Abstract

The invention discloses a composite performance reinforcing agent for producing alumina silicate glass. The composite performance reinforcing agent for producing alumina silicate glass is the combination of at least two of metal oxides, including K2SO4, Na2SO4, Li2SO4, KNO3, NaNO3, LiNO3, SnO2 and Sb2O3, and two of rear-earth oxides, including La2O3, CeO2, Sm2O3, Yb2O3 and Nd2O3; the composite performance reinforcing agent is added to the basic formula of the alumina silicate glass, on one hand, the clarification performance of the alumina silicate glass in the smelting process can be enhanced, and the strength and mechanical and chemical stability are improved; on the other hand, rare-earth elements are added, so the structure of the glass body is changed, and the performance of the glass body is improved; after the composite performance reinforcing agent and the glass body are melted, and a composite effect is generated, so that the mechanical performance of the alumina silicate glass is improved, and the alumina silicate glass is enabled to have better environmental suitability.

Description

[0001] technical field [0002] The invention relates to the field of aluminosilicate glass, and more specifically relates to a composite performance enhancer for improving the mechanical properties and chemical stability of aluminosilicate glass and reducing high-temperature viscosity. Background technique [0003] In the past ten years, the electronic information industry has developed by leaps and bounds. Portable electronic devices such as mobile phones, notebook computers and even tablet computers have entered people's lives more and more, bringing convenience to human production and life. No matter how different the functions of these electronic devices are, it is inevitable to use glass as the main component of the display system. The traditionally used soda-lime-silica glass has poor mechanical strength and wear resistance, and cannot be used for a long time and in Use in special circumstances. Especially when these electronic devices adopt touch control or handwrit...
