Description

高阻隔聚脂薄膜及生产方法
技术领域
本申请涉及高阻隔聚脂薄膜领域，具体是高阻隔聚脂薄膜及生产方法。
背景技术
镀铝膜是很好的阻隔性材料，常常用于食品保鲜袋的制备。可以大大减少资源和能源的消耗。但是随着工业包装行业的飞速发展，对镀铝聚酯薄膜的阻隔性要求也越来越高，传统的镀铝聚脂薄膜通过提高镀铝层的厚度来提高阻隔性，但单纯增加镀铝层的厚度又会影响到聚脂薄膜本身的光学、力学性能。
发明内容
本申请的目的在于提供高阻隔聚脂薄膜，它解决了传统镀铝膜满足不了阻隔性要求的问题，通过在薄膜基层与镀铝层之间涂布涂布层，使得镀铝薄膜阻隔性显著增长。
本申请为实现上述目的，通过以下技术方案实现：
高阻隔聚脂薄膜，包括有薄膜基层，所述薄膜基层上涂有涂布层，所述涂布层上附着有镀铝层；所述涂布层为丙烯酸类涂层材料、聚酯类涂层材料和聚氨酯类涂布材料的混合物，并添加异氰酸酯类交联剂进行交联。
进一步的，所述丙烯酸类涂层材料玻璃化转变温度为34~36℃，所述聚酯类涂层材料玻璃化转变温度为39~41℃，所述聚氨酯类涂布材料玻璃化转变温度为38~41℃。
进一步的，所述涂布层厚度为0.04~0.9g/m²。
进一步的，以100质量份计，所述丙烯酸类涂层材料为15~32份，所述聚酯类涂层材料为30~45份，所述聚氨酯类涂布材料为15~45份，所述异氰酸酯类交联剂为4~10份。
高阻隔聚脂薄膜的生产方法，所述聚脂薄膜在纵向拉伸与横向拉伸之间增加有涂布工序，所述涂布工序将权1~权4所述任一项涂布层材料涂布在薄膜表面。
对比现有技术，本申请的有益效果在于：
对薄膜包装的阻隔性要求越来越高，传统的镀铝聚脂薄膜只能通过增加镀铝层厚度来增加阻隔性，但镀铝层厚度增加会影响到聚脂薄膜本身的光学、力学性能。本申请在聚脂薄膜的薄膜基层与镀铝层之间增设涂布层，在镀铝层厚度不变的情况下，聚脂薄膜的阻隔性显著增长，且涂布层厚度薄，不会对薄膜的光学、力学性能造成不良影响。
