Using the organophosphor acid compounds of one or more, one or more kinds of Schiff bases compounds and one
Kind or more than one N, S heterocyclic compound compounded, in three kinds of compositions the control of every kind of Ingredient Amount 0.001~
500mmol/L, preferably 0.01~100mmol/L.
The present invention can use one or more kinds of nonionic surfactants, preferably APES type,
High-carbon fatty alcohol polyoxyethylene ether type and fatty acid methyl ester ethoxylate type.The above-mentioned total dosage control of surfactant is 0.01
~100mmol/L, more preferably 0.1~50mmol/L.
Described halogen or halide salts, metallic surface passivating film is dissolved by active anion, so as to form new guarantor
Cuticula, its salt are mainly alkali metal salt, particular certain cancers, sylvite.
The Ni-Pd metal conditioners of the material composition, it is characterised in that the pH controls of surface conditioning agent 1~
10, preferably 1~7.
A kind of Ni-Pd metals, nickel dam is obtained using electroless form, and palladium is replaced by chemistry on nickel coating surface
Method obtain a Ceng Ba islands, part of nickel exposed metal/bare metal is left in air in the Ni-Pd metal surfaces obtained by the technique.
When the surface conditioning agent using the present invention is surface-treated to metal, epithelium is formed using dipping or spraying
Method, preferably infusion process.Shape for metal to be treated can be any shape such as wire, plate, band, granular, by using
The surface conditioning agent of the present invention, after being surface-treated to Ni-Pd metal surfaces, it can be made to obtain excellent in oxidation resistance, weldering
The characteristics of expecting wetability.
Corrosion inhibiter main component organophosphor acid compounds of the present invention, Schiff bases compound and N, S are miscellaneous
The metallic atom of cycle compound energy metal material surface is attracted to metal material table by different degrees of coordination
Face, at the same the types of functionality group that carries of such compound by mutual synergistic function can metal material surface formed with
Machine epithelium and play corrosion inhibition.For the present invention by testing after 155 DEG C are incubated 20 hours, its welding performance keeps good.
Specific embodiment
Embodiment 1~6;Comparative example 1~8
13 kinds of surface conditioning agents are configured, after being incubated 20 hours at 155 DEG C after its active ingredient and film forming, bonding test result
Such as table 1.
Ni-Pd metal surfaces are obtained on substrate to obtain by the following method.
Alkali cleaning oil removing (10%NaOH, 2 minutes) → washing (normal temperature, 1 minute) → pickling (10%H2SO4, 1 minute) → water
Washing (normal temperature, 1 minute) → microetch (potassium peroxydisulfate 0.37mol/L, sulfuric acid 20ml, 3 minutes), → washing (normal temperature, 1 minute) → is living
Change (YC-42,3 minutes) → washing (normal temperature, 1 minute) → chemical nickel plating (YC-51M 100mL/L, YC-51A 48mL/L, YC-
51D 4mL/L, 84 DEG C, 8 minutes) → washing (normal temperature, 1 minute) → chemical palladium immersing (PdCl29mmol/L, ammoniacal liquor 80ml/L, lemon
Lemon acid 26mmol/L, OP-100.01ml/L, 40 DEG C, 30 minutes) → washing (normal temperature, 1 minute) → drying
The configuration of surface conditioning agent:
Corresponding surfactant is weighed by formula to be dissolved in distilled water, stirring is abundant to dissolving, and is dissolving sufficient table
Added in existing activator solution and be formulated the desired amount of all kinds of corrosion inhibiter materials, stirring is abundant to dissolving, and adjusts pH, static 30min
Constant volume afterwards.
Obtained metal is impregnated 0.5~15 minute in the surface conditioning agent configured at 0~100 DEG C, preferably 25~
Impregnated 1.5~10 minutes at 50 DEG C.
To 10, the film forming sample of each embodiment, after being handled 20 hours at 155 DEG C, bonding test is carried out, bonding is surveyed
The resistance to elevated temperatures and the welding performance after high-temperature process of the direct reacting metal of test result.
Bonding equipment:Hughes 2460II
Test equipment:Dages Series 4000
Beat gold thread:K&S Mod.4129,
Bonding pressure:5cN
Bonding time:5sec
Pulling force about 30cN
The different surface treatment agent of table 1,20 hours bonding test results are incubated at 155 DEG C after its active ingredient and film forming
By table above it can be seen that not reaching required effect as corrosion inhibiter active ingredient using schiff bases, work as schiff bases
With significant effect can be obtained when ATMP, 2- aminobenzimidazole collective effects, when Schiff alkali concn increases
Pull-off force increases, while the proportioning of each component can reach excellent effect in preferred scope, otherwise DeGrain;Adopt
The effect using nonionic Surfactant can not be reached with the effect of anionic surfactant sodium dodecylbenzene sulfonate;Make
It is more notable than using stearic acid welding effect with N, S heterocyclic compound;Metal after processed by the invention compared to comparative example 6
Effect is more excellent.
