Do you know prismatic reflective film?
Prismatic reflective film:
A reflective material made based on the refraction and total reflection principle of cubic corner pyramids. The surface finish of each cubic corner pyramid exceeds 5nm (nanometers), the angle error is less than 0.01 arc seconds, and there are 10,000 microprisms distributed per square centimeter. It is a reflective product that is completely realized by ultra-precision technical technology and processes.
Compared with glass bead reflective film, it has better reflective effect, longer viewing distance and better recognition effect, and is generally used for road signs on high-grade highways.
Prismatic reflective film product features:
- . Excellent product performance
- High reflectivity
- Highly controllable reflective angle, distance and direction
With the continuous increase in motor vehicle speeds and increasingly complex road conditions, the application market for prismatic reflective film will become increasingly broad. In special climates such as foggy, rainy, snowy days and at night, it can ensure that the signboard is clearly visible.
Technical field:
The utility model relates to a reflective material, in particular to a prismatic reflective film.
Background technology:
Prismatic reflective film has excellent retro-reflective performance and excellent weather resistance and aging resistance, and is widely used in various safety fields.
At present, the micro-prismatic reflective film adopts the manufacturing process of hot pressing. First, the micro-prism and the base material are hot pressed into a reflective film, and then a layer of metal aluminum layer is plated. However, the hot-pressed pyramid is easily damaged and deformed when affected by external factors such as extrusion, weather changes, and water washing, resulting in a significant decrease in the reflective function, and the consistency of the reflective brightness of the material cannot be maintained, which is easy to cause safety hazards. In addition, the metal aluminum layer is easily oxidized, and it is easy to fall off after medium and high temperature water washing, and the metallic luster is lost, which greatly reduces the service life.
Therefore, how to produce a micro-prismatic reflective film that can maintain consistent reflective brightness under external conditions, resist medium and high temperature water washing, and the aluminum layer is not easily oxidized, and the service life is increased is a technical problem to be solved.
In order to overcome the above-mentioned shortcomings in the prior art, the purpose of the utility model is to provide a micro-prismatic reflective film.And qith the purpose of achieving the above-mentioned purpose, the utility model adopts the following specific technical solutions:
A micro-prismatic reflective film comprises a photocurable resin layer and a PVC film layer, wherein the photocurable resin layer and the PVC film layer are pressed into an integrated micro-prismatic structure layer through a micro-prismatic mold, wherein a metal aluminum layer is plated on the PVC film layer, and a resin layer is coated on the metal aluminum layer.
The advantages of the utility model compared with the prior art are:
- The reflective effect of the micro-prismatic structure formed by UV curing of the utility model is more uniform than that of the hot pressing, and the production efficiency is relatively high. It is not easily damaged under various adverse factors in the outside world, and the reflective function will not decrease;
- The resin coated on the aluminum-plated layer can well protect the aluminum layer from oxidation, and is resistant to high-temperature washing, so that the reflective film will not fail to play a role due to the blackening or shedding of the aluminum layer.
