一种双组分水分散共聚物乳液、制备方法及其在不干胶标签 面材方面的应用
技术领域
本发明涉及一种共聚物乳液，特别涉及一种双组分水分散共聚物乳液、制备方法及其在不干胶标签面材方面的应用。
背景技术
利用紫外光辐射固化技术生产的油墨，简称UⅤ油墨，具有不含挥发性有机物(VOC)、对环境污染小、固化速率快、节省能源、适宜于高速自动化印刷生产等优点。因而，已被大量应用于纸类不干胶标签的印刷制作。但是由于技术原因，目前市场上大多数的中、低瑞UV油墨印刷在界面自由能较低的薄膜类不干胶材料上(如PE、PP、PVC等)，由于粘附力不高，印刷层容易脱落。
发明内容
本发明的目的在于提供一种双组分水分散共聚物乳液，该乳液可用于制备适用于UV油墨印刷的不干胶标签面材。
本发明还提供一种适用于UV油墨印刷的不干胶标签面材，应用该面材解决了UⅤ油墨印刷在膜质基材上易碎性、粘附力、固化性等方面存在的问题，并使该标签具有优良的耐溶剂擦洗性能。
本发明解决其技术问题所采用的技术方案是：
一种双组分水分散共聚物乳液，该乳液是由组分A和组分B按重量混合而成：

对比例2
不干胶标签面材，包括基材和底涂层。底涂层采用市售溶剂型树脂胶进行涂布，具体方法同实施例7。
性能测试试验
检测方法：
1、机械稳定性：在1000mL搪瓷杯中加入200g用120目筛网过滤后的乳液，将搪瓷杯固定在搅拌机上，以1500r/min转速搅拌10min后观察乳液是否被破乳或絮凝，如无明显的絮凝物，再用120目筛网过滤，如没有或仅有少量絮凝即认为通过。
2、涂膜附着力：按照GB/T 1720-1979《漆膜附着力测定法》标准进行测定。
3、乳液涂膜与CPP薄膜的抗剥离性：采用标准压敏胶带与制备好的预涂膜进行贴合，用压滚沿同一方向滚压数次，然后裁剪成200mm*50mm的试样，在PT1070拉力机上以600mm/min的速率进行剥离，观察被剥离后压敏胶带上的粘附现象，涂层没有任何带起、脱落，预涂膜表面完整，实为合格。
4、UV油墨印刷层与预涂膜的抗剥离性：用标准压敏胶带贴于印刷层表面，用压辊压实后，放置10s，90°瞬间拉起，无掉墨现象视为合格。
5、涂膜耐酒精擦洗性：用二层棉纱布裹在500g砝码上，用95％医用酒精滴在棉纱布上，以不流出酒精为宜，以2s/来回一次的速率在600mm长度范围内来回擦拭，记录涂膜出现破坏时的次数，大于30次即为合格。
使用不干胶标签面材①②③④⑤⑥以及对比例1、2制得的不干胶标签面材分别制作UV油墨印刷的不干胶标签制品，对制备的不干胶标签制品进行性能检测，测试粘附性等性能，结果见表4。
表4
Figure BDA0002673728770000071
Figure BDA0002673728770000081
表4数据证明，本发明提供的乳液具有较好的粘结性能，实现了标签油墨印刷牢度的提高，并且本发明的乳液相比对比例1的聚氨酯乳液具有价格低、环保的优势，而对比例2的溶剂型树脂乳液不够环保，性能也不如本发明的乳液。从表4数据也可以看出，实施例4的配方，相比于其他实施例，粘结性好，附着力强，耐酒精擦洗次数较多，是最佳配比。
以上所述的实施例只是本发明的一种较佳的方案，并非对本发明作任何形式上的限制，在不超出权利要求所记载的技术方案的前提下还有其它的变体及改型。

2.根据权利要求1所述的双组分水分散共聚物乳液，其特征在于：所述其它助剂包括：消泡剂、分散剂、润湿剂、增稠剂、流平剂或pH调节剂中的一种或几种。
3.一种权利要求1所述的双组分水分散共聚物乳液的制备方法，其特征在于：组分A采用半连续预乳化种子乳液聚合方法进行制备：
S1、按配方量在乳化釜内加入乳化剂、部分去离子水、部分共聚单体，搅拌30-40min，得到预乳液，备用；剩余量的共聚单体充分混合后得到混合共聚单体，备用；
S2、在反应釜内加入剩余量的去离子水，升温至70～75℃，加入预乳液的10～12wt%和部分催化剂，升温至82～85℃进行反应；
S3、待混合乳液出现蓝相后，2～3h内连续滴加剩余量的预乳液、混合共聚单体及催化剂，滴毕，保温1～1.5h，然后降温至室温，添加其它助剂后过滤出料，得到组分A。
4.一种适用于UV油墨印刷的不干胶标签面材，包括基材，其特征在于：所述基材表面设有由权利要求1所述的双组分水分散共聚物乳液涂覆而成的底涂层。
5.根据权利要求4所述的不干胶标签面材，其特征在于：所述基材选自聚乙烯膜、聚丙烯膜、聚氯乙烯膜、聚酯膜或合成纸中的一种。
6.一种不干胶标签面材的制备方法，其特征在于该方法包括如下步骤：
①底涂层料液配制：把权利要求1所述的双组分水分散共聚物乳液的组分A按配方量加入组分B，充分搅拌均匀，调整粘度在50～200mPa·s；
②微凹版辊涂布：采用微凹版辊涂布技术将制得的底涂层料液涂布在薄膜基材上，干燥后收卷得到产品；
所述微凹辊直径为50～60mm，湿量涂布厚度为3～20μm，干燥时的烘道温度控制在30～80℃。
7. 根据权利要求6所述的不干胶标签面材的制备方法，其特征在于：涂布采用的涂布机内装有薄膜表面处理电晕装置，薄膜涂布面处理后表面张力≥38 mN/m。
