Description

Technical Field

[0001] This utility model relates to the field of adhesive tape technology, specifically a new type of antistatic light-shielding adhesive tape. Background Technology

[0002] In the computer manufacturing process, tape is often used to fix circuit boards and modules. Some computer monitors use tape around the screen or at the bottom to fix the screen in place, ensuring that the screen will not shake or shift during use, thereby improving stability and safety.

[0003] Antistatic light-shielding tape uses PTE film as the base material. Black paint is printed on one side of the PTE film for light-shielding treatment, and then adhesive is coated on the other side of the PTE film.

[0004] A search revealed that patent application number 202222083866.6 discloses a light-shielding and anti-static tape for computers, comprising a tape body. The tape body includes a first anti-static layer, a light-shielding layer, a second anti-static layer, a pressure-sensitive adhesive layer, and a release film. The first anti-static layer, the light-shielding layer, the second anti-static layer, the pressure-sensitive adhesive layer, and the release film are stacked together sequentially from top to bottom. The first and second anti-static layers are made of the same material, both being natural anti-static rubber. The first anti-static layer, the light-shielding layer, and the second anti-static layer are fixed together by adhesive bonding. The release film is made of PET material, and the pressure-sensitive adhesive layer is made of silicone-modified rubber.

[0005] Although the computer light-shielding and anti-static tape has excellent light-shielding and anti-static properties due to the addition of light-shielding and anti-static layers, it cannot shield the electromagnetic waves in the fixed circuits, which can easily interfere with the computer's operation.

[0006] Therefore, we propose a new type of antistatic light-shielding tape. Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model provides a novel antistatic light-shielding tape, which solves the problem that existing devices cannot shield electromagnetic waves in their fixed circuits, and that electromagnetic waves can easily interfere with computer operation.

[0008] To achieve the above objectives, this utility model is implemented through the following technical solution: a novel antistatic light-shielding tape, comprising a tape body, wherein the tape body comprises, from top to bottom, a first antistatic layer, a light-shielding layer, a second antistatic layer and an adhesive layer, wherein the light-shielding layer is bonded to the bottom surface of the first antistatic layer;

[0009] A first electromagnetic shielding layer is disposed between the light-shielding layer and the second antistatic layer, a second electromagnetic shielding layer is disposed between the second antistatic layer and the adhesive layer, and a base layer is disposed between the second electromagnetic shielding layer and the adhesive layer. The light-shielding layer, the first electromagnetic shielding layer and the second antistatic layer are fixed together by adhesive bonding, and the second antistatic layer, the second electromagnetic shielding layer, the base layer and the adhesive layer are fixed together by adhesive bonding. A release film is attached to the bottom surface of the adhesive layer.

[0010] Preferably, the first electromagnetic shielding layer is made of copper foil, and the second electromagnetic shielding layer is made of aluminum foil Mylar. Copper foil has good conductivity and can not only shield electromagnetic interference but also enhance signals. Aluminum foil Mylar is made of soft aluminum foil and polyester film composite, which can shield electromagnetic waves in the circuit.

[0011] Preferably, the base layer is made of PTE film, and both the top and bottom surfaces of the base layer are rough and uneven. The rough and uneven surface of the base layer can make the adhesive layer and the second electromagnetic shielding layer more stably bonded to the top and bottom surfaces of the base layer.

[0012] Preferably, the release film has a cutting line in the middle, and four easy-tear tabs are fixedly connected to the left and right sides of the release film, which are symmetrically distributed about the cutting line. The cutting line makes it easy to tear the release film into two parts, and the easy-tear tabs make it easy to peel the cutting line off from the adhesive layer.

[0013] This utility model provides a novel antistatic light-shielding tape. It has the following beneficial effects:

[0014] 1. This new type of antistatic light-shielding tape, through the setting of the first electromagnetic shielding layer and the second electromagnetic shielding layer, can shield electromagnetic interference at the wire harness connection. Through the first antistatic layer, the light-shielding layer and the second antistatic layer, the tape body has excellent light-shielding and antistatic properties, which helps to avoid electromagnetic waves in the circuit from interfering with the computer operation. It solves the problem that existing devices cannot shield electromagnetic waves in their fixed circuits, and electromagnetic waves easily interfere with the computer operation.

[0015] 2. This new type of antistatic light-blocking tape features easy-tear tabs, making it convenient to peel the release film off the bottom of the adhesive layer. The cutting lines allow the release film to be peeled off from the bottom of the adhesive layer in two steps, preventing the two sides of the tape from sticking together. It is simple and convenient to use. Attached Figure Description
