Description

紫外光固化胶黏剂原胶、紫外光固化胶黏剂 技术领域
本发明涉及胶黏剂领域，尤其涉及一种紫外光固化胶黏剂原胶、紫外光固化胶黏剂。
背景技术
高分子胶粘剂被广泛地用于粘结物质，随着科技的进步，胶黏剂已发展成为生活用品、电子产品等不可或缺的产品。紫外光固化胶粘剂因其不需要加热高温固化，能够在常温下通过紫外线固化，而被广泛应用于各个行业中。然而，目前在户外使用的紫外固化胶黏剂大多不具备紫外屏蔽功能，在阳光下，受胶粘剂粘接的物质易受紫外线影响而受损伤。
如此需要现有的胶黏剂的成分进行改进，设计出一种有着高强度的粘接能力、紫外屏蔽能力、抗形变能力的新型的紫外光固化胶黏剂。
发明内容
为了克服现有技术的不足，本发明的第一个目的是提供一种紫外光固化胶黏剂原胶，所述原胶包括以下重量份的原料：

剩余重量为液相聚合反应中添加的溶剂。

相比现有技术，本发明的有益效果在于：本发明提供一种紫外光固化胶黏剂原胶，所述胶黏剂包括以下重量份的原料：丙烯酸类单体40-60份；引发剂0.1-1份；催化剂0.1-1份；紫外改性剂0.1-1份；阻聚剂0.1-1份；剩余重量为液相聚合反应中添加的溶剂。本发明还提供了一种紫外光固化胶黏剂。通过本发明的原胶形成的胶黏剂可以在保持高可见光透过率的同时，大幅阻隔400nm波段以下的紫外光。
本上述说明仅是本发明技术方案的概述，为了能够更清楚了解本发明的技术手段，并可依照说明书的内容予以实施，以下以本发明的较佳实施例详 细说明如后。本发明的具体实施方式由以下实施例详细给出。
具体实施方式
下面，结合具体实施方式，对本发明做进一步描述，需要说明的是，在不相冲突的前提下，以下描述的各实施例之间或各技术特征之间可以任意组合形成新的实施例。
现有的在户外使用的紫外固化胶黏剂大多不具备紫外屏蔽功能，在阳光下，受胶粘剂粘接的物质易受紫外线影响而受损伤；另外，现有的紫外固化后胶粘剂在户外长期使用中会面临滑移甚至脱落的问题。本发明涉及一种紫外光固化胶黏剂原胶，该原胶包括以下重量份的原料：
Figure PCTCN2022134941-appb-000002
剩余重量为液相聚合反应中添加的溶剂。本发明的原胶具备紫外屏蔽功能，可避免户外长期使用面临滑移甚至脱落的问题。
为了提升最终原胶的综合性能，在一些实施例中，丙烯酸类单体为软单体、硬单体和功能单体的混合物。
为了获取更好的综合性能，在一些实施例中，软单体、硬单体与功能单体之间的质量比在(5-10)：(2-4)：(1-3)。
应当理解，紫外改性剂可为现有技术中任意常见的紫外改性剂。
在一些实施例中，软单体为丙烯酸正辛酯、丙烯酸丁酯、丙烯酸乙酯、丙烯酸异辛酯和甲基丙烯酸酯长链单体中的至少一种；其中，甲基丙烯酸酯长链单体中的碳链长度在8个C以上。在一些实施例中，甲基丙烯酸酯长链单体为甲基丙烯酸异辛酯、甲基丙烯酸月桂酯以及甲基丙烯酸十四酯中的至少一种。
为了保证最终原胶的强度、硬度等性能，在一些实施例中，硬单体为丙烯酸、丙烯酸甲酯、甲基丙烯酸、甲基丙烯酸甲酯、甲基丙烯酸正丁酯和甲基丙烯酸乙酯中的至少一种。
为了贴合最终原胶的功能性，在一些实施例中，功能单体为丙烯酰胺、丙烯酸羟乙酯、丙烯酸羟丙酯以及丙烯酸异冰片酯中的至少一种。
引发剂可为现有技术中的任意引发剂。在一些实施例中，为了保证胶黏剂的性能，引发剂为有机过氧化物，其在60-80℃时的反应活性不宜过高。
本发明中紫外光固化胶黏剂原胶的制备方法，具体包括以下步骤：
步骤一：将软单体、功能单体以及硬单体加入反应容器中，并在>60℃,120r/min的条件下进行搅拌20min以上，得到混合物A；
在一些实施例中，软单体为丙烯酸异辛酯，功能单体为丙烯酸羟乙酯、丙烯酸异冰片酯、丙烯酰胺，硬单体为丙烯酸甲酯。
应当理解，软单体、硬单体、功能单体可为一种相应单体或多种相应单体的混合。
