Abstract

An antioxidant for cooling a copper wire comprises the following components in percentages by mass: 6-7% of benzotriazole, 35-40% of glycol, 5-6% of a wetting agent, 4-5% of a surfactant, and deionized water to 100%, and preferably comprises the following components in percentages by mass: 3-4% of beta-mercaptobenzothiazole, 2-5% of sodium hexametaphosphate and 3-5% of phosphite. By the antioxidant, a compact antioxidative protecting film can be formed on the copper wire, and the oxidation resistance of the copper wire is improved effectively, so that the copper wire has long quality guarantee period and low oxygen content. The antioxidant is simple and reasonable in proportioning, low in cost and suitable for industrial application.

Description

technical field [0001] The invention relates to the production field of copper wires, in particular to a special antioxidant for making copper wires. Background technique [0002] In the process of manufacturing copper wire, affected by high temperature, copper wire is easy to react with oxygen, which generally shortens the service life. Especially when it is used as a wire, a layer of oxide film will be formed at the joint and will not conduct electricity. In severe cases, the resistance of the wire will increase and it will easily cause a fire. [0003] Benzotriazole is mostly used as a vapor phase corrosion inhibitor in the production of copper and copper alloys. It has excellent performance, almost no odor, and is non-toxic. However, in the copper wire production process, the anti-oxidation film formed on the surface of the copper wire is easily destroyed during the stranding or extrusion process, resulting in a decrease in the anti-oxidation effect.
