Description
技术领域
本发明涉及LED封装胶及其制作方法技术领域，尤其涉及一种防炫光LED封装胶水配方及其制作方法。
背景技术
LED光源寿命长、光效高、无辐射与低功耗，被广泛应用于各种显示屏、汽车灯以及各种电子产品的背光源以及照明用等，其封装材料的选择对LED的性能影响至关重要；目前所用封装材料有聚甲基丙烯酸甲酯、玻璃、有机硅等高透明材料，有机硅材料，内应力小，耐高低温性能好，不黄变，但是存在与基材粘接性差，导致封装失败，或者耐老化性能性能下降，而且由于生产工艺落后，封装后的LED密封性能等不太稳定，造成LED使用寿命短。
发明内容
针对上述技术中存在的不足之处，本发明提供一种防炫光LED封装胶水配方及其制作方法。
为了达到上述目的，本发明一种防炫光LED封装胶水配方，包括A组分和B组分；
所述A组分重量份数比包括脂环族环氧树脂100份、抗氧剂0.01-5份、促进剂A0.01-5份、哑光粉1-200份和消泡剂0.01-5份；
所述B组分重量份数比包括酸酐60-150份、抗氧剂0.01-5份、促进剂B0.01-5份和消泡剂0.01-5份；
A组分中环氧基与B组分中酸酐的摩尔比为100:40-100:160。
其中，所述脂环族环氧树脂是3，4-环氧环己基甲基3，4-环氧环己基甲酸酯、3,4-环氧环己烷羧酸甲酯、双(2,3-环氧基环戊基)醚、2，3-环氧基环戊基环戊基醚和二环戊二烯二环氧化物中的一种或者其中多种的组合。
其中，所述抗氧剂是3-(3，4-二叔丁基-4-轻基苯基)丙酸正十八烷醇酯、2，3-三级丁基-4-甲基苯酚、双(3，5-三级丁基-4-羟基苯基)硫醚和四〔β-(3，5-三级丁基-4-羟基苯基)丙酸〕季戊四醇酯中的一种或者多种的组合。
其中，所述促进剂A为N-(2-氰基乙基)己内酰胺或β二酮金属络合物；所述促进剂B为乙基三苯基碘化磷、三苯基磷、四甲基溴化铵、四乙基溴化铵或四丁基溴化铵中的一种。
其中，所述β二酮金属络合物是结构为X-CO-CH2-CO-Y的β二酮与铜、钴、锌、锆、铝、锰、铬或镍形成的络合物。
其中，所述哑光粉为二氧化硅，二氧化硅粉末的平均粒径为1nm-100μm；所述酸酐是甲基六氢苯酐和六氢邻苯二甲酸酐的其中一种或者两种的组合物。
本发明还公开了一种防炫光LED封装胶水配方的制作方法，包括以下步骤：
S1、制备A组分：按重量计，将100份脂环族环氧树脂、0.01-5份抗氧剂、0.01-5份促进剂、1-200份哑光粉和0.01-5份消泡剂混合，并搅拌至混合均匀，得到A组分。
S2、制备B组分：按重量计，将60-150份酸酐、0.01-5份抗氧剂、0.01-5份促进剂和0.01-5份消泡剂混合，并搅拌至混合均匀，得到B组分。
S3、A组分与B组分混合：按照组分中环氧基与组分中酸酐的摩尔比为100：40-100:160的比例，将A组分和B组分混合，并搅拌至混合均匀，得到所需的环氧树脂封装胶。
与现有技术相比，本发明的防炫光LED封装胶水配方及其制作方法的有益效果：
1、具有电气绝缘性能和耐高低温性能；
2、使得LED的出光面为亚光表面，不反光或微弱反光；
3、将传统的点光源的点出光转化成面出光，出光一致性好，光线柔和，能解决LED出光为眩光的问题。

A组分中环氧基与B组分中酸酐的摩尔比为100:40-100:160。
与现有技术相比，本发明的防炫光LED封装胶水配方及其制作方法的有益效果：
1、具有电气绝缘性能和耐高低温性能；
2、使得LED的出光面为亚光表面，不反光或微弱反光；
3、将传统的点光源的点出光转化成面出光，出光一致性好，光线柔和，能解决LED出光为眩光的问题。
在本发明中，所述脂环族环氧树脂是3，4-环氧环己基甲基3，4-环氧环己基甲酸酯、3,4-环氧环己烷羧酸甲酯、双(2,3-环氧基环戊基)醚、2，3-环氧基环戊基环戊基醚和二环戊二烯二环氧化物中的一种或者其中多种的组合。
在本发明中，所述抗氧剂是3-(3，4-二叔丁基-4-轻基苯基)丙酸正十八烷醇酯、2，3-三级丁基-4-甲基苯酚、双(3，5-三级丁基-4-羟基苯基)硫醚和四〔β-(3，5-三级丁基-4-羟基苯基)丙酸〕季戊四醇酯中的一种或者多种的组合。
在本发明中，所述促进剂A为N-(2-氰基乙基)己内酰胺或β二酮金属络合物；所述促进剂B为乙基三苯基碘化磷、三苯基磷、四甲基溴化铵、四乙基溴化铵或四丁基溴化铵中的一种。
在本发明中，所述β二酮金属络合物是结构为X-CO-CH2-CO-Y的β二酮与铜、钴、锌、锆、铝、锰、铬或镍形成的络合物。
在本发明中，所述哑光粉为二氧化硅，二氧化硅粉末的平均粒径为1nm-100μm；所述酸酐是甲基六氢苯酐和六氢邻苯二甲酸酐的其中一种或者两种的组合物。
本发明还公开了一种防炫光LED封装胶水配方的制作方法，包括以下步骤：
S1、制备A组分：按重量计，将100份脂环族环氧树脂、0.01-5份抗氧剂、0.01-5份促进剂、1-200份哑光粉和0.01-5份消泡剂混合，并搅拌至混合均匀，得到A组分。
S2、制备B组分：按重量计，将60-150份酸酐、0.01-5份抗氧剂、0.01-5份促进剂和0.01-5份消泡剂混合，并搅拌至混合均匀，得到B组分。
S3、A组分与B组分混合：按照组分中环氧基与组分中酸酐的摩尔比为100：40-100:160的比例，将A组分和B组分混合，并搅拌至混合均匀，得到所需的环氧树脂封装胶。
以上公开的仅为本发明的几个具体实施例，但是本发明并非局限于此，任何本领域的技术人员能思之的变化都应落入本发明的保护范围。
