[0026] Please refer to Figs. 1-3 An electromagnetic shielding camouflage net, comprising a camouflage net frame 1, a structure net frame 2 and an electromagnetic shielding cloth 5, the camouflage net frame 1 is set as a camouflage oxford cloth. The structure net frame 2 is set as a rope net with a 5cm*5cm grid. The electromagnetic shielding cloth 5 is set as a plain conductive cloth, and its thickness is set to 0.08mm, the shielding effectiveness is set to 70~90db, and the surface resistance is less than or equal to 0.05Ω.

[0027] The camouflage net frame 1, the structural net frame 2 and the electromagnetic shielding cloth 5 are arranged in sequence, and the four peripheral edges of the camouflage net frame 1, the structural net frame 2 and the electromagnetic shielding cloth 5 are fixedly provided with double wrapping edges 3 for wrapping. The camouflage net frame 1, the structural net frame 2 and the electromagnetic shielding cloth 5 are arranged in sequence in upper and lower layers, and the edges of the three are wrapped by wrapping the edges through the double wrapping edges 3, and then the camouflage net frame 1, the structural net frame 2 and the electromagnetic shielding cloth 5 are installed and used through the installation assembly, and the signal is shielded through the electromagnetic shielding cloth 5.

[0028] The outer part of the double wrapping edge 3 is integrally connected with the installation assembly, the installation assembly includes an installation rope 4 integrally connected to the outer side of the four corners of the double wrapping edge 3, and the installation rope 4 is fixed to the outer side of the four corners of the double wrapping edge 3, so that the whole electromagnetic shielding camouflage net can be fixed and installed for use through the installation rope 4. The installation assembly further includes a limiting piece 7 integrally connected to the inner side of the four corners of the double wrapping edge 3, and the limiting piece 7 is fixed to the inner side of the four corners of the double wrapping edge 3, so that the whole electromagnetic shielding camouflage net can be hung at four fixed positions for use through the limiting piece 7, for example, hung on a column similar to a wooden pile through the limiting piece 7, so that quick installation can be achieved. The inner side of the four corners of the double wrapping edge 3 is connected in a diagonal line with a traction fixing rope 6, so that the electromagnetic shielding camouflage net can be prevented from being torn and the stability of the structure can be increased when the whole electromagnetic shielding camouflage net is installed and used through the traction fixing rope 6.

[0029] Further, in the embodiment, the electromagnetic shielding cloth 5 is composed of a polyester fiber layer 501, a conductive base layer 502, a copper layer 503 and a nickel layer 504, and the polyester fiber layer 501, the conductive base layer 502, the copper layer 503 and the nickel layer 504 are sequentially stacked. The electromagnetic shielding cloth 5 takes the polyester fiber layer 501 as a base material, first chemically deposits or physically transfers metal nickel to the polyester fiber layer 501, then platinums a high-conductivity copper layer 503 on the nickel, and then electroplates an anti-oxidation and anti-corrosion nickel metal on the copper layer 503 to form a nickel layer 504. The copper and nickel provide excellent conductivity and good electromagnetic shielding effect, and the copper layer 503, the nickel layer 504 and the polyester fiber layer 501 form a conductive base layer 502.

[0030] The working principle of the electromagnetic shielding camouflage net is as follows:

[0031] (1) Based on the following synergistic effects: Copper, the golden partner of conductivity, is a metal with conductivity second only to silver (electrical conductivity about 59.6 MS / m), which can quickly conduct current; although the electrical conductivity of nickel is relatively low (about 14.3 MS / m), it can enhance the adhesion of copper and the base material as an intermediate layer, and optimize the overall conductivity efficiency through interface electron coupling.

[0032] (2) With a double protection mechanism:

[0033] Inner layer nickel layer: form nanoscale metal anchor points on the surface of polyester fibers by chemical deposition, solve the interface bonding problem of high molecular substrate and metal, prevent the peeling of the plated layer.

[0034] Outer layer nickel layer: wrap the copper layer, resist oxygen and moisture in the air (copper is easy to oxidize in humidity > 60% environment), keep the conductivity stable for > 5 years.

[0035] (3) Synergistic enhancement of electromagnetic shielding:

[0036] Copper layer: reflectivity > 99% to high frequency electromagnetic waves (> 300MHz) due to high free electron density , can respond to alternating electromagnetic field instantly.

[0037] Nickel layer: performs better in low frequency band (< 100kHz), its ferromagnetism (Curie temperature 358℃) can absorb electromagnetic waves through magnetic loss, making up for the shielding short board of copper in low frequency band.

[0038] The structure is optimized and designed as a "nickel-copper-nickel" sandwich structure, which not only ensures the flexibility of the substrate (bending radius < 5mm), but also forms a Cu-Ni alloy transition layer through intermetallic diffusion, reducing the interface resistance to .

[0039] This material combination performs well in electromagnetic shielding efficiency (SE) test, at 1GHz frequency, SE can reach more than 85dB, equivalent to attenuating the electromagnetic wave energy to times the original intensity, meeting the stringent requirements of electromagnetic compatibility in military, aerospace and other fields.
