Embodiment 1

[0032] A double-sided adhesive light-shielding adhesive tape, comprising a substrate layer and an adhesive layer arranged on both sides of the substrate layer, and a release layer attached to the adhesive layer, the release layer is a PET release film, The substrate layer includes a black layer and a white layer, and two layers of adhesive layers are respectively arranged on the outside of the black layer and the white layer. The black layer is the base layer for spraying black ink on the PET transparent film, and the white layer is the base layer on the PET transparent film. The base layer of spraying white ink on the PET transparent film, the thickness of described base material layer, adhesive layer and release layer are consistent, and the thickness of described base material layer is 4 microns, and described adhesive layer is used for bonding base material layer and Release layer.

Embodiment 2

[0034] This embodiment is based on embodiment 1, and the difference with embodiment 1 is: the thickness of described substrate layer is 6 microns, wherein the thickness ratio of black layer and white layer is 1:2, and promptly black layer thickness is 2 microns, white The layer thickness was 4 microns.

Embodiment 3

[0036] This embodiment is based on embodiment 1, and the difference with embodiment 1 is: the thickness of described substrate layer is 8 microns, wherein the thickness ratio of black layer and white layer is 1:1.5, and promptly black layer thickness is 3.2 microns, and white layer thickness is 3.2 microns. The layer thickness was 4.8 microns.

Abstract

The invention discloses a double-sided adhesive light shading adhesive tape and a preparation method thereof. The light shading adhesive tape comprises a substrate layer, adhesive layers arranged on both sides of the substrate layer, and releasing layers attached to the adhesive layers. The substrate layer comprises a black layer and a white layer, and the 2 adhesive layers are arranged on the outer side of the black layer and the outer side of the white layer respectively. The substrate layer is set into the black layer and the white layer, and the light shading adhesive tape has both light shading property and reflectivity, so that the light shading adhesive tape has good light shading performance; therefore, the problem of poor light shading performance of a conventional light shading adhesive tape is solved.

Description

technical field [0001] The invention relates to the technical field of light-shielding tapes, in particular to a double-sided adhesive light-shielding tape and a preparation method thereof. Background technique [0002] Liquid crystal displays (LCDs) are widely used in terminal display devices of various sizes due to their light weight, small volume, and thin thickness. LCD is a passive light-emitting display, that is, the display panel itself does not emit light, and needs to use the backlight module to emit light to realize image display. When laminating the display panel and the backlight module, in order to avoid light leakage, the display panel and the backlight module are usually bonded with a light-shielding tape. [0003] The light-shielding performance of the existing light-shielding adhesive tape is relatively poor. Contents of the invention [0004] The object of the present invention is to provide a double-sided adhesive light-shielding adhesive tape to solve...
