Description
技术领域
本发明涉及PET薄膜领域，特别是一种PET薄膜的表面处理方法。
背景技术
在包装薄膜的应用中，经常会使用PET镀铝薄膜，而PET镀铝薄膜的常规生产方法是在PET薄膜的表面进行电晕处理后，使用镀铝机在PET薄膜表面镀铝。镀层厚度一般在300--400埃左右。而镀铝后的薄膜，可以增加阻隔性能和装饰性。
传统的PET薄膜的镀铝技术，其镀层容易脱落，而且镀层的厚度越厚，镀铝层越容易脱落。
为了解决上述问题，现在有些国外的厂家会对镀层表面进行特殊处理，如杜邦公司生产的PET薄膜能够有效防止镀膜脱落，但其方法的成本相对较高，给企业带来了较大的成本压力。
因此现在需要一种能够解决上述问题的方法或装置。
发明内容
本发明是为了解决上述技术问题，提出一种PET薄膜的表面处理方法，经过该方法处理后的PET薄膜，能够获得较高强度的镀层，同时即便在高温、高湿环境下，也能够保持较高的镀层强度。
本发明的技术解决方案是：一种PET薄膜的表面处理方法，其特征在于：所述的方法按照以下步骤进行：
首先配制活化溶剂，所述的活化溶剂由甲酰胺和甲基甲酰胺按照9:1的体积比混合获得，然后将配制好的活化溶剂均匀喷涂在PET薄膜表面，然后将PET薄膜置于干燥箱内在100-130℃的条件下进行干燥处理，待完全干燥后对PET薄膜进行电晕处理，然后配制增强溶剂，并将增强溶剂均匀涂布在PET薄膜表面，然后将PET薄膜置于干燥箱内在100-130℃的条件下进行干燥处理，待完全干燥后收卷，
所述的增强溶剂由以下原料按照按照体积比混合而成：
丙烯酸树脂 20-90%，
硅烷偶联剂 0.5-3%，
聚氨酯树脂 10-20%，
其中聚氨酯树脂由丙烯酸酯多元醇制备而成。
所述的处理方法采用分步式方法进行。
所述的方法采用联机一次成型方法进行。
本发明同现有技术相比，具有如下优点：
本种PET薄膜的表面处理方法，通过喷涂活化溶剂、干燥、电晕处理，以及再次涂抹增强溶剂，再次干燥和最后的收卷等步骤，让PET薄膜表面的镀铝层的强度得到提高，经过上述处理的PET薄膜，即便在高温、高湿的环境下，也能够保持相对较高的镀层强度。
具体实施方式
