Description
本发明涉及包装材料技术领域，特别是涉及一种深纹路图案转移膜、转移材料及其制备方法。
现有的普通热压转移膜涂层薄，仅能实现低于1um的浅纹路图案转印。若要实现较高的防伪度及表现力，需要制备深纹路图案的材料，深纹路图案的材料多为复合材料，即材料表面还存有薄膜，不利于包装材料的降解，因此需要深纹路图案转移材料，也称为深纹路图案转移材料，该材料将深纹路图案涂层转移至基底层之后剥离基膜，有利于环保。
深纹路图案转移材料UV全息层采用UV树脂涂层，通过镍板模具将深纹路微纳结构压印复制在UV树脂涂层上。目前UV树脂涂层制备深纹路图案转移材料的问题是：在UV树脂涂层上用镍板模具压印深纹路结构时，UV树脂涂层与镍板之间的粘接力大于基膜与UV树脂涂层的粘接力，UV树脂涂层与镍板模具互粘，难以剥离，制作困难；若为了便于镍板模具脱离，增加基膜与UV树脂涂层的粘接力，又会导致将树脂涂层转移至衬底时基膜剥离困难。
本发明的目的在于提供一种深纹路图案转移膜、转移材料及其制备方法，基膜剥离容易，且操作简单。
本发明提供一种深纹路图案转移膜，包括基膜、UV树脂涂层及位于所述基膜与UV树脂涂层之间的化学层，所述化学层材料为水性聚氨酯体系、水性聚酯体系、水性环氧体系以及水性丙烯酸体系的一种或多种，所述UV树脂涂层厚度为1~50um，是所述化学层厚度的5 ~15倍，所述UV树脂涂层采用的UV树脂固化收缩率为1%~10%。
进一步地，所述UV树脂涂层为UV全息层，压印有深纹路微纳结构，所述微纳结构深度小于或等于所述UV树脂涂层厚度。
进一步地，所述UV树脂固化收缩率为1%~5%。
进一步地，所述UV树脂涂层在远离所述化学层的一侧设置有镀层或/和颜色层。
本发明还提供一种如上所述的深纹路图案转移膜的制备方法，其特征在于，包括：S1：在所述基膜上涂布所述化学层；S2：在所述化学层上涂布所述UV树脂涂层；S3：用具有微纳结构的模具将微纳结构压印复制在所述UV树脂涂层上并进行UV固化，得到深纹路图案转移膜。
本发明还提供一种深纹路图案转移材料，包括依序设置的化学层、UV树脂涂层、胶层及基底层，所述化学层材料为水性聚氨酯体系、水性聚酯体系、水性环氧体系以及水性丙烯酸体系的一种或多种，所述UV树脂涂层厚度为1~50um，是所述化学层厚度的5 ~15倍，所述UV树脂涂层采用的UV树脂固化收缩率为1%~10%。
进一步地，所述UV树脂涂层为UV全息层，压印有深纹路微纳结构，所述微纳结构深度小于或等于所述UV树脂涂层厚度。
进一步地，所述UV树脂固化收缩率为1%~5%。
进一步地，所述UV树脂涂层在远离所述化学层的一侧设置有镀层或/和颜色层。
本发明还提供一种如上所述的深纹路图案转移材料的制备方法，其特征在于，包括：S1：在所述基膜上涂布所述化学层；S2：在所述化学层上涂布所述UV树脂涂层；S3：用具有微纳结构的模具将微纳结构压印复制在所述UV树脂涂层上并进行UV固化，得到转移膜；S4：将所述转移膜通过胶水与基底进行复合，形成胶层与基底层；S5：剥离所述基膜，得到深纹路图案光学转移材料。
本发明提供的深纹路图案转移膜、转移材料及其制备方法，充分利用了UV树脂涂层的固化特性，巧妙设置化学层，且通过调节化学层厚度及UV树脂涂层厚度和固化收缩率来控制UV树脂涂层与镍板及基膜的粘接力，解决了UV树脂涂层与基膜及模具之间粘接力大小的问题，并且操作简单，工序简便成本低，制得的深纹路图案转移材料微纳结构深度大，具有极强的表现力和防伪度，转移至基底后基膜可剥离循环利用，转移材料表面无基膜，环保易降解。
图1为本发明第一实施例深纹路图案转移膜镀铝前的示意图。
图2为图1所示深纹路图案转移膜镀铝后的示意图。
图3为本发明第一实施例深纹路图案转移材料的示意图。
图4为本发明第二实施例深纹路图案转移材料的示意图。
下面结合附图和实施例，对本发明的具体实施方式作进一步详细描述。以下实施例用于说明本发明，但不用来限制本发明的范围。
实施例一
如图1所示，本实施例中，一种深纹路图案转移膜，依次包括基膜1、化学层2、UV树脂涂层3。
基膜为PET材质，厚度为18um。化学层2采用水性聚酯体系，通过卷对卷涂布在基膜1表面。化学层2厚度为0.8um。在化学层2上涂布UV树脂涂层3，UV树脂涂层3采用的UV树脂固化收缩率为3%，树脂涂层厚度为8um。
通过镍板模具将全息微纳结构压印复制在UV树脂涂层上并进行UV固化，得到深纹路图案转移膜。UV树脂涂层3形成UV全息层，微纳结构深度为5~6um，可实现不同深纹路图案的优异表现力和防伪度。在其它实施例中，也可以不通过镍板模具将全息微纳结构压印复制在UV树脂涂层上形成UV全息层，而是通过其它方式得到UV树脂涂层的深纹路图案。
化学层2可增强基膜1与UV树脂涂层3的结合牢度，使得基膜1与化学层2及UV树脂涂层3的粘接牢度大于UV树脂涂层3与镍板模具的粘接牢度，从而保证顺利地和镍板模具剥离。经过UV固化，固化过程中UV树脂产生化学交联，体积收缩，产生收缩应力，与之相邻的化学层2随之一起收缩，但是基膜1不产生收缩，由此化学层2与基膜1粘接牢度下降，如此化学层2与UV树脂涂层3的结合牢度大于与基膜1粘接牢度，以便后续基膜1在涂层转移后可以顺利与化学层2剥离。
在所述UV树脂涂层3具有微纳结构的一表面仿形进行真空镀铝，铝层厚度为30~40nm，得到具有镀层4（镀层还可以为介质层或其它金属层，例如硫化锌）的转移膜（如图2所示）。
在镀层4表面涂布复合胶并与纸张基底（基底还可以为玻璃、皮革、织物等）复合，形成胶层5与基底层6；剥离表面的基膜1，得到深纹路图案转移材料（如图3所示），可广泛应用于各种包装、装饰领域。
实施例二：如图4所示，一种深纹路图案转移材料，依次包括化学层2’、UV树脂涂层3’、颜色层7’、胶层5’以及基底层6’。化学层2’采用水性聚氨酯体系，厚度为3um。UV树脂涂层3’的UV树脂固化收缩率为5%，涂层厚度为20um。微纳结构深度为10um，可实现更强的表现力和防伪度。在所述UV树脂涂层3’具有微纳结构的一表面涂布颜色层7’，例如黑色、蓝色等，颜色油墨为纳米级，颜色油墨填充在微纳结构中。在颜色层7’表面涂布复合胶并与皮革基底复合，形成胶层5’与基底层6’，得到深纹路图案转移材料，可广泛应用于各种衣服、鞋、包等装饰上。未特别指出的结构形状、材料、加工方法等均可与实施例一相同，在此就不再重复。
以上所述，仅为本发明的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本发明的保护范围之内。因此，本发明的保护范围应以所述权利要求的保护范围为准。
