Problems solved by technology

Bamboo, wood, flowers, plastics and other non-metals are all poor conductors of electricity and heat. Only when a layer of metal film is formed on the surface of the poor conductor can it be placed in the electroplating solution for electroplating. Therefore, how to pre-plating before electroplating A layer of good conductors is formed on the surface of flowers and leaves. As the underlying metal, there is currently no good pretreatment method

Embodiment 1

[0021] Take plant leaves, (such as leaves of ginkgo tree, etc.), first wash the leaves with water; then intrude into warm water at 15°C to open and expand the stomata of the leaves; remove the dirt accumulated in the stomata, and complete the pretreatment; The pretreated workpiece is immersed in a solution containing 10 g / l of stannous chloride and 10 ml / l of hydrochloric acid for electroless tin plating. After dipping, it is washed with water, so that a thin layer of tin coating can be formed on the workpiece. , and a part of the deposited tin is immersed in the pores of the workpiece. After electroless tin plating, the workpiece is immersed in an aqueous solution containing 0.2 g / l of palladium chloride and 2.5 ml / l of hydrochloric acid for surface activation treatment; then, the activated The workpiece is placed in the electroless nickel plating solution containing 30 g / l of nickel sulfate, 30 g / l of sodium citrate, and 50 g / l of ammonium chloride, and the pH value is adjust...

Embodiment 2

[0023] Get plant leaves (for example the leaves of ginkgo tree etc.), following steps are identical with embodiment 1, and the concentration etc. of its water temperature, solution are respectively: water temperature 20 ℃; Stannous chloride 8 grams / liter, hydrochloric acid 9 milliliters / liter; Chlorine Palladium chloride 0.15 g / L, hydrochloric acid 2 mL / L; nickel sulfate 25 g / L, sodium citrate 35 g / L, ammonium chloride 48 g / L, and the pH value was adjusted to 10.3.

Embodiment 3

[0025] Get plant leaves (for example the leaves of ginkgo tree etc.), following steps are identical with embodiment 1, and the concentration etc. of its water temperature, solution are respectively: water temperature 25 ℃; Stannous chloride 12 grams / liter, hydrochloric acid 10 milliliters / liter; Chlorine Palladium chloride 0.2 g / L, hydrochloric acid 2.8 mL / L; nickel sulfate 33 g / L, sodium citrate 25 g / L, ammonium chloride 52 g / L, and the pH value was adjusted to 10.8.

[0026] Electroplated plant leaves, because the surface is covered by corrosion-resistant metal plating, not only can perfectly retain the original shape details, such as the veins of plant leaves, it is particularly elegant, but also corrosion-resistant, the color is also very elegant, and it will not change for a long time , so it can be used to make precious specimens for long-term preservation.

[0027] Using this electroplating principle, it is also possible to electroplate non-metallic items such as flower...

Abstract

The invention provides a plating method for flowers and leaves comprising the steps of, cleaning with water to remove dirt in the gas cavity, immersing the pretreated flowers and leaves into solution containing tin chloride 8-12 g/l and chlorhydric acid 8-12 ml/l, for chemical plating, cleaning with water, immersing into water solution containing palladium chloride 0.15-0.25 g/l and chlorhydric acid 2-3 ml/l for surface activating treatment, then placing into solution containing nickel sulfate 25-0.25 g/l, sodium citrate 25-35 g/l, and ammonium chloride 45-55/l, regulating pH to 10-11 of chemical nickel plating solution through ammonia for chemical plating of nickel, rhodium and other noble metal to obtain the final ornament.

Description

technical field [0001] The present invention relates to a plant electroplating method, more precisely the present invention relates to an electroplating method for flowers and leaves. Background technique [0002] Electroplating generally refers to the electroplating of metal products, while the electroplating of non-metal products is a new process developed with the wide application of non-metal materials (especially plastics) in recent years. Bamboo, wood, flowers, plastics and other non-metals are all poor conductors of electricity and heat. Only when a layer of metal film is formed on the surface of the poor conductor can it be placed in the electroplating solution for electroplating. Therefore, how to pre-plating before electroplating A layer of good conductors is formed on the surface of flowers and leaves, and as the underlying metal, there is currently no better pretreatment method.
