Problems solved by technology

[0005] At present, the production of high-strength glass at home and abroad is mainly through the improvement of Al in glass. 2 o 3 content, however with Al 2 o 3 As the content increases, the viscosity of the glass increases, the clarification effect decreases, the number of bubbles in the glass increases, the volume increases, the melting effect of the glass becomes worse, and the hardening speed becomes faster, and it is easy to produce ribs and streaks on the surface of the glass , while increasing the annealing difficulty of the glass
In general, with the Al in the glass 2 o 3 As the content increases, the mechanical properties and optical properties of the glass will decrease, and the processing difficulty will increase

Description

technical field [0001] The invention relates to the technical field of glass manufacturing, in particular to a glass substrate and a preparation method thereof. Background technique [0002] With the continuous improvement of living standards, people's requirements for the surrounding environment are also getting higher and higher. The interior and exterior decoration of buildings must not only be safe and energy-saving, but also beautiful. Hard high-strength thick glass or hard high-strength colored glaze thick glass and its composite products (such as colored glaze laminated glass, etc.) can meet the above requirements. At the same time, because the glazed glass can not only realize various patterns through silk screen, but also realize different colors through pigment blending, and give dynamic beauty with the change of light, which provides inspiration and support for architectural designers. Therefore, glazed glass is widely used in the architectural decoration industr...
