Abstract

The invention discloses a copper ornament brightening agent and a preparation method thereof and relates to the technical field of chemical agents. The copper ornament brightening agent is characterized by comprising the following raw materials including, by weight, 4-6 parts of benzalacetone, 4-6 parts of p-chlorobenzalacetone, 30-35 parts of polyethylene glycol, 7-9 parts of sodium benzoate, 2-5 parts of NNO and 50-60 parts of distilled water. The preparation method comprises the following steps that A, the distilled water and the benzalacetone are added into a reaction vessel; B, the p-chlorobenzalacetone is added into the reaction vessel; C, the polyethylene glycol is slowly added into the reaction vessel; and D, the sodium benzoate and the NNO are added into the reaction vessel. Compared with the prior art, the problems that when an existing copper ornament brightening agent carries out chemical polishing treatment on the surfaces of copper ornaments, toxic substances are easily generated and environment is polluted can be solved.

Description

technical field [0001] The invention relates to the technical field of chemical preparations, in particular to a brightener for copper ornaments and a preparation method thereof. Background technique [0002] Copper ornaments need to be surface polished before electroplating to prevent the finished copper ornaments from being easily oxidized and vulcanized after plating; the commonly used polishing treatment method is chemical polishing, that is, the ornaments are immersed in a solution containing a brightener. It is leveled by the solution to obtain a bright surface; although the existing brightener can achieve the effect of leveling the surface of the jewelry and removing impurities, it is easy to volatilize toxic substances during the treatment process, and the waste water generated after the treatment is also difficult to deal with. Can not meet environmental protection requirements. Contents of the invention [0003] The object of the present invention is to provide ...
