Description

一种预涂膜
技术领域
本发明涉及高分子材料技术领域，具体涉及一种预涂膜。
背景技术
覆膜属于印后加工的一种主要工艺，是将涂布黏合剂后的塑料薄膜，与纸质印刷品经加热、加压后黏合在一起，形成纸塑合一的产品，它是目前常见的纸质印刷品印后加工工艺之一。经过覆膜的印刷品，由于表面多了一层薄而透明的塑料薄膜，表面更加平滑光亮，不但提高了印刷品的光泽度和牢度，延长了印刷品的使用寿命，同时塑料薄膜又起到防潮、防水、防污、耐磨、耐折、耐化学腐蚀等保护作用。如果采用透明亮光薄膜覆膜，覆膜产品的印刷图文颜色更鲜艳，富有立体感，特别适合绿色食品等商品的包装，能够引起人们的食欲和消费欲望。如果采用亚光薄膜覆膜，覆膜产品会给消费者带来一种高贵、典雅的感觉。因此，覆膜后的包装印刷品能显著提高商品包装的档次和附加值。覆膜工艺是20世纪80年代后期引入我国的，由于覆膜工艺不仅可以对印刷品提供保护作用，延长其使用寿命，同时可以提高印刷品的外观效果，该工艺已迅速在全国得到普及，广泛的应用于书刊、食品、烟酒、药品等包装上。
预涂膜是指预先将塑料薄膜上胶、复卷后，再与纸张印品复合的工艺。它先由预涂膜加工厂根据使用规格、幅面，将胶液涂布在薄膜上复卷后供使用厂家选择，而后再与印刷品进行复合。预涂膜可以应用于很多领域，如印刷、包装领域。经覆膜的印刷品，由于表面多了一层薄而透明的塑料薄膜，表面更平滑光亮，从而提高印刷品的光泽度和牢度，图文颜色更鲜艳，富有立体感，同时更起到防水、防污、耐磨、耐摺、耐化学腐蚀等作用。
目前的预涂膜不易与热熔胶结合，覆膜后热熔胶热熔温度过高，热熔固化不均匀，导致印刷品与预涂膜的结合牢度不够，时间久了预涂膜容易与被覆膜物品脱落，造成了许多产品上的缺陷。
发明内容
本发明的目的是为了解决上述问题，提供一种预涂膜。
为了达到上述发明目的，本发明采用以下技术方案：
一种预涂膜，包括基材层和热熔胶层，在基材层和热熔胶层之间设有功能层，功能层采用质量分数为3-5%的功能组合物的水溶液涂覆而成，功能组合物按重量份数计包括羧甲基纤维素100份、聚乙烯吡咯烷酮33-35份、柠檬酸钠5-7份、水解聚马来酸酐1-3份和磷酸氢二钠0.5-1份。
本发明在热熔胶层与基材层之间设置一层功能层，通过功能层的作用，增强热熔胶与基材层的牢固度，从而提高热熔层与基材层的结合持久度，提高使用寿命。具体的是采用功能组合物的水溶液在基材层上进行涂覆而成，然后在这个涂覆后的功能层上涂覆热熔胶，这样在功能层的作用下，热熔胶与基材层结合更加牢固。其核心是羧甲基纤维素、聚乙烯吡咯烷酮、柠檬酸钠、水解聚马来酸酐和磷酸氢二钠混合而成，在使用时，用水配置成水溶液。由于各物质都是水溶性的，配置成水溶液后能够更好地均匀涂覆在基材层表面。这几种物质进行配合后，不仅能够与树脂类的几种原料制备成的基材层很好的结合，而且与EVA热熔胶具有非常好的粘结效果。申请通过实验研究发现，在上述配比范围下，能够通过调节各组分之间的配比适应不同原料的基材层，并且与通用型的热熔胶具有很好的粘结效果，特别是EVA型，粘结效果最佳。
作为优选，所述功能组合物按重量份数计包括羧甲基纤维素100份、聚乙烯吡咯烷酮33份、柠檬酸钠5份、水解聚马来酸酐3份和磷酸氢二钠0.5份。
在该配比下，对于不同原料的基材层的综合粘结性能最好，具有最好的普适性。
作为优选，所述功能组合物还包括0.1-0.2的氯化铵。
加入少量氯化铵后，能够平衡各组分之间的兼容性，利于各组分配合后性能的发挥。
作为优选，所述基材层的厚度为0.01-0.03mm。
作为优选，所述基材层为线性低密度聚乙烯、聚丙烯或聚酯。
作为优选，所述热熔胶层包括以下重量份数的组分：乙烯-醋酸乙烯共聚物100份、醋酸乙烯-氯乙烯10-15份、乙基纤维素2-3份、聚乙烯亚胺5-8份、季戊四醇硬脂酸酯1-3份、水性聚氨酯3-5份和端羟丙基含氟聚硅氧烷0.5-1份。
为了配合上述功能层，本发明提供了一种适用于上述功能层的热熔胶，该热熔胶单独实用时，其热熔效果一般，当其与上述
作为优选，所述热熔胶层包括以下重量份数的组分：乙烯-醋酸乙烯共聚物100份、醋酸乙烯-氯乙烯10份、乙基纤维素3份、聚乙烯亚胺5份、季戊四醇硬脂酸酯3份、水性聚氨酯5份和端羟丙基含氟聚硅氧烷0.5份。
本发明制备的预涂膜，其基材层膜与热熔胶有较好的粘结力，在将其在样品上覆膜后使用寿命更持久，耐久力得到很大的提升。热熔胶在固化后固化均匀，对覆膜后的寿命起到了积极作用。同时，本发明提供的热熔胶能够达到更好的粘结效果。
