Abstract
A process for forming colour enamelled anodized film on surface of aluminium or aluminium alloy products includes such steps as surface treatment (deoiling and chemical polishing), enamelled anodizing in enamelled anodizing liquor at 30-55 deg.C and 20-55 V for 20-90 min, oxidizing to form enamelled anodized film, washing in clean water, and colouring treatment at 15-50 deg.C for 1-10 min in mixture liquid for dyeing and fixating. Said anodized film features uniform lustre and firmly adhered colour enamelled anodized one.
Description
The invention belongs to aluminium and alloy product surface decoration and functional processing scope.
At present, aluminium and alloy product adopt technologies such as electrochemical anodic oxidation, chemical oxidation to carry out corrosion-resistant, the ornamental processing in surface usually, have as oxidizing solution: sulfuric acid, chromic acid, oxalic acid, phosphoric acid etc., the anode oxide film that obtains has superior corrosion resistance, insulativity, wear resistance etc., and can utilize the characterization of adsorption of rete to use inorganic, organic dye to dye and handle the good decoration effect that reaches the aluminium product.That uses aborning at present has only the rete that obtains from the sulphuric acid soln processing of dyeing, but is prone to decolouring, and the rete decorative effect is not plentiful.The rete that obtains from chromic acid, boric acid mix acid liquor is the ceramic oxidizing film, and rete is opaque canescence, and outward appearance is similar to enamel layer.This kind rete is subjected to people's favor deeply as the surface abrasion resistance ornament layer of aluminum knitting needle, and obtains consumers in general's welcome.But the knitting needle color and luster of this kind rete is single, does not also have the report about colored porcelain metallization processes at present.Traditional sulfur acid anodizing rete dyeing is also because its results of use of cause influence such as film dyeing is not firm, decolourings.Moreover China China Machine Press publish " the electroplating technology handbook is narrower to chromic acid solution composition, temperature, the voltage range of electrochemical enamelizing process stipulation, and improper use will influence the quality of film.
The purpose of this invention is to provide a kind of aluminium and aluminum alloy colour porcelain texture oxidation preparation method, adopt this method to make rete have good multicolour, and make dye firm, even, good decorating effect, corrosion-resistant, wear-resistant, enlarge aluminum knitting needle and the anodized processing range of alloy product colour porcelain.
Aluminium of the present invention and aluminum alloy colour porcelain texture oxidation preparation method have the following steps:
At first, aluminium and alloy product are carried out degreasing, surface such as chemical rightenning clear Xian handle, then aluminium that clear Xian is handled well and alloy product be seated in temperature be 30～55 the degree, voltage is the enamelled anodizing that carried out in 20～55 volts the enamelled anodizing liquid 20～90 minutes, make aluminium and alloy product surface form the enamelled anodizing rete by oxidation, to form the aluminium of ceramic oxidizing rete and alloy product then carries out clear water and floats Xian and handle by taking out in the enamelled anodizing liquid, the aluminium and the alloy product that will have the enamelled anodizing rete again after clear water floats Xian are seated in dyestuff and the fixation that temperature is 15～50 degree, the dyeing of carrying out 1～10 minute in the sealing mixed solution is handled, after the dyed processing, it is even just to form color and luster on aluminium and alloy product surface, firmly, colour porcelain anode oxide film elegant in appearance.
Wherein, when aluminium and alloy product carried out the enamelled anodizing processing, the preparation of employed enamelled anodizing liquid was: elder generation is with the chromium trioxide (CrO of 30～55g/L (grams per liter)
3) be dissolved in water, boric acid with 1～6g/L is dissolved in the hot water of 100ml again, the water temperature of hot water is 70～80 degree, then chromium trioxide solution is mixed with boric acid solution, the water that adds prescribed volume again, then make enamelled anodizing liquid, when solution in use has a large amount of aluminum ions to occur, can add an amount of stablizer and adjust.
Wherein, when aluminium and alloy product dyeed and handle, the preparation of employed dyestuff and fixation, sealing mixed solution was: be earlier 40～50 spend the hot water dissolving of 200ml with the dyestuff of 0.5～10g/L and temperature, selecting various content then for use is 0.1～2g/L: Zn
2+(zinc), Ni
2+(nickel), Co
2+1(cobalt), Ba
2+(barium), F
-The fixing color and sealing agent of (fluorine) mixes with dissolving dyestuff well, adds acetic acid and water is added to prescribed volume, then makes dyestuff and fixation, sealing mixed solution.
Advantage of the present invention is: the oxidation liquid that enamelled anodizing liquor ratio of the present invention is general allows the temperature range of use wide, and voltage range is wide, and oxidation liquid long service life.Especially dyestuff of the present invention and fixation, sealing mixed solution, collection dyeing, fixation, the multiple function of sealing are one, shortcomings such as the painted complex process of conventional oxidation film, operation inconvenience have been overcome, the present invention is easy to use, after the dyed fixation treatment of rete, can keep bright in colour, even, firm, elegant in appearance, good, the corrosion resistant good rete of wear resistance, its rete promptly has the enamel sense and has plentiful effect attractive in appearance again.
