Abstract

The invention discloses a light storage film and belongs to the technical field of light storage films. The light storage film comprises a surface layer, a light storage layer, a light shading layer,a backing adhesive layer and release paper, the light shading layer is a lightproof white PET or BOPP film, a wave point groove for focusing light penetrating the light storage layer is arranged on one side, close to the light storage layer, of the light shading layer, and a reflection layer coats the surface of the wave point groove. Under the circumstance that patterns at each position are displayed clearly, a position corresponding to the wave point groove can focus the light penetrating the light storage layer, and the center of the wave point groove absorbs more light energy, so that thelight storage film is longer in luminous time and can be widely applied in the field of outdoor advertisement and road traffic.

Description

technical field [0001] The invention discloses a light storage film and a preparation method thereof, belonging to the technical field of light storage films. Background technique [0002] Light storage film is a combination of polymer material and light storage powder, which is formed into a film with a certain thickness by extrusion or coating process. Widely used in subways, shopping malls, safe passages of high-rise buildings, house numbers and other fields, it plays a clear and guiding role in the dark. The main structure of the currently popular light storage film is: surface layer, light storage layer, reflective layer, adhesive layer and backing paper. According to different usage occasions, some have no surface layer, and some adhesive layers are in front of the light storage layer to form a reverse light storage film. However, the existing light storage film has low luminous brightness, short time and short service life, so it needs to improve. Contents of the ...
