Description

Technical Field

[0001] The utility model relates to the technical field of light-shielding tapes, in particular to a black-edge composite substrate light-shielding tape. Background Technique

[0002] A light-shielding tape is a special tape with a light-shielding function. In order to provide physical support and structural stability for the light-shielding tape, so as to ensure that the tape has a certain strength and durability, people generally use a composite substrate to make the light-shielding tape. At the same time, in order to prevent light leakage at the edge of the composite substrate light-shielding tape, a black edge is added to the edge of the composite substrate light-shielding tape, thus making a black-edge composite substrate light-shielding tape.

[0003] However, in the prior art, when the existing black-edge composite substrate light-shielding tape is in use, although it can effectively block the transmission of light and provide a good light-shielding effect, it does not have the function of improving the bonding strength between the black edge and the composite substrate light-shielding tape. That is, when the black-edge composite substrate light-shielding tape is used in an environment with a relatively high humidity, the bonding performance between the black edge and the composite substrate is likely to decline, resulting in the black edge falling off from the composite substrate, and further causing light leakage at the edge of the black-edge composite substrate light-shielding tape, which not only reduces the use effect of the black-edge composite substrate light-shielding tape, but also reduces the use efficiency of the black-edge composite substrate light-shielding tape.

[0004] Therefore, we propose a black-edge composite substrate light-shielding tape to solve the technical problems raised in the background technique. Content of the Utility Model

[0005] The purpose of the utility model is to solve the problem that the existing black-edge composite substrate light-shielding tape in the prior art does not have the function of improving the bonding strength between the black edge and the composite substrate light-shielding tape when in use. That is, when the black-edge composite substrate light-shielding tape is used in an environment with a relatively high humidity, the bonding performance between the black edge and the composite substrate is likely to decline, resulting in the black edge falling off from the composite substrate, and further causing light leakage at the edge of the black-edge composite substrate light-shielding tape, which not only reduces the use effect of the black-edge composite substrate light-shielding tape, but also reduces the use efficiency of the black-edge composite substrate light-shielding tape, and to propose a black-edge composite substrate light-shielding tape.

[0006] To achieve the above object, the present utility model adopts the following technical solutions: A black edge-banded composite substrate light-shielding tape, comprising a tape body, wherein the tape body includes a composite substrate layer, and anti-tearing layers are provided on both the top and the bottom of the composite substrate layer. A wear-resistant layer is provided on the top of one of the anti-tearing layers, and a light-shielding layer is provided on the bottom of the other anti-tearing layer. An adhesive layer is provided on the bottom of the light-shielding layer, and edge-banding layers are provided on both sides of the wear-resistant layer.

[0007] Preferably, the opposite sides of the two edge-banding layers are respectively adhered to both sides of the composite substrate layer, and the opposite sides of the two edge-banding layers are respectively adhered to both sides of the light-shielding layer.

[0008] Preferably, both ends of each anti-tearing layer are respectively tightly wrapped and fused on the two edge-banding layers, and the bottoms of the two edge-banding layers are adhered to the top of the adhesive layer.

[0009] Preferably, one side of one of the edge-banding layers is in the same plane as one side of the adhesive layer, and the side of the other edge-banding layer away from one of the edge-banding layers is in the same plane as the other side of the adhesive layer.

[0010] Preferably, the composite substrate layer includes a low-temperature resistant layer, and an anti-corrosion layer is provided on the top of the low-temperature resistant layer.

[0011] Preferably, an anti-tensile layer is provided on the top of the anti-corrosion layer, and a high-temperature resistant layer is provided on the top of the anti-tensile layer.

[0012] Preferably, an anti-aging layer is provided on the top of the high-temperature resistant layer, and a waterproof layer is provided on the top of the anti-aging layer.

[0013] Compared with the prior art, the advantages and positive effects of the present utility model are as follows.

[0014] 1. In the present utility model, by providing the tape body, the black edge-banded composite substrate light-shielding tape can have the function of improving the bonding strength between the black edge and the composite substrate light-shielding tape when in use. That is, when the black edge-banded composite substrate light-shielding tape is used in an environment with high humidity, it is not easy to have a decrease in the bonding performance between the black edge and the composite substrate, thus avoiding the black edge from peeling off from the composite substrate, and further ensuring that there is no light leakage at the edge of the black edge-banded composite substrate light-shielding tape. This not only improves the use effect of the black edge-banded composite substrate light-shielding tape but also improves the use efficiency of the black edge-banded composite substrate light-shielding tape. Under the action of the anti-tearing layer, the bonding strength between the edge-banding layer and the wear-resistant layer can be increased, and under the action of the wear-resistant layer, the wear resistance strength of the black edge-banded composite substrate light-shielding tape can be increased.

[0015] 2. In the present utility model, under the action of the high-temperature resistant layer, the black edge-bonded composite substrate light-shielding tape can still maintain stable performance in a high-temperature environment. Under the action of the waterproof layer, when the black edge-bonded composite substrate light-shielding tape is used, it can prevent moisture from penetrating into the tape, thereby affecting the adhesion effect.
