Abstract

The invention belongs to the technical field of additives for electroplating, and specifically discloses a brightener for VCP electroplating and a preparation method thereof. The brightener for VCP electroplating contains a leveling agent, polyepichlorohydrin, a curing Agent, citric acid, boric acid and a chelating agent, wherein an oxidizing agent on the surface of a plating can be effectively removed through mixing of weak acid substances, namely the citric acid and the boric acid; the dirt on the surface of the plating can be effectively removed through addition of the polyepichlorohydrin,not counting the plating; other components are added, so that the formula components are reasonable and effective, the preparation process is free of pollution, environment-friendly and safe; the brightener is good in brightness, not prone to oxidization, convenient to use, good in electroplating quality, high in plating brightness, stable, durable and non-discolored, wide in popularization and application values and good in economic and social benefits.

Description

Technical field [0001] The invention belongs to the technical field of additives for electroplating, and particularly relates to a brightener for VCP electroplating and a preparation method thereof. Background technique [0002] In the industrial industry, such as plastics, optical glass lenses, metal products (copper, iron, aluminum, steel, zinc, alloy) and other materials to clean the surface drawing oil, cutting oil, anti-rust oil, lubricating oil, stamping oil, etc. When planting oil, stains, and grease, it is often necessary to clean, and most of them use diesel, kerosene or gasoline as cleaning fluid to clean the parts. This not only wastes energy, but also has potential unsafe factors. A little carelessness may cause a fire. In addition, the used cleaning agent itself has great defects, the quality is different, the overall decontamination performance is poor, it is easy to cause corrosion hazards to the human body, the safety is low, and the surface color after decontami...
