Preparation method of double-sided back adhesive conductive fabric

Abstract

The invention relates to a preparation method of a double-sided back adhesive conductive fabric, which comprises the following steps: pasting a conductive fabric on a first material belt, pasting a double-silicon release film on the conductive fabric, pasting a double-sided adhesive tape with double-sided collagen paper removed on the double-silicon release film, pasting a cover film, punching to the double-silicon release film for the second time, and removing the double-silicon release film to obtain the double-sided back adhesive conductive fabric. And obtaining the double-sided gum conductive fabric. Compared with the prior art that an upper-layer double-faced adhesive tape is directly adhered to the surface of the conductive cloth and cannot be processed in the processing process of the existing conductive cloth, the double-faced back adhesive conductive cloth can be obtained on the basis of not damaging other film materials by virtue of the fact that the double-silicon release film, the double-faced adhesive tape in contact with the double-silicon release film and the conductive cloth are free of stickiness.

[0002] Conductive cloth is based on fiber cloth (generally polyester fiber cloth), and after pre-treatment, an electroplated metal coating is applied to make it have metal characteristics and become conductive fiber cloth. Specifically, it can be divided into: nickel-plated conductive cloth, gold-plated conductive cloth, carbon-plated conductive cloth, and aluminum foil fiber composite cloth.

[0003] In the processing of existing conductive cloth, there is a problem that when the upper double-sided adhesive tape is directly attached to the conductive cloth surface, it will be directly adhered and cannot be processed, and double-sided adhesive tape conductive cloth cannot be obtained. Summary of the Invention

[0004] The purpose of the present invention is to provide a preparation method of conductive cloth with double-sided adhesive tape in order to overcome at least one of the defects existing in the above-mentioned prior art.

[0005] The purpose of the present invention can be achieved by the following technical solutions:

[0006] A preparation method of double-sided adhesive tape conductive cloth includes the following steps: attaching the conductive cloth to the first tape, then attaching a double-silicone release film to the conductive cloth, attaching a double-sided adhesive tape with the double-sided adhesive tape base paper removed to the double-silicone release film, then attaching a cover film, performing a second punching to the double-silicone release film, and removing the double-silicone release film to obtain double-sided adhesive tape conductive cloth.

[0007] Further, the preparation method of the first tape includes: attaching the non-release surface of the release film to the adhesive surface of the protective film, then attaching the double-sided adhesive tape to the release surface of the release film; discharging the waste double-sided adhesive tape base paper, attaching the cover film to the adhesive surface of the double-sided adhesive tape, and performing a first punching until the release film and the double-sided adhesive tape are cut off to obtain the first tape.

[0008] Further, the first tape includes a protective film, a release film, and a double-sided adhesive tape that are sequentially attached.

[0009] Further, the double-sided adhesive tape conductive cloth includes a cover film, a double-sided adhesive tape, a conductive cloth, a double-sided adhesive tape, a release film, and a protective film that are sequentially attached.

[0010] Further, the cross-sectional areas of the cover film, the double-sided adhesive tape, the conductive cloth, the double-sided adhesive tape, the release film, and the protective film are the same, and the projections coincide.

[0011] Further, the double-silicone release film is a release film with release surfaces on both sides.

[0012] Further, the double-silicone release film includes a PET substrate and silicone oil layers provided on both sides of the PET substrate.

[0013] Further, there is no adhesion between the release films on both sides of the double-silicon release film and the double-sided adhesive and conductive cloth in contact therewith.

[0014] Further, the conductive cloth includes a fiber cloth and a metal coating plated on the fiber cloth.

[0015] Further, the fiber cloth is a polyester fiber, and the metal coating is a gold coating, a silver coating, a nickel coating or a copper coating.

[0016] Compared with the existing conductive cloth, during the processing, if the upper double-sided adhesive is directly adhered to the surface of the conductive cloth, it will be directly stuck and impossible to process. With the help of the double-silicon release film of the present invention, there is no adhesion between the double-sided adhesive and the conductive cloth in contact therewith, and a double-sided adhesive conductive cloth can be obtained without damaging other film materials.
