Abstract

The invention discloses a preparation technology for a glass ceramics sheet. The preparation technology includes the steps that 1, SiO2, Al2O3, K2O, Na2O, CaO, MgO, F and a clarifying agent are weighed to obtain batch; 2, the batch is added into a melting furnace, the melting temperature is controlled to be 1510 DEG C-1520 DEG C, and the melted batch is clarified on the stirring condition to generate glass melt; 3, the glass melt enters a three-roll roller press to be rolled and calendered to form a glass plate; 4, the glass plate enters a roller kiln, and a glass ceramics sheet is obtained through primary nucleation, intensified nucleation and crystallization; 5, annealing, cooling, polishing and trimming are carried out on the obtained glass ceramics sheet to obtain the glass ceramics sheet product. The thickness of the glass ceramics sheet prepared through the preparation process according to the component content is 2-10 mm, the technical effect of bending resistance of the sheet in the production technical process is achieved, bending resistance and compressive strength are high, industrialization of the glass ceramics sheet is achieved, and market promotion is easy.
