Description

Technical Field

[0001] The utility model relates to the technical field of conductive tape equipment, and particularly relates to an aluminum foil conductive tape with an antioxidant coating. Background Technique

[0002] The conductive cloth tape is made of conductive cloth, and its characteristic is that it adds the "adhesive" characteristic on the basis of the conductive cloth. Its important characteristics can refer to the entry - conductive cloth. Generally in the industry, the "adhesive" expected is the conductive adhesive, that is, the one with the "nickel" component, in order to achieve the effect of magnetic shielding. However, there are also cases where non - conductive adhesives such as ordinary acrylic adhesives or hot - melt adhesives are used, and the purpose is to make the conductive cloth have good adhesiveness. The conductive cloth material is on the polyester fiber, first electroplated with metallic nickel, then plated with a highly conductive copper layer on the nickel, and then electroplated with nickel metal for anti - oxidation and anti - corrosion on the copper layer. The combination of copper and nickel provides excellent electrical conductivity and good electromagnetic shielding effect, and the shielding range is from 100K to 3GHz. The conductive cloth tape is applicable to various electronic and electrical products such as computers, mobile phones, wires, and cables, mainly to shield or isolate the interference of electromagnetic waves or radio waves during high - frequency transmission. However, during the use of the tape, it may be severely deformed due to bending, reducing the bonding effect on the tape surface, damaging the anti - oxidation layer on the tape surface, resulting in a decline in the antioxidant performance and magnetic shielding performance of the tape, and thus leading to a deterioration in electrical conductivity. Therefore, we propose an aluminum foil conductive tape with an antioxidant coating. Content of the Utility Model

[0015] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0016] Please refer to Figure 1-2, the present utility model provides a technical solution: an aluminum foil conductive tape with an antioxidant coating, including a conductive tape main body 1. The conductive tape main body 1 includes a conductive cloth base layer 11, a conductive adhesive layer 12, an electromagnetic shielding film layer 13, an antistatic plating layer 14, and an antioxidant coating 15. The conductive cloth base layer 11, the conductive adhesive layer 12, the electromagnetic shielding film layer 13, the antistatic plating layer 14, and the antioxidant coating 15 are connected through an adhesive layer 17. A release film layer 16 is provided on the upper side of the conductive tape main body 1. A deformation prevention layer 2 is provided on the upper side of the antioxidant coating 15. The deformation prevention layer 2 includes a plurality of elastic strips 21, and grooves 22 are formed between adjacent elastic strips 21. The antioxidant coating 15 is made of a synthetic silicate modified solution as a film-forming substance, and then antioxidant titanium metal micropowder is added, having good antioxidant effect.

[0017] The electromagnetic shielding film layer 13 plays a magnetic shielding effect during the conduction process of the conductive adhesive layer. The antioxidant coating 15 has better contact with the electromagnetic shielding film layer 13, and the antistatic plating layer 14 also plays an antistatic role; by providing the deformation prevention layer 2 on the antioxidant coating 15, when the conductive cloth tape main body is bent, adjacent elastic strips 21 form a supporting effect when squeezing each other, preventing the conductive cloth tape main body from deforming excessively, ensuring the overall stability of the conductive tape main body 1, and effectively enhancing the antioxidant performance of the conductive tape main body 1.

[0018] In the above solution, an information label 19 is provided on the release film layer 16. Through the information label 19, information can be prominently prompted to the user.

[0019] In the above solution, reinforcing strips 18 are provided in the adhesive layer 17. The reinforcing strips 18 are made of soft PVC materials, and the setting of the reinforcing strips 18 further improves the structural strength and stability of the conductive tape main body 1.

[0020] In the above solution, the thickness of the conductive cloth base layer 11 is 0.10 mm.

[0021] In the above solution, the thickness of the conductive adhesive layer 12 is 0.05 mm.

[0022] In the above solution, the adhesive layer 17 is an acrylic adhesive layer. Through the adhesive layer 17, the electric cloth base layer 11, the conductive adhesive layer 12, the electromagnetic shielding film layer 13, the antistatic plating layer 14, and the antioxidant coating 15 are stably connected through the adhesive layer 17.

[0023] In the above solution, the thickness of the electromagnetic shielding film layer 13 is 0.005 mm. The thickness of the shielding layer should not be too thin, otherwise the shielding effect on magnetic signals will be reduced. The thickness of the shielding layer should not be too thick either, otherwise the cost of the conductive tape will increase. After actual tests, when the thickness of the electromagnetic shielding film layer 13 is 0.005 mm, costs can be saved while ensuring good magnetic signal shielding.

[0024] The anti-static coating layer 14 uses a polyethylene terephthalate film. After testing, when the thickness of the anti-static coating layer 14 is 0.008 mm, good anti-static effects can be achieved at a relatively low cost.

[0025] Working principle:

[0026] When using this aluminum foil conductive tape with an antioxidant coating, first tear off the release film layer 16, and then attach the side of the antioxidant coating 15 of the conductive tape main body 1 to the corresponding electronic component. The electromagnetic shielding film layer 13 provides a magnetic shielding effect during the conduction process of the conductive adhesive layer. The antioxidant coating 15 has better contact with the electromagnetic shielding film layer 13, and the anti-static coating layer 14 also plays an anti-static role. Through the anti-deformation layer 2 provided on the antioxidant coating 15, when the conductive cloth tape main body is bent, the adjacent elastic strips 21 are pressed against each other to form a supporting effect, preventing the conductive cloth tape main body from deforming excessively, ensuring the overall stability of the conductive tape main body 1, and effectively enhancing the magnetic shielding, anti-static, and antioxidant properties of the conductive tape main body 1.
