Abstract

The utility model provides a dull polish reflective membrane belongs to dull polish reflective membrane technical field. The reflective film solves the technical problems that the existing reflective film can not work normally in rainy days or in the middle of a transparent medium. The frosted reflective film comprises a surface layer, a plant layer, a focusing layer, a back adhesive layer and a back paper layer which are sequentially arranged from top to bottom, wherein the surface layer is a frosted PET (polyethylene terephthalate) layer, glass beads are uniformly distributed between the plant layer and the focusing layer, and a coating layer is arranged on the lower end surface of the focusing layer. The utility model discloses change glossy surface course into the PET layer of surface dull polish, become the diffuse reflection with the original specular reflection of reflective membrane, even the surface attachment of reflective membrane has the drop of water or is separating transparent medium (like glass) also can normal reflection light, makes this reflective membrane can be noticed, has solved the problem that ordinary square light membrane can't normally reflect light when rainy day or separating glass.

Description

Frosted reflective film

Technical Field

The utility model belongs to the technical field of the reflective membrane, refer in particular to a dull polish reflective membrane.

Background

At present, the existing reflective film can have better reflective performance only under the condition of no shielding, when the reflective film is covered with water drops or transparent media (such as glass), the reflective performance of the reflective film can become poor or even basically no longer reflect light, and the situation can bring inconvenience, for example, when the reflective film is applied to an automobile license plate, the automobile license plate is difficult to see at night in rainy weather, or a warning symbol stuck to the glass cannot be seen at night, and the like.

Disclosure of Invention

The utility model aims at providing a wider reflective membrane of adaptability.

The purpose of the utility model is realized like this:

a dull polish reflective membrane which characterized in that: the surface layer is a ground PET layer, glass beads are uniformly distributed between the plant layer and the focusing layer, and a coating layer is arranged on the lower end face of the focusing layer.

In the frosted reflecting film, the thickness of the surface layer is 4-6 threads, the thickness of the plant layer is 2.6-3 threads, the diameter of the glass beads is 7-8 threads, the thickness of the focusing layer is 1.8-2 threads, the thickness of the back glue layer is 4-6 threads, and the thickness of the back paper layer is 7-8 threads. Preferably, the thickness of the surface layer is 5 threads, the thickness of the plant layer is 2.8 threads, the diameter of the glass bead is 7.5 threads, the thickness of the focusing layer is 1.9 threads, the thickness of the back glue layer is 5 threads, and the thickness of the back paper layer is 7.5 threads; with 1 filament being 10 microns.

In the above frosted reflective film, the back adhesive layer is made of white pressure-sensitive adhesive, and the back paper layer is a PET layer.

A preparation method of a frosted reflecting film is characterized by comprising the following steps: the preparation method comprises the following steps:

A. inverting the surface layer to enable the back of the surface layer to face upwards, and then coating a plant layer made of an acrylic resin material on the surface layer, wherein the thickness of the plant layer is 2.8 threads;

B. uniformly distributing glass beads on the plant layer, coating a focusing layer on the glass beads, filling gaps among the glass beads with the focusing layer, completely covering the glass beads, wherein the thickness of the focusing layer is 1.8-2 threads, and arc-shaped bulges matched with the glass beads are formed on the focusing layer;

C. plating aluminum on the focusing layer to form a coating layer;

D. coating white pressure-sensitive adhesive on the coating layer to form a back adhesive layer, wherein the thickness of the back adhesive layer is 5 filaments;

E. and covering the back adhesive layer with PET with the thickness of 7.5 filaments to form a back paper layer.

Compared with the prior art, the utility model outstanding and profitable technological effect is:

the utility model discloses change glossy surface course into the PET layer of surface dull polish, become the diffuse reflection with the original specular reflection of reflective membrane, even the surface attachment of reflective membrane has the drop of water or is separating transparent medium (like glass) also can normal reflection light, makes this reflective membrane can be noticed, has solved the problem that ordinary square light membrane can't normally reflect light when rainy day or separating glass.
