Problems solved by technology

[0008] From the research and development of ultra-thin glass above, it can be seen that both domestic and foreign countries have made great progress in the process of manufacturing ultra-thin glass, but with the development of science and technology and the increase of people's living needs, the demand for ultra-thin glass will continue to grow The performance requirements for ultra-thin glass will also be higher and higher, but the traditional methods of preparing ultra-thin glass have different shortcomings, such as point defects in the preparation of float glass affected by the molding environment, Thickness difference, microscopic waviness and warpage, etc., directly affect the processing and end-use performance of the product, so no matter the defects inside the glass or the glass appearance, further measures need to be taken to improve

Abstract

The invention discloses a method for preparing flexible ultra-thin glass. Using chemical vapor deposition technology, firstly prepare a layer of silicon nitride film on a tin solution with a low melting point, then prepare a layer of silicon dioxide film, and finally extract Si 3 N 4 / SiO 2 Film, according to the use of flexible glass for the corresponding polishing treatment. The invention also discloses a preparation method of the flexible ultra-thin glass, which adopts the fusing technology of broken glass powder. The preparation method of the two kinds of flexible ultra-thin glasses of the present invention is simple, the source of production raw materials is abundant, and the price is cheap, and the flexible ultra-thin glass with a thickness of 1 μm to 50 μm can be obtained, and the obtained ultra-thin glass has high flexibility and good light transmittance. The flexible ultra-thin glass obtained by the invention has extremely strong application potential and can be widely used in the field of TFT-LCD liquid crystal display and new energy fields such as thin film solar cells.

Description

technical field [0001] The invention relates to the field of production and processing of ultra-thin glass, in particular to a method for preparing flexible ultra-thin glass used in the fields of microelectronic components and thin-film solar cells. Background technique [0002] Ordinary glass is generally made of quartz sand, soda ash, feldspar and limestone at high temperature. During the cooling process, the viscosity of the melt gradually increases and brittle and transparent solid materials without crystallization can be obtained, such as: quartz glass, silicate glass, soda lime glass, fluoride glass, etc. Among them, silicate glass is obtained by using quartz sand, soda ash, feldspar and limestone as raw materials, after mixing, high-temperature melting, homogenization, processing and forming, and then annealing, it is widely used in construction, daily use, medical treatment, chemistry, etc. , electronics, instrumentation, nuclear engineering and other fields.
