Abstract
本发明公开了一种热缩流延PE膜及其制备方法。PE膜包括热缩外层和增韧内层，热缩外层包括低密度聚乙烯、高密度聚乙烯、聚乙烯蜡、聚乙烯醇、脂肪醇聚氧乙烯醚、纳米二氧化硅、增粘剂、增塑剂、爽滑剂和偶联剂；增韧内层包括低密度线性聚乙烯、乙烯‑乙烯醇共聚物、聚乙烯接枝马来酸酐、纳米二氧化硅、抗氧剂、光稳定剂、增粘剂和偶联剂。制备时，先分别制备热缩外层和增韧内层，然后再将热缩外层和增韧内层一起放入流延机中进行共挤流延拉伸，即得热缩流延PE膜。本发明制备的热缩流延PE膜具有良好的力学性能和热收缩性能。
Description
技术领域
本发明属于高分子薄膜技术领域，具体涉及一种热缩流延PE膜及其制备方法。
背景技术
聚乙烯(PE)是乙烯经聚合制得的一种热塑性树脂，也包括乙烯与少量α-烯烃的共聚物。聚乙烯具有优异的化学稳定性，室温下能耐酸和碱，但容易受光、热氧化，在紫外线下还可以发生光降解。聚乙烯还具有优秀的力学性能，其结晶部分赋予聚乙烯较高的强度，非结晶部分赋予其良好的柔韧性。
PE热收缩膜广泛适用于烟酒类、易拉罐类、矿泉水类、各种饮料类、布匹等产品的整件集合包装，其具有柔韧性好，抗撞击、抗撕裂性强，不易破损、不怕潮、收缩率大等优点，其对堆放在托板上的货物进行缠绕包装，使包装物更加稳固整洁，更超强防水，被广泛使用于外贸出口、造纸、五金、塑料、化工、建材、食品医药行业。
现有的PE热收缩膜在强度和韧性方面有局限，一般采用HDPE来提高强度，但是HDPE会使热收缩膜的韧性大幅度下降，烟类包装一般整条包装后再集合包装，但是对于两条以上的集合包装PE热收缩膜，现有的PE热收缩膜在包装运输过程中容易破裂，且损耗量大，因此如何提高热收缩膜的拉伸和韧度，以及节约集合包装所用PE热收缩膜，成为了亟待解决的问题。
发明内容
针对上述现有技术，本发明提供一种热缩流延PE膜及其制备方法，以解决现有热缩膜强度低以及热缩性能差的问题。

进一步，抗氧剂为亚磷酸酯或硫代酯；光稳定剂为受阻胺光稳定剂。
进一步，增粘剂为羧甲基纤维素钠；偶联剂为钛酸酯偶联剂和硅烷偶联剂的共混物。
本发明提供了上述热缩流延PE膜的制备方法，制备方法包括以下步骤：
S1：将配方用量的低密度聚乙烯、聚乙烯蜡、聚乙烯醇、脂肪醇聚氧乙烯醚、纳米二氧化硅、增粘剂、增塑剂、爽滑剂和偶联剂加入混合机中混合，得到混合物a，将得到的混合物a置于双螺杆挤出机挤出制得母料A，将得到的母料A与高密度聚乙烯在捏合机中捏合后进入密炼机中密炼得热缩外层；

(2)本发明热缩流延PE膜中各组分协同作用，在赋予膜层良好加工性能和力学性能的同时，还能有效改善高分子膜层的热收缩性能，所得PE膜在加热时可快速收缩，并产生较大的收缩力，使包装更加紧密。
(3)调整偶联剂的配比，可以改善无机物与有机物之间的相容性，提高了PE膜的机械性能及热缩性能。
