Compared with prior art, the beneficial effects of the present invention are:
1, light shield layer uses lighttight white PET or BOPP film, only needs when producing light storage film by itself and light storage
Compound, the simple production process of layer improves titanium dioxide in traditional window layer and is unevenly distributed that cause light storage film light transmission occur existing
The deficiency of elephant.
2, by increasing the wave point slot of array distribution close to the one side of light storage layer in light shield layer, while the surface of wave point slot is attached
Have reflecting layer, overall structure is identical as concave mirror, and light passes through and is gathered in some point of light storage layer through reflecting after light storage layer
On, and by light-accumulating powder by light energy absorption, compared with traditional light storage film, the light storage film in the present invention can clearly show that each position
In the case where pattern, the light after absorbing reflection is concentrated in the position of corresponding wave point slot, so that the display time of light storage film is longer,
And it also added fire retardant and heat stabilizer in light storage layer, it is ensured that light storage film will not under conditions of strong light and optically focused
There is a phenomenon where spontaneous combustions or dissolution to fall off.
3, the surface layer of the material based on PMMA is increased by the surface in light storage layer, can carry out silk-screen or carving
It carves, it, will not there is a phenomenon where turn yellow to improve the diversity of light storage film surface pattern, while its good weatherability.
