In described metal conditioner, further include and be selected from nitric acid, sulfuric acid, phosphoric acid and their salt, it take solid components and concentration metering is 50-10000ppm.
The invention has the beneficial effects as follows:
Technical scheme of the present invention is by the usage ratio to titanium-containing compound and zirconium-containing compound, improved at the overlay film effect of pending metallic surface and the coating adhesion of rear operation, and pass through aminosilane and 1, the ratio of components of 2-bis-(triethoxysilyl) ethane and two (triethoxysilyl) hexane, has improved the corrosion resistance nature of overlay film.
Embodiment
Describe by the following examples technical scheme of the present invention in detail, should be understood that, following embodiment is only exemplary, only can be used for explaining and technical scheme of the present invention being described, and can not to be interpreted as is the restriction to technical solution of the present invention.
In the present invention, titaniferous compound and zirconium compound are for form the material of the chemical transformation overlay film that contains titanium and zirconium on metal material surface, although this two compounds belongs to common used material in metal finishing, but cannot reach best effect always, and, the composition of this two compounds or the difference of proportioning are all not identical in performance and the characteristic of the overlay film of metallic surface yet.In the present invention, what select is titanium fluoride, zirconium nitrate and three kinds of compounds of Zirconium tetrafluoride, titanium fluoride, zirconium nitrate and Zirconium tetrafluoride convert and account for 110-140ppm or the 550-650ppm for the treatment of agent total amount with metallic element, wherein, titanium fluoride is 1:1-1:3 with the ratio of the metallic element atom of zirconium nitrate and Zirconium tetrafluoride, and the ratio of the metallic element atom of zirconium nitrate and Zirconium tetrafluoride is 2:5.
In technical scheme of the present invention, when the ratio of titanium fluoride and the metallic element atom of zirconium nitrate and Zirconium tetrafluoride is 1:1, it is preferred version of the present invention that titanium fluoride, zirconium nitrate and Zirconium tetrafluoride be take the metallic element 550-650ppm that accounts for treatment agent total amount that converts; When the ratio of titanium fluoride and the metallic element atom of zirconium nitrate and Zirconium tetrafluoride is 1:3, it is preferred version of the present invention that titanium fluoride, zirconium nitrate and Zirconium tetrafluoride be take the metallic element 110-140ppm that accounts for treatment agent total amount that converts.
In the present invention, also include the free fluorine ion of 10-50ppm, and the PF value for the treatment of agent is 3.2-4.5.In treatment agent, adding free fluorine ion is in order to guarantee the stability for the treatment of agent, but the concentration of fluorion can not be too high, because when the excessive concentration of fluorion, although treatment agent stability improves, but separate out also, reduce, the plastic film mulching decreased on cast iron materials surface, weakens antiseptic property.
In treatment agent, also contain calcium cpd, magnesium compound and strontium compound, its Main Function is maintain fluorion stable.
In technical scheme of the present invention, aminosilane, 1,2-bis-(triethoxysilyl) ethane and two (triethoxysilyl) hexane generation condensation reaction, reactant in the overlay film of metallic surface for improving the erosion resistance of overlay film, and improve the tack that aftertreatment is filmed, its preparation method is for making aminosilane, 1, and 2-bis-(triethoxysilyl) ethane and two (triethoxysilyl) hexane are hydrolyzed and make in water, alcohol or acidic aqueous solution.
In technical scheme of the present invention, aminosilane includes 3-TSL 8330, APTES, 3-aminopropyl methyldiethoxysilane, N-phenyl-3-TSL 8330, N-(2-amino-ethyl)-3-TSL 8330 or N-(2-amino-ethyl) one or more combinations of-APTES.
Aminosilane and 1,2-bis-(triethoxysilyl) ethane and two (triethoxysilyl) hexane be take mol ratio as 17:3-9:1, wherein, 1,2-bis-(triethoxysilyl) ethane and two (triethoxysilyl) hexane be take mol ratio as 1:1.
At aminosilane of the present invention, 1, the final condenses solid components and concentration of 2-bis-(triethoxysilyl) ethane and two (triethoxysilyl) hexane accounts for the 220-280ppm for the treatment of agent total amount.
Method for anticorrosion treatment in the present invention is to be negative electrode electroplating processes by pending cast iron materials.Being about to cast iron materials connects and electroplates with electroplanting device negative electrode.
After plating, for improve treatment agent the wear resisting property of metallic surface and with the tack of filming, can add water-soluble or water dispersible organic resin, in the present invention, such as, epoxy resin, acrylic resin etc., wherein, the weathering resistance of epoxy resin is poor, does not select epoxy resin during to metal finishing for outdoor; The good weatherability of acrylic resin, and be applicable to low temperature, can be for extremely frigid zones, but the hardness of this resin is larger, and fragility is large, and time and overlay film thickness that when processing, the time is less than other resin also should reduce.When the resin using has acrylic resin, in solid composition, should not surpass 1000ppm, best with 50-300ppm.
In the present invention, nitrate radical mainly plays oxygenant effect, and can promote overlay film to separate out and improve the solvency action of calcium cpd, magnesium compound and strontium compound, to maintain the concentration stabilize of calcium cpd, magnesium compound and strontium compound.
In order to promote the formation of overlay film, improve the erosion resistance of overlay film, in treatment agent, can select nitric acid, sulfuric acid, phosphoric acid etc. and their salt, can also adjust on the one hand the pH value for the treatment of agent, the pH value of the treatment agent of this programme is optimum 3.2-4.5.
In order to improve the stability for the treatment of agent and the property separated out, can add tensio-active agent, mainly add anionic species tensio-active agent and/or nonionic class tensio-active agent.
