Embodiment 1

[0009] Example 1: (1), select a copper product with a black surface to heat and dehumidify, and heat the surface of the copper product at a heating temperature of 70°C; (2), use a watering can to evenly spray copper nitrate solution on the surface of the copper product during heating 3 times, until blue appears on the surface of the copper product, the ratio of the copper nitrate solution is 7g: 1L water; (3), continue heating, and spray the ferric nitrate solution on the surface of the copper product with a watering can for 3 times, until the surface of the copper product appears ochre, The ratio of ferric nitrate solution is 8g: 1L water; (4), continue to heat, spray the surface of copper products with a watering can filled with ferric oxide solution, adjust the nozzle so that the solution sprayed from the watering can is columnar until the surface of copper products To obtain marble lines, the ratio of ferric oxide solution is 7g: 1L water; (5), continue to heat, and use a w...

Embodiment 2

[0010] Example 2: (1), select a copper product with a blue surface to heat and dehumidify, and heat the surface of the copper product at a heating temperature of 180°C; (2), use a watering can to evenly spray copper nitrate solution on the surface of the copper product during heating 4 times, until blue appears on the surface of the copper product, the ratio of copper nitrate solution is 18g: 1L water; (3), continue heating, and spray the ferric nitrate solution on the surface of the copper product with a watering can for 4 times, until the surface of the copper product appears ocher , the ratio of ferric nitrate solution is 20g: 1L water; (4), continue to heat, spray the surface of the copper product with a watering can filled with ferric oxide solution, adjust the nozzle so that the solution sprayed by the watering can is columnar until the copper product Marble lines are obtained on the surface, and the ratio of ferric oxide solution is 10g: 1L water; (5), continue heating, ...

Embodiment 3

[0011] Preferred embodiment 3: (1), select a copper product with a red surface and soak it in salt water for 3 minutes, heat and dehumidify, and heat the surface of the copper product at a heating temperature of 100°C; (2), heat the surface of the copper product during heating Use a watering can to evenly spray the copper nitrate solution 3 times until blue appears on the surface of the copper product. The ratio of the copper nitrate solution is 10g: 1L water; (3), continue heating, and use the watering can to spray the iron nitrate solution 4 times on the surface of the copper product. Until the surface of the copper product appears ochre, the ratio of the ferric nitrate solution is 10g: 1L of water; (4), continue heating, spray the surface of the copper product with a watering can filled with ferric oxide solution, and adjust the nozzle so that the watering can sprays The solution is columnar until marble lines are obtained on the surface of the copper product. The ratio of t...

Abstract

The invention discloses a coloring method of a copper product with marble stripes having strong layering sense and high glossiness. The method comprises the following steps: (1) selecting a copper product with a colored surface, heating and dehumidifying; (2) uniformly spraying cupric nitrate solution with a spraying can on the surface of the copper product during heating until the surface of the copper product is blue; (3) further heating, and spraying ferric nitrate solution toward the surface of the copper product with the spraying can until the surface of the copper product is ochre; (4) further heating, and spraying toward the surface of the copper product with a spraying can filled with ferroferric oxide solution until the marble line is obtained on the surface of the copper product; (5) further heating, and spraying titanium dioxide solution uniformly can to the surface of the copper product by using the spraying until white stripe is presented on the surface of the copper product; and (6) further heat, spraying ferric nitrate solution toward the surface of the copper product for 3-4 times with the spraying can until yellow-white stripe is presented on the surface of the copper product. The method has the beneficial effect that the copper product colored by the method is coherent in color, rich and stable.

Description

technical field [0001] The invention relates to a coloring method, in particular to a method for coloring marble stripes of copper products with strong layering and high gloss. Background technique [0002] Due to the particularity of copper material, copper craft products exposed to the air for a long time are prone to oxidation reaction, darken the color, produce oxide scales, and grow copper rust, which will affect the artistic effect, artistic style, aesthetic sense and appreciation of the crafts, so copper In the process of making handicrafts, the last process must be surface coloring. At present, there are mainly six coloring methods for copper handicrafts: hot coloring, cold coloring, buried coloring, wrapped coloring, smoked coloring and barrel dipping coloring, among which hot coloring and cold coloring are more representative. The color of cold coloring is monotonous, lacks personality and level, and cannot fully express the artist's thoughts and artistic level, a...
