Embodiment 1

[0019] Embodiment 1: a kind of coloring solution that is chemically coated with copper green on the outer surface of a copper product according to the present invention, the components and content of the coloring solution are: 10% NH 4 Cl, 5% CuSO 4 , 1%CH 3 COOH, 2% accelerator and 82% H 2 O. By containing 10% NH 4 Cl, 5% CuSO 4 , 1%CH 3 COOH, 2% accelerator and 82% H 2 The coloring solution composed of O is coated on the surface of copper products, and the accelerator can accelerate the vulcanization, shorten the vulcanization time, lower the vulcanization temperature, and reduce the amount of vulcanization agent. Because the raw materials are easy to obtain and the price is affordable, the cost of the coloring solution is low and the efficiency is high. At the same time, the surface of the final copper product is rich in color, bright and consistent, with various effects and easy construction.

Embodiment 3

[0035] Embodiment three: a kind of copper product outer surface of the present invention is chemically covered with copper green coloring liquid, the component and content of described coloring liquid are: 15%NH 4 Cl, 8% CuSO 4 , 2%CH 3 COOH, 5% accelerator and 70% H 2 O. By containing 15% NH 4 Cl, 8% CuSO 4 , 2%CH 3 COOH, 5% accelerator and 70% H 2 The coloring solution composed of O is coated on the surface of copper products, and the 5% accelerator can better promote the vulcanization, shorten the vulcanization time, lower the vulcanization temperature, and reduce the amount of vulcanization agent. Because the raw materials are easy to obtain and the price is affordable, the cost of the coloring solution is low and the efficiency is high. At the same time, the surface of the final copper product is rich in color, bright and consistent, with various effects and easy construction.

Abstract

The invention discloses coloring liquid for chemically coloring copper green on an outer surface of a copper product. The coloring liquid comprises the following components: 10-30% of NH4Cl, 5-15% of CuSO4, 1-10% of CH3COOH, 2-15% of accelerator and 30-82% of H2O. The coloring method comprises the following steps: (1) the matched NH4Cl, CuSO4, CH3COOH and accelerator are added in H2O for fully mixing to form the coloring liquid; (2) the polishing or the sand blasting is firstly performed for the outer surface of the copper product to remove copper oxide on the surface; and then, the outer surface is brushed to remove floating ash; (3) the coloring liquid is uniformly coated on the outer surface of the copper product; (4) the coloring liquid remained on the outer surface is removed; (5) the outer surface coated with the coloring liquid is dried after standing; and (6) fluorocarbon varnish is sprayed to the dried surface for isolating air and ultraviolet rays to protect a coloring film. The coloring liquid can achieve the artware requirement, is uniform and bright in shown color, is simple and pure in component, can reduce the cost, and is higher in efficiency.

Description

technical field [0001] The invention belongs to the field of nonferrous metal processing, and in particular relates to a coloring solution for chemically coloring copper green on the outer surface of copper products and a coloring method thereof. Background technique [0002] The surface of the sculpture made of metal presents the color of the matrix, but the color of the matrix is ​​not rich enough, there is no sense of hierarchy, and the required artistic effect cannot be achieved. Although in the prior art, there is also the use of applying coloring liquid on the metal surface so that the artwork or sculpture finally presents color. However, the color of the coloring solution in the prior art is not pure enough after coloring, because it contains a variety of substances to react, so that the final color will be inconsistent or uneven and have different shades. Contents of the invention [0003] Purpose of the invention: In order to overcome the deficiencies in the prio...
