Abstract
The present invention relates to a novel dark brown decorative mirror and a chemically plating method thereof. The method relates to the surface treatment of glass. The decorative mirror is composed of a colorless transparent glass base sheet, a reflecting copper plating layer, protecting paint and protecting surface paint. The color of a mirror surface is dark brown or bronze, and the visual light reflectivity of the mirror surface is 86 to 90% of that of a silver plating mirror. The method adopts a showering and coating mode to sensitize and activate the mirror surface, and the chemical copper plating layer is used as a reflecting layer. The mirror made by the method can be used as indoor wall surfaces, cylindrical surfaces and ceilings and can be used for the decoration of outdoor storefronts.
Description
The present invention relates to a kind of surface treatment of glass, particularly relate to dark brown decorative mirror and the chemically plating method thereof made in the surface chemistry of colourless transparent glass substrate.
Development along with construction industry, dark brown decorative mirror is as decorateing the decoration that has been widely used in indoor wall, cylinder, top ceiling and the outdoor shop front in places such as hotel, hotel, market, dance hall with the subject type of mirror, it gives the atmosphere of environment uniqueness, gives beautiful feeling.Mostly existing dark brown decorative mirror (commercially available) technology of preparing is that with the high-quality cranberry glass be substrate, and adopting with aluminium is the vacuum aluminum-coated membrane method single face plating reflective aluminum of evaporating materials, coats protective paint then and makes.This method shortcoming: (1) needs large-scale special-purpose vacuum coater and the production environment of having relatively high expectations.Investment is big, requires high.(2) be subjected to the restriction of vacuum plating container, prepare comparatively difficulty of large-size glass mirror.(3) the system mirror is bigger to the distortion effect of mirror with the planeness of glass, and therefore domestic mirror manufacturer mainly selects for use the import cranberry glass to make substrate, so that substrate cost height.(4) on the cranberry glass substrate the vacuum aluminum-coated mirror of making be subjected to the specularly reflected rate that influences of the tone of glass own generally lower (for silvered mirror 40～60%), give gloomy, colder sensation, decorative effect is not good.The Chinese utility model patent that on January 12nd, 8 or seven submitted to, 85200121 of application numbers are called the scheme that " civil mirror of replacing silver with copper " proposed preparation Sandy glass on colourless transparent glass, but do not see its concrete case study on implementation, do not see this products production and application on the market yet.
The purpose of this invention is to provide a kind of novel dark brown decorative mirror, and be provided at the chemical method of making novel dark brown decorative mirror on colourless transparent glass (dull and stereotyped float glass, the system mirror sheet glass) substrate.This method mainly comprises following four steps: the sensitization and the activation treatment of (1) glass substrate: promptly glass substrate carries out pre-treatment (containing 5～10 grammes per square metre potassiumchromates in per 100 parts of sulphuric acid solns) with commercially available scrubbing powder and the sulphuric acid soln that contains 5～10 weight % potassium bichromate.Removing the organic and inorganic dirt settling of glass surface, showering tindichloride (SnCl is then distinguished in the one side of glass substrate in preheating substrate to 25～35 ℃

2O) 0.01～10 weight % sensitizing solution and Silver Nitrate (AgNO
3) 0.5～2 grams per liter activation solution.(2) electroless plating: the glass substrate that has activated flooded in the normal temperature chemical copper plating solution 8～15 minutes, thereby had simultaneously formed a reflective copper layer that combination is good at glass substrate activatory.The chemical copper plating solution component is as follows:

(3) drying: the glass substrate behind the chemically plating is 60 ℃ of dryings under atmospheric environment.
(4) brushing protective paint:, protected at brushing primer of reflective copper coating and finish paint as usual for the fresh reflective copper layer oxidation stain after preventing to be coated with influences specular reflectance.
Effect of the present invention is as follows:
Its advantage of novel dark brown decorative mirror made from method provided by the invention is: one, beautiful in colour with the vacuum aluminum-coated dark brown mirror that makes of cranberry glass, the visible reflectance height is (with the silvered mirror visible reflectance of five mm thick as 100%, the depth that the vacuum aluminum-coated dark brown mirror of same thickness is looked the tone of glass substrate own is 40～60% of a silvered mirror, and with five millimeters novel dark brown decorative mirrors that the present invention makes be silvered mirror 85%).And give splendid beautiful feeling.Two, because the present invention's chemically plating on the colourless transparent glass substrate, thereby cost is low, it does not need special-purpose vacuum coater, only need to deposit chemical solution and get final product with the polyvinyl chloride plastic hopper that is coated with the similar size of mirror size, so facility investment is also few, and system mirror size is unrestricted.
