Abstract
Silver plating reflector glass for solar thermal power generation and a preparation method of the same. A surface of glass is plated with a silver film layer through a chemical reaction, thereby greatly improving reflectivity of the glass, and the reflectivity can reach over 95%. The sequence of steps of the preparation method is as follows: cleaning, polishing, sensibilization and activating treatment are performed on a glass substrate; a silver nitrate ammonia solution and a reducing agent are sprayed on a surface of glass at the same time, and through a redox reaction of 2 to 3 minutes, silver ions in the silver nitrate ammonia solution is reduced to metallic silver which is precipitated on the surface of the glass, thereby forming a silver film layer reflecting film; the silver film layer is passivated; the silver film layer is plated with a copper film layer; a primer layer is sprayed on the copper film layer; a finish layer is sprayed on the primer layer; and reflector glass is obtained by cleaning.
