Abstract

The invention relates to a glass coat at the glass base plate and with function of cutting off the ultraviolet ray and its preparation method. The ultraviolet ray cutting off coated glass includes substrate glass. Its features are that the substrate glass is coated titanium oxide- cerium oxide film. The features of its preparation method include the following that the first is cleaning and drying the coated glass substrate glass, after this, doing fore-vacuum transition; the second is adopting the magnetron sputtering coating method to coat film; a: preparing target material, the target material is made up of titanium oxide and titanium oxide, and both of their mass percent in each constituent are from ten percent to ninety percent; b: the substrate glass is dong magnetron sputtering coating in the pure argon gas or oxygen argon mixture, the range of sputtering air pressure is from 0.10Pa to 3.0Pa. Its cut- off ratio is high, and not influences the visible light transmittance. Its preparation method is simple.

Description

technical field [0001] The invention belongs to the technical fields of architectural glass materials, automotive glass materials and lighting fixture glass, and in particular relates to a glass plated with an ultraviolet cutoff function film layer on a glass substrate and a preparation method thereof. Background technique [0002] Ultraviolet rays will age polymer organic matter, and in some special occasions, it is necessary to prevent ultraviolet rays from entering or exiting glass. For example, organic resins are used in the components of solar cells, especially solar cells on aircraft in aviation and spaceflight activities, and the conversion efficiency will be reduced due to ultraviolet radiation. Especially in space, where the intensity of ultraviolet light is about 20 times that of the earth's surface. Substances in living rooms, museums, and cars, such as paper, fabrics, and some precious cultural relics, will age and deteriorate under ultraviolet radiation. [00...
