Abstract

The invention relates to a reflective sticker for a backboard module, and especially relates to a reflective sticker, adaptable to different sunlight angles, of dual-hot melt adhesive, and a preparation method of the reflective sticker. For solving the problem that the existing reflective sticker cannot change the parallel reflecting light path and is inadaptable to the different sunlight angles,the invention provides a reflective sticker, capable of changing the parallel reflecting light path, of the dual-hot melt adhesive, and the preparation method of the reflective sticker. The reflectivesticker of the dual-hot melt adhesive comprises a triple prism array; the triple prism array comprises a structure layer and a substrate layer, the structure layer is arranged on the substrate layer,and the structure layer comprises a plurality of triple prism structures; a cross section of each triple prism structure is a triangle, at least one side of the triangle is an arc concave to the triangle, at least one side surface of the triple prism is a concave arc surface, and the concave arc surface is a reflecting plane. The reflective sticker of the dual-hot melt adhesive can enable the reflecting light path to produce a deflection angle, and the linear light source can be modified as non-parallel light path so as to be adapted to different sunlight angles.

Description

technical field [0001] The invention relates to a reflective sticker for a back panel assembly, in particular to a reflective sticker with a concave arc surface triangular prism array microstructure, which can adapt to different sunlight angles and a double hot-melt adhesive layer and a preparation method thereof. Background technique [0002] The cross-section of traditional triangular prisms is generally a standard triangular structure, or even a special equilateral triangle or isosceles triangle. Triangular prisms generally have the following two uses as optical structures: [0003] (1) The three sides corresponding to the three sides are all light-transmitting surfaces, which serve as an optical transmission structure. Usually, the refraction light path on two sides is used as a beam splitter, or the light path of reflection, total reflection, and refraction is used as a mirror, or the light path refracted upward on two sides is used as a condenser, or even a combinatio...
