Abstract
The gold titanate yellow aluminium alloy colouring method includes the following procedures: degreasing, caustic corrosion, neutralization, oxidation, electrolytic colouring, hole sealing and drying in airing. The formula of electrolytic colouring liquor includes 0.5-20 g/L of selenate, 8-16 g/L of sulfuric acid, 15-40 g/L of explosion-proof agent, 15-40 g/L of conducting medium and 30-45 g/L of hydrogen inhibitor, and its technological parameters are: temp. is 25-80 deg.C, voltage is 8-22 V and colouring time is 0.5-6 min.. Said invented colouring method can obtain the aluminium alloy section material possessing gold titarate yellows, pure and true colour, good stability and containing no other colour.
Description
The present invention relates to a kind of titanium-golden yellow alumium alloy colouring processing method.
Present domestic aluminum alloy section bar anode oxidation, electrolytic coloring main technique flow process:
Oil removing, alkaline etching, neutralization, anodic oxidation, painted, sealing of hole, air-dry, warehouse entry
Coloring process wherein has several different methods.The chemical stain rich color, tone is plentiful, but solidity to corrosion, fixation, weather resistance are relatively poor, and architectural aluminum section painted seldom adopts this method.The present painted main employing electrocolor process of architectural aluminum section.The fixation of electrolytic coloring, solidity to corrosion, weather resistance are good, and shortcoming is that tone is more single.Main coloring process has the bronze series based on the mixed salt of pink salt, nickel salt or nickel one tin.In addition, other color product also has produced in small quantities or testing laboratory's development technique as golden yellow, redness, grey etc.
Golden yellow coloring process roughly is divided into three major types: silver salt, manganese salt and be the coloring process of representative with oxysalts such as selenate, molybdates.Silver salt, the golden yellow technology of manganese salt is maturation comparatively, but the existing market occupancy volume is little.Oxysalt such as selenate, molybdate adopts the old process electrolytic colouring technology can't obtain darker golden yellow product, can't form golden series product from shallow to deep.Various golden yellow coloring process to such as the table (one)
| Component | ????g/l | Time min | Tone | Remarks | |
| ??AgNo 3??H 2SO 4 | ????0.1～1 ????5～15 | ????5～10 | ????2～3 | Golden yellow | The yellow that green flavor is arranged in the golden yellow, cost an arm and a leg, raw material is difficult for buying |
| ??KmnO 4??H 2SO 4 | ????10～30 ????10～20 | ????6～12 | ????4～10 | Golden yellow | Inclined to one side beige of tone or khaki color, weather resistance is than silver salt difference |
| ??H 2SeO 3??H 2SO 4 | ????4.5 ????8.8 | ????10 | ????5 | Light yellow | Slightly red flavor does not have market because of look shallow |
| ??Na 2Mo 4H 2O ??H 2SO 4 | ????2～4 ????400～500 | ????8～15 | ????1～15 | Light yellow | Look too shallow, do not have marketable value |
What be worth emphasizing is, though AgNo
3, KmnO
4Deng the existing very long history of the golden series that is main salt, technology is also comparatively ripe, but has defective because of its tone, processing requirement is also strict, so never can open up markets, and oxysalts such as selenium, aluminium can't go out dark gold, equally do not have economic worth yet.What people comparatively liked on the existing market is the aluminium alloy extrusions of titanium-golden yellow alumium, usually the technical process of the colouring processing method that adopts is: oil removing, alkaline etching, neutralization, oxidation, electrolytic coloring, sealing of hole, air-dry operation, wherein the technology of electrolytic coloring is: the selenic acid of 4.5 grams per liters, 8.8 the sulfuric acid of grams per liter, the voltage of 8-12V, temperature 20-24 ℃, the time is 5 minutes, this mode can only go out light golden rod yellow, marketable value is relatively poor.At present in Chinese patent application number is a kind of eletrolytic colouring technology for golden colour aluminium alloy selenide of 96119433.3, the technology of its invention is for to have increased a reaming treatment process in anodic oxidation and electrolytic coloring operation, since by the reaming after stain just aluminium alloy type just can reach dark golden yellow, but it is also not ideal enough at oxide film wear resisting property and sealing quality, and also slightly weaker aspect stable, and increased operation and cost increases.
