CN103774191A - Copper plating method of leaf carving artware - Google Patents

Abstract

The invention provides a copper plating method of leaf carving artware. According to the copper plating method, a modern electroplating process is perfectly combined with the leaf carving artware and then copper plated artware from nature but higher than nature is fabricated, and as a result, the leaf carving artware is better in color, more beautiful, and higher in collection and market values.

Description

A kind of copper electroplating method of leaf carving handicraft article

Technical field

The present invention relates to a kind of artwork working method, specifically a kind of copper electroplating method of leaf carving handicraft article.

Background technology

At present, leaf carving handicraft article is as a kind of emerging artwork, there is the artistic expressions such as etching, microscopic carvings, paper-cut, adopt the natural form of blade, skilful at natural, outstanding interest and charm, let nature take its course to show the scene of the Nature wonderful workmanship excelling nature and the harmony between man and nature, make works come from from however higher than nature.But the artwork that current leaf carver skill is made is only natural blade color, color is single, lack aesthetic feeling.

Summary of the invention

Object of the present invention overcomes above deficiency exactly, and a kind of copper coating on leaf carving handicraft article is provided, and makes leaf carving handicraft article color better, has more aesthetic feeling.

Method of the present invention is:

1), take out soaking half a minute in the leaf carving handicraft article input concentration 0.25mol/L stannous chloride solution of making;

2), the leaf carving handicraft article of taking-up is cleaned up in clear water;

3), separately get a container, put into the silver nitrate solution of concentration 2%, slowly splash into the ammoniacal liquor of concentration 2%, until the initial precipitation producing is dissolved just;

4), by clean clean leaf carving handicraft article put into and splash into concentration 35% formaldehyde solution 1ml, after 2 minutes take out, wash;

5), in container, add concentration 10% copper-bath, add again 5ml sulfuric acid, the petiole of leaf carving handicraft article is wound around and makes negative electrode with thin copper wire, and copper rod is made anode, when plating, after connecting 12 volts of power supplys of low pressure with wire, put into copper/saturated copper sulphate solution, power-on switch, electric current regulates by variable resistor, and the large I of electric current is regulated by distance between leaf carving handicraft article and copper rod, should be controlled between 0.5-1 ampere electroplating time approximately 10 minutes.

6), take out leaf carving handicraft article and clean and dry pressing, can obtain exquisite copper facing leaf carving handicraft article.

The invention has the beneficial effects as follows: leaf carving handicraft article is more attractive in appearance, there is stronger visual effect and reserve value.

Embodiment

Below in conjunction with embodiment, the present invention is described in further detail, but does not form any limitation of the invention.

Embodiment:

By 100 of the leaf carving handicraft articles of making, in input concentration 0.25mol/L stannous chloride solution, soak half a minute and take out.Take out leaf carving handicraft article with instrument cleans up in clear water.Separately get a container, put into the silver nitrate solution of concentration 2%, slowly splash into the ammoniacal liquor of concentration 2%, until the initial precipitation producing is dissolved just.Put into and splash into concentration 35% formaldehyde solution 1ml by cleaning clean leaf carving handicraft article, after 2 minutes, take out, wash.In container, add concentration 10% copper-bath, add again 5ml sulfuric acid, the petiole of leaf carving handicraft article is wound around and makes negative electrode with thin copper wire, and copper rod is made anode, when plating, after connecting 12 volts of power supplys of low pressure with wire, put into copper/saturated copper sulphate solution, power-on switch, electric current regulates by variable resistor, and the large I of electric current is regulated by distance between leaf carving handicraft article and copper rod, should be controlled between 0.5-1 ampere electroplating time approximately 10 minutes.Taking-up leaf carving handicraft article is cleaned and is dried pressing, can obtain exquisite copper facing leaf carving handicraft article.
