Description

隔紫外线防蓝光涂液、玻璃及夹层玻璃
本申请要求于2020年12月15日提交中国专利局、申请号为202011469860.1、申请名称为“隔紫外线防蓝光涂液、玻璃及其制造方法”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及表面涂层涂覆技术领域，特别是涂覆在玻璃表面上的功能涂层，具体地提供一种隔紫外线防蓝光涂液、隔紫外线防蓝光玻璃及夹层玻璃，同时还提供一种能够调光或发光的隔紫外线防蓝光夹层玻璃。
背景技术
通过表面涂层涂覆技术可以在基材表面形成功能涂层，以满足隔红外线、隔紫外线、疏水疏油、防雾等要求，其中隔紫外线涂层能够大幅降低紫外线的透过率，从而减少紫外线对人体健康产生的危害以及防止汽车内饰和房屋内饰在短期内老化、褪色。在玻璃基板的表面上形成隔紫外线涂层已经是比较成熟的技术，例如日本专利JP2009184882A、JP2013189345A以及中国专利CN102892851A、CN103347833A、CN111819160A等均公开了在玻璃基板表面通过涂覆隔紫外线涂液形成隔紫外线涂层，具备较好的紫外线屏蔽能力以及较高的硬度和耐磨耗性等机械耐久性。
在可见光光谱中，通常将波长范围为400nm～500nm的光定义为蓝光，其中400nm～420nm的短波蓝光具有较高的能量，会对视网膜产生危害，例如引起视觉疲劳、眩光、视网膜黄斑病变等，因此还需要降低短波蓝光的透过率。中国专利CN109455945A公开了一种反射型防蓝光玻璃及其制备方法，包括玻璃基材和防蓝光涂层，所述的防蓝光涂层是具有反射功能的涂布液，在400-450nm处的蓝光反射率为50％，主要应用在电子产品上，其耐磨性结果不能满足汽车玻璃上的表面涂层的性能要求。
此外，中国专利CN111201457A公开了一种玻璃结构体，其具备一对玻璃板、配置在所述一对玻璃板之间的调光体以及配置在所述调光体与一块玻璃板之间的紫外线吸收层，所述紫外线吸收层在370nm以上且400nm以下的波长区域中的最大透射率为10％以下，在大于400nm且420nm以下的波长区域中的最大透射率为50％以上，如果大于400nm且420nm以下的最大透射率低于50％，则当照射太阳光时玻璃结构体看似被着色。

Figure PCTCN2021137433-appb-000001
从表1中可以看出：
对比例1在弯曲玻璃板上形成硅溶胶涂层，虽然其耐老化性和耐磨耗性符合要求，但是不具有隔紫外线和防蓝光性能；
对比例2在弯曲玻璃板上形成隔紫外线防蓝光涂层，但是在每份硅溶胶中添加了过多(例如30％)的螯合剂，虽然其紫外线透过率、蓝光最大透过率能够满足要求且非常低，但耐磨耗性不能满足要求，无法用作汽车玻璃；
实施例1～3在弯曲玻璃板上形成隔紫外线防蓝光涂层，通过在每份硅溶胶中添加适量的螯合剂，不仅使紫外线透过率、蓝光最大透过率、可见光透过率满足要求，而且使耐老化性和耐磨性均满足要求；
实施例4～5在弯曲玻璃板上形成隔紫外线防蓝光涂层，通过在每份硅溶胶中添加适量的螯合剂，与实施例1～3不同的是螯合剂的添加量更多，紫外线透过率满足要求，耐老化性和耐磨性也均满足要求，蓝光最大透过率比实施例1～3的更低，但可见光透过率低于70％，可以应用在汽车上对可见光透过率不做要求或者要求可见光透过率低于70％的部位，例如用作天窗玻璃，特别是无遮阳帘的天窗玻璃、调光天窗玻璃、发光天窗玻璃等。
以上内容对本发明所述的隔紫外线防蓝光涂液、玻璃及其制造方法以及一种能够调光或发光的隔紫外线防蓝光夹层玻璃进行了具体描述，但是本发明不受以上描述的具体实施方式内容的局限，所以凡依据本发明的技术要点进行的任何改进、等同修改和替换等，均属于本发明保护的范围。
