Problems solved by technology

[0003] However, the strength of the current copper-clad steel wire is relatively weak, and it is easy to break, causing the wire to be easily damaged and affecting normal transmission; for this, the current market generally adopts a multi-layer cladding structure to solve the problem of easy breakage, such as setting an insulating layer, an alloy layer, metal layer, fiber layer, anti-oxidation layer, composite material layer, etc., but excessive coating affects the flexibility of the wire, which is not conducive to processing and use

Abstract

The invention relates to the technical field of wire rods, in particular to a tinned copper-clad steel wire rod and a preparation process thereof. The tinned copper-clad steel wire rod includes a core layer, a copper layer and a tinned layer in sequence from the inside to the outside, and the tinned layer The thickness of the copper-clad steel tinned wire rod is 1-3 μm; the preparation steps of the copper-clad steel tinned wire include: A, steel wire drawing; B, electroplated copper layer; C, wire drawing and annealing treatment; D, cooling and air-drying treatment; E, tinning treatment. The tin-plated copper-clad steel wire rod of the present invention has a novel structure, simple preparation process and operation, and is easy to control. The protection of the wire improves the anti-oxidation effect of the wire, and the copper layer is not easy to be oxidized, discolored or corroded, which prolongs the service life of the wire and has high practicability.

Description

Technical field [0001] The present invention relates to the field of wire, and more particularly to a copper-clad steel tin-plated wire and a preparation process thereof. Background technique [0002] The surface layer of the copper wire wire is copper, with good conductive properties, and the inner layer is high-quality carbon steel, the principle of skin effect, is excellent in magnetic magnetic properties, and the electrical resistance is lower than steel, galvanized steel, and other conventional materials; Since it has good signal transmission performance and excellent mechanical properties to be widely used in data transmission. [0003] However, the current copper-clad wire strength is relatively weak, easy to break, resulting in easily damage to the wire, which affects normal transmission; in this, the current market is generally used in the market, such as setting an insulating layer, alloy Layers, metal layers, fibrous layers, antioxidant layers, composite layers, etc., ...
