Description
Technical field
Present invention relates particularly to a kind of Electroplate liquid of alkaline zinc-nickel alloy, also relate to a kind of Electroplate liquid of alkaline zinc-nickel alloy
Preparation method and application, belong to electroplating technology field.
Background technology
Zn-ni alloy deposits is a kind of novel excellent protective coating, be mainly used in Aero-Space, auto industry and
In mechano-electronic product.In electric field component surface anticorrosion and protection, admiro film layer is as final protecting film
Layer, it is desirable to it possesses excellent corrosion resistance, wearability and hardness etc..
At present, Zinc-nickel alloy electroplating technology has been put into actual application abroad, and the admiro on domestic production line
Electroplate liquid relies primarily on external import.Owing to the industrial circle of admiro film layer was expanded in the last few years so that it is become
The indispensable important process technology such as anticorrosion, decoration, therefore, a kind of Electroplate liquid of alkaline zinc-nickel alloy of research and preparation method thereof
It is particularly important, has important meaning especially for the anti-corrosion capability increasing high-voltage switch product shaft element etc.
Justice.
Chinese patent (notification number: CN 101240437 B) discloses a kind of plating solution formula, contains in every liter of electroplate liquid
Following components: zinc oxide 10～30g, nickel sulfate 5～13g, sodium hydroxide 100～140g, chelating agent be ammonium citrate 5～40g,
Triethanolamine 38～80ml, ethylenediamine 25～40ml, diethylenetriamine 3～20ml, more than TEPA 3ml, Soluble tartar.
Two or more in sodium 15～25g, EDTA8～15g, ammonia 10～20ml, what additive was epoxychloropropane with amine is anti-
Answer in product 1.5～15ml and phytic acid 0.05～15ml, sodium phytate 0.1～5g, CTAB0.1～5g any one, light
Agent is ZB1～10ml, one or more in vanillin 0.2～2g, thiourea 1～2g, saccharin 1～5g, and surplus is water.But,
The additive and the brightener that use in said method are the most single, it is difficult to meet the requirement of coating combination property, such as its plating
Efficiency is low, and 20min only has 6 μm, and film layer is relatively thin, is extremely difficult to higher corrosion resistance, does not additionally have the performance parameter of coating hardness,
The wearability requirement of High-Voltage Electrical Appliances axial workpiece cannot be applicable to.
Summary of the invention
