preparation example Construction

[0024] The present invention also provides a kind of preparation method of above-mentioned light-duty metal wave-proof cover, and this preparation method comprises:

[0025] 1) After the aluminum alloy raw material is heat-treated at 500°C-550°C, it is vacuum degassed, vacuum hot-pressed, hot-extruded with a mold, cooled, and then cold-pressed to form an aluminum alloy wire;

[0026] 2) subjecting the aluminum alloy wire to activation treatment, followed by copper plating treatment and nickel plating treatment to obtain nickel-plated copper aluminum alloy wire;

[0027] 3) The nickel-plated copper-aluminum alloy wires are paralleled, and then braided on a double-rotary braiding machine to obtain a light-weight metal anti-wave sleeve.

[0028] In the above preparation method, the mode of activation treatment can be selected in a wide range, but in order to further improve the activation effect, preferably, the activation treatment is dipped in 4-6% by weight of dilute sulfuric ...

Embodiment 1

[0033] 1) After the aluminum alloy raw material is heat-treated at 530°C, it is vacuum degassed, vacuum hot-pressed, hot-extruded with a mold, cooled, and then cold-pressed to form an aluminum alloy wire;

[0034] 2) The aluminum alloy wire is subjected to activation treatment for 25 minutes (impregnated with 5% by weight of dilute sulfuric acid), followed by copper plating treatment and nickel plating treatment to obtain a nickel-plated copper aluminum alloy wire with a diameter of 0.12 mm, and the thickness of the copper plating layer is 0.25 mm. μm, the thickness of nickel plating layer is 0.8μm;

[0035] 3) Parallel the nickel-plated copper-aluminum alloy wires (by a doubling machine), and then weave them on a double-rotary braiding machine to obtain a light metal anti-wave sheath with a weaving density of 95%.

Embodiment 2

[0037] 1) After the aluminum alloy raw material is heat-treated at 500°C, it is vacuum degassed, vacuum hot-pressed, hot-extruded with a mold, cooled, and then cold-pressed to form an aluminum alloy wire;

[0038] 2) The aluminum alloy wire was activated for 20 minutes (impregnated with 5% by weight of dilute sulfuric acid), followed by copper plating and nickel plating in order to obtain a nickel-plated copper-aluminum alloy wire with a diameter of 0.10 mm, and the thickness of the copper plating layer was 0.2 mm. μm, the thickness of nickel plating layer is 0.6μm;

[0039] 3) Parallel the nickel-plated copper-aluminum alloy wires (by a doubling machine), and then weave them on a double-rotary braiding machine to obtain a light-weight metal anti-wave sheath with a weaving density of 98%.

Abstract

The invention discloses a light metal wave-proof sleeve and a preparation method thereof. The light metal wave-proof sleeve is formed by weaving nickel-plated copper-aluminum alloy wires, each nickel-plated copper-aluminum alloy wire sequentially comprises an aluminum alloy wire body, a copper-plated layer and a nickel-plated layer from inside to outside, the thickness of each copper-plated layeris 0.2-0.3 micrometer, and the thickness of each nickel-plated layer is 0.6-1.0 micrometer; the nickel-copper-plated aluminum alloy wire contains aluminum, copper, magnesium, silicon, zinc, manganese,lithium, titanium, vanadium, boron, nickel, chromium and rare earth metals in a weight ratio of (55-65): (8-12): (3-5): (2-4): (1-3): (1-3): (1-3): (1.5-2.5): (0.3-0.7): (0.4-0.8): (1.5-2.5): (1.2-1.6): (1.3-1.8). The light metal wave-proof sleeve has light weight and an excellent anti-electromagnetic shielding effect at the same time, and in addition, the preparation method has the advantages ofbeing easy and convenient to operate and easy to popularize.

Description

technical field [0001] The invention relates to a wave-proof cover, in particular to a light-weight metal wave-proof cover and a preparation method thereof. Background technique [0002] With the rapid development of the aviation industry, the replacement of aircraft is getting faster and faster. Not only are the functions of the aircraft itself more complex, but the aircraft must also adapt to the complex electromagnetic environment. Therefore, the design and verification of the electromagnetic environment effect of the aircraft has become an important aspect that affects the normal performance of the aircraft. [0003] The electromagnetic protection anti-wave cover starts from the coupling path of electromagnetic interference, and its use is an important technical means and measure to ensure electromagnetic compatibility between systems and to resist the complex electromagnetic environment outside. On the other hand, in order to improve the aircraft load and endurance, t...
