Description

一种防伪票证热敏纸及其制备方法
技术领域
本发明涉及热敏纸防伪技术领域，特别是涉及一种适用于门票、牌照、发票以及特殊标签领域的防伪票证热敏纸。
背景技术
热敏纸被当做一种可读性信息记录材料，被广泛应用于物流标签、彩票、收银、ATM等领域。在应用效果上，市场上的热敏纸是显黑色文字或图案，是通过热打印等元件发热使得热敏纸涂层中的显色剂和无色染料发生化学反应而显色，从而具备记载信息功能。
随着热敏纸应用领域的延伸，热敏纸已延伸至门票、牌照、发票以及特殊标签等领域使用，因其使用具备一定经济使用价值，市场上希望这类热敏纸具备专一性而不被假冒分子仿造。目前，市场上的热敏纸不具备防伪功能，造假分子很容易买到热敏纸进行电脑设计文字图案打印出门票、牌照甚至发票，给商家带来一定经济损失。为了满足这以特殊领域需要，本发明公开了一种防伪票证热敏纸，特别是涉及一种适用于门票、牌照、发票以及特殊标签领域的防伪票证热敏纸，通过发色装置显色后具备内黑边红的显色防伪功能，如附图中4和5所示，显色大块区域呈现黑色文字图案，在黑色文字图案边缘呈现红色。从而提供一种在具备大众防伪且易辨别的票证热敏纸，在特殊领域上可以打击热敏纸的造假行为。
发明内容
本发明旨在在一定程度上解决上述热敏纸不具备防伪鉴别的缺陷。
本发明的目的是提供一种具有鉴别简单、大众识别的防伪票证热敏纸，克服现有热敏纸通过热打印显色后不具备可辨识性的缺陷的热敏纸。采用本发明所述的技术制备的防伪票证热敏纸不依赖外加特定条件和特种工具，只需通过生活中使用的热敏打印机（包括热打印元件装置和加热），在显色大块区域就会呈现黑色文字图案，在黑色文字图案边缘呈现红色的防伪特征，从而达到鉴别简单、大众识别的防伪目的。
本发明解决以上技术的缺陷所采用的技术方案是：一种防伪票证热敏纸，包括原纸层、预涂层和显色层，所述显色层由显色剂、无色染料、防伪涂料及辅助涂料组成，其中显色剂、无色染料、防伪涂料及辅助涂料按质量份计分别为10-20份、20-30份、1-5份、20-45份；
所述防伪涂料包括发色材料、聚乙烯醇、硅酸盐组成，其中发色材料、聚乙烯醇、硅酸盐按质量份计分别为70-80份、5-10份、5-10份；所述发色材料选自2-甲基-6-(N-乙基-N-4-甲苯基胺)荧烷、1,2-苯并-6-(N-乙基-N-异戊基胺）荧烷中一种。
所述显色剂、无色染料和防伪涂料是在热打印条件下呈现不同颜色，其中无色染料选自2-苯氨基-3-甲基-6-二丁氨基荧烷、3-（N-乙基-异戊氨基）-6-甲基-7-苯胺基荧烷、3-（N-乙基-4-甲苯胺基）-6-甲基-7-苯胺基荧烷、2-(2',4'-二甲基苯氨基-3-甲基-6-二乙氨基荧烷中一种或二种以上的组合。
以上实施中，显色剂为目前热敏纸常用的显色剂，如2,2-双(4-羟苯基)丙烷、4-羟基-4'-异丙氧基二苯砜、4,4'-磺酰基双[2-(2-丙烯基)]苯酚、或4-羟基-4'-苄氧基二苯砜等，显色剂是热敏纸显色化学反应的主要原材料之一。
所述辅助材料包括轻质碳酸钙、二氧化硅、硬脂酸锌、1,2-二苯氧基乙烷、丙烯酸胶乳、乙二醛、丁苯胶乳,按质量份计分别为2-5份、2-5份、2-8份、5-10份、5-10份、2-5份、2-5份。
本发明所述的防伪票证热敏纸在制备工艺与现有热敏纸生产工艺区别在于防伪涂料的制备，依次包括以下步骤： a、按质量份计分别将70-80份、5-10份、5-10份的发色材料、聚乙烯醇和硅酸盐混合均匀制得防伪涂料研磨液；b、通过研磨机将涂料粒径控制在0.2-1.0um范围内；c、将防伪涂料研磨液与显色剂、无色染料和辅助涂料按质量份计分别为1-5份、10-20份、20-30份、20-45份进行搅拌混合。
