Description

Technical Field

[0001] The utility model relates to the technical field of copper foil tape equipment, in particular to a wear-resistant double-conductor copper foil tape. Background Art

[0002] Copper foil tape is a metal tape, mainly used for electromagnetic shielding. Electromagnetic shielding is divided into electrical signal shielding and magnetic signal shielding. Electrical signal shielding mainly relies on the excellent conductivity of copper itself, while magnetic shielding requires "nickel" to achieve the effect of magnetic shielding. At present, some problems are still exposed in the use of the tape; the shielding effect of the current copper foil tape is still not ideal when used, and the copper foil tape is easily damaged by external force, resulting in low shielding effect of the tape; in view of the problems exposed in the use of the current tape, it is necessary to improve and optimize the structure of the tape.

[0003] Patent No. CN209493522U discloses a double-sided conductive copper foil tape, comprising a tape body, a tear strip 2 mounted on the left end of the tape body, a left strip mounted on the left end of the tear strip 2, the left strip connected to the tape body via the tear strip 2, a tear strip 1 mounted on the right end of the tear strip 1, the right strip connected to the tape body via the tear strip 1, a triangular corner formed on the left end and the right end of the left strip, and a rounded corner formed on the right end of the right strip. Compared with the prior art, the present invention has the following beneficial effects: good dustproof effect, improved aesthetics, and convenient length measurement. Existing double-sided conductive copper foil tapes have poor adhesion performance, and some contact surfaces to be adhered are not flat, resulting in the double-sided conductive copper foil tape not being able to adhere as tightly as plastic tape, easily bulging and flanging, and low adhesion efficiency. To this end, we propose a wear-resistant double-conductor copper foil tape. Utility Model Content

[0004] The purpose of the utility model is to provide a wear-resistant double-conductor copper foil tape to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a wear-resistant double-conductor copper foil tape, comprising a tape body, wherein the tape body comprises a base fabric layer, a connecting layer, a protective layer, an ink layer, a reinforcing layer and a wear-resistant layer, the tape body comprising at least one copper foil layer, the lower side of the base fabric layer being connected to the release layer via an adhesive layer, the adhesive layer comprising a plurality of adhesive blocks distributed at equal distances, grooves being provided between adjacent adhesive blocks, a plurality of protrusions of different heights being provided on the surface of the adhesive block, and a rib being provided on the outer side of the adhesive block.

[0006] In the above solution, the release layer is release paper.

[0007] In the above solution, a plurality of reinforcement blocks are provided in the reinforcement layer, and heat dissipation channels are provided on the sides of the reinforcement blocks.

[0008] In the above solution, the base fabric layer, connecting layer, protective layer, ink layer, reinforcement layer and wear-resistant layer are pressed into an integrated structure.

[0009] In the above solution, the thickness of the rib is slightly greater than the adhesive block, and a waterproof film is provided on the rib.

[0010] In the above solution, the reinforcing layer is a PET layer.

[0011] In the above solution, the protective layer is filled with a plurality of flame retardant particles.

[0012] Compared with the prior art, the beneficial effects of the present invention are: the wear-resistant double-conductor copper foil tape has a simple and reasonable structural design and is highly practical.

[0013] The tape's main structure, consisting of multiple layers of base fabric, connecting layer, protective layer, ink layer, reinforcement layer, wear-resistant layer, and copper foil, enhances its strength and toughness, ensuring its effectiveness and achieving wear resistance and light-shielding properties. The adhesive layer comprises multiple equally spaced adhesive blocks with undulating protrusions, enabling the adhesive layer to effectively adhere to structures with surface defects and allow the tape to be adhered to uneven surfaces, enhancing its adsorption properties and improving its adhesion efficiency. The sidewall design prevents dust accumulation on the sides of the tape, further improving its adsorption stability. Grooves on the sides of the adhesive blocks prevent deformation. When the tape body is bent, the adhesive blocks squeeze each other to form a bond and support effect, preventing excessive deformation and ensuring its overall stability. Flame-retardant particles distributed within the protective layer prevent the special-treated layer from spontaneous combustion due to excessive surface temperature in high temperatures for extended periods, reducing the risk of spontaneous combustion.
