Abstract
The present invention discloses a method for coloring aluminum anodic oxide films through chemical coupling reaction, which comprises the following steps: aluminum anodic oxide films suitable for coupling reaction are firstly prepared; coupling components are then embedded in film holes of the aluminum anodic oxide films; diazo components finally reacts with the coupling components in the film holes in a coupling mode. In the present invention, coupling components of pigment which has the characteristics of non-water solubility, favorable symmetry and light resistance are embedded in the film holes of the aluminum anodic oxide films so as to overcome the defect that the whole pigment molecule does not easily enter the film holes of the anodic oxide films; color film layers obtained through coupling reaction with diazo components have the advantages of corrosion resistance, light resistance and favorable decorative effect. The present invention has the advantages of simple technological operation and mild conditions, and is suitable for large-scale industrial production.
Description
Technical field
The present invention relates to a kind ofly carry out method of colouring, particularly relate to and a kind ofly carry out method of colouring in the micropore of aluminum anodized film by chemical coupling reaction pair aluminum anodized film takes place by chemical coupling reaction pair object.
Background technology
The aluminum anodized film method of colouring is mainly contained: electrolytic coloring and integral colouring.Wherein electrolytic coloring belongs to a kind of in the chemical coloring process, be with aluminum anodized film re-electrolysis in containing the solution of metal-salt, metal-salt is deposited in the micropore of aluminum anodized film, thereby make the aluminum anodized film colour generation, the painted membranous layer corrosion resistance that this method obtains is good, but look dark and dull coloring.Second kind of chemical coloring process is to be added with color substance to obtain coloured sunization film in anodizing of aluminium liquid, and also there is look dark shortcoming in this aluminum anodized film colorize method.The third chemical coloring process is aluminum anodized film to be immersed in the water-soluble dye solution dye, and obtains painted rete, the colored film lovely luster that this method obtains, but photostabilization is poor, fugitive color.
Summary of the invention
The object of the present invention is to provide and a kind ofly carry out method of colouring in the micropore of aluminum anodized film by chemical coupling reaction pair aluminum anodized film takes place, make the aluminium surface obtain anti-corrosion, photostabilization good, painted rete beautiful in colour.
In order to realize the technical scheme of goal of the invention employing: a kind of colorize method of aluminum anodized film, preparation earlier is applicable to the aluminum anodized film of coupled reaction, follows these steps to operation then:
(a) coupling component is embedded in the fenestra of described aluminum anodized film;
(b) make coupling component generation coupled reaction in diazo component and the described fenestra;
Coupling component described in the step (a) is selected from N, and N '-diphenylprop diamide or 2-Naphthol is mixed with 5～30% DMF solution, and the described alumilite process diaphragm after will cleaning then immersed in the solution 5～45 minutes;
Diazo component described in the step (b) is chosen the diazonium salt of aniline hydrochlorate, and the described alumilite process diaphragm that is embedded with coupling component in the fenestra is immersed in the diazonium salt solution of new system, and temperature is controlled to be below 5 ℃, and dipping time is 10～60 minutes.
The aluminum anodized film of coupled reaction prepares like this: the cleaning aluminium flake of pre-treatment is placed the anode place, and immerse in the electrolytic solution of 5～25% sulphuric acid soln, with operating voltage 10～30V, 5～35 ℃ of electrolysis temperatures, handled 10～90 minutes, and made the aluminium surface obtain being applicable to the anode oxide film of coupled reaction.
Be applicable to the preferred preparation like this of aluminum anodized film of coupled reaction: the cleaning aluminium flake of pre-treatment is placed the anode place, and immerse in the electrolytic solution of 5～25% sulphuric acid soln, with operating voltage 25V, 28 ℃ of electrolysis temperatures, 20～60 minutes treatment times obtained being applicable to the alumilite process diaphragm of coupled reaction.
The technical solution used in the present invention is compared with existing aluminum anodized film colorize method, have tangible advantage and positively effect: the present invention forms aluminum anodized film earlier, then with water-insoluble, symmetry is good and have the coupling component of certain sunproof pigment to be embedded in the fenestra of aluminum anodized film, again with itself and diazo component coupled reaction, the material component of coupling pigment enters respectively in the aluminum anode membrane micropore, overcome whole pigment molecule and be difficult for entering shortcoming in the alumilite process fenestra, anti-corrosion by the colored film that coupled reaction obtains, fast light, good decorating effect, technological operation of the present invention is simple, mild condition is fit to large-scale industrial production.
