Problems solved by technology

Because the luminous ink coating formula is not very environmentally friendly, the finished product has a strong smell
In addition, after the ink is printed on ordinary plastic products, the plastic will absorb a certain amount of light, resulting in low luminous efficiency of the product

Abstract

The invention discloses a noctilucent identification tape and a preparation method thereof, and printed patterns give out light itself. The noctilucent identification tape and the preparation method are good in lighting effect, safe and environment-friendly in products and convenient to use. The noctilucent identification tape is divided into seven layers from the front face to the back face, namely a first transparent polyester film layer, a first ethylene (EVA) hot melting glue layer, printing paper, a second EVA hot melting glue layer, a second transparent polyester film layer, a tackiness agent layer and silicon coating protective paper which are sequentially arranged. The preparation method of the noctilucent identification tape comprises the following steps of coating EVA hot melting glue on the surface of a transparent polyester film to form a pre-coating film through an extrusion curtain coating process; coating the tackiness agent on a polyester face of the pre-coating film through a dry-type composite process, forming a back-glue pre-coating film with the silicon coating protective paper after drying; and vertically folding and winding EVA hot melting glue faces of the pre-coating film and the back-glue pre-coating film, and forming a back-glue film through cutting, burnishing and chamfering.

Description

[0001] technical field [0002] The invention relates to a sign sticker, in particular to a luminous sign sticker and a preparation method thereof. The luminous sign sticker relates to polymer chemistry and polymer composite materials. Background technique [0003] Luminous signage is a visible marker at night. Existing luminous signage products mainly include luminous plastic prints and luminous ink prints. [0004] Among them, luminous plastic is produced by blending luminous powder and resin in a certain proportion through extrusion molding, injection molding and other processes. The product can be printed, and it should be stored under the light source before use, so that it can continue to glow at night or in a dark space. Since the material itself emits light, the brightness of the printed pattern is not obvious. Moreover, the production cost of luminous plastic is high, and the market is difficult to engage. [0005] Luminous ink prints are usually printed on plast...
