Abstract

The invention discloses a wear-resistant crystallized glass plate and a preparation method thereof. The wear-resistant crystallized glass plate consists of the following components in parts by weight: 65-85 parts of steel and iron furnace slag, 20-30 parts of quartz sand, 6-10 parts of magnesium oxide, 5-10 parts of titanium dioxide and 1-3 parts of calcium fluoride, wherein the steel and iron furnace slag comprises the following components in percentage by weight: 13-20 percent of SiO2, 10-15 percent of FeO, 40-50 percent of CaO, 5-10 percent of MgO, 2-5 percent of Al2O3, 10-20 percent of TFe, 2-5 percent of MnO2, 0.1-0.5 percent of P2O3 and 0.5-1.5 percent of MFe. The method comprises burdening, melting, water quenching, grinding, sieving, press molding, nucleating, crystallizing and rubbing down, wherein melting is performed at the temperature of 1,380-1,450 DEG C for 1-3 hours; and crystallizing is performed at the temperature of 900-920 DEG C for 1-2 hours. Compared with the prior art, the wear-resistant crystallized glass plate has the advantages of low raw material cost, excellent melting performance, excellent crystallizabitity, high plate hardness, high bending strength, soft and bright surface gloss, denseness, immaculacy and wide product market prospect.

Description

technical field [0001] The invention relates to the technical field of industrial wear-resistant plates, in particular to a wear-resistant glass-ceramic plate and a preparation method thereof. Background technique [0002] Glass-ceramics (Glass-Ceramics), also known as glass-ceramics or micro-ceramic ceramics, is a kind of glass-ceramics containing a large number of micro-crystals, which is obtained by adding a crystal nucleating agent and undergoing certain heat treatment conditions to control the crystallization of glass. polycrystalline solid material. The structure and properties of glass-ceramic are different from ceramics and glass, and its properties depend on the mineral composition and microstructure of the microcrystalline ceramic phase and the chemical composition of glass, so it combines the characteristics of ceramics and glass and has low thermal expansion Coefficient, high mechanical strength, remarkable corrosion resistance, weathering resistance and good th...
