Abstract

The invention belongs to the technical field of flexible glass, and provides alkali aluminosilicate flexible glass with ultraviolet absorption and low surface tension, which is prepared from the following components in percentage by mass: 3 to 5 percent of a glass melt active substance composition, 3 to 5 percent of an ultraviolet absorbent composition and 90 to 94 percent of an alkali aluminosilicate glass batch, wherein the glass melt active substance composition is prepared from the following components in parts by mass: 1 to 2 parts of niobium pentoxide, 20 to 30 parts of antimonous oxideand 35 to 40 parts of potassium nitrate; the ultraviolet absorbent composition comprises 1-3 parts of ferric oxide, 10-20 parts of molybdenum trioxide, 4-8 parts of erbium oxide and 35-40 parts of potassium nitrate. By means of the technical scheme, the problem that in the prior art, surface tension of glass melt is large, forming of flexible glass is not facilitated, and picosecond ultraviolet laser machining quality is not high is solved.

Description

technical field [0001] The invention belongs to the technical field of flexible glass, and relates to an alkali-aluminosilicate flexible glass with ultraviolet absorption and low surface tension. Background technique [0002] With the development of electronic information display products in the direction of thinner, larger, flexible, high-resolution, high-contrast, etc., under the traction of demand, electronic glass also develops in the direction of thinner, larger, and more flexible. When the glass thickness reaches When it is less than 0.1mm (100μm), the glass will show excellent flexibility, so flexible glass varieties are born. [0003] Flexible glass will change the way of flat glass storage and storage, which can meet bending and winding, 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, flexible photovoltaic products, wearab...
