Problems solved by technology
Due to the limitations of the process itself, the products produced by it have defects such as some pores inside the glass that are difficult to completely remove, and have defects such as low strength, poor toughness, unsatisfactory flatness of the plate, and surface defects, and the cost of main raw materials and metal oxide additives is high. , not suitable for large-scale promotion and production
It is difficult to meet the consumption demand of the current building materials market, so there is an urgent need for a newer and more practical glass-ceramic decorative plate

Embodiment 1
[0013] Embodiment 1 of the present invention, a method for preparing a non-porous novel nano-glass-ceramic decorative plate, comprises the following steps:
[0014] (1) will be made of SiO 2 , CaO, Al 2 o 3 , ZnO, Cr 2 o 3 , MgO, coal gangue, and fly ash are added to the electric furnace, heated at 1520~1630°C for 2~5h to fully melt and convert into glass liquid;
[0015] (2) 20-40% of the molten glass is made into water-tempered glass granules, and the gradation of the granules is 30-70 mesh, and the gradated water-tempered glass granules are combined with other melted glass particles The glass melt is mixed to make the mother glass;
[0016] (3) Pour the mixed mother glass into the salivating calendering machine, and pour it vertically through the tail of the salivating groove onto the rotating lower pressure roller, and through the continuous relative rotation of the upper and lower rollers, the glass is hydraulically extended to a certain thickness and width of the g...

The invention discloses a preparation method of a novel imporous nano microcrystalline glass decorative plate. The preparation method comprises the following steps: (1) adding raw materials to an electric stove to be converted into glass liquid, wherein the raw materials comprise SiO2, CaO, Al2O3, ZnO, Cr2O3, MgO, coal gangue and pulverized fuel ash; (2) preparing 20-40% of the glass liquid into water quenched glass particles, wherein the gradation of the particles is 30-70 meshes; and mixing the water quenched glass particles of the gradation with other melted glass melt to generate mother glass; (3) carrying out rolling and calendering on the mother glass to generate a glass plate, and then annealing to generate a glass raw sheet; and (4) crystallizing the glass raw sheet to obtain the microcrystalline plate. The product prepared by the method of the invention has the performance advantages of high density, wear resistance, good toughness, good planeness, zero absorption, no radiation, no need of maintenance and the like.
Description
technical field [0001] The invention relates to a method for preparing a non-porous novel nano glass-ceramic decorative plate. Background technique [0002] At present, most of the glass-ceramic decorative plates available in the domestic market adopt the production process and technology of "water-quenching sintering surface crystallization method". Due to the limitations of the process itself, the products produced by it have defects such as some pores inside the glass that are difficult to completely remove, low strength, poor toughness, unsatisfactory plate flatness, and surface defects, and the cost of main raw materials and metal oxide additives is high. , not suitable for large-scale promotion and production. It is difficult to meet the consumer demand of the current building materials market, and thus a more novel and practical glass-ceramic decorative plate is urgently needed. Contents of the invention [0003] The technical problem to be solved by the present i...
