Abstract
The invention provides a copper-free silver mirror which has sharp image and is not easy to fall off, which comprises a glass substrate; wherein, silver layers, mirror primer and mirror finish are arranged on the surface of the glass substrate in sequence; the thickness of the silver layer is 900-1000mg/m2. The manufacturing method of the copper-free silver mirror comprises the following steps:1) using polishing powder containing 70%-75% of CeO2 by weight to polish the surface of the glass substrate, carrying out deionized water rinsing on the surface, spraying active agent, standing for aperiod of time and carrying out deionized water rinsing again; 2) spraying catalyst solution which consists of the following components by weight percentage: 28-30% of PdC2, 5%-6% of Ru, 1%-1.2% of HC1 and the rest of deionized water; 3) coating silver layer with thickness of 900-1000 mg/m2 and passivant on the surface of the glass substrate; 4) carrying out deionized water rinsing and then drying; 5) curtaining the mirror primer and mirror finish. The mirror is sprayed with catalyst containing PdCl2 and the passivant containing Snf2 are sprayed rather than cooper layer, therefore, the image is sharper and not easy to fall off.
Description
Technical field
The present invention relates to a kind of copper-free silver mirror and working method thereof.
Background technology
At present the working method of silver mirror is: adopt earlier cleanser and tap water to the glass baseplate surface clean with polishing after; The spray activating agent waits for a period of time and uses deionized water rinsing again, plates behind the silverskin copper plating film again; Treat that the stable back of copper layer is with the unnecessary impurity in deionized water rinsing glass baseplate surface; Plate priming paint after drying up glass surface with the dry-air blast machine,, can obtain the finished product mirror through simple cleaning after the oven dry with surfacing lacquer again after the baking box oven dry.The shortcoming of the silver mirror of producing with this method is: 1) since to the clean ability on glass baseplate surface a little less than, so the adhesion of itself and silver layer is relatively poor, comes off easily; 2) reflectivity of mirror is lower, the anti-abrasive resistance in reflection horizon a little less than.
