带有蛾眼结构的反光膜及其制备工艺
摘要：
本发明提供了一种带有蛾眼结构的反光膜及其制备工艺。反光膜包括PET层、反光结构层、蛾眼减反结构层。反光结构层借助几何光学原理，采用三面互相垂直的金字塔结构作为反光结构。蛾眼减反结构层借助仿生学原理，采用类蛾眼微纳结构作为减反层。与传统的反光膜相比，本发明的反光膜反光效果更好。本发明的制备工艺采用卷对卷的UV双面辊压工艺(R2R UV‑NIL)，包括滴胶、填充、UV光照和脱模。能够在PET层两侧表面压印出不同结构层，制作工艺简单，可以满足快速、大面积、高分辨率、高通量的商业化需求。
摘要（英）：

The present invention provides a reflective film with a moth eye structure and a preparation technology thereof. The reflective film provided by the invention comprises a PET layer, a reflective structure layer and a moth eye anti-reflection structure layer. Through the geometric optics principle, the reflective structure layer is configured to take a pyramid structure with three vertical surfaces as a reflective structure. Through the bionics principle, the moth eye anti-reflection structure layer is configured to take a moth eye micro-nano structure as an anti-reflection layer. Compared with the traditional reflective film, the reflective film provided by the invention has a better reflective effect. Through adoption of reel-to-reel UV two-sided rolling technology (R2R UV-NIL), the preparation technology provided by the invention comprises adhesive dripping, filling, UV illumination and demolding. According to the invention, different structure layers may be printed on the surfaces at two sides of the PET layer; and moreover, the preparation technology is simple, and the fast and large-area commercialization requirement with high resolution and high throughput may be satisfied.
