本発明は、ベンゾトリアゾールを用いて銅線表面に耐食
性にすぐれた防錆皮膜を形成させる製造方法に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a manufacturing method for forming a rust preventive film with excellent corrosion resistance on the surface of a copper wire using benzotriazole.

や銅撚線の表面が変色することがある。Conventionally,! During storage of l1iI wires, V4 wires, and stranded copper wires, or during the manufacturing process and storage of insulated wires, the surface of copper wires and stranded copper wires may become discolored.

させることが提案されている。Therefore, in various manufacturing processes, copper wires, stranded copper wires, etc. are coated with benzotriazole or/and its derivatives and other anticorrosion solutions for copper to perform antirust treatment. In addition, a black oxide film forms on the surface of the hard copper stranded wire used for outdoor distribution lines several years after it is installed, and in rare cases, the hard copper stranded wire breaks in an abnormal knife-cut pattern. May cause stress corrosion cracking. Therefore, as a countermeasure, benzotriazole or/and its derivatives are used to prevent the surface of the hard copper stranded wire from being oxidized even if corrosive rainwater (corrosive substances contained in rainwater) enters the wire from the terminal end. It has been proposed to form a rust-preventing film by using

防錆皮膜を形成させている。Generally, in order to form a rust-preventing film on the surface of a copper wire, droplets of a 0.5-3% anti-rust solution containing benzotriazole or its derivatives dissolved in a volatile organic solvent or water are applied to the running copper wire. Flowing, spraying or! The l1iJ wire is immersed in a rust preventive solution, the excess solution adhering to it is squeezed out, and the wire is dried to form a rust preventive film.

ができない。However, when a rust preventive solution containing benzotriazole or the like dissolved in a volatile organic solvent such as methyl alcohol is applied to a copper wire and the solvent evaporates, the added benzotriazole or the like precipitates as a solid, forming a chelate compound with copper. , that is, no rust preventive film is formed. In addition, since the rust preventive film formed is colorless and transparent, it is not possible to visually determine whether the rust preventive film has been formed reliably from its appearance. Furthermore, if dirt such as oil or fat is attached to the surface of the copper wire, there is a problem that a reliable rust-preventing film cannot be formed even if the above-mentioned rust-preventing solution is applied. Therefore, if the method of applying the anti-rust solution is not appropriate, even if the copper wire is subjected to anti-rust treatment, it may discolor in a short period of time if left in a high temperature and humidity atmosphere, or the hard copper stranded wire used for outdoor distribution lines may become discolored. Even if anti-corrosion treatment is applied, it is not possible to form a rust-preventive film on hard copper strands that can withstand a long-term corrosive environment.

法を提供することを目的とするものである。The present invention was made in view of the above-mentioned problems, and it is possible to reliably form a strong rust-preventing film with benzotriazole on the surface of copper wire, and to prevent the copper wire from being exposed to nature or immersed in a corrosive aqueous solution. The object of the present invention is to provide a method for manufacturing a corrosion-resistant copper wire that maintains its copper color over a long period of time.

ある。The manufacturing method of the present invention includes running a copper wire in a three-component rust-preventing solution of benzotriazole-water-chlorine solvent heated to at least 50°C or higher in a container. The copper wire is passed through or repeatedly held in a vapor atmosphere to continuously form a rust-preventing film with benzotriazole on the surface of the running copper wire.

ンを単独で用いるよりも効率的に行なうことができる。What is a benzotriazole-water-chlorinated solvent antirust solution?
The benzotriazole is dissolved in the minimum amount of methyl alcohol and stirred into a mixed solution of water and 1,1°1 trichloroethane (the mixing ratio of water is preferably in the range of 10% to 80%). The triazole concentration was set to 0.
It is preferably in the range of 5 to 3.0% by weight and heated to 50 to 70°C. When using such a mixed solution of water and 1.1.1 trichloroethane, the cleaning of the copper wire surface and the formation of a rust-preventive film on the surface are more effective than using 1.1.1) trichloroethane alone. It can be done efficiently.

過させて、走行する銅線上に防錆皮膜を形成させる。A running copper wire is immersed in the rust preventive solution, and then the copper wire is passed through the heated vapor atmosphere of the rust preventive solution, or this process is repeated to form a rust preventive film with benzotriazole on the surface of the copper wire. For example, a container for forming a copper wire is formed by installing pulleys in multiple stages at the upper and lower parts of the container, providing an inlet and an outlet for the copper wire, inserting the copper wire from the inlet, and inserting the copper wire into the upper and lower pulleys. It is preferable to make the wire go around in multiple stages so that it can be pulled out from the outlet. Then, pour a benzotriazole-water-1,1,1)lichloroethane-based rust preventive solution into the container so that about 173rd position of the lower pulley is immersed, and heat it to 50-70°C. A vapor atmosphere is formed in the space by the rust preventive solution. The upper end of the container is cooled to prevent vapor components from volatilizing, and the container is repeatedly immersed and passed through a vapor atmosphere to form a rust-preventing film on the running copper wire.

なり、銅線の周回作業がわずられしくなる。Next, the ratio of the length of the running copper wire immersed in the anti-rust solution to the length of the copper wire passing through the heated vapor atmosphere of the anti-rust solution is set to 1. In this case, it is preferable to set the latter to a range of 1 or more. It is preferable to lengthen the length of the tube through which it passes through the steam atmosphere inside the container, but it should not be made longer than necessary. The longer it is, the larger the container becomes, making it more difficult to work around the copper wire.

Pour benzotriazole-1,1,11-lichloroethane-based rust preventive solution into the solution up to the third position, or so that the length of the copper wire immersed in the solution is equal to the length of the copper wire passed through the steam atmosphere. Then, the rust preventive solution is heated to 50 to 70°C, the running copper wire is immersed in the rust preventive solution, and then the copper wire is passed through the vapor atmosphere of the heated rust preventive solution, or this process is repeated. However, when the copper wire is pulled out from the outlet, a rust-preventing film with excellent corrosion resistance can be formed on the surface of the running copper wire.
