Embodiment 1

[0038] The following steps are used to make nickel-plated carbon fiber cloth with electromagnetic shielding performance:

[0039] Step 1. Decontamination on the surface of carbon fiber cloth: The pollutants and active agents adsorbed on the surface of carbon fiber cloth are removed by ion bombardment. The travel speed of carbon fiber cloth in the decontamination equipment is 90m / h, and the active agent on the surface of carbon fiber cloth is vaporized , according to the amount of vaporized gas to control the degree of treatment of the dirt on the surface of the carbon fiber cloth, the carbon fiber cloth is T300-3K twill carbon fiber cloth.

[0040]Step 2. Magnetron sputtering nickel plating on the surface of carbon fiber cloth: use magnetron sputtering technology to vacuum nickel-plate the surface of carbon fiber cloth after step 1, and evenly spray nickel ions in the form of nanoparticles to the surface of carbon fiber cloth , form a nickel-plated carbon fiber cloth, and the ...

Embodiment 2

[0046] The following steps are used to make nickel-plated carbon fiber cloth with electromagnetic shielding performance:

[0047] Step 1. Decontamination on the surface of carbon fiber cloth: the pollutants and active agents adsorbed on the surface of carbon fiber cloth are removed by ion bombardment. The travel speed of carbon fiber cloth in the decontamination equipment is 100m / h, and the active agent on the surface of carbon fiber cloth is vaporized , according to the amount of vaporized gas to control the degree of treatment of the dirt on the surface of the carbon fiber cloth, the carbon fiber cloth is T300-3K twill carbon fiber cloth.

[0048] Step 2. Magnetron sputtering nickel plating on the surface of carbon fiber cloth: use magnetron sputtering technology to vacuum nickel-plate the surface of carbon fiber cloth after step 1, and evenly spray nickel ions in the form of nanoparticles to the surface of carbon fiber cloth , form a nickel-plated carbon fiber cloth, and th...

Embodiment 3

[0064] Such as figure 1 As shown, compared with Example 1, the secondary nickel-plated carbon fiber cloth treated in step five is pressed with resin to form a nickel-plated carbon fiber plate with electromagnetic shielding performance, and the resin layer covers the entire surface of the secondary nickel-plated carbon fiber cloth. Other steps are the same as in Example 1 to make a nickel-plated carbon fiber plate.

Abstract

The invention discloses a method for producing a nickel-plated carbon fiber board having electromagnetic shielding property. The method includes the steps: step 1, carbon fiber cloth surface treatment; step 2, magnetron sputtering nickel plating of the carbon fiber cloth surface; step 3, copper electroplating of the carbon fiber cloth surface; step 4, nickel electroplating of the carbon fiber cloth surface; step 5, drying; and step 6, board pressing. The nickel-plated carbon fiber plate has the electromagnetic shielding effectiveness of more than 40 dB in a 150 kHz-18 GHz electromagnetic field, and the stability of the electromagnetic shielding effect of carbon fiber cloth can be effectively improved through the nickel-copper-nickel three-plating-layer structure design; and through the composite material molding, a resin layer on the nickel-plated carbon fiber surface improves the corrosion resistance of the product.

Description

technical field [0001] The invention belongs to the technical field of electromagnetic shielding, and in particular relates to a method for manufacturing a nickel-plated carbon fiber plate with electromagnetic shielding performance. Background technique [0002] Electromagnetic shielding cabinets and cabinets are common products in the field of electromagnetic shielding. However, electromagnetic shielding cabinets and cabinets are made of plates with electromagnetic shielding. At present, their manufacturing process is complicated. First of all, in order to ensure the strength of the car body, the board of the car body generally adopts a "sandwich" structure made of metal skin and foam core, and a metal frame is set in the middle for supporting and strengthening; secondly, in order to ensure the shielding effect, the board's Conductive aluminum foil is used for the overlapping joints. When installing corner aluminum, it is necessary to control the amount of glue used and the...
