Abstract

The present invention relates to a glass composition, the composition is (wt%): SiO2 60~70, Al2O3 5~13, Na2O 6~12, K2O 1~3, Li2O 0~1, MgO 2~6, CaO 3 ~7.5, ZrO2 0~2. The glass material has excellent mechanical strength and optical properties without any post-treatment such as physical tempering, chemical tempering, acid etching, and fire throwing. It is suitable for architectural window glass, automobiles, high-speed trains, and airplanes. The windshield can effectively save energy and reduce production costs.

Description

technical field [0001] The present invention relates to a glass composition and a high-strength flat glass made from it, its manufacturing method and application. Specifically, the present invention relates to a glass composition which does not undergo physical tempering, chemical tempering, acid etching, etc. After treatment, it can be made into higher-strength flat glass and the method and application of preparing flat glass therefrom. Background technique [0002] With the rapid development of China's economy, high-rise buildings and transportation industries have been greatly developed, and the demand for flat glass in various industries has further increased. Currently, insulating glass, heat-reflecting glass, and heat-absorbing glass embossed glass are mainly used in windows, and laminated glass is mainly used in front glass of automobiles, high-speed trains and aircraft. These glasses are all based on ordinary soda-lime-silicon flat glass, but the hardness and mechan...
