一种高耐侯性光学胶薄膜胶片及其制作工艺
摘要：
本发明涉及液晶显示屏技术领域，具体涉及一种高耐侯性光学胶薄膜胶片及其制作工艺，包括从下往上依次贴合的轻离型膜、光学胶层和重离型膜，所述光学胶层包括以下重量份的原料：丙烯酸酯单体80‑120份、增稠剂4‑8份、固化剂2‑6份、引发剂1‑5份、偶联剂1‑3份、消泡剂1‑2份、抗紫外线剂0.5‑1.5份、抗氧化剂0.8‑1.2份。本发明的高耐侯性光学胶薄膜胶片通过在光学胶中加入UV固化剂，经过高温消泡、UV固化制程，可以很好的压制气泡反弹，且模切良率可以达到94%以上。
摘要（英）：

The invention relates to the technical field of liquid crystal displays, in particular to a high weatherability optical adhesive film and a making process thereof. The high weatherability optical adhesive film comprises a light release film, an optical glue layer and a heavy release film that are glued from the bottom up in order. The optical glue layer comprises the following raw materials by weight: 80-120 parts of an acrylate monomer, 4-8 parts of a thickener, 2-6 parts of a curing agent, 1-5 parts of an initiator, 1-3 parts of a coupling agent, 1-2 parts of a defoaming agent, 0.5-1.5 parts of an anti-ultraviolet agent, and 0.8-1.2 parts of an antioxidant. According to the high weatherability optical adhesive film provided by the invention, the UV curing agent is added into the optical glue, high temperature defoaming and UV curing processes are carried out, bubble rebound can be well suppressed, and the die cut yield can reach 94% or more.
