Alkali aluminosilicate flexible glass suitable for ultraviolet laser processing

Abstract

The invention discloses alkali aluminosilicate flexible glass suitable for ultraviolet laser processing and belongs to the technical field of flexible glass. The alkali aluminosilicate flexible glassis prepared from 3.0 to 5.0 percent of an ultraviolet ultraviolet absorbent composition and 95.0 to 97.0 percent of oxide of an alkali aluminosilicate glass batch, wherein the ultraviolet absorbent composition comprises ferric oxide, molybdenum oxide, erbium oxide and potassium nitrate, and the ratio of ferric oxide to molybdenum oxide to erbium oxide to potassium nitrate in parts by weight is (1-3): (10-20): (4-8): (70-80); the oxide of the alkali aluminosilicate glass batch comprises the following, by weight, 54.0%-69.0% of silicon oxide, 5.0%-24.0% of aluminum oxide, 13.5%-18.0% of monovalent oxide and 4%-6% of divalent oxide, wherein the monovalent oxide is prepared from 0 to 3.5 percent of lithium oxide, 13.5 to 16.0 percent of sodium oxide and 0 to 3.5 percent of potassium oxide; andthe divalent oxide comprises 0-4.0% of calcium oxide, 3.0-6.0% of magnesium oxide and 0-3.0% of zinc oxide. According to the invention, high ultraviolet absorption and high visible light transmissionare realized, and a foundation is laid for application of the flexible glass in folding mobile phones and flexible photovoltaic products.

Description

technical field [0001] The invention belongs to the technical field of flexible glass, and relates to alkali aluminosilicate flexible glass, in particular to alkali aluminosilicate flexible glass suitable for ultraviolet laser processing. Background technique [0002] With the development of electronic information display products in the direction of thinner, larger, flexible, high-resolution, and high-contrast, under the traction of demand, electronic glass also develops in the direction of thinner, larger, and flexible. When the glass thickness reaches 0.1 When it is below mm (100μm), the glass will show excellent flexibility, so flexible glass was born. [0003] Flexible glass will change the way of flat glass storage and storage, which can meet the bending and winding method, and will realize roll-to-roll process technology in terms of processing and use. Technological workers have proposed many application scenarios for flexible glass, including flexible displays, flex...
