Abstract

The invention relates to the technical field of production of tinned copper wires, and aims to provide a flux for producing continuous annealed tinned copper wires and a preparation method for the flux. The flux for the tinned copper wires is prepared from the following components: 0.3 to 0.6 percent of ethylene glycol, 0.3 to 0.6 percent of triethanolamine, 0.3 to 0.6 percent of glycerol, 0.05 to 0.12 percent of dimethylamine hydrochloride, 0 to 0.6 percent of zinc chloride, 0.3 to 0.6 percent of ammonium chloride, 1.6 to 2.6 percent of hydrochloric acid, and the balance of water. The flux is strong in welding aid property and good in welding aid effect, eliminates a cooper leakage phenomenon in continuous production, and is good in wetting effect, strong in welding capability, bright and smooth after being welded and easy to decompose at a high temperature; when the flux is matched with an exhaust fan, smog and peculiar smell are eliminated at a tin furnace; coatings of the produced tinned copper wires are bright and smooth; and the flux has good effects of protecting the coatings and preventing oxidation.

Description

technical field [0001] The invention relates to the technical field of tinned copper wire production, in particular to a tinned copper wire flux suitable for producing continuous annealed tinned copper wire and a preparation method thereof. Background technique [0002] In the production of wire and cable, the most commonly used plated wire is tinned copper wire, which is mainly used for conductive cores of rubber-insulated mining cables, rolling stock cables, and marine cables. After the copper wire is tinned, it can effectively prevent the oxidation of the copper wire and the rubber stickiness and blackening of the copper wire caused by the direct contact between the copper wire and the rubber, and at the same time improve the service life of the cable and the weldability of the core. [0003] At present, the production of tinned copper wire in my country's cable industry mainly includes chemical tinning (electrotinning) and physical tinning (hot tinning). The production p...
