Copper painting sintering process

Abstract

The invention discloses a sintering technology for a copper picture. The sintering technology for the copper picture comprises the technological processes that firstly, a pattern is chiseled or engraved in the surface of a red copper utensil; then dimpled grains of the pattern are coated with a self-made pasty copper-zinc alloy blender, the pattern part is heated with an electric furnace and an oxygen welding gun at the same time, and copper alloy powder is naturally smelted in the dimpled grains of the copper picture; afterwards, the surface of the pattern is abraded, polished and cleaned; and finally the copper utensil is completely soaked in a potassium sulphide solution to be subjected to coloration treatment, and the pattern is completely presented. The copper picture manufactured through the sintering technology has metal lines and shows up the natural color of metal. The whole pattern part is well defined in boundary, is pure in color and never fades. According to the sintering technology, pictures composed of points, lines and planes can be sintered, and rich colors such as golden yellow, silvery white and elegant black can be obtained.

Description

technical field [0001] The invention relates to a process for metal surface pattern treatment, in particular mainly relates to a copper painting sintering process, which can also be used for sintering of gold, silver, iron, tin and other metal surface patterns. Background technique [0002] Surface pattern treatment of copper utensils from ancient times to the present: there are natural color smooth treatment, chiseled pattern treatment, gilding, interlaced gold and silver treatment, cloisonne, enamel treatment, etc.; the effect of copper painting sintering process and interlaced gold and silver process is the closest , the use of the wrong gold and silver process on bronze ornaments, its general method is the mosaic method, the performance effect is to engrave the copper surface, insert gold and silver wires, pieces, hammer it firmly, and then polish it smooth with alabaster to achieve outstanding The decorative effect of the pattern; but the closest to this craft is its ot...

Problems solved by technology

[0002] Surface pattern treatment of copper utensils from ancient times to the present: there are natural color smooth treatment, chiseled pattern treatment, gilding, interlaced gold and silver treatment, cloisonne, enamel treatment, etc.; the effect of copper painting sintering process and interlaced gold and silver process is the closest , the use of the wrong gold and silver process on bronze ornaments, its general method is the mosaic method, the performance effect is to engrave the copper surface, insert gold and silver wires, pieces, hammer it firmly, and then polish it smooth with alabaster to achieve outstanding The decorative effect of the pattern; but the closest to this craft is its other method: the mud gold method, which uses the "mixture" of gold, silver and mercury as the raw material, which is applied to the surface of the copper ware, and then baked with charcoal to evaporate the mercury , the gold is attached to the surface of the vessel and does not come off, and a complete gold and silver bronze work is often completed after 4 to 6 processes, and it takes a lot of money to complete.

[0003] With the improvement of people's living standards, people's aesthetic level is also constantly improving. The surface treatment of copper ware is more and more popular because of the above characteristics. In terms of relationship, they are not accessible to the audience; on the other hand, the use of heavy metal mercury increases the pollution of the environment
