Embodiment 1

[0014] A processing technology for making antique copper from aluminum, comprising the following steps:

[0015] (1) Degrease the surface of the aluminum part and clean it with 5% dilute hydrochloric acid, then rinse it with water and dry it;

[0016] (2) Copper-plate the surface of the processed aluminum parts, the thickness of the coating is 1mm;

[0017] (3) Soak the above-mentioned aluminum parts in chemical potion for 5 minutes, carry out coloring treatment, and then rinse with clean water. The chemical potion includes K 2 S25g / L, HNO 3 30mL / L, potassium permanganate 10g / L, copper oxide 25g / L;

[0018] (4) Brushing the colored aluminum parts;

[0019] (5) The surface of the aluminum part is sprayed with varnish, and after drying, the finished product is obtained.

Embodiment 2

[0021] A processing technology for making antique copper from aluminum, comprising the following steps:

[0022] (1) Soak and clean the aluminum parts in hot soapy water, then polish them with sandpaper with a particle size of 10-20 μm, and finally soak them in 5% dilute hydrochloric acid for 3 minutes, take them out, rinse them with clean water, and dry them;

[0023] (2) Copper-plate the surface of the processed aluminum parts, the thickness of the coating is greater than 0.5mm, and the surface of the aluminum parts is covered with a thin layer of copper;

Abstract

The invention belongs to the field of metal surface treatment, and particularly relates to a processing technology for manufacturing antique brass through aluminum. The processing technology for manufacturing antique brass through aluminum includes the following steps that (1) surface treatment is conducted on an aluminum piece; (2) surface copper plating is carried out; (3) the treated aluminum piece is put into a chemical solution to be soaked for 5-10 min, color coated treatment is performed, and then the aluminum piece is washed by clear water; (4) wiredrawing treatment is conducted on the colored aluminum piece; (5) varnish is sprayed on the surface of the aluminum piece, and after drying, a finished product is manufactured. According to the method, aluminum can be used for preparing antique brass, the processing technology is simple, the processing cost is low, aluminum and copper are both good in corrosion resistance, aluminum is low in cost compared with copper, and therefore the processing technology is beneficial to popularizing and applying antique brass.

Description

technical field [0001] The invention belongs to the field of metal surface treatment, and in particular relates to a processing technology for making antique copper from aluminum. Background technique [0002] Copper was called red gold in ancient China, because its surface has a strong metallic luster, so one of the main uses of copper is architectural decoration. With the evolution of history, the use of copper decoration products is not limited to doors and windows, but has been widely infiltrated into various sections of architectural decoration, especially the curtain wall copper decoration system, which has already sprouted in high-end buildings. Copper decorative curtain walls include copper doors, copper windows, copper canopies, copper decorative panels, copper window covers and various copper shapes. Copper and some of its alloys have good corrosion resistance and are stable in dry air, so copper ornaments have become the darling of high-end buildings. Copper can...
