Problems solved by technology

[0002] There are many types of enameled wires, such as pure copper wires, alloy wires, and copper-clad aluminum wires, but they have many disadvantages: high resistivity, heavy weight, high brittleness, and easy to break
At present, there is a graphene-coated wire with a copper core on the market, which can overcome the above shortcomings, but because the graphene is on the outer layer, this type of wire is generally thicker in diameter and cannot be used in many fields, and because the graphene is on the outer layer, welding is difficult higher

Embodiment 1

[0017] Embodiment one: see attached figure 1 Shown, a kind of production method of copper clad graphene wire, comprises the following steps:

[0018] 1) Inject graphene paste into the hollow copper tube;

[0019] 2) The copper pipe is stretched step by step into a wire with a diameter of 0.001mm by diamond die stretching method, and the stretching rate is 1.2 each time;

[0020] 3) Apply insulating varnish on the wire and dry it, repeat several times to form a paint film on the surface of the wire, and then apply self-adhesive varnish to form a self-adhesive layer;

[0021] 4) Cooling and take-up.

[0022] The copper-clad graphene wire produced in this embodiment is respectively a graphene core 1, a copper cladding 2, an insulating coating 3, and a self-adhesive layer 4 from the inside to the outside.

[0023] The graphene paste in this embodiment is a paste after mixing graphene (powder state) and additives such as solvent, resin, and surfactant.

Abstract

The invention discloses a method for producing copper-coated graphene lead wires. The method that copper tubes are injected with pasty graphene and stretched is adopted to produce the copper-coated graphene lead wires, and the technical problem that the copper-coated graphene lead wires are difficult to produce is solved.

Description

technical field [0001] The invention relates to a production method of a copper-clad graphene wire. Background technique [0002] There are many types of enameled wires, such as pure copper wires, alloy wires, and copper-clad aluminum wires, but they have many disadvantages: high resistivity, heavy weight, high brittleness, and easy to break. At present, there is a graphene-coated wire with a copper core on the market, which can overcome the above shortcomings, but because the graphene is on the outer layer, this type of wire is generally thicker in diameter and cannot be used in many fields, and because the graphene is on the outer layer, welding is difficult higher. Contents of the invention [0003] The purpose of the present invention is to provide a kind of production method that can wrap graphene in the copper-clad graphene wire in the copper cladding. [0004] In order to achieve the above object, the technical scheme adopted in the present invention is: a kind of...
