Gold-imitation coated glass and preparation technology thereof

Abstract

The invention belongs to the technical field of vacuum coating products, and particularly relates to gold-imitation coated glass and a preparation technology thereof. The gold-imitation coated glass comprises a glass substrate, and a hydrophilic ionized layer, a pure titanium film layer, a pure titanium and titanium nitride mixed film layer and a nitrogen-rich heat treatment layer which are sequentially arranged on the surface of the glass substrate. The gold-imitation coated glass has the relatively good surface glossiness, and a gold-imitation film layer is high in adhesive force, so that a relatively rich color selection effect can be provided, and the color repeatability is high; the gold-imitation coated glass has relatively high film layer binding force, a relatively compact surface effect, relatively high film layer wear resistance, acid corrosion resistance and the like, thus being widely applied to window glass such as a mobile phone panel and a computer touch screen.

Description

technical field [0001] The invention belongs to the technical field of vacuum coating products, in particular to a gold imitation coated glass and a preparation process thereof. Background technique [0002] In the prior art, regarding glass imitation gold coating, there are three common coating processes: (1) evaporation coating; (2) magnetron sputtering; (3) and ion sputtering coating process. [0003] Among them: first, regarding the evaporation coating, the evaporation coating process is mainly to coat a highly reflective silver film, and then spray a layer of coating on the outer surface of the silver film to imitate gold color. The main problem of this film layer is the film layer. Poor binding force, insufficient hardness, easy to break due to collision, and the whole film layer falls off, etc., so the application range is small and not suitable for wide application. [0004] Second, regarding the magnetron sputtering coating, the main problems of the magnetron sputt...

AI Technical Summary

Problems solved by technology

[0003] Among them: first, with regard to evaporation coating, the evaporation coating process is mainly to plate a highly reflective silver film, and then spray a layer of coating on the outer surface of the silver film to imitate gold color. The main problem of this film layer is the film layer. Poor binding force, insufficient hardness, easy to break due to collision, the entire film layer falls off, etc., so the application range is small, not suitable for wide application

[0004] Second, regarding the magnetron sputtering coating, the main problems of the magnetron sputtering coating are due to the low ionization rate of the process, the low content of titanium nitride in the film layer, or the narrow color range of the coating. Layer adhesion deviation, poor coating effect

[0005] Third, with regard to particle sputtering coating, ion sputtering film has high adhesion, high ionization rate, and good color effect, but the biggest problem is that the film has poor roughness, low gloss, and poor appearance.
