[0043] In the preparation method of graphene-coated metal powder of the present invention, metal powder and anti-sintering agent are mixed and graphene is grown in-situ by chemical vapor deposition, which can effectively avoid the sintering and agglomeration of metal powder in the high-temperature deposition process, and the post-treatment The process of removing the anti-sintering agent is simple and has no effect on the quality of the graphene-coated metal composite powder. Graphene is coated on the metal powder by chemical in-situ growth method, and the graphene has few structural defects and high quality. The anti-sintering agent can be washed away by water, and the purification treatment is simple, low in cost, economical and environmentally friendly.
[0044] The present invention prepares metal base-graphene wire and cable conductor according to the following steps, specifically as follows:

Embodiment 1
[0055] A metal-based-graphene wire and cable conductor is composed of graphene-coated copper powder, and the content of the graphene-coated copper powder is 100 wt%.
[0056] The method for preparing graphene-coated copper powder in this embodiment is specifically carried out according to the following steps:
[0057] Firstly, copper powder with a particle size of 200 mesh and magnesium oxide with a particle size of 1 μm were uniformly mixed at a mass ratio of 5:2 to obtain 280 g of mixed powder, which was placed in a chemical vapor deposition quartz tube chamber.
[0058] Then, the chemical vapor deposition quartz tube chamber was evacuated to 10 -3 kPa, argon gas is introduced at a flow rate of 513 sccm, so that the pressure in the chemical vapor deposition quartz tube reaches normal pressure, and the flow rate of argon gas is adjusted to 300 sccm, and hydrogen gas is introduced at a flow rate of 20 sccm. Raise the temperature to 1000°C at a speed of min, and then introduce...

[0065] A metal base-graphene wire and cable conductor is composed of graphene-coated copper powder, and the content of the graphene-coated copper powder is 100 wt%.
[0066] The method for preparing graphene-coated copper powder in this embodiment is specifically carried out according to the following steps:
[0067] First, 280 g of mixed powder was obtained by uniformly mixing copper powder with a particle size of 100 mesh and alumina with a particle size of 10 μm in a mass ratio of 5:4, which was placed in a chemical vapor deposition quartz tube chamber.
[0068] Then, the chemical vapor deposition quartz tube chamber was evacuated to 10 -3 kPa, argon gas is introduced at a flow rate of 150 sccm, so that the pressure in the chemical vapor deposition quartz tube reaches normal pressure, and the flow rate of argon gas is adjusted to 300 sccm, and hydrogen gas is introduced at a flow rate of 10 sccm. Raise the temperature to 1050°C at a speed of min, and then introduce methane...
