Air brushing light reflection film and preparation technology thereof

Abstract

The invention discloses an air brushing light reflection film, and belongs to the technical field of light reflection films. The air brushing light reflection film comprises a light reflection surfacelayer, a light reflection layer containing glass beads and a resin layer, a reflection layer, a back adhesive layer and release paper, wherein the light reflection surface layer, the light reflectionlayer, the reflection layer, the back adhesive layer and the release paper are arranged in sequence from top to bottom. The preparation technology for the air brushing light reflection film comprisesthe following steps that: (1) implanting glass beads; (2) coating a splicing layer; (3) carrying out embossing; (4) coating the back adhesive layer, and pasting the release paper; (5) coating an airbrushing layer; and (6) coating an acid and alkali resistant protection layer. Compared with a traditional light reflection film, the air brushing light reflection film can carry out pattern air brushing on the surface and improve the warning effect of the light reflection film, in addition, the acid and alkali resistant protection layer attached to the surface of the air brushing layer to greatlyenhance the weather resistance of the light reflection film, the phenomenon of ageing, yellowing or falling generated by an external environment can be reduced, and the air brushing light reflectionfilm can be widely applied to fields, including road traffic, buildings and the like.

Description

technical field [0001] The invention discloses an inkjet reflective film and a preparation process thereof, belonging to the technical field of reflective film. Background technique [0002] Common reflective films are mainly used in highway traffic signs, industrial safety signs, license plates and other fields. It is rare for large-scale outdoor advertisements. This is because the production of reflective film for outdoor advertisements is relatively complicated. Generally, silk screen printing or engraving is used, and inkjet printing is rarely used. And at present, even if a few manufacturers make reflective film for inkjet printing, because they are directly spray-painted on the surface of the reflective film, no corresponding protective measures have been taken after printing, and the weather resistance of the ink layer is poor, which makes the service life of the reflective film limited. , This has caused great restrictions on the application of the entire reflective...

Problems solved by technology

It is rare to use large-scale outdoor advertisements. This is because the production of reflective films for outdoor advertisements is relatively complicated. Generally, silk screen printing or engraving is used, and inkjet printing is rarely used.

And at present, even if a few manufacturers make reflective film for inkjet printing, because they are directly spray-painted on the surface of the reflective film, no corresponding protective measures have been taken after printing, and the weather resistance of the ink layer is poor, which makes the service life of the reflective film limited. , which greatly restricts the application of the entire reflective film

In addition, due to the fact that in the prior art, aluminum is directly plated behind the glass bead layer as a reflective layer, and then pressure-sensitive adhesive and release paper are coated on the outside of the reflective layer. It is more susceptible to environmental corrosion, which in turn will affect the service life of the entire reflective film
