Vacuum silver coated glass and preparation process thereof

Abstract

The invention belongs to the technical field of vacuum coating products, and in particular relates to vacuum silver coated glass and a preparation process thereof. The vacuum silver coated glass comprises a glass substrate, a first reflective film layer, a second reflective film layer, a first protection film layer and a second protection film layer, the first reflective film layer, the second reflective film layer, the first protection film layer and the second protection film layer are successively placed on the glass substrate, the first reflective film layer is a pure silver layer, the second reflective film layer is a pure aluminum layer, the first protection film layer is a pure titanium layer, and the second protection film layer is a titanium oxide layer. The vacuum silver coated glass has high reflectivity and coating physical properties, more soft and bright gloss, better appearance effect, high surface hardness, and good water resistance and weather resistance.

Description

Technical field [0001] The invention belongs to the technical field of vacuum coating products, and particularly relates to a vacuum silver coating glass and a preparation process thereof. Background technique [0002] In the prior art, in terms of glass silver plating, the earliest water plating method was used, but the water plating method has been eliminated due to serious pollution. The current common processes include evaporative silver plating and magnetron sputtering silver plating, but evaporative silver plating and Magnetron sputtering silver plating has the following shortcomings: [0003] First, the application of evaporative silver plating is mainly to evaporate aluminum film or silver film, and then spray paint on the outer surface of the silver film as a protective layer. This process needs to be dried and cured by the coating and spray paint process, and the process turnover is large and easy to produce Uneven coating, poor film adhesion, etc., seriously affect the ...

AI Technical Summary

Problems solved by technology

[0003] First, the application of evaporative silver plating is mainly to evaporate and plate aluminum or silver films, and then spray paint on the outer surface of the silver film as a protective layer. Problems such as uneven coating and poor adhesion of the film layer seriously affect the quality of the coating and the low reflectivity;

[0004] Second, magnetron sputtering coating can be coated with many materials, such as aluminum, silver, chromium, titanium, etc., due to the limitation of the material itself, high reflectivity can be obtained when plating aluminum and silver, but the film layer It is easy to oxidize and requires a protective coating, while chrome plating and titanium plating have general anti-oxidation and water vapor resistance and low reflectivity
