Description

应用于折叠手机的OCA胶带
技术领域
本发明是关于柔性材料技术，特别是关于一种应用于折叠手机的OCA胶带。
背景技术
随着科学技术发展及市场新需求，柔性可折叠智能手机于2019年世界移动通信大会面世，为了迎合当下消费者追求便携和功能多样统一的需求，各大手机厂商致力于研究可折叠智能手机。为满足折叠需求，手机内部零件链接胶带需匹配柔性可重复折叠，现有的OCA胶模量相对较大，折弯处应力集中区域易出现断裂或分层。
公开于该背景技术部分的信息仅仅旨在增加对本发明的总体背景的理解，而不应当被视为承认或以任何形式暗示该信息构成已为本领域一般技术人员所公知的现有技术。
发明内容
本发明的目的在于提供一种应用于折叠手机的OCA胶带，通过对OCA胶带的组成和结构进行优化设计，有效地改善了产品的柔性和贴合性能，使其充分满足折叠屏长期使用的要求。
为实现上述目的，本发明的实施例提供了应用于折叠手机的OCA胶带，包括顺次设置的离型层、OCA胶层以及平面离型膜，OCA胶层的原料包括，以重量百分数计：25％～50％丙烯酸酯系共聚物、30％～55％乙酸乙酯、余量为甲苯。
在本发明的一个或多个实施方式中，丙烯酸酯系共聚物的原料包括，以重量百分数计：20％～65％单体、0.1％～4％引发剂、余量为甲苯。优选的，引发剂选自过氧化苯甲酰、过氧化月桂酰、过氧化二异丙苯、过氧化甲乙酮、过氧化环己酮。
在本发明的一个或多个实施方式中，单体为丙烯酸丁酯、丙烯酸乙酯、甲基丙烯酸-2-乙基己酯，丙烯酸月桂酯，甲基丙烯酸一种或多种。
在本发明的一个或多个实施方式中，离型层为PET材质非离型面抗静电，阻抗为106～109Ω。
在本发明的一个或多个实施方式中，离型层满足：厚度75～100μm。
在本发明的一个或多个实施方式中，OCA胶层满足：厚度为25～75μm。
在本发明的一个或多个实施方式中，平面离型层为PET离型面抗静电，阻抗为106～109Ω。
在本发明的一个或多个实施方式中，平面离型层满足：厚度50～75μm。
与现有技术相比，根据本发明实施方式的应用于折叠手机的OCA胶带，通过采用特定的OCA胶层原料设计，采用特别组成的丙烯酸酯系共聚物为依托，改善树脂胶粘结构的结晶性，从而提升产品的柔性粘接性，从而极大地改善了产品的性能。优化后的OCA胶层具有低模量、低TG、蠕变恢复高等特性，满足常温/高温高湿/低温环境下折叠需求，从而降低折弯处普通OCA断裂或分层的风险。
