The copper-aluminum composite decorative plate is made of 1060 series aluminum alloy and T2 pure copper plate. Generally, an aluminum plate is subjected to sheet metal processing technologies such as blanking, stamping, bending, welding, polishing and the like to form a required product shape, but the existing welding technology has technical defects for composite materials, so that a new forming technology angle forming technology is adopted. The whole corner forming process comprises the following steps: blanking, punching four corners, bending and forming the corners. Punching the four corners of the plate after the plate is cut to form four-side chamfer notches, bending the four sides of the plate, punching the horn mouth into an arc by using a corresponding die, cutting off redundant materials, and finally drawing the copper surface. And after the metal plate is machined, sequentially carrying out an acid pickling coloring process and a spraying process. The pretreatment process mainly comprises the following steps: degreasing a copper-aluminum composite board by using a degreasing agent, removing residual degreasing agent by using first washing, removing oxides by using an acid pickling polishing solution to enable the surface of copper to be glossy, removing residual acid pickling polishing solution by using second washing, passivating the copper-aluminum composite board by using a chromium passivation solution, removing residual passivation solution by using third washing, coloring the copper-aluminum composite board (16 colors can be generated at most according to different color requirements), washing residual coloring agent by using fourth washing, and removing residual clear water on the board surface by entering a first baking process, so that the pretreatment process is completed; the spraying process is to spray a fluorocarbon resin varnish layer, to pass through a leveling procedure, and then to bake the fluorocarbon resin varnish layer for 10min to 15min at 220 ℃ to 250 ℃ so as to cure the whole plate surface coating.
The copper-aluminum composite plate angle forming process is formed through a specific angle forming die. Compared with the traditional aluminum plate, the copper-aluminum composite welding method has the large problem in welding, so that the angle stamping mode is adopted, the angle stamping benefit is that only the angle is stamped, the shape of the plate can be changed, the stamping forming is not influenced, the compatibility is high, and the method is simpler and more convenient. The corner forming process comprises the following steps: punching and shearing four corners of the plate, bending and forming the four corners conveniently on the next step, forming the horn mouth shape only by the remaining four corners, punching the horn mouth shape of the four corners into an arc shape by utilizing a punching die, and cutting off redundant materials. The copper-aluminum composite plate needs to be molded through an angle molding process, the roughness of the surface of the copper-aluminum composite plate needs to be improved through a wire drawing process before spraying, so that the adhesive force of a paint film on the copper-aluminum composite plate is improved, the copper-aluminum composite plate needs to be degreased by alkali washing, oxide is removed by acid washing and polishing and chromizing before spraying to form a protective passivation film, and the surface of the treated copper-aluminum alloy plate achieves the purpose of corrosion prevention of a base material by washing out treatment liquid residues with clear water, so that the treated surface effect can meet the requirement of fluorocarbon spraying, and fluorocarbon paint can be attached to the surface of the copper-aluminum composite plate to the maximum extent.
The passivation film is formed by spraying passivation solution on the surface of the copper-aluminum composite board to form a compact passivation film, the formed passivation film can protect the metal surface and improve the corrosion resistance of the metal plate, and can improve the adhesive force of the fluorocarbon paint layer to the aluminum substrate, and the thickness of the passivation film is about 5 microns. The fluorocarbon resin varnish layer is a normal-temperature curing type two-component colorless transparent varnish layer with fluorocarbon resin as a main component, so that the performances of corrosion resistance, mildew resistance and ultraviolet resistance of the product are further improved, and finally, the surface glossiness of the product is kept unchanged for a long time.
The coloring is to endow the copper-aluminum composite board with different colors in a chemical reagent mode, and the color can be more than 10. Using the commonly used ancient verdigris (malachite green), the following solutions were used for coloration:
5-35 g/L hydrochloric acid (HCl),
5-120 g/L of copper acetate (Cu (AC)2),
2-100 g/L basic copper carbonate (Cu2(OH)2CO3),
5-30 g/L of copper nitrate (Cu (NO)2),
5-150 g/L ammonium chloride (NH4CL),
30-180 g/L of sodium chloride (NaCL).
The solution with 200-300 ml per square is needed, and the drying can be repeated for a plurality of times, so that the malachite green with excellent binding force can be obtained.
The fluorocarbon resin varnish layer is a colorless and transparent varnish layer which takes fluorocarbon resin as a main component, and is coated on the thin copper decorative surface to achieve the purposes of oxidation resistance, corrosion resistance improvement and gloss retention, and the thickness of the formed varnish layer is about 15 mu m.
The invention has the beneficial effects that the copper and the aluminum are compounded together for the first time, and a feasible forming process scheme is obtained by comprehensively considering the characteristics of the copper and the aluminum. The copper can show the historical vicissitudes sense of the building, compare in the aluminium veneer more atmospheric weight, compare in pure copper and economical and practical, greatly enriched the product chain of the curtain trade, provide more choices for the designer.
