Description

一种环保涂层纸基射频识别天线及其制造方法 技术领域
本发明涉及一种环保涂层纸基射频识别天线，本发明还涉及一种环保涂层纸基射频识别天线的制造方法。
背景技术
目前普通的射频识别RFID(Radio Frequency Identification的缩写)天线制造因工艺和强度要求，一般用PET等塑料膜作为基材，在基材上用导电材料形成导电图案，或者称为天线，用其他材料作为基材的产品则比较少。
纸基RFID天线具有易碎防伪的优点，且相比PET等塑料膜基材更为环保。目前市面上已经出现了纸基RFID天线，采用的制造方法有以下三种：
1、直接采用导电油墨在纸基材上印刷RFID天线。但该方法因油墨系统复杂、印刷精度不高、墨层厚、成本较高等缺点还未能完全克服，目前还不能满足天线精细印制的要求。
2、采用转移法生产纸基RFID天线。该方法是先在其他基材上制成天线，然后利用基材上的一层可剥离膜将天线整体剥离后转移到纸质基材上。该方法生产工艺较为复杂，比普通生产流程多了一道转移工序，而且要求基材上有易剥离层，对基材有特殊要求，使成本增加。
3、采用模切法生产纸基RFID天线。该方法是将纸基和导电金属膜复合后，再用模切的方法模切出需要的天线图案形状。但模切法本身难以满足高精细要求，在实际中也没有被广泛应用。
发明内容
本发明的目的在于提供一种环保涂层纸基射频识别天线及其制造方法，以制备出质量更好的环保涂层纸基射频识别天线。
本发明采用了如下技术方案：

本发明还提供一种制造如权利要求1所述的环保涂层纸基射频识别天线的方法，其特征在于，包括如下步骤：
(1)对基纸层进行表面预处理；
(2)在纸张表面涂布水性UV试剂，形成水性UV涂层；
(3)使用UV固化水性UV涂层，制成具有UV固化涂层的纸基；

进一步，本发明的环保涂层纸基射频识别天线的制造方法，还可以具有这样的特征：其中，步骤一中的表面预处理包括：在基纸层的两个面进行蒸馏水喷雾处理的步骤。
进一步，本发明的环保涂层纸基射频识别天线的制造方法，还可以具有这样的特征：其中，步骤一中的表面预处理包括：在纸基材的两个面进行电晕处理的过程。

在上述方法中，增加纸张表面能的方法也能用双面电晕来替代。采用专用的电晕设备，只是采用电晕的成本相对于喷雾成本更高一些。
水性UV试剂涂布也可以用刮刀涂布、辊式涂布、喷雾涂布等方式来替代。但用浸泡涂布的效果是最好的，并且对设备要求最简单。

