High-brightness breathable reflective film and preparation method thereof

Abstract

The invention relates to the technical field of reflective films, in particular to a high-brightness breathable reflective film and a preparation method thereof. The high-brightness breathable reflective film comprises a release paper, wherein the lower surface of the release paper is integrally formed with uniformly distributed rack portions, an adhesive layer is provided on the upper surface ofthe release paper, a reflective layer is adhered to the upper surface of the adhesive layer, concave portions are evenly distributed on the upper surface of the reflective layer, transparent waterproof and breathable film is arranged on the upper surface of the reflective layer, and the combination of the reflective layer and glass microbeads can have a reflective effect; the transparent waterproof and breathable film layer can increase the waterproof and breathable effect of the entire reflective film; the intermeshing serrated part I and serrated part II can increase the bonding area of thereflective layer, the waterproof and breathable film layer and the edging layer, thereby increasing the bonding area among the three, so that the edging layer can be used to reduce the phenomenon of curling or warping of the entire composite reflective film.

Description

technical field [0001] The invention relates to the technical field of reflective film, in particular to a high-brightness air-permeable reflective film and a preparation method thereof. Background technique [0002] The reflective film plays an obvious warning role with its bright colors during the day, and its bright reflective effect can effectively enhance people's recognition ability, see the target clearly and arouse vigilance at night or in the case of insufficient light, so as to avoid accidents. Becoming an indispensable safety guard for road traffic has obvious social benefits. At present, the reflective film on the market lacks an edge protection structure, which causes warping and curling of the reflective film during use, thereby affecting the service life of the reflective film; at the same time, the existing reflective film has poor waterproof and breathable performance, which makes the reflective film It is very easy to enter water or cannot dissipate heat, ...

AI Technical Summary

Problems solved by technology

At present, the reflective film on the market lacks an edge protection structure, which causes warping and curling of the reflective film during use, thereby affecting the service life of the reflective film; at the same time, the existing reflective film has poor waterproof and breathable performance, which makes the reflective film It is very easy to enter water or cannot dissipate heat, which is not conducive to the long-term use of the reflective film, so it needs to be improved
