Preparation method of coated glass

Abstract

The invention provides a preparation method of coated glass. The preparation method of the coated glass comprises the following steps of: S1, providing a glass substrate; S2, sputtering and depositinga functional film layer on the glass substrate; and S3, sputtering and depositing a zirconium oxide abrasion-resistant layer on the side, different from the glass substrate, of the functional film layer, wherein the isolation coefficient of a sputtering cavity of the zirconium oxide abrasion-resistant layer and a sputtering cavity of the adjacent functional film layer is at least 30, the zirconium oxide abrasion-resistant layer adopts a medium-frequency power supply, and sputtering and depositing are controlled in a current mode. According to the preparation method of the coated glass, it canbe guaranteed that the zirconium oxide wear-resistant layer is stable in starting and uniform in film sputtering in the sputtering deposition process, and meanwhile the surface of the zirconium oxidetarget material is free of nodulation. On the other hand, the strength of a coated glass film layer obtained by the preparation method of the coated glass is obviously improved, the requirements of cold processing and heat treatment of glass deep processing can be met, and the preparation method is worth popularizing and using in the industry.

Description

technical field [0001] The invention relates to the technical field of architectural glass curtain walls, in particular to a preparation method of coated glass. Background technique [0002] At present, coated glass has been widely used in various fields due to its excellent performance. However, during its transportation and storage, the substrate film layer is easily scratched and worn, and its silver layer is easily oxidized. In addition, the physical and chemical properties of coated glass are easy to change after various cold processing and heat treatment, such as slicing, abrasion, interlayer and other treatments. [0003] In response to the above problems, most domestic glass deep-processing enterprises currently use PE organic film to protect the substrate film layer. Although it can play a certain protective role, when the substrate needs to be used, it needs to be manually peeled off, and the film layer cannot be reused. , and it is not easy to degrade, and the b...