<实施例一>
本发明环保涂层纸基射频识别天线具体制造方法步骤如下：
步骤一：以普通纸张为基材，在纸基材的两个面分别进行蒸馏水喷雾处理，使得纸张表面能提高。使用超声波高频震荡，将水雾化。经过喷雾处理后纸张表面能增加，有利于步骤(2)中将水性UV试剂涂层附着到纸基材上。
步骤二：把经过喷雾处理的纸基材用水性UV试剂进行浸泡涂布，形成水性UV涂层。
其中，以质量份计，水性UV试剂的配方及组成如下：
Figure PCTCN2017078512-appb-000003
经过步骤二处理后，纸张具有了耐酸碱、耐溶剂、耐摩擦的能力，表面平整光滑，其强度、耐水性、耐酸碱性可以适应后续覆合、印刷、蚀刻的工序处理而不会遭受破坏。
步骤二中采用的水性UV试剂为环保型试剂。用这种有环保UV涂层纸基材做成的射频识别天线耐弯折性能优良、可靠性能强、产品寿命长，基材容易降解。
步骤二中，聚胺脂树脂的生产厂商及型号为：聚胺脂树脂：美国科聚亚Vibrathene 8585；光敏剂的生产厂商及型号为：巴斯夫Lucirin TPO 75980–60–8；增硬剂的生产厂商及型号为：炜林纳WNA-108；蜡乳剂的生产厂商及型号为：巴斯夫Emulgade 1000NI；水性增稠剂的生产厂商及型号为：诺普科SN-612。
步骤三，把浸泡涂布的纸基经过UV固化，再加热加压。具体而言，使用大于500毫焦的UV能量来固化，再经过80℃的镜面辊温度跟10㎏的压力与UV图层面接触压合。使得涂层跟PET薄膜一样光洁平整。
步骤四，将纸基材跟金属膜进行覆合、印刷、蚀刻、制备射频识别天线。具体步骤如下：
4.1将铝箔与纸基材覆合。铝箔中铝的含量为99.6％wt-99.99％wt，采用氮气保护退火处理，厚度为0.030mm±0.0010mm，表面无油、光滑、无孔，表面粗糙在12度以上。
4.2使用清洗溶液对覆合的铝箔进行表面处理。为了去除铝箔表面的各种油污及氧化膜，以保证印刷质量，本步骤中覆合后的铝箔经过喷淋机进行清洗，覆合铝箔的移动速度为1米/分钟-4米/分钟。清洗溶液采用NaoH溶液，NaoH溶液的浓度为1％-4％，清洗溶液的温度为40℃-50℃。
4.3使用油墨进行印刷；为了适应后续绑定芯片的工艺要求，本步骤中油墨印刷采用凹版印刷；为了降低溶剂挥发对大气严重的污染，采用的油墨经紫外线固化，无溶剂挥发。本实施方式中所采用的油墨，黏度为2000pa/s，酸度PH值为6.7-6.8，与铝表面的亲和角小于20°。 油墨的成分为：紫胶树脂58.4％wt，颜料20％wt，松香2％wt，石蜡3％wt，萜烯树脂1％wt，小分子量树脂11％wt，光敏剂0.4％wt，硅油1％wt，引发剂0.2％wt，气相二氧化硅3％wt。
4.4对覆合合成铝箔进行化学蚀刻；采用浓度为20％wt-25％wt的浓盐酸进行化学蚀刻。
4.5去除蚀刻后铝天线表面的油墨。采用浓度为1％wt-4％wt的碱性溶液去除蚀刻后铝天线表面的油墨。制成环保涂层纸基射频识别天线：其结构是：从中间向两侧设置的基纸层，UV固化层和射频识别天线层。
对于高频射频识别天线，因为需要在双面蚀刻天线图案，所以在后续与金属膜复合时可进行双面覆合，形成“金属膜-纸基-金属膜”的复合结构。对于超高频射频识别天线，因为只需要在单面蚀刻天线图案，所以在后续与金属膜复合时进行单面覆合，形成“金属膜-纸基”的复合结构。
<实施例二>
步骤一：以普通纸张为基材，在纸基材的两个面分别进行蒸馏水喷雾处理，使得纸张表面能提高。使用超声波高频震荡，将水雾化。经过喷雾处理后纸张表面能增加，有利于步骤(2)中将水性UV试剂涂层附着到纸基材上。
步骤二：把经过喷雾处理的纸基材用水性UV试剂进行浸泡涂布，形成水性UV涂层。

