Embodiment 1

[0019] The colored liquid of spotted copper described in this embodiment is prepared from the following raw materials: 10 parts by weight of copper sulfate, 6 parts by weight of potassium chloride, 4 parts by weight of potassium borate, 1 part by weight of cinnabar, and 150 parts by weight of distilled water.

[0020] The coloring solution described in this embodiment is used to prepare spotted copper, which specifically includes the following steps:

[0021] (1) Grinding the copper-zinc alloy casting with a copper content of 93wt% with sandpaper to ensure that the surface of the casting is smooth and free of pits, soaking it in hydrochloric acid with a concentration of 10mol / L to remove the surface oxide layer, and then cleaning the casting;

[0022] (2) Put the cleaned casting into a spot solution with 8.1wt% ferric chloride, 9.6wt% hydrochloric acid, and 0.8wt% potassium chloride to corrode for 5 minutes, and spots of different sizes will appear on the casting. Then, the ca...

Embodiment 2

[0026] The colored liquid of spotted copper described in this embodiment is prepared from the following raw materials: 13 parts by weight of copper sulfate, 9 parts by weight of potassium chloride, 8 parts by weight of potassium borate, 2 parts by weight of cinnabar, and 180 parts by weight of distilled water.

[0027] The coloring solution described in this embodiment is used to prepare spotted copper, which specifically includes the following steps:

[0028] (1) Grinding the copper-zinc alloy casting with a copper content of 95wt% with sandpaper to ensure that the surface of the casting is smooth and free of pits, soaking it in sulfuric acid with a concentration of 11mol / L to remove the surface oxide layer, and then cleaning the casting;

[0029] (2) Put the cleaned casting into a spot solution with 7wt% ferric chloride, 10wt% hydrochloric acid, and 0.5wt% potassium chloride for 8 minutes, and spots of different sizes will appear on the casting. Clean the castings after stai...

Embodiment 3

[0033] The colored liquid of spotted copper described in this embodiment is prepared from the following raw materials: 16 parts by weight of copper sulfate, 13 parts by weight of potassium chloride, 10 parts by weight of potassium borate, 3 parts by weight of cinnabar, and 300 parts by weight of distilled water.

[0034] The coloring solution described in this embodiment is used to prepare spotted copper, which specifically includes the following steps:

[0035] (1) Grinding the copper-zinc alloy casting with a copper content of 97wt% with sandpaper to ensure that the surface of the casting is smooth and free of pits, soaking it in hydrochloric acid with a concentration of 12mol / L to remove the surface oxide layer, and then cleaning the casting;

[0036] (2) Put the cleaned casting into a spot solution with 9wt% ferric chloride, 8wt% hydrochloric acid, and 1wt% sodium chloride for 10 minutes, and spots of different sizes will appear on the casting. Clean the castings after spo...

Abstract

The invention discloses a spot-bronze coloring liquid and an application thereof, and belongs to the field of metal material surface treatment and handicraft making. The coloring liquid is prepared by using the following raw materials, by weight, 10-20 parts of copper sulfate, 6-15 parts of potassium chloride, 1-4 parts of potassium borate, 4-12 parts of cinnabar and 150-300 parts of distilled water. The coloring liquid is used in spot-bronze production to obtain dark red spot-bronze, and spot-bronze obtained in the invention has unsophisticated and beautiful appearance; the color of the spot-bronze can be controlled according to the time length and personal preference, and can be dark or brilliant, and the preparation process is flexible and controllable; the obtained spot-bronze has the characteristics of stability, and no color change or fading; and a making method of the spot-bronze has the advantages of simple operation, low production cost, non-restriction by the shape of a product, and beautiful color of the product.

Description

technical field [0001] The invention relates to a colored liquid of spotted copper and its application, which belongs to the field of surface treatment of metal materials and handicraft production. Background technique [0002] Bornite is a unique brass in Yunnan. It is made of high-grade copper-based alloy materials through modeling design, casting, precision grinding and other complicated follow-up processes. It has patterns of mixed shapes and colors. Spots are the most valuable feature of spotted copper. The spotted spots appearing in the copper base material make spotted copper handicrafts have a wonderful color of red spots and golden yellow. It is a special craft unique to China. Its brownish-red surface, showing the markings, has a simple, simple and elegant feeling, and it can be called the crown of metal crafts. Its surface shows a variety of irregular magnificent patterns and golden and red interlaced colors. It is a unique folk traditional handicraft in Yunnan P...
