Colorful high-brightness hot-sticking reflective cloth and manufacturing process

Abstract

The invention discloses a colorful high-brightness hot-sticking reflective cloth. The colorful high-brightness hot-sticking reflective cloth comprises a base material (1), a bead planting layer (2), glass microbeads (3), a zinc sulfide layer (4), an aluminum layer (5) and a hot melt adhesive layer (6), wherein the thickness of the base material (1) is 10-125 microns; the bead planting layer (2) is arranged at the lower surface of the base material (1); a plurality of glass microbeads (3) with different particle diameters are arranged between the zinc sulfide layer (4) and the bead planting layer (2); the lower half part of each microbead is embedded into the zinc sulfide layer (4); the particle-diameter size of each glass microbead (3) is 5-120 microns; the refractive index of the glass microbeads is 1.90-1.93; and the thickness range of the bead planting layer (2) is more than 0.1 micron and is less than one third of the average particle diameter of the glass microbeads (3). The colorful high-brightness hot-sticking reflective cloth disclosed by the invention has the beneficial effects that the manufacturing process is simple, the colorful effect is good, the retro-reflecting coefficient is high, the increasingly individualized and fashionable market demand for customers can be met, and the product can be used for character engraving and hot sticking.

Description

technical field [0001] The invention relates to the technical field of production of reflective materials, in particular to a colorful and high-brightness hot-post reflective cloth and a manufacturing process thereof. Background technique [0002] The current high-brightness hot-post reflective cloth is made of glass beads with a refractive index of 1.90~1.93. The manufacturing process of this colorful high-brightness hot-post reflective cloth is: first on the glued PET or on the PE composite film, Adhere glass microspheres of different particle sizes on it, and then vapor-deposit in a vacuum coating machine, then apply compound glue on the release PET, compound with the aluminum-coated bead-planting film, peel off the release PET, and hot melt adhesive Film composite, thus realizing the manufacture of colorful high-brightness hot-post reflective cloth. This kind of reflective cloth can not only be hot-posted, but also has a high retroreflection coefficient, but it is a sin...

AI Technical Summary

Problems solved by technology

This kind of reflective cloth can not only be hot-posted, but also has a high retroreflection coefficient, but it is a single gray color, which cannot meet the increasingly personalized and fashionable market needs of customers; It has obvious dazzling colors and is welcomed by customers, but the retroreflection coefficient is low, which is only equivalent to about one-twentieth to one-fourth of the retroreflection coefficient of aluminized reflective cloth, which cannot meet some high requirements for retroreflection coefficient. Therefore, although the hot-post reflective cloth coated with galvanized sulfide meets some individual requirements, it is not as good as the aluminum-plated hot-post reflective cloth in terms of safety performance as a warning.
