Vacuum silver coated glass and preparation process thereof

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.