经过步骤二处理后，纸张具有了耐酸碱、耐溶剂、耐摩擦的能力，表面平整光滑，其强度、耐水性、耐酸碱性可以适应后续覆合、印刷、蚀刻的工序处理而不会遭受破坏。
步骤二中采用的水性UV试剂为环保型试剂。用这种有环保UV涂层纸基材做成的射频识别天线耐弯折性能优良、可靠性能强、产品寿命长，基材容易降解。
步骤二中，聚胺脂树脂的生产厂商及型号为：聚胺脂树脂：美国科聚亚Vibrathene 8585；光敏剂的生产厂商及型号为：巴斯夫Lucirin TPO 75980–60–8；增硬剂的生产厂商及型号为：炜林纳WNA-108；蜡乳剂的生产厂商及型号为：巴斯夫Emulgade 1000NI；水性增稠剂的生产厂商及型号为：诺普科SN-612。
步骤三，把浸泡涂布的纸基经过UV固化，再加热加压。具体而言，使用大于500毫焦的UV能量来固化，再经过80℃的镜面辊温度跟10㎏的压力与UV图层面接触压合。使得涂层跟PET薄膜一样光洁平整。
步骤四，将纸基材跟金属膜进行覆合、印刷、蚀刻、制备射频识别天线。具体步骤如下：
4.1将铝箔与纸基材覆合。铝箔中铝的含量为99.6％wt-99.99％wt， 采用氮气保护退火处理，厚度为0.030mm±0.0010mm，表面无油、光滑、无孔，表面粗糙在12度以上。
4.2使用清洗溶液对覆合的铝箔进行表面处理。为了去除铝箔表面的各种油污及氧化膜，以保证印刷质量，本步骤中覆合后的铝箔经过喷淋机进行清洗，覆合铝箔的移动速度为1米/分钟-4米/分钟。清洗溶液采用NaoH溶液，NaoH溶液的浓度为1％-4％，清洗溶液的温度为40℃-50℃。
4.3使用油墨进行印刷；为了适应后续绑定芯片的工艺要求，本步骤中油墨印刷采用凹版印刷；为了降低溶剂挥发对大气严重的污染，采用的油墨经紫外线固化，无溶剂挥发。本实施方式中所采用的油墨，黏度为2000pa/s，酸度PH值为6.7-6.8，与铝表面的亲和角小于20°。油墨的成分为：紫胶树脂58.4％wt，颜料20％wt，松香2％wt，石蜡3％wt，萜烯树脂1％wt，小分子量树脂11％wt，光敏剂0.4％wt，硅油1％wt，引发剂0.2％wt，气相二氧化硅3％wt。
4.4对覆合合成铝箔进行化学蚀刻；采用浓度为20％wt-25％wt的浓盐酸进行化学蚀刻。
4.5去除蚀刻后铝天线表面的油墨。采用浓度为1％wt-4％wt的碱性溶液去除蚀刻后铝天线表面的油墨。制成环保涂层纸基射频识别天线：其结构是：从中间向两侧设置的基纸层，UV固化层和射频识别天线层。
对于高频射频识别天线，因为需要在双面蚀刻天线图案，所以在后续与金属膜复合时可进行双面覆合，形成“金属膜-纸基-金属膜”的复合结构。对于超高频射频识别天线，因为只需要在单面蚀刻天线图案， 所以在后续与金属膜复合时进行单面覆合，形成“金属膜-纸基”的复合结构。
<实施例三>
步骤一：以普通纸张为基材，在纸基材的两个面分别进行蒸馏水喷雾处理，使得纸张表面能提高。使用超声波高频震荡，将水雾化。经过喷雾处理后纸张表面能增加，有利于步骤(2)中将水性UV试剂涂层附着到纸基材上。
步骤二：把经过喷雾处理的纸基材用水性UV试剂进行浸泡涂布，形成水性UV涂层。
其中，以重量份计，UV固化层所使用的水性UV涂层的配方包括：

上述各个实施例中采用水性UV试剂的配方，其性能检测的结果如表1所示。表1中同时呈现了其它几种水性UV试剂的性能作为对比。

增加纸张表面能的方法也能用双面电晕来替代，采用专用的电晕设备，只是采用电晕的成本相对于喷雾成本更高一些。
水性UV试剂涂布也可以用刮刀涂布、辊式涂布、喷雾涂布等方式来替代。但用浸泡涂布的效果是最好的，并且对设备要求最简单。
