一导电层和第二导电层各自为附着有碳纳米管的PET层，可采用添加有(可以是内掺或者附着方式)碳纳米管的PET材料制作而成。
所述耐磨层为附着有耐摩擦剂的PET层，可采用添加有(可以是内掺或者附着方式)耐摩擦剂的PET材料制作而成。
所述耐摩擦剂为纳米无机粉体，如纳米碳酸钙、纳米硅酸钙、纳米二氧化硅、纳米黏土等。
本发明提供的抗静电PET薄膜可按以下方法制得：
(1)制作添加有碳纳米管的第一导电母粒：取PET基体材料和碳纳米管，碳纳米管的添加量为1～10％，其中还可加入润滑剂、抗氧剂等助剂，挤出造粒制得第一导电母粒；
(2)制作添加有碳纳米管的第二导电母粒：同步骤(1)
(3)制作添加有耐摩擦剂的耐磨母粒：取PET基体材料和耐摩擦剂，耐摩擦剂的添加量为1～5％，其中还可加入润滑剂、抗氧剂等助剂，挤出造粒制得耐磨母粒；
(4)PET基材母粒、第一导电母粒、第二导电母粒、耐磨母粒按照图1所示的上下层次顺序，多层共挤出制得。具体的，通过多台的挤出机分别使每种母粒熔融塑化后，注入同一模头中，然后经过进一步加工处理(吹塑、流延或双向拉伸)，制得多层复合抗静电PET薄膜。
本发明在基材的两面均设置导电层，可以消除PET膜两面的静电，在用于包装材料时更容易操作，可以防止静电累积导致的电击、放电等潜在危险，也可防止静电累积导致的污染、灰尘等。在PET膜的表面设置耐磨层，可以降低薄膜的耐摩擦系数，提高薄膜耐久性。
