Description

一种PET层压制卡带胶膜
技术领域
本发明涉及带胶膜，特别涉及一种PET层压制卡带胶膜。
背景技术
当前用于制卡行业所用的带胶膜多为PVC材质，但由于PVC含有卤素且不耐高温，在高端领域不能满足要求，出口也受到一定的限制。因此，对不含卤素的其它基材进行了研究开发，例如PETG和PC材质，但还存在耐热性较差的问题，并且性价比不高。双向拉伸的PET不含有卤素，耐高温性能较好，并且性价比较高，能够满足使用要求，但由于PET材质比较致密，对其表面进行粘结比较困难，而在制卡行业中使用的带胶膜，除了要跟UV胶印油墨进行粘结外，还要满足烫金，贴签名条，压花等后续工序的要求。
现有技术中，为了改善PET的粘结性通常可以采用电晕处理，离线涂布预处理底涂等方法。但每一种处理方法都有各自的优点和局限性。
发明内容
本发明通过对从PET薄膜生产过程中使用的母料开始进行配方优化，同时结合PET在线涂布和离线涂布的全过程总体考虑，设计制造出符合高端要求的PET层压制卡带胶膜，充分发挥每一个阶段的优势，制造出高性价比的PET层压制卡带胶膜。
本发明提供的PET层压制卡带胶膜具体由PET基膜层，基膜层上表面的抗静电抗划伤层，基膜层下表面的附着力增强层，和层压胶层组成，(具体结构如图1所示)。
PET母料的配方设计，由于PET的模头结构为ABA三层共挤结构，为了增加薄膜的开口性会在表层添加气相二氧化硅，虽然开口性提高了，但雾度也有所增加，对PET层压制卡带胶膜的清澈度有不利影响。故对ABA三层的PET母料做如下配方设计：
PET膜层为ABA三层共挤结构，
芯层(55μm) 普通PET母料
两面表层(10μm) 普通PET母料93％-97％+抗水解剂0.5％-1％+紫外线吸收剂2％-6％，其中，抗水解剂为聚碳化二亚胺。
附着力增强层的配方设计
选用水性磺化聚酯作为底涂剂的主体树脂，根据相似相溶的原理，可以和PET薄膜表面产生优异的层间附着力，且由于具有和基膜类似的折射率从而减少了彩虹纹的产生。
底涂剂的组成如下：
Figure BDA0002230519140000021
其中，水性交联剂可以是氨基树脂、水性噁唑啉、氮丙啶或聚碳化二亚胺，能够增强耐水性和涂层强度。
底涂剂主体树脂(水性磺化聚酯630(25％))的制备
①水性磺化聚酯630 25份
②乙二醇叔丁醚(ETB) 10份
③去离子水 65份
底涂剂主体树脂中各个组分溶解的顺序为：先往带有冷凝夹套的溶解釜里加入②，③后，在搅拌的状态下加入①，最后升温至90℃左右，一直搅拌直到全部溶解为止，迅速通冷却水降温，出料备用。
抗静电抗划伤层的组成如下：
水性磺化聚酯AA-813(1.5％) 65-80份
水性抗静电剂 20-35份
水性基材润湿剂 0.1-1份
其中，水性抗静电剂为水性聚噻吩或水性碳纳米管，水性基材润湿剂为含氟的基材润湿剂FSO或270。
所述层压胶层为水性聚氨酯胶层，层压胶的组成如下：
Figure BDA0002230519140000031
所述PET层压制卡带胶膜的制备方法为：先采用双向拉伸生产抗水解耐紫外线BOPET基膜，再将薄膜在横拉伸涂布前进行电晕；然后配制附着力增强层和抗静电划伤层的在线涂布胶水，在进入横拉伸之前利用在线涂布机在线涂布附着增强层和抗静电抗划伤层，进行横拉伸，并烘干，最后离线涂布层压胶层，收卷。
本发明制备PET层压制卡带胶膜的具体工艺是：生产抗水解耐紫外线BOPET基膜→配制在线涂布胶水→薄膜在横拉伸涂布前进行电晕→利用在线涂布机涂布→横拉伸段烘干→离线涂布→收卷。
配制在线涂布胶水，控制固含量在10％左右；
电晕后的达因值大于36；
在线涂布机的湿涂布量6μ左右；通过D-BAR类型的在线涂布机两套供料系统分别在膜的两面涂布抗静电抗划伤层和附着力增强层。
横拉伸定型段的温度230℃至245℃之间。
有益效果：
现有技术中，PET带胶膜研发往往从已拉伸制造的基膜开始研究怎么使用适当的胶水来进行研究开发，这样做会导致很难平衡附着力，耐高温高湿和后续制卡工艺的要求。而本发明利用双向拉伸PET薄膜在横拉伸段的高温，使用在线涂布的方法在横拉伸前进行双面在线涂布，一面涂布抗静电抗划伤层，另一面涂布后续层压胶水附着力增强层，由于横拉伸的温度高达230℃至245℃之间，在这温度下PET薄膜处于半熔融状态，可与在线增强涂层充分融合固化，达到超强的附着力。同时因为使用的是横拉伸段的能量，能耗低，减少了离线涂布过程反复收放卷带来的低效率和涂布良率的下降。

再将层压胶胶水用精密微凹涂布生产线涂布在涂布了底涂剂和抗静电抗划伤底涂剂的PET膜上，网纹辊目数选用120目，经过温度120℃的烘道中烘干，时间60秒，下线后60℃烘房再熟化24小时，然后冷却至室温进行性能测试。
对比实施例3
抗静电划伤层和层压胶配方同实施例3。
PET带胶膜的具体制备工艺：
首先对PET基膜进行电晕处理，电晕后的达因值大于36，增强附着力；然后配制抗静电划伤层的在线涂布胶水，控制固含量在10％左右；在进入横拉伸之前利用在线涂布机在线涂布抗静电抗划伤层，在线涂布机的湿涂布量6μ左右；进行横拉伸，并烘干，(横拉伸定型段的温度230度至245度之间)
最后离线涂布层压胶层，将水性PET带胶膜胶水用精密微凹涂布生产线涂布在PET在线预涂膜上，网纹辊目数选用120目，经过温度120℃的烘道中烘干，时间60秒，下线后60℃烘房再熟化24小时，然后冷却至室温进行性能测试。
