Self-luminous advertising sticker

Abstract

The invention relates to a self-luminous advertising film, which realizes light storage and light emission of the advertising film through special materials of the film. The raw materials are calculated in parts by weight: 20-30 parts of rosin-based hyperbranched polyester acrylate resin, 15-25 parts of alkaline earth metal aluminosilicate powder, 10-25 parts of phthalate, 5-25 parts of polyvinyl chloride 15 parts, 1-5 parts of additives, the advertising effect is good, no light source is needed, it can emit light by itself, the picture is clear and bright, not only saves energy, but also can emit light for more than ten hours after only 20 minutes of light storage.

Description

technical field [0001] The invention relates to a self-luminous advertising film, which realizes light storage and light emission of the advertising film through special materials of the film. Background technique [0002] Traditional luminescent sheets and films use luminescent powder or pigment coating on the surface to achieve self-luminous emergency signs and indication effects. However, there are shortcomings such as too short luminous time, too simple pattern, complicated installation, and narrow application. Moreover, due to the limited thickness of the coating, the surface is easily scratched, damaged or corroded, and the ink absorption performance of the coating is poor, so it is difficult to maintain it for a long time. At present, there are some light-storing and self-luminous luminous films on the market, which are made of polymethyl methacrylate (PMMA resin for short) and rare earth aluminate coating, but polymethyl methacrylate is a thermosetting resin, and th...

Problems solved by technology

However, there are shortcomings such as too short luminescence time, too simple pattern, complicated installation, and narrow application area.

And due to the limited thickness of the coating, the surface is easily scratched, damaged or corroded, and the ink absorption performance of the coating is poor, so it is difficult to maintain for a long time

At present, there are some light-storing and self-luminous luminous films on the market, which are made of polymethyl methacrylate (PMMA resin for short) and rare earth aluminate coating, but polymethyl methacrylate is a thermosetting resin, and there are Many inherent shortcomings, extremely inconvenient to use
