Abstract
The invention discloses a fading proof process for aluminum alloy electrophoresis titanium gold. The process is characterized by comprising degreasing, alkaline etching, oxidation, electrolytic coloring for 7-12 min at 25-35 DEG C, moderate temperature sealing at 45-60 DEG C for 1-3 min, hot water washing, electrophoresis with voltage of 120-140 volt and curing. The electrophoresis titanium section produced by the invention does not show a color shallowing problem after electrophoresis baking or a fading problem in a usage process, and has good popularization value.
Description
Technical field
The present invention relates to the aluminium alloy extrusions production technical field, especially relate to a kind of aluminium alloy extrusions electrophoresis titanium golden technology.
Background technology
In duraluminum electrolysis coloring process, use at present and roughly have three types comparatively widely.The one, stannous sulfate, single nickel salt list salt or two salt electrolytic coloring.This is the colour system of a kind of color from imitative steel look → champagne → bronze-colored → black.Next is the selenite electrolytic coloring, and colour system is a kind of color of similar gold, is called the titanium look.At last a kind of is the permanganate electrolytic coloring, and colour system is golden yellow.The painted degree-of-difficulty factor of selenite is bigger in these three kinds of coloring modes.The main problem that exists is the colouring difficulty, but color can't fade through washing again after dark partially, and is painted different fully with stannous sulfate, secondly is in the electrophoresis bake process, to fade to shoal, and makes to produce and goes up difficult control.More bad is in use also to find to fade, and color fades away fully when serious, makes client and manufacturer all suffer serious economy loss.For this reason; Person skilled is improved traditional duraluminum electrophoresis titanium look technology; Like one Chinese patent application number is CN99117173.X, and denomination of invention is the working method of electrophoretic titanium-golden yellow alluminium alloy section material, a kind of working method of electrophoretic titanium-golden yellow alluminium alloy section material; Its technical process comprises oil removing, alkali erosion, neutralization, oxidation, electrolytic coloring, anodic electrophoresis, draining, air-dry operation, and the voltage in processing parameter is 14-22V.Though; Reducing electrophoretic voltage can prevent to fade owing to overtension produces coloring ion generation acting in opposition; But this can only guarantee that the change of color is little behind the electrophoresis, can not fundamentally solve the lustful material problem of fugitive color in use.As everyone knows, the painted main salt of titanium golden-selenite coloring mechanism is oxide compound whole color development and developing the color in sull; Stannous sulfate is then different, and it is by the direct reduce deposition colour developing of tin ion.Volume is big comparatively speaking for titanium chromatic colorant thing, and resistance is big, so painted comparatively difficulty all need be carried out activation treatment to the oxidation fenestra generally speaking.A kind of method is before the oxidation after stain, through acid sull to be carried out activation, and another kind is in painted groove, to reach the purpose that colouring speed is quickened in activation through the rising tank liquor temperature.But no matter adopt which kind of method all can make sull become loose, compactness descends.lustful material through the electrophoretic painting baking time because the sull density reduces, thermal stability descends, thereby fugitive color, even in use also can take place.Because the activity of selenium and acid-respons is not forced to such an extent that section bar colouring in a single day just can not directly be faded through water-washing method, for this reason, be necessary to formulate a kind of novel process in addition to solve the problem that exists in the above-mentioned production technique.
Summary of the invention
The object of the invention is exactly that a kind of not only technology that provides for the deficiency that solves prior art is simple, easy to operate, and has improved the duraluminum electrophoresis titanium look fade-proof technology of performance of heat-resisting, the UV resistant irradiation of electrophoresis titanium section bar greatly.
The present invention adopts following technical solution to realize above-mentioned purpose: a kind of duraluminum electrophoresis titanium look fade-proof technology; It is characterized in that; Its technical process comprises oil removing, alkali erosion, oxidation, electrolytic coloring, middle temperature sealing of hole, hot water wash, electrophoresis and curing; Because longer then sull compactness of painted time is low more, the time of electrolytic coloring is 7-12 minute; In the warm sealing of hole time be 1-3 minute because the of short duration sealing of hole of middle temperature can carry out shutoff to a certain degree to painted oxidation fenestra, this can play the compactness that has increased sull, improves the effect of the resistance toheat of fenestra; Electrophoretic voltage is the 120-140 volt, can prevent to take off owing to overtension produces coloring ion generation acting in opposition.
As further specifying of such scheme, in the said electrolytic coloring process, the prescription of the cell liquid of employing comprises: selenous acid 5-7g/l, Trisodium Citrate 5-10g/l, tartrate 5-10g/l, boric acid 2-5g/l.
The temperature of said hot water wash is 80-150 ℃, and the time is 5-10 minute.
Preferred 9 minutes of said electrolytic coloring time.
Preferred 2 minutes of the warm sealing of hole time in said.
Electrophoresis is to adopt the anodic electrophoresis mode.
Said solidification process comprises draining process and air drying process.
The beneficial effect that the present invention adopts above-mentioned technical solution to reach is:
The present invention's warm sealing of hole and change the technology of painted time and electrophoretic voltage during we increase in novel process; Through increasing this two kinds of technologies; Improved the performance of heat-resisting, the UV resistant irradiation of electrophoresis titanium section bar greatly; Through the overaging accelerated test, defective fading do not appear in material yet, in use do not occur fading yet.
Embodiment
A kind of duraluminum electrophoresis of the present invention titanium look fade-proof technology; Its technical process comprises oil removing, alkali erosion, oxidation, electrolytic coloring, middle temperature sealing of hole, hot water wash, electrophoresis and curing; In the present embodiment, the time of electrolytic coloring is 7-12 minute, 25-35 ℃ of electrolytic coloring TR.Because longer then sull compactness of painted time is low more, therefore must shorten the painted time, the time that shorten just must increase tank liquor concentration, increases cost, take all factors into consideration we the painted time confirm 10 minutes with interior the most suitable, preferred 9 minutes.In the present embodiment, the prescription of electrolytic coloring tank liquor comprises:
Selenous acid 5-7g/l,
Trisodium Citrate 5-10g/l,
Tartrate 5-10g/l,
Boric acid 2-5g/l.
In addition; In the temperature of warm sealing of hole be 45-60 ℃, directly workpiece is soaked into tank liquor 1-3 minute, generally get 2 minutes comparatively suitable; 2 minutes of short duration sealing of hole can carry out shutoff to a certain degree to painted oxidation fenestra; This can play the compactness that has increased sull, improves the effect of the resistance toheat of fenestra, is crucial here; Secondly, reduce electrophoretic voltage and can prevent to fade owing to overtension produces coloring ion generation acting in opposition, but voltage is too low, gathering way of electrodeposited paint film will be greatly diminished, and confirms as 120-140 volt, preferred 130 volts through experiment.In addition, the temperature of hot water wash is 120 ℃, and the time is 8 minutes, and electrophoresis is to adopt the anodic electrophoresis mode, and solidification process comprises draining process and air drying process.
Above-described only is preferred implementation of the present invention, should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the invention design, can also make some distortion and improvement, and these all belong to protection scope of the present invention.
