Embodiment Construction

[0029] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.

[0030] The present invention provides a light-emitting reflective film, wherein the light-emitting reflective film is sequentially bonded by a PET film 1, a light-emitting layer 3, and a reflective layer 5, and a first layer of adhesive 2 is coated on the surface of the PET film 1, Attach the light-emitting layer 3 on the first layer of adhesive 2, then coat the second layer of adhesive 4 on the light-emitting layer 3, and attach the reflective layer 5 on the second layer of adhesive 4, so The reflective layer 5 is laminated by resin, glass beads and aluminum foil, a third layer of adhesive is coated on the first layer of resin, and the aluminum foil layer is folded on the third layer of adhesive. Glass beads are embedded in the folds of the aluminum foil layer, a fourth laye...

Abstract

The invention discloses a light-emitting reflection film. The light-emitting reflection film is formed by attaching a PET film (1), a light-emitting layer (3) and a reflection layer (5) sequentially, the surface of the PET film (1) is coated with a first layer of adhesives (2), the light-emitting layer (3) is attached to the first layer of adhesives (2), the light-emitting layer (3) is further coated with a second layer of adhesives (4), the reflection layer (5) is attached to the second layer of adhesives (4), and the reflection layer (5) is formed by pressing resin, glass bead materials and an aluminum foil layer. According to the light-emitting reflection film, the base film is coated with light-emitting materials and reflection materials alternately, the refection materials adopt the light-emitting performance of the light-emitting materials, the capacity of recognizing a signboard is improved for a person in dark, the person can see a target clearly, and safety hidden dangers are reduced. The light-emitting materials adopt the principle of reverse reflection of the reflection materials, so that the reflection intensity of the light-emitting reflection film is improved.

Description

technical field [0001] The invention relates to a thin film material, in particular to a thin film material with dual functions of light emission and light reflection. Background technique [0002] At this stage, there are two types of reflective materials and luminescent materials on the market. Among them, luminescent film is a soft plastic composite film that can store light and emit light; so luminescent film is also called light storage film. The surface of the luminescent film can absorb the energy of the irradiated light, and when the illuminance on the surface is lower than a certain value, it can emit visible light. Luminescent film is an important functional material, which plays a very important role in cathode ray tubes, electroluminescence and field emission display devices. [0003] At present, the luminescent material in the luminescent film is mainly photo-induced energy storage long afterglow luminescent material, which has two main branches, namely zinc su...
