Abstract

The invention discloses a coated glass with the double functions of visible light reducing reflection and ultraviolet radiation cutting-off and the preparation method thereof. A film layer structure of the coated glass is glass uropatagia/ titanium oxide- cerium oxide film/silicon dioxide layer with a plurality of holes, or silicon dioxide layer with a plurality of holes/titanium oxide- cerium oxide film/glass uropatagia/titanium oxide- cerium oxide film/silicon dioxide layer with a plurality of holes. The transmittivity of the visible light is 92 to 98 percent, the ultraviolet radiation cutting-off is larger than or equal to 96 percent. The thickness of the titanium oxide- cerium oxide film layer is 10 to 500nm, the components have the mass ratio that the titanium oxide is 10 to 90 percent, and the cerium oxide is 10 to 90 percent; the thickness of the silicon dioxide layer with a plurality of holes is 20 to 200nm, and the volume of the holes is 10 to 80 percent. The coated glass adopts the preparation method of a single-side spraying process or a double-side dipping and pulling method. Feed liquid for preparing the titanium oxide and the cerium oxide film layer comprises organotitanium and dissolubility cerous salt; the feed liquid for preparing the silicon dioxide layer with a plurality of holes comprises silicon ester, water, and ethanol, and ammonia is used as activator, wherein, the quality of silicon is 1 to 5 percent. The coated glass is performed with the heat treatment under the temperature of 400 to 550 Deg C. The invention can be used as the glass of an autocar, a train, a steamship, buildings and a spotlight.

Description

technical field [0001] The invention belongs to the technical field of glass materials for automobiles, trains, ships, buildings and lighting lamps, and specifically relates to a coated glass coated on a glass substrate and having a dual-functional composite film layer of visible light anti-reflection / ultraviolet cut-off 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. Substances in living rooms, museums, automobiles, ships and trains, such as paper, fabrics, plastic products and some precious cultural relics, will age and deteriorate under the irradiation of ultraviolet rays. At present, there are two methods for preparing UV-cut glass. The first method is to add cerium ions to the raw material components during glass production. The amount of UV cut-off is related to the thickness of the glass and the ...
