BACKGROUND OF THE INVENTION
1. Field of the Invention This invention relates to a method for forming a pattern on a surface of an aluminum extrusion.
2. Description of the Related Art Aluminum extrusions are widely used in the architecture industry. However, since the aluminum extrusion has a monochromatic surface, the appearance thereof is dull and lacks aesthetic appeal.

According to the present invention, the method for forming a pattern on the surface of an aluminum extrusion comprises the steps of:
cleaning the surface of the aluminum extrusion by degreasing, caustic washing and pickling the aluminum extrusion;
forming a film on the cleaned surface of the aluminum extrusion;
providing a base color coating on the surface of the aluminum extrusion;

Figure 1 is a flow diagram showing the method for forming a pattern on a surface of an aluminum extrusion according to the present invention; and Figure 2 is a schematic view illustrating the equipment for printing the pattern on the surface of an aluminum extrusion according to the present invention.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to Figure 1, a preferred embodiment of the method for forming a pattern on a surface of an aluminum extrusion in accordance with the present invention is shown to comprise the steps of cleaning, film-forming, providing a base color coating, baking, washing, pattern-printing, and forming a protective film. In this embodiment, the pattern is in the form wood grains. The steps of the method for forming the pattern on the surface of the aluminum extrusion may be carried out right after the steps of the method for forming the aluminum extrusion in order to form and process the aluminum extrusion continuously. In addition; the method of the present invention can be performed a continuously on a conveyor device.
The cleaning step includes the step of dipping sequentially the aluminum extrusion into washing tanks which contain a surface-active agent, 1-500 of sodium hydroxide and 15-30% of nitric acid, respectively, in order to remove grease from the surface of the aluminum extrusion.
The cleaned aluminum extrusion is electrolyzed in a sulfuric acid solution in order to form an oxide film.
The sulfuric acid solution contains sulfuric acid having a concentration of 50-250 g/1, an aluminum ion concentration of 2-50 g/1, an electrolysis temperature of 10-30 °C, an electrolysis voltage of 5-25 volts, and an electric current density of 50-300 A/m2. The function of the oxide film is to provide a weather-proof effect to the aluminum extrusion.
A base color coating is provided on the film at the surface of the aluminum extrusion by electrodepositing an acrylic electrodeposition coating of a base color on the surface of the aluminum extrusion at a temperature of 0-50 °C. The concentration of the electrodeposition coating is 1-25 wt%. The base color coating can improve the appearance of the aluminum extrusion and protect the aluminum extrusion.
The aluminum extrusion is then baked at a temperature of 150-300 °C in order to crosslink and harden the base color coating.
Next, the base color coating of the aluminum extrusion is washed by an organic solvent in order to remove oil stains and dust therefrom.
After the base color coating has been washed with the organic solvent, a predetermined pattern, such as wood grains, is printed onto base color coating of the aluminum extrusion by means of the printing device, as best illustrated in Figure 2. The printing device has a power-driven metal roller 1 which has the wood grain pattern formed on an external face 11 thereof and which ' 98. 03. 10 (k) 16:42 SAINT ISLAN~A 02230942 i99s'-'0f-o4 886227316377 P.

Furthermore, a synthetic film may be formed on the cleaned surface of the aluminum extrusion instead of the oxide film by dipping the aluminum extrusion in a chromate solution, and the base color coating may be provided onto the surface of the aluminum extrusion by powder-coating an epoxy resin or polyethylene coating on the surface of the aluminum extrusion.
Moreover, the transparent protective film may be formed on the printed surface of the aluminum extrusion by applying an acrylic coating on the surface of the aluminum extrusion, and baking the acrylic coating.
Furthermore, in the step of forming the pattern on the surface of the aluminum extrusion, the printing device may comprise a plurality of metal rollers and polyurethane rollers for printing a plurality of sets of patterns onto the surface of the aluminum extrusion.
The metal and polyurethane rollers may be disposed around the entire surface of the aluminum extrusion in order to improve the printing efficiency.
While this invention thus explained, it is apparent that numerous modifications and variations can be made without departing from the scope and spirit of this invention. It is intended that this invention be limited only as indicated in the appended claims.
