[0022] Further, the present invention also provides a preparation method of graphene composite cable, such as image 3 As shown, it includes the following steps:

[0023] S10. Place the metal body of the cable in a vacuum insulation box, pass through the alkane gas and heat it to 600-800°C, so that the alkane gas is cracked into carbon atoms and hydrogen, and the temperature is maintained for 20-60min, so that the carbon Atoms penetrate into the metal body of the cable;

[0024] S20. Gradually lower the temperature inside the vacuum insulation box to 200-400°C and keep it for 3-10 minutes, then linearly lower the temperature inside the vacuum insulation box to 20-40°C within 10-30 minutes, so that the Carbon atoms are precipitated from the interior of the cable metal body and a graphene film is formed on the surface of the cable metal body to obtain the graphene composite cable.

[0025] Specifically, the metal body of the cable is put into a vacuum insulation box, and alkan...

Embodiment 1

[0033] 1) Place the metal body of the cable in a vacuum insulation box, pass in alkane gas and heat it to 600°C to crack the alkane gas into carbon atoms and hydrogen, and keep the temperature for 25 minutes so that the carbon atoms can penetrate into the Inside the metal body of the cable;

[0034] 2) Gradually lower the temperature inside the vacuum insulation box to 250°C and keep it for 5 minutes, then linearly lower the temperature inside the vacuum insulation box to 20°C within 10 minutes, so that the carbon atoms are removed from the cable metal The graphene film is precipitated inside the body and formed on the surface of the metal body of the cable to obtain the graphene composite cable.

Embodiment 2

[0036] 1) Place the metal body of the cable in a vacuum insulation box, pass in alkane gas and heat it to 700°C to crack the alkane gas into carbon atoms and hydrogen, and keep the temperature for 40 minutes so that the carbon atoms can penetrate into the Inside the metal body of the cable;

[0037]2) Gradually lower the temperature inside the vacuum insulation box to 300°C and keep it for 8 minutes, then linearly lower the temperature inside the vacuum insulation box to 30°C within 20 minutes, so that the carbon atoms are removed from the cable metal The graphene film is precipitated inside the body and formed on the surface of the metal body of the cable to obtain the graphene composite cable.

Abstract

The invention discloses a graphene composite cable and a preparation method thereof. The graphene composite cable comprises a cable metal body and a graphene film coating the cable metal body. In thegraphene composite cable, the graphene film serves as a protective layer of the cable metal body, and can isolate contact between other substances and the cable metal body, and protects the cable metal body; and since the graphene is composed of carbon, the carbon has very high stability, generally does not chemically react with other substances, and has good corrosion resistance; in addition, since the graphene has ultra-high conductivity, the effective load of the cable metal body is increased by 10% or more; and since the graphene film is transparent, the graphene composite cable can be checked very directly in the case of a cable failure.

Description

technical field [0001] The invention relates to the field of cables, in particular to a graphene composite cable and a preparation method thereof. Background technique [0002] In the prior art, there are various types of cables. In order to adapt to different types of work, continuous innovation is required, and more cables need to be born. Ordinary cables are exposed to wind and sun in the wild, and the exposed metal is easily corroded. Most of the cables now protect the inside of the cable by covering the metal outside with plastic, but because the plastic or rubber is too heavy, it not only increases the burden on the pole, but also because the aging speed of the plastic or rubber is generally faster, The final result is that the rubber of the cable is easily corroded, and finally the cable is oxidized. [0003] Therefore, the prior art still needs to be improved and developed. Contents of the invention [0004] In view of the above-mentioned deficiencies in the pri...
