Problems solved by technology

[0003] However, with the popularization of 5G signals, the number of antennas required for 5G networks has increased significantly. The use of metal conductive materials will cause attenuation of wireless signals and may even shield wireless signals, resulting in interruption of signal transmission. Application of copper foil tape or conductive foam in the field of conducting static electricity
Therefore, it is necessary to develop a new type of material for eliminating static electricity, which can maintain a low resistance, but will not affect the transmission of antenna signals because the resistance value is too small, and will not cause static electricity to be unable to be exported because the resistance is too large
[0004] Chinese invention patent CN201911172970.9 discloses a high-viscosity antistatic tape, which achieves antistatic effect by adding an organic polymer antistatic agent, and has a high viscosity, but the organic polymer polythiophene is unstable. , it is easy to be reduced and the chemical properties change, so the conditions of the preparation process are more stringent
Chinese invention patent CN201910561384.7 discloses an antistatic tape and its preparation method. The antistatic purpose can be achieved by adding a metal material layer, but at the same time it will also cause shielding of electromagnetic signals and affect signal transmission.

Description

technical field [0001] The invention relates to a preparation method and application of a static electricity elimination adhesive tape, which is mainly applied to the field of static electricity elimination of electronic products, relates to C09J, and specifically relates to the field of adhesives. Background technique [0002] With the continuous updating and upgrading of electronic consumer products, the miniaturization of electronic consumer products leads to the complicated internal environment of electronic products. The internal electronic components will generate static electricity during the working process. The existence of a large amount of static electricity may affect the service life of electronic products. Therefore, static electricity needs to be drawn out during the assembly and connection of electronic components. Metal conductive materials are added to the medium. [0003] However, with the popularity of 5G signals, the number of antennas required for 5G n...
