Abstract
The invention discloses derusting and pickling pretreatment fluid for copper electroless plating of a steel substrate. The derusting and pickling pretreatment fluid is prepared from sulfuric acid, hydrochloric acid, phosphoric acid, a complexing agent, lauryl sodium sulfate, oxalic acid, stannous chloride, a corrosion inhibitor and water. The corrosion inhibitor and a reducing agent stannous chloride are added into the derusting and pickling pretreatment fluid so as to achieve the purpose of effectively preventing acid from corroding the surface of the steel substrate. The penetration, solubilization and cleaning functions of the lauryl sodium sulfate and alkylphenol ethoxylates are utilized so as to conveniently, quickly and effectively remove rusting and oxides, and an effect of effectively inhibiting acid mist. Moreover, due to the coordinating role with the complexing agent and acid fluid, the process is greatly simplified, and the efficiency is increased.

Technical field
The present invention relates to steel substrate electroless copper front surface processing technology field, espespecially a kind of rust cleaning pickling pretreatment liquid of steel substrate electroless copper.
Background technology
Electroless copper is to make metal copper ion under the self-catalysis of matrix surface, reduce the metallic copper deposition process of carrying out by reductive agent suitable in solution, also claim electroless plating copper or autocatalysis copper facing, electroless copper process nature is the process of redox reaction, belong to have transfer transport, without the electroless plating process of external power, toxic ingredient has been abandoned in nuisanceless chemical copper facing completely, adopt the nontoxic reductive agent of environmental protection, fundamentally control source of pollution, realize the cleaner production of electroless copper.Before the electroless copper of steel substrate, need matrix to carry out pre-treatment, pickling pre-treatment comprising corrosion and oxide compound, object is to remove corrosion and the oxide compound of steel substrate Surface Creation, the quality of steel substrate surface corrosion and oxide compound pickling pre-treatment directly affects the quality of electroless copper, so the pickling pre-treatment of steel substrate surface corrosion and oxide compound is one of pre-treating technology important before electroless copper, this just need to use the high-quality copper-plated rust cleaning pickling of the subsequent chemistry pretreatment liquid that is suitable for.
Summary of the invention
The present invention is for the oil removing scavenging solution of steel substrate electroless copper, and its object is the rust cleaning pickling pretreatment liquid that a kind of quick removal steel substrate surface iron rust is provided, meets steel substrate inhibition requirement and electroless copper requirement.
To achieve these goals, technology solution of the present invention is put case and is: the rust cleaning pickling pretreatment liquid of described a kind of steel substrate electroless copper is comprised of sulfuric acid, hydrochloric acid, phosphoric acid, complexing agent, sodium lauryl sulphate, oxalic acid, tin protochloride, inhibiter and water, and each component and quality percentage composition thereof are:
Sulfuric acid 0～10%
Hydrochloric acid 0～10%
Phosphatase 11 5～20%
Complexing agent 2～3%
Sodium lauryl sulphate 0～0.3%
Alkylphenol polyoxyethylene 0～0.2%
Oxalic acid 1～2%
Tin protochloride 0～0.4%
Inhibiter 0.5～1.5%
Water surplus
Under the condition stirring, to the sulfuric acid that slowly adds the dosage of filling a prescription in water, after sulfuric acid dilutes completely, again slowly to the hydrochloric acid, tin protochloride and the phosphoric acid that add the dosage of filling a prescription in solution, the complexing agent and the oxalic acid that finally add the dosage of filling a prescription, after fully stirring, obtain standby clear liquor; Under the condition stirring, to the inhibiter, sodium lauryl sulphate and the alkylphenol polyoxyethylene that add the dosage of filling a prescription in remaining water, continue to stir and be heated to 60～70 ℃, after each component is fully dissolved, add standby clear liquor, keep the temperature of 60～70 ℃, continue to stir, after solution is slowly cooling, stop stirring, pickling pretreatment liquid product must eliminate rust.
Further, described complexing agent is selected from one or more in citric acid, tartrate, phytic acid and ethylenediamine tetraacetic acid (EDTA) and salt thereof;
Described inhibiter is selected from one or both in thiocarbamide and urotropine.
Advantage and disadvantage of the present invention is: utilize inhibiter and reductive agent tin protochloride to join in rust cleaning pickling pretreatment liquid, reach the effective corrosion of acid to steel substrate surface that stop; Utilize infiltration, solubilising and the cleaning function of sodium lauryl sulphate and alkylphenol polyoxyethylene, be convenient to remove quickly and effectively corrosion and oxide compound, and reach the effect of effective inhibition acid mist; Meanwhile, with coordinative roles such as complexing agent and acid solutions, greatly simplify technique, improved efficiency.
