Adhesive belt with electromagnetic wave shielding function

Abstract

The invention discloses an adhesive belt with an electromagnetic wave shielding function. The adhesive belt comprises a surface layer, a middle layer and a gluing layer, wherein the surface layer is a PVC film, and the middle layer is an electromagnetic wave shielding film which comprises the following main components by weight percent: 40%-50% of activated carbon particles, 15%-25% of nano-silver particles, 30%-40% of a synthetic resin and the balance of an additive; and the surface layer and the middle layer can be adhered and connected through hot-press treatment, and the gluing layer is coated on the other combining surface of the middle layer. The adhesive belt with the electromagnetic wave shielding function provided by the invention has the advantages that the adhesive belt is in a multi-layer composite structure design, the surface layer has the good waterproof and stain resistance properties, the middle surface has the unique electromagnetic wave shielding function and can effectively obstruct the damage of the electromagnetic wave on a human body and the influence of the electromagnetic wave on periphery electronic devices, and the adhesive property of the gluing layer is stable; and the bonding strength of each layer of the adhesive belt is high, the property of the adhesive belt is good, and the application range of the adhesive belt is effectively improved.

Description

technical field [0001] The invention belongs to an adhesive tape, in particular to a novel adhesive tape with electromagnetic wave shielding function, and belongs to the technical field of adhesive tapes. Background technique [0002] As early as 1928, American Richard Drew invented scotch tape in St. Paul, Minnesota. Adhesive tapes can be classified according to their functions: high-temperature tapes, double-sided tapes, insulating tapes, special tapes, pressure-sensitive tapes, die-cut tapes, etc. Tapes with different functions are suitable for different industry needs. Among them, shielding tape is also called anti-static tape. The tape has the advantages of heat preservation, heat insulation, fire prevention, and cold resistance. It can eliminate electromagnetic radiation, isolate the harm of electromagnetic waves to the human body and the impact on surrounding electronic components. Computer peripheral wire and transformer manufacturing and pipeline seams of electrica...

Problems solved by technology

[0003] The current tape with electromagnetic wave shielding function refers to copper foil tape. The tape has stable performance and is easy to use, but the preparation process of the tape is relatively complicated, the cost is too high, and the tensile strength of the tape is not ideal, and the waterproof and stain resistance are relatively weak. Poor, limited scope of application, poor practicability
