Description

Technical Field

[0001] The utility model relates to the technical field of adhesive tapes, in particular to an antistatic light-shielding adhesive tape. Background Art

[0002] Antistatic shading tape is a tape with antistatic properties, usually used to prevent static electricity from damaging sensitive equipment or materials. This tape is usually made of antistatic material and can effectively absorb or disperse static electricity, thereby reducing or avoiding the occurrence of electrostatic discharge. In addition, shading tape also has a shading function that can block the penetration of light. It is suitable for occasions where photosensitive materials need to be protected or light needs to be controlled in specific environments. This tape is often used in electronic product manufacturing, medical equipment, aerospace and other fields to ensure the stability and reliability of the equipment.

[0003] An existing patent (publication number: CN206721094U) proposes a tape, the key points of its technical solution are that the tape body includes a substrate layer and a primer layer, the primer layer is a silicone pressure-sensitive adhesive, the thickness of the primer layer is 0.055-0.065mm, the substrate layer includes a first anti-wear rope group and a second anti-wear rope group, the first anti-wear rope group is arranged adjacent to each other, the second anti-wear rope group is arranged adjacent to each other, and the first anti-wear rope group and the second anti-wear rope group are interwoven and connected. The purpose of this utility model is to provide a tensile-resistant tape with a long service life.

[0004] However, existing tapes usually have poor anti-static and light-shielding effects. In static-sensitive environments, such as electronic production lines or medical equipment manufacturing processes, static electricity can damage electronic components or equipment. If the tape cannot effectively prevent the generation or conduction of static electricity, these devices are susceptible to static damage. In addition, in a working environment where photosensitive materials need to be protected, if the light-shielding effect of the tape is poor, the photosensitive materials will be exposed to excessive light, thereby reducing their quality or causing damage. Therefore, the utility model proposes an anti-static light-shielding tape to solve the above problems. Utility Model Content
