Problems solved by technology

[0003] The main coatings used in the prior art include hexavalent chromium, copper-tin alloy, silver, gold, etc., but the sewage generated by the electroplating hexavalent chromium process is difficult to handle, which seriously pollutes the environment and the coating is not environmentally friendly; the copper-tin coating can only withstand 80~ 100°C, if the temperature exceeds this temperature, the coating will turn black and blue, and cannot maintain the silvery white color; the most commonly used silver plating solution in the silver plating process is the silver plating solution containing cyanide, because cyanide is a strong Toxic substances, this silver plating solution containing cyanide will greatly endanger the health of the silver plating process workers; although the gold plating process can improve the conductive contact resistance and enhance signal transmission, but its cost is high

Abstract

The invention discloses an electroplating solution for the surface of a metal tool and an electroplating process, and belongs to the technical field of metal material processing. The electroplating solution is prepared from 18-35g / L of soluble trivalent chromium salt, 15-22g / L of soluble zinc salt, 80-150mL / L of complexing agent, 15-26mL / L of buffering agent, 3- mL / L of brightening agent and the balance deionized water; the complexing agent is prepared from, by mass, 1.2-10% of antimony potassium tartrate, 2-8% of dithioglycol, 25-35% of amine derivative and the balance deionized water; and the brightening agent is prepared from, by mass, 1-2% of polyethylene glycol, 15-20% of sulfonate, 2-3% of benzalacetone and the balance deionized water. The electroplating solution can effectively improve the surface performance of the metal tool, enhance the surface hardness and improve the wear resistance and corrosion resistance of the metal tool.

Description

technical field [0001] The invention belongs to the technical field of metal material processing, and in particular relates to an electroplating solution and an electroplating process for the surface of a metal tool. Background technique [0002] Electroplating is the process of plating a thin layer of other metals or alloys on the surface of certain metals using the principle of electrolysis. It is a process of using electrolysis to attach a layer of metal film to the surface of metal or other material parts to prevent metal oxidation ( Such as rust), improve wear resistance, electrical conductivity, reflectivity, corrosion resistance and enhance the appearance. [0003] The main coatings used in the prior art include hexavalent chromium, copper-tin alloy, silver, gold, etc., but the sewage generated by the electroplating hexavalent chromium process is difficult to handle, which seriously pollutes the environment and the coating is not environmentally friendly; the copper...
