Abstract
The aluminium section material body produced by means of the processes of aluminium surface treatment, composite colouring and electrophoresis process is mainly characterized by that on the basis of traditional process of new process of adding a layer of colour-fixing film outside pigment precursor layer so as to overcome the defect of dull product colour due to pigment decolourization and diffusion produced at the time of electrophoresis process. It is applicable to production of aluminium section material products with bright colours, such as colour aluminium alloy door and window.
Description
The present invention relates to a kind of aluminium section material body of producing through aluminium surface treatment, composite coloration, electrophoresis process.
Aluminium composite coloration technology in the past, because the direct electrophoresis in the painted back of organic pigment body and part inorganic pigment body, solvent and amine matter generation rapid reaction with in the electrophoresis liquid cause chromatoplast to fold diffusion fast, chromatoplast is separated out and is polluted electrophoresis liquid.
First purpose of the present invention is: provide and can avoid chromatoplast to separate out, thereby be formed with the novel building aluminium section bar body of distinct pigment.
Second purpose of the present invention is: provide the fast light value that can have These characteristics good aluminium section material body.
The 3rd purpose of the present invention is: the aluminium section material body that the color of the compliance with environmental protection requirements that can have These characteristics is provided.
The 4th purpose of the present invention is: the aluminium section material body that can have These characteristics manufacture method is provided.
First purpose of the present invention is achieved in that a kind of aluminium section bar body, it comprises that the inorganic or organic pigment body layer (3) that forms anode oxidation membrane (2), adsorption coloring on the surface of aluminum substrate (1) is characterized in that: also have fixation rete (4), electrophoretic paint rete (5) outside layer (3).The effect of fixation rete (4) is with surperficial topped, the sealing of pigmentary layer (3), and it is kept apart with electrophoresis liquid when electrophoresis, is unlikely to molten by electrophoresis liquid, separates out and spread, and layer (3) has been played the effect of protecting; Every adhesion layer effectively (3) and layer (5) can not destroy them again, simultaneously can be not molten by electrophoresis liquid yet, separate out and destroyed material all can be used as the material of layer (4), for example: middle high temperature on sale does not on the market have fluorosulfuric acid Ni fixation encapsulant (Guangdong Nanhai County, South Sea sail chemical industry company limited produces, model: the MA-99 fixative).The effect of electrophoretic paint rete (5) be its surface of protection with aluminum substrate (1) between each layer and make aluminium type surface and effect that corrosion-resistant and glossiness increases, therefore, every coating with this effect is in this scope (the vinylformic acid electrophoretic paint is first-selection) all.
Such scheme of the present invention can be done following perfect: between layer (2) and layer (3) electrolytic metal settled layer (6) is arranged, the material of layer (6) can be that light green adopts Silver Nitrate etc., and the effect of layer (6) is to strengthen the fast light value that the sun-proof function of composite coloration layer improves film.It is can adopt nontoxic blackish green material according to what the requirement of national environmental protection department designed that organic pigment body layer (3) adopts cyan organic pigment body layer, for example: the used blackish green chromatoplast of building aluminum alloy doors and windows that is used for outdoor use.Electrophoretic paint rete (5) adopts vinylformic acid electrophoretic paint rete effect better.
The 4th purpose of the present invention can realize like this: a kind of manufacture method of aluminium section bar body, it is characterized in that: the surface at aluminum substrate (1) forms oxidation film layer (2) through anodic oxidation, then, the countless micropore surfaces that make chromatoplast be deposited on oxidation film layer (2) through adsorption form the chromatoplast layer (3) that adheres to, outside layer (3), form fixation rete (4) through chemical deposition process again, at last, through electrophoresis process, make electrophoretic paint outside film (4), form the electrophoretic paint rete (5) of the surface smoothing that micropore is full of, seals.The anodic oxidation of above-mentioned layer (2), the painted absorption of layer (3), the electroless plating of layer (4) all is respectively traditional technologys, the attachment means of layer (5) also is traditional electrophoretic method substantially, its way is: utilize the organic electrochemistry method, adopt electrolysis, electrophoresis, galvanic deposit, electrodialysis and high-temperature cross-linking sclerosis.
Aforesaid method of the present invention can be done following perfect: forming organic chromatoplast layer (3) before, making metal-salt (for example: Silver Nitrate) be deposited on formation electrolytic metal settled layer (6) outside the surperficial micropore of layer (2) with the alternating-current solution.To improve the sun-proof degree of aluminium section bar body.
The present invention has mainly adopted increases one deck fixation rete (4) outside the chromatoplast layer, to be that electrophoresis liquid is separated in chromatoplast layer and the electrophoresis process effectively, thereby overcome traditional product in electrophoresis because its production technique can't solve chromatoplast and emanate fast, spreads, cause product both to lose distinct color, pollute the defective of electrophoresis liquid again aborning; The present invention also provides to realizing the method for products production.

Fixation film (4): middle high temperature does not have fluorosulfuric acid Ni fixation encapsulant, and (South Sea, Guangdong city, South Sea sail chemical industry company limited produces, model: the MA-99 fixative).
Electrophoretic paint rete (5): water-soluble acrylic resin coating.
Electrolytic metal salt pigmented layer (6): Silver Nitrate.
The technological process of production:
Aluminum substrate (1) is handled: oil removing, washing-alkaline etching, washing, bright dipping-electrolytic oxidation (anodic oxide coating (2) moulding)-washing-electrolytic coloring (electrolytic metal salt pigmented layer (6) moulding), washing-adsorption coloring (organic pigment body layer (3) moulding), washing-fixation film (4) moulding, drying, washing, hot water wash, pure water wash-electrophoresis (electrophoretic paint rete (5) moulding), pure water wash twice, dry, cool off, check.
