[0004] The patent application with the application publication number CN105967517, the application name is a formula and preparation process of high-strength flat glass, and the application number is 201610300949.2, which discloses a formula of high-strength flat glass. Although the prepared glass has high strength, the glass Poor tensile strength, easily shatters under impact, and costs more
[0005] The methods for strengthening the strength of flat glass in the prior art all require secondary reprocessing of the original glass sheet, which not only requires complex processes and equipment, but also requires a large amount of new manpower, material and financial resources, and high energy consumption. Reinforced glass is also not ideal

Description

technical field [0001] The invention belongs to the technical field of flat glass preparation, and in particular relates to a preparation method of nano-ceramic modified high-strength flat glass. Background technique [0002] Flat glass is also called white glass or clear glass. It has the properties of light transmission, transparency, heat preservation, sound insulation, wear resistance and climate change resistance. The theoretical strength of ordinary flat glass is very high, but the actual strength is low, which is 2 to 3 orders of magnitude lower than the theoretical strength. Flat glass can be divided into thin glass, thick glass, and extra-thick glass according to thickness; it can be divided into ordinary flat glass, embossed glass, polished glass, float glass, etc. according to surface state. Flat glass can also be made into products with different colors and various special properties through coloring, surface treatment, compounding and other processes, such a...
