Abstract
The invention provides a silver mirror which has clear images and is not easy to fall. The silver mirror is characterized in that the surface of a glass substrate is sequentially provided with a silver layer, a copper layer, a mirror primer and a mirror topcoat; the thickness of the silver layer is 700-800mg/m[2]; and the thickness of the copper layer is 180-220mg/m[2]. The production method of the silver mirror comprises the following steps of: 1) polishing the surface of the glass substrate by polishing powder of CeO2 with the weight percentage of 70-75%, washing the surface by deioned waterand subsequently spraying an active agent; keeping the surface still for a while and washing the surface by the deioned water again; 2) coating the silver layer and the copper layer on the surface of the glass substrate and respectively forming the silver layer and the copper layer with the thickness of 700-800mg/m[2] and 180-220mg/m[2]; 3) washing the surface by the deioned water and drying thesurface; and 4) spraying the mirror primer and the mirror topcoat. The invention uses the polishing powder with high CeO2 content to polish the surface of the glass substrate, has strong cleaning capability, leads the silver layer not easy to fall, and has clearer silver mirror and longer service life by controlling the thickness of the silver layer and the copper layer.
