For complexing agent；
(2) by weight, 6-10 parts of polyoxyethylene and 4 parts of polyhydroxy carboxylic acids sodium are stirred 60min, and stand curing
Material B is obtained for 24 hours, as surfactant；
(3) phytic acid is uniformly mixed to obtain material C with citric acid, as bleeding agent；
(4) by weight, 30 parts of material Cs, 5 parts of polyethylene glycol, 5-7 parts of sodium citrates (as corrosion inhibiter), 15 parts of materials are taken
B, 10 parts of materials As and 8-15 parts of deionized waters are uniformly mixed, and obtain material D after standing 48h；
(5) material D and copper sulphate are uniformly mixed by weight 100:2 and obtain plating solution.
Further, cooking conditions in the step (2) are as follows: temperature is 38 DEG C, humidity 80%.
Further, the mass ratio of phytic acid and citric acid is 3:1 in the step (3).
Further, the resulting bath pH value of the step (5) is 2-5.
Further, the method that the processing of rust removing uses for one of compressed-air blast cleaning, centrifugal blast cleaning and hand cleaning,
After processing of rust removing, substrate surface should adhere to without visible grease, dirt, oxide skin, iron rust, painting layer without attachment loosely etc.
Object.
Further, the copper plating treatment is that substrate is impregnated to 15-20s in the plating solution to obtain copper layer thickness not less than 3 μ
The plating Copper base material of m.
The beneficial effects of the present invention are:
(1) present invention uses phytic acid and citric acid for primary raw material, cooperates compound organic surface active agent, bleeding agent, corrosion inhibiter,
Complexing agent and copper sulphate as copper source；It is 2-5 in pH value using the synergistic effect of phytic acid, citric acid, activating agent and bleeding agent
Under the conditions of, iron ion in substrate surface oxide is rapidly converted into ferrous iron ferrous ion, in this, as reducing agent, by solution
In copper ion reduction deposition to substrate surface；Corrosion inhibiter can allow substrate not excessive erosion in acid condition simultaneously, this method
The quantity that reducing agent in solution is formed can be adjusted by adjusting the pH value of solution so as to adjust the deposition rate of layers of copper, and combined
Soaking time controls copper layer thickness.
(2) plating solution prepared of the present invention, can quickly sink copper, and adhesive force is strong, corner depressed area energy uniform deposition, and stingless
Swash smell, non-volatile, human body is accessible, and subsequent environment-friendly treating process is easy, and processing cost is low.
(3) present invention not only can solve quality of coating problem caused by substrate corrodes, moreover it is possible to solve to aoxidize because of substrate surface
Adhesive force caused by problem and anti-corrosion ability die down problem.
