Description

一种防蓝光胶水组合物及其制备方法
技术领域
本发明涉及一种防蓝光胶水组合物及其制备方法，该组合物可以进一步吸收对人眼有害的380-425nm的高能波长，对无害的其它波长的光线具有高透过率，以减少产品色调变化，保持显示器的高亮度。
背景技术
智能手机时代人们更多的时间花费在盯着手机屏幕上，然而手机屏幕、LED、电脑屏幕灯都会产生大量的蓝光，这样会给人们的眼睛与手带来危害，会激发褐色色素，让皮肤产生黄斑、雀斑，会加深眼睛近视程度，产生视觉疲劳感，同时也不利于正常睡眠。
目前，国内外产品对于有害蓝光的截止波段不统一，有的截止都450nm，有的截止到480nm，还有的截止到500nm。然而，本发明人经过长期的研究发现对人眼真正有害的蓝光波段为400-425nm，因此，无需将425之后的蓝光部分截止，所以，市场上急需一种结构简单，易于制作，又能有效阻隔有害蓝光的防蓝光胶水制品。
本发明提供一种防蓝光胶水组合物及其制备方法，具有抑制蓝光的作用，同时对无害的其它波长的光线具有高透过率，以减少产品色调变化，保持显示器的高亮度。
发明内容
本发明的目的之一在于提出一种防蓝光胶水组合物及其制备方法，该组合物可以进一步吸收380nm-425nm的高能波长，以减少产品色调变化，保持显示器的高亮度，可克服现有技术中的不足。
为实现上述发明目的，本发明采用了如下技术方案：
一种防蓝光胶水组合物，其特征在于，该组合物的组份为：胶水、紫外吸收剂、自由基捕捉剂、抗氧剂、偶氮类颜料。
本发明的另一目的在于提出一种防蓝光胶水组合物的制备方法，其工艺简单，易于规模化生产，且原料廉价易得，设备投资少，成本低廉，该方法为：
将胶水、紫外线吸收剂、自由基捕捉剂、抗氧剂、偶氮染料、溶剂、固化剂等按重量百分比均匀混合后，涂布在玻璃、PET、PVC、PP等基材上，经加热烘干制得防蓝光涂层。
如上所述的胶水为丙烯酸胶、有机硅胶、PU胶等。
如上所述的紫外线吸收剂为UV-326、UV-531、UV-328中的一种或多种。
如上所述的所述的自由基捕捉剂为受阻胺类自由基捕捉剂如HS-944、LS-622、ZX-70或Cyasorb 3346的一种或多种。
如上所述的抗氧剂为受阻酚类抗氧剂或亚磷酸酯类抗氧剂中的一种或两种，所述的受阻酚类为抗氧剂1010、所述的亚磷酸酯类抗氧剂包括亚磷酸三苯酯、季戊四醇二亚磷酸双十八酯、Antioxidant 24等。
如上所述的所述的偶氮染料为可吸收400nm-425nm蓝光的偶氮类颜料及其金属衍生物，具体如颜料黄3(C.I.Pigment Yellow 3)、颜料黄182(C.I.Pigment Yellow 182)、颜料黄155(C.I.Pigment Yellow 155)或分散黄83、分散黄134中的一种或多种。
如上所述的溶剂为甲苯、乙酸乙酯、甲基异丁基酮、二甲苯、100号溶剂油或120号溶剂油。
与现有技术相比，本发明的有益之处在于：
①相比于传统防蓝光组合物，本发明防蓝光胶水组合物有效吸收对人眼有害的蓝光波段380-425nm的高能波长，对无害的其它波长的光线具有高透过率，以减少产品色调变化，保持显示器的高亮度；
②相比市售防蓝光吸收剂，偶氮类颜料可承受280-290℃不分解，不会对机械设备产生腐蚀，与材料相容性好，价格便宜，能有效降低成本；
③制备工艺简单，无需复杂的阶梯控温步骤，制备所得的防蓝光制品，具有强度高，透光率高，无毒无害，不会向环境释放有毒有害气体，适用范围广。
