Embodiment 1

[0039] This embodiment provides a black light-shielding conductive cloth tape, refer to figure 1 , along the thickness direction of the tape, it includes a release film layer, a conductive adhesive layer, a conductive fiber cloth layer and a black light-shielding layer. The adhesive strength (peeling force) of the conductive adhesive layer is 1200gf / 25mm, and the thickness of the conductive fiber cloth layer is 0.05mm. The concrete preparation method of this tape is as follows:

[0040] (1) In this embodiment, an ordinary silver-gray conductive fiber cloth is selected as the base material, and the surface of the silver-gray conductive fiber cloth is subjected to waterproof and anti-penetration treatment to obtain a conductive fiber cloth layer.

[0041](2) The surface of the conductive fiber cloth layer after surface treatment is coated with black ink again. The components of the black ink include 70% by weight of polyamideimide resin, 15% by weight of solvent toluene, 10% of...

Embodiment 2

[0050] This embodiment provides a black light-shielding conductive cloth tape, refer to figure 1 , along the thickness direction of the tape, it includes a release film layer, a conductive adhesive layer, a conductive fiber cloth layer and a black light-shielding layer. The black light-shielding conductive cloth tape of the present embodiment and the preparation method thereof are basically the same as those in Embodiment 1, and the main differences are:

[0051] 1) The adhesive strength of the conductive adhesive layer is 1700gf / 25mm, and the thickness of the conductive fiber cloth layer is 0.035mm.

[0052] In this example, the tape was placed in a normal temperature test for 24 hours, and a high and low temperature test of -40°C to 90°C for 7 days, and the test results were recorded in Table 1.

Abstract

The invention discloses a black shading conductive cloth adhesive tape and a preparation method thereof, and belongs to the technical field of adhesive tapes for electronic components. The adhesive tape sequentially comprises a conductive adhesive layer, a conductive fiber cloth layer and a black shading layer along the thickness direction of the adhesive tape, the bonding strength of the conductive adhesive layer is 800 gf / 25 mm to 2500 gf / 25 mm, and the thickness of the conductive fiber cloth layer is 0.03 mm to 0.1 mm. The conductive fiber cloth layer can be tightly attached to the surface of a product, so that the problem that the black shading conductive cloth adhesive tape tilts in a high-temperature and high-humidity environment is effectively solved, the service life of the adhesive tape is prolonged, and the product yield is increased.

Description

technical field [0001] The invention belongs to the technical field of tapes for electronic components, and more particularly relates to a black light-shielding conductive cloth tape and a preparation method thereof. Background technique [0002] The conductive cloths commonly used in the market are mostly gray conductive cloths. Fiber cloth is used as the base material, and electroplating is performed on the fiber cloth to make the fiber cloth conductive. Generally, it is mainly used in electronic products for conduction and grounding. effect. [0003] The defect of the black light-shielding conductive cloth at present is the warping phenomenon during the application process, which is encountered in the actual use process and is also a problem that is difficult to avoid in the prior art. For pictures of bad lift, please refer to the attached drawings of this application. Poor lift of the conductive cloth will lead to light leakage in the entire electronic product, and the ...
