A TRANSPARENT COATINGS FOR COPPER SURFACE PROTECTION
铜表面透明防蚀封护剂的研究

Protective coatings for copper alloy were prepared using acrylic resin emulsion modified by nanometer TiO_2 and corrosion inhibitor Benzotriazole(BTA).Electrochemical impendance spectroscopy(EIS),ultraviolet spectroscopy,salt fog test,chemical resistance,water proofness and mechanical performances were all employed to study its properties.Results showed that the coatings have excellent performances and can protect copper alloy effectively.Anti-ultraviolet aging ability of coatings is improved effectively by adding nanometer TiO_2.The coating is achromic,transparent,non-toxic and odorless.It's friendly to environment.
