![]() ![]() The blackening solution has the advantages of short blackening time, abrasion-resistant blackening films, pure black, low production cost and the like and has wide popularization and application prospects. By the brass part blackening solution, the problems that the conventional copper ammoxidation blackening solution is unstable, ammonia water is highly volatile to cause environment pollution, the blackening films are loose and not firm or abrasion-resistant and has impure colors and the like are solved and by the preparation method, the blackening solution which can quickly blacken atnormal temperature is prepared. ![]() The preparation method comprises the following steps of: preparing the blackening solution, etching solution and activating solution etching degreased brass parts activating putting the activated brass parts into the blackening solution for blackening taking the brass parts out, cleaning with distilled water, and drying closing in paint oil and air drying to obtain the blackened brass parts. ![]() The invention discloses a brass part blackening solution and a preparation method and application thereof, relates to a process for treating the surface of a brass part and provides brass part blackening solution which is stable in blackening, has short blackening time and low cost and makes blackening films abrasion-resistant, pure black and highly bright, and a preparation method and application thereof.
