Abstract
An imitation stainless steel treatment technology on the surface of aluminum alloy material comprises the following steps: a) decontamination; b) wire drawing on the surface; c) electrolytic degreasing; d) sulfate immersion cleaning; e) electrophoretic coating; f) drying after coating. In c), the electrolytic degreasing liquid used is sodium phosphate of the concentration of 50 to 55 percent; thevoltage is 5 to 8 volt; the degreasing time is 2 to 3 minutes. In d), the concentration of the sulfate is 5 to 10 percent; the time of the immersion cleaning is 30 seconds to 50 seconds. In e), the electrophoretic paint is polyurethane paint and the coating time is 10 to 60 seconds. The drying temperature is 70 to 80 DEG C; the drying time is 25 to 40 minutes in f). The invention can process the surface of aluminum alloy material to have the exterior color of stainless steel, thus greatly improving the decorativeness.
Description
Technical field
The present invention relates to a kind of metal material surface treatment process, relate in particular to a kind of surperficial processing process of imitated stainless steel of aluminum alloy materials.
Background technology
Aluminium alloy is one of material of extensively adopting of building decoration field, has characteristics such as light weight, low price, starting material source are wide.But existing aluminum alloy surface treatment technology can only obtain silvery white and copper-colored outward appearance, and the surface is bright inadequately attractive in appearance, has influenced the decorative effect of aluminium alloy.
Summary of the invention
Technical problem to be solved by this invention provides a kind of process of surface treatment of aluminum alloy materials, makes aluminum alloy surface have stainless exterior decorative effect.
For this reason, the invention provides a kind of simulation stainless steel process technique for aluminum alloy material surface, may further comprise the steps:
A) clean decontamination;
B) surperficial wire drawing;
C) electrolytic degreasing; Used electrolytic degreasing liquid is 50%～55% sodium phosphate, and voltage is 5V～8V, and the oil removing time is 2～3 minutes;
D) sulfuric acid embathes; Used sulfuric acid concentration is 5%～10%, and the time of embathing is 30～50 seconds;
E) electrophoretic painting; Used electrocoating paint is the Polyurethane lacquer, and the japanning time is 10～60 seconds;
F) be coated with the back oven dry; Bake out temperature is 70 ℃～80 ℃, and drying time is 25～40 minutes.
Described surperficial wire drawing can be made straight burr, random line or ripple according to decorating needs.
Beneficial effect of the present invention is and aluminum alloy materials can be processed into the stainless steel appearance color, makes its ornamental greatly raising.
Embodiment
Embodiment 1
Al alloy parts processes the straight line lines at workpiece surface with the method for mechanical friction after cleaning the decontamination operation and removing surface contaminants.Subsequently workpiece is carried out electrolytic degreasing and handle, used electrolytic degreasing liquid is 50% sodium phosphate, and voltage is 5V, 3 minutes oil removing time, after the oil removing workpiece is washed.The sulfuric acid of employing 8% soaked 30 seconds workpiece, thoroughly embathed in pure water afterwards to guarantee the cleaning of workpiece.Workpiece is immersed in the paint tank of Polyurethane lacquer and be hung on the negative electrode, the japanning time is 60 seconds.After being coated with workpiece is placed in about 70～80 ℃ baking oven, dried 30 minutes, coating is fully hardened.In temperature-rise period, coating can flow smooth automatically, and the gloss that becomes is transparent, forms a kind of decorating film of uniform stainless steel effect on the Al alloy parts surface.
