Green series titanium alloy micro-arc oxidation coloring solution and preparation method thereof

The invention belongs to the field of metal coloring and dyeing in a surface treatment technology, and in particular, relates to a green series titanium alloy micro-arc oxidation coloring solution and a preparation method thereof, used for solving the defects of an electrolytic colored film. The coloring solution comprises a micro-arc oxidation spark discharge introducing agent for producing micro-arc oxidation, a green micro-arc oxidation coloring agent, a green film compactness accelerant, a green micro-arc oxidation film color homogenizing agent, a green film stabilizer and a bath solution stabilizer. By using the solution for micro-arc oxidation coloring, the thickness of the film can reach 22 microns, the film is green as required when the thickness is 3 to 22 microns, and the formed film is stable in color, has the characteristics of touch resistance and abrasion resistance, is compact and does not adsorb dirt. More preferably, the film does not contain organic substances, and can tolerate ultraviolet f