步骤二：在混合物A中加入引发剂过氧化二苯甲酰，在沸腾温度回流反应1h，得到混合物B；
步骤三：在混合物B中加入引发剂过氧化二苯甲酰，继续反应1.5h，得到混合物C；
步骤四：在混合物C中加入引发剂过氧化二苯甲酰，继续反应2.5h，得到混合物D；
步骤五：在混合物D中加入阻聚剂，隔绝空气，在密闭体系中搅拌十分钟，而后依次加入紫外改性剂与催化剂，在50℃下低温接枝8h，得到紫外光固化胶粘剂原胶。
本发明还涉及一种紫外光固化胶黏剂，包括以下重量份的原料：
如上的紫外光固化胶黏剂原胶100份，热固化剂0.05-0.1份，紫外屏蔽剂0.5-3份，光固化单体1-4份，光引发剂0.1-2份，光稳定剂0.1-2份， 硅烷偶联剂0.01-0.1份；由此制备的紫外光固化胶黏剂可在保持高可见光透过率的同时，大幅阻隔400nm波段以下的紫外光；并且此胶粘剂在紫外固化前模量较低，初黏较高，故可在紫外固化前较为牢固地粘接物质；而在紫外固化后模量有较大的提升，从而减少受粘结的部件在室外长期使用时可能会产生的相对滑移甚至脱落，同时也能减少部件与胶面可能产生的回弹起泡现象。
在一些实施例中，为了平衡胶黏剂的耐紫外性能和紫外固化反应这一对矛盾点，光引发剂与光稳定剂质量比为1：(0.2-5)。研究发现，当光引发剂和光稳定剂质量比小于1：0.2时，产品会明显发黄(b值>1)；当光引发剂和光稳定剂质量比大于1：5时，会对紫外固化产生影响，从而造成UV后模量无法提升，抗形变能力下降。
应当理解，所谓以下重量份的原料具体以去除溶剂后的干胶比计算。
应当理解，热固化剂可为任意现有技术中的热固化剂。在一些实施例中，为了保证固化效果，热固化剂为异氰酸酯类固化剂，包括六亚甲基二异氰酸酯、缩二脲多异氰酸酯、(氢化)苯二甲基二异氰酸酯的脂肪族聚异氰酸酯加成物、甲苯二异氰酸酯、间苯二甲基异氰酸酯、二苯基甲烷二异氰酸酯等中的至少一种。
为了保证最终胶黏剂的紫外屏蔽效果，在一些实施例中，紫外屏蔽剂为二苯甲酮类紫外线吸收剂或苯并三唑类紫外线吸收剂。具体地，紫外屏蔽剂为二苯甲酮类紫外线吸收剂时，具体可为2,4-二羟基二苯甲酮/2,4-二羟基苯甲酮(UV-0/BP-1)，2,2'-羟基-4-甲氧基二苯甲酮/2,2-二羟基-4-甲氧基苯甲酮(UV-24/BP-8)等，紫外屏蔽剂为苯并三唑类紫外线吸收剂时，具体可为2-(2'-羟基-5'-甲基苯基)苯并三氮唑(UV-P)等。
应当理解，部分紫外屏蔽剂会影响可见波段光的透过率，并使胶黏剂显现一定程度的黄色；紫外屏蔽剂的选择需要根据实际需求调整。
在一些实施例中，为了保证固化效果，光固化单体可选用双官能团以上 的丙烯酸酯类活性稀释剂，即交联单体；典型的双官能团类稀释剂有二乙二醇二丙烯酸酯(DEGDA)，三乙二醇二丙烯酸酯(TEGDA)等，典型的三官能团类稀释剂有三羟甲基丙烷三丙烯酸酯(TMPTA)，季戊四醇三丙烯酸酯(PETA)等。通过添加一定量的光固化单体如交联单体，以使紫外固化后的胶黏剂实现较高的模量抬升，从而减少受粘结的部件在室外长期使用时可能会产生的相对滑移甚至脱落，同时也能减少部件与胶面可能产生的回弹起泡现象。使用不同种类的光固化单体会使模量的变化有显著差异。
在一些实施例中，为了保证引发效率，光引发剂为自由基裂解型光引发剂，如可选用2,4,6-三甲基苯甲酰基(TPO)，1-羟基环已基苯基甲酮(光引发剂184)，二苯甲酮(BP)，2-羟基-2甲基-苯基丙酮-1(1173)等有一定吸收能力的高效光引发剂。
应当理解，部分光引发剂会使胶粘剂显现一定程度的黄色，光引发剂的选择需要根据实际需求调整。
在一些实施例中，为了保证胶黏剂的耐紫外性，光稳定剂为普通市售产品，如可选用光稳定剂2020，光稳定剂1130，光稳定剂119等。
在一些实施例中，为了保证胶黏剂的粘结效果，硅烷偶联剂可以选用硅烷偶联剂有乙烯基三乙氧基硅烷、乙烯基三甲氧基硅烷、乙烯基三(β-甲氧乙氧基)硅烷等。
