Embodiment 1
[0031] Step (1). Copper surface treatment of copper products, the specific method is:
[0032] a. Use brass or red copper raw materials to make copper products according to product design requirements;
[0033] b. Surface pretreatment of copper products, pickling or sandblasting, and then polishing to product technical requirements;
[0034] c, make a rectangular concave sand mold with traditional sand box mould, plank the plank with length 80cm, width 40cm, thickness 2cm with the surface, surround four sides with high 20cm thick 2cm wooden strip above, make an upwards opening sand box.
[0035] d. Mix 80-100 mesh fine quartz sand with water at a ratio of 1:0.5, add a small amount of adhesive, and form a rectangular concave sand mold with a wall thickness of not less than 4cm. Tight, the bottom of the sand mold can be "leveled" with a spirit level;
[0036] Put it in the shade to dry (do not heat and dry, it is prone to uneven dryness and cracking), observe whether there is ...

Abstract
The invention discloses a preparation and technology method of a copper product with silver / gold in black copper on the surface. The preparation and technology method comprises the steps of proportionand manufacturing of the black copper and treatment of the silver / gold in the black copper on the surface. According to the preparation and technology method of the copper product with silver / gold inthe black copper on the surface, regular brass or red copper materials are adopted, the copper product has the effect of silver / gold in the black copper through a certain treatment method, the manufacturing technology of the method is simple, the surface of the copper product after treatment is jet-black and shiny, meanwhile chemical treatment modes are not adopted, the original features of the copper product are kept, patterns or decorative design parts are argentite or golden, a traditional effect of silver / gold in the black copper can be completely achieved, and the cost is low.
Description
technical field [0001] The invention belongs to the technical field of metal processing, and relates to a metal surface treatment method, in particular to a preparation and a process method of black copper and silver / gold on the surface of a copper product. Background technique [0002] The black copper silver / gold production process is a traditional folk metal craft in Yunnan. Black copper silver / gold is used to carve exquisite patterns on the copper embryo, and then silver or gold is plated in the intaglio pattern, and then the copper embryo The surface is processed into black by special process, so that it can set off golden or silver decorative patterns on the solemn and deep black background, making the craft products look graceful, luxurious, magnificent and colorful. Its shape is ingenious, its craftsmanship is exquisite, and its characteristics are rich. It not only has high artistic value and research value, but also has high commercial development value. Its crafts...
