Embodiment Construction
[0042] In order to better understand the above technical solution, the above technical scheme will be described in detail below in conjunction with the specification and specific embodiments.
[0043] A method of preparing a flat-top positive angle microprism reflective material mold including the following steps:
[0044] Step (1): Calculate the planing distance, first design the flat-top microfiroscope unit, and then calculate the data of the unit flat microprism based on the steeled microfiber unit.
[0045] Please refer to figure 1 The angle of the positive angle pyramid bottom is 60 °, that is, ∠A = ∠B = ∠C = 60 °, the triangle of the positive angle pyramid bottom is the equilateral triangle, and its side length is L, high is D; The triangle of the side of the corner prism side is the equal waist lineage triangle, which is long as L · SIN45 °; the height of the pointed positive angle pyramid is h. The sidelines of the top triangle of the top of the pan l The height of the fla...

Abstract
The invention discloses a reflective material mold with a flat-top microprism array and a preparation method thereof. The reflective material mold is formed by a unit flat-top microprism array, and the side surfaces of the unit flat-top microprisms are quadrangular. The present invention uses a V-shaped knife to plan a fine V-shaped groove in the first direction, and then enters the next planing direction to plan a fine V-shaped groove after the first direction is completely planed. The structure has the same unit planar The reflective material mold of the top microprism array; this preparation method not only reduces the number of planing times, improves the mold production efficiency, and reduces the difficulty of planing, but also produces a flat top microprism array reflective material that meets the large-angle incidence and observation conditions. Maintaining the superior characteristics of high retroreflection coefficient helps to improve the visibility of reflective signage in large viewing angle range, especially on high-speed entrance and exit ramps, interchange curve guide roads and other road sections with large visual blind spots, and improves the safe driving factor .
Description
Technical field [0001] The present invention relates to the field of reflective materials, and more particularly to a reflective material mold having a flat-top microprism array and a preparation method thereof. Background technique [0002] The prism technology in the reflective material industry includes a full prism and a large angular microprism reflective film. Among them, the full prism is a modification of the three-priced tapered angle by removing the non-reflective portion of the three corners of the tri-printed cone or the full prism leader structure. Pyramid; existing methods for preparing a full prism, is to complete the full prism unit hindle assembly or structure, from retaining the tap integrity and the consistency, and the preparation is extremely difficult to prepare the toroidal integrity and consistency. [0003] The existing cubic tape is to form a pyramid having three four-side side surfaces by constructing a mold injection molded or assembled microcrystallin...
