Problems solved by technology

The coloring color system of cold coloring is relatively single, and basically only deep and light bronze colors can be produced. The coloring color system of hot coloring is very wide, and many complex color systems can be produced, but the disadvantage is that the surface temperature of the coloring product is difficult to control, and the coloring effect is not good. The color difference between different products of the same color system is relatively large, and it has a greater relationship with climate change

Embodiment Construction

[0043] Specific embodiments of the present invention will be described in detail below.

[0044] A process method of constant temperature black, brown, maroon on the bronze surface, the bronze material involved, specifically refers to 313 copper alloy formula (Cu is 84%, Zn is 3.%, Sn is 13%) and C90300 copper alloy formula ( Cu is 86.0-89.0%, Zn is 3.0-5.0%, Sn is 7.5-9.0%), and it is realized through the following process:

[0045] 1. Black

[0046] 1. The formula of soaking chemical test solution

[0047] In glassware, add 5g of potassium persulfate and 50g of sodium hydroxide per liter of distilled water, then add JFC with 4% of the total test solution mass; or, add 10g of potassium persulfate and 45g of sodium hydroxide per liter of distilled water, and then add the total test solution 3% JFC by mass; or, add 15g potassium persulfate and 55g sodium hydroxide per liter of distilled water, then add 2% JFC by mass of the total test solution; stir well and set aside.

Abstract

The invention discloses a method for coloring stable black, brown and chestnut colors on the surface of a bronze artwork at constant temperature. The bronze material of the bronze artwork specifically refers to the 313 copper alloy formula and the C90300 copper alloy formula. By dipping three different reagents, Achieve constant temperature stable coloring. The color attached by this coloring process is uniform and stable, especially achieving the effect that the surface color of the bronze artwork is very stable for several years.

Description

technical field [0001] The invention belongs to the technical field of art casting coloring, and relates to a process method for coloring at a constant temperature on the surface of a bronze sculpture, in particular to a method for coloring stable black, brown and chestnut colors at a constant temperature on the surface of a bronze artwork. Background technique [0002] At present, in the art casting industry, the mainstream coloring processes mainly include cold coloring for coloring at room temperature; hot coloring for chemical coloring by spraying relevant chemical reagents while heating. The coloring color system of cold coloring is relatively single, and basically only deep and light bronze colors can be produced. The coloring color system of hot coloring is very wide, and many complex color systems can be produced, but the disadvantage is that the surface temperature of the coloring product is difficult to control, and the coloring effect is not good. The color differ...
