Abstract

The invention belongs to building glass material, automobile using glass material and light fitting glass technique field. The coated glass with dual function of ultraviolet ray cutting off and infrared ray reflecting is includes substrate glass. Its features are that the substrate glass is coated infrared ray reflecting film and ultraviolet ray cutting off film. The ultraviolet ray cutting off film is titanium oxide- cerium oxide film, and both of their mass ratios are from ten percent to ninety percent. The infrared ray reflecting film is transparent bandwidth gap semiconductor oxide film, and it is one of the three as the following In2O3: Sn film, SnO2: Sb film, ZnO: AL film. And their mass ratios respectively are from 50.0percent to 99.0 percent to from 1.0 percent to 50.0 percent, from 80.0 percent to 99.9 percent to from 0.1 percent to 20.0 percent, and from 85.0 percent to 99.9 percent to from 0.1 percent to 15.0 percent. The invention that the cut-off ratio of the ultraviolet ray of is high, not influences the visible light transmittance, and has the function of saving energy. Its preparation method is simple.

Description

technical field [0001] The invention belongs to the technical field of architectural glass materials, automotive glass materials and lighting lamp glass, and in particular relates to a glass with a double-functional film layer for cutting ultraviolet rays and reflecting infrared rays coated on a glass substrate by a magnetron sputtering method and a preparation method thereof. Background technique [0002] Ultraviolet rays will age high molecular organic matter. In some special occasions, it is necessary to prevent ultraviolet rays from entering or exiting the glass. Substances in living rooms, museums, and cars, such as paper, fabrics, and some precious cultural relics, will age and deteriorate under ultraviolet radiation. [0003] At present, the method of preparing UV-blocking glass is to add cerium ions, Ce +3 Acting as a strong hole-trapping center, Ce +4 It plays a strong role in capturing electrons, so that the electrons and holes generated by the irradiation are c...
