Abstract

The invention aims to provide ultraviolet complete-cutoff coated glass prepared by a magnetron sputtering method, and a preparation method thereof, which comprise ultraviolet complete-cutoff sunshine-control coated glass or ultraviolet complete-cutoff sunshine-control low-radiation coated glass and preparation methods thereof. A glass substrate is coated with a silicon or silicon alloy film serving as an ultraviolet absorption film, and the characteristic that the cutoff wavelength of the silicon or silicon alloy film is between 400 and 550 nm is utilized to completely cut off ultraviolet rays. The thickness of the silicon or silicon alloy film is 10 to 200 nm; Ar is used as working gas; and the working pressure is 0.30 to 0.37 Pa. Pure silicon target material is used to sputter and deposit the silicon film, or silicon-alloy target material formed by adding B, P, Al, C and Ge to pure silicon is used to sputter and deposit the silicon alloy film. The coated glass has wide application in automobiles, trains, ships, buildings, glass material for household appliances and illuminating glass lamp industry with broad prospects.

Description

technical field [0001] The invention specifically relates to a completely cut-off ultraviolet coated glass and a preparation method thereof. It belongs to the technical field of glass for automobiles, trains, ships, buildings, home appliances and lighting lamps. 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. Substances in living rooms, museums, cars, ships, trains and home appliances, such as paper, fabrics, plastic products and some precious cultural relics, will age and deteriorate under ultraviolet radiation; A substance that can reach a position. At present, there are two ways to prepare UV-cut glass. The first method is to add cerium ions to the raw material components when producing glass. The amount of UV cut-off is related to the thickness of the glass and the amount of cerium doped. The problem of this preparation method is t...
