Manufacturing process of adhesive tape with shielding film structure

Abstract

The invention belongs to the technical field of adhesive tape manufacturing, and particularly relates to a manufacturing process of an adhesive tape with a shielding film structure. The adhesive tapecomprises a shielding adhesive tape body, the shielding adhesive tape body comprises a nickel-plated polyester fiber cloth layer, an adhesive layer, release paper and an electromagnetic shielding layer, and the release paper, the adhesive layer, the nickel-plated polyester fiber cloth layer and the electromagnetic shielding layer are stacked in sequence. The electromagnetic shielding layer comprises pressing grooves and an anti-stretching high polymer material, the pressing grooves are pressed on the surface of the electromagnetic shielding layer through an embossing process, the anti-stretching high polymer material fills the pressing grooves pressed on the surface of the electromagnetic shielding layer, the electromagnetic shielding layer is a metal foil, and the metal foil is a copper foil or an aluminum foil. According to the manufacturing process of the adhesive tape with a shielding film structure, the electromagnetic shielding layer is wrapped by the PTC polymer conductive material with tensile resistance and conductivity in a segmentation manner, so that the transverse and longitudinal tensile resistance of the adhesive tape is greatly improved while the electromagnetic shielding effect of the adhesive tape is ensured, and the flexibility and crease resistance of the adhesive tape are improved.

Description

technical field [0001] The invention relates to the technical field of tape production, in particular to a tape production process with a shielding film structure. Background technique [0002] Tape is one of the tools commonly used for fixing and covering in daily life and work. According to its function, it can be divided into high-temperature tape, double-sided tape, shielding tape, pressure-sensitive tape and die-cutting tape. [0003] Shielding tape is a kind of metal foil or conductive cloth with conductive adhesive. Its conductive adhesive and conductive substrate form a complete conductor, which can be bonded to any metal surface to complete electrical lapping and electrical sealing of gaps. Shielding Conductive Tape is an affordable, easy-to-use shielding material. [0004] However, metal foil tapes have some inherent disadvantages: the presence of metal foil makes the overall softness and fit performance of the tape deviate, the transverse and longitudinal stretch...

Problems solved by technology

[0004] However, metal foil tapes have some inherent disadvantages: the presence of metal foil makes the overall softness and fit performance of the tape deviate, the transverse and longitudinal stretch resistance is weak, and it is easy to wrinkle during use, and it is easy to lose weight in the length and width directions. torn
