Description

一种储能型发光粉末涂料涂层及其制备方法 技术领域
本发明涉及粉末涂料领域，尤其涉及一种储能型发光粉末涂料涂层及其制备方法。
背景技术
粉末涂料是一种100％固体组分的涂料，与传统的溶剂型及水性涂料不同，其VOC(挥发性有机化合物)几乎为零，无溶剂污染也更为节能环保，是一种环境友好型的涂料。蓄光型发光涂层因采用特殊的超长余辉发光材料，这种发光材料在光照下吸收光能并储存起来，在光照停止之后以光的形式释放出来，这个过程可以持续几分钟到几十个小时，是一种自主发光功能性发光材料。由于这种独特的性能，储能型发光涂层被广泛应用在景区和办公场所警示牌、建筑装饰、工艺饰品、消防安全、军事设施和航空航天等领域。
传统的储能型发光粉末涂料涂层是将发光粉末涂料直接喷涂在基材上并通过热固化的方式得到。通过这种方式制备的发光粉末涂料涂层其初始发光强度低，降低了长余辉发光材料的利用效率，在发光强度衰减速率相同的情况下这种具有较低初始发光强度的涂层其余辉时间会缩短，难以用于实际应用。

表5-本申请实施例1-9中发光涂层和反光涂层选择和性能试验结果

表6-本申请实施例10-14中发光涂层和反光涂层选择和性能试验结果
表7-本申请对比例1-5中发光涂层的选择和性能试验结果
结合表5中实施例5-6的性能试验结果可知，发光涂层的膜厚越高最终涂层的发光强度也会增强，发光涂层的膜厚的增加有利于初始发光强度和余晖时长的增加。
结合表5中实施例1-5、7-9的性能试验结果可知，发光涂层中发光材料A的含量增加会促进初始发光强度的增大，随着发光涂层中发光材料A含量的增加所得到的发光粉末涂料涂层的初始发光强度逐渐增大；而且，相同发光材料含量的前提下，非包裹型铝酸锶发光材料B相比于包裹型铝酸锶发光材料，涂层最终的初始发光强度及余晖时长均显著提高。
结合表5-7中实施例13-14和对比例3、5的性能试验结果可知，在发光涂层中添加钛白粉或钛黄颜填料均会产生负面影响，导致涂层的发光强度和余晖时长减少。
结合表5、7中实施例1-4和对比例1-4的性能试验结果可知，通过设置反光涂层，可以显著增强涂层整体的发光强度，同时对比实施例7-9、10-12的结果可知，低光泽度的反光涂层对涂层整体的发光强度和余晖时长增加效果较佳。
以上所述的具体实施例，对本发明的目的、技术方案和有益效果进行了进 一步的详细说明，应当理解，以上所述仅为本发明的具体实施例而已，并不用于限定本发明的保护范围。特别指出，对于本领域技术人员来说，凡在本发明的精神和原则之内，所做的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
