Description
Technical field
The present invention relates to wire rod manufacture field, more particularly to a kind of copper-plating technique of aluminum wire rod.
Background technology
Copper-plated technique had developed in recent years on aluminium and aluminum alloy base material, was computer casing, automotive hub, outside mobile phone
The usual way of the product surfaces such as shell processing.The main purpose of the copper coating technique of this several prods is in product surface shape
It is good into thermal diffusivity, ornamental strong metal decorative pattern.Copper material is due to its superior electric conductivity, as good conductive material always
Electronics industry is widely used in, but copper material is on the high side, virtually adds production cost using copper material completely, herein
In the case of, Many researchers research carries out copper coating come reinforcing material electric conductivity with less expensive aluminium.But this warp
The coating binding ability of copper coating processing is not fine, and compactness is poor, and anti-wear performance and impact resistance are poor, and coating is easier to
Peel off.
The content of the invention
The purpose of the present invention is a kind of copper-plating technique of aluminum wire rod the defects of overcoming prior art and provided.
The technical solution adopted by the present invention is：The copper-plating technique of aluminum wire rod, its step include：Horizontal casting → cold rolling →
Hypoxemia annealing → drawing plane → hypoxemia annealing → Diluted Acid Washing → more closing mould stretchings → moves back zinc → bell-type annealing → copper facing → test package；Its
In, l160 DEG C of casting temperature~1250 DEG C, 0.8~1.6 m/min of casting speed, pickling use concentration for 5~20% it is dilute
Sulfuric acid solution, 40~85 DEG C of pickling temperature, annealing add nitrogen and make protection gas, 390~410 DEG C of annealing temperature, soaking time 90
~120 minutes, the aluminum steel after leaching zinc is put into every liter of solution containing 200~500ml nitric acid and moves back zinc, aluminium wire is put into
Among the mixed solvent of every liter of copper sulphate containing 50~85mg and appropriate brightener, 30~35 DEG C of temperature, current density be 2~
Copper facing under conditions of 5A/dm2.
The beneficial effects of the invention are as follows：The present invention makes process simple, reduced a large amount of due to eliminating nickel plating step
Production cost, according to the product of its processing, it is coated, and layers of copper associativity is good, and compactness is good, wear and shock-resistant, has good lead
Electrical property, its copper plate also have good ductility, and the product can be processed to conductive electrode etc. without because product is curved
Folding destroys its copper plate.
