Description

一种表面胍基修饰的BOPA复合薄膜及其制备方法
技术领域
本发明涉及包装薄膜技术领域，具体为一种表面胍基修饰的BOPA复合薄膜及其制备方法。
背景技术
尼龙经过双向拉伸得到的BOPA薄膜，具有优异的力学性能和阻隔性，广泛用于商品包装。虽然BOPA薄膜的分子链中含有极性酰胺基，但在印刷前仍需进行电晕处理，提高薄膜对印刷油墨的润湿性和粘附性。随着储存时间的延长，BOPA薄膜表面电晕处理的效果会逐渐衰退，影响后续印刷的牢固度。此外，BOPA薄膜具有很高的透光率，无法阻隔光线。
发明内容
本发明的目的在于提供一种表面胍基修饰的BOPA复合薄膜及其制备方法，解决了BOPA薄膜需要印前电晕处理，油墨附着性差，不阻隔光线的问题。
为实现上述目的，本发明提供如下技术方案：
一种表面胍基修饰的BOPA复合薄膜，表面胍基修饰的BOPA作为表面印刷层，涂布沸石咪唑酯骨架结构材料乳液作为中间阻隔层，聚乙烯薄膜作为内部热封层。
本发明优选的，所述沸石咪唑酯骨架结构材料乳液中沸石咪唑酯骨架结构材料含量为2-10wt％的均匀分散的丙烯酸乳液。
一种表面胍基修饰的BOPA复合薄膜的制备方法，包括以下步骤：
步骤一：将低温等离子体处理的BOPA薄膜浸泡于pH为8-10的碱性水溶液中，加热至40-70℃，反应3-18小时，取出BOPA薄膜，用去离子水洗涤至中性，得到表面含有氨基和羟基的BOPA薄膜；
步骤二：将步骤一处理的BOPA薄膜放入二氧化硫脲水溶液中，加热至40-90℃，反应1-24小时，冷却、洗涤、干燥后得到表面胍基修饰的BOPA薄膜；
步骤三：在表面胍基修饰的BOPA薄膜上涂布沸石咪唑酯骨架结构材料乳液，鼓风干燥；
步骤四：在沸石咪唑酯骨架结构材料乳液涂布层上热复合聚乙烯薄膜，得到表面胍基修饰的BOPA复合薄膜。
本发明优选的，所述二氧化硫脲水溶液中二氧化硫脲的摩尔浓度为0.01-0.5mol/L。
与现有技术相比，本发明的有益效果是：
胍基是一种阳离子基团，具有很强的质子化能力和抑菌性，可以与染料中的阴离子基团产生静电吸引。利用胍基改性剂与活化尼龙薄膜表面的氨基反应，对BOPA薄膜进行胍基修饰，可以有效提高印刷染料的附着性，减少印刷故障，同时赋予BOPA薄膜抑菌性。
沸石咪唑酯骨架结构材料是一种高孔隙率和大比表面积的纳米材料，具有很好的气体吸附性和遮光性。将沸石咪唑酯骨架结构材料乳液涂布于薄膜表面，可以有效阻隔可见光，提高薄膜的气体阻隔性。
