Crystal liquid substrate glass material and preparation method thereof

Abstract

The invention discloses a crystal liquid substrate glass material and a preparation method thereof. 50-61 percent of monox by weight percent, 8.15-11.35 percnet of boric oxide by weight percent and 10-14.5 percent of alumina by weight percent are mixed uniformly, melted at 800 DEG C-over 1000 DEG C, preserved for 6-10 hours at the temperature and cooled; the cooled mixture is pulverized and screened to obtain premix; the premix of monox, boric oxide and alumina is mixed with other components according to the following weight percentage: 1-4.5 percent of strontium caronate, 2.8-8.0 percent of bariumcarbonate, 4-9.48 percent of calcium carbonate, 0-0.5 percent of magnesium carbonate, 0-0.5 percent of zinc oxide and 4-6.0 percent of barium nitrate; and the above materials are thrown into a glass furnace after being mixed uniformly and stirred, and the crystal liquid substrate glass is finally obtained by drawing after melting at 1500 DEG C-1650 DEG C and clarification. The invention can enhance the melting capacity of glass and improve the clarification effect of glass.

Description

technical field [0001] The invention relates to the production field of liquid crystal substrate glass, in particular to a liquid crystal substrate glass raw material and a preparation method thereof. Background technique [0002] The raw materials of glass used in industrial production can be divided into two categories: main raw materials and auxiliary raw materials according to their dosage, production process and the function of products. The general glass is silicate glass, and its main component is SiO 2 、Al 2 o 3 , CaO, MgO, R 2 O.B 2 o 3 etc. The imported raw materials include quartz sand, pyrophyllite, limestone, dolomite, soda ash, borax, boric acid, feldspar, etc., in order to ensure the melting quality in the glass melting process, such as glass clarification, fluxing, coloring, decolorization, etc. are called auxiliary materials. [0003] Liquid crystal substrate glass is a special glass product, which is ultra-thin and ultra-flat to adapt to the complex ...

AI Technical Summary

Problems solved by technology

[0011] In the conventional production of liquid crystal substrate glass, defects such as air bubbles are strictly prohibited in the final product of the glass. Therefore, during the melting of the glass, a certain amount of clarifying agent must be added to the raw materials to supplement the defects of poor melting and clarifying of the glass itself. , the best clarifying agent is As 2 o 3 , but As 2 o 3 The toxicity is very strong, and it may pollute the environment during the glass manufacturing process or waste glass treatment, and its use is being restricted