本发明的原理在于：本发明提供的热敏纸，其显色层在热打印等发热元件作用下，显色剂在与无色染料发生化学反应显黑色字体的同时，显色剂还与防伪涂料发生化学反应显现红色，因两种化学反应能级的差异，当显黑色和显红色化学反应在同一能级下进行时，显黑色部分覆盖了显红色部分就会出现显色大块区域呈现黑色文字图案，视觉上和市场上热敏纸显色一样，无明显差异；而显红色化学反应能在热打印等元件通过打印区域所接触的涂料热传递作用下，围绕显黑色文字图案边缘发生显红色的化学反应，在黑色文字图案边缘呈现红色的特征。
本发明的有益效果是：本发明的防伪票证热敏纸的制备方法简便灵活，易于生产控制；不依赖外加特定条件和特种工具，只需通过生活中使用的热敏打印机（包括热打印元件装置和加热），就会出现如图1中4和5所示显色大块区域呈现黑色文字图案，在黑色文字图案边缘呈现红色的防伪特征，从而达到鉴别简单、大众识别的防伪目的。
附图说明
图1为本发明的结构示意图。
其中：1、原纸层，2、 预涂层，3、 显色层，4、 显红色区域，5 、显黑色区域，6 、打印头等发热元件。
具体实施方式
下面结合附图和具体实施例，对本发明做进一步详细说明。实施例仅供进一步理解本发明，不用来限定本发明的范围。
实施例1
如图1所示，防伪票证热敏纸由原纸层1、预涂层2和显色层3组成。
原纸层和预涂层的生产工艺为现有工艺，由煅烧高岭土、碳酸钙、聚苯乙烯空心球树脂、硬脂酸钙、聚乙烯醇、淀粉胶乳、助剂组成的预涂层涂料，采取刮刀涂布或帘式涂布方式均匀涂布于热敏原纸上，通过干燥和压光形成热敏预涂纸。
显色层由显色剂、无色染料、防伪涂料及辅助涂料组成。取2-甲基-6-(N-乙基-N-4-甲苯基胺)荧烷80kg、聚乙烯醇10kg、硅酸钙10kg混合均匀；通过研磨机将涂料粒径控制为0.5um；取研磨好的防伪涂料5kg、4-羟基-4'-异丙氧基二苯砜20kg、2-苯氨基-3-甲基-6-二丁氨基荧烷30kg、轻质碳酸钙5kg、二氧化硅5kg、硬脂酸锌8kg、1,2-二苯氧基乙烷10kg、丙烯酸胶乳10kg、乙二醛2kg、丁苯胶乳5kg充分混合搅拌。采取刮刀涂布或帘式涂布方式均匀涂布于热敏预涂层上，涂布量为4～8g/m2,通过干燥和压光形成防伪票证热敏纸。
在热打印头等发热元件作用下，显色剂在与无色染料发生化学反应显黑色字体的同时，显色剂还与防伪涂料发生化学反应显现红色，因两种化学反应能级的差异，当显黑色和显红色化学反应在同一能级下进行时，显黑色部分覆盖了显红色部分就会出现如图1中5所示显色大块区域呈现黑色文字图案，视觉上和市场上热敏纸显色一样，无明显差异；而显红色化学反应能在热打印等元件通过打印区域所接触的涂料热传递作用下，围绕显黑色文字图案边缘发生显红色的化学反应，如图1中4所示在黑色文字图案边缘呈现红色的特征。
实施例2
在实施例1的基础上，显色剂更换为4,4'-磺酰基双[2-(2-丙烯基)]苯酚，无色染料更换为2-(2',4'-二甲基苯氨基-3-甲基-6-二乙氨基荧烷，防伪涂料中的发色材料更换为1,2-苯并-6-(N-乙基-N-异戊基胺）荧烷，其余同实施例1所述步骤进行。
以上实施例生产的防伪票证热敏纸，均可达到预期的防伪效果。且目的在于使本领域专业技术人员可以据其了解本发明的技术方案加以实施，不能以其限制本专利的保护范围，本发明的保护范围以权利要求书披露的内容为准。