The object of the present invention is to provide a kind of acquisition have pure in colour, do not contain other raggle-taggle titanium-golden yellow alumium, good stability, the easy titanium-golden yellow alluminium alloy of processing and working method.
For achieving the above object, titanium-golden yellow alumium alloy colouring processing method of the present invention, technical process comprise oil removing, alkaline etching, neutralization, oxidation, electrolytic coloring, sealing of hole, air-dry operation, and its electrolytic coloring cell liquid prescription is: the selenate of 0.5-20 grams per liter, the sulfuric acid of 8-16 grams per liter, the detonation suppressor of 15-40 grams per liter, 15-40 grams per liter conducting medium, the hydrogen inhibitor of 30-45 grams per liter, its skill parameter is: 25-80 ℃ temperature, the voltage of 8-22V, 0.5-6 minute time
The optimal slot liquid formula of electrolytic coloring operation of the present invention is: the selenate of 2-6 grams per liter, the sulfuric acid of 10-12 grams per liter, the detonation suppressor of 20-25 grams per liter, 20-25 grams per liter conducting medium, the hydrogen inhibitor of 40-45 grams per liter, its optimum process parameters is: 38-45 ℃ temperature, the voltage of 10-12V, 0.5-6 minute time.
Adopt above-mentioned method, owing in the electrolytic coloring operation, adopted middle temperature or pyritous processing condition, make cell liquid to the painted fast and dark effect of aluminium alloy extrusions, can painted color can be obtained from shallow to deep, the aluminium alloy extrusions that is obtained is magnificent titanium-golden yellow alumium, pure in colour, do not contain that other is variegated, good stability.
Titanium-golden yellow alumium alloy colouring processing method embodiment of the present invention, its technical process is: put on the shelf → oil removing → washing → alkaline etching → washing → neutralization → washing → oxidation → washing → electrolytic coloring → washing → sealing of hole → air-dry → pack.Oil removing is stream acid, 4 minutes the time of normal temperature of 170 grams per liters, alkaline etching is: the additive of the sodium hydroxide of 60 grams per liters, 20 grams per liters, 50 ℃ temperature, 2 minutes time, neutralization is pin acid, 2 minutes the time of normal temperature of 200 grams per liters, is oxidized to the sulfuric acid of 170 grams per liters, the A of 12 grams per liters
3+, 20 ℃ temperature, electrolytic coloring, tank liquor prescription, the tin anhydride of 5 grams per liters, the sulfuric acid of 10 grams per liters, the detonation suppressor of 25 grams per liters, the conducting medium of 25 grams per liters, the hydrogen inhibitor of 40 grams per liters, the voltage of 12V, 40 ℃ temperature, 90 seconds time, sealing of hole is: the additive of the 5 grams per liters (Ni of 1.0-1.5 grams per liter
2+, the 0.3-0.7 grams per liter F
-), 6 PH, time decides according to oxide thickness.Below according to the changing conditions test of temperature variation: tank liquor prescription and technology: the tin anhydride of 5 grams per liters to painted color, the sulfuric acid of 10 grams per liters, the detonation suppressor of 25 grams per liters, the conducting medium of 25 grams per liters, the hydrogen inhibitor of 40 grams per liters, exchange painted voltage 12V, during 25 ℃ of (1) temperature, 90 seconds painted time can obtain shallow golden sample; (2) during 40 ℃ of temperature, 90 seconds painted time can obtain golden yellow sample; (3) during 60 ℃ of temperature, 90 seconds painted time can obtain dark golden yellow sample; (4) during 30 ℃ of temperature, 180 seconds painted time can obtain golden yellow sample; (5) during 45 ℃ of temperature, 180 seconds painted time can obtain dark golden sample.More than test proves absolutely, temperature, high temperature coloring process are rationally being adjusted colour temperature and painted time in the employing, can obtain the good titanium color system product of property from shallow to deep, and can form batch process.
