Abstract

The invention discloses a high-efficiency environment-friendly nickel stripper and a preparation method thereof, which solve the problems of low stripping speed and high stripping temperature of a nickel layer and hostile operating environment. Based on 100 parts by weight, the high-efficiency environment-friendly nickel stripper comprises the following substances: 5.19 to 12.82 parts of ethanediamine, 5.19 to 12.82 parts of sodium metanitrobenzene sulfonate, 0.74 to 1.71 parts of citric acid, 1.48 to 2.56 parts of an organic amine additive and 70.09 to 87.40 parts of pure water. The invention also discloses the preparation method of the high-efficiency environment-friendly nickel stripper. According to the high-efficiency environment-friendly nickel stripper and the preparation method thereof, quick stripping of the nickel layer is promoted; in particular, after the organic amine additive is used, the stripping speed of the nickel layer is greatly increased, the stripping temperature is reduced, and a great deal of smoke generated during stripping is reduced.

Description

technical field [0001] The invention relates to a nickel stripping agent and a preparation method of the nickel stripping agent. Background technique [0002] With the rapid development of modern science and technology and industrial construction, electroplating nickel and its alloys have been widely used as a technology in aviation, aerospace, machinery, automobiles, molds, electronics, computers, food, medical and other fields, and electroplating nickel Output has gradually become one of the important indicators to measure the level of a country's electroplating technology. However, some unqualified products will inevitably be produced during the nickel plating process, such as partial failure of the nickel layer; poor corrosion resistance; for workpieces with strict tolerance dimensions, the thickness of the nickel plating cannot meet the requirements; needles appear on the surface of the nickel layer. Holes, spots, peeling, blistering and other defects. If these unqu...
