Description

一种高阻隔复合薄膜
技术领域
本发明涉及复合薄膜技术领域，具体涉及一种高阻隔复合薄膜。
背景技术
PET薄膜具有很好的透明性、较好的气密性和中等的防潮性；同时它在较宽的温度范围内具有优良的物理机械性能，长期使用温度可达120℃，电绝缘性优良；还具有很好的抗蠕变性、耐疲劳性和尺寸稳定性，是一种性能优异的包装薄膜，被广泛应用于各行各业。但目前现有薄膜对水分、空气的阻隔性能偏低，使得产品的保质期偏低，达不到预期的保质效果，所以，为了满足市场需求，增强薄膜对水分、空气的高阻隔性能，继续研制出一种高阻隔的复合薄膜。
发明内容
针对上述存在的问题，本发明提出了一种高阻隔复合薄膜，通过对阻隔层进行共混、插层双改性，大大提高了薄膜对气体、水分的阻隔效果，显著延长了包装商品的保质期，同时外层的硅溶胶在提高PA性能的同时也提高了防水抗污的效果，进一步保证了优异的阻隔效果。
为了实现上述的目的，本发明采用以下的技术方案：
一种高阻隔复合薄膜，其特征在于，包括外层、阻隔层和内层三个复合结构层，所述涂层包括以下百分含量的组分制成：PA75-80％、纳米硅溶胶20-25％，所述阻隔层包括以下百分含量的组分制成：PET30-60％、PEN 8-18％、纳米改性蒙脱土30-60％，所述内层包括以下百分含量的组分制成：PE 30-60％、PP 30-55％、成核剂2-4％、相容剂5-15％。
优选的，高阻隔复合薄膜，包括外层、阻隔层和内层三个复合结构层，所述涂层包括以下百分含量的组分制成：PA78-80％、纳米硅溶胶20-22％，所述阻隔层包括以下百分含量的组分制成：PET 40-60％、PEN 8-15％、纳米改性蒙脱土30-50％，所述内层包括以下百分含量的组分制成：PE 35-50％、PP 30-50％、成核剂3-4％、相容剂8-10％。
优选的，所述纳米改性蒙脱土的制备原料为钠基蒙脱土、醋丙乳液、去离子水、对氨基苯甲酸盐。
优选的，所述纳米改性蒙脱土制备方法如下：1)将钠基蒙脱土与适量去离子水配置成悬浮液，先在室温下高速搅拌30-40min，然后升温至60℃高速搅拌分散至钠基蒙脱土完全溶胀；2)再向其中加入对氨基苯甲酸盐，升温至90-95℃，恒温搅拌1-1.2h，然后经冷却、抽滤、真空干燥、研磨得纳米蒙脱土；3)将纳米蒙脱土与适量去离子水配置成悬浮液，具体为先在室温下高速搅拌30-40min，然后升温至50℃进行一次超声处理10-15min，然后将醋丙乳液滴加入其中，调节温度为35℃搅拌分散1.5-2h，再进行二次超声处理10-15min，然后经冷却、抽滤、真空干燥、研磨即得纳米改性蒙脱土。
优选的，所述成核剂为质量比1:3:6的氧化铈、滑石粉和聚乙二醇的组合物。
优选的，所述相容剂为质量比PE-g-MAH、PP-g-MAH的组合物。
优选的，高阻隔复合薄膜的制备方法，步骤如下：
1)将PA切片与纳米硅溶胶放入混料机中共混，在100-120℃条件下保持3-4h，得外层料；将PET切片、PEN切片与纳米改性蒙脱土放入混料机中共混，在100-120℃条件下保持3-6h，得阻隔层料；将PP切片、PE切片、相容剂、成核剂放入混料机中共混，在100-120℃条件下保持3-6h，得内层料；
2)将外层料、阻隔层料、内层料采用多层共挤工艺挤出成型，然后经拉伸成膜。
