Abstract

本发明涉及一种变色液晶标签，它由保护膜、基材等组成。在保护膜和基材之间粘合感温变色液晶，用人体温度触摸变色液晶标签后发生颜色变化，即可判别商品的真伪和防止商品被假冒，因此使用方便，并且使用寿命最长。

Description

一种变色液晶标签
技术领域
本发明是涉及一种标签，尤其涉及一种变色液晶标签。
背景技术
现有的商品标签或商标，有二种制作型式，一种是用印刷方法把商标或标签的图案，文字印制在纸质、塑料和金属膜上，然后粘贴在商品或包装物上作标识使用；一种是用变色颜料制作成复合标签或商标，粘贴在商品或包装物上，作标识使用，并通过颜色变化来判别商品的真伪。前者容易伪造，后者颜料有效期短，变色温度高，使用不便。
发明内容
本发明的目的是提供一种变色液晶标签，该标签克服现有技术的不足。
本发明是这样来实现的：变色液晶标签由保护膜，基材等组成，在保护膜和基材之间粘合感温变色液晶。
本发明由于采用了感温变色液晶，比已有的变色颜料标签变色次数显著增加，从原来的200次上升到1 万次左右，延长了寿命。同时选用37℃ 以下变色温度的液晶，用人手触摸标签即能判别商品真伪，因此使用方便，而变色颜料需70℃上温度才能改变颜色；其次当温度超过变色温度100℃时，变色液晶分子排列不被破坏，而变色颜料超过变色温度30℃时，结构即被破坏而失效。
附图说明
图1本发明的结构示意图。
其中：1、保护膜，2、感温变色液晶，3、基材。
具体实施方式
下面结合附图对本发明作进一步的叙述。
一种变色液晶标签，如图1所示，保护膜1是由高分子透明薄膜组成，厚为0.015-0.1mm左右，基材3可采用纸、塑料或金属膜材料，以黑色为佳，增强显色对比度，基材厚度一般为0.03-0.2mm ，感温变色液晶2 采用向列相液晶和胆甾相液晶的混合液晶。前者显色速度快，寿命侯，但成本离，后者色影鲜艳，价格便宜，但耐久性差，二者混合降低成本，改善佳能，达到显著的温度效应和光学特性，液晶膜的厚度通常为0.05mm左右，放置在保护膜1和基材3之间，混合液晶随人体接触变色液晶标签时的温度梯度依次呈现红-黄-绿-兰-紫色，当人体不再接触时，变色液晶标签恢复原状。保护膜与基材3之间选用粘合剂，在常温下用2-5kgf/cm2压力压合固化。两者的外形相同，它的形状可根据商品或包装街的形状、尺寸专门设计。印刷的图案、文字由商品制造者给定。
采用这种结构的变色液晶，解决了商品流转周期过长时，变色颜料失效问题，用人体温度即能判别商品真伪，同时也为商品创造者提供了一种保护商品的防护手段。
