Abstract
A monochromatic dyeing method of organic dye for anodized aluminium alloy is carried out by loading and hanging pre-treating workpiece, carrying out first dyeing for 0.8-1.5min under the conditions of pH 4.5-5.5 and temperature 50-60 deg.C, not reaching required color, carrying out second dyeing for 18-22s and 0.8-1.2min under the conditions of pH 4.2-4.8 and temperature 50-60 deg.C, not reaching required color, regulating dye, pH, temperature and time according to the second dyeing process condition, carrying out multiple dyeing until required color is closed and dried.
Description
The present invention relates to a kind of unicolor chemical staining method, particularly a kind of organic dye solid shade dyeing method, it is applicable to that no substantive dyestuff such as aluminium and alloy anodized film thereof dye unicolor occasion.
In background technology, dying unicolor organic dye dyeing method is confined to single substantive dyestuff and dyes true qualities, as dying black with nigrosine, with alizarin look red colouration etc., and it is still unresolved always that employing chemical staining methods such as dark brown, bronze-colored, grass green, fairy green are dyeed, and can only be undertaken by adopting colorize method, be faint in color so exist, defectives such as cost height for overcoming these defectives, are dyed unicolor organic dye dyeing method to no substantive dyestuff and are developed.
The purpose of this invention is to provide a kind of organic dye solid shade dyeing method that can dye any monochrome, color clear, Anodising aluminium alloy that cost is low.
The object of the present invention is achieved like this:
It comprises that product dress extension carries out pre-treatment and washing, also comprises:
The chromophore of at first using different organic dye can absorb the absorption and the interference of light principle of different light waves and light, according to required color, determines to make behind body color and the complementary colors staining fluid of different colours in contiguous two or three organic dye on color ring,
To immerse in first kind of staining fluid through the clean back of the product water washing of anodic oxidation treatment then, pH value be 4.5-5.5, temperature be carry out under 50-60 ℃ the condition for the time 0.8-1.5min the dyeing first time and wash,
Before utilizing oxide film after a kind of staining fluid dyeing, not seal again, still have the multiple adsorb ability and add the painted characteristic of layer, to carrying out not reaching after the dyeing first time product of required color, it is immersed in second kind of staining fluid, at pH value is 4.2-4.8, temperature be under 50-60 ℃ the condition to secondary and repeatedly painted product carry out respectively for the time 18-22s, 0.8-1.2min second time dyeing and washing, do not reach the product of required color yet, make suitable technological test by painted processing condition for the second time and adjust dyestuff, pH value, repeatedly dye again after the temperature and time scope and wash, after reaching required monochrome, seal, oven dry.
Fig. 1 is applied to once painted process flow sheet for the present invention.
Fig. 2 is applied to secondary or repeatedly painted process flow sheet for the present invention.
Fig. 3 is the synoptic diagram of organic dye color ring of the present invention.
Below in conjunction with accompanying drawing, the present invention is done to describe further:
Product dress extension carries out pre-treatment and comprises electrochemical deoiling → heat, cold wash → 20 Rare nitric acid of-35% is washed → cold wash → chemical polishing → secondary cold wash → 40-60 The red fuming nitric acid (RFNA) of % is washed → secondary cold wash → sulphuric acid anodizing. Chemical polishing soln In can add a small amount of sulfosalicylic acid and hexamethylenetetramine is made corrosion inhibiter, through removing Product surface after oil, pickling, chemical polishing are processed should be even, bright, anode Oxidation technology requires to press: sulfuric acid 200 grams per liters, voltage 14-16 volt, current density 1. 5-2.5A/dm2, the time, 25-35min controlled, the product after anodic oxidation To wash 20-40S with the flowing cool water pendulum, preferably without ammonia neutralization, because residual ammonia The aqueous solution is bigger to the impact of the pH value of dyeing liquor, really will be with ammonia neutralization, in With after must clean up. Before dyeing, do not use in addition bare-handed contact product, To avoid affecting the uniformity of dye layer. In dyeing course, the pH value meeting of dye liquor Progressively raise, therefore will often test the pH value of dye liquor, if higher available 1: 1 vinegar Acid solution is regulated, and dye liquor is through repeatedly regulating the poststaining effect when bad or contaminated, Should in time change.
Sealing can adopt hot distilled water or steam to carry out, and the hot distilled water closure temperature is 90-100 ℃, the time is 5-10min, and the temperature of vapour seal is 95-110 ℃, Time is 15-30min. Oven dry can be carried out in temperature is 50-60 ℃ scope.
The compound method of dyeing liquor is for to place respectively container with load weighted dyestuff, , stirring with its furnishing pasty state or be stirred to whole profit temperature with deionization or distilled water Lower heating is boiled to 4-5min, and cooled and filtered is then the good dye liquor difference of filter Pour in the staining trough, the volume that adding distil water or deionized water to required system is joined, Regulate the dyeing liquor pH value with 1: 1 acetum under stirring, dye liquor is heated to technology Given temperature can come into operation after trial dyeing is qualified.
Enumerate pH value, temperature and time processing parameter that several application the present invention dye unicolor corresponding organic dye and its staining fluid of preparing below:
Embodiment one (dying dark brown):
2.0-2.5g/l 0.1-0.2g/lPH 4.5-5.0 50-60℃ 0.8-1.2min ( ) ： 0.5-1.0g/l 0.08-0.12g/lPH 5.0-5.5 50-60℃ 1-1.5min ( ) ：： 0.25-0.35g/l 0.05-0.06g/lPH 4.5-5.0 55-60℃ 1-1.2min： 0.25-0.3g/l 0.08-1.0g/l 0.05-0.08g/l PH 4.5-4.8 50-55℃ 18-22s ( ) ：： 0.6-1.0g/l 0.1-0.15g/lPH 5.0-5.5 50-60℃ 1-1.5min： 0.25-0.35g/l 0.1-0.15g/l 0.08-0.12g/l PH 4.2-4.8 50-60℃ 0.8-1.2min： 0.25-0.3g/l 0.15-0.2g/lPH 4.5-5.0 50-60℃ 10-20S
The present invention compares the good effect that produces with background technology: 1, can dye arbitrarily monochromatic. 2, color clear. 3, cost is low.
