Description

可逆变色涂层组合物及其制备方法
技术领域
本发明涉及可逆变色涂层组合物及其制备方法。
背景技术
热变色颜料可用作可逆低温热变色油漆,其中在50至70℃的温度下变色。一个原理是微胶囊内的物质随温度升高而分散且变透明,并且随温度降低而聚集恢复其原始颜色,然而,高温范围加热产品或高频加热的使用受限,因为当将胶囊加热至300℃或更高时胶囊被破坏且产生气体。另外,红色、黄色和橙色的颜料,其都由镉组成,具有在150至200℃下颜色改变成黑色的性质,蒸煮容器内部的使用由于重金属的毒性而受限。
同时,韩国专利申请公开号10-2012-0052326公开了一种由有机氮硫化合物和水性树脂制成的可逆热变色水溶性油墨组合物,其中有机氮硫化合物为至少一类选自下述的化合物:2-(4-噻唑基)-苯并咪唑、2-(硫氰酸酯甲基硫代)-1,3-苯并噻唑、2-甲基-4-异噻唑啉-3-酮和5-氯-2-甲基-4-异-噻唑啉-3-酮。然而,该发明并未公开本发明所述的热敏板。
因此,为了改进现有技术的缺点和问题,本发明人发明了一种可逆热变色陶瓷涂层剂,其中取决于吸收(吸收和辐射等量)近红外区的所有光的温度,并且其具有400℃或更高的耐热性和耐久性。

[实施例2]
当加热时包括可逆热变色陶瓷涂层的板的颜色变化的鉴别
将实施例1中对照例1和2及试验例1至4的板加热至90℃至150℃。如下表2所示,可以看出试验例1至4在一定温度下存在颜色变化,并且在冷却之后颜色可逆地恢复其原始颜色。
表2
[表2]
[实施例3]
根据加入金属颜色变化的温度差异
使用与实施例1的试验例1相同的方法制备涂层剂和板。然而,没有加入银和铜粉(对照例3),并且当加入0.1或10g的银或铜(其具有优良的热导率)时(试验例5和6),可以看出颜色变化的起始温度下降10℃至20℃,如下表3所示。
表3
[表3]
虽然本发明已经描述了特定实施方案,但是对于本领域技术人员显而易见的是在没有背离本发明的范围下可以进行各种变化,并且其组分可以被同等物替代。另外,在没有背离本发明的基本范围下可以进行各种修饰,并且可以根据本发明的教导内容使用具体条件和材料。因此,本发明不限于作为预期实施本发明的最佳实施方式而提出的特定实施方案,并且本发明需要解释为包括在所附权利要求书中定义的所有实施方案。
工业应用
本发明的板具有400℃或更高的耐热性,因此可用于加热非常稳定的产品,并且因为其具有优良的耐磨性、耐化学性和机械性质,所述板的耐久性增加。
