Abstract
The invention discloses decorative nickel-copper-gold ternary alloy electroplating liquid. The electroplating liquid comprises 30-60 g/L of nickel sulfate, 20-60 g/L of copper sulfate, 8-15 g/L of chloroauric acid, 5-15 g/L of citric acid, 2-3 g/L of sodium dodecyl sulfate, 20-40 g/L of sodium sulfate and 0.2-0.5 g/L of N-(3-sulfopropyl) pyridinium hydroxide inner salt, and the pH value is adjusted to be 8-10 through ammonia water. The decorative nickel-copper-gold ternary alloy electroplating liquid is easy to manufacture, non-poisonous, environmentally friendly, uniform in dispersibility and good in stability and can be used within a wide current range; a coating obtained by electroplating is uniform and bright and has high abrasion resistance and hardness.
Description
Technical field
The present invention relates to technical field of nanometer material preparation, be specifically related to a kind of ornamental ambrose alloy gold ternary alloys plating liquid.
Background technology
Commonly use in coinage field the decorative coating materials that electroplated coinage made by gunmetal, current electricity Du Tong ?tin alloy technology mainly adopt containing cyanogen plating or plate respectively after monometallic and adopt heat-treating methods to form alloy layer, harm environment or technique loaded down with trivial details.Ambrose alloy gold ternary alloy has flavous outward appearance, but also can carry out chemical stain in its surface, to reach special decorative effect, therefore, is widely used in decorative coating.Simultaneously ambrose alloy gold ternary alloy has high-wearing feature and high rigidity, therefore, alternative Tong ?tin binary alloy as the decorative coating materials of coinage.The report that current ambrose alloy gold ternary alloys plating liquid is used for coinage is less.
The performance of electroplate liquid is the important factor affecting coating, pursue a kind of form simple, use the direction that current density is wide, electroplate liquid that is easy care is people's effort always.
Summary of the invention
Goal of the invention: for the deficiencies in the prior art, the invention provides a kind of ornamental ambrose alloy gold ternary alloys plating liquid, make this electroplate liquid prepare simple, good stability, asepsis environment-protecting, electroplating efficiency are high.
Technical scheme: for achieving the above object, the present invention by the following technical solutions:
A kind of ornamental ambrose alloy gold ternary alloys plating liquid, comprise following component: single nickel salt 30-60g/L, copper sulfate 20-60g/L, hydrochloro-auric acid 8-15g/L, citric acid 5-15g/L, sodium laurylsulfonate 2-3g/L, sodium sulfate 20-40g/L, N-(3-sulfopropyl) pyridinium inner salt 0.2-0.5g/L, and be 8-10 by ammoniacal liquor adjust ph.
Further, 3-(3-pyridyl)-vinylformic acid 1-5g/L is also comprised in electroplate liquid.
Further, the temperature of electroplate liquid controls at 10-70 DEG C.
Preferably, a kind of ornamental ambrose alloy gold ternary alloys plating liquid, comprise following component: single nickel salt 30g/L, copper sulfate 30g/L, hydrochloro-auric acid 8g/L, citric acid 15g/L, sodium laurylsulfonate 3g/L, sodium sulfate 40g/L, N-(3-sulfopropyl) pyridinium inner salt 0.2-0.5g/L, 3-(3-pyridyl)-vinylformic acid 2-4g/L.
Beneficial effect: compared with prior art, plating solution provided by the invention not only makes simply, asepsis environment-protecting, dispersed even, good stability, and can use in wider range of current, electroplates the coating obtained evenly bright, has high-wearing feature and high rigidity.
