Problems solved by technology

[0002] Aluminum alloy wire core conductor is a necessary material for cables and control cables. Existing aluminum alloy wire electroplated copper products often have the following disadvantages: the price and weight of copper are higher than that of aluminum, the cost is high, and the surface of the copper layer is easily oxidized to form an insulating film ;Due to the great difference in the electrode potential of the metal contact interface of copper-plated products, when the copper-plated surface is damaged, it is easy to corrode or even rot, which greatly affects the use effect of the product
[0003] At this stage, aluminum is gradually used to replace copper, but the biggest disadvantage of aluminum is that the surface is easily oxidized to form film resistance. Therefore, it is particularly important to carry out anti-corrosion treatment on the surface of aluminum alloy materials in cable structures.

Abstract

The invention relates to the field of aluminum alloy wire surface treatment, in particular to aluminum alloy wire surface reaction film treatment liquid and a treatment process thereof. According to the invention, the surface of the aluminum alloy wire is treated by adopting the treating fluid prepared from specific raw materials according to a specific ratio and a specific treatment process, so that micropores in the surface of a plating layer and the post-treated surface of metal can be effectively sealed and plugged, and harmful gas and corrosive media are prevented from invading; therefore, the phenomena of generation of trapping points on the surface of the coating and corrosion and yellowing of the coating are reduced.
