Abstract
本发明涉及粘合材料技术领域，且公开了一种柔性OLED支撑用保护膜胶带，从上到下依次为第一层基材抗静电丙烯酸压敏保护膜层和PET光学层、丙烯酸胶层和第二层基材PET离型膜层，该胶带产品贴合性能稳定，弯折过程中不脱落采用耐弯折丙烯酸胶黏剂，适用于OLED不同角度弯折提升了器件整体的挺度，防止器件的损伤和有效防止OLED器件在高温情况下因胶带粘性不足而导致器件损坏的风险，也适用于OLED支撑应用、曲面产品应用运输和储存运输及保存温度10‑30℃，相对湿度30％‑70％的情况下，产品最佳使用时间可达6个月，通过丙烯酸压敏保护膜、PET光学层处理以及丙烯酸胶层和PET离型膜处理，使胶带使用时有较好的抗静电性能。
Description
技术领域
本发明涉及粘合材料技术领域，具体为一种柔性OLED支撑用保护膜胶带。
背景技术
OLED生产过程中所需的基板支撑膜，其是一种粘合薄膜，这种支撑膜核心在于易贴、易撕，然而柔性OLED的基板是聚酰亚胺，因此该基板支撑膜是防止其干燥的增强膜，在柔性OLED生产线中，聚酰亚胺基板形成在载体玻璃上，OLED面板通过激光剥离工艺处理，已经通过激光剥离从载体玻璃中取出的PI基底很薄，因此如果不进行处理，很容易发生卷曲，所以一般会贴合防卷曲的支撑膜后进行触摸感应和偏光片贴合等作业，据了解，在传统的OLED封装中，一般采用玻璃基板和玻璃盖板，由于玻璃难以弯曲，传统OLED显示屏无法实现折叠和可卷曲的功能。如果要实现柔性的OLED显示，基板和盖板均需要更换为柔性材料。如论文《一种生物无机材料石质古迹上天然草酸钙保护膜的研究》中报道了一种以草酸钙为主要成分的致密的生物无机膜，其结晶颗粒细密，与基层岩石结合紧密，耐酸性和耐侯好，具有保护岩石表面细微结构的作用，但是其粘性较差，透光率较差。
发明内容
(一)解决的技术问题
针对现有技术的不足，本发明提供了一种柔性OLED支撑用保护膜胶带，提高了胶带的粘性，抗静电，透明度。
