Problems solved by technology

[0003] The current copper plating process on the steel wire in the outer tire often adopts the plating solution of pyrophosphate and organic phosphine system. However, there are the following problems: (1) The hardness of the copper layer plated is low, and it is not suitable for tires to withstand heavy trucks, mines, etc. The gravity of mining machines and airplanes is not strong; (2) the bonding force between the coating and the steel wire is poor due to the easy displacement of copper on steel parts; (3) the current efficiency of the alkaline copper plating process containing phosphorus (phosphine) is low , the plating solution has poor resistance to impurities; (4) the copper plating solution contains a large amount of inorganic phosphorus and organic phosphine, which makes it difficult to treat the discharged wastewater and pollutes the environmental water quality

Abstract

The invention discloses an electroplating solution for alkaline electroplating copper-titanium alloy, a preparation method and an electroplating process. The formula of the electroplating solution is as follows: copper sulfate pentahydrate 25-40g/L, citric acid 90-110g/L, succinyl Amine 10-15g/L, titanium sulfate 10-25g/L, potassium hydroxide 100-120g/L, boric acid 25-35g/L, anti-copper replacement agent 0.01-0.05mg/L, gloss agent 8-12mg/L. The electroplating solution of the present invention is cyanide-free and phosphorus-free, and the electroplating process can obtain copper-titanium copper that is bright, fine, harder than a pure copper layer, strong in wear resistance, good in bonding with meridian rubber, and strong in sulfide corrosion resistance alloy plating.

Description

technical field [0001] The invention relates to the technical field of metal surface treatment, in particular to an electroplating solution for alkaline electroplating copper-titanium alloy, a preparation method and an electroplating process. Background technique [0002] As we all know, the use of wheeled mobile means of transport, heavy-duty work equipment (such as automobiles, tractors, aircraft, mining and construction machinery) all need to be set on the wheel hub to inflate the rubber inner tube and the outer tire composed of radial wire, steel wire belt, rubber, etc. , in order to move the transport. Among them, the role of the steel wire belt is particularly important, which requires strong rigidity, flexibility, bonding force with meridians and rubber, and corrosion resistance to sulfide. However, the steel wire belt itself has poor corrosion resistance to sulfide-containing rubber, which affects the bonding force between it and the rubber. ) destroyed people. In...
